The targeted LHRH analog AEZS-108 alters expression of genes related to angiogenesis and development
Graphene-based heterostructures of the van der Waals class could be used to design ultra-compact and low-energy electronic devices and magnetic memories. This is what a paper published in the latest issue of the Nature Materials journal suggests. The results have shown that it is possible to perform an efficient and tunable spin-charge conversion in these structures and, for the first time, even at room temperature.
Excessive activity of an immune system gene previously linked to schizophrenia reproduces neural and behavioral aspects of the disease in mice, according to a new study publishing on January 14 in the open-access journal PLOS Biology by Ashley Comer and Alberto Cruz-Martín of Boston University and colleagues. The finding provides mechanistic support for the importance of the gene in the development of schizophrenia, and may offer a new avenue for therapy development.
Adverse outcomes from childhood exposures to lead and mercury are on the decline in the United States, likely due to decades of restrictions on the use of heavy metals, a new study finds.
Despite decreasing levels, exposure to these and other toxic chemicals, especially flame retardants and pesticides, still resulted in more than a million cases of intellectual disability in the United States between 2001 and 2016. Furthermore, as the target of significantly fewer restrictions, experts say, flame retardants and pesticides now represent the bulk of that cognitive loss.
BEER-SHEVA, Israel - January 14, 2020 - Ben-Gurion University of the Negev (BGU) researchers have developed a new nitrate sensor that will provide real-time and continuous measurement in soil to better detect water pollution and measure conditions for higher agricultural productivity.
Researchers have developed a new process that could make it much cheaper to produce biofuels such as ethanol from plant waste and reduce reliance on fossil fuels.
Their approach, featuring an ammonia-salt based solvent that rapidly turns plant fibers into sugars needed to make ethanol, works well at close to room temperature, unlike conventional processes, according to a Rutgers-led study in the journal Green Chemistry.
Human-induced climate change promotes the conditions on which wildfires depend, increasing their likelihood - according to a review of research on global climate change and wildfire risk published today.
In light of the Australian fires, scientists from the University of East Anglia (UEA), Met Office Hadley Centre, University of Exeter and Imperial College London have conducted a Rapid Response Review of 57 peer-reviewed papers published since the IPCC's Fifth Assessment Report in 2013.
Over the last few decades, machine learning has revolutionized many sectors of society, with machines learning to drive cars, identify tumors and play chess - often surpassing their human counterparts.
Now, a team of scientists based at the Okinawa Institute of Science and Technology Graduate University (OIST), the University of Munich and the CNRS at the University of Bordeaux have shown that machines can also beat theoretical physicists at their own game, solving complex problems just as accurately as scientists, but considerably faster.
If you jump out of bed too quickly, you might feel a bit light-headed.
That's because when you're lying down, gravity causes your blood to pool in the lower parts of your body rather than in your brain. Fortunately, when you stand up, within a fraction of a second, your heart begins beating faster, moving the blood to your brain and allowing you to maintain your balance.
Newton, Mass. (January 13, 2020) -- Before sharing human research data, scientists routinely strip it of personal information such as name, address, and birthdate in order to protect the privacy of their study participants. However, reporting in the journal Environmental Health Perspectives, researchers at Silent Spring Institute and their colleagues show that for environmental health studies, that might not be enough--even anonymized data can sometimes be traced back to individuals.
Maintaining long-term memories requires environmental light, according to research in fruit flies recently published in JNeurosci.
Memories begin in a temporary form, which are converted into long term memories as protein expression and brain circuits change. But, long term memories require active maintenance in order to survive the changing molecular landscape of the brain. Previous research indicates exposure to different colors of light alters memory function in humans and animals, but the role of natural lighting conditions in memory maintenance remains unknown.
Researchers have found that melanoma cells fight anti-cancer drugs by changing their internal skeleton (cytoskeleton) - opening up a new therapeutic route for combatting skin and other cancers that develop resistance to treatment.
Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keeps them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer.
Crop production in Britain will fall dramatically if climate change causes the collapse of a vital pattern of ocean currents, new research suggests.
The Atlantic Meridional Overturning Circulation (AMOC) brings heat from the tropics, making Britain warmer and wetter than it would otherwise be.
University of Exeter scientists show that, while warming Britain is expected to boost food production, if the AMOC collapses it would not just wipe out these gains but cause the "widespread cessation of arable (crop-growing) farming" across Britain.
A mysterious piece of genetic material restrains the spread of skin cancer cells, but is frequently lost as they mature, a new study finds.
Published online January 13 in Cancer Cell, the new work revolves around circular RNA, a recently described type of ribonucleic acid (RNA). Typically, DNA blueprints are converted into RNA and then into proteins with cellular functions. While most RNA are linear molecules, some form circles when their ends loop around and attach.
