Astronomers find hidden trove of massive black holes

Posted: 24 May 2022 07:05 AM PDT

Astronomers have found a previously overlooked treasure trove of massive black holes in dwarf galaxies. The newly discovered black holes offer a glimpse into the life story of the supermassive black hole at the center of our own Milky Way galaxy.

Charting a safe course through a highly uncertain environment

Posted: 23 May 2022 12:06 PM PDT

Researchers have developed a trajectory-planning system for autonomous vehicles that enables them to travel from a starting point to a target location safely, even when there are many different uncertainties in the environment, such as unknown variations in the shapes, sizes, and locations of obstacles.

Twisted soft robots navigate mazes without human or computer guidance

Researchers have developed soft robots that are capable of navigating complex environments, such as mazes, without input from humans or computer software.

Skydiving salamanders live in world's tallest trees

Posted: 23 May 2022 08:55 AM PDT

Researchers have documented in a vertical wind tunnel the amazing ability of one species of salamander -- which spends its entire life in the tops of redwoods -- to parachute, glide and maneuver in mid-air. Ground-dwellers, on the other hand, freak out during free-fall. The salamander's skydiving skills are likely a way to steer back to a tree it has fallen or jumped from to avoid terrestrial predators.

Noisy jackdaw birds reach 'consensus' before taking off

Posted: 23 May 2022 08:55 AM PDT

On cold, dark winter mornings, small black crows known as jackdaws can be heard calling loudly to one another from their winter roosting spots in the U.K. before taking off simultaneously right around sunrise. Now, researchers who've studied their daily activities in unprecedented detail report evidence that these groups of hundreds of individuals rely on a 'democratic' decision-making process to coordinate with one another and take to the skies all at once.

Planets of binary stars as possible homes for alien life

Posted: 23 May 2022 08:55 AM PDT

Nearly half of Sun-size stars are binary. According to new research, planetary systems around binary stars may be very different from those around single stars. This points to new targets in the search for extraterrestrial life forms.

The limits of vision: Seeing shadows in the dark

Posted: 23 May 2022 08:54 AM PDT

A specific retinal pathway enables mice to detect incredibly dim shadows -- nearly reaching the limit of what's physically possible. The same circuit is in human eyes, which might enable researchers to probe visual diseases at unprecedented resolution.

A family of termites has been traversing the world's oceans for millions of years

Posted: 23 May 2022 07:22 AM PDT

A comprehensive family tree, based on DNA sequences, has revealed that drywood termites have made at least 40 oceanic journeys over the last 50 million years to reach far flung landmasses.

Möbius band constructed solely by carbon atoms

A team has synthesized a belt-shaped molecular nanocarbon with a twisted Möbius band topology, i.e., a Möbius carbon nanobelt.

Ancient tooth unlocks mystery of Denisovans in Asia

Posted: 17 May 2022 06:04 PM PDT

What links a finger bone and some fossil teeth found in a cave in the remote Altai Mountains of Siberia to a single tooth found in a cave in the limestone landscapes of tropical Laos? The answer to this question has been established by an international team of researchers from Laos, Europe, the US and Australia. The human tooth was chanced upon during an archaeological survey in a remote area of Laos. The scientists have shown it originated from the same ancient human population first recognised in Denisova Cave (dubbed the Denisovans), in the Altai Mountains of Siberia (Russia).
