Adrenaline is considered crucial in triggering a “fight or flight” response, but new research shows the response can’t get started without a hormone made in bone.
Producers already use the software for many purposes. For example, many citrus growers want to take inventory of their trees, including the size of each tree. Gathering this data normally requires farmers to manually count trees and measure them. The software streamlines that process. They can also use the software to see which parts of their fields – or which fruit varieties -- perform better.
A team of scientists including Will Farr, PhD, an astrophysicist at Stony Brook University, has found a way for the first time to detect multiple tones of a black hole ringing like a bell -- something that most astrophysicists thought would not be possible for a decade or more.
Science Snapshots: messenger proteins, new TB drug, artificial photosynthesis
Papillomavirus has traditionally been considered strictly a sexually transmitted disease, but a recent study found that rabbit and mouse papillomaviruses could be transferred by blood to their respective hosts.
With the 2020 U.S. presidential election fast approaching, should the youngest members of society be engaged in the political discussion? Findings of a new collaborative study — conducted by researchers at the University of Kentucky, University of Kansas, University of Texas at Austin, Whitman College and University of Texas at Tyler — aim to answer that question by providing insight into children's reactions to the 2016 presidential election.
Sixteen years ago, a research group at Mayo Medical School published results showing that a protein called TRAIL can kill cells that cause liver fibrosis but no one seemed to follow up on these findings. Now, researchers at Johns Hopkins Medicine have improved on this protein and shown that it selectively kills cells that cause the hardening of skin associated with scleroderma, effectively reversing the condition in mice genetically engineered to mimic the disease. A report on these results was published earlier this year in Nature Communications.
The First-year Research Immersion (FRI) program at Binghamton University, State University of New York has proven that young college students are capable of leading real research. And according to a new study, students in FRI do better when the instructors who oversee their projects are provided extra training.
Patients with acute myeloid leukemia (AML), a leukemia which arises from bone marrow tissue, often see remission following their initial treatment, but for patients whose cancer returns, there are few options. One such option is guadecitabine, a novel DNA hypomethylating drug which slows problematic changes to a person’s epigenetic profile, but the drug is ineffective in a select number of relapsed or refractory AML patients and there has not been a way to determine who stands to benefit and who does not. However, researchers from the Coriell Institute for Medical Research have found certain biomarkers which can indicate a patient’s likelihood for success. Their findings were published in Clinical Epigenetics in July.
Contrary to misleading reports in the media and online, the disciplinary strategy of "time-out" is not associated with increased behavior problems or other long-term negative effects in children, reports a study in the Journal of Developmental & Behavioral Pediatrics

Scientists at the Lowy Medical Research Institute (LMRI) have discovered one cause of a progressive, debilitating eye disease called macular telangiectasia type 2 (MacTel). The work, using genetic, clinical and biochemical studies has implications for other retinal eye diseases, as well as peripheral neuropathies.
Restricting the sale of menthol cigarettes to tobacco specialty shops may reduce the number of retailers and increase the cost of smoking, according to new research from the Brown School at Washington University in St. Louis.“Targeting the tobacco retail environment is rapidly emerging as the next frontier in tobacco control,” said Todd Combs, research assistant professor at the Brown School and lead author of the study “Modelling the Impact of Menthol Sales Restrictions and Retailer Density Reduction Policies: Insights From Tobacco Town Minnesota,” published Aug.

Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a Rutgers-led study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.

St. Jude Children’s Research Hospital scientists have identified a molecule that plays a pivotal role in determining the fate of cells under stress, much like a Roman emperor deciding the fate of gladiators in the coliseum.
An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way – a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy. This hourglass-like feature, which dwarfs all other radio structures in the galactic center, is likely the result of a phenomenally energetic burst that erupted near the Milky Way’s supermassive black hole a few million years ago.
A new Penn Medicine study, published in Nature, revealed, in mice, that CART T-cell therapy may now be harnessed to treat heart disease. Researchers used genetically modified T cells to target and remove activated fibroblasts that contribute to the development of cardiac fibrosis.
