In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons, the findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical engineering.

An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.

A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of the early universe -- have discovered a new kind of antimatter nucleus, the heaviest ever detected. Composed of four antimatter particles -- an antiproton, two antineutrons, and one antihyperon -- these exotic antinuclei are known as antihyperhydrogen-4.

Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.

Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.

Researchers have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of the chaotic movements of magnetic fields and turbulent plasma gas.

Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.

James Joyce's tome 'Finnegans Wake' famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce's challenging novel stands out mathematically. Researchers compared the distribution of punctuation marks in various experimental novels to determine the underlying order of 'Finnegans Wake' and by statistically analyzing the texts, researchers found the tome exhibits an unusual but statistically identifiable structure. The wide singularity spectrum was perfectly symmetrical, meaning sentence length variability follows an orderly curve.

Our understanding of Venus' water history and the potential that it was once habitable in the past is being challenged by recent observations.

Some of the attractive hues of brightly colored, cloth-bound books from the Victorian era come from dyes that could pose a health risk to readers, collectors or librarians. The latest research on these 'poison books' used three techniques -- including one that hasn't previously been applied to books -- to assess dangerous dyes in a university collection and found some volumes had levels that might be unsafe.

A new study on 'legalese' suggests this convoluted language acts to convey a sense of authority in legal documents. The researchers also found that even non-lawyers use legalese when asked to write laws.

A new article provides a narrative review of the relevant similarities and distinctions between nonhumans and humans to assess the causes and consequences of winner and loser effects in humans.

The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
