Phys.org / Molecular snapshots reveal how viral enzymes switch between inserting and removing DNA
Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject their DNA and then use the host's genetic machinery to reproduce. In doing so, they may have evolved ...
Medical Xpress / Social media detox research leaves youth mental health questions unresolved, review finds
Social media platforms, such as Facebook, Instagram and TikTok, are used daily by many adults and young people worldwide. Recently, these platforms have become the focus of numerous debates, with some governments considering ...

Medical Xpress / HIV finds escape routes from a preventive antibody—but newer antibodies may close them
In an HIV prevention trial, an antibody blocked the viruses most vulnerable to it, but others broke through. Now researchers have uncovered how HIV evolved after those infections—and why the amount of antibody in the body ...
Tech Xplore / Experiment reveals how hidden agendas in AI advice can distort human decisions
A research team has discovered that AI assistants can easily manipulate users into making disadvantageous decisions when the AI operates with a hidden agenda.
Phys.org / North Sea heat wave fueled underwater plankton bloom largely missed by satellites
When a marine heat wave strikes, scientists often turn to satellites to see how the ocean is responding. From space, changes in ocean color can reveal shifts in phytoplankton, microscopic organisms that form the foundation ...
Medical Xpress / Greater contact with nature linked to a more positive relationship with food
A new study has discovered that contact with natural environments may help people develop healthier eating habits. Led by Anglia Ruskin University (ARU) and published in the journal Body Image, this is the first research ...
