Immune cells usually ignored by neuroscientists appear to play an important role in determining whether an animal’s sexual behavior will be more typical of a male or female, according to research.
An aquarium fish that senses the Earth’s magnetic field as it swims could help unlock how diseases such as Parkinson’s and other neurological disorders function. Michigan State University scientists are the first to discover a navigational gene in glass catfish called the electromagnetic-perceptive gene, or EPG, that responds to certain magnetic waves. They’ve already developed a way to use it to control movement in mice.
Scientists at The University of Texas Health Science Center at Houston (UTHealth) have identified the brain networks that allow you to think of an object name and then verbalize that thought. The study appeared in the July issue of BRAIN. It represents a significant advance in the understanding of how the brain connects meaning to words and will help the planning of brain surgeries.
Collaboration powers machine learning software that performs data analytics on petabyte-sized data sets in series of successful test runs.
Research on how adults deal with adversity has been dominated by studies claiming the most common response is uninterrupted and stable psychological functioning. In other words, this research suggests that most adults are essentially unfazed by major life events such as spousal loss or divorce. These provocative findings have also received widespread attention in the popular press and media.
Scientists at the University of California, Los Angeles present research on a curious cosmic phenomenon known as “whistlers” -- very low frequency packets of radio waves that race along magnetic field lines. Appearing in the Physics of Plasmas, the study provides new insights into the nature of whistlers and space plasmas and could one day aid in the development of practical plasma technologies with magnetic fields, including spacecraft thrusters that use charged particles as fuel.
Researchers comparing several clonal strains of isoniazid-sensitive and resistant tuberculosis bacteria found shared changes to mycobacterial metabolism that bolster the evidence for a new proposed drug target.
In the first comprehensive study of the forefoot joints of ancient hominins, to be published online in PNAS, an international team of researchers conclude that adaptations for bipedal walking in primates occurred as early as 4.4 million years ago
A new study led by the University of Washington uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.
Scientists at Memorial Sloan Kettering Cancer Center (MSK) announced that they have built a new model of genetically engineered immune cells in mice that may allow them to fight solid tumors.
The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer and cause global warming, but many HVAC systems still use synthetic refrigerants that violate those international agreements and inflict environmental damage. Recently, Iranian researchers investigated how natural refrigerants could be used in geothermal heat pumps to reduce energy consumption and operating costs. They report their findings in the Journal of Renewable and Sustainable Energy.
Researchers from the University of Florida and the Federal University of Mato Grosso do Sul in Brazil have used state of the art simulations to assess the effect of both pH and redox potential, or rate of electron transfer, on a biomolecule.
Experts in fluid dynamics and kids jumping into a pool both know that an object falling into a liquid makes a splash. A new study finds that a single layer of a penetrable fabric – in this case, toilet paper – causes a wettable ball to make an especially tall splash, but additional layers can stop the splash entirely.
For the first time, Mount Sinai researchers have identified a way to make large numbers of immune cells that can help prevent cancer reoccurrence, according to a study published in August in Cell Reports.

Study from the American Cancer Society, published in JNCCN--Journal of the National Comprehensive Cancer Network, found cancer patients who were more satisfied with the communication they received, had better health results at lower costs
A Johns Hopkins expert panel of health care providers and patients have announced what is, to their knowledge, the nation’s first set of operation-specific opioid prescribing guidelines. The guidelines are based on the premise that opioid prescribing limits should be based on the operation performed rather than a blanket approach. The ranges offered for each of 20 common operations generally call for reductions from the current rates of opioid prescription, and the researchers say that patients themselves favor using less of the drugs than physicians often prescribe.
Amid the chaos of getting kids out the door in the morning and taming the hangry monsters that get off the bus in the afternoon, parents may be overlooking a critical part of setting their kids up for success during the school year: a nutrient-rich diet. One out of two kids ages 9 and up are not getting enough calcium, vitamin D and potassium – nutrients they need to grow, learn and play. And, most kids younger than nine are falling short on vitamin D and potassium.
A valuable cache of brain cancer biomedical data, one of only two such large collections in the country, has been made freely available worldwide by researchers at Georgetown Lombardi Comprehensive Cancer Center.
Cows with shorter hair are cooler, and thus, more productive, said Raluca Mateescu, an associate professor of animal sciences at the UF Institute of Food and Agricultural Sciences. A calm cow is also more productive than an agitated one, Mateescu said.
The diabetes epidemic in Guatemala is worse than previously thought: more than 25 percent of its indigenous people, who make up 60 percent of the population, suffer from type 2 diabetes or pre-diabetes, suggests a new study published in PLOS One from researchers at the Penn Center for Global Health.
Hundreds of polymers - which could kill drug-resistant superbugs in novel ways - can be produced and tested using light, using a method developed at the University of Warwick.

