Aurora, Colo. (Dec. 7, 2020) -- Children's Hospital Colorado (Children's Colorado) Center for Cancer and Blood Disorders (CCBD) announced today that a study about the manipulation of bone marrow stem cells into innate lymphoid and natural killer cells will be published in Science Immunology, a well-respected, high-impact medical journal.
Scientists at St. Jude Children's Research Hospital recently identified genetic variants in childhood cancer survivors of African ancestry that increase their risk of treatment-related heart problems. The findings, which have implications for how the health of these survivors is monitored, were published online today in Cancer Research, a journal of the American Association for Cancer Research.
Despite decades of investigation, Tibet's ancient topography and its role in climatic and biotic evolution remain speculative due to a paucity of quantitative surface height measurements through time and space, and sparse fossil records.
During the Second Tibetan Plateau Scientific Expedition in Tibet, an international research team from the Xishuangbanna Tropical Botanical Garden (XTBG) and the Institute of Vertebrate Paleontology and Paleoanthropology discovered a highly diverse fossil assemblage from the current elevation of 4,850 m in the Bangor Basin in central Tibet.
Rural central Namibia is one of the most important strongholds of the declining global cheetah population. Here, the rarest large African cat lives on privately owned farmland. A traditional conflict poses a threat to them, as they occasionally prey on cattle calves and are therefore rarely welcomed on the farms. New insights into the cheetah's spatial behaviour provide a viable solution to this human-wildlife conflict: In the core areas of male cheetah territories all local males and females frequently meet to exchange information.
In the past 20 years, Central Europe has experienced six summer heat waves and droughts. Until now, however, it was unclear what factors led to these extreme events. Researchers from two Helmholtz Centres (AWI & UFZ) have now discovered that in Central Europe, temperature and precipitation patterns in April play a vital role in determining whether or not the soils are drier than average in the following summer. If the April is too warm, with little precipitation, a large proportion of the moisture stored in the soil evaporates, making a summer drought more likely.
FOOD HABITS The assumption that an elderly widower can hardly boil an egg simply doesn't stand according to a recent University of Copenhagen study. The study reports that male seniors do cook and only blossom in the kitchen once alone. Widows appear to be less interested in cooking. The new findings can be useful for municipal elder care and suggest that changing gender roles don't just apply to younger generations.

Photo-induced electron transfer is central to numerous physical processes, for instance in the magnetization of materials. The quest to understand and control this ultrafast process has long been pursued in vain, with no answer to the question of whether electrons induce atomic motion, or vice versa.
Climate change has and will continue to induce severe increases in summer temperatures throughout Europe, especially in the Mediterranean region, where Italy stands out in terms of heat-related effects on daily mortality. In particular, the "urban heat island" effect makes it essential to understand context specific heat-health risks in cities in order to manage them with appropriate policy measures.
Over the past several decades, marine protected areas (MPAs) have emerged as a favored conservation tool. By protecting marine species and safeguarding habitat, these reserves help buffer ecosystems against natural and human-made shocks alike.
Researchers at UC Santa Barbara and the National Oceanic and Atmospheric Administration (NOAA) sought to determine how well MPAs protect fish from changes caused by marine heatwaves. These stressful events can drastically alter an ecosystem, and scientists predict they will increase in frequency and intensity as the climate warms.
Increased funding for Head Start -- the largest federally funded, early childhood development program in the United States -- is needed to support families during the COVID-19 recession and to ensure a more stable economic recovery.
After studying a decade's worth of U.S. data around the 2007-09 Great Recession, researchers from Washington University in St. Louis, University of North Texas, University of Melbourne and the Maryland Population Research Center made the recommendation in a study published Dec. 5 in the journal Family Relations.
HERSHEY, Pa. -- White blood cells are part of many immune system responses in the human body. New research shows that a specific type of those cells may cause brain cancer tissues to die -- but that's not good news, according to researchers at Penn State College of Medicine. They said that higher amounts of this tissue death have been associated with poor survival in patients with aggressive glioblastomas, a deadly type of brain cancer that is common in adults.
Chronic sleep disruption during adolescence can lead to depression in both males and females and alters stress reactivity in females, according to a new study led by University of Ottawa researchers. Their findings, published in the journal Behavioral Brain Research, are particularly relevant in the context of a pandemic, when adolescents' mental health is already under strain.
We talked to senior author Nafissa Ismail, Associate Professor at the uOttawa School of Psychology and University Research Chair in Stress and Mental Health, to learn more about the findings.
A research team led by Tao Sun, associate professor of materials science and engineering at the University of Virginia, has made two discoveries that can expand additive manufacturing in aerospace and other industries that rely on strong metal parts.
Otago researchers have found the "missing link between stress and infertility".
Published in The Journal of Neuroscience, and led by Professor Greg Anderson of the Centre for Neuroendocrinology, the research has confirmed in laboratory testing that a population of nerve cells near the base of the brain - the RFRP neurons - become active in stressful situations and then suppress the reproductive system.
The interaction between lasers and matter is at the forefront of new investigations into fundamental physics as well as forming a potential bedrock for new technological innovations. One of the initiatives spearheading this investigation is the Extreme Light Infrastructure Nuclear Physics (ELI-NP) project. Here the project's High-Power Laser System (HPLS) - the world's most powerful laser - is just one of the tools driving electron acceleration with lasers, Direct Laser Acceleration (DLA).
