Combining experiment and theory, researchers from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) and the Max Planck Institute of Microstructure Physics have disentangled how laser pulses can manipulate magnetization via ultrafast transfer of electrons between different atoms.
SAN DIEGO--Rising sea surface temperatures and acidic waters could eliminate nearly all existing coral reef habitats by 2100, suggesting restoration projects in these areas will likely meet serious challenges, according to new research presented here today at the Ocean Sciences Meeting 2020.
BINGHAMTON, N.Y. - The combined effects of chemical contamination by road salt and invasive species can harm native amphibians, according to researchers at Binghamton University, State University of New York.
More portable, fully wireless smart home setups. Lower power wearables. Batteryless smart devices. These could all be made possible thanks to a new ultra-low power Wi-Fi radio developed by electrical engineers at the University of California San Diego.
For decades, researchers have considered the potential for cooling hot electronic devices by blowing on them with high-speed air jets. However, air jet cooling systems are not widely used today. Two of the biggest obstacles that prevent the use of these systems is their complexity and weight. Air jet systems must be made of metal to be able to handle the pressure associated with air jets whose speed can exceed 200 miles per hour.
A top ten of record-breaking US weather events of the last decade reveals Hurricane Harvey is the most extreme of the decade, and similar others were among the costliest and deadliest on record, according to magazine Weatherwise.
Hurricane Harvey, the 2017 storm that devastated Texas and Louisiana, is ranked first followed by the 2012 'Frankenstorm' Hurricane Sandy. In third place is deadly Hurricane Maria which ripped through Dominica, the US Virgin Islands, and Puerto Rico in the same year as Harvey.
Researchers at the University of California San Diego developed an ultrasound-emitting device that brings lithium metal batteries, or LMBs, one step closer to commercial viability. Although the research team focused on LMBs, the device can be used in any battery, regardless of chemistry.
Regular involvement of a GP in the care of children and young people with life-limiting conditions can reduce hospital admissions, a new study has found.
The research - led by the Martin House Research Centre team at the University of York - discovered that children who had less regular contact with a GP had 15% more emergency admissions and 5% more A&E visits than those with more regular consultations.
As power plants and energy stores, mitochondria are essential components of almost all cells in plants, fungi and animals. Until now, it has been assumed that these functions underlie a static structure of mitochondrial membranes. Researchers at the Heinrich Heine University Düsseldorf (HHU) and the University of California Los Angeles (UCLA), supported also by the Center for Advanced Imaging (CAi) of HHU, and have now discovered that the inner membranes of mitochondria are by no means static, but rather constantly change their structure every few seconds in living cells.
Traditional cardiovascular risk factors often assessed in an annual physical, such as blood pressure, cholesterol levels, diabetes, and smoking status, are at least as valuable in predicting who will develop coronary heart disease (CHD) as a sophisticated genetic test that surveys millions of different points in DNA, a study led by a UT Southwestern Medical Center researcher suggests. The findings, published Feb. 18, 2020, in JAMA, support the utility of these tried-and-true methods.
Because pulse trains achieve excellent performance with a simple laser setup, passively mode-locked fiber lasers (MLFLs) based on nonlinear polarization evolution (NPE) have numerous applications. However, NPE-based MLFLs are difficult to operate in the desired pulsation regime via manual polarization tuning and are prone to detaching from the desired regime due to polarization drift from environmental disturbances.
Enzymes with flavin cofactor play an important part in plants, fungi, bacteria and animals: as oxygenases they incorporate oxygen into organic compounds. For instance this allows people to excrete foreign substances more effectively. Until now scientists were agreed that such flavin-dependent oxygenases use flavin C4a-peroxide as oxidizing agent. This is formed by the C4a-atom of the flavin cofactor reacting with atmospheric oxygen (O2), before one of the two oxygen atoms are transferred to the compound. A team headed by Dr.
Malaria parasites can sense a molecule produced by approaching immune cells and then use it to protect themselves from destruction, according to new findings published today in eLife.
The study, led by scientists from the Agency for Science, Technology and Research's (A*STAR) Singapore Immunology Network (SIgN), reveals a previously unknown reversible mechanism that malaria uses to evade the immune system, paving the way towards new antimalarial drugs.
An analysis of 149 scientific studies has identified 24 genetic variants which predispose women to endometrial cancer.
The systematic review, led by Professor Emma Crosbie from The University of Manchester, could help scientists develop targeted screening and prevention strategies for women at greatest risk of the disease.
Eating a Mediterranean diet for a year boosts the types of gut bacteria linked to 'healthy' ageing, while reducing those associated with harmful inflammation in older people, indicates a five-country study, published online in the journal Gut.
As ageing is associated with deteriorating bodily functions and increasing inflammation, both of which herald the onset of frailty, this diet might act on gut bacteria in such a way as to help curb the advance of physical frailty and cognitive decline in older age, suggest the researchers.
