WEST LAFAYETTE, Ind. - Finding inexpensive solutions for propelling CubeSats is one of the most critical components of the rapidly growing industry of commercial launches of satellites the size of a loaf of bread. The small size and relatively low cost have made CubeSats popular choices for commercial launches in recent years.
They outlived mammoths and saber-toothed tigers. But without dramatic action to reduce climate change, new research shows Joshua trees won't survive much past this century.
UC Riverside scientists wanted to verify earlier studies predicting global warming's deadly effect on the namesake trees that millions flock to see every year in Joshua Tree National Park. They also wanted to learn whether the trees are already in trouble.
Over the past decade, a major trend in electronics has been the development of sensors, displays and smart devices which are seamlessly integrated onto the human body. Most of these wearable devices are singularly connected to a user's smart phone and transmit all data via Bluetooth or Wi-Fi signals. But as consumers wear increasing numbers of wearable devices, and as the data they transmit increases in sophistication, more innovative connection methods are being sought after.

Industrial robots are now widely used and are indispensable in car manufacturing and in other fields. Conventional robot hands are suitable for grasping hard objects of fixed form, whereas it is not easy to grasp complicated objects or to gently grasp soft objects. It is also necessary, under various conditions, to respond to physical characteristics of objects such as surface characteristics: dry, wet, etc.
Removing new neurons born after a brain injury reduces seizures in mice, according to new research in JNeurosci. This approach could potentially help prevent post-injury epilepsy.
New neurons generated following a brain injury often do not develop normally. Left untreated, these cells may contribute to the development of epilepsy.
A five-year collaborative study by Chinese and Canadian scientists has produced a theoretical model via computer simulation to predict properties of hydrogen nanobubbles in metal.
The international team was composed of Chinese scientists from the Institute of Solid State Physics of the Hefei Institute of Physical Science along with their Canadian partners from McGill University. The results will be published in Nature Materials on July 15.
A global study, led by researchers at King's College London and University of North Carolina at Chapel Hill, suggests that anorexia nervosa is at least partly a metabolic disorder, and not purely psychiatric as previously thought. The research was published in Nature Genetics today.
The large-scale genome-wide association study, undertaken by over 100 academics worldwide, identified eight genetic variants linked to anorexia nervosa. The results suggest that the genetic origins of the disorder are both metabolic and psychiatric.
CAMBRIDGE, MA -- For decades, research has shown that our perception of the world is influenced by our expectations. These expectations, also called "prior beliefs," help us make sense of what we are perceiving in the present, based on similar past experiences. Consider, for instance, how a shadow on a patient's X-ray image, easily missed by a less experienced intern, jumps out at a seasoned physician. The physician's prior experience helps her arrive at the most probable interpretation of a weak signal.
A new large-scale genome-wide association study published in Nature Genetics, has identified eight genetic variants significantly associated with anorexia nervosa; and the research shows that the origins of this serious disorder appear to be both metabolic and psychiatric.
CRISPR is often thought of as "molecular scissors" used for precision breeding to cut DNA so that a certain trait can be removed, replaced, or edited, but Yiping Qi, assistant professor in Plant Science & Landscape Architecture at the University of Maryland, is looking far beyond these traditional applications in his latest publication in Nature Plants.
Numerical models are a key tool for climate scientists in understanding the past, present and future climate change arising from natural, unforced variability or in response to changes, according to Dr Qing Bao, Research Fellow at the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences (CAS), and the corresponding author of a recently published study.
A new paper details how small samples of ubiquitous building materials, such as tile or brick, can be used to test whether a facility has ever stored high enriched uranium (HEU), which can be used to create nuclear weapons. The technique could serve as a valuable forensic tool for national or international efforts related to nuclear nonproliferation and security.
Tropical Storm Barry continued to linger in the Gulf of Mexico, generating a lot of heavy rainfall on Saturday, July 13, 2019. Barry was just under the threshold of being classified a Category 1 hurricane and is expected to become one before landfall. NASA's Aqua satellite analyzed cloud top temperatures in the storm which gave an indication of the storm's strength.
Researchers presented a new strategy for extending sodium ion batteries' cyclability using copper sulfide as the electrode material. This strategy has led to high-performance conversion reactions and is expected to advance the commercialization of sodium ion batteries as they emerge as an alternative to lithium ion batteries.
Back in 2004, the physics community was just beginning to recognize the existence of truly two-dimensional (2D) material, graphene. Fast forward to 2019, scientists explore a breadth of different 2D materials, expecting to uncover more of their fundamental properties. The frenzy behind these new 2D materials lies in their fascinating properties: materials thinned down to only a few atoms work very differently from their 3D version. Electrons packed into the thinnest-ever layer show distinctive characteristics apart from being in a "loose net".
