Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Transforming caragana waste into nutritious ruminant feed
In an advance for agricultural waste management, scientists from the Chinese Academy of Sciences have devised a method to convert Caragana korshinskii Kom. waste, a common forestry byproduct in China, into a potential ruminant feed. The research, pub.....»»
Building better bone grafts: Nanofibrous scaffolds to activate two main collagen receptors in bone cells
Each year, about 2.2 million bone-grafting procedures are performed worldwide, the gold standard of care being autografting, which uses the patient's own bone for tooth implantation and to repair and reconstruct parts of the mouth, face and skull......»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Rethinking privacy: A tech expert’s perspective
Data privacy has become one of the most pressing challenges of our time, but it didn’t happen overnight. The proliferation of data collection, coupled with the rise of advanced technologies like artificial intelligence and machine learning, has.....»»

Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
Meta reveals Orion, its first fully holographic AR glasses and ‘neural interface’
At the end of the Meta Connect keynote, Meta shared an exclusive look at its first fully functioning prototype of "Orion" -- fully holographic AR glasses......»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
New insights into hot carrier solar cells: Study explores hot electron tunneling and collection to enhance efficiency
Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley–Queisser efficiency limit, which is a theoretical maximum efficien.....»»
Mechanism behind autophagy trigger unveiled
An international research team led by Osaka University has identified a new mechanism crucial for the initiation of autophagy, a self-degradation process cells use to eliminate unneeded or damaged components. In recent years, autophagy has also been.....»»
Yeast chit-chat: How microorganisms communicate food shortages
To grow and survive, tiny organisms such as yeast must sometimes adapt their nutrient sources in response to changes in the environment. FMI researchers have now found that yeast cells communicate with each other to use less favorable nutrients if th.....»»
Spinning artificial spider silk into next-generation medical materials
It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one c.....»»
10 long years with—and good riddance to—Apple’s iPhone 6 design
Op-ed: On living with the iPhone 6 design—and its flaws—for a full decade. Enlarge / The iPhone 6 and 6 Plus, the first iteration of a very, very long-lived phone design. (credit: Andrew Cunningham) This past weekend.....»»
Global crises are multiplying: Here"s how science can help our public decision-makers
Housing, climate, cost of living, health—the multitude of interconnected crises the world is facing has spawned a new term: "polycrisis.".....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Transforming agriculture from carbon source to sink: Study shows potential of carbon sequestration options
The food system is one of the most significant sources of greenhouse gas emissions on the planet, making the reduction of emissions in this sector a priority for policymakers around the world. IIASA researchers explored the potential of carbon seques.....»»
