Tech Xplore / Microscopic image changes can bypass AI guardrails, nearly doubling unsafe responses
It may look like a picture of a panda bear to you, but to your business's AI agent, it can act like a skeleton key, bypassing safety safeguards and potentially causing the model to generate harmful, misleading or policy-violating ...
Phys.org / How thousands of nature's longest sperm squeeze into a tiny fruit fly
When Jasmin Imran Alsous peered down her microscope lens, she expected to see chaos—a mishmash of tangled cells. She was viewing the inside of a male fruit fly's sperm storage organ, using a powerful microscope at the CCBScope ...
Phys.org / New breakthrough spots deadly methanol without opening bottles
A new optical technique developed by researchers at the University of St Andrews and Adelaide University allows toxic methanol in alcoholic spirits to be detected without opening the bottle. Published in the Journal of Physics: ...
Phys.org / Crashing insect populations lead to smaller tree swallows that reproduce less
Since the 1970s, the number of insects at Canada's Long Point Bird Observatory has dropped by more than 60%, according to a new study led by the University of Michigan. Because of this, today's birds are smaller and facing ...
Phys.org / Eight ways to sleep well in hot weather
When temperatures rise, sleep often suffers. Hot nights can make it harder to fall asleep, increase waking during the night and leave people feeling less rested the next day.
Phys.org / Using less, living better: Demand-side climate action wins public support
Climate strategies are still judged largely across two dimensions: how much they cost and how many tons of CO2 they save. A new study published in Communications Sustainability argues that this narrow lens overlooks much ...
Phys.org / How cyanobacteria developed photosynthetic membranes over the course of evolution
A new study provides the first insights into how thylakoid membranes—the internal compartments where oxygen-producing photosynthesis takes place—emerged during evolution. By comparing the genomes of cyanobacteria with and ...
Phys.org / How solar wind forecasting will help define heliosphere's boundaries
Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as ...
Phys.org / Cats age like humans—could studying their brains reveal healthy aging secrets?
Domestic cats age in remarkably similar ways to humans and show comparable age-related patterns of brain deterioration, according to an international collaboration among the University of Bath in the U.K., Auburn University ...
Medical Xpress / Molecular cause of age-related cognitive decline identified
A research team from University Hospitals, Case Western Reserve University and the Louis Stokes Cleveland VA Medical Center has identified a critical molecular cause of age-related cognitive decline, potentially paving the ...
Phys.org / Simple acknowledgment boosts repeat customer participation in take-back programs
Companies may only need to send an acknowledgment message to boost repeat customer participation in recycling and reuse programs for used goods like laptops and coffee pods, according to a new study led by Penn State researchers. ...
Phys.org / Animals are often moved to make way for infrastructure, but we don't know what happens to them next
When major infrastructure projects are built in rural areas, wildlife is often displaced and moved out of the way. This is called mitigation translocation, and it is a globally recognized method for moving animals. However, ...