Switching anti-psychotic medications does not improve clinical outcomes in patients with first-episode schizophrenia who haven’t responded to treatment, Mount Sinai researchers have shown for the first time.
Treatment guidelines say patients who undergo minimally invasive aortic heart valve replacements should receive two antiplatelet drugs to reduce the risk of dangerous blood clots. A Loyola Medicine study has found that a single antiplatelet drug may work just as well, with lower risks of life-threatening bleeding and other complications.
It’s a longstanding mystery why salamanders can perfectly regenerate their tails whereas lizard tails grow back all wrong. By transplanting neural stem cells between species, Pitt researchers have discovered that the lizard’s native stem cells are the primary factor hampering tail regeneration.
Medicare patients nationwide have low rates of preventive care visits – with the lowest rates found in older adults of minority race/ethnicity, reports a study in the September issue of Medical Care. The journal is published in the Lippincott portfolio by Wolters Kluwer.
In 1993, neurologist Camilo Gomez, MD, coined a phrase that became a fundamental rule of stroke care: "Time is brain!" The longer therapy is delayed, the less chance it will succeed. But the "time is brain" rule is not as simple as it once seemed, Dr. Gomez now reports in the Journal of Stroke & Cerebrovascular Diseases.

A new study carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility has confirmed that increasing the number of neutrons as compared to protons in the atom’s nucleus also increases the average momentum of its protons. The nuclear physics result, which has implications for the dynamics of neutron stars, has been published in the journal Nature.
Although national guidelines advise doctors to discuss the benefits and harms of lung cancer screening with high-risk patients because of a high rate of false positives and other factors, those conversations aren’t happening the way they should be, according to a study by researchers from the University of North Carolina Lineberger Comprehensive Cancer Center.
The study’s findings lay the framework for applying deep learning and computer vision techniques to radiological imaging.
Adopting an Islamic concept of coping with spiritual struggles, known as “spiritual jihad,” is associated with post-traumatic growth and virtuous behaviors—and related to reductions in anxiety and depression, according to a new Case Western Reserve University study published in the journal Religions.
Fruit flies don’t appear to use their tiny, translucent wings for optimal flight, as one might expect. The speedy appendages seem to be doing double duty, helping the insect sniff out food, mates and other important scents, according to new research from The Ohio State University.
Researchers at Duke Cancer Institute have tracked the missing T-cells in glioblastoma patients. They found them in abundance in the bone marrow, locked away and unable to function because of a process the brain stimulates in response to glioblastoma, to other tumors that metastasize in the brain and even to injury.
A new approach to find unmarked gravesites could help narrow the scope and potentially speed up the search for clues during crime scene investigations. Geospatial researchers with the Department of Energy’s Oak Ridge National Laboratory and forensic scientists at University of Tennessee used LIDAR to detect telltale signs of recently buried human remains.
Pedestrian injuries and fatalities in the U.S. have steadily increased during recent years. In 2015, 5,376 pedestrians were killed and 70,000 injured. Prior research showed an association between the number of neighborhood alcohol stores and risk of pedestrian injury. However, it is unclear whether this was because alcohol stores were located in dense retail areas with already-heavy pedestrian traffic, or whether alcohol stores pose a unique neighborhood risk. This study compared the number of pedestrian injuries that occur near alcohol stores to those that occur near similar retail stores that do not sell alcohol.
Johns Hopkins Medicine researchers say a study designed to see if reducing the amount of anesthesia reduces the risk of postoperative delirium in older patients surprisingly found that lighter sedation failed to do so in severely ill people undergoing hip fracture repair.
Adolescents with a strong hand grip — an indicator of overall muscle strength — have better odds of being healthy over time, according to a two-year study of 368 elementary school children. A simple, non-invasive measure of grip strength can help identity risks of pre-diabetes and cardiovascular disease, issues of increasing concern as obesity in youths rises.
