Using AI to predict how bioplastics behave under heat
A new ANIPH study shows how machine learning models can predict how PHB and PHBV respond to heat, helping manufacturers design formulations that are easier to process.

Earth's orbital asymmetries share recurring rhythms with El Niño, study finds
Every few years, an unusual warming of surface waters across the central and eastern tropical Pacific—known as El Niño—reorganizes atmospheric circulation worldwide, bringing severe droughts to some continents and torrential rainfall to others. For decades, oceanographers and meteorologists have mapped the intricate internal machinery behind the El Niño–Southern Oscillation (ENSO), from shifting trade winds to subsurface ocean waves.

Engineered atomic interactions help microwave sensor capture three times as much information
Researchers from the Faculty of Physics at the University of Warsaw (UW) and the Center for Optical Quantum Technologies at the University of Warsaw's Center for New Technologies (CeNT UW) have developed a method for ultrasensitive microwave sensing. Using cold, strongly interacting Rydberg atoms as a microwave detector, the researchers observed that carefully engineered interactions between the atoms make the atomic state resistant to loss.

Not afraid of ghosts: Curiosity and fearlessness apparent in German shepherd genes
German shepherd dogs bred for working are more curious and less neurotic than German shepherds bred for show. A new study from Uppsala University and the Swedish University of Agricultural Sciences has shown that the differences are not only apparent in the dogs' behavior, but also in their genes. In previous studies, similar genes in humans have been associated with neuroticism. The research is published in the journal Animal Genetics.

Global climate policies continue to advance despite setbacks, research finds
The latest findings from the Oxford Climate Policy Monitor, led by the Blavatnik School of Government and the Oxford Sustainable Law Programme, show that progress in Asia, Africa and Latin America is more than offsetting the weakening or reversal of climate policies in parts of Europe and North America.

Product for controlling agricultural pests proves harmful to iconic banana slug
Researchers at Oregon State University say a product used to control pest slugs on farms in multiple countries is harmful to an iconic West Coast slug and that more research is needed before the product is approved for use in the United States. The work is published in the journal PLOS One.

Multiplexed detector system precisely counts more than 9,000 photons
Researchers have developed a new approach that can precisely count from zero to more than 9,000 individual photons. The advance opens new possibilities for studying quantum light at large scales and making precise optical measurements.

Parrots' vibrant feathers are surprisingly susceptible to bacterial attack
Flashy birds, from peacocks to parrots, have inspired a long tradition of using animal colors to study evolution. Colorful plumage often functions as a signal—for example, to attract a mate. Alternatively, drab colors can be used for camouflage. However, color can have functions beyond signaling and camouflage. This is because pigments, the molecules embedded in feather tissues to produce a broad range of colors, can also influence other aspects of feathers, ranging from mechanical strength to thermoregulatory properties.
