Chemistry news

	New spectroscopy technique provides unprecedented insights about the reactions powering fuel cells esearchers at UCLA's California NanoSystems Institute have developed a dramatically advanced tool for analyzing how chemicals called nanocatalysts convert chemical reactions into electricity.
	Scientists discover precise location of active sites on popular catalyst If you want to change a situation, it's often best to get to the heart of the matter. For chemists, this often means delving into the active sites of catalysts, which speed the reactions behind billions of dollars worth of chemicals and other products. Active sites are where the reaction actually happens. If active sites work slowly or fail quickly, the result is higher costs and lower production rates. To make better active sites, scientists need to see the sites. For the first time, a team led by researchers at Pacific Northwest National Laboratory saw the active sites on a well-known vanadium-based catalyst.

	How beneficial bacteria protect intestinal cells Research on a helpful part of the microbiome—beneficial intestinal bacteria—is moving from "what is there" to "how they help."
	Researchers track the neural circuits driving a fly's choice of a mate If you've ever found a banana overtaken by a swarm of tiny flies, you were in fact witnessing an orgy of amorous Drosophila melanogaster. These trespassers engage in fervent courtship and mating atop ripe fruits, and the sex is anything but casual. In particular, male flies are very precise in choosing whom to court—a complex and intuitive decision that has fascinated scientists for more than a century.
	How do ants identify different members of their society? Ants, which are eusocial insects, have intrigued scientists for long as a model for cooperation inside a colony where they nurse the young, gather food and defend against intruders. Most recently, ants have been shown to cooperate when transporting big chunks of food, they have been studied for how they manage to keep clean, and they have been examined also for why most of them in a colony are lazy. Add to this list now how ants identify different members of their colony from other colonies.
	Team discovers the ancient origins of deadly Lassa virus Working as part of an international team in the United States and West Africa, a researcher at The Scripps Research Institute (TSRI) has published new findings showing the ancient roots of the deadly Lassa virus, a relative of Ebola virus, and how Lassa virus has changed over time.
	Alert to biologists: Ribosomes can translate the 'untranslated region' of messenger RNA In what appears to be an unexpected challenge to a long-accepted fact of biology, Johns Hopkins researchers say they have found that ribosomes—the molecular machines in all cells that build proteins—can sometimes do so even within the so-called untranslated regions of the ribbons of genetic material known as messenger RNA (mRNA).
	Humans responsible for demise of gigantic ancient mammals Early humans were the dominant cause of the extinction of a variety of species of giant beasts, new research has revealed.
	When fruit flies get sick, their offspring become more diverse New research from North Carolina State University and Reed College shows that when fruit flies are attacked by parasites or bacteria they respond by producing offspring with greater genetic variability. This extra genetic variability may give the offspring an increased chance of survival when faced with the same pathogens. These findings demonstrate that parents may purposefully alter the genotypes of their offspring.
	Determining America's most lethal animal Animal attacks have been in the news a lot. Late last year, a 22-year-old student in New Jersey was killed by a black bear he had been photographing. This summer, swimmers off the coast of North Carolina have suffered a record number of shark attacks, several of which resulted in amputations. And early in July, a 28-year-old Texas swimmer who ignored warning signs was killed by an alligator.

