If you've ever swatted a mosquito away from your face, only to have it return again (and again and again), you know that insects can be remarkably acrobatic and resilient in flight. Those traits help them navigate the aerial world, with all of its wind gusts, obstacles, and general uncertainty. Such traits are also hard to build into flying robots, but MIT Assistant Professor Kevin Yufeng Chen has built a system that approaches insects' agility.
Recently, research team led by academician GUO Guangcan from CAS Key Laboratory of Quantum Information of the University of Science and Technology of China (USTC) of CAS, has made an important progress in quantum information theory. Prof. LI Chuanfeng and Prof. XIANG Guoyong from the team, cooperated with Dr. Strelstov from University of Warsaw, investigated the imaginary part of quantum theory as a resource, and several important results have been obtained. Relevant results are now jointly published as Editors' Suggestion in Physical Review Letters and Physical Review A.
There's more to taste than flavor. Let ice cream melt, and the next time you take it out of the freezer you'll find its texture icy instead of the smooth, creamy confection you're used to. Though its flavor hasn't changed, most people would agree the dessert is less appetizing.
AMES, Iowa - Vaccines are an important tool in fighting porcine reproductive and respiratory syndrome (PRRS), but the fast-mutating virus that causes the disease sometimes requires the production of autogenous vaccines tailored to particular variants.
Volcanic basalt rocks in the Black Rock Desert, Utah.
If you drive south through central Utah on Interstate 15 and look west somewhere around Fillmore, you'll see smooth hills and fields of black rock. The area is, aptly, named the Black Rock Desert. It may not look like much, but you're looking at some of Utah's volcanoes.
Scientists regularly use remote sensing drones and satellites to record how climate change affects permafrost thaw rates -- methods that work well in barren tundra landscapes where there's nothing to obstruct the view.
But in boreal regions, which harbor a significant portion of the world's permafrost, obscuring vegetation can stymy even the most advanced remote sensing technology.
WASHINGTON, March 2, 2021 -- Tons of plastic debris get released into the ocean every day, and most of it accumulates within the middle of garbage patches, which tend to float on the oceans' surface in the center of each of their regions. The most infamous one, known as the Great Pacific Garbage Patch, is in the North Pacific Ocean.
The first UK COVID-19 lockdown saw a "rapid and sustained" fall in violence outside the home in the Welsh capital city, a new study led by Cardiff University has shown.
Researchers from Cardiff University's Crime and Security Research Institute (CSRI) and the US Centers for Disease Control and Prevention studied data from Cardiff's sole emergency department (ED) from March to June 2020 and compared it to weekly data from January 2019 onwards.
What The Study Did: Wearing surgical face masks for 30 minutes was not associated with changes in respiratory parameters or clinical signs of respiratory distress in this study of 47 infants and young children in Italy.
Authors: Silvia Bloise, M.D., of Sapienza University of Rome in Italy, is the corresponding author.

Washington, March 2, 2021--A first-of-its-kind analysis of parents' reviews of U.S. public K-12 schools, posted primarily from 2009 to 2019 on the popular school information site GreatSchools.org, found that most reviews were written by parents at schools in affluent neighborhoods and provided information that correlated strongly with test scores, a measure that closely tracks race and family income. Language associated with school effectiveness, which measures how much students improve in their test scores over time and is less correlated with demographics, was much less used.
WASHINGTON, March 2, 2021 -- Cardiovascular disease remains the number one cause of death globally. Unfortunately, the heart cannot regenerate new tissue, because the cardiomyocytes, or heart muscle cells, do not divide after birth.
In their paper, published in APL Bioengineering by AIP Publishing, Syracuse researchers developed a shape memory polymer to grow cardiomyocytes. Raising the material's temperature from 30 degrees Celsius to 37 degrees Celsius turned the polymer's flat surface into nanowrinkles, which promoted cardiomyocyte alignment.
New research suggests that the ability of green algae to eat bacteria is likely much more widespread than previously thought, a finding that could be crucial to environmental and climate science. The work, led by scientists at the American Museum of Natural History, Columbia University, and the University of Arizona, found that five strains of single-celled green algae consume bacteria when they are "hungry," and only when those bacteria are alive. The study is published today in The ISME Journal.
A 'Fish DJ' at The University of Queensland has used her knowledge of cool beats to understand brain networks and hearing in baby fish.
The DJ-turned-researcher used her acoustic experience to design a speaker system for zebrafish larvae and discovered that their hearing is considerably better than originally thought.
A Hong Kong Baptist University-led (HKBU) research team has developed a novel drug which has the potential to become a next-generation treatment for cancers associated with Epstein-Barr virus (EBV).
Modern electronics is approaching the limit of its capabilities, which are determined by the fundamental laws of physics. Therefore, the use of classical materials, for example, silicon, is no longer able to meet the requirements for energy efficiency of the devices. Currently, it is necessary to start searching for new materials, new principles of electronic devices' functioning.
