10:27 PM | Stereotype lowers math performance in women, no one noticed
Stereotypes about people can affect how we look at a person, but sometimes it causes other problems. Gender stereotypes about women’s ability in mathematics negatively impact their performance. And in a significant twist, both men and women wrongly believe those stereotypes will not undermine women’s math performance — but instead motivate them to perform better. […]

6:29 PM | Dark Matter - Now With More Darkness
Dark matter is an umbrella term for matter that no one has directly detected but must be out there or physics at the very large scale makes even less sense than it makes now. Since it does not reflect, absorb or emit light, it is invisible, so whatever it 'is' is only known to exist via its gravitational effects on matter as we know it.read more

6:20 PM | High-fat diet causes brain inflammation and alters behavior
We hear in the media all the time, obesity is effecting our health. In most cases when we talk obesity we are talking about heart disease, sedentary activity, or chronic overeating. But what if a high-fat diet — regardless of obesity — has more than just an affect on your waistline? What if the consumption of fatty […]

5:44 PM | 15 Breeds Of Dog In England Killed By Mystery Kidney Disease 
At least 30 dogs in England have been killed in less than 18 months by an unknown disease which causes skin lesions and kidney failure, reveals research published in Veterinary Record. The disease is believed to be Alabama rot (cutaneous and renal glomerular vasculopathy), a condition which has been seen in the USA in greyhounds for almost 30 years. While there have been occasional reports of the disease in individual dogs outside of the USA, this is the first report of a series of cases […]

5:43 PM | Got Fresh Milk? Now You Do, Without Being On The Grid
Milk is a key element for household food security and provides a stable income to farmers including women, who are usually in charge of taking care of the milk-producing animals in the low-income countries. Currently pathogen growth in milk is managed with refrigeration or with chemicals. Although bacterial growth in milk is managed with refrigeration in the high-income countries, a high cost of infrastructure and a demand for a permanent electricity supply prevent milk refrigeration in the […]

4:39 PM | The Mediterranean Diet Will Reduce Global Warming
The Mediterranean diet became a health fad when epidemiologists looked at a region in Europe and determined that their lower heart disease was due to more fish.A new paper uses a debunked claim "it takes a gallon of gas to make a pound of beef" and uses that to declare that a new diet would reduce global warming. The authors from the University Hospital Complex of Huelva, Jaume I University of Castellón and the University of Huelva compared the daily menus in Spain, based […]

3:28 PM | Neuroskeptic On Bloggingheads
Over at Bloggingheads.tv, I've been interviewed by John Horgan, science journalist and author of books such as The Undiscovered Mind. We talked about whether neuroscience will be able to help diagnose mental illness; why we need to reform how science is published; the mess that is the Human Brain Project; and on a more personal note, about why I became a neuroscientist and why I blog pseudonymously as "Neuroskeptic".

2:30 PM | Goldilocks Scaling - How Organisms Know Just The Right Size
Animal development has an intriguing puzzle - scaling, the proportionality of different body parts. Whether you have an elephant or a mouse, organ and tissue sizes are generally proportional to the overall size of the body.Clearly evolution determined 'just right' but how? Some new clues from fruit flies show the size and patterning accuracy of an embryo depend on the amount of reproductive resources mothers invest in the process before an egg leaves the ovary.read more

2:17 PM | When Is It Dementia Rather Than Just Old Age?
As we age, our bodies biologically are going to perform less efficiently. There are no 60-year-old shortstops in major league baseball, we can injure more easily and our brains slow down as well. We often won't have the memory or cognitive processing ability we used to have, but that doesn't mean it is dementia.A new paper outlines a risk factor scoring system for dementia. The downside to risk factors is people really do not understand them, if Angelina Jolie continues to get genetic tests and […]

1:30 PM | Orthorexia Nervosa: The Righteous Health Food Obsession
Orthorexia nervosa, the “health food eating disorder”, gets its name from the Greek word ortho, meaning straight, proper or correct. This exaggerated focus on food can be seen today in some people who follow lifestyle movements such as “raw”, “clean” and “paleo”.American doctor Steven Bratman coined the term “orthorexia nervosa” in 1997 some time after his experience in a commune in upstate New York. It was there he developed an […]

1:00 PM | Will New Antibiotics Reduce The Resistance Problem?
Most savvy citizens and policy makers are concerned about the departure of the world's best and brightest researchers from antibiotic discovery - regulations are up and everyone wants generic prices from the moment products are approved - but a paper in BMJ takes the contrarian approach and argues new antibiotics probably wouldn't help with antibiotic resistance anyway.Associate Editor and Assistant Professor at the University of Maryland School of Pharmacy Peter Doshi, like many […]

12:08 PM | Fox News, the NFL, and Concussion Denial
I have been a fan of professional football since my college days (go Pats) but I also recognize that it is a brutal sport prone to injuries. In recent years awareness of the true neurological risk of concussions, especially repeated concussions, has been increasingly coming to light. This may cause some cognitive dissonance among fans, [...]

