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.....»»
At the crossroads of cell survival and death
National University of Singapore researchers discovered that a protein, known as MOAP-1, plays a crucial role in facilitating autophagy, a cellular "self-eating" process that recycles non-essential components during starvation......»»
How polar bears maintained highly specialized diets during periods of Arctic warming—until now
Polar bears are often considered the poster-child species for climate change impacts. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred prey—seals. Increased global temperatures are having the great.....»»
Global warming causes uneven changes in heat stress indicators
As the planet warms under the effects of human-caused climate change, prolonged periods of high temperatures are projected to become a significant public health challenge. The elderly are often more susceptible than others to the effects of temperatu.....»»

Even with regular exercise, astronaut"s heart left smaller after a year in space
With NASA preparing to send humans to Mars in the 2030s, researchers are studying the physical effects of spending long periods in space. Now a new study by scientists at UT Southwestern shows that the heart of an astronaut who spent nearly a year ab.....»»
Veera Health wants to help women in India navigate polycystic ovary syndrome
Polycystic ovary syndrome, or PCOS, is a common disorder that can cause irregular periods, infertility or gestational diabetes in women. And the condition is far from rare: PCOS impacts one in 10 women, meaning there’s a big market of people out th.....»»
Pancreatic cancer tumors use multiple mechanisms to avoid starvation: new target for treatment?
Researchers describe how pancreatic cancer cells use an alternative method to find necessary nutrients, defying current therapies, to help them grow and spread......»»
Blockstudio creates Parisian ambience in Moscow apartment
Russian practice Blockstudio has mixed different materials, textures and time periods within this new-build Moscow apartment to create the feeling of a lived-in Parisian interior. Read more Russian practice Blockstudio has mixed different ma.....»»
How critical part of lung forms at cellular level
Researchers have determined what happens at a cellular level as the lung alveolus forms and allows newborns to breathe air. Understanding this process gives researchers a better sense of how to develop therapies and potentially regenerate this critic.....»»
Astronauts in crewed missions to Mars could misread vital emotional cues
Living for nearly 2 months in simulated weightlessness has a modest but widespread negative effect on cognitive performance that may not be counteracted by short periods of artificial gravity, finds a new study published in Frontiers in Physiology. W.....»»
Mitochondria found to be protected by ketogenesis
Ketone bodies are generally an alternative energy source during starvation, but in newborns, ketogenesis is active regardless of nutritional status. In a recent study from Kumamoto University (Japan), researchers analyzed the effects of ketogenesis i.....»»
Weakened protections led to more disappearances of endangered Mexican wolves
Mexican wolves in the American Southwest disappeared more quickly during periods of relaxed legal protections, almost certainly succumbing to poaching, according to new research published Wednesday......»»
This sea slug can lose its head and regenerate new body in three weeks
She severs sea slugs down by the seashore... or rather, Sayaka Mitoh does so in the lab. At least two species of sacoglossan sea slugs are capable of severing their own heads from their bodies and then growing an entirely new.....»»
These sea slugs sever their own heads and regenerate new bodies
Starfish can regenerate their arms, salamanders are able to grow new tails, and axolotls re-form their spinal cords - but scientists have found sea slugs that can grow a whole new body......»»
These sea slugs sever their own heads and regenerate brand-new bodies
You've heard of animals that can lose and then regenerate a tail or limb. But scientists reporting in the journal Current Biology on March 8 have now discovered two species of sacoglossan sea slug that can do even better, shedding and then regenerati.....»»
Alvisi Kirimoto designs affordable housing complex with perforated metal balconies
Rome-based studio Alvisi Kirimoto has created an affordable housing complex with a brick facade and perforated metal balconies to help regenerate a neighbourhood in Barletta, Puglia. Read more Rome-based studio Alvisi Kirimoto has created an.....»»
Animals fake death for long periods to escape predators
Many animals feign death to try to escape their predators, with some individuals in prey species remaining motionless, if in danger, for extended lengths of time......»»
Division of labor within regenerating liver maintains metabolism, mouse study finds
The liver has a rare superpower among body organs - the ability to regenerate. It also keeps up its metabolic and toxin-removing work while regenerating, thanks to a subset of cells that expand their workload while the rest focus on multiplication, a.....»»

"Missing ice problem" finally solved
During glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the thickness of the glaciers. Using innova.....»»