	When a 'UFO' flies by, does it bother bears? If an unidentified flying object suddenly appeared in the sky, it's likely your heart would beat faster. Now, researchers reporting in the Cell Press journal Current Biology on August 13 have found that the same is true for bears.
	Diversity provides stability among the animals in the wild Why some species of plants and animals vary more in number than others is a central issue in ecology. Now researchers at Linnaeus University in Sweden and from the Helmholtz Centre for Environmental Research (UFZ) have found an important finding to answer this question: Individual differences have a positive and stabilizing effect on the number of moths. Species with varying colour drawing are generally more numerous and fluctuate less in number from year to year. The results were recently published in the internationally renowned journal Proceedings of the Royal Society B. This could help to explain why some insect species in some years are very abundant pests and cause substantial damage in agriculture and forestry.
	Biochemist studies oilseed plants for biofuel, industrial development A Kansas State University biochemistry professor has reached a milestone in building a better biofuel: producing high levels of lipids with modified properties in oil seeds.
Critically endangered species successfully reproduced using frozen sperm Black-footed ferrets, a critically endangered species native to North America, have renewed hope for future survival thanks to successful efforts by a coalition of conservationists, including scientists at Lincoln Park Zoo, to reproduce genetically important offspring using frozen semen from a ferret who has been dead for approximately 20 years. The sire, "Scarface," as he is affectionately called by the team, was one of the last 18 black-footed ferrets to exist in the world in the 1980s. Eight kits, including offspring of Scarface, were born recently, significantly increasing the gene diversity of this endangered population that a dedicated team is working to recover in the wild.

Medicine & Health news

	Biologists find malaria parasites lost drug resistance after health policy changes (Medical Xpress)—Chloroquine (CQ) is a first-line treatment for Plasmodium falciparum infections, which like many other malaria treatments, eventually resulted in the selection of parasites with resistance to the drug. The evolutionary dynamics of antimalarial drug resistance are driven by many factors, including differing transmission contexts and new drug pressures on parasites. Recently, a group of researchers published a study in the Proceedings of the National Academy of Sciences that examined the loss of CQ resistance (CQR) in French Guiana following a health policy change.
	Asthma cells scramble like 'there's a fire drill' In people with asthma, the cells that line the airways in the lungs are unusually shaped and "scramble around like there's a fire drill going on." But according to a study at the Harvard T.H. Chan School of Public Health, an unexpected discovery suggests intriguing new avenues both for basic biological research and for therapeutic interventions to fight asthma.
	Newly discovered cells regenerate liver tissue without forming tumors The mechanisms that allow the liver to repair and regenerate itself have long been a matter of debate. Now researchers at University of California, San Diego School of Medicine have discovered a population of liver cells that are better at regenerating liver tissue than ordinary liver cells, or hepatocytes. The study, published August 13 in Cell, is the first to identify these so-called "hybrid hepatocytes," and show that they are able to regenerate liver tissue without giving rise to cancer. While most of the work described in the study was done in mouse models, the researchers also found similar cells in human livers.
	Low-fat diet results in more fat loss than low-carb diet in humans A study from the US National Institutes of Health presents some of the most precise human data yet on whether cutting carbs or fat has the most benefits for losing body fat. In a paper published August 13 in Cell Metabolism, the researchers show how, contrary to popular claims, restricting dietary fat can lead to greater body fat loss than carb restriction, even though a low-carb diet reduces insulin and increases fat burning.
	Exercise-induced hormone irisin is not a 'myth' Irisin, a hormone linked to the positive benefits of exercise, was recently questioned to exist in humans. Two recent studies pointed to possible flaws in the methods used to identify irisin, with commercially available antibodies. In Cell Metabolism on August 13, the Harvard scientists who discovered irisin address this contentious issue by showing that human irisin circulates in the blood at nanogram levels and increases during exercise.
	Scientists discover what controls waking up and going to sleep Fifteen years ago, an odd mutant fruit fly caught the attention and curiosity of Dr. Ravi Allada, a circadian rhythms expert at Northwestern University, leading the neuroscientist to recently discover how an animal's biological clock wakes it up in the morning and puts it to sleep at night.