9:14 AM | 10 tortuous psychology studies you'll be glad you didn't participate in
Many psychology studies involve nothing more challenging for participants than sitting down with a short paper questionnaire and ticking off agreement or not with a series of anodyne statements. This post is not about that kind of research. Here, we take a tour of some rather more arduous and quirky experiments from the psychology archives. Participants in these studies were prodded, embarrassed, disgusted, scared, teased, bored and more (though not at once). It was all in the name of science, […]

8:00 AM | How Safe Is Air Travel?
In light of the news of another tragic airline crash, and following in the wake of several other high profile air disasters, it might be natural to ask whether air travel is becoming less safe.In fact, according to the numbers, air travel is safer than at almost any point in the history of commercial flight.While the number of fatalities in some recent crashes has been high, the number of overall fatal accidents in recent years has dropped to its lowest point since the dawn of the jet age.

6:05 AM | A Tampon Could Help Predict Endometrial Cancer
A new study finds that it is possible to detect endometrial cancer using tumor DNA picked up by ordinary tampons. DNA samples from vaginal secretions can show the presence of chemical "off" switches - known as methylation - that can disable genes that normally keep cancer in check. The finding is a critical step toward a convenient and effective screening test for endometrial cancer, which is the most common gynecologic malignancy in the United States. read more

2:21 AM | Kurgan Hypothesis: Origins Of Indo-European Languages
"Ancestry-constrained phylogenetic analysis supports the Indo-European steppe hypothesis", by Will Chang, Chundra Cathcart, David Hall and Andrew Garrett (all of UC-Berkeley), provides new support for the "steppe hypothesis" or "Kurgan hypothesis", which proposes that Indo-European languages first spread with cultural developments in animal husbandry around 4500 - 3500 BCE. Chang et al. examined over 200 sets of words from living and historical Indo-European languages. After determining how […]

2:21 AM | Pigs Do Just As Well With Corn-ethanol Co-product As With Corn-soybean Meal Diet
Distillers dried grains with solubles, or DDGS, are increasingly common in swine diets in the United States. In recent years, different types of DDGS have come on the market. "Ethanol plants use different procedures to produce DDGS, which results in different end products," said Hans H. Stein, a professor of animal sciences at University of Illinois. "To produce conventional DDGS, the corn is cooked to gelatinize starch prior to fermentation. However, uncooked DDGS can also be used if […]

11:47 PM | CareJack Orthopedic Prosthesis Is A Fancy Name For A Cool Power Vest
Millions of people injure themselves each year lifting physically demanding things, with (insert absurd number here) of dollars in lost productivity, etc., etc.Okay, enough of that, here is the fun part: Some day a cute 105 pound nurse may be able to lift your fat keester into a hospital bed after you injure yourself lifting heavy things incorrectly, and you will be able to thank 'soft' robotics.(1) Which is another way of saying that she might be wearing a power vest that gives her super […]

9:16 PM | Pride Before a Fall: The Intertwining of Pride and Shame in Eating Disorders
Is there a link between eating disorders and shame? What about pride? Can understanding these emotions help us to understand how eating disorders develop, and how they are maintained? In reviewing literature for my specialization paper, I stumbled upon a qualitative study by Skarderud (2007) about the role of shame in eating disorders. I found the article quite interesting, so I fired up the “where was this cited” tool on my university library database and uncovered a wealth of […]

9:01 PM | Common Respiratory Infection Bacteria On Verge Of Becoming Superbugs
Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infection, according to new research.A recent study shows that two genes that confer resistance against a particularly strong class of antibiotics can be shared easily among a family of bacteria responsible for a significant portion of hospital-associated infections. Drug-resistant germs in the same family of bacteria recently infected several patients at two Los Angeles hospitals. […]
