Phys.org / Learning physics can derail some students: New research shows the best way to keep them on track
For many undergraduate students, exploring the complexities of physics for the first time, from wading through advanced mathematics, to absorbing information in a large lecture format, can be a daunting endeavor—one that ...
Phys.org / You are what you eat: Cichlid fish reveal how food sources drive evolution of digestive system
Different beak and jaw shapes are illustrative examples of how animal species have adapted to different food sources. In a new study published in the journal Nature, researchers now show how diet itself shapes the composition ...
Phys.org / Even after adopting cattle, early east African herders kept hunting and gathering for 1,000 years
Eastern Africa's earliest livestock herders continued fishing, hunting and gathering for centuries after livestock were first brought to the region. The first pastoralists in eastern Africa didn't suddenly switch to a diet ...
Phys.org / 370 billion crickets are farmed for food every year. Scientists have discovered they may feel pain
You're cooking dinner, distracted, and your hand brushes a hot pan. Nerve signals race to your spinal cord and back to yank your arm away in a fraction of a second, with no thought required.
Phys.org / How wasted infrared light could boost solar panels, night vision and 3D printing
Researchers at UNSW Sydney have developed a nanoscale device that converts low-energy infrared and red light into higher-energy visible light, a breakthrough that could eventually improve solar panels, sensing technologies, ...
Phys.org / Reconfigurable Ge-Si photodetector achieves ultrahigh-speed data transmission using low-loss packaging
The rapid growth of large language models is placing increasing demands on data centers, where large volumes of data must be transferred efficiently between servers. Optical interconnects are essential for enabling this communication, ...
Phys.org / This single mother must learn quickly—or her colony won't survive
Being a single mother of 20 is no joke, especially if the survival of a whole species depends on it. A queen bumblebee faces this very challenge when she lays her first eggs in the spring: She is utterly alone, with no worker ...
Phys.org / Bilayer antiferromagnet reveals photocurrent that flips with magnetic state
In recent years, atomically thin materials—crystals only a few atoms thick—have attracted growing attention because they can exhibit physical properties that do not appear in conventional bulk materials. Among them, atomically ...
Phys.org / Mapping how 'Big AI' influences AI laws and oversight
Artificial intelligence (AI) companies influence policy and regulation using similar techniques to Big Tobacco, Big Pharma and Big Oil, according to a new study.
Phys.org / Professional chess analysis reveals faster decisions correlate with higher quality moves
In chess, faster decisions are on average of higher quality. This is the conclusion of a study that has just been published in the journal Proceedings of the National Academy of Sciences. The team of researchers, which, in ...
Phys.org / A smelly dog breath breakthrough: Plant-based spray tackles odor and harmful oral microbes
Pet owners love their dogs but may not always love the smell of their breath. Because this bad odor can signal oral disease, veterinary clinics will prescribe daily toothbrushing, antibiotics, or chemical rinses as treatment. ...
Phys.org / Worker bumble bees help determine which baby bee will become queen
Every bumble bee colony has a queen, but a new study led by researchers at Penn State suggests the process of determining which baby bee reigns supreme may be less monarchal than the royal title suggests. The study, published ...
