Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today's silicon-based electronics. Scientists have now shown that graphene can actually convert electronic signals with frequencies in the gigahertz range extremely efficiently into signals with several times higher frequency.
Scientists have developed a new technique that can determine how viruses interact with a host's own RNA. As well as providing insight into how viruses direct the host cell to create new virus particles, this technique could allow researchers to design artificial molecules capable of blocking the virus replication process and preventing the virus spreading.
Obesity and its related ailments like type 2 diabetes and fatty liver disease pose a major global health burden, but researchers report that blocking an RNA-silencing protein in the livers of mice keeps the animals from getting fat-related and diabetic conditions.
Repeated binge drinking activates genes in an area of the brain linked to addiction differently in males and females. Genes associated with hormone signaling and immune function are affected by repeated binge drinking in female mice, whereas genes associated with nerve signaling are affected in the males. These findings have implications for alcohol abuse treatment, emphasizing the importance of c
More and more data and images are generated during ocean research. In order to be able to evaluate the image data scientifically, automated procedures are necessary. Researchers have now developed a standardized workflow for sustainable marine image analysis for the first time.
The magnitude and trajectory of sea-level change during the Last Interglacial, more specifically Marine Isotope Stage (MIS) 5e, is uncertain. To date the consensus view has been that sea-level may have been six to nine meters above present sea level. However, scientists are now questioning if those sea level fluctuations are accurate.
There is currently a grand consensus of academics, policymakers and food campaign groups that "something must be done" to reduce food wastage. Malnutrition is real, but so too is the obesity crisis. But when everyone agrees, you can afford to be a little sceptical. Because food is about much more than just calories and nutrients. Food is also part of a wider cycle of products and services that we
For couples hoping for a baby via in vitro fertilization, chances have improved. A process that once took hours now takes minutes: Cornell University scientists have created a microfluidic device that quickly corrals strong and speedy sperm viable for fertilization.
Up to now, researchers have believed that birds stay at home and altruistically help raise younger siblings because this is the only way to pass on genes when you cannot breed yourself. But this idea is only partially true. A new study shows that birds benefit from being helpful because it also increases their chances of reproducing in the future.
As the planet warms, species are moving further north to climate zones which are closer in temperature to what they originally evolved in. The oceans have absorbed most of this temperature increase, and so many marine species, including commercially fished scallops, are under particular stress to migrate northwards to cooler waters.
Ever since we've had the technology, we've looked to the stars in search of alien life. It's assumed that we're looking because we want to find other life in the universe, but what if we're looking to make sure there isn't any? Read More

Cancer cells often have mutations in their DNA that can give scientists clues about how the cancer started or which treatment may be most effective. Finding these mutations can be difficult, but a new method may offer more complete, comprehensive results. A team of researchers has developed a new framework that can combine three existing methods of finding these large mutations — or structural va
The research challenges the traditional viewpoint that the simultaneous presence of stress and a corrosive environment is a requirement for SCC and demonstrates that stress and corrosion can act independently.
The magnitude and trajectory of sea-level change during the Last Interglacial, more specifically Marine Isotope Stage (MIS) 5e, is uncertain. To date the consensus view has been that sea-level may have been six to nine meters above present sea level. However, scientists at The University of New Mexico (UNM) and the University of South Florida (USF) and their international team of collaborators are
Peatlands are extremely effective at storing carbon, but an international study featuring a University of Queensland researcher has found climate change could stop that. The group investigated how peatlands — swamps and bogs with organic rich soils — have responded to climate variability between 850 BCE and 1850 CE.
UC San Francisco researchers have discovered how a mutation in a gene regulator called the TERT promoter — the third most common mutation among all human cancers and the most common mutation in the deadly brain cancer glioblastoma — confers 'immortality' on tumor cells, enabling the unchecked cell division that powers their aggressive growth.
They may start as well-intentioned efforts to calm anxiety, improve sleep or ease depression. But prescriptions for sedatives known as benzodiazepines may lead to long-term use among one in four older adults who receive them, according to new research. That's despite warnings against long-term use of these drugs, especially among older people, because they can increase the risk of car crashes, fal
An international team led by Assistant Professor Kasper Steen Pedersen, DTU Chemistry, has synthesized a novel nano material with electrical and magnetic properties making it suitable for future quantum computers and other applications in electronics.
Mitosis — how one cell divides and becomes two — is one of the fundamental processes of life. Researchers at EMBL have now produced the first interactive map of proteins that make our cells divide, allowing users to track exactly where and in which groups the proteins drive the division process forward. This first dynamic protein atlas of human cell division is published in Nature on Sept. 10, 2
Researchers at The University of Texas MD Anderson Cancer Center have shown how BRCA-associated protein 1 (BAP1) serves as a tumor suppressor gene in kidney, eye, bile duct, mesothelioma and other cancers by regulating a form of cell death called ferroptosis, opening up a potential new area of therapy research.

It was 8.45am when the Prambanan Express train from Surakarta arrived at Lempuyangan Station, Yogyakarta. My wife and I stepped out from the station and walked hurriedly to a spot under an overpass, 100 metres east of the station, where we could usually order an online taxi.
A new examination of the role of children's genomes in their education progress reveals their impact on both school league tables and how teacher performance is assessed.
Science And why you should doodle in class. All of us multitask. But psychologists have been warning us about it for decades. Some say it's harmful to productivity and others say you can't do it at all.
In human cells grown in the lab, a natural plant compound halts the overactive signaling that drives growth of uveal melanoma, a cancer of the eye, researchers report. Uveal, or ocular, melanoma arises from the layer of pigmented cells of the eye that includes the iris. Fatal in about half of the patients who develop it, the cancer represents about 3 to 5 percent of all melanoma cases. Unlike ski
EPFL scientists have mapped out the steps required to build a self-sustaining research base on Mars that would be habitable for the long term. Their work can help researchers set priorities for space programs exploring Mars as well as the solar system as a whole.
Calvin College professor of astronomy Larry Molnar made a bold announcement in 2017—he and his team had identified a binary star in the constellation Cygnus, the Swan, that was a strong candidate to merge and explode in the near future. Known by its Kepler mission number, KIC 9832227, the pair of stars is about 1800 light years from Earth and has an orbit so close that it takes just 11 hours to go
"CBS takes these allegations very seriously. Our Board of Directors is conducting a thorough investigation of these matters, which is ongoing." That was one of the several statements CBS issued on Sunday , in response to a story published that morning in The New Yorker : Ronan Farrow's follow-up to the report he had published in July , a story detailing allegations from six different women about
Prerelease hype often consumes a movie before it's even out in theaters. Trailer speculation, plot rumors, and awards-season predictions all help fuel the film-journalism industry. But even by that yardstick, the groundswell of interest in A Star Is Born , a rock musical starring Lady Gaga that's also Bradley Cooper's debut as a writer and director, has been fascinating to behold. It's rare that

Bright surface features on the dwarf planet Ceres known as faculae were first discovered by NASA's Dawn spacecraft in 2015. This mosaic of one such feature, Cerealia Facula, combines images obtained from altitudes as low as 22 miles (35 km) above Ceres' surface. The mosaic is overlain on a topography model based on images obtained during Dawn's low altitude mapping orbit (240 miles or 385 km altit
Isaac Ginis said that it is notoriously difficult to forecast hurricanes in New England. When storms move north, they develop a more complex wind structure than those remaining in the Southeast and Gulf of Mexico, their paths become more erratic, and the region's complicated topography makes predicting their movement over land especially challenging. In addition, the relatively short rivers in New
