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.
Almost a third of adult single men live with a parent. Single men are much more likely to be unemployed, financially fragile and to lack a college degree than those with a partner. They’re also likely to have lower median earnings; single men earned less in 2019 than in 1990, even adjusting for inflation. Single women, meanwhile, earn the same as they did 30 years ago, but those with...
The pipeline that leaked more than 550,000 litres of oil into the water off Southern California was split open and apparently dragged along the ocean floor, according to...
A promising method for producing and observing on Earth a process important to black holes, supernova explosions and other extreme cosmic events has been proposed by scientists at Princeton University's Department of Astrophysical Sciences, SLAC National Acceleraor Laboratory, and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The process, called quantum...
Quantitative empirical studies exploring how climatic and other environmental drivers influence migration are increasing year by year. PIK scientists have now reviewed methodological approaches used in the quantitative climate migration literature. Their review plays an important role when it comes to assessing how climatic factors influence human migration, and provides guidance to researchers...
Brian Keating was recently enjoying a stunning view of the Creston Valley from the Thompson Rim Trail when he stumbled across what he thought were ladybugs. Hundreds of...
On Sunday night, the primary source for the Wall Street Journal’s Facebook Files, an investigative series based on internal Facebook documents, revealed her identity in an episode of 60 Minutes. Frances Haugen, a former product manager at the company, says she came forward after she saw Facebook’s leadership repeatedly prioritize profit over safety. Before quitting…
American households making less than $50,000 are more likely than higher-earning families to spend the expanded child tax credit on essential expenses and tutors for their children, found a survey from the Social Policy Institute (SPI) at Washington University in St. Louis.
As dead birds wash ashore on Southern California beaches, the victims of a major oil spill, environmentalists are calling on Gov. Gavin Newsom to reduce the state's ties to the oil industry.
For some 50 years scientists have worked to harness Bloch oscillations, an exotic kind of behavior by electrons that could introduce a new field of physics—and important new technologies—much like more conventional electronic behavior has led to everything from smart watches to computers powerful enough to get us to the Moon.
If an asteroid is determined to be on an Earth-impacting trajectory, scientists typically want to stage a deflection, where the asteroid is gently nudged by a relatively small change in velocity, while keeping the bulk of the asteroid together.
Cementing waterhemp's reputation as a hard-to-kill weed in corn and soybean production systems, University of Illinois researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized.
The Nobel Prize in Physics has gone to three scientists who sought to predict the long-term evolution of a complex system such as the climate by modelling variables—weather, human actions—that create disorder within those systems.

Anyone who has followed U.S. climate policy is familiar with the cycle of bold attempts to enact climate rules that eventually sputter, followed by years of inaction. President Bill Clinton proposed an energy tax before backing away under...
When bestselling science-fiction writer Kim Stanley Robinson opened his latest novel, The Ministry for the Future, he set the scene in India, where a deadly heat dome wipes out almost the entire population of a provincial city, sowing the seed for a radical political movement to combat climate change.

A huge slick of oil stalked the California coast Tuesday as officials frantically tried to protect ecologically sensitive shorelines and investigators probed whether a ship's anchor caused a pipe breach that sent tens of thousands of gallons of crude into the waters off Orange County.
For more than two years, NASA's Deep Space Atomic Clock has been pushing the timekeeping frontiers in space. On Sept. 18, 2021, its mission came to a successful end.
Actor and director on International Space Station push ahead of Hollywood project led by Tom CruiseThe list of “firsts” in orbit under the Soviet space programme is legendary: first satellite, first dog, first man, first woman.Now another looms after Russia sent an actor and a director to the International Space Station (ISS) as part of plans to make the first film in orbit – and once again...
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...
