Published Pacific cod can't rely on coastal safe havens for protection during marine heat waves



During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new study found.
Published Bird flu stays stable on milking equipment for at least one hour



H5N1 virus in unpasteurized milk is stable on metal and rubber components of commercial milking equipment for at least one hour, increasing its potential to infect people and other animals.
Published Wolves reintroduced to Isle Royale temporarily affect other carnivores, humans have influence as well



In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers found that the effects of wolves on Isle Royale have been only temporary. And even in the least-visited national park, humans had a more significant impact on carnivores' lives.
Published US Clean Water Act leaves about 55% of water flowing out of rivers vulnerable to pollution



The Supreme Court ruled last year that rivers that only flow in response to weather events -- called ephemeral streams -- do not fall under the protection of the Clean Water Act. New research suggests that this now leaves many U.S. waterways vulnerable to pollution.
Published A promising weapon against measles



What happens when measles virus meets a human cell? The viral machinery unfolds in just the right way to reveal key pieces that let it fuse itself into the host cell membrane.
Published Under pressure: How comb jellies have adapted to life at the bottom of the ocean



Researchers have studied the cell membranes of ctenophores ('comb jellies') and found they had unique lipid structures that allow them to live under intense pressure.
Published Potent therapy candidate for fatal prion diseases



Scientists have developed a gene-silencing tool that shows promise as a therapy against fatal prion diseases. The tool, a streamlined epigenetic editor, paves the way for a new class of genetic approaches to treat certain diseases.
Published New, holistic way to teach synthetic biology



Synthetic biology combines principles from science, engineering and social science, creating emerging technologies such as alternative meats and mRNA vaccines; Deconstructing synthetic biology across scales gives rise to new approach to uniting traditional disciplines; Case studies offer a modular, accessible approach to teaching at different institutions.
Published Climate change and sea level rise pose an acute challenge for cities with combined sewer systems



Older coastal cities, like Philadelphia, New York and Boston are at risk of being inundated by untreated sewage during floods. Due in part to the design of their combined sewer systems and in part due to sea level rise, these cities could be facing a growing public health crisis as climate change also drives more extreme precipitation. The group recently published research that modeled the potential extent of the problem in a section of the coastal city of Camden, New Jersey, and the effectiveness of one proposed intervention to help protect these communities.
Published Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds



We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.
Published Simple new process stores CO2 in concrete without compromising strength



By using carbonated -- rather than still -- water during the concrete manufacturing process, a team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction material.
Published Researchers address ocean paradox with 55 gallons of fluorescent dye



Researchers have directly measured cold, deep water upwelling via turbulent mixing along the slope of a submarine canyon in the Atlantic Ocean.
Published Brain's 'escape switch' controlled by threat sensitivity dial



Neuroscientists have discovered how the brain bidirectionally controls sensitivity to threats to initiate and complete escape behaviour in mice. These findings could help unlock new directions for discovering therapies for anxiety and post-traumatic stress disorder (PTSD).
Published Scientists discover genetic 'off switch' in legume plants that limits biological ability to source nutrients



A genetic 'off switch' that shuts down the process in which legume plants convert atmospheric nitrogen into nutrients has been identified for the first time by a team of international scientists.
Published Cell division: Before commitment, a very long engagement



Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a reversible intermediate state, according to a new discovery. Their revelation of this fundamental feature of biology includes details of its mechanisms and dynamics, which may inform the development of future therapies targeting cancers and other diseases.
Published New tool enables faster, more cost-effective genome editing of traits to improve agriculture sustainability



New research had the goal of reducing the time and cost it takes to bring an improved crop to the marketplace to improve agriculture sustainability.
Published Unlocking the world of bacteria



Bacteria possess unique traits with great potential for benefiting society. However, current genetic engineering methods to harness these advantages are limited to a small fraction of bacterial species. A team has now introduced a novel approach that can make many more bacteria amenable to genetic engineering. Their method, called IMPRINT, uses cell-free systems to enhance DNA transformation across various bacterial strains.
Published The on-and-off affair in DNA



Researchers have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via the interactions of two other proteins and histone marks. The molecular mechanisms demonstrate that rather than functioning as a simple 'off switch,' H3K9 methylation is more like a 'dimmer switch' that fine-tunes DNA transcription. The discovery suggests there might be similar mechanisms in other organisms, too.
Published Slipping a note to a neighbor: The cellular way



Study reveals how drug molecules bind in channels between neighboring cells, changing intercellular communication.
Published Towards non-toxic antifouling agents: A novel method for total synthesis of scabrolide F



Norcembranolide diterpenes, isolated from the soft corals of the genus Sinularia, are important compounds for the development of new drugs, owing to their diverse biological activities. However, total synthesis methods for these compounds are scarce. Now, a team of researchers has achieved the total synthesis of scabrolide F, a norcembranolide diterpene. They also revealed its non-toxic antifouling properties. This novel method can lead to the development of new drugs and antifouling agents.
