	Contamination of impacted meteorites can happen quickly A team of scientists has published the results of an investigative survey into the Sutter's Mill meteorite that landed in California in 2012.
	SpaceX delays space station delivery until January The space station astronauts will have to wait until next month for their Christmas delivery.
	NASA considers possibilities for manned mission to Venus (Phys.org) —NASA's Systems Analysis and Concepts Directorate has issued a report outlining a possible way for humans to visit Venus, rather than Mars—by hovering in the atmosphere instead of landing on the surface. The hovering vehicle, which they call a High Altitude Venus Operational Concept (HAVOC), would resemble a blimp with solar panels on top, and would allow people to do research just 50 kilometers above the surface of the planet.
	Chandra weighs most massive galaxy cluster in distant universe (Phys.org) —Using NASA's Chandra X-ray Observatory, astronomers have made the first determination of the mass and other properties of a very young, distant galaxy cluster.
	Two astronauts will expand envelope with one-year spaceflight The two men assigned to a one-year spaceflight said Thursday that their upcoming mission will allow the world to push deeper into space.
	Kepler proves it can still find planets To paraphrase Mark Twain, the report of the Kepler spacecraft's death was greatly exaggerated. Despite a malfunction that ended its primary mission in May 2013, Kepler is still alive and working. The evidence comes from the discovery of a new super-Earth using data collected during Kepler's "second life."
	German named next head of European Space Agency Johann-Dietrich Woerner, head of German aerospace giant DLR, is to succeed Frenchman Jean-Jacques Dordain as next director-general of the European Space Agency, ESA announced on Thursday.

Medicine & Health news

	Life expectancy increases globally as death toll falls from major diseases People are living much longer worldwide than they were two decades ago, as death rates from infectious diseases and cardiovascular disease have fallen, according to a new, first-ever journal publication of country-specific cause-of-death data for 188 countries.
	Fine particulate air pollution linked with increased autism risk Women exposed to high levels of fine particulate matter specifically during pregnancy—particularly during the third trimester—may face up to twice the risk of having a child with autism than mothers living in areas with low particulate matter, according to a new study from Harvard School of Public Health (HSPH). The greater the exposure, the greater the risk, researchers found. It was the first U.S.-wide study exploring the link between airborne particulate matter and autism.
	2,500-year-old Pythagoras theorem helps to show when a patient has turned a corner A medical researcher at the University of Warwick has found the 2,500 year-old Pythagoras theorem could be the most effective way to identify the point at which a patient's health begins to improve.
	Healthy brain development balanced on edge of a cellular 'sword' A new Yale-led study of children with neurodevelopmental abnormalities of the brain identifies a "cutting" enzyme crucial to the shaping and division of brain cells as well as the replenishment of neural stem cells.
	Scientists locate homing signal in brain, explaining why some people are better navigators The part of the brain that tells us the direction to travel when we navigate has been identified by UCL scientists, and the strength of its signal predicts how well people can navigate.
	Scientists discover tiny gene fragments linked to brain development and autism Very small segments of genes called "microexons" influence how proteins interact with each other in the nervous system, scientists at the University of Toronto have found, opening up a new line of research into the cause of autism.
	Could ibuprofen be an anti-aging medicine? Popular over-the counter drug extends lifespan in yeast, worms and flies Ibuprofen, a common over-the-counter drug used to relieve pain and fever, could hold the keys to a longer healthier life, according to a study by researchers at the Buck Institute for Research on Aging. Publishing in PLoS Genetics on December 18th, scientists showed that regular doses of ibuprofen extended the lifespan of yeast, worms and fruit flies.
	'Deep learning' reveals unexpected genetic roots of cancers, autism and other disorders In the decade since the genome was sequenced in 2003, scientists and doctors have struggled to answer an all-consuming question: Which DNA mutations cause disease?
Scientists identify new and beneficial function of endogenous retroviruses in immune response Retroviruses are best known for causing contagious scourges such as AIDS, or more sporadically, cancer.
Five things to know: Alcohol calorie labels on menus Want to know how many calories are in that alcoholic drink you're about to order? You might be able to find out just by reading the menu.
New hope for rare disease drug development Using combinations of well-known approved drugs has for the first time been shown to be potentially safe in treating a rare disease, according to the results of a clinical trial published in the open access Orphanet Journal of Rare Diseases. The study also shows some promising preliminary results for the efficacy of the drug combination.
