	POLARBEAR detects curls in the universe's oldest light (Phys.org) —Cosmologists have made the most sensitive and precise measurements yet of the polarization of the cosmic microwave background.
	POLARBEAR seeks cosmic answers in microwave polarization An international team of physicists has measured a subtle characteristic in the polarization of the cosmic microwave background radiation that will allow them to map the large-scale structure of the universe, determine the masses of neutrinos and perhaps uncover some of the mysteries of dark matter and dark energy.
	Cosmic rays threaten future deep-space astronaut missions Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University of New Hampshire scientists.
	NASA Webb's heart survives deep freeze test After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
	Extreme ultraviolet image of a significant solar flare The sun emitted a significant solar flare on Oct. 19, 2014, peaking at 1:01 a.m. EDT. NASA's Solar Dynamics Observatory, which is always observing the sun, captured this image of the event in extreme ultraviolet wavelength of 131 Angstroms – a wavelength that can see the intense heat of a flare and that is typically colorized in teal.
	New radio telescope ready to probe Whirring back and forth on a turning turret, the white, 40-foot dish evokes the aura of movies such as "Golden Eye" or "Contact," but the University of Arizona team of scientists and engineers that commissioned it earlier this month isn't planning to listen for signals from extraterrestrials or hijack satellites.
	Image: Comet 67P/Churyumov–Gerasimenko It was 45 years ago when astronomer Klim Churyumov and Svetlana Gerasimenko, one of his researchers, unwittingly began a new chapter in the history of space exploration.
	How to safely enjoy the October 23 partial solar eclipse 2014 – a year rich in eclipses. The Moon dutifully slid into Earth's shadow in April and October gifting us with two total lunars. Now it's the Sun's turn. This Thursday October 23 skywatchers across much of the North America and Mexico will witness a partial solar eclipse. From the eastern U.S. the eclipse will reach maximum around the time of sunset, making for dramatic picture-taking opportunities. Further west, the entire eclipse will occur with the sun up in the afternoon sky. Either way, you can't go wrong.
	MAVEN studies passing comet and its effects NASA's newest orbiter at Mars, MAVEN, took precautions to avoid harm from a dust-spewing comet that flew near Mars today and is studying the flyby's effects on the Red Planet's atmosphere.

	Middle-aged adults were more susceptible to the flu last year because of a new viral mutation A team of scientists, led by researchers at The Wistar Institute, has identified a possible explanation for why middle-aged adults were hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season. The findings, published in the Proceedings of the National Academy of Sciences, offer evidence that a new mutation in H1N1 viruses potentially led to more disease in these individuals. Their study suggests that the surveillance community may need to change how they choose viral strains that go into seasonal influenza vaccines, the researchers say.
	Studies suggest participants in group conflicts misunderstand opponent's motives (Medical Xpress)—A trio of researchers, Adam Waytz, Liane Young and Jeremy Ginge, has conducted several studies to better understand why it is that opposing groups find it so difficult to compromise to end a conflict. As they explain in their paper published in Proceedings of the National Academy of Sciences their studies show that not only do members of opposing groups misunderstand their opponents' motives, but their perception can be altered by offering a simple reward.

	Impressions shaped by facial appearance foster biased decisions Research in recent years has shown that people associate specific facial traits with an individual's personality. For instance, people consistently rate faces that appear more feminine or that naturally appear happy as looking more trustworthy. In addition to trustworthiness, people also consistently associate competence, dominance, and friendliness with specific facial traits. According to an article published by Cell Press on October 21st in Trends in Cognitive Sciences, people rely on these subtle and arbitrary facial traits to make important decisions, from voting for a political candidate to convicting a suspect for a crime. Referring to this systemic bias as "face-ism," the authors present its real-world consequences and discuss potential ways of overcoming it.

Study suggests a novel approach for treating non-cardiac chest pain Chest pain doesn't necessarily come from the heart. An estimated 200,000 Americans each year experience non-cardiac chest pain, which in addition to pain can involve painful swallowing, discomfort and anxiety. Non-cardiac chest pain can be frightening for patients and result in visits to the emergency room because the painful symptoms, while often originating in the esophagus, can mimic a heart attack. Current treatment—which includes pain modulators such as selective serotonin reuptake inhibitors (SSRI)—has a partial 40 to 50 percent response rate in alleviating symptoms.

Smoking interferes with neurocognitive recovery during abstinence from alcohol Numerous studies have shown that individuals with an alcohol use disorder perform worse than those without one on multiple neurocognitive domains of function following detoxification from alcohol, although the level of impairment can vary widely among individuals. A new study of the degree of neurocognitive recovery in treatment-seeking alcohol dependent individuals (ALC) – with varied degrees of smoking status – during the first eight months of sustained abstinence from alcohol has found that smoking status influenced the rate and level of recovery.
Bar attendance supports heavy drinking by young adults in the US-Mexico border region Due to a legal drinking age of 18 years, cheaper alcohol, and marketing tactics of local bars that specifically target youth, Mexico is an attractive and geographically nearby destination where younger U.S. residents legally drink heavily. However, levels of drinking on the U.S. side are high even among youth who did not recently travel to Mexico. A new study examined whether two factors typical of risky drinking in Mexico – bar attendance and permissive alcohol-related social-cognitions – might also explain higher drinking on the U.S. side, finding that patterns of bar attendance were strongly linked to higher drinking among U.S. border youth, but liberal social cognitions were not.
Understanding drinking behaviors among women with unwanted pregnancies Most women reduce or stop drinking alcohol upon discovery of pregnancy. However, little information exists about changes in alcohol use, and factors contributing to these changes, among women with unwanted pregnancies. A new study examines changes in alcohol use from before pregnancy recognition to during pregnancy among women with unwanted pregnancies – meaning women who tried, but were unable, to terminate their pregnancies. Findings indicate that most women with unwanted pregnancies quit or reduce alcohol consumption once they discover their pregnancies, and that some may be substituting alcohol for drugs once they discover their pregnancies.

	Ebola: Why virus kills some, other people survive People who shared an apartment with the country's first Ebola patient are emerging from quarantine healthy. And while Thomas Eric Duncan died and two U.S. nurses were infected caring for him, there are successes, too: A nurse infected in Spain has recovered, as have four American aid workers infected in West Africa.

Bogus recycling bins help identify drinking patterns among low-income seniors Substance abuse is the fastest growing health concern for older adults, a segment of the population that is likewise rapidly increasing. Heavy drinking among older persons is associated with an increased risk of health problems like diabetes, cognitive impairment, sleep issues, and depression. A new study has examined drinking patterns among low-income older adults using both self-report and outside-of-the-box methods, finding that drinking levels are high enough to be of concern and tend to spike around the times older adults receive their social security checks.
Studies must be carried out to determine whether exercise slows the onset of type 1 diabetes in children and adults Rates of type 1 diabetes—the autoimmune form of the condition that often begins in childhood and eventually results in lifelong dependency on insulin—are increasing in almost all nations worldwide. However, while it appears possible from research in other forms of diabetes that physical exercise could slow the progression of this disease, there have been no studies to date that explore this in patients with type 1 diabetes. In a paper published in Diabetologia (the journal of the European Association for the Study of Diabetes) researchers argue that such trials must be carried out to potentially benefit the millions of people affected by type 1 diabetes worldwide.
