Wildlife advocates and environmental groups have announced that they are challenging the removal of federal protections for gray wolves across most of the U.S.
Groundbreaking science is often the result of true collaboration, with researchers in a variety of fields, viewpoints and experiences coming together in a unique way. One such effort by Clemson University researchers has led to a discovery that could change the way the science of thermoelectrics moves forward.
Twitter's impact is not limited to news, sports and political opinions.
Gender discrimination continues to plague organizations, and "gig economy" businesses, which have thrived over the last decade, are not immune, according to new research from the University of Notre Dame.
When families of banded mongooses prepare to fight, they form battle lines.
Coral reefs are vibrant communities that host a quarter of all species in the ocean and are indirectly crucial to the survival of the rest. But they are slowly dying—some estimates say 30 to 50 percent of reefs have been lost—due to climate change.
A new study reveals the damage that a nuclear war might take on wild-caught seafood around the world, from salmon and tuna to the shrimp in shrimp cocktails.
An international research project has used gene-editing technology to examine the heat tolerance of Great Barrier Reef coral with the results set to guide efforts in combatting the effects of climate change.
Today, the lakes around Cape Town are brimming with water, but it was only a few years ago that South Africa's second-most populous city made global headlines as a multi-year drought depleted its reservoirs, impacting millions of people. That kind of extreme event may become the norm, researchers now warn.
A new study of kindergarteners in one Midwestern state identified seven different pathways the children took in their early education and care before arriving at school.
Found in more than 60 countries, cruciferous clubroot disease is one of the most destructive plant diseases, causing so-called tumors on the roots of Brassicaceae crops and resulting in huge yield losses annually. The causal agent of this disease, Plasmodiophora brassicae, was first discovered by Russian biologist M. S. Woronin in 1878. Despite this early discovery, the life history of the...
A main cable that supports the Arecibo Observatory broke Friday at 7:39 p.m. Puerto Rico time.
In Japan, the proportion of the population who are single has increased dramatically in the past three decades. In 2015, one in four women and one in three men in their 30s were single, and half of the singles say they are not interested in heterosexual relationships. Public health experts at the University of Tokyo found that those who are disinterested in relationships are more likely to have...
Sometimes combinations of different things produce effects that no one expects, such as when completely new properties appear that the two combined parts do not have on their own. Dr. Libor Šmejkal from Johannes Gutenberg University Mainz (JGU) found such an unexpected property: He combined antiferromagnetic substances with non-magnetic atoms and found that, contrary to the current doctrine, a...
When and how did the first animals appear? Science has long sought an answer to this question. Uppsala University researchers and colleagues in Denmark have now jointly found, in Greenland, embryo-like microfossils up to 570 million years old, revealing that organisms of this type were dispersed throughout the world. The study is published in Communications Biology.
Bacteria are considered to be true experts in survival. Their rapid adaptive response to changing environmental conditions is based, among other things, on two competing signaling molecules. As the 'Yin and Yang' of metabolic control they decide on the lifestyle of bacteria, as reported by researchers from the University of Basel. The new findings also play a role in the context of bacterial...
The transition to remote learning coupled with an unequal distribution of second-shift responsibilities has placed teachers who are also mothers under immense stress, according to new University at Buffalo research.
Bacteria are single-celled organisms that are essential to human health, both in our environment and inside our own bodies. However, certain bacterial species can make us sick.
As agriculture in the United States evolves, it's becoming more intensive and less complex. That means larger fields, more cropland and less crop diversity with fewer crops in rotation.
The transition to middle school is undeniably tough for many sixth-graders, even in the best of times. Mounting academic demands, along with changes in peer dynamics and the onset of puberty, result in a predictable and sometimes irreversible slump in academic performance.
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Stony Brook University (SBU), the Materials Project at DOE's Lawrence Berkeley National Laboratory (Berkeley Lab), the University of California, Berkeley, and European collaborators have developed a new way to decipher the atomic-level structure of materials based on data gleaned from ground-up powder samples. They...
ITMO researchers have created a surface that can turn normal glass into a smart surface. This technology can be used in the production of AR screens that equip users with additional information about what is happening around. The surface will also be able to convert solar energy into electricity. The research has been published in Laser & Photonics Reviews.
As the icy, ocean-filled moon Europa orbits Jupiter, it withstands a relentless pummeling of radiation. Jupiter zaps Europa's surface night and day with electrons and other particles, bathing it in high-energy radiation. But as these particles pound the moon's surface, they may also be doing something otherworldly: making Europa glow in the dark.
The treatment of seawater, including its large-scale desalination, is a major challenge for our society. Reverse osmosis is one of the most widely used techniques for the desalination of water. Some of the membranes currently used are artificial channels of water inserted into lipid layers. But their large-scale performance is not satisfactory under real osmotic pressure and salinity conditions.
