LAWRENCE -- Researchers from the University of Kansas have described three genera and 17 new species of water scavenger beetles from the Guiana and Brazilian Shield regions of South America, areas seen as treasure houses of biodiversity. The beetles from the countries of French Guiana, Suriname, Brazil, Guyana and Venezuela were discovered through fieldwork and by combing through entomological collections at the Smithsonian Institution and KU.

Researchers studied users of an online anime platform that provided individual-level data on users' friendship networks, anime watching behaviors, forum posts, and ratings.
Both word-of-mouth and the example of others, (i.e., others' decisions of what to watch or following someone else's lead), are two of the most powerful sources in social learning.
Infrared imagery from NASA's Terra satellite found just a few scattered areas of cold clouds in the Eastern Pacific Ocean's Tropical Depression Henriette on August 13.
NASA's Terra satellite uses infrared light to analyze the strength of storms by providing temperature information about the system's clouds. The strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
Scientists at the National University of Science and Technology "MISIS" (NUST MISIS) have identified a new mechanism for removing magnetic nanoparticles through the kidneys, which will help to create more effective and safe drugs. The results of the study are published in the Journal of Controlled Release.
In 1935, the physicist Erwin Schrödinger put forward the thought experiment with the quantum cat, in which the cat is enclosed in a box together with a radioactive sample, a detector and a lethal amount of poison. If the radioactive material decays, the detector triggers an alarm and the poison is released. The special feature is that according to the rules of quantum mechanics, unlike everyday experience, it is not clear whether the cat is dead or alive. It would be both at the same time until an experimenter takes a look.
Scientists have developed an automated tool for mapping the movement of particles inside cells that may accelerate research in many fields, a new study in eLife reports.
The movements of tiny molecules, proteins and cellular components throughout the body play an important role in health and disease. For example, they contribute to brain development and the progression of some diseases. The new tool, built with cutting-edge machine learning technology, will make tracking these movements faster, easier and less prone to bias.
The summer heatwave of 2003 triggered a rockfall that shocked both researchers and the general public: 1,500 cubic metres of rock broke away from the Hoernli ridge - a volume roughly equivalent to two houses. The fracture event exposed bare ice on the surface of the steep scarp. Experts soon realised that the record temperatures had warmed the rock down to such a depth that the ice contained in its pores and fissures had melted. This effectively caused a sudden reduction of the bonding holding the rock mass together.
An international team of subsurface explorers from the University of Adelaide in Australia and the University of Aberdeen in Scotland have uncovered a previously undescribed 'Jurassic World' of around 100 ancient volcanoes buried deep within the Cooper-Eromanga Basins of central Australia.
BELLINGHAM, Washington, USA and CARDIFF, UK - A new paper in Advanced Photonics, an open-access journal co-published by SPIE, the international society for optics and photonics, and Chinese Laser Press (CLP), demonstrates distinct improvements to the inference and generalization performance of diffractive optical neural networks.
Over the recent decade, total human impacts to the world's oceans have, on average, nearly doubled and could double again in the next decade without adequate action. That's according to a new study by researchers from the National Center for Ecological Analysis and Synthesis (NCEAS) at UC Santa Barbara.
Under the leadership of the head of the laboratory for the synthesis of new crystalline materials of the Samara Center for Theoretical Materials Science (SCTMS) of the Samara Polytech candidate of chemical sciences Eugeny Alexandrov and the head of the department "Chemistry and Technology of Chemical Compounds of Nitrogen", doctor of technical sciences Andrei Pimenov, the synthesis of the first metal-organic polymeric materials, or metal-organic frameworks (MOFs).
A new spectroscopic method now makes it possible to measure and visualise the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr Yana Vaynzof, a physicist at Heidelberg University. This novel visualisation technique enables scientists to study the physical principles of organic photovoltaics with extreme precision and to better understand processes such as energetic losses.
COLUMBUS, Ohio - Racial and ethnic gaps in criminal sentences have declined, in some cases significantly, since the mid-1990s, a new analysis of state, county and federal data suggests.
For example, the overall sentence length gap between whites and blacks in federal courts decreased by more than 80 percent between 1996 and 2016.
The analysis also found declines in the disparity between how often blacks are sentenced to prison compared to whites.
The greater frequency of droughts, combined with underlying economic, social, and environmental risks means that dry spells have an increasingly destructive impact on vulnerable populations, and particularly on children in the developing world. In a new study by researchers from IIASA and the USA, the team set out to map at-risk populations at the global scale.
New York, NY--August 12, 2019--A novel neck brace, which supports the neck during its natural motion, was designed by Columbia engineers. This is the first device shown to dramatically assist patients suffering from Amyotrophic Lateral Sclerosis (ALS) in holding their heads and actively supporting them during range of motion. This advance would result in improved quality of life for patients, not only in improving eye contact during conversation, but also in facilitating the use of eyes as a joystick to control movements on a computer, much as scientist Stephen Hawkins famously did.