	New evidence shows electronic cigarettes facilitate smoking cessation Do electronic cigarettes help smokers to quit? Yes, but.... New Cochrane review finds emerging evidence that smokers who use electronic cigarettes can stop or reduce their smoking.
Laparoscopic surgery for bladder cancer leads to good long-term cancer control Long-term survival rates following laparoscopic surgery for bladder cancer are comparable to those of open surgery, according to a study published in BJU International. The findings, which come from the largest study to date with long-term follow-up after this type of minimally invasive surgery, indicate that prospective randomized trials comparing these two bladder cancer surgeries are warranted.
High-dose flu vaccine appears better for frail older adults in long-term care About 90 percent of the deaths associated with influenza in the U.S. annually are among adults aged 65 and older, according to estimates from the Centers for Disease Control and Prevention (CDC). Those 85 and older who live in long-term care facilities are particularly at risk: They are more likely to be exposed to influenza, their immune systems are not as responsive to vaccines, and other medications or medical conditions may impair their immunity.
Early caregiving experiences have long-term effects on social relationships, achievement Do the effects of early caregiving experiences remain or fade as individuals develop? A new study has found that sensitive caregiving in the first three years of life predicts an individual's social competence and academic achievement, not only during childhood and adolescence, but also into adulthood.
The quality of parent-infant relationships and early childhood shyness predict teen anxiety Infants who frequently react to unfamiliar objects, people, and situations by becoming afraid and withdrawing are referred to as having a behaviorally inhibited temperament. As these infants grow up, many continue to be inhibited or reticent when they experience new things, including meeting new people. Inhibited children are more likely than their peers to develop anxiety problems, especially social anxiety, as they get older. A new longitudinal study has found that behavioral inhibition that persists across early childhood is associated with social anxiety in adolescence, but only among youth who were insecurely attached to their parents as infants.
Study shows epinephrine auto-injectors and asthma inhalers used incorrectly Millions of Americans with severe allergies and asthma are prescribed medical devices to help relieve symptoms and sometimes, to treat potentially fatal allergic reactions. Unfortunately, very few people use their prescribed medical devices properly - even if they think they know how.
Moms of food-allergic kids need dietician's support Discovering your child has a severe food allergy can be a terrible shock. Even more stressful can be determining what foods your child can and cannot eat, and constructing a new diet which might eliminate entire categories of foods.
	How does prostate cancer form? Prostate cancer affects more than 23,000 men this year in the USA however the individual genes that initiate prostate cancer formation are poorly understood. Finding an enzyme that regulates this process could provide excellent new prevention approaches for this common malignancy. Sirtuin enzymes have been implicated in neurodegeneration, obesity, heart disease, and cancer. Research published online Thursday in The American Journal of Pathology show the loss of one of sirtuin (SIRT1) drives the formation of early prostate cancer (prostatic intraepithelial neoplasia) in mouse models of the disease.
	Subtle but important memory function affected by preterm birth A new study has found that children born prematurely show differences in a subtle but important aspect of memory: the ability to form and retrieve memories about context, such as what, when, and where something happened. This type of memory is important, but can be missed on the usual set of direct assessments. The new research suggests that it may be valuable to find targeted ways to help strengthen this aspect of memory in children born preterm.
	Researcher to cancer: 'Resistance will be futile' Turning the tables, Katherine Borden at the University of Montreal's Institute for Research in Immunology and Cancer (IRIC) has evoked Star Trek's Borg in her fight against the disease. "Cancer cells rapidly evolve a multitude of defense mechanisms to evade the effects of the oncologist's drug arsenal. Unfortunately, clinical strategies to overcome these lag far behind," Borden explained. "This mismatch likely underlies our inability to implement new durable treatment strategies." However, in her paper published in Cancer Research entitled "When will resistance be futile?", Borden describes one way that cancer goes about this evolution, providing researchers with a possible tool for disarming this defense. The article is inspired by research she published in Nature with her doctoral student Hiba Zahreddine.
Colombia village's 'curse' could hold Alzheimer's cure When John Jairo, a meticulous night watchman, lost his job for leaving all of his employer's doors open, his family knew they were hit by the "Yarumal curse."
Many children and adolescents get too much caffeine from energy drinks When children aged 10-14 consume energy drinks, one in five consumes too much caffeine. When their caffeine intake from other sources such as cola and chocolate is included, every second child and more than one in three adolescents aged 15-17 consume too much caffeine. This is the finding of a new study conducted by the National Food Institute, Technical University of Denmark. The institute estimates that energy drinks cause or contribute to a large proportion of children and adolescents exceeding the recommended maximum daily intake of caffeine.
