Phys.org / Early parenting shapes the brain and socio-sexual behavior, rodent study shows
Past psychology studies have consistently highlighted the importance of social bonds for survival, showing that enduring relationships are linked with a longer life expectancy, a more resilient immune system, better cardiovascular ...
Phys.org / First synthetic protein motor moves along DNA in controlled, programmable steps
Researchers from UNSW Sydney have built the first artificial protein motor capable of taking controlled, directional steps along a DNA track. The protein, dubbed Tumbleweed, moves by alternating between three "feet" that ...
Phys.org / Traces of Earth's primordial magma ocean discovered in lava from a modern volcanic eruption
In May 2018, the island of Mayotte, between Madagascar and Mozambique, began to experience a series of earthquakes that led to the discovery of an underwater volcano, now called Fani Maoré. Multiple scientific expeditions ...
Phys.org / Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they ...
Phys.org / Chemists capture structure of the elusive borylnitrene trapped in a crystal using X-ray
Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...
Phys.org / Phylogenomics reveals angel insects' ancestry, resolving century‑old 'Zoraptera problem'
Zoraptera, also known as angel insects or ground lice, are tiny termite-like insects generally found underneath bark or in decaying wood. The Zoraptera group includes a few dozen known insect species that closely resemble ...
Phys.org / Bioinspired strategy creates complex 3D curved structures via programmed shrinkage
The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces ...
Phys.org / Japan releases snowman-like asteroid image after flyby
Rare images taken by a Japanese space probe during a flyby of a near-Earth asteroid have revealed that the space rock resembled a snowman, scientists said Monday.
Phys.org / Atomic 'domino effect' found to drive phase changes in a two-dimensional crystal
Phase transformations—in which a material changes from one crystal structure to another, thereby acquiring dramatically different properties—are ubiquitous in nature. Understanding the microscopic mechanisms of these transformations ...
Phys.org / South Australian algal bloom species the world's most toxic harmful microalga yet recorded
The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.
Phys.org / Q&A: How camera-equipped homing pigeons could improve robotic vision in flight
Contrary to common assumptions, pigeons do not lock their eyes in place during flight. Instead, they make slow, subtle eye movements that may help them gather more information about their surroundings.
Phys.org / Engineers discover 'unexpected motion' in drug-delivery robots
One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. ...
