A group of trees that grow fast, live long lives and reproduce slowly account for the bulk of the biomass--and carbon storage--in some tropical rainforests, a team of scientists says in a paper published this week in the journal Science. The finding that these trees, called long-lived pioneers, play a much larger role in carbon storage than previously thought may have implications in efforts to preserve forests as a strategy to fight climate change.
Leipzig / Panama City. Tropical forests are a hotspot of biodiversity. Against the backdrop of climate change, their protection plays a special role and it is important to predict how such diverse forests may change over decades and even centuries. This is exactly what researchers at the German Centre for Integrative Biodiversity Research (iDiv), the University of Leipzig (UL) and other international research institutions have achieved. Their results have been published in the scientific journal Science.
Researchers at the University of North Carolina at Chapel Hill made a one-way street for electrons that may unlock the ability for devices to process ultra-high-speed wireless data and simultaneously harvest energy for power. The researchers did this by shaping silicon on a microscopic scale to create a funnel, or "ratchet," for electrons.
Four fossilized monkey teeth discovered deep in the Peruvian Amazon provide new evidence that more than one group of ancient primates journeyed across the Atlantic Ocean from Africa, according to new USC research just published in the journal Science.
The Journal of Clinical Oncology reports that a subgroup of women on chemotherapy in the landmark TAILORx breast cancer treatment trial had an early and abrupt cognitive decline at three and six months following treatment, which leveled off at 12 and 36 months. The women received chemotherapy plus hormone therapy following surgery, to prevent the disease from returning. The publication also reports the loss of cognition in women who received hormone therapy alone.
PITTSBURGH, April 9, 2020 - A novel clinical trial developed by researchers at the University of Pittsburgh School of Medicine launched today at UPMC to address one of the most important debates during the COVID-19 pandemic: How should doctors decide between quickly adopting new therapies, such as the anti-malarial drug hydroxychloroquine, and waiting until they are tested in longer clinical trials?
Liquid metals and alloys have exceptional properties that make them suitable for electrical energy storage and generation applications.
Low-melting point gallium-based liquid metals are used as heat exchange fluids for cooling integrated electronics and in the manufacture of flexible and reconfigurable electronic devices and soft robotics.
CHAMPAIGN, Ill. -- A multidisciplinary team of researchers at the University of Illinois at Urbana-Champaign has developed tiny sensors that measure oxygen transport in bovine lung tissue. The study - which establishes a new framework for observing the elusive connection between lung membranes, oxygen flow and related disease - is published in the journal Nature Communications.
In the course of every single cell division, the genetic information on the chromosomes must be distributed equally between the newly developing daughter cells. The enzyme separase plays a decisive role in this process. Susanne Hellmuth and Olaf Stemmann from the Chair of genetics at the University of Bayreuth have now discovered a previously unknown mechanism that regulates the activity of the separase. These fundamental findings add a new aspect to our current understanding of chromosome inheritance. The scientists have presented their study in the journal "Nature".
Creativity is one of humanity's most distinctive abilities and enduring mysteries. Innovative ideas and solutions have enabled our species to survive existential threats and thrive. Yet, creativity cannot be necessary for survival because many species that do not possess it have managed to flourish far longer than humans. So what drove the evolutionary development of creativity?
