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.....»»
New study shows environmental and social factors contribute to higher rates of pneumonia in children
A new study demonstrates that children who are exposed to a certain type of environmental air pollution are more likely to contract community acquired pneumonia, or CAP, and to be hospitalized for longer periods of time. Social factors, including rac.....»»
New study finds black spruce trees struggling to regenerate amid more frequent arctic fires
A new study, published in the Proceedings of the National Academy of Sciences (PNAS), finds that black spruce trees—a key species on the boreal landscape for millennia—are losing their resilience and capacity to regenerate in the face of warming.....»»
Aided by stem cells, a lizard regenerates a perfect tail for the first time in 250 million years
Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. No.....»»
Storing data as mixtures of fluorescent dyes
As the world's data storage needs grow, new strategies for preserving information over long periods with reduced energy consumption are needed. Now, researchers reporting in ACS Central Science have developed a data storage approach based on mixtures.....»»

Canonical has announced that it is extending the life of Ubuntu 14.04 and 16.04 to a decade. BetaNews: In other words, Ubuntu 14.04 and 16.04 are getting longer Extended Security Maintenance (ESM) periods as Canonical pushes back their End of Life (E.....»»
Baking greener bread after COVID
In the wake of the COVID-19 pandemic, we must not squander the clean energy gains that were made through reduced human activity and economic downturn during the periods of lockdown and beyond. That is the message from recent research published in the.....»»
Microbial study reveals extended lifespan of starved bacteria
A study of microbial populations under a prolonged period of starvation by Indiana University professor Jay T. Lennon and his laboratory could help researchers answer questions pertaining to chronic infections, the functioning of bacteria in the envi.....»»
Wear OS is getting a multi-generational leap in power thanks to Samsung
After years of starvation at the hands of Qualcomm, Samsung is here to save Wear OS. Enlarge / Samsung's 5 nm Exynos W920. Tomorrow is Samsung's big event for the back half of 2021, and in addition to launching some foldable smartphones, th.....»»
Releasing the heat: A new model to streamline the design of thermally efficient electrical contacts
When we think of modern technology in our daily lives, phones, tablets, and laptops, immediately come to mind. Using these electronic devices for extended periods of time leads to a familiar problem–overheating. As electronics have gotten smaller,.....»»
Genetic analysis of ancient brown bear skull suggests multiple waves of bears migrated to Honshu
An international team of researchers has found evidence of multiple waves of ancient brown bears migrating to the Japanese island of Honshu over vast periods of time. In their paper published in the journal Royal Society Open Science, the group descr.....»»
Long-period oscillations of the Sun discovered
A team of solar physicists led by Laurent Gizon of the Max Planck Institute for Solar System Research (MPS) and the University of Göttingen in Germany has reported the discovery of global oscillations of the Sun with very long periods, comparable to.....»»
Wallonia as an international reference for the timeline
Researchers at the Evolution & Diversity Dynamics Lab at the University of Liège (Belgium) have proposed a new definition of the geological boundary between the Devonian and Carboniferous periods (359 million years). This new definition has been tes.....»»
Nanofiber Membrane Filters 99.9% of Salt From Seawater Within Minutes
A team of Korean scientists may have found a way to desalinate seawater in minutes. An anonymous reader quotes a report from Interesting Engineering: When using membranes to filter seawater, the membrane must remain dry for long periods of time. If t.....»»
How seeds know it"s a good time to germinate
Dehydrated plant seeds can lay dormant for long periods—over 1,000 years in some species—before the availability of water can trigger germination. This protects the embryonic plant inside from a variety of environmental stresses until conditions.....»»
Scientists rejuvenate mouse brains with ketamine or flickering light
In defining periods of development, the brain re-organizes connections between its neurons more freely than in its adult form. Researchers have now discovered two methods to reopen such plasticity: repeated ketamine anesthesia and non-invasive 60 her.....»»

Scientists Develop Wireless Pacemaker That Dissolves In Body
A wireless pacemaker that can dissolve in the body has been created for patients who need only temporary help to regulate their heartbeat. The Guardian reports: While pacemakers can already be used for temporary periods, experts say there are problem.....»»
Texas authorities threaten SpaceX with legal action over beach closures, private security
SpaceX received a warning from a district attorney in Texas this week, warning that the company could be violating several state laws by shutting down public beaches for extended periods of time and using unlicensed security guards to ward people off.....»»
How cities can avoid "green gentrification" and make urban forests accessible
Many people have developed stronger relationships with urban nature during the pandemic. Some have enjoyed views of nearby trees and gardens during periods of isolation, taken walks after Zoom-filled days or socialized at a distance with friends in l.....»»
Arctic open-water periods are projected to lengthen dramatically by 2100
A team from the Centre for Earth Observation Science at the University of Manitoba has published a paper in the Nature journal Communications Earth & Environment that addresses a large gap in our understanding of Arctic Sea Ice coverage......»»
