An abnormal build up of carbohydrates -- sugars and starches -- in the kernels and leaves of a mutant line of corn can be traced to one misregulated gene, and that discovery offers clues about how the plant deals with stress.
Businesses sometimes align themselves with important values such as a clean environment, feminism, or racial justice, thinking it's a win-win: the value gets boosted along with the company's bottom line. But be careful, warns new research. Using these values primarily for self-interested purposes such as profit or reputation can ultimately undermine their special status and erode people's...
Scientists have developed a stable, anode-free sodium ion battery that is highly efficient, will be less expensive and is significantly smaller than a traditional lithium ion battery.
Scientists simulated the local risk of damaging or nuisance-level shaking caused by hydraulic fracturing across the Eagle Ford shale formation in Texas. The results could inform a new approach to managing human-caused earthquakes.
A study of a rare and common desert plant indicates solar development in the desert may impact rare species more. It also demonstrates the importance of taking the time to understand the ever-changing desert ecosystem before irrevocably changing it.
The importance of pollinators to ensure successful harvests and thus global food security is widely acknowledged. However, the specific pollinators for even major crops - such as cocoa - haven't yet been identified. Now an international research team has found that in fact ants and flies - but not ceratopogonid midges - appear to have a crucial role to play.
Former Florida senator Bill Nelson was sworn in Monday as head of NASA, hailing a "new day" for space exploration as the United States seeks to return to the Moon.
Throughout the history of the West, human actions have often rushed the desert—and their actions backfired. In the 1920s, the Colorado River Compact notoriously overallocated water still used today by several western states because water measurements were taken during a wet period.

Even under the most optimistic scenarios, most of the coral reef ecosystems on our planet—whether in Australia, the Maldives or the Caribbean—will have disappeared or be in very bad shape by the end of this century. That's because global warming is pushing ocean temperatures above the limit that single-cell algae, which are corals' main allies, can withstand. These algae live inside coral...
Researchers from NYU Abu Dhabi's Center for Genomics and Systems Biology have successfully sequenced the genome of previously extinct date palm varieties that lived more than 2,000 years ago. They did so using date palm seeds that were recovered from archaeological sites in the southern Levant region and radiocarbon-dated from the 4th century BCE to the 2nd century CE. The seeds were germinated to...
The idea that animals should avoid mating with relatives has been the starting point for hundreds of scientific studies performed among many species. But new research shows that there is little support for this assumption. The study provides a synthesis of 139 experimental studies in 88 species and 40 years of research, settling the debate about if and when animals should avoid inbreeding.
Single-cell RNA sequencing reveals 40 different cell types in Stylophora pistillata, a reef-building stony coral native to the Indo-Pacific oceans. The calcium carbonate skeleton of stony coral colonies are the main habitat for a huge diversity of marine species. The study has detected the presence of specialized immune cells in corals or any cnidaria. The findings will aid present and future...
Emulating the human lung airway in vitro identified the SARS-CoV2-inhibiting effects of the antimalarial drug amodiaquine, which is now in COVID-19 clinical trials.
New work unravels a longstanding mystery about the relationship between form and function in the genetic material of a diverse group of algae called dinoflagellates. The findings have implications for understanding genomic organizational principles of all organisms.
Silicon-based fiber optics are currently the best structures for high-speed, long distance transmissions, but graphene -- an all-carbon, ultra-thin and adaptable material -- could improve performance even more.
A grass commonly used to fight soil erosion has been genetically modified to successfully remove toxic chemicals left in the ground from munitions that are dangerous to human health, new research shows.

There’s nothing new about conspiracy theories, disinformation, and untruths in politics. What is new is how quickly malicious actors can spread disinformation when the world is tightly connected across social networks and internet news sites. We can give up on the problem and rely on the platforms themselves to fact-check stories or posts and screen…
In the aftermath of George Floyd's 2020 murder by former police officer Derek Chauvin, many families may find themselves actively engaging in—or uncomfortably fumbling around—discussions about race. For white parents looking to clearly communicate antiracist ideologies with their preadolescent children, a new study offers some insight.
A giant saber-toothed cat lived in North America between 5 million and 9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported today in a new study.
Belief in conspiracies about the COVID-19 pandemic increased through the early months of the U.S. outbreak among people who reported being heavy users of conservative and social media, a study by Annenberg Public Policy Center (APPC) researchers has found.
Ever look at a flatfish like a flounder or sole, with two eyes on one side of its head, and think, "How did that happen?"
Living materials, which are made by housing biological cells within a non-living matrix, have gained popularity in recent years as scientists recognize that often the most robust materials are those that mimic nature.
The human world is, increasingly, an urban one—and that means elevators. Hong Kong, the hometown of physicist Zhijie Feng (Boston University), adds new elevators at the rate of roughly 1500 every year...making vertical transport an alluring topic for quantitative research.
In recent decades, Spain has undergone rapid social changes in terms of gender equality, despite, as a result of the Franco dictatorship, starting from a more backward position than most European countries. This process is hampered by the economic downturn that began in 2008, underlining the importance of the economic context in the development of gender inequality levels. Little attention has...
California clean tech innovator Bloom Energy, with its noncombustion, low-emission fuel cells, is hardly taking the same approach to powering the planet as oil giant Chevron, but one thing the companies have in common are slick promotional campaigns defining them as environmental pioneers.