	Hypertension medication that targets stress may help smokers quit Smokers trying to quit often light up a cigarette to deal with stress. Now an interdisciplinary team of Yale researchers has shown that guanfacine, a medication approved for treating hypertension that reduces stress and enhances cognition, shows promise as a smoking cessation aid.
	3-D printed device relieves sleep apnoea Sleep apnoea is a condition where the air passage in the throat becomes blocked during sleep and causes people to stop breathing.

	In the battle against Ebola, a double-layer solution When working with Ebola patients, protective gear works, but removing it can be harrowing. Seeking to protect health care workers from the precarious nature of taking off soiled gloves, Cornell students have developed a duplex solution to a complex problem: a double-layer system.
	Scientists investigate use of cognitive computing-based visual analytics for skin cancer image analysis IBM announced today a collaboration with Memorial Sloan Kettering to research the application of cognitive computing to analyze dermatological images of skin lesions with the goal of assisting clinicians in the identification of various cancerous disease states. The technology, which learns by identifying specific patterns in medical images, has the potential to increase the number of cases detected and help clinicians make earlier diagnoses.
	Natural quit smoking remedy more effective than nicotine replacement New Zealand researchers have found that a low cost, plant-based product marketed for smoking cessation in parts of Europe for the last 40 years, is better than nicotine replacement therapy at helping smokers quit.
	Cars carrying children to become smoke-free New legislation has been announced that will make it illegal to smoke in a vehicle that is carrying a child.
	Study finds genetic clue to menopause-like condition in young women Six young women with a disorder that mimics menopause have gene alterations that hamper the repair of damaged DNA, report researchers supported by the National Institutes of Health. The mutations, occurring in women with primary ovarian insufficiency (POI), are in genes that repair damaged DNA in cells of the ovary that eventually become egg cells. The findings may contribute to an understanding of POI, and to the genetic basis of the precise timing of menopause that occurs at the usual stage in a woman's life.
	Chronic high blood sugar may be detrimental to the developing brain of young children Young children who have long-term high blood sugar levels are more likely to have slower brain growth, according to researchers at centers including the National Institutes of Health.
Could trophoblasts be the immune cells of pregnancy? Trophoblasts, cells that form an outer layer around a fertilized egg and develop into the major part of the placenta, have now been shown to respond to inflammatory danger signals, researchers from Norwegian University of Science and Technology (NTNU) found in a recent study published in Journal of Reproductive Immunology, December 2014.
	Cells identified that enhance tumor growth and suppress anti-cancer immune attack A study led by St. Jude Children's Research Hospital scientists has identified the population of white blood cells that tumors use to enhance growth and suppress the disease-fighting immune system. The results, which appear in the December 18 edition of the scientific journal Immunity, mark a turning point in cancer immunology and provide the foundation for developing more effective immunotherapies.
	EU court says obesity can be disability (Update) The European Union's highest court ruled Thursday that obesity can be considered a "disability" if it hinders an overweight person's performance at work.
	Is the government stalling on plain cigarette packaging? We are still waiting to hear whether the UK government will rule in that all tobacco products should be placed in standardised packaging.
	Athletes urged to drink when thirsty after Rottnest swim incident Long distance swimmers are being urged to drink when they are thirsty rather than to a set schedule after a woman was admitted to intensive care with critically low sodium levels following last year's Rottnest Channel Swim.
Low-dose lithium prevents Parkinson's symptoms in aged mice with a human mutation for the disease Low-dose lithium prevented symptoms of Parkinson's disease in aged mice genetically engineered to develop the incurable, degenerative motor disease that is diagnosed in about 60,000 Americans each year. The research, led by Buck Institute faculty Julie Andersen, PhD, showed that lithium prevented the motor impairment and dopaminergic loss that are hallmarks of the disease. The study is now online in the journal Brain Research.

	First of new generation of cancer drugs granted European approval A new drug for ovarian cancer, developed by researchers at the University of Cambridge and AstraZeneca, has today become the first of new class of drugs, known as PARP-inhibitors, to be granted approval anywhere in the world. The drug, Lynparza, has been granted Marketing Authorisation from the European Commission.
