New research involving more than 440,000 Americans links cannabis use to increased cardiovascular risk, with occasional users showing 40% higher odds of reporting a history of stroke. The findings suggest that even infrequent marijuana use may warrant concern, although
In summer 2020, the German federal government lowered value-added tax from 19% to 16% for half a year as part of its COVID economic stimulus package. A new study, recently published in the journal Review of Economic Studies, uses survey data, data on retail purchases and an
A surprising new study reveals that mosquitoes have very different tastes in humans, with each species attracted to its own combination of skin odors, chemicals, and bacteria. The discovery challenges the idea of a universal mosquito magnet and could lead to more effective
A new study reveals that coyote populations on the Outer Banks persist despite ongoing removal programs, posing a continued threat to shore-nesting birds and protected sea turtles. The study is the first in-depth assessment of coyote populations on barrier islands and has
Life cycle assessment is used to quantify the environmental impact of products and services and forms an important basis for political decisions. However, the necessary data is always difficult to capture completely. A study by the Paul Scherrer Institute PSI now shows that
Losing a job can be a life-shattering experience. And when depression complicates a job search, unemployment can become a vicious cycle. Now, a Northwestern University–led clinical trial suggests a new intervention may break that cycle: a phone app, named DRIVEN, that combines
Scientists have uncovered fossils of a giant rodent that lived in Thailand 34 million years ago, revealing that enormous rodents evolved much earlier than previously thought. Named Yakamys sirindhornae, the ancient animal may have weighed around 66 pounds, roughly twice as much
ZonationR is a new tool that simplifies the use of Zonation to identify priority areas for biodiversity conservation. It brings all stages of the conservation planning analysis together in one automated and reproducible workflow and helps users systematically explore and
To what extent do genes influence the migratory routes of birds? The factors that determine the long-distance migrations of seabirds are not yet fully understood. Now, a study published in the journal Molecular Ecology reveals that, in the case of Cory's shearwater, an
A bizarre, heavily armored amphibian roamed the oceans 237 million years ago, despite the fact that modern amphibians cannot survive entirely in saltwater. Discovered in China, the giant salamander-sized creature may be the first known amphibian to have adapted to a fully
The oldest pair of compact quasars ever observed has been found only 900 million years after the Big Bang. Scientists say there is no theoretical explanation for how the pair of actively feeding black holes grew so massive at such an early time in the history of the universe.
Iron-sulfur clusters are ancient protein cofactors that are essential for electron transport, enzyme catalysis and photosynthesis. However, their sensitivity to oxygen and inherent instability have long hindered their practical application.
The LISA (Laser Interferometer Space Antenna) observatory, now in development, will detect gravitational waves, the tiny ripples in space-time caused by orbiting masses. Now two studies led by NASA astrophysicists show in new detail how LISA could reveal a new and unique
Contrary to what was previously believed, viruses infecting fish are not transmitted exclusively through water acting as an abiotic vector. A team of researchers from the University of Liège has demonstrated that a virus affecting European eels can spread very efficiently
Researchers from the Skoltech AI Center, together with colleagues from the Zelinsky Institute of Organic Chemistry of the Russian Academy of Sciences, ITMO University and other institutions, have published a paper in Chemical Society Reviews that examines where AI produces
Bioacoustics researcher Léa Bouffaut, at the Cornell K. Lisa Yang Center for Conservation Bioacoustics, has spent the past several years eavesdropping on the conversations of whales. But instead of using underwater microphones like other marine scientists, she listens by
Marine heat waves and anemone bleaching are altering clownfish behavior, making clownfish more defensive of their host and more aggressive toward one another, new research reveals.
Redirecting shipping traffic to avoid collisions with whale sharks has very little impact on fuel use, according to new research led by the University of Southampton published in Royal Society Open Science.
Scientists have identified a major turning point in Earth's geological history, when the processes shaping the planet's crust changed dramatically and began to resemble the plate tectonics we see today—about 2.5 billion years ago.
Disadvantaged students are less likely than their more advantaged peers with similar attainment to take and pass entrance exams for selective schools, and introducing an opt-out system for the tests would only deliver a small boost.
