Medical Xpress / New paper urges caution as FDA plans to phase out animal testing in drug development
Replacing animal testing with alternate methodologies in preclinical drug trials holds potential for the development of cheaper, safer pharmaceuticals as well as alleviating animal suffering. But according to a new paper ...
Phys.org / Scientists outline case for next-generation ocean iron fertilization field trials
A team of ocean and climate researchers is calling for a new generation of carefully designed ocean iron fertilization (OIF) field trials to determine whether this marine carbon dioxide removal (mCDR) method can safely and ...
Phys.org / Imaging the Wigner crystal state in a new type of quantum material
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner ...
Phys.org / Honest or deceptive? What a new signaling model means for animal displays and human claims
For decades, scientists have tried to answer a simple question: why be honest when deception is possible? Whether it is a peacock's tail, a stag's roar, or a human's résumé, signals are means to influence others by transmitting ...
Medical Xpress / Cap-like OLED wearable could prevent hair loss, replacing bulky helmet devices
A new solution that could overcome the limitations of conventional hair-loss treatments is emerging. Heavy and rigid helmet-type phototherapy devices may soon become a thing of the past. A joint research team has developed ...
Phys.org / Where are Europe's oldest people living? What geography tells us about a fragmenting continent
For over a century and a half, life expectancy has steadily increased in the wealthiest countries. Spectacular climbs in longevity have been noted in the 20th century, correlating with the slump in infectious illnesses and ...
Tech Xplore / Training four-legged robots as if they were dogs
Over the next decades, robots are expected to make their way into a growing number of households, public spaces, and professional environments. Many of the most advanced and promising robots designed to date are so-called ...
Phys.org / Nanocrystal biohybrids harvest light to reduce N₂ gas to ammonia
Ammonia, a key part of nitrogen fertilizers, is central to sustaining global food production. However, its manufacture is also energy intensive: Ammonia production requires 2% of global energy to meet global demand. Approximately ...
Phys.org / Long-period Jupiter-like exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size ...
Tech Xplore / Extending optical fiber's ultralow loss performance to photonic chips
Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new generation of ultra-coherent ...
Medical Xpress / High-dose antioxidants linked to offspring birth defects
Antioxidants have been marketed as miracle supplements, touted for preventing chronic diseases and cancers; treating COPD and dementia; and slowing aging.
Phys.org / 'Dispersal-driven' evolution fuels diversity at the air-liquid interface
As in a batch of kombucha or a barrel of sherry, microbes can assemble into a mat-like layer at the boundary between air and liquid. In laboratory culture, the bacterium Pseudomonas fluorescens SBW25 is widely known for doing ...
