Privacy experts have created an AI algorithm that automatically tests privacy-preserving systems for potential data leaks.

Extreme heat often follows tropical cyclones, which can complicate disaster recovery even further, researchers have found.

For centuries, Indigenous communities in the American Southwest imported colorful parrots from Mexico. But according to a recent study, some parrots may have been captured locally and not brought from afar. The research challenges the assumption that all parrot remains found in American Southwest archaeological sites have their origins in Mexico. It also presents an important reminder: The ecology of the past can be very different from what we see today.

Aerospace and mechanical engineers have developed a machine-learning assisted superfast new way to create high-performance, energy-saving thermoelectric devices.

As low Earth orbit becomes more cluttered, it becomes increasingly necessary to use middle Earth orbits, and radiation-tolerant cell designs will be needed. Making photovoltaics thinner should increase their longevity because the charge carriers have less far to go during their shortened lifetimes. Scientists propose a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. Compared to thicker cells, nearly 3.5 times less cover glass is needed for the ultra-thin cells to deliver the same amount of power after 20 years of operation.

A litany of negative environmental pressures have had little to no effect on sand dollars and heart urchins in the Florida Keys, a new study shows. Scientists arrived at this unexpected conclusion after surveying 27 sites along a 20-mile stretch of coast near Long Key island. Five of the seven most common species known to inhabit the Florida Keys were present and accounted for in the survey and formed robust populations at varying depths.

Yeast is not the simple single-celled microorganism we once thought, but a competitive killer. When starved of glucose, yeast releases a toxin that will poison other microorganisms that have entered its surrounding habitat, even its own clones. This venomous phenomenon was previously unknown and contributes to our understanding of unicellular microorganism behavior, the evolution of unicellular to multicellular organisms, as well as having potentially useful applications for the food industry.

Computer simulations by Rice University scientists and their collaborators are the first to integrate a model of planet formation and evolution that explains two puzzling observations of exoplanets orbiting distant stars: the rarity of worlds about 1.8 times larger than Earth and the near-identical size of adjacent planets in hundreds of planetary systems.

The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to advanced alteration and metamorphism. Stromatolites, layered organo-sedimentary structures reflecting complex interplays between microbial communities and their environment, have long been considered key macrofossils for life detection in ancient sedimentary rocks; however, the biological origin of ancient stromatolites has frequently been criticized.

Subduction zones, where one tectonic plate slides beneath another, produce the most devastating seismic, volcanic, and landslide hazards on the planet. A new report presents an ambitious plan to make major advances in understanding subduction zone hazards by bringing together a diverse community of scientists in a long-term collaborative effort, deploying new instrumentation in subduction zones, and developing more sophisticated and accurate models.

To find out how different aspects of music influence the body, researchers turned a live electronic music concert into a lab study. By introducing levels of bass over speakers that were too low to hear and monitoring the crowd's movements, scientists found that people danced 11.8 percent more when the very low frequency bass was present.

Woody climbing plants, known as lianas, are more likely to infest smaller trees in Malaysian forests and therefore stop them growing to their full potential, which may have implications for climate change.

Astronomers have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way.

Plant-derived materials such as cellulose often exhibit thermally insulating properties. A new material made from nanoscale cellulose fibers shows the reverse, high thermal conductivity. This makes it useful in areas previously dominated by synthetic polymer materials. Materials based on cellulose have environmental benefits over polymers, so research on this could lead to greener technological applications where thermal conductivity is needed.

Astronomers have discovered the closest-known black hole to Earth. This is the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1600 light-years away, offers an intriguing target of study to advance our understanding of the evolution of binary systems.

A signature in the X-ray light emitted by a highly magnetized dead star known as a magnetar suggests the star has a solid surface with no atmosphere.

The island of Madagascar -- one of the last large land masses colonized by humans - -sits about 250 miles (400 kilometers) off the coast of East Africa. While it's still regarded as a place of unique biodiversity, Madagascar long ago lost all its large-bodied vertebrates, including giant lemurs, elephant birds, turtles, and hippopotami. A human genetic study now links these losses in time with the first major expansion of humans on the island, around 1,000 years ago.

A new study finds the original crust on Mars is more complex, and evolved, than previously thought. Researchers have determined the Martian crust has greater concentrations of the chemical element silicon, which may mean Mars' original surface may have been similar to Earth's first crust.
