An international collaboration involving European, Israeli, and US scientists realize for the first time strong and directionally dependent interactions in quantum liquids of excitons, which contrasts with the spatial isotropy of the coupling between charged particles. This spatial anisotropy affects the way particles arrange themselves in space and opens routes to artificially created exotic states of matter. The results were published in Physical Review X.

In the latest issue of the journal Nature, Army researchers and the University of Maryland demonstrate a transformative step in battery technology with the identification of a new cathode chemistry.

Would you trust a robot to diagnose your cancer? According to researchers at Penn State, people with high confidence in machine performance and also in their own technological capabilities are more likely to accept and use digital healthcare services and providers.

In order for self-driving cars to hit the streets, more people may need to concede that machines can outperform humans, at least in some tasks, according to Penn State researchers.

An article in the most recent edition of the journal Weed Science shows that cover crops can play an important role in slowing the development of herbicide-resistant weeds.

Not everyone fears our machine overlords. In fact, according to Penn State researchers, when it comes to private information and access to financial data, people tend to trust machines more than people, which could lead to both positive and negative online behaviors.

Civil status, education, and income are factors shown to be clearly associated with duration of survival after a bypass operation. A postoperative patient aged 60 with a spouse or cohabiting partner, high educational attainment, and high income has a median life expectancy five years longer than a corresponding person with no live-in partner, a low education level, and low income.

After receiving a kidney transplant, children may experience worrisome quality-of-life changes that underscore the importance of screening transplant recipients for psychosocial function, according to Children's research presented during the 10th Congress of the International Pediatric Transplant Association.

Collaborating scientists at the US Department of Energy's Ames Laboratory, Brookhaven National Laboratory, and Princeton University have discovered a new layered ferromagnetic semiconductor, a rare type of material that holds great promise for next-generation electronic technologies.

A new study led by VCU researchers finds young adults with a history of childhood abuse or neglect are more prone to using e-cigarettes during the transition to adulthood.

Tweaking the design of microring sensors enhances their sensitivity without adding more implementation complexity.

Chelsea Manning was released from a Virginia jail on May 9, 2019 after 2 months after being held on civil contempt charges forefusing to testify to a grand jury investigating WikiLeaks. She was released because the grand jury's term expired. … Click to Continue »

(BfR Federal Institute for Risk Assessment) Using the slogan 'EU and My Food' as part of a new campaign, the European Food Safety Authority (EFSA) presents the food safety system in the EU. Its standards are the highest in an international comparison. With the initiative, EFSA is highlighting the areas of food production and processing, livestock farming, environmental protection and nature conservation.

The general public largely views the use of cognitive enhancers such as Adderall as an acceptable practice when used by adults in the workplace, suggests a new study from Penn Medicine neurologists, which published this week in AJOB Neuroscience.

Multiple sclerosis (MS) is an autoimmune disease. The defense system that usually protects patients from external aggression turns on its own cells and attacks them for reasons that are not yet known. Scientists from the Institut Pasteur have shown that ancient viruses are involved in the acute inflammatory defense response that may contribute to the disease.

A new therapy to re-engage the heart's natural electrical pathways -- instead of bypassing them -- could mean more treatment options for heart failure patients who also suffer from electrical disturbances, such as arrhythmias, according to research led by the University of Chicago Medicine.

Probiotics are increasingly being researched and marketed as functional ingredients to enhance health. With the aim of bringing consumers certainty about what's in their probiotic product, an expert opinion paper was recently published in the journal Frontiers in Microbiology that provides recommendations to the probiotics industry on standards and ways to communicate quality to end-users.

Astronomers map the substance aluminum monoxide (AlO) in a cloud around a distant young star -- Origin Source I. The finding clarifies some important details about how our solar system, and ultimately we, came to be. The cloud's limited distribution suggests AlO gas rapidly condenses to solid grains, which hints at what an early stage of our solar evolution looked like.

Thanks to an innovative system of magnetic microcapsule separation, the Nanobiocel-CIBER BNN research group of the UPV/EHU-University of the Basque Country in collaboration with the BIOMICS group, also of the UPV/EHU, has managed to reduce the volume of microcapsule implants containing insulin-producing pancreatic cells by nearly 80%. That way, the medical complications arising out of implanting large volumes of microcapsules are reduced and the treatment of type 1 diabetes mellitus is improved.

South Korea and southern-central Japan are frequently affected by extreme heat, and the extreme heat in these two regions tend to occur simultaneously. A scientific collaboration of climatologists examined the large-scale circulation leading to the concurrent extreme heat over South Korea and southern-central Japan.

Kyoto University researchers find that 'waves' of Hes1 and Ascl1 gene expression control the quiescent and active state of adult neural stem cells. Hes1 expression promotes quiescence and suppresses Ascl1, and knocking out Hes1 increases Ascl1 expression and subsequent adult neural stem cell activation.

A report describes the main features of the recently published World Ocean Experiment-Argo Global Hydrographic Climatology. This climatology is based on profile data from ships, Argo floats, and sensors attached to marine mammals. As an important deviation from the widely used climatologies produced previously by the National Oceanographic Data Center, the spatial interpolation was performed on local potential density surfaces, so that no 'artificial water masses' were created.

A research team led by Associate Professor Tomoaki Mashimo at Toyohashi University of Technology has successfully developed a leech-shaped robot, 'LEeCH,' which can climb vertical walls. LEeCH is capable of elongating and bending its body without any constraints; just like a leech. Thanks to its flexible body structure and the suction cups, the robot has successfully climbed a vertical wall and even reached to the other side of the wall.

Researchers from the University of Helsinki, Finland, have discovered a chink in the armor of the tumor cells of glioblastoma, a lethal brain cancer. Alongside the finding, the researchers also came up with a method for attacking this vulnerability. The results gained in experiments conducted with cell cultures and a mouse model are promising.
