Deccan Chronicle: "In a study that has been widely welcomed, researchers from the University of Copenhagen found that eating cheese is good for our hearts." More from [askmen] [delish] [allure] [Telegraph - mentions other studies]. The actual research article conclusion: "A high daily intake of regular-fat cheese for 12 weeks did not alter LDL cholesterol or MetS risk factors differently than an equal intake of reduced-fat cheese or an isocaloric amount of carbohydrate-rich foods."
Maternal kisses are not effective in alleviating minor childhood injuries (boo-boos): a randomized, controlled and blinded study, by the Study of Maternal and Child Kissing (SMACK) Working Group.
José L. Duarte is one author of an upcoming paper in Behavioral and Brain Sciences, "Political Diversity Will Improve Social Psychological Science." The authors review how academic psychology has lost its former political diversity, and explore the negative consequences of this on the field's search for true and valid results. Duarte has blogged about his own experience of bias when he was denied admission to a Ph.D program, possibly for for his perceived political views in another blog post. [more inside]
What it’s like to earn a living as a research subject in clinical trials Today, Stone no longer relies on strangers in bars—instead, he’s a part of a small community that shares info about study opportunities. Stone says he sends mass texts whenever he sees a new study online. In exchange, the group does the same for him. The members of this group call themselves guinea pigs, or lab rats. They also call themselves professionals.
Every day, news sources report on medical studies that describe promising new treatments. Most of them don't pan out in the end. Julia Belluz reports on "why you shouldn’t believe that exciting new medical study." Her article includes a figure showing which foods are reported to cause cancer and which ones are reported to prevent it. (Spoiler: they're the same foods.)

Lovatt reasoned that if she could live with a dolphin around the clock, nurturing its interest in making human-like sounds, like a mother teaching a child to speak, they'd have more success. - stories from the NASA- funded project to teach Dolphins to talk using LSD (among other methods. )

Why You Won’t Be the Person You Expect to Be (NYT): "When we remember our past selves, they seem quite different. We know how much our personalities and tastes have changed over the years. But when we look ahead, somehow we expect ourselves to stay the same... They called this phenomenon the “end of history illusion,” in which people tend to “underestimate how much they will change in the future.”" (via exp.lore) [more inside]
"Experimental adaptation of an influenza H5 HA confers respiratory droplet transmission to a reassortant H5 HA/H1N1 virus in ferrets." After an extensive, months-long debate, one of two controversial papers showing ways the H5N1 "avian" influenza virus could potentially become transmissible in mammals with only 3 or 4 mutations was published in Nature today. The journal included an editorial on the merits and drawbacks of "publishing risky research" with regard to biosafety. The debate included an unprecedented recommendation by The US National Science Advisory Board for Biosecurity (NSABB) to block publication -- a decision they later reversed. (Via: 1, 2) Nature's special report has additional articles, including interviews with the teams behind both papers.
"Researchers at McMaster University have conclusive evidence that bacteria residing in the gut influence brain chemistry and behaviour. [...] To confirm that bacteria can influence behaviour, the researchers colonized germ-free mice with bacteria taken from mice with a different behavioural pattern. They found that when germ-free mice with a genetic background associated with passive behaviour were colonized with bacteria from mice with higher exploratory behaviour, they became more active and daring. Similarly, normally active mice became more passive after receiving bacteria from mice whose genetic background is associated with passive behaviour." [more inside]

The Beer Archaeologist. "Biomolecular archaeologist" Dr. Patrick McGovern has unearthed millennia-old alcohol recipes and ancient medicinals, "by analyzing residues in ancient pottery. Now he's working with brewer Sam Calagione, (of Discovery Channel's Brew Masters, (autoplaying video)) whose pub Dogfish Head serves up beers based on recipes that are thousands of years old."

One in every 8 babies born in the US is premature. A new study (pdf/via) published online Wednesday in Ultrasound in Obstetrics and Gynecology indicates that vaginal progesterone gel can help women who are pregnant for the first time and at risk of premature birth extend their pregnancies, reduce potential complications and boost the health of their newborns.

Epidemiology: Study of a lifetime. "In 1946, scientists started tracking thousands of British children born during one cold March week. On their 65th birthday, the study members find themselves more scientifically valuable than ever before." [more inside]
Invasive amniocentesis and chorionic villi sampling (CVS) tests are commonly used to determine the chromosomal, structural and genetic abnormalities in fetuses. But could they eventually become obsolete? A Chinese study has found that a complete copy of the fetal genome exists in the mother's blood, suggesting many prenatal diagnoses could potentially be performed noninvasively. [more inside]
A nearly 25-year study has concluded that children raised in lesbian households were psychologically well-adjusted and had fewer behavioral problems than their peers.

Science vs. Religion: a new book, Science and Religion: What Scientists Really Think by Rice University sociologist Elaine Ecklund, discusses the results of her detailed study of 1,646 scientists at top American research universities. Among her findings: ~36% of those surveyed not only believe in God but also practice a form of closeted, often non-traditional faith. They worry about how their peers would react to learning about their religious views. Interview with the author from the Center for Inquiry's Point of Inquiry podcast. Also, here's a webcast from an author discussion forum held at Rice University on April 7th. [more inside]
What do Singing in the Rain, Live Is Life, Don't Worry, Be Happy, I Will Survive and Ça fait rire les oiseaux have in common?

"...for the scientific community, the most critical organ of the incentive system is the cycle of credit."
Just how credible is Wikipedia? While some have tested this empirically, others have chosen more dubious methodology. For a site that gives no credit to its post authors, one wonders, why even bother?
High BMI Now Means Cognitive Difficulties Later? A study published in Neurology attempts to discover if there is a link between cognitive function, cognitive decline and BMI (body mass index) over time. Yes, I am aware that BMI is a flawed metric.

Your eyes never stop moving. Even though we are rarely aware of them, our eye movements are incredibly complex. They are also very informative. Eye movement data is being used to study painters painting, art lovers loving art, drivers driving, musicians sight reading, and speakers speaking, not to mention the cognitive science staples of reading and scene viewing. One interesting application of eye movement data is the Eyetrack2000 project, which attempts to describe the eye movement behavior of people viewing news websites in order to improve web page design. Some of the findings suggest that the internet and print media are different in important ways: on the web, text is fixated before pictures; in print, pictures are fixated first.
