Phys.org / Porpoises can 'turn down the volume' to withstand ship noise
Porpoises are entirely dependent on their hearing for survival. They navigate, hunt, and communicate by emitting rapid click sounds and listening to the returning echoes. However, with increasingly noisy oceans, it is getting ...
Phys.org / Chemists create complex DNA structures without hydrogen bonds
No "sticky ends"? No problem. A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature Communications, turns a fundamental ...
Phys.org / Greenhouse gas fluxes in Everglades provide path for maximizing carbon capture via water management
The Florida Everglades is a complicated climate actor. The 1.5-million-acre wetland system remains a carbon sink, removing an average of 13.7 million metric tons of carbon dioxide from the atmosphere each year, but the system ...
Phys.org / Large land predators were hunting big plant-eaters more than 280 million years ago, study finds
A study examining fossil evidence shows that large land predators were already hunting big plant-eating animals more than 280 million years ago. University of Toronto Mississauga researchers Jordan M. Young, Tea Maho, and ...
Phys.org / Research reveals cosmic tug-of-war behind the Crab Pulsar's zebra stripes
For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating from the Crab Pulsar, the remnant of a supernova observed by Chinese and Japanese astronomers in the ...
Phys.org / Feral horses and cattle create more resilient nature, rewilding study reveals
Protected natural areas across Europe are changing. Climate change, with rising temperatures and heavy rainfall, is turbocharging the growth of shrubs and trees, choking the flowers and insects that need the light and heat ...
Phys.org / Agrivoltaics can increase or reduce yields and profits, depending on the crop and where the systems are deployed
In a world where increasing demands for food security and energy strain existing resources, scientists are looking for new ways to maximize both. One potential option, agrivoltaics, integrates solar photovoltaics with crops. ...
Phys.org / Isolating vesicle-cloaked viruses in city and hospital wastewater
Viruses such as human norovirus can travel in vesicles, small fluid-filled sacs that are like shipping containers for cells. Viruses hidden in these containers are often harder to detect and may be more infectious than free-floating ...
Phys.org / Self-propelling microbes switch up swimming strategy to optimize light intake
Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive. Reporting in Physical Review ...
Medical Xpress / Supposedly harmless peptide may be linked to Alzheimer's disease
While companies developing drugs to treat Alzheimer's disease have spent decades and many billions of dollars targeting amyloid beta due to its role in clogging patients' brains with harmful deposits, a biochemist at the ...
Phys.org / Oman ophiolite study suggests subduction zones can lock away CO₂
A research team led by a Keele scientist has shed new light on how a mysterious rock formation in Oman was created, which could reveal new details about Earth's ability to store carbon dioxide (CO2). The study, led by Dr. ...
Medical Xpress / Targeting the untargetable cancer—rezatapopt, an oral p53 reactivator
Memorial Sloan Kettering Cancer Center investigators and collaborators have tested rezatapopt, an oral p53 reactivator designed for tumors with TP53 Y220C, and observed antitumor activity across multiple solid tumor types ...
