How plants heal wounds: Mechanical forces guide direction of cell division
Plants are made up of very rigid cells. Much like bricks in a wall, this feature gives them the structural support to maintain their shape and to stand upright against gravity. However, just like any living organism, plants can be injured, for instan.....»»
New AA-powered AirTag case promises 10-year lifespan
Aluminum AirTag case replaces coin cell with 2 AA Lithium batteries for extended lifespan. On Wednesday, a startup announced TimeCapsule, a new $20 battery case purported to exten.....»»
Ferns" ancient resilience aids modern ecosystem recovery after disasters
Scientists have suggested an updated framework for the role of ferns in environmental recovery from disaster. Instead of competing with other organisms, ferns may act as facilitators that ease the way for other plants and animals to re-establish them.....»»
Global study reveals phenological divergence between plants and animals under climate change
A collaborative study reveals the distinct mechanisms by which plants and animals respond to climate change in their life-cycle phenology. This research, led by Piao Shilong's team and Zhang Yao's team from the Institute of Carbon Neutrality at Pekin.....»»
Active particles reorganize 3D gels into denser porous structures, study shows
Colloidal gels are complex systems made up of microscopic particles dispersed in a liquid, ultimately producing a semi-solid network. These materials have unique and advantageous properties that can be tuned using external forces, which have been the.....»»
Discovery of egg"s immune-like attack on sperm mitochondria may aid fertility
Within minutes of fertilization, the egg of a fruit fly becomes a scene from the battle of the sexes. The egg attacks and destroys the cellular "power plants" (mitochondria) from the sperm that had fertilized it, so that only its own mitochondria rem.....»»
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.....»»
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.....»»
Solving renewable energy’s sticky storage problem
When the Sun doesn't shine and the wind is calm, humankind still needs power. When the Sun is blazing and the wind is blowing, Germany’s solar and wind power plants swing into h.....»»
Tech used by WWI flying aces inspires new cellular behavior discovery
Researchers at the University of Massachusetts Amherst have designed a new technology that takes inspiration from WWI fighter aircraft machine gun and propeller synchronization to manipulate cell behavior by precisely modulating the pH of the cell's.....»»
Cenotectic concept redefines search for life on icy worlds
As NASA's Europa Clipper embarks on its historic journey to Jupiter's icy moon, Europa, Dr. Matt Powell-Palm, a faculty member at Texas A&M University's Department of Mechanical Engineering, has unveiled research that could transform our understandin.....»»
South Florida"s beachfront buildings found to be sinking faster than expected
A team of mechanical, architectural and environmental engineers, geoscientists, and geoinformation specialists affiliated with several institutions in the U.S. and Germany has found that many of the tall, heavy buildings along the coast of South Flor.....»»
Astronomers detect new 1.9-second pulsar using FAST
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers have discovered a new pulsar with a spin period of about two seconds. The newly detected pulsar, designated PSR J1922+37, was found in the direction of open.....»»
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.....»»
Top 10 plant and fungal species named new to science in 2024
Scientists from the Royal Botanic Gardens, Kew and their partners reveal their pick of the top 10 plants and fungi named new to science in 2024......»»
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.....»»
NASA finds "sideways" black hole using legacy data and new techniques
NASA researchers have discovered a perplexing case of a black hole that appears to be "tipped over," rotating in an unexpected direction relative to the galaxy surrounding it. That galaxy, called NGC 5084, has been known for years, but the sideways s.....»»
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.....»»
