Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus 'package up' their genetic code, allowing them to infect cells.
The findings, published in the journal PLOS Pathogens by a team from the Universities of York and Leeds, open up the possibility that drugs or anti-viral agents can be developed that would stop such infections.
With the Proof of Concept funding line, the ERC grants recipients of ERC frontier research funds (Starting, Consolidator, Advanced or Synergy grants) with 150.000 Euro to develop promising ideas with commercial or societal potential to the proof of concept stage. With this funding, Olaf Groß and his team in the Metabolism and Inflammation Group at the Institute of Neuropathology of the Medical Center - University of Freiburg will test whether a new class of immune activating drugs they discovered can boost the effectiveness of cancer immunotherapies or vaccines against infectious diseases.
CHAMPAIGN, Ill. -- For years, researchers have worked to repurpose excess atmospheric carbon dioxide into new chemicals, fuels and other products traditionally made from hydrocarbons harvested from fossil fuels. The recent push to mitigate the climactic effects of greenhouse gases in the atmosphere has chemists on their toes to find the most efficient means possible. A new study introduces an electrochemical reaction, enhanced by polymers, to improve CO2-to-ethylene conversion efficiency over previous attempts.
Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".
Russian researchers have proposed a new method for synthesizing high-quality graphene nanoribbons -- a material with potential for applications in flexible electronics, solar cells, LEDs, lasers, and more. Presented in The Journal of Physical Chemistry C, the original approach to chemical vapor deposition, offers a higher yield at a lower cost, compared with the currently used nanoribbon self-assembly on noble metal substrates.
Moms are not more likely than other women to support gun control efforts. In fact, a new study finds that parenthood doesn't have a substantial effect on the gun control views of men or women.
"Everybody 'knows' that moms are more politically liberal on gun control issues," says Steven Greene, corresponding author of the study and a professor of political science at North Carolina State University. "We wanted to know if that's actually true. And, as it turns out, it's not true - which was surprising."
Lithium-ion batteries are critical for modern life, from powering our laptops and cell phones to those new holiday toys. But there is a safety risk - the batteries can catch fire.
Zinc-based aqueous batteries avoid the fire hazard by using a water-based electrolyte instead of the conventional chemical solvent. However, uncontrolled dendrite growth limits their ability to provide the high performance and long life needed for practical applications.
WASHINGTON -- As LEDs replace traditional lighting systems, they bring more smart capabilities to everyday lighting. While you might use your smartphone to dim LED lighting at home, researchers have taken this further by tapping into dynamically controlled LEDs to create a simple illumination system for 3D imaging.
Would you like to capture a chemical transformation inside a cell live? Or maybe revolutionize microchips' production by printing paths in a layer that has a thickness of just 100 nanometers? These and many other goals can now be achieved with the latest femtosecond laser created by a team of scientists led by Dr. Yuriy Stepanenko.
BAME parliamentary candidates not picked to fight 'winnable seats' in areas with less tolerance towa
The study found a "systematic and quantifiable pattern" of political parties officers opting against fielding minority candidates where they perceive that their non-white appearance might prevent a win. This includes constituencies already held by the party, and those within reach, requiring just a small swing in the vote to change hands.
HOUSTON - (Jan. 11, 2021) - Rice University engineers hope to make life better for those with replacement joints by modeling how artificial hips are likely to rub them the wrong way.
The computational study by the Brown School of Engineering lab of mechanical engineer Fred Higgs simulates and tracks how hips evolve, uniquely incorporating fluid dynamics and roughness of the joint surfaces as well as factors clinicians typically use to predict how well implants will stand up over their expected 15-year lifetime.
In most animal species, if a major artery is cut off from the heart, the animal will struggle to survive. The same can be said for many of our critical infrastructure systems, such as electric power, water and communications. They are networked systems with vulnerable connections.
This vulnerability was on display in September 2017 when Hurricane Maria wrecked Puerto Rico's electric power grid, leaving almost all of the island's 3.3 million people without electricity. The months-long blackout that followed was the worst in U.S. history.
HOUSTON - (Jan. 11, 2021) - A sweet new process is making sour more practical.
Rice University engineers are turning carbon monoxide directly into acetic acid -- the widely used chemical agent that gives vinegar its tang -- with a continuous catalytic reactor that can use renewable electricity efficiently to turn out a highly purified product.
PHILADELPHIA -- (Jan. 11, 2020) -- Mutations that inactivate the ARID1A gene in ovarian cancer increase utilization of the glutamine amino acid making cancer cells dependent on glutamine metabolism, according to a study by The Wistar Institute published online in Nature Cancer. Researchers also showed that pharmacologic inhibition of glutamine metabolism may represent an effective therapeutic strategy for ARID1A-mutant ovarian cancer.
Scientists crafting a nickel-based catalyst used in making hydrogen fuel built it one atomic layer at a time to gain full control over its chemical properties. But the finished material didn't behave as they expected: As one version of the catalyst went about its work, the top-most layer of atoms rearranged to form a new pattern, as if the square tiles that cover a floor had suddenly changed to hexagons.
