Chestnut Hill, Mass. (5/30/2019) - Researchers have paired a specialized diet and a tumor-fighting drug and found the non-toxic combination helps to destroy the two major cells found in an aggressive form of brain cancer, the team reports in the online edition of the Nature group journal Communications Biology.
WEST LAFAYETTE, Ind. -- In 2004, researchers discovered a super thin material that is at least a 100 times stronger than steel and the best known conductor of heat and electricity.
This means that the material, graphene, could bring faster electronics than is possible today with silicon.
But to truly be useful, graphene would need to carry an electric current that switches on and off, like what silicon does in the form of billions of transistors on a computer chip. This switching creates strings of 0s and 1s that a computer uses for processing information.
Work opens a path to precise calculations of the structure of other nuclei.
In a study that combines experimental work and theoretical calculations made possible by supercomputers, scientists have determined the nuclear geometry of two isotopes of boron. The result could help open a path to precise calculations of the structure of other nuclei that scientists could experimentally validate.
Do we see a pear or an apple? The occipital cortex in our brain will activate itself to recognise it. A piece of bread or a nice plate of pasta with sauce? Another region will come into play, called middle temporal gyrus. Different regions are implicated in recognition of different foods, raw in one case and processed in the other, because two components of the so-called "semantic memory", the one that we always use to recognise the world around us, are involved.
WASHINGTON -- Many people, including educators, believe learning styles are set at birth and predict both academic and career success even though there is no scientific evidence to support this common myth, according to new research published by the American Psychological Association.
Even a short stay for travelers in cities with high levels of air pollution leads to breathing problems that can take at least a week from which to recover, a new study shows.
Led by researchers at NYU School of Medicine, the study is the first of its kind, say the authors, to analyze pollution-related coughing and breathing difficulties, and recovery times upon returning home, in healthy, young adults traveling internationally.
A new study led by Boston Medical Center's Grayken Center for Addiction shows that opioid-related overdose deaths involving another substance is now the norm, not the exception, in Massachusetts. The researchers analyzed opioid overdose death data from the Massachusetts Department of Public Health, which showed that 82 percent of those deaths involved an opioid and another substance, including stimulants. Of importance, the researchers also identified specific sociodemographic factors and social determinants of health associated more with polysubstance opioid-related overdose deaths.
Combining big data with artificial intelligence has allowed University of Copenhagen researchers to determine whether you wrote your assignment or whether a ghostwriter penned it for you - with nearly 90 percent accuracy.
WASHINGTON - Fewer than 60% of young women diagnosed with sexually transmitted infections (STIs) in the emergency department fill prescriptions for antimicrobial therapy to treat these conditions, according to a research letter published online May 28, 2019, by JAMA Pediatrics.
A global study shows people born very preterm or with very low birthweight have a high risk of lung disease and are not reaching their full airway capacity by early adulthood.
The research found those born before 32 weeks of pregnancy or with a birthweight of less than 1501g are four times more likely to have airflow in worrying clinical ranges in early adulthood than those born on time.
Practice results in better learning. Consider learning a musical instrument, for example: the more one practices, the better one will be able to learn to play. The same holds true for cognition and visual perception: with practice, a person can learn to see better--and this is the case for both healthy adults and patients who experience vision loss because of a traumatic brain injury or stroke.

The number of asylum seekers on wait lists in Mexican border cities or those waiting to get on these lists has grown to 18,700, according to a new report.
'Statistical significance' is one of the most widely misunderstood phrases in science, according to a 2013 Scientific American article.
It's a controversial topic. Probability values (p-values) have been used as a way to measure the significance of research studies since the 1920s, with thousands of researchers relying on them since. With this reliance, though, comes misunderstanding and, therefore, misuse.
This misunderstanding is what the latest episode of the How Researchers Changed the World podcast explores, in conversation with statistician Ron Wasserstein.
Immune cells prioritise the clearance of dead cells overriding their normal migration to sites of injury
University of Sheffield research paves the way for new therapies to manipulate how white blood cells get to and are kept at sites of injuries during healing
Dead cells disrupt immune responses and undermine defence against infection, new research has found.
