New data from the NASA/ESA Hubble Space Telescope have provided the strongest evidence yet for mid-sized black holes in the Universe. Hubble confirms that this "intermediate-mass" black hole dwells inside a dense star cluster.
Severe flooding throughout the Midwest--which triggered a delayed growing season for crops in the region--led to a reduction of 100 million metric tons of net carbon uptake during June and July of 2019, according to a new study.
If you see people walking down a street and coming to a junction, it's difficult to predict which direction they might take. But, if you see people sitting in separate boats, floating down a stream, and the stream splits into two channels, it's likely that most, if not all, of them will be carried down one channel, the channel that has the stronger flow.
LOS ALAMOS, N.M., March 30, 2020 -- New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're moving. Observations of record-breaking gamma rays prove the robustness of Lorentz Invariance - a piece of Einstein's theory of relativity that predicts the speed of light is constant everywhere in the universe. The High Altitude Water Cherenkov observatory in Puebla, Mexico detected the gamma rays coming from distant galactic sources.
WASHINGTON--A chemical used in hydraulic fracturing, commonly called fracking, has the potential to interfere with reproductive hormones in men, according to research accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
The study found the chemical can block the effects of testosterone and other male sex hormones known as androgens.
WASHINGTON--Most resident physicians training in internal medicine do not feel adequately prepared to manage obesity in their patients, a new survey from a California residency program finds. The results were accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and will be published in a special supplemental section of the Journal of the Endocrine Society.
WASHINGTON--A type of artificial intelligence called machine learning can help predict which patients will develop diabetes, according to an ENDO 2020 abstract that will be published in a special supplemental section of the Journal of the Endocrine Society.
Researchers at the University of California San Diego discovered that high blood levels of RNA produced by the PHGDH gene could serve as a biomarker for early detection of Alzheimer's disease. The work could lead to the development of a blood test to identify individuals who will develop the disease years before they show symptoms.
The team published their findings in Current Biology.
The agave plant used to make tequila could be established in semi-arid Australia as an environmentally friendly solution to Australia's transport fuel shortage, a team of researchers at the University of Sydney, University of Exeter and University of Adelaide has found.
The efficient, low-water process could also help produce ethanol for hand sanitiser, which is in high demand during the COVID-19 pandemic.
WASHINGTON, March 23, 2020 -- Refreshable braille displays translate information from computer screens into raised characters, often along the bottom of a keyboard. But this technology can cost thousands of dollars and is limited, typically displaying a string of characters much shorter than most sentences. Researchers now report an improved material that could take these displays to the next level, allowing those who are blind or who have low vision to more easily understand text and images, while lowering cost.
Dr. Soon Moon Jeong's research team in the Division of Energy Technology at DGIST has developed a new structure of luminescence technology. This will enable the production of light-emitting elements that overcome the limitations of existing methods, expecting to greatly help improve the efficiency of light-emitting elements used in various ways such as billboards and banners.
Research shows that physical and sexual abuse are risk factors for depression in adolescents. However, we know less about the differences between emotional abuse and neglect as critical risk factors in teenage depression. A new longitudinal study examined the depressive effects of these different types of maltreatment among a group of youth at risk of being maltreated. The study found that emotional abuse and neglect affect adolescent depression differently depending on gender and ethnicity.
Warning labels should be displayed on petrol pumps, energy bills, and airline tickets to encourage consumers to question their own use of fossil fuels, say health experts in The BMJ today.
Like health warnings on cigarette packets, the labels should state clearly that continuing to burn fossil fuels worsens the climate emergency, with major projected health impacts increasing over time.
In a study with the longest follow-up to date of patients with a high-risk form of heart disease known as left main coronary artery disease (LMCAD), researchers found no significant differences in rates of death, heart attack or stroke between patients who were treated with a stent and those who underwent heart bypass surgery. The research, presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology (ACC.20/WCC), also showed that more patients receiving a stent had to have the procedure repeated during the study period.
AMHERST, Mass. - In a new paper, Thomas Russell and postdoctoral fellow Ganhua Xie, at the University of Massachusetts Amherst and Lawrence Berkeley National Laboratory, report that they have used capillary forces to develop a simple method for producing self-assembling hanging droplets of an aqueous polymer solution from the surface of a second aqueous polymer solution in well-ordered arrays.
