New vaccine prevents herpes in mice, guinea pigs
Fri, 20 Sep 2019 14:53:50 EDT
A novel vaccine protected almost all mice and guinea pigs exposed to a new herpes virus. This may lead to the vaccine being tested in human studies.
Climate change study finds that maple syrup season may come earlier
Fri, 20 Sep 2019 14:53:48 EDT
Once winter nights dip below freezing and the days warm up above freezing sap begins to flow in sugar maples marking the start of the syrup season. With climate change, daily temperatures are on the rise, which affects sap flow and sugar content. By 2100, the maple syrup season in eastern North America may be one month earlier than it was during 1950 and 2017, according to a new study.
New method for the measurement of nano-structured light fields
Fri, 20 Sep 2019 12:46:54 EDT
Physicists and chemists have jointly succeeded in developing a so-called nano-tomographic technique which is able to detect the typically invisible properties of nano-structured fields in the focus of a lens. Such a method may help to establish nano-structured light landscapes as a tool for material machining, optical tweezers, or high-resolution imaging.
How to predict crucial plasma pressure in future fusion facilities
Fri, 20 Sep 2019 12:46:52 EDT
Feature describes improved model for forecasting the crucial balance of pressure at the edge of a fusion plasma.
Long-acting injectable multi-drug implant shows promise for HIV prevention and treatment
Fri, 20 Sep 2019 12:46:50 EDT
UNC researchers have created an injectable multi-drug delivery system that is removable, biodegradable and effective for up to a year in some cases. The author says the ability to administer multiple drugs with this implant is an important advancement in this research.
Anthropologist contributes to major study of large animal extinction
Fri, 20 Sep 2019 12:46:48 EDT
Anthropologist contributed a large, multi-institutional study explaining how the human-influenced mass extinction of giant carnivores and herbivores of North America fundamentally changed the biodiversity and landscape of the continent.
World's first gene therapy for glycogen storage disease produces remarkable results
Fri, 20 Sep 2019 12:46:45 EDT
The rare and deadly genetic liver disorder, GSD type Ia, affects children from infancy through adulthood, causing dangerously low blood sugar levels and constant dependence on glucose consumption in the form of cornstarch every few hours for survival. If a cornstarch dose is missed, the disease can lead to seizures and even death. A clinical trial originally set out to simply test the safety and dosage of the gene therapy for three patients with GSD Type Ia. The dramatic improvement in their lives was unexpected.
Water may be scarce for new power plants in Asia
Fri, 20 Sep 2019 12:46:43 EDT
Climate change and over-tapped waterways could leave developing parts of Asia without enough water to cool power plants in the near future, new research indicates. The study found that existing and planned power plants that burn coal for energy could be vulnerable.
Evolution of learning is key to better artificial intelligence
Fri, 20 Sep 2019 12:46:41 EDT
Since "2001: A Space Odyssey," people have wondered: could machines like HAL 9000 eventually exist that can process information with human-like intelligence? Researchers say that true, human-level intelligence remains a long way off, but a new article explores how computers could begin to evolve learning in the same way as natural organisms did -- with implications for many fields, including artificial intelligence.
Malawi study confirms lasting impact of life-saving technology
Fri, 20 Sep 2019 11:53:22 EDT
The Malawi Ministry of Health's national adoption of affordable, rugged, neonatal CPAP technology resulted in sustained improvements in the survival of babies with respiratory illness. The three-year study was conducted at 26 Malawi government hospitals that adopted Pumani CPAP devices as a part of routine hospital care between 2013 and 2016.
Surface melting causes Antarctic glaciers to slip faster towards the ocean
Fri, 20 Sep 2019 11:13:55 EDT
Study shows for the first time a direct link between surface melting and short bursts of glacier acceleration in Antarctica. During these events, Antarctic Peninsula glaciers move up to 100% faster than average. Scientists call for these findings to be accounted for in sea level rise predictions.
Untapped resource, or greenhouse gas threat, found below rifting axis off Okinawa coast
Fri, 20 Sep 2019 11:13:53 EDT
Using an automated method to create a high-resolution map of the seismic velocity below the seafloor, researchers found a large-scale gas reservoir in an area where the Earth's upper layers are being separated. This reservoir, the first of its kind, and the potential for others like it could have implications from natural resource or environmental standpoints depending on whether the trapped gas is methane or carbon dioxide and whether it remains trapped.
The best of two worlds: Magnetism and Weyl semimetals
Fri, 20 Sep 2019 11:13:51 EDT
Imagine a world in which electricity could flow through the grid without any losses or where all the data in the world could be stored in the cloud without the need for power stations. This seems unimaginable, but a path towards such a dream has opened with the discovery of a new family of materials with magical properties.
Why is the brain disturbed by harsh sounds?
Fri, 20 Sep 2019 11:13:49 EDT
Neuroscientists have analyzed how people react when they listen to a range of different sounds, the aim being to establish the extent to which repetitive sound frequencies are considered unpleasant. Their results showed that the conventional sound-processing circuit is activated but that the cortical and sub-cortical areas involved in the processing of salience and aversion are also solicited. This explains why the brain goes into a state of alert on hearing this type of sound.
Researchers find way to kill pathogen resistant to antibiotics
Fri, 20 Sep 2019 11:13:47 EDT
Researchers have demonstrated a new strategy in fighting antibiotics resistance: the use of artificial haem proteins as a Trojan horse to selectively deliver antimicrobials to target bacteria, enabling their specific and effective sterilization. The technique killed 99.9% of Pseudomonas aeruginosa, a potentially deadly, antibiotic-resistant bacterium present in hospitals. The strategy should also work for other dangerous bacteria.
Rethinking how cholesterol is integrated into cells
Fri, 20 Sep 2019 11:13:45 EDT
Cholesterol is best known in connection with cardiovascular disease, but cholesterol is also vital for many fundamental processes in the body. Researchers have now presented a completely new, ground-breaking model for the integration and incorporation of cholesterol into cells, with great impact on our understanding of this important process.
Super-resolution microscopy better than ever
Fri, 20 Sep 2019 11:13:43 EDT
They can make tiny cell structures visible: cutting-edge light microscopes offer resolutions of a few tenths of a nanometer -- in other words, a millionth of a millimeter. Until now, super-resolution microscopes were much slower than conventional methods, because more or finer image data had to be recorded.
Clarification of a new synthesis mechanism of semiconductor atomic sheet
Fri, 20 Sep 2019 10:28:48 EDT
Researchers have succeeded in clarifying a new synthesis mechanism regarding transition metal dichalcogenides (TMD), which are semiconductor atomic sheets having thickness in atomic order. Because it is difficult to directly observe the aspect of the growing process of TMD in a special environment, the initial growth process remained unclear, and it has been desirable to elucidate a detailed mechanism of synthesis to obtain high-quality TMD.
