WASHINGTON, January 17, 2020 -- Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing robots and robotic arms with grasping capabilities.
Traditional methods of vacuum suction and previous vacuum suction devices cannot maintain suction on rough surfaces due to vacuum leakage, which leads to suction failure.
Toward the end of 2017, a massive new region of magnetic field erupted on the Sun's surface next to an existing sunspot. The powerful collision of magnetic energy produced a series of potent solar flares, causing turbulent space weather conditions at Earth. These were the first flares to be captured, in their moment-by-moment progression, by NJIT's then recently opened Expanded Owens Valley Solar Array (EOVSA) radio telescope.
When NASA's Aqua satellite passed over the Southern Pacific Ocean it gathered water vapor data that provided information about the intensity of Tropical Cyclone Tino.
Tropical Cyclone Tino formed near Fiji in the Southern Pacific Ocean and NASA's Aqua satellite provided meteorologists with a look at the water vapor content of the storm showing potential for heavy rain.
Brain imaging may one day be used to help diagnose mental health disorders--including depression and anxiety--with greater accuracy, according to a new study conducted in a large sample of youth at the University of Pennsylvania and led by Antonia Kaczkurkin, PhD and Theodore Satterthwaite, MD.
And knowing more about the neurobiology behind psychiatric disorders could inform decisions about who might benefit from different therapies.
Simple LEGO bricks can be assembled to more complicated structures, which can be further associated into a wide variety of complex architectures, from automobiles, rockets, and ships to gigantic castles and amusement parks. Such an event of multi-step assembly, so-called 'hierarchical self-assembly', also happens in living organisms.
DURHAM, N.C. -- Engineers at Duke University have devised a model that can predict the early mechanical behaviors and origins of an earthquake in multiple types of rock. The model provides new insights into unobservable phenomena that take place miles beneath the Earth's surface under incredible pressures and temperatures, and could help researchers better predict earthquakes -- or even, at least theoretically, attempt to stop them.
The results appear online on January 17 in the journal Nature Communications.
Who wins in a competition is largely dependent on the opponent faced, yet the role of the environment in which the battle takes place should not be underestimated either. In sports, some skiers profit from icy over snowy grounds and some tennis players are weaker on sand than on grass. Similarly, within our bodies, the immune system sets the environment for the competition between multiple pathogens that infect us at the same time.

Hard plant foods may have made up a larger part of early human ancestors' diet than currently presumed, according to a new experimental study of modern tooth enamel from Washington University in St. Louis.
New UC Riverside research shows soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer's disease, anxiety, and depression.
Used for fast food frying, added to packaged foods, and fed to livestock, soybean oil is by far the most widely produced and consumed edible oil in the U.S., according to the U.S. Department of Agriculture. In all likelihood, it is not healthy for humans.
Assistant Professor Ohmura Shu and Professor Takahashi Akira of the Nagoya Institute of Technology and others have developed a charge model to describe photoexcited states of one-dimensional Mott insulators*1) under the JST Strategic Basic Research Programs. They have also succeeded in constructing a many-body Wannier function*2) as the localized basis state of the photoexcited states and calculating large-system, optical conductivity spectra that can be compared with experimental results.
Globally, arenas and stadiums that seat tens of thousands of people are filling up for whole weekends with crowds excited to their favourite sports stars sit on chairs and stare at screens. These fans are here to watch men and women play computer games, and researchers from Aalto and Tampere University are studying why.
An international team of Russian, Swedish and Ukrainian scientists has identified an effective strategy to improve the stability of two-dimensional black phosphorus, which is a promising material for use in optoelectronics.
The most effective mechanism of fluorination has been revealed. In addition to increased stability compared to previously proposed structures, the materials predicted by the researchers showed high antioxidative stability. The main results of the work have been presented in The Journal of Physical Chemistry Letters.
Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and transparent material that has different thermal conduction properties depending on the direction. While it can conduct heat extremely well in one direction, it shows good thermal insulation in the other direction.
Ever eaten something, gotten sick and then didn't want to eat that food again because of how it made you feel? That's because a signal from the gut to the brain produced that sickness, creating a taste aversion.
When it comes to playing a game of fetch, many dogs are naturals. But now, researchers report that the remarkable ability to interpret human social communicative cues that enables a dog to go for a ball and then bring it back also exists in wolves. The study appears January 16 in the journal iScience.