Depression, stress, anxiety and anger compound CVD risk in RA patients New research reveals that depressive symptoms, stress, anxiety, and anger and lack of social support in patients with rheumatoid arthritis (RA) were linked to atherosclerosis—a build-up of fatty deposits in the arteries that contributes to cardiovascular disease. The study published in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR), suggests that screening and treatment of psychosocial symptoms may curb the cardiovascular disease burden in RA patients.
Chickenpox continues to decline in US thanks to vaccination Since the chickenpox vaccine became available in the U.S. in 1995, there has been a large reduction in chickenpox cases. Hospitalizations and outpatient visits for chickenpox have continued their decline after a second dose of the vaccine was recommended to improve protection against the disease, according to a new study published in the Journal of the Pediatric Infectious Diseases Society. The findings also suggest that increasing vaccination coverage against the once common childhood illness helps protect those who are not immunized themselves.
	Overreliance on imagination may be a sign of obsessive-compulsive disorder Confusing reality with imagination and losing contact with reality are two key characteristics that could play a role in the development of obsessive-compulsive disorder (OCD). This is what we learn from a study conducted by researchers at the CIUSSS de l'Est-de-l'Île-de-Montréal (Institut universitaire en santé mentale de Montréal) and the University of Montreal, the results of which were published in the Journal of Clinical Psychology.

	Why revealing an autism diagnosis is advisable when going to university Students with autism or Asperger's Syndrome who are preparing to go to university this autumn will be better supported by both professional services and their peers if they reveal their diagnosis, rather than keeping it disclosed, according to new research from psychologists at our University.
	Forget Freud, research on dream imagery may help us understand consciousness Rapid eye movements (REMs) during sleep may contribute to the visual part of our dreams by acting as a switch from image to image, researchers have found. The study, which measured the activity of individual cells in the brain in both awake and sleeping participants, is important because it is the first of its kind and provides a great starting point for uncovering the deeper secrets of human consciousness.
Enhancing absorption and bioavailability of curcumin and turmeric Few natural products have demonstrated the range of protective and therapeutic promise as have turmeric and its principal bioactive components, the curcuminoids. Success in translating this potential into tangible benefits has been limited by inherently poor intestinal absorption, rapid metabolism, and limited systemic bioavailability. Seeking to overcome these limitations, food ingredient formulators have begun to employ a variety of approaches to enhance absorption and bioavailability.
Endoscopic cancer detection in real time Cancer or no cancer? This question can usually only be answered after a days-long wait for a histological examination. With the use of a mass spectrometric technique, the answer may soon be available in real time. In the journal Angewandte Chemie, a team of British and Hungarian researchers has now introduced an endoscopic system that can differentiate between malignant tumors and benign polyps in the gastrointestinal tract based on the characteristic mass spectra of different layers of tissue.

	Screening for breast / ovarian cancer risk genes other than BRCA1/2 is clinically valuable A study by researchers at three academic medical centers has shown that screening women with a suspected risk of hereditary breast or ovarian cancer for risk-associated genes other than BRCA1 and 2 provides information that can change clinical recommendations for patients and their family members. The report from a team led by a Massachusetts General Hospital (MGH) Cancer Center investigator is being published in the August issue of JAMA Oncology.
	Fears of potentially blinding complication from Avastin eye injections overblown, study says Eye injections of the drug Avastin, used to treat retinal diseases, bring no greater risk of endophthalmitis, a potentially blinding eye infection, than injections with the much more expensive drug Lucentis made by the same company, according to new research from the Perelman School of Medicine at the University of Pennsylvania. Their findings are published today in JAMA Ophthalmology.
	New research helps explain why a deadly blood cancer often affects children with malaria In equatorial Africa, a region of the globe known as the "lymphoma belt," children are ten times more likely than in other parts of the world to develop Burkitt's lymphoma, a highly aggressive blood cancer that can be fatal if left untreated. That area is also plagued by high rates of malaria, and scientists have spent the last 50 years trying to understand how the two diseases are connected.
	Corrected protein structure reveals drug targets for cancer, neurodegenerative diseases Protein Kinase C (PKC) is a family of enzymes that controls the activity of other proteins in a cell by attaching chemical tags. That simple act helps determine cell survival or death. When it goes awry, a number of diseases may result. In a study published August 13 in Cell Reports, researchers at University of California, San Diego School of Medicine reveal a more accurate structure of PKC, providing new targets for fine-tuning the enzyme's activity as needed to improve human health.
	Epstein-Barr virus vaccine elicits potent neutralizing antibodies in animals Researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and their collaborators have developed an experimental, nanoparticle-based vaccine against Epstein-Barr virus (EBV) that can induce potent neutralizing antibodies in vaccinated mice and nonhuman primates. Microscopic particles, known as nanoparticles, are being investigated as potential delivery vehicles for vaccines. The scientists' findings suggest that using a structure-based vaccine design and self-assembling nanoparticles to deliver a viral protein that prompts an immune response could be a promising approach for developing an EBV vaccine for humans.
	Smoking ban linked to drop in stillbirths and newborn deaths Stillbirths have dropped by almost eight per cent in England since the smoking ban was introduced, research shows.
	New research reveals unintended consequences of using incorrect medical foods in managing patients Many "medical foods" are designed to help manage patients with rare inborn errors of metabolism (IEMs), and can help prevent serious and life-threatening complications. However, such special foods may cause harm in some patients when their use is not carefully monitored and managed, according to a research team led by scientists at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health. The researchers contend that there is a need for more rigorous clinical study of dietary management practices for patients with IEMs, including any associated long-term side effects, which may in turn result in the need to reformulate some medical foods.
Mobile technology may help people improve health behaviors Smartphone applications and wearable sensors have the potential to help people make healthier lifestyle choices, but scientific evidence of mobile health technologies' effectiveness for reducing risk factors for heart disease and stroke is limited, according to a scientific statement from the American Heart Association, published in the association's journal Circulation.

