Phys.org / Too much RNA can starve cells of energy, study finds

A new study from researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has uncovered a previously unknown consequence of viral infection: Too much RNA inside a cell can disrupt its ability ...

Phys.org / 3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times

At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous ...

Phys.org / Rye reference genome uncovers diversity that could strengthen wheat breeding

Rye is not only a hardy and high-yielding crop, but also possesses a valuable gene pool for wheat breeding. An international research team led by the IPK Leibniz Institute has significantly improved the foundations for research ...

Phys.org / AI prompts offer a new tool for mapping how emotion concepts relate

How similar are "joy" and "surprise"? Conversely, how far apart are "joy" and "sadness"? We naturally organize words that express emotions—such as "happy," "afraid," and "angry"—according to similarities and differences in ...

Phys.org / 'Ecology of fear' can dramatically change the behavior of blue mussels

For a blue mussel, a good meal does not come entirely without risk. Blue mussels feed by filtering microscopic algae from seawater. But some unwelcome guests can slip in along with their food. Tiny parasite larvae can hitch ...

Medical Xpress / New metric reveals how inequality can spark epidemics despite low overall risk

Influenza spreads in a crowded barracks or prison. Ebola proliferates when per capita hospital beds plummet below typical levels in developed countries. Bedside discrimination leads some patients to die and others to survive.

Phys.org / Fine-particle pollution may undermine plants' ability to absorb carbon and conserve water

Researchers at the Faculty of Social Sciences at the University of Hong Kong (HKU) have discovered that fine particulate pollution (PM2.5) significantly impairs plants' ability to use water efficiently and absorb carbon dioxide.

Medical Xpress / Human multi-organ chip tracks breast cancer spread to bone and lung

Cancer spreading beyond the primary tumor—a process known as metastasis—is responsible for at least two-thirds of cancer deaths. Drugs targeting metastatic progression have largely failed, in part because of the lack of predictive ...

Medical Xpress / Supercentenarians have an abundance of cancer-killing immune cells

The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...

Phys.org / A viral 'loose cannon' enzyme helps phages shut down bacterial defenses

As antimicrobial resistance grows around the world, novel therapies to counter it become increasingly important. Phages—viruses that infect bacteria—are an exciting avenue of research in this regard, providing a means to ...
