Although U.S. court documents are publicly available online, they sit behind expensive paywalls inside a difficult-to-navigate database.
Scientists at Stanford University have discovered a surprising shift in the Arctic Ocean. Exploding blooms of phytoplankton, the tiny algae at the base of a food web topped by whales and polar bears, have drastically altered the Arctic's ability to transform atmospheric carbon into living matter. Over the past decade, the surge has replaced sea ice loss as the biggest driver of changes in uptake...
The CRISPR system is a powerful tool for the targeted editing of genomes, with significant therapeutic potential, but runs the risk of inappropriately editing "off-target" sites. However, a new study publishing July 9, 2020 in the open-access journal PLOS Biology by Feng Gu of Wenzhou Medical University, China, and colleagues, shows that mutating the enzyme at the heart of the CRISPR gene editing...
A new study might explain why humans register some tastes more quickly than others, potentially due to each flavor's molecular size. The research also provided explanation as to why humans register taste more quickly when food or drink moves over their tongues quickly, as compared to when they are held in their mouth steadily.
Bats carry many viruses, including COVID-19, without becoming ill. Biologists are studying the immune system of bats to find potential ways to 'mimic' that system in humans.
Cornell researchers including Fenghua Hu, associate professor in the Department of Molecular Biology and Genetics and member of the Weill Institute for Cell and Molecular Biology, are taking a closer look at the factors that cause Alzheimer's, FTLD and similar diseases. Hu's latest study, ''A role of the frontotemporal lobar degeneration risk factor TMEM106B in myelination,'' was published June 23...
An international team of researchers has identified a chain of events that matures the sperm and triggers their motility. The findings have implications for diagnostic and therapeutic research in male infertility and male contraceptive development.
Living close to natural green space can mitigate some of the changes in infant gut bacteria associated with formula feeding, according to new research.
A new paper examines the economics of an aquaculture industry of the future that is simultaneously environmentally sustainable and nutritious for the nearly 1 billion people worldwide who depend on it.
There is growing evidence that another 'pandemic' has been infecting bees around the world for the past two decades, and is spreading: a fungal pathogen known as Nosema.
Microbes found deeper in the ocean are believed to have slow population turnover rates and low amounts of available energy. But a new examination of microbial communities found deeper in seafloor sediments and around hydrocarbon seepage sites has found they have more energy available and a higher population turnover. The deeper sediments in the seepages are most likely heavily impacted by the...
Following U.S. students across five summers between grades 1 and 6, a little more than half (52 percent) experienced learning losses in all five summers, according to a large national study. Students in this group lost an average of 39 percent of their total school year gains during each summer.
The general functions of lymphatic vessels in fluid transport and immunosurveillance are well recognized. However, accumulating evidence indicates that lymphatic vessels play active and versatile roles in a tissue- and organ-specific manner during homeostasis and in multiple disease processes. This Review discusses recent advances to understand previously unidentified functions of adult mammalian...
Reversing brain aging may be possible through systemic interventions such as exercise. We found that administration of circulating blood factors in plasma from exercised aged mice transferred the effects of exercise on adult neurogenesis and cognition to sedentary aged mice. Plasma concentrations of glycosylphosphatidylinositol (GPI)–specific phospholipase D1 (Gpld1), a GPI-degrading enzyme...
Historically, sea ice loss in the Arctic Ocean has promoted increased phytoplankton primary production because of the greater open water area and a longer growing season. However, debate remains about whether primary production will continue to rise should sea ice decline further. Using an ocean color algorithm parameterized for the Arctic Ocean, we show that primary production increased by 57%...
