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.....»»
Silkworms and shrimp may help regenerate damaged skin and bone
Researchers are exploring new nature-based solutions to stimulate skin and bone repair......»»
Study shows tree species have different strategies for coping with light conditions in forest understory
Scientists at the Institute of Applied Ecology of the Chinese Academy of Sciences have made a breakthrough in understanding why Korean pine trees are struggling to regenerate naturally in certain forests. These broad-leaf Korean pine forests are vita.....»»
Call of Duty: Black Ops 6’s two beta periods are on the way
Activision announced that an early access beta period will be coming at the end of August, followed by an open beta......»»
Study shows severe droughts limit Amazonian communities" access to basic services
Severe droughts in the Amazon basin over the past two decades have caused low water level periods to last around a month longer than usual, triggering profound impacts on the local population......»»
Evolutionary biologists investigate how plant cold specialists can adapt to the environment
Plant cold specialists like the spoonworts have adapted well to the cold climates of the Ice Ages. As cold and warm periods alternated, they developed a number of species that also resulted in a proliferation of the genome......»»
Modern lives are messing up menstrual cycles—earlier starts, more irregularity
Earlier and irregular periods are both linked to poor health outcomes. Enlarge / Panty liners, hygienic tampons, and sanitary pads. (credit: Getty | LOU BENOIST) People in the US are starting their menstrual cycles earli.....»»
DNA analysis reveals that Jamestown Colony residents ate dogs with Indigenous ancestry
Dogs with Indigenous ancestry were eaten during a period of starvation at Jamestown, the first English settlement in North America in the 17th century, according to new research in American Antiquity......»»
Transformation and mechanisms of climate wet/dry change on the northern Tibetan Plateau under global warming
Historical patterns of climate change can provide ways to predict future climate change. During geological history, the earth has experienced many warm periods of different time scales, such as the mid-Holocene warm period, the medieval climate anoma.....»»
Limited adaptability is making freshwater bacteria vulnerable to climate change
Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from Lake Zurich and other European lakes, researchers at the University of Zurich have uncovered specific evolut.....»»
Scientists regenerate neural pathways in mice with cells from rats
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present n.....»»
Half our colleagues suffer pain and discomfort from periods—but they"re still a taboo subject at work
Have you ever felt sick at work? Perhaps you had food poisoning or the flu. Your belly hurt, or you felt tired, making it hard to concentrate and be productive......»»
Why zebrafish can regenerate damaged heart tissue, while other fish species cannot
A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults......»»
New model finds previous cell division calculations ignore drivers at the molecular scale
When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass......»»
How do trees survive dry and hot summers? Leaf lifespan and growth recovery are key
Climate change has an effect on forests and trees. They suffer from heat waves and periods of drought. But although we see tree mortality increase as a result, much is still unknown about the underlying mechanisms......»»
Surprising role of female sex pheromone in crop pest points to new biocontrol possibilities
INRAE researchers have discovered that female pheromones play a remarkable role in the African cotton moth. In general, these pheromones trigger mate attraction, promoting encounters between males and females during reproductive periods. Astonishingl.....»»
Study suggests starvation decimated gray whales off the Pacific Coast: Can the giants ever recover?
When large numbers of gray whales began washing up along North America's Pacific Coast nearly six years ago, marine scientists could only speculate on the reason: Was it disease? Ocean pollution? Increasing ship collisions?.....»»
Attaching seaweed spores to used scallop shells could restore UK"s coastal kelp forests
Kelp spores are being seeded and grown on small rocks and scallop shells—a seafood waste product—in efforts to regenerate the UK's coastal kelp forests......»»
Droughts in Europe could be avoided with faster emissions cuts
Rapid climate action could mean devastating dry periods in the Mediterranean become less frequent by the end of the century, a new study shows......»»
Researchers identify key regulators underlying regeneration in Drosophila
Some animals possess the remarkable ability to regenerate lost structures, exemplified by a lizard regrowing its tail. However, this regenerative process must be tightly regulated by the body to ensure proper tissue organization and to prevent abnorm.....»»
The first Europeans reached Ukraine 1.4 million years ago, new study finds
During warm periods in Earth's history, known as interglacials, glaciers the size of continents pulled back to reveal new landscapes. These were new worlds for early humans to explore and exploit, and 1.4 million years ago this was Europe: a Terra nu.....»»