	Low premiums yet big bills – why high-deductible health plans need reform A few years ago, we met Angie, a hair salon owner in Oregon with health insurance coverage and a stack of unpaid medical bills. She and her husband were both employed – he as a carpenter—and earned about US$45,000 a year, a bit less than the median income in their county. They were raising two children. Their health insurance had a deductible of US$4,000 for each person, capped at US$8,000 for the family, which meant they had to pay that much before benefits would kick in.
Wild blueberries (bilberries) can help tackle the adverse effects of a high-fat diet Eating bilberries diminishes the adverse effects of a high-fat diet, according to a recent study at the University of Eastern Finland. For the first time, bilberries were shown to have beneficial effects on both blood pressure and nutrition-derived inflammatory responses.
Why do parents who usually vaccinate their children hesitate or refuse? A new study by Dr. Anat Gesser-Edelsburg, Dr. Yaffa Shir-Raz and Prof. Manfred S. Green from University of Haifa, School of Public Health, published in the Journal of Risk Research suggests that even parents who are not "vaccine refusers" and who usually comply with the routine vaccination programs may hesitate or refuse to vaccinate their children based on poor communication from the relevant healthcare provider, as well as concerns about the safety of the vaccine.
	New disease mechanism discovered in lymphoma Programmed cell death is a mechanism that causes defective and potentially harmful cells to destroy themselves. It serves a number of purposes in the body, including the prevention of malignant tumor growth. Now, researchers at Technische Universität München (TUM) have discovered a previously unknown mechanism for regulating programmed cell death. They have also shown that patients with lymphoma often carry mutations in this signal pathway.
	Researchers treat heart attacks with new gene therapy based on telomerase enzyme The enzyme telomerase repairs cell damage produced by ageing, and has been used successfully in therapies to lengthen the life of mice. Now it has been observed that it could also be used to cure illnesses related to the ageing process. Researchers at the Spanish National Cancer Research Centre (CNIO) have for the first time treated myocardial infarction with telomerase by designing a very innovative strategy: a gene therapy that reactivates the telomerase gene only in the heart of adult mice, thus increasing survival rates in those animals by 17 % following a heart attack.
Researchers ferret out a flu clue Research that provides a new understanding as to why ferrets are similar to humans is set to have major implications for the development of novel drugs and treatment strategies.
Specific oxidation regulates cellular functions For a long time, hydrogen peroxide has been considered as a dangerous metabolite that can damage cells through oxidation. This, however, is not its only role in the cell. Scientists from the German Cancer Research Center have now discovered how it also transmits specific signals: Enzymes called peroxiredoxins catch the free hydrogen peroxide molecules and use them to specifically oxidize other proteins. Hydrogen peroxide thus regulates, for example, the activity of an inflammation-promoting transcription factor and hence controls important cellular functions.
Tailor-made cancer treatments? New cell culture technique paves the way In a development that could lead to a deeper understanding of cancer and better early-stage treatment of the disease, University of Michigan researchers have devised a reliable way to grow a certain type of cancer cells from patients outside the body for study.
Preventing hepatitis C patients from being lost in the health-care system A new study shows that many patients infected with the hepatitis C virus (HCV) are lost during different stages of health care to manage the disease. This real-life' view of the HCV patient care continuum in a major U.S. urban area is published in Hepatology, a journal of the American Association for the Study of Liver Diseases, and highlights the importance of generating awareness among clinicians and at-risk groups about appropriate HCV testing, referral, support and care.
Islet cell transplantation restores type 1 diabetics' blood sugar defense mechanisms Type 1 diabetes (T1D) patients who have developed low blood sugar (hypoglycemia) as a complication of insulin treatments over time are able to regain normal internal recognition of the condition after receiving pancreatic islet cell transplantation, according to a new study led by researchers at the Perelman School of Medicine at the University of Pennsylvania, published online in Diabetes. Severe hypoglycemia—a life-threatening complication of insulin treatment for T1D—can occur when the body's defense mechanisms against low blood sugar are broken down over a long period of time, causing shakiness, irritability, confusion, lightheadedness, shortness of breath, and even seizures or loss of consciousness.
	Resting heart rate predicts renal outcomes in high-risk patients (HealthDay)—For patients at high risk of cardiovascular disease, resting heart rate (RHR) can predict renal outcomes, according to research published online Nov. 27 in the Journal of Internal Medicine.
Scientists map out how childhood brain tumors relapse Researchers have discovered the unique genetic paths that the childhood brain tumour medulloblastoma follows when the disease comes back, according to research published in Cancer Cell today.
