How marine worms regenerate lost body parts: Return of cells to stem cell-like state could be key
Many living organisms are able to regenerate damaged or lost tissue, but why some are particularly good at this and others are not is not fully understood. Molecular biologists Alexander Stockinger, Leonie Adelmann and Florian Raible from the Max Per.....»»
Study reveals how transcription factors navigate DNA architecture to shape cellular identity
A new study led by Prof. Yosef Buganim from the Hebrew University of Jerusalem and Dr. Abdenour Soufi from the University of Edinburgh reveals how transcription factors (TFs)—key proteins that regulate gene activity—navigate DNA and chromatin str.....»»
Sentinel-1 data reveals Arctic glacier retreat
As Arctic temperatures rise, marine-terminating glaciers—especially in places like Svalbard—are undergoing rapid retreat and intensified calving. The Space for Shore project utilizes radar data from the Copernicus Sentinel-1 mission to provide pr.....»»
Molecular gardening: New enzymes discovered for protein modification pruning
Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including cancer and neurodegenerative disorders......»»
White House unveils new climate goals weeks before Trump"s return
President Joe Biden's administration on Thursday unveiled a new climate target under the landmark Paris accord, just weeks before Donald Trump's return to the White House threatens to upend US efforts to combat global warming......»»
Study reveals how global connections boost city economies
As city population grows, so does violent crime, contagious diseases, and per-capita GDP. A significant body of research has investigated what drives this scaling relationship, examining factors within a city......»»
New software unlocks secrets of cell signaling, showing realistic simulations
Researchers at University of California San Diego have developed and tested a new software package, called Spatial Modeling Algorithms for Reactions and Transport (SMART), that can realistically simulate cell-signaling networks—the complex systems.....»»
Capybaras found dead from rabies on Brazilian island underline need to monitor virus
Three capybaras (Hydrochoerus hydrochaeris) died from rabies on Anchieta Island in the municipality of Ubatuba, São Paulo state, Brazil, between December 2019 and January 2020. One was found dead, and two exhibited hindlimb paralysis before dying. A.....»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Nature"s instructions: How fungi make a key medicinal molecule
For roughly a century, ever since Alexander Fleming's accidental discovery of penicillin in 1928, fungi have proven to be a goldmine for medicines. They've provided treatments for a wide range of diseases, from infections and high cholesterol to orga.....»»
How one state"s repeal of a prison "pay-to-stay" law could guide national reform
Nearly every state requires incarcerated individuals to pay for room, board and basic services under so-called "pay-to-stay" laws. In 2019, Illinois became one of the first to repeal such a law—a move that prompted Brittany Friedman, assistant prof.....»»
Boomerang workers: helpful returnees or resented colleagues?
While movement from job to job throughout one's career is expected, little research has evaluated the effects of hiring boomerang workers—those who return to a former employer. A new study by a University of California, Davis, researcher and collea.....»»
New method maps hundreds of proteins in cell nuclei simultaneously
Caltech researchers have developed a new method to map the positions of hundreds of DNA-associated proteins within cell nuclei all at the same time. The method, called ChIP–DIP (Chromatin ImmunoPrecipitation Done In Parallel), is a versatile tool f.....»»
PSA: AirPods Max are missing a key feature on the new USB-C model
Apple’s AirPods Max update this year wasn’t a full-blown AirPods Max 2, but rather a switch to USB-C and color swap. Unfortunately, the also lost a key feature that was supported by the original. more….....»»
Assault on DEI: Critics use simplistic terms to attack the programs, but they are key to uprooting workplace bias
Prominent politicians have recently increased their attacks on workplace programs that promote diversity, equity and inclusion, or DEI. They claim that initiatives that seek to be inclusive are divisive and lack merit......»»
Azo-menthol: New molecule can regulate ion channels using light
Located in the cell membrane, TRPM8 ion channels are known as receptors that recognize cold and respond to menthol, the cooling agent in peppermint. In addition, these channels influence pain perception and play a key role in numerous diseases. This.....»»
Baby humpback whale recordings reveal vocalizations directed to their mothers
A team of marine biologists, zoologists, and cetologists from Université Paris-Saclay, Université d'Antananarivo and Ambodiforaha Sainte Marie has learned more about the ways baby humpback whales and their mothers communicate......»»
Melting sea ice in Antarctica causes ocean storms, scientists say
The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday......»»
Survey of 26,000 dead stars confirms key details of extreme stellar behavior
A study of more than 26,000 white dwarf stars has confirmed a long-predicted but elusive effect in these ultra-dense, dying stars: Hotter white dwarfs are slightly puffier than cooler ones, even when they have the same mass......»»
Physicists magnetize a material with light: Terahertz technique could improve memory chip design
MIT physicists have created a new and long-lasting magnetic state in a material, using only light......»»
Building a backbone: Scientists recreate the body"s "GPS system" in the lab
Scientists at the Francis Crick Institute have generated human stem cell models which, for the first time, contain notochord—a tissue in the developing embryo that acts like a navigation system, directing cells where to build the spine and nervous.....»»