COPD patients with psychological conditions have higher rate of early hospital readmission Researchers from The University of Texas Medical Branch at Galveston found that people with a psychological condition such as depression, anxiety, psychosis, or alcohol/drug abuse are more likely to be readmitted early into a hospital for complications of chronic obstructive pulmonary disease. The study was recently published in the journal, Chest.
Dentists tapped for new role: Drug screenings A visit to the dentist has the potential to be more than a checkup of our teeth as patients are increasingly screened for medical conditions like heart disease and diabetes. A new study by researchers at Columbia University's Mailman School of Public Health focuses on dental screenings for drug misuse, finding 77 percent of dentists ask patients about illicit drug use, and 54 percent of dentists believe that such screenings should be their responsibility. Results of the study are online in the journal Addiction.
	Sequestered prion protein takes the good mood away, suggests new hypothesis on depression The discovery of antidepressant drugs in the 1950s led to the first biochemical hypothesis of depression, known as the monoamine hypothesis. This hypothesis proposes that an imbalance of certain brain chemicals is the key cause of depression. Research has investigated whether and to what degree the "reward and pleasure" chemical dopamine and, more recently, the "happiness" chemical serotonin, could be the neurotransmitters involved in the malady. However, the monoamine hypothesis does not seem to fully explain the complexity of human depression. Now a new study offers one more important key that may increase our understanding of the pathogenesis behind clinical depression and neurodegenerative disorders.
Gestational diabetes: A diabetes predictor in fathers Gestational diabetes, a type of diabetes that occurs during pregnancy, affects between three and 20 per cent of pregnant women. Those who develop gestational diabetes are 7 times as likely to eventually develop type 2 diabetes in the years following pregnancy. Now, in a large study analyzing 20 years of data from Quebec, a team from the Research Institute of the McGill University Health Centre (RI-MUHC) has demonstrated that gestational diabetes signals future diabetes risk not only in mothers, but also in fathers. The study was recently published in Diabetes Care.
Transplant recipients more likely to develop aggressive melanoma Organ transplant recipients are twice as likely to develop melanoma as people who do not undergo a transplant, and three times more likely to die of the dangerous skin cancer, suggests new research led by a Johns Hopkins Bloomberg School of Public Health student.
Surgeons refine procedure for life-threatening congenital heart defect For children born with life-threating hypoplastic left heart syndrome (HLHS), reconstructive surgeries can restore blood circulation. While the most common corrective approach is the three-stage Norwood procedure, an alternative strategy, hybrid palliation, allows deferral of the more complex reconstructions to when the child is somewhat older and better able to successfully recover from major surgery. A report in The Journal of Thoracic and Cardiovascular Surgery, the official publication of the American Association for Thoracic Surgery (AATS), evaluates whether an arterial shunt in the hybrid palliation may be a better source for the pulmonary blood supply than the more frequently used venous shunt.
	Heavy smokers and smokers who are obese gain more weight after quitting For smokers, the number of cigarettes smoked per day and current body mass index are predictive of changes in weight after quitting smoking, according to researchers at Penn State College of Medicine.
Study: What gets said should be what's heard; what gets heard should be what's meant The poor exchange of information at change of shift is one of the most common causes of medical errors at hospitals across the country. These errors have been estimated by the Institute of Medicine to cause as many as 98,000 preventable deaths annually.
	Ebola could be defeated by year's end: WHO The Ebola epidemic in West Africa could be completely over by the end of the year if efforts to root out new cases are kept up, the WHO chief said Thursday.
	New information is easier to learn when composed of familiar elements People have more difficulty recalling the string of letters BIC, IAJ, FKI, RSU and SAF than FBI, CIA, JFK, IRS and USA. The well-established reason is that the amount of information we can hold in our short-term or working memory is affected by whether the information can be "chunked" into larger units.
Sex development disorders affect the mind as well as the body While it may not shock you to learn that children born with disorders of sex development (DSD) face challenges, Concordia University researchers have confirmed that these go far beyond the physical.

