A process important to black holes and supernovas has for the first time been demonstrated in a laboratory.

The use of blockchain technology as a communication tool for a team of robots could provide security and safeguard against deception, according to a new study. The research may also have applications in cities where multirobot systems of self-driving cars are delivering goods and moving people across town.

Scientists and engineers have created a hydrogel tablet that can rapidly purify contaminated water. One tablet can disinfect a liter of river water and make it suitable for drinking in an hour or less.

To understand the biological underpinnings of skin and hair pigmentation and related diseases such as albinism or melanoma, scientists and doctors need quantitative, three-dimensional information about the architecture, content and location of pigment cells. Researchers have developed a new technique that allows scientists to visualize every cell containing melanin pigment in 3D, in whole...

New research examines psychological interventions for the treatment of chronic pain, including the gap between the evidence of the effectiveness of several psychological interventions and their availability and use in treatment.

A new analysis has integrated findings from 134 studies of the impact of color-coded nutrition labels and warnings found on the front of some food packaging, indicating that these labels do indeed appear to encourage more healthful purchases.

The period after hospital discharge is a high-risk time for people who use illicit opioids such as heroin, according to new research. Fatal opioid overdoses are four times more likely in the first two days after hospital discharge than at other times, and people who use illicit drugs need extra support when being discharged from hospital.

Living with a food allergy can greatly impact a child's everyday life -- from limiting participation in social activities to being treated differently by peers. While previous research indicates many kids experience food allergy-related bullying, a new study found that offering kids with food allergies a multi-question assessment gives a more accurate picture of the size and scope of the problem.

Women with undiagnosed endometriosis will have difficulty falling pregnant without IVF, according to a new study.

Cementing waterhemp's reputation as a hard-to-kill weed in corn and soybean production systems, researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized.

At the heart of planets, extreme states are to be found: temperatures of thousands of degrees, pressures a million times greater than atmospheric pressure. They can therefore only be explored directly to a limited extent -- which is why the expert community is trying to use sophisticated experiments to recreate equivalent extreme conditions. Researchers have adapted an established measurement...

A new study gives insight into how limb development evolved in vertebrates. The findings identify a gene that plays a central role in the evolution of limb development in vertebrates. By manipulating this gene in mice, researchers were able to activate an ancestral form of limb development seen in early tetrapods (four-legged vertebrates).

Researchers studying two solar parks, situated in arid locations, found they produced 'cool islands' extending around 700 meters from the solar park boundaries. The temperature of surrounding land surface was reduced by up to 2.3 degrees at 100 meters away from the solar park, with the cooling effects reducing exponentially to 700 meters. This new discovery is important as it shows the solar park...

Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon -- widespread blooms of toxic algae -- could become more commonplace, potentially threatening a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms (HABs) of the toxic algae...

Electrical engineers have discovered that changing the physical shape of a class of materials commonly used in electronics can extend their use into the visible and ultraviolet parts of the electromagnetic spectrum. Already commercially used in detectors, lenses and optical fibers, chalcogenide glasses may now find a home in applications such as underwater communications, environmental monitoring...

Scientists have made a path-breaking discovery in strontium ruthenate -- with potential for new applications in quantum electronics.

It is still elusive to what extent interactions between different cell types of the heart influence the normal heart rhythm and possibly trigger life-threatening arrhythmias. A new measurement method combines optical and electrical recording of cardiac ventricular activation which, in conjunction with optogenetics, will permit finding comprehensive answers to these questions.

Researchers developed a fully-integrated robotic arm that fuses visual data from a camera and radio frequency (RF) information from an antenna to find and retrieve object, even when they are buried under a pile and fully out of view.

To prevent the spread of COVID-19 indoors, the two meters physical distancing guideline is not enough without masks, according to researchers. However, wearing a mask indoors can reduce the contamination range of airborne particles by about 67 percent.

The findings shed new light on the root causes of this disease, which leads to the degeneration of neurons in midlife.

Chemists find manganese far superior to silver and cerium as a way to make building blocks for drug design and manufacture.

Active genes do not form clusters and share resources during early development in the fruit fly, according to a new study.

As far back as ancient Rome, spider silk has been used as a remedy to treat everything from skin lesions to warts. In the past, doctors have covered open wounds in cobwebs or advised patients to place cocoons on infected teeth. In modern times, however, the literature contains conflicting reports of whether or not spider silk has antimicrobial properties. Researchers have now revisited these old...

Researchers have discovered a brain mechanism that enables mice to override their instincts based on previous experience.
