Bioenergy: Precision gene editing in miscanthus
Researchers have successfully demonstrated precision gene editing in miscanthus, a promising perennial crop for sustainable bioenergy production. Biologists edited the genomes of three miscanthus species using CRISPR/Cas9 — a far more targeted and eff…
Study reveals key aspect of the finely tuned regulation of gene expression
A team of researchers unveils a novel, key aspect of enhancer-mediated regulation of gene expression and proposes a mechanism that explains the tight connection between gene enhancers and promoters.
Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes
On the short-lived island of Hunga Tonga Hunga Ha’apai, researchers discovered a unique microbial community that metabolizes sulfur and atmospheric gases, similar to organisms found in deep sea vents or hot springs.
‘Smart’ walking stick could help visually impaired with groceries, finding a seat
For people who are blind or visually impaired, finding the right products in a crowded grocery store can be difficult without help. A team of computer scientists is trying to change that.
Nearly 50-meter laser experiment sets record in university hallway
Researchers set a record by guiding light in 45-meter-long air wave-guides.
New nanoparticles deliver therapy brain-wide, edit Alzheimer’s gene in mice
Researchers describe a new family of nano-scale capsules made of silica that can carry genome-editing tools into many organs around the body and then harmlessly dissolve.
Simulations and experiments reveal unprecedented detail about water’s motion in salt water
In salt water solutions, water molecules rapidly move around salt ions at a scale of more than a trillion times a second, according to both experiments and simulations.
High frequency brain wave patterns in the motor cortex can predict an upcoming movement
A new study has found high frequency propagating activity patterns in the motor cortex that contain details of upcoming movement — information that could lead to the development of better brain-machine interfaces.
Using cancer cells as logic gates to determine what makes them move
Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate — a simple computer — to better understand what causes specific cells to migrate.
Squirrels that gamble win big when it comes to evolutionary fitness
Imagine overhearing the Powerball lottery winning numbers, but you didn’t know when those numbers would be called — just that at some point in the next 10 years or so, they would be. Despite the financial cost of playing those numbers daily for that p…
Stars disappear before our eyes
A startling analysis from Globe at Night — a citizen science program — concludes that stars are disappearing from human sight at an astonishing rate. The study finds that, to human eyes, artificial lighting has dulled the night sky more rapidly than …
Genes that cause rare hidden cancer revealed
Several genes that cause sarcoma have been identified in the first comprehensive genetic map of sarcomas. The research has wide implications for people living with sarcoma and their families — allowing detection of the cancer earlier and potentially i…
DNA from domesticated chickens is tainting genomes of wild red junglefowl, study finds
The red junglefowl — the wild ancestor of the chicken — is losing its genetic diversity by interbreeding with domesticated birds, according to a new study.
Parasitic mites’ biting rate may drive transmission of Deformed wing virus in honey bees
Varroa destructor is an ectoparasitic mite that can cause European honey bee colonies to collapse by spreading Deformed wing virus as they feed. A study suggests a relatively small number of mites can contribute to a large number of infected bees.
Tracing the flow of water with DNA
Environmental DNA analysis of microbial communities can help us understand how a particular region’s water cycle works. Basel hydrogeologist Oliver Schilling recently used this method to examine the water cycle on Mount Fuji. His results have implicati…
Massive fuel-hungry black holes feed off intergalactic gas
Research has revealed how supermassive black holes (SMBHs) are feeding off gas clouds which reach them by traveling hundreds of thousands of light years from one galaxy to another.
Omicron caused fewer cases of MIS-C in children than delta and they were milder, says new study based on 2021-22 data
A new study reveals that there were fewer cases of multi-system inflammatory syndrome in children (MIS-C) during the omicron wave of the pandemic than the delta wave.
How pancreatic cancer defies treatment
Researchers describe how pancreatic cancer stem cells leverage a protein in a family of proteins that normally suppress tumors to instead do the opposite, boosting their resistance to conventional treatments and spurring growth.