	Trigger mechanism for recovery after spinal cord injury revealed After an incomplete spinal cord injury, the body can partially recover basic motor function. So-called muscle spindles and associated sensory circuits back to the spinal cord promote the establishment of novel neuronal connections after injury. This circuit-level mechanism behind the process of motor recovery was elucidated by Prof. Silvia Arber's research group at the Biozentrum, University of Basel and the Friedrich Miescher Institute for Biomedical Research. Their findings may contribute to designing novel strategies for treatment after spinal cord injuries and have now been published in the journal Cell.
	23andMe study sketches genetic portrait of the US 23andMe today announced the publication of a study that pinpoints fine-scale differences in genetic ancestry of individuals from across the United States.
	Tackling neurotransmission precision Behind all motor, sensory and memory functions, calcium ions are in the brain, making those functions possible. Yet neuroscientists do not entirely understand how fast calcium ions reach their targets inside neurons, and how that timing changes neural signaling. Researchers at the Okinawa Institute of Science and Technology Graduate University have determined how the distance from calcium channels to calcium sensors on vesicles affects a neuron's signaling precision and efficacy.
	Self-reported daily exercise associated with lower blood pressure, glucose readings Self-reported moderate to vigorous exercise was associated with lower blood pressure and blood glucose levels in a Kaiser Permanente study published in the journal Preventing Chronic Disease. Data collected from Kaiser Permanente's Exercise as a Vital Sign (EVS) program, in which medical office staff asks patients about their exercise habits at every health care visit, revealed associations between moderate to vigorous exercise and improved measures of cardiometabolic health for both men and women. Few previous studies have examined associations between self-reported physical activity and cardiometabolic risk factors within a health care setting.
Change of diet to unmask cancer vulnerabilities and reduce cancer risk Many recent studies showed that calorie restrictions reduce the incidence of cancer, whereas high-calorie diets cause obesity and diabetes, both of which increase the risk of developing cancers. However, tumor biology still hides complex mechanisms, as revealed by researchers from the Faculty of Medicine of the University of Geneva (UNIGE), Switzerland. In a study published in Cell Metabolism, scientists not only found the unexpected benefit that a change of diet had on certain types of lung cancer, they also deciphered the molecular mechanism underlying this dietary effect and showed how this cancer vulnerability could be exploited in targeted treatment strategies with limited side effects.
	What makes kids generous? Neuroscience has some answers It's no secret that people are judgmental, and young children are no exception. When children witness "good" or "bad" behavior, their brains show an immediate emotional response. But, according to a study appearing in the Cell Press journal Current Biology on December 18, it takes more than that kind of automatic moral evaluation for kids to act with generosity and share their stickers.
	Internet addiction affects six percent of people worldwide Internet addiction is an impulse-control problem marked by an inability to inhibit Internet use, which can adversely affect a person's life, including their health and interpersonal relationships. The prevalence of Internet addiction varies among regions around the world, as shown by data from more than 89,000 individuals in 31 countries analyzed for a study published in Cyberpsychology, Behavior, and Social Networking.
New technique provides novel approach to diagnosing ciliopathies Cilia, the cell's tails and antennas, are among the most important biological structures. They line our windpipe and sweep away all the junk we inhale; they help us see, smell and reproduce. When a mutation disrupts the function or structure of cilia, the effects on the human body are devastating and sometimes lethal.
	Fast-changing genes help malaria to hide in the human body A study of the way malaria parasites behave when they live in human red blood cells has revealed that they can rapidly change the proteins on the surface of their host cells during the course of a single infection in order to hide from the immune system.
Team finds bacterial infections differ based on geography, healthcare spending Where you live affects the type of bacteria that cause bloodstream infections, according to researchers at Rhode Island Hospital and an international team of investigators. The closer you live to the equator, the greater the likelihood of a bloodstream infection caused by a group of bacteria called Gram-negative bacteria, which thrive in warm and moist environments, compared to another group of bacteria referred to as Gram-positive bacteria. The study also found that the proportion of a country's GDP spent on health care impacted the type of bacteria causing such infections. The study was published in the scientific journal PLOS ONE.
	How llamas' unusual antibodies might help in the fight against HIV/AIDS Most vaccines work by inducing an immune response characterized by neutralizing antibodies against the respective pathogen. An effective HIV vaccine has remained elusive so far, but researchers have continued to make progress, often employing innovative methods. A study published on December 18th in PLOS Pathogens reports that a combination of antibodies from llamas can neutralize (destroy) a wide range of circulating HIV viruses.
