Published Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease
(via sciencedaily.com)
Original source 
Acute graft-versus-host disease occurs when donor immune cells attack the recipient's tissues after an allogeneic hematopoietic stem cell transplantation (allo-HCT). Researchers recently identified a bacteriophage-derived enzyme called endolysin capable of targeting biofilms formed by Enterococcus faecalis. Their findings offer hope for tailored interventions in allo-HCT.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com)
Original source 
New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Discovery could help reduce adverse side effects of popular next-generation obesity medications
(via sciencedaily.com)
Original source 
By teasing apart the therapeutic benefits from the adverse effects of new generation obesity medications, researchers found a population of neurons in the brain that controls food intake without causing nausea in an animal model.
Published Big gain in battle against harmful bacteria
(via sciencedaily.com)
Original source 
An unexpected find has enabled important progress to be made in the battle against harmful bacteria.
Published The plague may have caused the downfall of the Stone Age farmers
(via sciencedaily.com)
Original source 
Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.
Published Researchers show promising material for solar energy gets its curious boost from entropy
(via sciencedaily.com)
Original source 
Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
Published Cutting farm nitrous oxide emissions helps climate and ozone layer
(via sciencedaily.com)
Original source 
Adding crushed basalt rocks and special fertilizers can reduce potent nitrous oxide (N2O) greenhouse gas emissions and help safeguard the stratospheric ozone layer.
Published Researchers examine economic effects on technological advancements of blue hydrogen production
(via sciencedaily.com)
Original source 
Experience from the deployment of blue hydrogen projects will be helpful in lowering future costs of hydrogen production and will remain cost competitive. Additionally, paired with extended tax incentives for carbon sequestration, costs could be significantly reduced further.
Published New one-step method to make multiple edits to a cell's genome
(via sciencedaily.com)
Original source 
A team of scientists have developed a new method that enables them to make precise edits in multiple locations within a cell -- all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com)
Original source 
The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Pinpointing coal plants to convert to nuclear energy, considering both practicality and community support
(via sciencedaily.com)
Original source 
An assessment ranks the feasibility of converting 245 operational coal power plants in the U.S. into advanced nuclear reactors, providing valuable insights for policymakers and utilities to meet decarbonization goals, according to a new study.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com)
Original source 
A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published Mining rare earth metals from electronic waste
(via sciencedaily.com)
Original source 
A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice.
Published Engine wear risk as planes swallow more dust waiting to land
(via sciencedaily.com)
Original source 
Planes flying into one of the world's busiest airports are ingesting around 10kg of dust per 1,000 flights.
Published Researcher finds lithium ion batteries a growing source of pollution
(via sciencedaily.com)
Original source 
The use of certain substances in batteries is polluting air and water.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds
(via sciencedaily.com)
Original source 
A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com)
Original source 
Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published Coral reefs: Battlegrounds for survival in a changing climate
(via sciencedaily.com)
Original source 
Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.
Published New extremely fast carbon storage technology
(via sciencedaily.com)
Original source 
A new way to store carbon captured from the atmosphere works much faster than current methods without the harmful chemical accelerants they require.
Published New bio-based tool quickly detects concerning coronavirus variants
(via sciencedaily.com)
Original source 
Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.
