A new study coordinated by the Research Group in Developmental Biology at UPF shows that during the embryonic development of the brain, the cells that are between adjacent segments detect the mechanical forces generated during morphogenesis to regulate the balance between progenitor stem cells and differentiated neurons. The study has been published in the journal Development.
Algae take up carbon dioxide (CO2) from the atmosphere and turn the carbon into biomass while releasing the oxygen back to the atmosphere. Fast algal growth during phytoplankton blooms leads to a massive transfer of carbon dioxide into algal biomass. But what happens to the carbon next?
'Predatory journals' pose a danger that could undermine the quality, integrity, and reliability of published scientific research, a new joint statement from three leading organizations, professional in medical writing and publication planning, has warned.
EAST LANSING, Mich. - What can fish teach scientists about limb regeneration? Quite a bit, as it turns out.
In the current issue of Proceedings of the National Academy of Sciences, Michigan State University scientists show that gar, a toothy, freshwater fish, can reveal many evolutionary secrets - even possible genetic blueprints for limb regeneration in people.
Japanese scientists have developed an efficient method of successfully generating hair growth in nude mice. The new method can be scaled up and therefore shows great potential for clinical applications in human hair regenerative therapy.
Their findings were published on May 9, 2019 in Biomaterials.
Imagine you are a farmer struggling to keep up with production demands because of the increasingly stressful climate. Or perhaps you are a producer of renewable energy struggling with dramatic heat and weather. With increasing temperatures, solar panels get too hot to function properly, and crops demand more water, problems that are exacerbated by drought and climate conditions.
CATONSVILLE, MD, July 29, 2019 - We've all been there... you're out to eat and in need of a refill or the check and the wait staff is nowhere to be found. It slows down business, reduces customer satisfaction and hurts the bottom line. New research in the upcoming INFORMS journal Management Science shows to counter this, restaurants should introduce tabletop technology as a demonstrated way to improve service and satisfaction.
Tiny gas-filled bubbles in the porous rock found around hot springs are thought to have played an important role in the origin of life. Temperature differences at the interface between liquid phases could therefore have initiated prebiotic chemical evolution.
LAWRENCE -- Politics have been known to put adults to sleep, but political engagement could be part of children's bedtime stories as well. Lessons about the importance of politics could be part of their early education. A new University of Kansas study analyzed political messages in the most popular picture books of the last several years to see what political messages are included and how they are presented.
Building on research results published today in JAMA Neurology showing patients with larger ischemic strokes could benefit from endovascular thrombectomy, an international, multicenter Phase III clinical trial will be starting at The University of Texas Health Science Center at Houston (UTHealth).
The trial, called SELECT2 (Optimizing Patient Selection for Endovascular Treatment in Acute Ischemic Stroke), is a randomized, controlled, open-label, assessor-blinded trial assessing efficacy and safety of thrombectomy procedure in patients with larger ischemic stroke.
Many of the consequences of climate change are well reported in the press: rising seas, more severe storms, droughts and floods, and increasing numbers of heat-related illness and deaths. Now Ian Sue Wing, a Boston University College of Arts & Sciences associate professor of earth and environment, Bas van Ruijven, a former visiting scholar at the Frederick S.
A University of Oklahoma-led study generated improved annual maps of tropical forest cover in the Brazilian Amazon in 2000-2017 and provided better characterization on the spatio-temporal dynamics of forest area, loss and gain in this region. The Amazon basin has the largest tropical forests in the world. Rapid changes in land use, climate and other human activities have resulted in substantial deforestation in the Brazilian Amazon over the past several decades.
The brain is composed of many different types of neurons, and scientists are just beginning to uncover the functional significance of this vast cellular diversity. At Baylor College of Medicine, Drs. Benjamin Arenkiel, Gary Liu and their colleagues at Baylor, the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital and Rice University studied the functional relationships between inhibitory interneurons, a type of nerve cell, and two excitatory cell types, called tufted cells and mitral cells, in the murine olfactory bulb.
DURHAM, NC -- Scientists at Duke University have identified one kind of lung cell that can hustle to repair its damaged DNA and survive an attack of the influenza A virus while other kinds of cells around it die in droves.
The finding reveals more about the battle between cells and viruses at the smallest level, and also may provide some important clues for respiratory conditions such as chronic obstructive pulmonary disease and asthma.
A collection of new studies in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences further quantifies how blueberry consumption can contribute to healthy aging.