	US bike deaths fall for kids, but rise for adults (HealthDay)—The rising popularity of bicycling among adult men for pleasure or as a means of commuting may have a downside: More fatal bike-related accidents, according to a new report.
	Pattern of cases, surveillance data similar for lyme disease (HealthDay)—The estimated annual incidence of Lyme disease (LD) is 106.6 cases/100,000 persons in the United States, according to a report published online Aug. 12 in the U.S. Centers for Disease Control and Prevention's Emerging Infectious Diseases.
	More physicians reporting dissatisfaction with EHR systems (HealthDay)—More physicians report being dissatisfied or very dissatisfied with their electronic health record (EHR) system, compared with five years ago, according to a report published by the AmericanEHR Partners and the American Medical Association.
	Intelligent sensor informs you to change a diaper via SMS Diapers could soon come with a sensor that alerts caregivers by SMS when the diapers are soiled. Researchers from the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR have invented an "intelligent continence management system" comprising a thin disposable sensor strip, a compact wireless transmitter, a receiver and software, which has the potential to improve the care of elderly and bedridden patients.
	Disappearing Down syndrome, genetic counseling, and textbook coverage Last week, several people sent me a perspective piece by bioethicist Art Caplan in PLOS Biology, "Chloe's Law: A Powerful Legislative Movement Challenging a Core Ethical Norm of Genetic Testing." The concise and compelling article considers legislation to mandate that genetic counselors talk to their patients more about positive aspects of having a child with trisomy 21 Down syndrome.
	Collective intelligence helps to improve breast cancer diagnosis Breast cancer is the most frequent type of cancer in women and currently accounts for 29% of all new cancer cases in the U.S. Wide-ranging mammography screening programs have been set up for early diagnosis. However, even if two physicians assess the x-rays, which is the usual procedure in Europe, this often leads to wrong decisions: about 20% of patients with cancer are diagnosed as being cancer-free, whereas about 20% of cancer-free patients are diagnosed with cancer. A new study shows that swarm intelligence can help to considerably improve cancer diagnosis.
	Team begins first clinical trial of stem cell-based retinitis pigmentosa treatment Participants are being enrolled in the first clinical trial that tests the use of retinal progenitor cells to treat retinitis pigmentosa, reported project director Dr. Henry Klassen of UCI's Gavin Herbert Eye Institute and Sue & Bill Gross Stem Cell Research Center. The product of stem cell research at UCI, these retinal progenitors are similar to stem cells in terms of potential regenerative properties, but they're specific to the retina.

