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.....»»
"Carbon vault" peat suffers greatly from drought, finds study
Peatlands are affected more by drought than expected. This is concerning, as these ecosystems are an important ally in the fight against climate change. Following long periods of drought, peat is able to absorb little to no extra carbon (CO2). Increa.....»»
Jellyfish regenerate lost tentacles, and now we know how
Jellyfish regeneration looks a lot like that of amphibians and other animals. Enlarge (credit: Gerard Soury) The mythical Hydra may have been able to grow one of its many heads back every time it suffered a decapitation,.....»»
Research shows advisability of replanting conifer forests sooner rather than later after wildfires
Warmer and drier climate conditions in western U.S. forests are making it less likely that trees can regenerate after wildfires. Scientists at The University of New Mexico are experimenting and learning about reforestation and the challenges presente.....»»
Korean artificial sun, KSTAR, completes divertor upgrades for long pulse operations
The Korean artificial sun, KSTAR, has completed divertor upgrades, allowing it to operate for extended periods sustaining high-temperature plasma over 100 million degrees......»»
How jellyfish regenerate functional tentacles in days
At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days—but how? Regenerating functional tissue across species, including salamanders and insects, relies on the ability to form a.....»»
Scientists describe 153 new species in 2023
Researchers at the California Academy of Sciences described 153 new animal, plant, and fungi species in 2023, enriching our understanding of Earth's biodiversity and strengthening our ability to regenerate the natural world. The new species include 6.....»»
Adapting to hypoxia: Zooplankton influence efficiency of biological carbon pump in the Humboldt Current
Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this.....»»
X-ray method enables micron-resolution imaging of living organisms over long time periods
Researchers have developed an X-ray imaging technique that can produce detailed images of living organisms with a much lower X-ray dose than previously possible. The advance enables small organisms or other sensitive samples to be studied at high res.....»»
Flexible parental leave among immigrant mothers can promote integration
Mothers who took parental leave part-time or for shorter periods were more likely to engage in income-generating activities or pursue education. A new study uncovers surprising patterns in parental leave usage among newly arrived migrant women in Swe.....»»
Childhood in medieval Bavaria: What teeth reveal about nutrition and migration
New research findings reveal that some children in early medieval Bavaria were breastfed for much longer periods than today. Also, many early Bavarians buried around 500 AD originate from other geographical regions where feeding practices apparently.....»»
HomeKit Weekly: The benefits of HomeKit when traveling for an extended period
Back in September, my wife and I spent a few weeks traveling through Scotland and London. It was an amazing time, and I highly recommend both places. Since our home was empty for long periods outside of family visiting to check on the house (I am alw.....»»
Venmo Groups feature lets you split bills, or track longer-term shared expenses
A new Venmo Groups feature makes it easy for family and friends to split bills, track shared holiday spending, or even sort out shared expenses for longer periods. The PayPal-owned app says that there’s no longer a need to use third-party apps o.....»»
Five new pulsars discovered with FAST
Using the Five-hundred Aperture Spherical Telescope (FAST), astronomers from China and Australia have discovered five new pulsars, two of which turned out to have ultra-short spin periods. The finding was reported in a research paper published Novemb.....»»
New study sheds light on Adélie penguins" reliance on declining sea ice during molt
A study published in the Proceedings of the National Academy of Sciences underscores the pivotal role that seasonal Antarctic sea ice plays in the annual molting periods of Adélie penguins......»»
Stem cell research paves way toward regenerating skeletal muscle
Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA are one step closer to developing stem cell therapies to regenerate skeletal muscle in humans. Working in mice, the UCLA team discovered how to mak.....»»
Why some worms regenerate and others do not
Why are so few species able to regenerate damaged or missing body parts, even though regeneration might seem an obvious survival advantage? Researchers at the Max Planck Institute (MPI) for Multidisciplinary Sciences in Göttingen, Germany, and colle.....»»
Geotechnical centrifuge modeling for simulating long-term radionuclide migration in large-scale fractured rocks
Deep geological disposal is a globally recognized and safe method for long-term management of high-level radioactive waste (HLW). However, over extended periods of nuclear waste storage, there is the potential for the waste canister to experience lea.....»»
California supervolcano is cooling off but may still cause quakes
Since the 1980s, researchers have observed significant periods of unrest in a region of California's Eastern Sierra Nevada mountains characterized by swarms of earthquakes as well as the ground inflating and rising by almost half an inch per year dur.....»»
Subalpine forests in the Northern Rockies are fire resilient—for now
Research shows that over 4,800 years in the Northern Rockies during wet periods and dry periods, subalpine forests consistently recovered from wildfires, growing back vegetation and leaving evidence of their resilience in lake sediment cores......»»
Aurora records reveal shortened solar cycle during Maunder minimum
Sunspots change in number depending on how much magnetic activity the solar dynamo generates. But there's not total chaos: These changes occur in a cycle, which lasts about 11 years on average. The sun also experiences extended periods of low activit.....»»
