Use asteroids as stepping stones to Mars: Richard Binzel on NASA's asteroid redirect mission

By the end of this decade, NASA hopes to lasso a space rock: The space agency is actively pursuing proposals for its Asteroid Redirect Mission (ARM)—a mission that aims to identify, capture, and redirect an asteroid into lunar orbit. Astronauts might then visit the rock to collect and bring back samples—pieces that would presumably hold remnants of the early solar system. ARM has been touted as a steppingstone toward the ultimate goal of sending humans to Mars: The mission would advance technologies and spaceflight experience needed for humans to colonize the Red Planet.

Planetary atmospheres a key to assessing possibilities for life

A planetary atmosphere is a delicate thing. On Earth, we are familiar with the ozone hole—a tear in our upper atmosphere caused by human-created chemicals that thin away the ozone. Threats to an atmosphere, however, can also come from natural causes.

A low-density planet that won't stick to a schedule

Asteroid Apophis could experience landslides when it passes near Earth

(Phys.org) —A team of space scientists with members from the U.S., China and France has found via computer modeling that an asteroid due to pass close to Earth in 2029 is likely to experience minor landslides. In their paper published in the journal Icarus, the researchers describe the data they input into their model and what the simulation showed.

When did galaxies settle down?

Astronomers have long sought to understand exactly how the universe evolved from its earliest history to the cosmos we see around us in the present day. In particular, the way that galaxies form and develop is still a matter for debate. Now a group of researchers have used the collective efforts of the hundreds of thousands of people that volunteer for the Galaxy Zoo project to shed some light on this problem. They find that galaxies may have settled into their current form some two billion years earlier than previously thought.

Cassini sees sunny seas on Titan

(Phys.org) —As it soared past Saturn's large moon Titan recently, NASA's Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas.

Hubble sees 'ghost light' from dead galaxies

(Phys.org) —NASA's Hubble Space Telescope has picked up the faint, ghostly glow of stars ejected from ancient galaxies that were gravitationally ripped apart several billion years ago. The mayhem happened 4 billion light-years away, inside an immense collection of nearly 500 galaxies nicknamed "Pandora's Cluster," also known as Abell 2744.

Men who perform "mate guarding" behaviours such as staying close to their wife or girlfriend at a party are likely to have poorer-quality sperm than men who do not, research suggests.

Neuroscience: Why scratching makes you itch more

Turns out your mom was right: Scratching an itch only makes it worse. New research from scientists at Washington University School of Medicine in St. Louis indicates that scratching causes the brain to release serotonin, which intensifies the itch sensation.

Rewiring cell metabolism slows colorectal cancer growth

Cancer is an unwanted experiment in progress. As the disease advances, tumor cells accumulate mutations, eventually arriving at ones that give them the insidious power to grow uncontrollably and spread. Distinguishing drivers of cancer from benign mutations open opportunities for developing targeted cancer therapies.

Hygienic funerals, better protection for health workers offer best chance to stop Ebola

Hygienic funeral practices, case isolation, contact tracing with quarantines, and better protection for health care workers are the keys to stopping the Ebola epidemic that continues to expand in West Africa, researchers said today in a new report in the journal Science.

Link seen between seizures and migraines in the brain

Seizures and migraines have always been considered separate physiological events in the brain, but now a team of engineers and neuroscientists looking at the brain from a physics viewpoint discovered a link between these and related phenomena.

Expectant mothers with epilepsy face tough choices over their medication

A new study published today in The Cochrane Library, highlights the difficult decisions women with epilepsy have to face when they become pregnant. Taking certain drugs used to control epilepsy during pregnancy may be linked to developmental problems in children. The authors of the study say evidence on the safety of anti-epileptic drugs is limited and that more research is needed to ensure women and their doctors make the most informed choices.

Air quality and unconventional oil and gas sites

Research suggesting air pollutants released by unconventional oil and gas production are well over recommended levels in the US is published today in the open access journal Environmental Health. High levels of benzene, hydrogen sulfide and formaldehyde were found. The study is the first to be based on community sampling by people who live near production sites and could be used to supplement official air-quality monitoring programs.

