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.....»»
Lethal climate change millions of years ago was due to volcanic eruptions, scientists conclude
Climate change that has occurred over the past 260 million years and brought about mass extinctions of life during these periods was due to massive volcanic eruptions and subsequent environmental crises, concludes a team of scientists......»»
Extracellular vesicles study outlines new strategies to combat neurodegenerative diseases
A new study by the University of Barcelona could drive the design of future strategies to regenerate damaged brain areas in neurodegenerative diseases. The study emphasizes the role of neuron-derived extracellular vesicles in the processes that modul.....»»
Monocyte-derived macrophages could be central to liver regeneration
The liver is a vital organ that plays a role in many essential functions, including digestion, detoxification, and metabolism. When the liver is damaged, it has the remarkable ability to regenerate itself. However, the process of liver regeneration i.....»»
Study shows bacteria in the soil can defy periods of drought
While many bacteria become inactive during dry spells, specific groups persist and even thrive. A new study, published in Nature Communications and conducted by the Center for Microbiology and Environmental Systems Science (CeMESS) at the University.....»»
Scientists regenerate neurons that restore walking in mice after paralysis from spinal cord injury
In a new study in mice, a team of researchers from UCLA, the Swiss Federal Institute of Technology, and Harvard University have uncovered a crucial component for restoring functional activity after spinal cord injury. The neuroscientists have shown t.....»»
How Europe"s forests regenerate—without any human interference
Yannek Käber, a doctoral student in the Professorship of Forest Ecology at ETH Zurich, and his colleagues from ETH and WSL together with the European Forest Research Initiative (EuFoRIa), have taken a look at regeneration in protected European fores.....»»
New research finds Late Pleistocene glaciations terminated by Earth"s axis tilt rather than orbital eccentricity
Glacial cyclicity of the Earth has often been considered on 100,000 year timescales, particularly for the Late Pleistocene (~11,700 to 129,000 years ago) swapping between periods of extensive polar and mountain glacier ice sheets, to warmer interglac.....»»
Water harvesting in Death Valley: Conquering the arid wilderness
Korea is regarded as a "water-stressed nation." Although the country receives an annual precipitation of approximately 1,300mm, it is characterized by concentrated periods and specific regions, thereby giving rise to challenges stemming from water sc.....»»
India was a tree planting laboratory for 200 years. Here are the results
Allowing forests to regenerate on their own has been championed as a strategy for reducing planet-heating carbon in the atmosphere while also boosting biodiversity, the benefits ecosystems offer and even the fruitfulness of livelihoods......»»
Satellites document effects of heat waves on plants
A new scientific study shows how periods of drought affect photosynthesis throughout the course of the day. The study found that plants in regions that are typically dry increase their CO2 intake during the morning hours during a heat wave and decrea.....»»
Water-purifying cup makes drinkable water from creeks and streams
A rash of storms in Texas in recent years—from Hurricane Harvey in 2017 to the deep freeze in 2021—has put big chunks of the population in danger and left millions without electricity or water for long periods......»»
Machine learning meets behavioral neuroscience: Allowing for a more precise phenotyping
A new computer program allows scientists to observe the behavior of multiple animals simultaneously and over extended periods, while automatically analyzing their motion. What may seem obvious marks a significant milestone, and paves the way for robu.....»»
Study uncovers the secrets of plant regeneration
Plants have the unique ability to regenerate entirely from a somatic cell, i.e., an ordinary cell that does not typically participate in reproduction. This process involves the de novo (or new) formation of a shoot apical meristem (SAM) that gives ri.....»»
Water temperature found to not impact blue-green algae blooms
Even if most cyanobacteria blooms in Canada's lakes happen during the hottest periods of summer, water temperature seems to have little to no impact on the development of these potentially toxic bacteria better known as blue-green algae. Details of t.....»»
Alone in a dark cave: What can we learn from extreme survival experiments?
Why do humans undertake journeys of personal exploration, or subject themselves to challenging conditions for long periods of time? What might we learn from their experiences?.....»»
Gullies on Mars could have been formed by recent periods of liquid meltwater, study suggests
A study led by Brown University researchers offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on Mars......»»
Sihoo Doro C300 Ergonomic Office Chair review: extra lumbar support where you need it
If you suffer from aches and pains from sitting at your desk all day, the Sihoo Doro C300 may be the fix you're looking for — provided you're the right size.Working a desk job is surprisingly hard on your body. Long periods of inactivity can cause.....»»
Ancient herbivore"s diet weakened teeth and lead to eventual starvation, suggests study
A team of researchers from the University of Bristol have shed light on the life of the ancient reptile Rhynchosaur, which walked the earth between 250-225 million years ago, before being replaced by the dinosaurs......»»
Plant cells use mechanical cues to regenerate damaged tissues, shows study
Plants have an impressive ability to regenerate damaged tissues, but how they do it is not fully understood. Now, researchers from Japan have discovered the mechanisms involved in this superpower......»»
Improved model offers out-of-this-world control on ice age cycles
A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show that the glacial cycle was driven primarily by ast.....»»
