FINDINGS
Calling an ambulance during an emergency, emailing a breaking news or journal article before a 5 p.m. deadline and maintaining conditions during the fifth week of a 6-week lab study, without altering the light or temperature, requires electricity and translates into time, money and lives. During critical moments, we appreciate the tiny particles and ions in electric currents that power our phones, computers or laboratory equipment. We seldom think about the speed of these connections or potential disruptors when conditions are stable.
Epileptic seizures happen in one of every 10 people who have experienced a traumatic brain injury (TBI). However, new research at The University of Texas at San Antonio (UTSA) has uncovered an innovative approach to possibly slow the progression of epilepsy. Researchers at UTSA have successfully removed new neurons that have developed after a brain injury to reduce seizures in mice. They believe that the technique could potentially reduce post-injury epilepsy.
Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and the NIST agency, have shown that quantum interference enables processing of large sets of data faster and more accurately than with standard methods. Their studies may boost applications of quantum technologies in e.g. artificial intelligence, robotics and medical diagnostics. The results of this work have been published in the Science Advances journal.
A team of researchers from Tokyo Institute of Technology has gained unprecedented insight into the inner workings of an atomic switch [1]. By investigating the composition of the tiny metal 'bridge' that forms inside the switch, their findings may spur the design of atomic switches with improved performance.
PHOENIX, Ariz., and BOSTON, Mass. -- July 19, 2019 -- A bone cancer known as osteosarcoma is genetically similar in dogs and human children, according to the results of a study published today by Tufts University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope. The findings could help break the logjam in the treatment of this deadly disease, which hasn't seen a significant medical breakthrough in nearly three decades.
NASA's Aqua satellite provided a visible image of Tropical Storm Danas moving through the East China Sea on July 19, 2019.
On July 19, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Danas that showed a large storm in the East China Sea. The storm is large and extends northeast into the Yellow Sea, east of the Korean Peninsula. The MODIS image also showed bands of strongest thunderstorms were east of the storm's center of circulation.
New research has discovered that cigarette butts - the most common form of litter on the planet - significantly reduce plant growth.
Led by academics from Anglia Ruskin University (ARU) and published in the journal Ecotoxicology and Environmental Safety, the study is the first to show the damage that cigarette butts can cause to plants.
Seeing was believing until technology reared its mighty head and gave us powerful and inexpensive photo-editing tools. Now, realistic videos that map the facial expressions of one person onto those of another, known as deepfakes, present a formidable political weapon.
But whether it's the benign smoothing of a wrinkle in a portrait, or a video manipulated to make it look like a politician saying something offensive, all photo editing leaves traces for the right tools to discover.
Operating rooms are a precious resource. They may account for 50 percent of a hospital's revenues and cost as much as $80 a minute. But figuring out how much time to allot for a surgery is a challenge every hospital faces.
Lithium metal anode is promising to upgrade the energy density of lithium ion batteries for its high specific capacity (3800 mAh g-1) and low voltage (-3.04 V vs. Li/Li+). But the safety issues caused by the dendrite growth and the instability in air caused by its high chemical activity limit its large-scale use as an electrode material. Lithium metal is highly sensitive to moisture and oxidative components in the air, leading to the generation of insulating products like lithium hydroxides on its surface and the resultant deterioration of the electrochemical performance.
More than half of our genome consists of transposons, DNA sequences that are reminiscent of ancient, extinct viruses. Transposons are normally silenced by a process known as DNA methylation, but their activation can lead to serious diseases. Very little is known about transposons but researchers in an international collaboration project have now succeeded for the first time in studying what happens when DNA methylation is lost in human cells. These findings provide new insight into how changes in DNA methylation contribute to diseases.
KAIST researchers have developed mobile software platform technology that allows a mobile application (app) to be executed simultaneously and more dynamically on multiple smart devices. Its high flexibility and broad applicability can help accelerate a shift from the current single-device paradigm to a multiple one, which enables users to utilize mobile apps in ways previously unthinkable.
Health systems in low- and middle-income countries (LMICs) are poorly prepared for the increasing number of people with high blood pressure, with more than two-thirds of people affected going without treatment, according to a new study led by researchers at Harvard T.H. Chan School of Public Health in collaboration with colleagues from more than 40 institutions around the world, including several ministries of health.
A special Lancet Series on Oral Health, published today in The Lancet, presents an "urgent need for radical reform" of oral healthcare to prioritize prevention and integrate dentistry into primary care. The series is comprised of two papers, both co-authored by Habib Benzian, DDS, MScDPH, PhD, the associate director of global health and policy for NYU College of Dentistry's World Health Organization (WHO) Collaborating Center for Quality-improvement, Evidence-based Dentistry--the only WHO Collaborating Center on oral health in the Americas.
