Phys.org / Deep-sea natural compound targets cancer cells through a dual mechanism
A collaborative research team has uncovered a previously unknown mechanism of action of yaku'amide B, a structurally complex peptidic natural product derived from deep-sea sponge found in the waters near Yakushima Island, ...
Phys.org / Not one ring but many: Antioxidant enzyme family can assemble in far more diverse ways than previously thought
Peroxiredoxins are among the most abundant enzymes involved in managing oxidative stress. They control the levels of peroxides such as hydrogen peroxide, relay redox signals, and help protect other proteins during stress. ...
Phys.org / Bacteria that generate electricity: How a shellfish-based gel could monitor wastewater and food
Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a target substance, or analyte. These types of sensors offer many advantages over other types of biosensors ...
Phys.org / New Panama tree species identified after 25 years is already endangered
In 2000, a group of STRI botanists collected samples of all the plants from the genus Clusia they could find in Panama to find out how the different species in this group are related.
Phys.org / Saturday Citations: Neurology of boring sounds; one huge croc; Travels With Sol
The More You Know: This week, researchers successfully reconstructed videos from the brain activity of mice. According to a new study, female birds are more likely to sing when their extended families help with childcare. ...
Phys.org / Eaton fire sent a pollution wave across Los Angeles, study shows
The 2025 Eaton fire's smoke did more than darken the sky: It generated a carbon monoxide and particulate matter surge that far exceeded Los Angeles County's average daily human-caused emissions, according to a new study led ...
Phys.org / Study documents record 118-kilometer dispersal by young female fisher in New Hampshire
Researchers at the University of New Hampshire have documented the farthest trek of a young female fisher (Pekania pennanti) moving 118 kilometers (over 73 miles) from Durham to the outskirts of Lincoln, a small town in New ...
Phys.org / Cell death in photoreceptor cells is reversible, study finds
Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, retinitis pigmentosa and retinal ...
Phys.org / Can plants count? Study suggests they can track the number of events they experience
It's long been assumed that for an organism to learn, remember or draw conclusions, it needs a brain. But mounting evidence, including a recent Cognitive Science study, challenges that assumption, suggesting that neurons ...
Phys.org / How an unlikely all-female clonal fish species copied and pasted itself free from extinction
The tiny Amazon molly (Poecilia formosa) has always fascinated researchers because, according to the rules of evolution, it shouldn't have survived as a species, let alone thrive as a species for over 100,000 years. Using ...
Phys.org / Quantum dots generate entangled photon pairs on demand
For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment surrounding a single quantum ...
Phys.org / Quantum computers must overcome major technical hurdles before tackling quantum chemistry problems
Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, published in Physical ...
