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.....»»

Florida Manatees Facing Starvation to Be Fed in Trial Program
Wildlife officials in Florida are preparing to feed manatees in the wild, an unprecedented response to the animals' mass starvation caused by the loss of seagrasses they normally eat. From a report: So far this year, 1,056 manatees have died in Flori.....»»
Environmental groups take steps to sue over manatee deaths
Environmental groups took the first step Monday toward suing the Environmental Protection Agency over water pollution that caused a catastrophic number of manatee deaths this year from starvation......»»
Snow drought research finds predictability in uncertainty
Periods of record low snow levels over the past decade have increased the urgency of snow research. As snow studies expand, usage of the term "snow drought" to describe seasons of abnormally low snowpack has become common. But disagreements still exi.....»»
The impact of school closures: Why reception year is so crucial to a child"s development
The pandemic has held back the learning of the youngest schoolchildren. A recent report has found that children in year one in the 2020-2021 academic year—those who had missed significant periods of their reception year education during COVID-19 sc.....»»
Global research shows that digital contact does not enhance wellbeing
New research involving Nottingham Trent University (NTU) has found that during periods of limited face-to-face contact, such as that experienced by most people during COVID-19 lockdowns, digital contact is particularly harmful for young people's well.....»»
How Hydra animals regenerate their own heads
A new paper in Genome Biology and Evolution maps out for the first time how Hydra, which are a group of small aquatic animals, can regenerate their own heads by changing the way that their genes are regulated, known as epigenetics......»»
Coaxing jellyfish, flies and mice to regenerate body parts
Caltech researchers have discovered certain conditions that enable different laboratory animals to regenerate amputated appendages. Upon consuming a diet high in sugar and an essential amino acid, three different species—the moon jellyfish Aurelia.....»»
Zebra finches alter song to eggs during hot periods to repress heat production in embryo cells
A team of researchers from Deakin University in Australia and Clemson University in the U.S. has found that female finches change the song they sing to their eggs when temperatures rise. This results in hatchling mitochondria producing more ATP and l.....»»
Manatee club applauds state, feds for agreeing to emergency feeding as mammals die off
The Save the Manatee Club applauded state and federal wildlife authorities Monday night for their staff-level agreement for a trial, emergency feeding of Central Florida manatees at risk of starvation as winter months approach......»»
Cells or Drugs? The Race to Regenerate the Heart
Researchers are debating how to convince the heart to heal itself instead of laying down scar tissue after a heart attack -- Read more on ScientificAmerican.com.....»»
Volcanic fertilization of the oceans drove severe mass extinction, say scientists
Scientists at the University of Southampton have discovered that two intense periods of volcanism triggered a period of global cooling and falling oxygen levels in the oceans, which caused one of the most severe mass extinctions in Earth history......»»
Heart repair and regeneration after a heart attack
Twenty years ago, clinicians first attempted to regenerate a failing human heart by injecting muscle myoblasts into the heart during a bypass operation. Despite high initial hopes and multiple experimental and clinical studies since then, outcomes ha.....»»
Heat, no food, deadly weather: Climate change kills seabirds
The warming of the planet is taking a deadly toll on seabirds that are suffering population declines from starvation, inability to reproduce, heat waves and extreme weather......»»
Stem cell memories may drive wound repair, and also chronic disease
A trifling paper cut is a site of frenzied activity. Within it, a squad of epidermal stem cells briskly regenerate to patch up the wound. A closer inspection of this war-torn swath of epidermis will reveal that while some of the stem cells are native.....»»
Master developmental genes play role in adulthood
Among their many extraordinary feats, some planarian flatworms reproduce by tearing off pieces of themselves to regenerate new worms. Now, researchers have discovered that this process is controlled by Hox genes, a family of genes known to orchestrat.....»»
Dogs and TV: Here"s what we know about how they respond
On the face of it, a recently launched TV channel dedicated to dogs seems, well, barking mad. But our pets often spend long periods of time home alone, and providing some form of enrichment and stimulation can be very beneficial to dogs and their own.....»»
Study: Glow-in-the-dark worms may shed light on the secrets of regeneration
Fluorescent proteins enable scientists to watch cells inside as the worms regenerate. Enlarge / A whole three-banded panther worm from the muscle transgenic line, where the muscle cells are glowing green. (credit: Lorenzo Ricci).....»»
Study explores the global distribution, trends and drivers of flash droughts
Flash droughts are described as rapidly developing, unexpected periods of drought. These flash droughts can cause severe impacts to agricultural and ecological systems and cause ripple effects that extend even further......»»
Droughts create fertile ground for cholera; plans are needed to face more dry periods
Africa has a disproportionately high burden of cholera. The World Health Organization reports that between 40 million and 80 million people in Africa live in cholera hotspots. Globally, disease outbreaks have more than tripled since 1980, with 1,307.....»»
