How a one‑eyed creature gave rise to our modern eyes‎

There is a tiny cyclops among your oldest ancestors, and humans share these remarkable ancestral roots with all other vertebrates. Researchers from Lund University and University of Sussex have found that all vertebrates evolved from a distant ancestor that had a single eye located at the top of its head. The study, published in Current Biology, also reveals that the remnants of this so-called median eye have today become the pineal gland in our brains.

LED-powered e-nose detects multiple hazardous gases at room temperature‎

The Korea Research Institute of Standards and Science has developed a next-generation gas sensor technology that uses low-cost and safe LED light to precisely distinguish multiple hazardous gases. Compared with conventional sensors that operate at high temperatures, the new technology consumes significantly less power, offering greater cost efficiency while delivering broad applicability. It is expected to enhance gas safety across industrial settings as well as everyday environments.

Why letting museum visitors smell horse manure might be good for conservation‎

What does it take to make people genuinely care about endangered cultural heritage? According to a new study from researchers at Nagoya University and Gifu University in Japan, the answer might begin with something unexpected: the smell of horse manure. Their research, published in the Journal of Museum Education, found that structured multisensory experiences can shift public perception of heritage from something distant and extraordinary to something personally relevant.

Iron and blue LEDs synthesize natural molecules, cutting the need for expensive chiral components‎

Photocatalysts facilitate chemical reactions by absorbing light. Metal-based photocatalysts are widely used in organic synthesis due to their durability and the ability to tune their function by modifying the ligands attached to the central metal atom. Most metals used in photocatalysts, such as ruthenium and iridium, are rare and expensive. Researchers at Nagoya University, Japan, previously developed an iron-based alternative, but it required large amounts of costly chiral ligands, which act as spatial templates to determine the three-dimensional structure of chemical products.

Mother's breasts may protect a newborn from the cold—a new perspective on breast evolution‎

Humans differ from other primates due to their relatively large, permanent breasts, and their development has so far not been conclusively explained. According to a study conducted at the University of Oulu, Finland, the surface temperature of the breasts combined with their size and shape may help a newborn maintain body temperature.

Martu rangers and scientists combine forces to save an endangered marsupial‎

Deep in the heart of Martu Country lies Karlamilyi National Park. Red rock and red sand stretch as far as the eye can see. Within some of these rocky outcrops, live a small population of wiminyji (northern quolls). But they haven't always been restricted to such a small area.

Hate more common in early article comments, analysis finds‎

Comments written quickly after an article was published were more likely to contain hate and threats than those posted later. This is shown by a time analysis conducted by researchers at the University of Gothenburg of 38 million reader comments on The Guardian's website. The research is published in the journal New Media & Society.

Women, children bearing brunt of homelessness in New Zealand‎

More than half of those experiencing homelessness in New Zealand are women, often mothers of young children and living in uninhabitable housing or sharing accommodation, a researcher at the University of Otago, Wellington—Ōtākou Whakaihu Waka, Pōneke, says. The lead author of a new study, Dr. Brodie Fraser from the Department of Public Health, says 51% of those experiencing homelessness during the 2023 Census were women.

Researcher warns of structural risks at Grand Renaissance Dam putting property and lives in danger‎

A new peer-reviewed study led by Dr. Hesham El-Askary, Ph.D., professor of computational and data science at Chapman University, concludes that the saddle dam of the Grand Ethiopian Renaissance Dam shows significant vulnerabilities that if breached could threaten downstream communities, property, and infrastructure if urgent monitoring and mitigation steps are not taken.

Water supplies in rural Nepal could be cleaned by harnessing the power of the sun, scientists claim‎

A new method for cleaning household water supplies in rural communities in Nepal is being developed by an international team of scientists. The solution removes harmful bacteria from the water by inserting non-toxic metal catalysts into containers which sit outside residents' homes and feed their points of supply.
