Optogenetic control reveals collective cell behavior
New research led by the Institute for Bioengineering of Catalonia (IBEC) has studied the migratory movement of groups of cells using light control. The results show that there is no leader cell that directs the collective movement, as previously thou.....»»
Study reveals flies more vulnerable than bees to climate change
Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth's most prolific pollinators—and new research led by Penn State scientists suggests they are increasingly at risk due to rising global temperatures......»»
Newly identified mysterious fossil seed reveals Ice Age climate patterns
La Brea Tar Pits scientists have identified a previously unknown juniper species as Juniperus scopulorum, commonly known as the Rocky Mountain Juniper. The successful identification, along with the first-ever radiocarbon dating of these fossil plants.....»»
Scientists achieve collective quantum behavior in macroscopic oscillators
Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the q.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Examination of political investments reveals democrat involvement spooks corporate raiders
Stock investments by politicians have long drawn public scrutiny. Under a 2012 law, members of the U.S. Congress must disclose transactions over a $1,000 threshold. Early in the COVID-19 pandemic, lawmakers on both sides of the aisle were criticized.....»»
Cellular RNA plays key role in antiviral defense, study finds
Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune re.....»»
Early warning tool may help control huge locust swarms
Desert locusts typically lead solitary lives until something—like intense rainfall—triggers them to swarm in vast numbers, often with devastating consequences......»»
Evolutionary study reveals toxic reach of disease-causing bacteria across plant kingdom
The capacity of bacteria to spread disease across the plant kingdom may be much more widespread than previously suspected, according to new analysis......»»

Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
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.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
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......»»