	Millionaires are more generous in 'communal' interactions than 'strategic' exchanges (Phys.org)—The current economic climate of massive inequality coupled with a global trend toward painful austerity in government spending has fostered a renaissance of philanthropic giving that is unprecedented in history. It is likely that for at least the next 30 years, philanthropic giving by high net-worth individuals (HNWIs) and their foundations will be the biggest driver of social change around the world.
	Human language may have started differently than thought (Phys.org)—A trio of researchers, two with the University of Wisconsin, the other with the University of California, has conducted a study, the results of which suggest that maybe humans did not get a start on language using only hand gestures as many scientists have theorized. Instead, as Marcus Perlman, Rick Dale and Gary Lupyan note in their paper published in Royal Society Open Science, it may have been a result of both noise-making and gesturing.
	Grammar: Eventually the brain opts for the easy route Languages are constantly evolving—and grammar is no exception. The way in which the brain processes language triggers adjustments. If the brain has to exert itself too much to cope with difficult case constructions, it usually simplifies them over time, as linguists from the University of Zurich demonstrate in a study on languages all over the world.
	Documents reveal price of Britain's slave trade Letters discussing the value and sale of slaves in the 18th century, which provide a distressing reminder of the powerful business interests that sustained one of the darkest chapters in British history, are to be made available to researchers and the public by St John's College, University of Cambridge.
	New clues to the fate of America's Lost Colony Archaeologists from the University of Bristol have uncovered artefacts that they believe may help solve the long-running mystery of the fate of the first English colonists in North America. Excavations on the Island of Hatteras (North Carolina) have discovered a number of artefacts, dated to late 16th century, which point to the possibility that the colonists assimilated into the local Native American tribe. It is hoped these early findings could solve one of America's greatest historical mysteries.
	Study shows driver's ed significantly reduces teen crashes, tickets A new study that followed more than 150,000 teen drivers over eight years has found that driver's education significantly reduces crashes and traffic violations among new drivers.
Could Shakespeare have been high when he penned his plays? State-of-the-art forensic technology from South Africa has been used to try and unravel the mystery of what was smoked in tobacco pipes found in the Stratford-upon-Avon garden of British playwright William Shakespeare.

	Police more likely to be killed on duty in states with high gun ownership Camden and Newark, New Jersey, are perceived as two of the most violent cities in the nation, yet New Jersey's police officers are among the least likely to get shot on the job. Montana, with its serene landscapes and national parks, has among the highest homicide rates for law enforcement officers. Why?
	High participation in small church groups has its downside, research shows Parishioners who participate in small groups within a religious congregation are generally more likely to be civically engaged than their fellow worshipers unless a church has high overall small-group participation, according to research recently released by Clemson and Louisiana State universities.
	Citizen science in New Mexico Time traveling is one of my favorite things to do as a citizen scientist. As part of the New Mexico Site Steward Program, I walk slowly through an archeological site, the ground littered with the remains of pottery from people who lived here a thousand years ago. I am free to touch and finger these clay shards as long as I carefully put them back where I found them. I pick up (and put down) a square of white with thin black lines, part of a bowl with an interior painted scene—perhaps a crane spearing fish or a woman giving birth. I pick up (and put down) a curved piece the size of my palm of brown corrugated cooking ware–all those simmering stews of meat, roots, and herbs. I pick up (and put down) a geometric pattern of red and white, part of the human aesthetic: look at the world in this way.

Setting prices centrally, w/optimization yields higher profits than local pricing A study on granting local sales people pricing discretion shows that profits improve by up to 11% when local sales forces are empowered to negotiate with customers. However a centralized system that uses optimization techniques and limits local sales discretion improves profits still further, by an additional 20%. The research appears in the current issue of Management Science, a publication of the Institute for Operations Research and the Management Sciences (INFORMS), the leading professional association in analytics and operations research.
