	OSIRIS spots Philae drifting across the comet These incredible images show the breathtaking journey of Rosetta's Philae lander as it approached and then rebounded from its first touchdown on Comet 67P/Churyumov–Gerasimenko on 12 November 2014.
	Team creates Milky Way structure simulations If you took a photograph of the Milky Way galaxy today from a distance, the photo would show a spiral galaxy with a bright, central bar (sometimes called a bulge) of dense star populations. The Sun—very difficult to see in your photo—would be located outside this bar near one of the spiral arms composed of stars and interstellar dust. Beyond the visible galaxy would be a dark matter halo—invisible to your camera but important nonetheless because it keeps everything together by dragging down the rotational velocity of the bar and spiral arms.
	NASA image: Saturn's upper cloud layers (Phys.org) —What the viewer might perceive to be Saturn's surface is really just the tops of its uppermost cloud layers. Everything we see is the result of fluid dynamics. Astronomers study Saturn's cloud dynamics in part to test and improve our understanding of fluid flows. Hopefully, what we learn will be useful for understanding our own atmosphere and that of other planetary bodies.
	What Philae did in its 60 hours on Comet 67P The drama of Philae's slow fall, bounce and unfortunate slide into hibernation was one of the most thrilling science stories of a generation. But what in its short 60 hours of life on Comet 67P did it achieve?

	When fighting lung cancer, every cancer is personal Larry Dry's lung cancer was discovered by accident. The husky, physically active 69-year-old had no cough, no breathing problems, only a little tingling in one hand. When his doctor ordered an X-ray before surgery for a pinched nerve, he wasn't thinking lung cancer. Dry hadn't smoked in 40 years and a chest X-ray taken less than a year earlier had been perfectly clear. But the new X-ray contained ghostly images of large nodules. Non-small cell lung cancer. Stage IV, the most advanced kind. Eight months of gut-wrenching chemotherapy shrank the tumors, but they quickly rebounded. A second, less toxic drug didn't work.

A global surge in ADHD diagnosis has more to do with marketing than medicine You can't catch attention deficit hyperactivity disorder (ADHD). Yet the diagnosis and treatment of this behavioral condition is spreading like a contagion—surging as much as tenfold in some countries.
Childhood adversity hinders genetic protection against problem drinking in white men While the influence of heritable factors on the development of alcohol use disorders (AUDs) has been documented in family pedigree and twin studies for decades, identification of specific genetic variants that influence AUDs continues to be challenging. The ADH1B gene has consistently been implicated in problem drinking, but rarely incorporated into gene/environment investigations of alcohol phenotypes. A study examining the joint effects of variation in ADH1B and childhood adversity on heaviness of alcohol consumption and AUD symptoms has found that, under conditions of childhood adversity, the genetic variant on the ADH1B allele that typically protects against problem drinking does not exert its protective effects in European-American men.
Chronic alcohol intake can damage white matter pathways across the entire brain Chronic misuse of alcohol results in measurable damage to the brain. Chronic drinking may be particularly damaging to the integrity of frontal white matter tracts, which can interfere with cognitive and inhibitory control that, in turn, is important to achieve and maintain abstinence. A new study has used high-resolution structural magnetic resonance (MR) scans to determine the brain's regional vulnerability to chronic alcohol abuse, finding that abstinent alcoholics have reductions in white matter pathways across the entire brain.
Youths with a family history of substance use disorders have less efficient forebrain Researchers and clinicians know that youths with a family history of alcohol and other drug use disorders (FH+) have a greater risk of developing substance-use disorders (SUDs) than their peers with no such family histories. This increased risk may be related to impaired maturation of forebrain circuitry. A new study examines forebrain activity in youths with a family history of SUDs, finding they had greater activity in several forebrain regions during a specially designed task than their peers with no such family histories, indicating their forebrain regions function less efficiently.
	Shift in gut bacteria observed in fiber supplement study may offer good news for weight loss Most Americans don't get the daily recommended amount of fiber in their diet, though research has shown that dietary fiber can cause a shift in the gut toward beneficial bacteria, reducing the risk of colon cancer, type 2 diabetes, and other diseases. A new study from the University of Illinois shows that two specific functional fibers may also have the potential to assist in weight loss when made part of a long-term, daily diet.

	Taking antibiotics during pregnancy increases risk for child becoming obese A study just released by Columbia University's Mailman School of Public Health found that children who were exposed to antibiotics in the second or third trimester of pregnancy had a higher risk of childhood obesity at age 7. The research also showed that for mothers who delivered their babies by a Caesarean section, whether elective or non-elective, there was a higher risk for obesity in their offspring. Study findings are published online in the International Journal of Obesity.
	Pain from rejection and physical pain may not be so similar after all Over the last decade, neuroscientists have largely come to believe that physical pain and social pain are processed by the brain in the same way. But a new study led by the University of Colorado shows that the two kinds of pain actually use distinct neural circuits, a finding that could lead to more targeted treatments and a better understanding of how the two kinds of pain interact.
	New data suggest little benefit of adding heart valve repair to bypass surgery in patients with coronary heart disease The addition of mitral valve (MV) repair (a valve of the heart) to coronary artery bypass grafting (CABG), a type of open-heart surgery, did not result in significant benefit to the patient and was associated with increased risk of neurological events. Therefore, the routine addition of MV repair to CABG in patients with moderate IMR did not demonstrate a clinically meaningful advantage.
Why we need to fund newer blood-thinning agents to prevent strokes Care gaps are emerging due to disharmony between healthcare reimbursement policies and evidence-based clinical guideline recommendations, cautions a group of Canadian physicians. Writing in the Canadian Journal of Cardiology, they use the example of stroke prevention in atrial fibrillation (AF) to make a case for engaging with policy-makers to address the growing barriers to patients' access to optimal care.
