10:30 AM | Virtual Steak: Beef Is 10X More Environmentally Costly Than Other Meat, Says Study
Easy metrics like 'it takes a gallon of gas to make a pound of beef' or 'it takes 140 liters of water to make a cup of coffee' get mainstream media because they are outrageous. They are outrageous because they are completely wrong. What is the 'real' cost of eating beef? Are the other animal or animal-derived foods better or worse? read more

8:39 AM | Study of dynamic facial expressions suggests there are four basic emotions, not six
New research suggests that humans recognise facial emotional expressions in a dynamic way. We search for urgent signals first, before seeking out more nuanced information. The University of Glasgow researchers also argue their data show there are four basic facial expressions of emotion rather than the widely accepted six.Rachael Jack and her colleagues developed computerised 3-D faces that began neutral and relaxed before transforming over one second into a random expression, created through a […]

8:00 AM | Mammoth And Mastodon Weren't So Nomadic
Mammoths and mastodons, the famously fuzzy relatives of elephants that lived in the American midwest, weren't as nomadic as previously believed – or Cincinnati was just a great place to be at the end of the last ice age. A study led by Brooke Crowley, an assistant professor of geology and anthropology at the University of  Cincinnati, shows the ancient proboscideans enjoyed the area so much they likely were year-round residents and not nomadic migrants as previously […]

7:00 AM | Natural Fluctuation: Global Warming 'Pause' Since 1998 Explained
Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research by McGill University physics professor Shaun Lovejoy. In a new paper, Lovejoy concludes that a natural cooling fluctuation during this period largely masked the warming effects of a continued increase in man-made emissions of carbon dioxide and other greenhouse gases.  read mor

5:44 AM | 100 Locations In Human Genome Associated With Schizophrenia
Researchers have helped identify over 100 locations in the human genome associated with the risk of developing schizophrenia, in what is the largest genomic study published on any psychiatric disorder to date. The findings point to biological mechanisms and pathways that may underlie schizophrenia, and could lead to new approaches to treating the disorder, which hasn't made much scientific progress in the last 60 years. read more

1:31 AM | Hunting For the Marijuana-Dopamine Connection
Why do heavy pot smokers show a blunted reaction to stimulants?Most drugs of abuse increase dopamine transmission in the brain, and indeed, this is thought to be the basic neural mechanism underlying the rewarding effects of addictive drugs. But in the case of marijuana, the dopamine connection is not so clear-cut. Evidence has been found both for and against the notion of increases in dopamine signaling during marijuana intoxication. Marijuana has always been the odd duck in the pond, […]

9:00 PM | Age-Related Macular Degeneration Occurs Much Earlier Than Assumed
Age-related macular degeneration (AMD) is the most common cause of visual impairment and blindness in industrialized countries but it is questionable whether it can continue to be defined as a disease in people in their 50s and beyond. Investigations to determine the incidence of age-related macular degeneration undertaken as part of the Gutenberg Health Study of the University Medical Center of Johannes Gutenberg University Mainz (JGU) have shown that even persons under the age of 50 years […]

8:00 PM | Less Random Fitness: A Refined Biological Evolution Model
Models for the evolution of life are now being developed to try and clarify the long term dynamics of an evolving system of species. Specifically, a recent model proposed by Petri Kärenlampi from the University of Eastern Finland in Joensuu accounts for species interactions with various degrees of symmetry, connectivity, and species abundance. This is an improvement on previous, simpler models, which apply random fitness levels to species. The findings demonstrate that the resulting […]

6:31 PM | Dance Of The Dwarfs
A new discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees but instead 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved.    The universe contains billions of galaxies. Some, such as the Milky Way, are immense, containing hundreds of billions of stars. Most galaxies, however, are dwarfs, much smaller and with only a few billion stars. For decades astronomers have used […]

6:00 PM | Utilizing Fat's Healing Properties In Heart Disease
Too much dietary fat is bad for the heart, everyone knows that by now, but not all fats are equal. The right kind of fat keeps the heart healthy, and a paper in The Journal of Experimental Medicine shows how it works. Unlike saturated fats discussed in popular media, unsaturated dietary fatty acids, such as eicosapentaenoic acid (EPA), are known to protect against cardiovascular diseases. However, the mechanism and the specific fat metabolites responsible for this protection were

4:18 PM | Mapping Environmental Effects On DNA One Cell At A Time
A new single-cell technique can help investigate how the environment affects our development and the traits we inherit from our parents. It can be used to map all of the 'epigenetic marks' on the DNA within a single cell,which will boost understanding of embryonic development, enhance clinical applications like cancer therapy and even reduce the number of mice used in research.read more

3:59 PM | Do “I” exist?
I think therefore I am; or rather, I am currently thinking, therefore I currently am. But where does the “I” come from? Much has been made of clinical cases where the self seems to malfunction spectacularly: like Cotard syndrome, whose victims believe they do not exist, even though they admit to having a life history; or […]

2:48 PM | Delayed Language More Nature Than Nurture
"She'll grow out of it," used to be a common phrase about raising kids, meaning it wasn't anything that was wrong physically or in upbringing, it is just the diversity of human existence. Some kids develop later. But in today's hyper-diagnosis culture, researchers have wanted to figure out if that old saying was true, or just wishful thinking. A  study of 473 sets of twins followed since birth has found that, compared to single-born children, 47 percent of 24-month-old identical twins had […]

1:53 PM | Mitochondria And Antioxidants: A Tale Of Two Scientists
There is a little miracle of science happening in your body right now. As you read this, a minuscule 5 grams of a high-energy molecule called adenosine triphosphate - ATP - is causing all kinds of reactions in order to give you the energy to sit at your computer. In total, 8 ounces of ATP is being recycled hundreds of times each day, so many times that a human can use their body weight - 200 pounds of ATP in my case – every 24 hours.  read more

1:46 PM | oh BOLD where art thou? Evidence for a “mm-scale” match between intracortical and fMRI measures.
A frequently discussed problem with functional magnetic resonance imaging is that we don’t really understand how the hemodynamic ‘activations’ measured by the technique relate to actual neuronal phenomenon. This is because fMRI measures the Blood-Oxygenation-Level Dependent (BOLD) signal, a complex vascular response to neuronal activity. As such, neuroscientists can easily get worried about all sorts of non-neural contributions […]

11:32 AM | You Don't Stop Learning To Read In 4th Grade - Study
Teaching remains more art than science and a popular conjecture that has caught the attention of the education business has been that fourth grade is when students stop learning to read and start reading to learn.  People love to swap terms around that way. But is it accurate? A new paper in Developmental Science says there is nothing special about fourth grade at all, there is no change in automatic word processing, a crucial component of that reading shift conjecture. Instead, […]
