Mapping marine megafauna on the high seas
A Western Australian scientist has compiled the largest global dataset ever on the travel habits of large marine animals. The collaboration involves hundreds of researchers from around the world and...
Checklist of Pa. bees documents 49 new species and some that may be endangered
A study documenting bees that are reported to occur in Pennsylvania has found the presence of 437 species, including 49 never before recorded in the state. Researchers said the resulting...
Controlling plants with the power of colored light
Scientists have found a way to control different plant processes -- such as when they grow -- using nothing but colored light. The development reveals how colored light can be...
A histone modifier that facilitates an epigenetic switch
Epigenetic regulation of gene expression is associated with switching between chromatin states characterized by distinct histone modifications.
Raw milk may do more harm than good
Raw or unpasteurized cows' milk from U.S. retail stores can hold a huge amount of antimicrobial-resistant genes if left at room temperature, according to a new study.
California enters a perilous phase as coronavirus spread intensifies
Officials express alarm over people flouting safety rules as the state records its highest number of new coronavirus cases reported in a single day.
Researchers look for answers as to why western bumblebees are declining
A University of Wyoming researcher and her Ph.D. student have spent the last three years studying the decline of the Western bumblebee. The two have been working with a group...
Scientists urge business and government to treat PFAS chemicals as a class
All per- and polyfluorinated substances (PFAS) should be treated as one class and avoided for nonessential uses, according to a peer-reviewed article published today in Environmental Science & Technology Letters.
Researchers look for answers as to why western bumblebees are declining
The decline of the Western bumblebee is likely not limited to one culprit but, instead, due to several factors that interact such as pesticides, pathogens, climate change and habitat loss.
Newsom threatens to reverse California reopening as coronavirus spreads
Gov. Gavin Newsom said the state is prepared to reinstate restrictions of his stay-at-home order as cases of the coronavirus continue to increase in California.
Declining eyesight improved by looking at deep red light
Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new study, the first of its kind in humans.
Producing a gaseous messenger molecule inside the body, on demand
Nitric oxide is an important signaling molecule in the body, with a role in building nervous system connections that contribute to learning and memory. It also functions as a messenger...
Researcher tackles long-standing mysteries about membrane protein structure
Ion channels and membrane transporters are in the business of moving ions and small molecules across cellular membranes. They are essential for metabolic and cellular homeostasis, and for a host...
Osmotic stress identified as stimulator of cellular waste disposal
Cellular waste disposal, where autophagy and lysosomes interact, performs elementary functions, such as degrading damaged protein molecules, which impair cellular function, and reintroducing the resulting building blocks such as amino...
New leaders emerge as organizations go to virtual work spaces, says study
When work meetings shifted online this spring, some may have noticed new standouts among their colleagues. According to new research, members of virtual teams identify leaders in significantly different ways...
Researchers discover unknown consumer base for unsustainable bear product use
In their efforts to better understand ongoing wildlife trafficking and the dynamics of unsustainable bear product use by consumers in Cambodia, a team of researchers led by San Diego Zoo...
New 3D model shows how the paradise tree snake uses aerial undulation to fly
For more than 20 years, a biomedical engineering and mechanics professor has sought to measure and model the biomechanics of snake flight and answer questions about them, like that of...
Engineers use 'DNA origami' to identify vaccine design rules
Using DNA origami as a virus-like scaffold, researchers designed an HIV-like particle that provokes a strong response from human immune cells grown in the lab. They are now testing this...
Bioengineered uteri support pregnancy
Scientists were able to show that bioengineered uteri in an animal model developed the native tissue-like structures needed to support normal reproductive function.
Worldwide slowdown in fishing unlikely to save rare species
Commercial fishing taking place worldwide has dipped since the start of the coronavirus pandemic, but scientists and conservation experts say it's unclear if the slowdown will help endangered species of...
Engineered immune cells recognize, attack human and mouse solid-tumor cancer cells
CAR-T therapy has been used successfully in patients with blood cancers such as lymphoma and leukemia. It modifies a patient's own T-cells by adding a piece of an antibody that...

Newly designed ligands for a catalytic reaction to synthesize drugs and useful compounds
Currently, various therapeutic compounds on the market, such as proteins, enzymes, and amino acids, are 'chiral compounds'—molecules with two structures that are mirror images of each other but cannot be...
Study shows antibiotic resistance genes persist in E. coli through 'genetic capitalism'
We have known for some time that over-use of antibiotics is causing a frightening increase in antibiotic resistance in bacteria, through the rapid spread of antibiotic resistance genes. What may...