The 'ultimate' stem cell

In the earliest moments of a mammal's life, the developing ball of cells formed shortly after fertilisation 'does as mother says' – it follows a course that has been pre-programmed in the egg by the mother. Extraordinary as this is, what happens then is even more remarkable.

A new tool in drug overdose prevention

The Center for Disease Control reported earlier this month that the heroin overdose death rate across 28 states it surveyed doubled between 2010 and 2012. This sharp increase and the chilling statistics that say more than 110 Americans die each day of heroin and prescription opioid overdose are among the reasons law enforcement and public health officials are trying to find new ways to work together to stem the tide of fatalities.

Obesity prevention programs can help improve blood lipids in kids

A federally-funded systematic review and meta-analysis of 17 childhood obesity prevention programs (with 20 discrete interventions) in high-income countries has found:

Public need better information about screening, say MPs

People are not always provided with sufficient information about the risks of screening for chronic diseases such as cancer, according to an influential group of MPs.

Researchers decipher the role of nanostructures around brain cells in central nervous system function

An accumulation of a protein called amyloid-beta into large insoluble deposits called plaques is known to cause Alzheimer's disease. One aspect of this illness that has not received much attention is which role the structure of the brain environment plays. How do macromolecules and macromolecular assemblies, such as polysaccharides, influence cell interaction in the brain?

Google data could improve forecasting of influenza levels

Clock gene dysregulation may explain overactive bladder

If you think sleep problems and bladder problems are a fact of life in old age, you may be right. A new report appearing in the November 2014 issue of The FASEB Journal, shows that our sleep-wake cycles are genetically connected to our bladder, and disruptions to one may cause problems with the other. This discovery builds on the hypotheses that under normal circumstances, a primary clock located in the brain controls several other peripheral clocks located throughout the body. These peripheral clocks, in turn, control the activity of functional proteins and receptors, including those in the bladder.

New molecule sneaks medicines across the blood/brain barrier

Delivering life-saving drugs across the blood-brain barrier (BBB) might become a little easier thanks to a new report published in the November 2014 issue of The FASEB Journal. In the report, scientists describe an antibody, called "FC5," is one-tenth the size of a traditional antibody and able to cross the BBB. Moreover, FC5 uses the same pathways as nutrients that the brain needs to survive, allowing it to "smuggle" larger antibodies across the barrier. Like a Lego building block, FC5 connects into many types of antibody designs, helping them reach their disease targets in the brain. This research could lead the way for the development of new therapies to fight a wide range of brain diseases, such as Alzheimer's, Parkinson's, cancer, epilepsy, genetic brain diseases, neurodegenerative disease, chronic neuropathic pain, and other conditions.

BPA exposure by infants may increase later risk of food intolerance

If it seems like more people are allergic to, or intolerant of, more and different kinds of foods than ever before, there might be a reason why. A new research published in November 2014 issue of The FASEB Journal, scientists show, for the first time, that there is a link between perinatal exposure to Bisphenol A (BPA) at low doses and the risk to develop food intolerance in later life. This research involving rats suggests that early life exposure at a dose significantly below the current human safety limit set by the FDA affects developing immune systems, predisposing offspring to food intolerance in adulthood.

Size matters: Baby's size at birth may predict risk for disease later in life

A new research report published in the November 2014 issue of The FASEB Journal suggests that being overweight might be better in the long term than being underweight. Before you reach for that box of Twinkies, however, it's important to note that this discovery only applies to the weight of newborn babies in relation to risk of future disease.

Can parents make their kids smarter?

Reading bedtime stories, engaging in conversation and eating nightly dinners together are all positive ways in which parents interact with their children, but according to new research, none of these actions have any detectable influence on children's intelligence later in life.

Researchers find bat influenza viruses unlikely threaten human health

Bats seen at Halloween this year may not be quite as scary as they appear – at least when it comes to the spread of specific viruses. A research project conducted in part by a team of researchers in the College of Veterinary Medicine at Kansas State University suggests that influenza viruses carried by bats pose a low risk to humans.

