Medical Xpress / Common food preservatives linked to high blood pressure and heart disease
Eating foods that contain common preservative food additives may increase the risks of high blood pressure and cardiovascular disease, according to research published in the European Heart Journal.
Medical Xpress / Mental disorders have nearly doubled since 1990, now affecting 1.2 billion people worldwide
Nearly 1.2 billion people worldwide are living with a mental disorder, nearly double the number recorded in 1990. According to a new study, this stark rise has placed mental disorders as the leading cause of disability globally, ...
Phys.org / Wildlife is watching us, too—and changing behavior in response
A new large-scale study led by a research team from the Yale Center for Biodiversity and Global Change has found that wildlife responds not only to how humans reshape their habitats, but also to the simple presence of humans—and ...
Medical Xpress / Efforts to understand the nation's drugged driving problem stall under Trump
Two state transportation workers were replacing a sign on the shoulder of U.S. Highway 6 in western Colorado one morning when a Jeep Grand Cherokee swerved off the road and struck them.
Phys.org / We're 'green chemists'—why we think this emerging science can transform the way the world uses its resources
Society depends on chemistry far more than we consciously realize, from medicines to energy to electronics. However, chemistry is viewed with as much apprehension as gratitude, because of the pollution and health problems ...
Phys.org / Less low cloud cover lets in more heat from the sun—and may lock in centuries of sea level rise
According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems around the world.
Phys.org / Unusual nonlinear thermoelectric effect appears in chiral tellurium, confirming theoretical predictions
An unusual thermoelectric effect has been observed in the semiconductor tellurium by RIKEN physicists for the first time. This demonstration points to the potential of similar materials to be used in applications such as ...
Phys.org / Dual-atom fuel cell catalysts break single-peak rule, exposing two optima
Researchers have uncovered a new principle that could accelerate the development of cheaper and more efficient fuel cells by revealing how dual-atom catalysts behave during a key energy conversion reaction. The study, led ...
Tech Xplore / Perovskite/silicon tandem solar cells reach 32.89% certified efficiency with peak-selective passivation strategy
A team of Chinese scientists has developed a new passivation strategy that significantly improves both the efficiency and operational stability of perovskite/silicon tandem solar cells. The study has been published in the ...
Medical Xpress / Early warning signs: Poor grip strength linked to greater odds of developing depression
Handgrip strength is the maximum force a person can apply with their hand, and it is often used as a proxy for overall muscular strength, functional capacity, and aging. Scientists have found that it can also be an indicator ...
Phys.org / Extraterrestrial life may be slipping past space missions, astrobiologists warn
Suppose there are signs of extraterrestrial life and we have not yet been able to detect them. What does that mean? In Nature Astronomy, researchers discuss the consequences of these so-called false-negative results. "We ...
Tech Xplore / Novel origami pattern turns flat sheets into load-bearing 3D technology
McGill University researchers have discovered a new way to fold flat sheets into smooth, curved shells that can switch from floppy and flexible to stiff and load-bearing on demand. By designing a special origami pattern and ...
