A new study by Dana-Farber Cancer Institute researchers has given scientists their first look at the genomic landscape of tumors that have grown resistant to drugs targeting the abnormal KRASG12C protein. Their work shows that, far from adopting a common route to becoming resistant, the cells take a strikingly diverse set of avenues, often several at a time.
Organic solar elements with the self-assembling molecular-thin layer (SAM) of hole-transporting material, the technology, which was used in producing a record-breaking tandem solar cell, achieved 18.4 power conversion efficiency. The invention of Lithuanian chemists working at Kaunas University of Technology (KTU), commercialized by several global companies proved versatile and applicable to different solar technologies.
What do pipes and anchors have to do with storing energy? More than you might think! A new IIASA-led study explored the potential of a lesser known, but promising sustainable energy storage system called Buoyancy Energy Storage.
Psycholinguists from the HSE Center for Language and Brain, in collaboration with researchers from the City University of New York and the University of Stuttgart, investigated how reading in Russian varies among different groups of readers. The authors used a novel method in bilingualism research -comparison of the eye-movement sequences (scanpaths) in adult native speakers of Russian, Russian-speaking children, and adult bilinguals with different levels of Russian proficiency.
SAN ANTONIO, June 23, 2021 - A typical Western high-fat diet can increase the risk of painful disorders common in people with conditions such as diabetes or obesity, according to a groundbreaking paper authored by a team led by The University of Texas Health Science Center at San Antonio, also referred to as UT Health San Antonio.
Only 1 in 10 older adults in a large national survey who were found to have cognitive impairment consistent with dementia reported a formal medical diagnosis of the condition.
Researchers at the University of Michigan, North Dakota State University and Ohio University used data from the Health and Retirement Study to develop a nationally representative sample of roughly 6 million Americans age 65 or older. They found that 91% of people with cognitive impairment consistent with dementia did not report a formal medical diagnosis of dementia or Alzheimer's disease.
WACO, Texas (June 23, 2021) - When an organization supports its employees who choose to adopt children, the employees, their families, the adopted children and the organization itself experience positive benefits and outcomes, according to new research from Baylor University.
WOODS HOLE, Mass. -- It's cold in the depths of the world's oceans; most of the seafloor is at a chilly 4°C. Not so the seafloor of Guaymas Basin in the Gulf of California. Here, tectonic plates drift apart and heat from Earth's interior can rise up -- so far up that it bakes large areas of the seafloor sediments, turning buried organic matter into methane and other energy-rich compounds.
Rainfall associated with the Intertropical Convergence Zone (ITCZ), the belt of converging trade winds and rising air that encircles the Earth near the Equator, affects the food and water security of approximately 1 billion people worldwide. They include about 11% of the Brazilian population, concentrated in four states of the Northeast region – Rio Grande do Norte, Ceará, Piauí, and Maranhão.
Dietary protein is needed to supply essential amino acids for the synthesis of the structural and functional components of living cells. Thus, food protein quantity and quality are both essential for good health. The 2020-2025 Dietary Guidelines for Americans (DGAs) published an "ounce equivalents" recommendation to help consumers meet protein requirements with a variety of protein food sources.
There is a race going on high in the atmosphere above the Arctic, and the ozone layer that protects Earth from damaging ultraviolet (UV) radiation will lose the race if greenhouse gas emissions aren't reduced quickly enough.
Meningiomas, which originate in the meninges surrounding the brain, are the most common type of benign brain tumours. The primary treatment for meningiomas is neurosurgery. Since the risks associated with surgical treatment increase as people get older and develop other diseases, over 80-year-old patients with brain tumours are not operated on almost anywhere in the world.
Acrylamide is a toxic chemical compound that affects the nervous system. Not only is it widely used in industries such as paper production, plastics, and wastewater management, but it is also a byproduct of commonly used food processing methods, which makes human exposure to acrylamide inevitable. Therefore, many studies have focused on understanding the toxic effects of acrylamide and our body's response to them. Generally, in response to toxicity, the body's cells release protective factors and antioxidants to remedy the damage. This response is activated by various cellular machinery.
Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can track changes in the spectrum of the light by simple and extremely fast polarization measurements. The method opens new possibilities to measure spectral changes on a nanosecond time scale over the entire colour spectrum of light.
(BOSTON) - Research collaborators from the VA, Boston University, and the Concussion Legacy Foundation (CLF) published an inspiring new report today, "1,000 Reasons for Hope," which exclusively details the first 1,000 brain donors studied at the VA-BU-CLF Brain Bank since 2008 and how they have advanced research on concussions and CTE. The report also explains how the next 1,000 brain donors will answer critical questions that take us closer to preventing, diagnosing, and treating CTE, as well as the long-term consequences of concussion and traumatic brain injury.
