The thickness of the cortex in a region of the brain that specializes in facial recognition can predict an individual's ability to recognize faces and other objects.
In findings presented last week at the Meetings of the Society of Vertebrate Palaeontology in Texas, scientists identified the fossil remains of rats the size of small dogs found on the Indonesian island of Timor. According to archeological evidence from the area, humans (who were present in Timor starting at least 46,000 years ago) regularly hunted and butchered these megafauna.
The blood-brain barrier has been non-invasively opened in a patient for the first time. A team at Sunnybrook Health Sciences Centre in Toronto used focused ultrasound to enable temporary and targeted opening of the blood-brain barrier (BBB), allowing the more effective delivery of chemotherapy into a patient’s malignant brain tumor.
Diets high in meat may lead to an increased risk of developing renal cell carcinoma (RCC) through intake of carcinogenic compounds created by certain cooking techniques, such as barbecuing and pan-frying.
NASA's Swift spacecraft has detected its 1,000th gamma-ray burst (GRB). GRBs are the most powerful explosions in the universe, typically associated with the collapse of a massive star and the birth of a black hole.

A continuing look at a Maya village in El Salvador--frozen in time by a blanket of volcanic ash from 1,400 years ago--shows the farming families who lived there went about their daily lives with virtually no strong-arming by the elite royalty lording over the valley.
Using Hubble Space Telescope images, astronomers have conducted a "cosmic archeological dig" of our Milky Way's heart, uncovering the blueprints of our galaxy's early construction phase. The researchers uncovered for the first time a population of ancient white dwarfs -- smoldering remnants of once-vibrant stars that inhabited the Milky Way's core.
A group of scientists have developed a three-point plan to ensure the world’s protected areas meet new biodiversity targets set by the 193 signatory nations of the Convention on Biological Diversity's (CBD).
In the long term, cognitive behavior therapy is more effective at treating seasonal affective disorder that light therapy, considered the gold standard, a study to be published in the American Journal of Psychiatry found. Two winters after the initial treatment, 46 percent of research subjects given light therapy reported a recurrence of depression compared with 27 percent of those who were administered CBT. Depressive symptoms were also more severe for those who received light therapy.
When her dad was too sick to leave UAB Hospital, Sarah Williams brought her wedding to him with the help of the team providing his care.
Using computer models, researchers from the University of Bristol found that the feeding style and dietary preferences of dinosaurs was closely linked to how wide they could open their jaws. In the case of the meat-eating Tyrannosaurus rex, they could open their jaws wide, up to 90 degrees.
Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force between antiprotons is attractive and strong. The experiments were conducted at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory and will publish in Nature.
The evolution of male songbirds as the colorful consorts of drab female partners is more complicated than long thought, says a McMaster researcher on a team that looked at nearly 6,000 species for a massive study published in the journal Nature.

According to a surprising new study published in the Proceedings of the National Academy of Sciences on Monday, a decades-long decline in the death rate of middle-aged white Americans (age 45 to 54) has reversed in recent years. The causes are not the big killers such as heart disease and diabetes but an epidemic of suicides and substance abuse. The study was done by Nobel-winning researchers Angus Deaton and Anne Case of Princeton University.
New research shows that brain responses to written food words differ between lean individuals and those with obesity, and suggests that both stress and genetics could influence excess eating. The pair of studies led by Susan Carnell, PhD, member of The Obesity Society (TOS) and Assistant Professor of Psychiatry and Behavioral Sciences at Johns Hopkins University School of Medicine, reinforces the need to better understand how the external food environment interacts with our biology, and may aid the development of behavioral interventions to help individuals with obesity or those at high risk for the disease. The findings will be unveiled during an oral presentation on Tuesday, Nov. 3, and a poster presentation on Wednesday, Nov. 4, at The Obesity Society Annual Meeting at ObesityWeekSM 2015 in Los Angeles, CA.
Preschoolers who score lower on a working memory task are likely to score higher on a dropout risk scale at the age of 13, researchers at Université Sainte-Anne and the University of Montreal revealed today.
An archeological site in Jersey, UK has yielded a stash of artifacts from the end of the last Ice Age. The fragments include stone pieces engraved with criss-crossed lines, possibly made over 14,000 years ago. Initial reports determine that these were made by the Magdalenians, a hunter-gatherer culture which gradually re-colonised Europe at the end of the Ice Age, 16,000 to 13,000 years ago.
Possibly due to excessive wet weather, a fissure in Wyoming's Bighorn Mountains has grown to the size of nearly seven acres. Estimate to its size runs approximately 750 metres long and 50 metres wide.

The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
In a research lab in Germany, researchers are preparing to switch on a 52-foot wide fusion device called a stellarator, that could change the game in fusion energy.
A study in the Nov. 2 issue of Proceedings of the National Academy of Sciences is the first to fully document the demographic impacts of West Nile virus on North American bird populations. Data from bird-banding stations shows more species were hit than suspected, and half of those have yet to recover.
In their soon-to-be-published study, two Texas Tech University researchers said some of the venomous contents in the bats’ saliva likely evolved by recruiting ancestral genes to produce new transcript molecules rather than by creating completely new gene sequences.
A study led by Johns Hopkins Medicine researchers suggests that awakening several times throughout the night is more detrimental to people’s positive moods than getting the same shortened amount of sleep without interruption.
Diet diversity, as defined by less similarity among the foods people eat, may be linked to lower diet quality and worse metabolic health, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) and the Friedman School of Nutrition Science and Policy at Tufts University.
What people believe they want and what they prefer are not always the same thing. When outperformed as an element of romantic attraction, the difference between affinity and desirability becomes clearer as the distance between people gets smaller.
According to research led by University of Toronto and published in the The Astrophysical Journal, a close encounter with Jupiter approximately 4 billion years ago may have resulted in another giant planet’s ejection from the Solar System.
Seeking to improve the reliability of medical testing, an international team of experts has released new guidelines for doctors and scientists on how to best report their assessments of diagnostic tests.
Strong rain caused by El Nino in Chile's Atacama desert treated us to a beautiful flower show.
For centuries, cod were the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks are on the verge of collapse, hovering at 3-4% of sustainable levels. Even cuts to the fishery have failed to slow this rapid decline, surprising both fishermen and fisheries managers.
A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old, may be evidence for the presence of giant, unseen planets.
In the recent sci-fi hit, The Martian, the main character, astronaut Mark Watney (played by Matt Damon), manages to grow potatoes on the planet with a mix of ingenuity, science, and a bit of Hollywood make-believe. Could it work?
According to a study led by MIT, Volkswagen's emissions cheat on their diesel vehicles will cause 60 people in the U.S. To die 10 to 20 years prematurely.
Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. The simulation, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory, modeled the evolution of the universe from just 50 million years after the Big Bang to the present day—from its earliest infancy to its current adulthood. Over the course of 13.8 billion years, the matter in the universe clumped together to form galaxies, stars and planets; but we’re not sure precisely how.
If you don’t have health insurance, or your insurance coverage still leaves you with big bills, hospitals are supposed to let you know if you qualify for free or reduced-price care, and to charge you fairly even if you don’t. (That is, if they want to keep their tax-free nonprofit status.) But a new study finds many nonprofit hospitals have room to improve.
Much to their surprise, Scientists from the Rosetta mission say they have detected significant amounts of molecular oxygen coming out of a comet. This unexpected find may have implications for understanding how the solar system formed.
