How planarians can regenerate during periods of starvation
Planarians are able to survive long periods of starvation unscathed by maintaining their stem cell pool and regenerative capacity. The molecular processes behind this are not yet known. Jena researchers from the Leibniz Institute on Aging—Fritz Lip.....»»
EV virtual power plants could provide support in times of peak demand
Through virtual power plants, nearby EVs can pool together to create a grid power source by charging at off-peak times and/or discharging at peak periods......»»
Browsing herbivores increase savanna resilience to droughts, study finds
Extreme climate events pose an ever-increasing threat to savannas around the world. However, the ability of these mixed woodland-grassland ecosystems to resist periods of drought can be improved with a higher number of browsing herbivores—i.e., ani.....»»
In the Neanderthal site of Combe-Grenal, France, hunting strategies were unaffected by changing climate
Neanderthals in Combe-Grenal (France) preferred to hunt in open environments, and their hunting strategies did not alter during periods of climatic change, according to a study published in PLOS ONE by Emilie Berlioz of the CNRS/Université Toulouse.....»»
Scientists identify how a biological pathway leads stem cells to die or regenerate
A new study led by Cedars-Sinai and the University of California, San Francisco (UCSF), has determined that altering a cellular process can lead stem cells—cells from which other cells in the body develop—to die or regenerate......»»
Study shows circadian clock helps cells recover during starvation
Cells with a functioning molecular clock are better able to adapt to changes in glucose supply and can recover faster from long-term starvation, according to a study published today in eLife......»»
Ailing manatees in Florida"s Brevard County appear to have outlasted Christmas freeze
A cold spell and plunge in water temperature often mean a death sentence for manatees, but those in the Indian River—despite harsh environmental conditions and widespread starvation—survived the Christmas freeze without an uptick in the death tol.....»»
Manatees" starvation may be easing in Florida, authorities say
Manatees caught in a starvation crisis in the Indian River east of Orlando may not be as stricken as a year ago, wildlife officials said Wednesday......»»
Multidecadal oscillations not to be confused with reduced warming, says study
Over the last century, sea surface temperatures in the North Atlantic have oscillated over periods of a few decades. These oscillations have not been limited to the ocean. Corresponding variations have been observed in the Arctic sea-ice cover, in oc.....»»
Scientists describe 146 new species in 2022
During 2022, researchers at the California Academy of Sciences have added 146 new animal, plant, and fungi species to the tree of life, enriching our understanding of Earth's biodiversity and strengthening our ability to regenerate the natural world......»»
Rudolph is coping with climate change better than feared—for now
The North Pole is not what it once was. The Arctic is the area on the globe where temperatures are rising the fastest. On Svalbard, a Norwegian archipelago in the Arctic Ocean, this entails extended periods of mild weather. Precipitation comes as rai.....»»
A cheaper method to recycle activated carbon
A research group led by Prof. Lu Zhiyi at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has proposed a facile and cost-effective strategy to regenerate powdered activated carbon (PAC) by ancho.....»»
Here"s how we all used Zoom in 2022
Middle of the week is prime time as Zoom uncovers busiest periods and surprising generational divides.....»»
Lettuce arrives in Florida this week to fight feared return of manatee starvation
In a lull before a feared return to disaster, wildlife authorities said Wednesday they are about to receive truckloads of lettuce for feeding starving manatees this winter in the coastal Indian River east of Orlando......»»
Starvation shown to cause cell remodeling
Body cells burn off fat reserves when nutrient supply from food ceases. A team led by Professor Volker Haucke and Dr. Wonyul Jang from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) has now discovered a previously unknown mechanis.....»»
Insects may feel pain, says growing evidence: Here"s what this means for animal welfare laws
At least a trillion insects are killed annually for food and animal feed. Routine slaughter methods include extreme heat and cold, often preceded by starvation. By comparison, "only" around 79 billion mammals and bird livestock are slaughtered every.....»»
Florida mints radiated as peninsula sank and resurfaced during ice ages, finds study
During the ice ages of the Pleistocene, the Florida peninsula regularly grew to twice its current size as glaciers expanded near the planet's poles, only to be reduced to a series of islands as melting ice returned to the sea during warm periods. All.....»»
Finding genes to help fruit adapt to droughts
As climate change is expected to lead to more frequent periods of drought, researchers are increasingly working to make discoveries that can help plants adapt to prolonged water stress......»»
Cracking open a fossil bone reveals rapid juvenile growth in early tetrapods
The rise of tetrapods (four-limbed vertebrates) is one of the iconic evolutionary transitions preserved in the fossil record. These animals, which lived about 385 to 320 million years ago during the Devonian and Carboniferous periods of Earth's histo.....»»
Amazon selling Apple"s M1 MacBook Air for $799
Amazon has dropped the price of the 2020 M1 MacBook Air with 8GB RAM, 256GB storage, to $799, making it the lowest-cost Apple Silicon MacBook.The M1 MacBook Air has seen a 20% price drop from Amazon before, but it is always for limited periods — an.....»»
Developing alginate hydrogels that can support cell growth
Encapsulating cells—both prokaryotic and eukaryotic—allows researchers to carry out experiments in hydrated environments over prolonged periods of time. However, cell growth under these conditions can exert a lot of pressure on the encapsulating.....»»
