We're bombarded with information at all times, so much that if we had to try and process it all times, we'd be paralyzed. Our cerebellum does information damage control by filtering out what changes. Evolution made it possible for us to conserve energy while still processing anomalies quickly.
Planetary scientists would be thrilled if they could peel the Earth like an orange and look at what lies beneath the thin crust. We live on the planet's cold surface, but the Earth is a solid body and the surface is continually deformed, split, wrinkled and ruptured by the roiling of warmer layers beneath it.
The contrast between the surface and the depth is nowhere starker -- or more important -- than in Antarctica. What is causing the mysterious line of volcanoes that emerge from the ice sheet there, and what does it mean for the future of the ice?
Boston, MA - Although no reliable official data currently exist on the number of law enforcement-related deaths each year in the U.S., counting these deaths can and should be done because the data constitute crucial public health information that could help prevent future deaths, according to a new study from Harvard T.H. Chan School of Public Health.
Measuring the levels of RNA biomarkers in blood may help quickly differentiate sepsis from infection-negative systemic inflammation, according to research published this week in PLOS Medicine. Leo McHugh, Ph.D. of Immunexpress, Seattle, Washington, and colleagues describe the discovery and validation of a molecular classifier consisting of 4 RNA transcripts (SeptiCyte Lab), which in several selected patient cohorts was able to diagnose sepsis more accurately than procalcitonin or clinical parameters, and more quickly than blood culture.
MADISON, Wis. -- Starting around 1950, a series of advances formed a clear and accepted picture of how individual stars are born, evolve and die. As they age, the changing patterns of color, light output, size and lifespan of stars are predictable. Every star like the sun will become a red giant, a planetary nebula and finally a white dwarf.
But half of all stars are in binaries -- pairs of stars that orbit each other. Half of binary stars orbit so close that gravitational interaction significantly affects their evolution and demise. Today, scientists led by Robert Mathieu, a professor of astronomy at the University of Wisconsin-Madison, and his former student Natalie Gosnell confirmed one of the possible explanations for a common group of exceptions: the blue stragglers.
'Delay discounting' is the tendency, given the choice, to take a smaller reward that is available immediately, instead of a larger reward that will be delivered in the future - and that is a trait that can be inherited.
Yes, your impulsive nature can be blamed on your parents, according to a report presented today at the American College of Neuropsychopharmacology annual meeting. If you need an excuse for spending too much on things you don't need, just say your delay discounting is in your genetic makeup.
Porcine Reproductive and Respiratory Syndrome (PRRS) virus, first detected in the U.S. in 1987, has been identified as a $660 million per year problem. Pigs who contract the disease have extreme difficulty reproducing, don't gain weight and have a high mortality rate and no vaccine has been effective.
A team of researchers from the University of Missouri, Kansas State University, and Genus plc have put biology on the case, by breeding genetically edited pigs that are not harmed by the disease.
Boston, MA - Diacetyl, a flavoring chemical linked to cases of severe respiratory disease, was found in more than 75% of flavored electronic cigarettes and refill liquids tested by researchers at Harvard T.H. Chan School of Public Health. Two other potentially harmful related compounds were also found in many of the tested flavors, which included varieties with potential appeal to young people such as Cotton Candy, Fruit Squirts, and Cupcake.
The study will be published online December 8, 2015 in Environmental Health Perspectives and will be available here after the embargo lifts: http://ehp.niehs.nih.gov/15-10185.
Children born to mothers with polycystic ovarian syndrome, PCOS, are at an increased risk of developing autism spectrum disorders, according to a new epidemiological study from Sweden's Karolinska Institutet. The findings, which are published in the journal Molecular Psychiatry, support the notion that exposure to sex hormones early in life may be important for the development of autism in both sexes.
Though 99.9999% of species that have gone extinct have never actually been identified, it is common to read claims that we are facing a catastrophic species extinction crisis.
It's best to take such talk with a grain of salt, because conservationists are only now discovering that cities are better at preserving species than pristine wilderness environments. A recent study looked at the distributions of 1,643 protected species in Australia, and counted up the number of these species that occurred in square-kilometer units across the continent. They found that, on average, urban environments contain more threatened protected species in a given area than rural environments.
Add green tea to the growing list of substances that activists will soon be calling an endocrine disruptor; a study has found that, rather than bring health benefits, as Big Tea proclaims, excessive consumption adversely affects development and reproduction in fruit fly populations.
Derived from the plant Camellia sinensis, green tea is popular worldwide for its purported brain and heart health and anticancer properties.
Nutraceuticals such as green tea, are popular among groups that distrust agricultural, medical, and energy science, but they are unregulated.
A team of psychologists say MIT linguist Noam Chomsky's discredited belief that we possess an "internal grammar" that allows us to comprehend even nonsensical phrases holds up.
PHILADELPHIA, December 7, 2015 - The leading cause of epilepsy-related death is a poorly understood phenomenon known as sudden unexpected death in epilepsy (SUDEP). The risk factors and causes of SUDEP remain unclear but researchers have proposed explanations ranging from irregular heart rhythm to genetic predisposition to accidental suffocation during sleep. Three studies to be presented at the American Epilepsy Society's (AES) 69th Annual Meeting parse the contributions of genetics to SUDEP in hopes of uncovering new strategies for prevention.
