Researchers find how cells move while avoiding adhesion
Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms of this relationship have remained elusive for decades. Now, researchers from the Max Delbrück Center for Molecular Medic.....»»
New observatory in Chile—the highest in the world—aims to reveal origins of planets, galaxies and more
How do planets form? How do galaxies evolve? And ultimately, how did the universe itself begin? A unique astronomical observatory that researchers hope will unravel some of the biggest mysteries out there marks its opening on April 30, 2024......»»

Researchers forced to cut short an annual survey of wildlife on a remote Lake Superior island this winter due to unusually warm weather announced Tuesday that they managed to gather data that shows the wolf population is stable......»»
G7 to phase out coal-fired power plants by mid-2030s
G7 ministers agreed a timeframe Tuesday for phasing out coal-fired power plants, setting as a goal the mid-2030s, in a move hailed as significant by some environmentalists but slammed as "too late" by others......»»
Organic electrochemical transistors: Scientists solve chemical mystery at the interface of biology and technology
Researchers who want to bridge the divide between biology and technology spend a lot of time thinking about translating between the two different "languages" of those realms......»»
It may be time to eliminate the best-before date on food packaging, say smart packaging researchers
The inventors of a suite of tests that enable food packages to signal whether their contents are contaminated are working to bring producers and regulators together to get their inventions into commercial products, with the goal of preventing illness.....»»
Big data reveals true climate impact of worldwide air travel
For the first time ever, researchers have harnessed the power of big data to calculate the per-country greenhouse gas emissions from aviation for 197 countries covered by an international treaty on climate change......»»
Should online educational platforms offer courses following a schedule or release them on demand?
Researchers from Carnegie Mellon University and University of Pennsylvania have published a new Journal of Marketing study that examines online educational platforms and the question of whether they should release content through a scheduled format t.....»»
Study uncovers the secret of long-lived stem cells
Nothing lives forever, but compared to other cells in the body, hematopoietic stem cells (HSCs) are remarkably long-lived. HSCs are blood-forming cells—they give rise to rapidly dividing progenitor cells, which in turn generate hundreds of billions.....»»
Low-intensity grazing is locally better for biodiversity but challenging for land users, study shows
A team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), and the Helmholtz Centre for Environmental Research (UFZ) has investigated the motivation and potential incentives for and challenge.....»»
The academic sleuth facing death threats and ingratitude
Lonni Besançon devotes evenings and weekends to rarely appreciated sanitation work. By examining scientific articles after they are published and exposing shortcomings, he has made himself an enemy of both researchers and publishers. It has gone so.....»»
Researchers explore an old galactic open cluster
Using data from ESA's Gaia satellite, astronomers from Turkey and India have investigated NGC 188—an old open cluster in the Milky Way. Results of the study, published April 19 on the pre-print server arXiv, deliver important insights into the para.....»»
Researchers suggest that mechanical pressure triggers a key event in HIV infection
It has been more than 40 years since the beginning of the HIV/AIDS epidemic and scientists still don't fully understand how HIV enters and replicates in human cells, which has hindered the development of treatments......»»
Discovery of mechanism plants use to change seed oil could impact industrial, food oils
Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make......»»
New research reveals terahertz waves" impact on dynamics of nanoconfined water molecules
In a new discovery, researchers have revealed novel insights into the behavior of water molecules confined within nanostructures. Their study, published in Science Advances on April 24, delves into how terahertz (THz) waves influence the dynamics of.....»»
First high-resolution 3D nanoscale chemical imaging achieved with multi-modal tomography
By exploiting a smart learning algorithm that fuses two microscopy signals, University of Michigan researchers have accomplished high-resolution, efficient 3D chemical imaging for the first time at the one-nanometer scale. For context, a nanometer is.....»»
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modeling climate changes from times long past. And they show that plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth......»»