US sues Gerber over claims on infant formula

U.S. government regulators announced Thursday they were suing Gerber, the well-known baby food maker, for claiming that its Good Start Gentle formula can prevent or reduce allergies in children.

Sadness lasts longer than other emotions

Why is it that you can feel sad up to 240 times longer than you do feeling ashamed, surprised, irritated or even bored? It's because sadness often goes hand in hand with events of greater impact such as death or accidents. You need more time to mull over and cope with what happened to fully comprehend it, say Philippe Verduyn and Saskia Lavrijsen of the University of Leuven in Belgium. Their research, published in Springer's journal Motivation and Emotion, is the first to provide clear evidence to explain why some emotions last a longer time than others.

Breakdown in gut barriers to bacteria may promote inflammation and craving in alcoholics

Bacteria in the gastrointestinal tract fulfill many vital functions and are critical for digestion. Yet, these same bacteria can induce strong inflammatory responses by the immune system if they penetrate the gut and enter the bloodstream.

Could daylight savings time be a risk to diabetics?

Soon, many will turn back the hands of time as part of the twice-annual ritual of daylight savings time. That means remembering to change the alarm clock next to the bed, which will mean an extra hour of sleep before getting up in the morning.

Toddlers copy their peers to fit in, but apes don't

From the playground to the board room, people often follow, or conform, to the behavior of those around them as a way of fitting in. New research shows that this behavioral conformity appears early in human children, but isn't evidenced by apes like chimpanzees and orangutans.

Molecular tumor markers could reveal new therapeutic targets for lung cancer treatment

Analysis of 607 small cell lung cancer (SCLC) lung tumors and neuroendocrine tumors (NET) identified common molecular markers among both groups that could reveal new therapeutic targets for patients with similar types of lung cancer, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology. The Symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung Cancer (IASLC) and The University of Chicago Medicine.

What do American babies eat? A lot depends on Mom's socioeconomic background

How 'trained immunity' mediates BCG therapy of bladder cancer

Bacillus Calmette-Guerin (BCG) is a vaccine widely used in low and middle-income countries to protect against childhood tuberculosis. Besides its specific anti-tuberculosis effects, BCG can also function as a general immune-booster, and in this capacity is used in the treatment of certain bladder cancers. A study published on October 30th in PLOS Pathogens now reports that autophagy (the removal and degradation of unnecessary or dysfunctional components within cells) plays a central role in mediating the non-specific immune effects of BCG.

Navigation and location can occur without external cues

New optimal screening threshold for gestational diabetes in twin pregnancies

A common complication, gestational diabetes affects approximately 6-7% of pregnant women. Currently, screening is done in two steps to help identify patients most at risk; however, the suggested levels for additional testing were based on singleton pregnancy data. Now investigators have analyzed data from twin pregnancies and have determined that the optimal first step cutoff for additional screening appears to be a blood sugar level equal to or greater than 135 mg/dL for women carrying twins. Their findings are published in the American Journal of Obstetrics & Gynecology.

Novel tinnitus therapy helps patients cope with phantom noise

Model explains why HIV prevention dosing differs by sex

A mathematical model developed by NIH grantees predicts that women must take the antiretroviral medication Truvada daily to prevent HIV infection via vaginal sex, whereas just two doses per week can protect men from HIV infection via anal sex. This finding helps explain why two large clinical trials testing HIV pre-exposure prophylaxis, or PrEP, in women failed to show efficacy. Participants in the VOICE and FEM-PrEP trials of Truvada and tenofovir (another antiretroviral) for HIV prevention were counseled to take one of the medications daily. However, because they actually took the antiretroviral only about 29 percent of the time in VOICE and about 36 percent of the time in FEM-PrEP, the PrEP strategy did not work.

The study was conducted by researchers from the Institute for Aging Research (IFAR) at Hebrew SeniorLife, Beth Israel Deaconess Medical Center, the Wyss Institute for Biologically Inspired Engineering at Harvard University, and Harvard Medical School, all of Boston, Massachusetts; and Merck Sharpe and Dohme (MSD) Consumer Care, Inc., of Memphis, Tennessee.
