T cells burn out just a few hours after encountering cancer tumors
Why do T cells become exhausted within a few hours of bumping into cancer? Enlarge / This microscopy image shows a cytotoxic T cell (blue) attacking a cancer cell (green) by releasing toxic chemicals (red). (credit: Alex Ritter,.....»»
Can Washington state hack and burn its way out of a future of megafires?
The teeth of the mower chewed through a stand of small trees and shrubs 30 miles from Mount Rainier and belched out a brown cloud of dirt and wood chips......»»
Nio secures $1.9 billion injection from parent, shareholders
A cash burn has triggered analysts’ concerns, and Nio, which has never been profitable, reported a 4.5 billion yuan second-quarter loss, though sales surged to 17.5 billion yuan......»»

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......»»
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.....»»
Opinion: Torrential rain represents an opportunity to build a better society
A month's worth of rain has poured down in just a few hours in parts of central and southern England. More than 300 flood-related emergency calls were made, major roads were submerged, trains were delayed, and an enormous sinkhole opened up on a foot.....»»
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.....»»
Overheard: View your repair shop from the perspective of the customer
Shop owners should spend a couple hours each month thinking about how the customer perceives their repair facility, Lauralee Schmidt, co-owner of Schmidt Auto Care in Springboro, Ohio, said on the "Ratchet+Wrench Radio" podcast......»»
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.....»»
Volunteers help seedlings take root as New Mexico attempts to recover from historic wildfire
A small team of volunteers spent a few hours scrambling across fire-ravaged mountainsides, planting hundreds of seedlings as part of a monumental recovery effort that has been ongoing following the largest wildfire in New Mexico's recorded history......»»
Study raises questions about validity of standard model of solar flares
Solar flares are extremely intense events that occur in the sun's atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electro.....»»
Researchers discover tumors inherited by generations of jellyfish-like creatures
Researchers from the CANECEV laboratory, an international collaboration between Deakin University and the University of Montpellier, have observed for the first time the birth of transmissible tumors in freshwater brown hydras—tiny, jellyfish-like.....»»
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......»»
Giant panda skin cells transformed into stem cells to help ensure their survival
A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells......»»
