Medical Xpress / Mirror fragments intercept Alzheimer's-causing protein
Understanding how proteins interact with their own mirror images enabled a Kobe University research team to design a small mirror protein that disables a causal factor of Alzheimer's disease, amyloid-beta.
Phys.org / Tracing the evolutionary history of chemical warfare between plants and insects
A new study published in Nature Ecology & Evolution connects plant and insect physiology, chemical ecology, molecular function, and evolutionary analysis to offer a new perspective on plant–insect coevolution. The research ...
Phys.org / 100 million years ago, an 'evolutionary fuse' was lit in the deep ocean, sparking squid diversification
From color-changing skin to jet-propelled motion, squid and cuttlefish have long fascinated scientists. To understand the origins of their unique characteristics, many attempts have been made to define their evolutionary ...
Medical Xpress / Organ-on-a-chip technology replicates decades of human aging in just four days
Over one billion people worldwide are over 60, and the population is projected to more than double by 2050. But as more people live into their 60s, 70s, and 80s, health care systems across the globe may face new challenges ...
Medical Xpress / Genetically modified marmosets as a model for human deafness provide a foundation for future gene therapies
Why are some people unable to hear from birth, even though their inner ear appears intact? One possible cause lies in the so-called OTOF gene. It plays a central role in transmitting sound signals from the hair cells to the ...
Phys.org / A global butterfly index could advance insect conservation worldwide
About 70% of the species on Earth are insects. They are fundamental components of most ecosystems: they comprise half of the biomass on the planet, pollinate flowers, decompose dead organic matter and play multiple roles ...
Phys.org / Seals use whisker movement to follow underwater trails—an approach that could improve robotic sensing
Seals are carnivorous marine mammals that are well adapted to hunting for fish underwater, where visibility is poor. In such conditions, seals rely on their highly sensitive whiskers to detect tiny water movements left behind ...
Phys.org / Study explains Antarctic sea ice growth and sudden decline
A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.
Phys.org / Bacteria invent another way to turn on genes
In their landmark 1961 paper on the lac operon, Nobel laureates François Jacob and Jacques Monod speculated that RNA might control gene activity in bacteria through base-pairing interactions. But once protein transcription ...
Medical Xpress / Common disinfectant chemicals far more toxic when inhaled, study finds
Breathing in common disinfectant chemicals known as quaternary ammonium compounds, or QACs, may be far more harmful than swallowing them, according to a mouse study led by researchers at the University of California, Davis. ...
Medical Xpress / New Zealand study finds a significant rise in sepsis cases
Hospital admissions for sepsis rose significantly between 2000 and 2019, with infants, people over 70, Māori and Pacific peoples and those living in areas of deprivation at much higher risk of developing the condition, researchers ...
Phys.org / Could a solar storm derail the Artemis II mission?
Every mission to deep space is fraught with danger. A hardware failure during launch, an equipment malfunction far from Earth, or a small space rock hitting the vehicle are all scenarios astronauts will train for.
