Subtle memory deficits are common in normal aging as well as Alzheimer disease (AD), the leading cause of dementia in older adults. This makes AD difficult to diagnose in its early stages. As there is currently no effective treatment to slow or stop the progression of AD, it is important to identify early pathological brain
Converting the tough fibers and complex sugars in plants into biofuels and other products could be humanity’s ticket to smarter materials, better medicines, and a petroleum-free, sustainable future. Hoping to discover new and improved ways of processing plant material for industrial purposes, scientists like Michelle O’Malley at UC Santa Barbara and the Joint BioEnergy Institute have been studying the gut microbiomes of the planet’s most prolific herbivores: ruminant animals such as goats.
The prevalence of anxiety disorders, already the most common mental illness in many countries, including the US, has surged during the novel coronavirus pandemic. A new study provides evidence that taking care of our gut microbiome may help mitigate some of that anxiety.
To better understand the unique reproductive biology of tsetse flies, which are carriers of the parasites that cause a deadly infection known as African sleeping sickness, researchers explored the intact organs and tissues of tsetse flies using a powerful 3D X-ray imaging technique at Berkeley Lab’s Advanced Light Source.
A test developed by Berkeley Lab scientists can quickly and easily detect whether sperm cells are carrying chromosomal defects, an advance that will help men who have undergone cancer treatment father healthy children.
A team of biologists who banded together to support COVID-19 science determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells. The structural map – which is now published in the journal PNAS, but has been open-access for the scientific community since August – has laid the groundwork for new antiviral treatments and enabled further investigations into how the newly emerged virus ravages the human body.
Researchers from Berkeley Lab and Los Alamos National Laboratory have developed new methods for the large-scale production, purification, and use of the radioisotope cerium-134, which could serve as a PET imaging radioisotope for a highly targeted cancer treatment known as alpha-particle therapy.
A new approach for studying phages-bacteria interactions will help scientists study the intricate offensive and defensive chemical tactics used by parasite and host. These microscopic battles have implications for medicine development, agricultural research, and climate science.
Scientists have determined the structure of a unique enzyme, produced by a species of methane-eating bacteria, that converts the greenhouse gas into methanol – a highly versatile liquid fuel and industrial product ingredient.
Scientists from the DOE Joint Genome Institute and DOE Systems Biology Knowledgebase have launched a public database of 52,515 microbial draft genomes generated from environmental samples collected around the world. The new resource, known as the Genomes from Earth’s Microbiomes (GEM) catalog, provides extensive insight into the many types of microbes that are impossible to grow in a lab, and expands the known diversity of bacteria and archaea by 44%.