Local enforcement of federal immigration laws affects immigrant Hispanics' healthcare State and local enforcement of federal immigration laws can have an adverse impact on the use of health care services by immigrant Hispanics, according to a North Carolina-based study by Wake Forest Baptist Medical Center researchers.
	Ability to balance on one leg may reflect brain health and stroke risk Struggling to balance on one leg for 20 seconds or longer was linked to an increased risk for small blood vessel damage in the brain and reduced cognitive function in otherwise healthy people with no clinical symptoms, according to new research in the American Heart Association's journal Stroke.
	People with blood groups A, B and AB at higher risk of type 2 diabetes than group O A study of more than 80,000 women has uncovered different risks of developing type 2 diabetes associated with different blood groups, with the biggest difference a 35% increased risk of type 2 diabetes found in those with group B, Rhesus factor positive (R+) blood compared with the universal donor group O, Rhesus factor negative (R-). The study is published in Diabetologia (the journal of The European Association for the Study of Diabetes) and is by Dr Guy Fagherazzi, and Dr Françoise Clavel-Chapelon, Center for Research in Epidemiology and Population Health, INSERM, Villejuif, France, and colleagues.
Less than half of UK prescriptions for antipsychotics issued for main licensed conditions Less than half of UK prescriptions for antipsychotic drugs are being issued to treat the serious mental illnesses for which they are mainly licensed, reveals research published in the online journal BMJ Open.
Urban stressors may contribute to rising rate of diabetes in developing nations As people in developing nations relocate from rural areas to cities, the increased stress is affecting their hormone levels and making them more susceptible to diabetes and other metabolic disorders, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Resistance to anti-viral drug may be more likely in cystic fibrosis patients A drug called ganciclovir is given to lung transplant patients to protect against a life-threatening virus that is common after transplantation.
	Mutations need help from aging tissue to cause leukemia Why are older people at higher risk for developing cancer? Prevailing opinion holds that, over time, your body's cells accumulate DNA damage and that eventually this damage catches up with the body in a way that causes cancer. A University of Colorado Cancer Center study published today in the journal Aging shows that this prevailing opinion is incomplete. In addition to DNA damage, cancer depends on the slow degradation of tissue that surrounds cancer cells, something that naturally comes with aging.
	Study finds enzyme inhibitors suppress herpes simplex virus replication Saint Louis University research findings published in the December issue of Antimicrobial Agents and Chemotherapy report a family of molecules known as nucleotidyltransferase superfamily (NTS) enzyme inhibitors are promising candidates for new herpes virus treatments.
Hot flashes linked to increased risk of hip fracture Women who experience moderate to severe hot flashes and night sweats during menopause tend to have lower bone mineral density and higher rates of hip fracture than peers who do not have menopausal symptoms, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
Cell-associated HIV mucosal transmission: The neglected pathway Dr. Deborah Anderson from Boston University School of Medicine (BUSM) and her colleagues are challenging dogma about the transmission of the human immunodeficiency virus type 1 (HIV-1). Most research has focused on infection by free viral particles, while this group proposes that HIV is also transmitted by infected cells. While inside cells, HIV is protected from antibodies and other antiviral factors, and cell-to-cell virus transmission occurs very efficiently through intercellular synapses. The Journal of Infectious Diseases (JID) has devoted their December supplement to this important and understudied topic.
	Research shows E.B. White was right in Charlotte's Web Before Charlotte the spider spelled the word "humble" in her web to describe Wilbur the pig, she told Templeton the rat that the word meant "not proud."
High socioeconomic status increases discrimination, depression risk in black young adults An investigation into factors related to disparities of depression in young adults has found that higher parental education - which has a protective effect for white youth - can also increase the risk of depression for black youth. The MassGeneral Hospital for Children (MGHfC) study published online in the Journal of Pediatrics also found that, among high-socioeconomic-status black youth, greater perceptions of being discriminated against cancelled out the protective effects of parental education.
	Most states not ready to handle infectious disease outbreaks: report (HealthDay)—Ebola's entrance into the United States—along with Angelina Jolie's chickenpox and the National Hockey League's mumps outbreak—have highlighted cracks in the nation's public health defense against infectious disease, according to a new health policy report released Thursday.
	Many flu infections aren't good match for vaccine: CDC (HealthDay)—The flu is starting to tighten its grip on much of the United States, particularly in the South and Midwest, U.S. health officials reported Thursday.
