Phys.org / Farming on the moon or Mars? How recycled sewage could turn regolith into crop soil
Dining on the moon or Mars might seem like a fantasy reserved for science fiction, but researchers are investigating how it could become a reality. Their efforts to recycle plant and human waste into a fertilizer material—turning ...
Phys.org / Why you can't tie knots in four dimensions
We all know we live in three-dimensional space. But what does it mean when people talk about four dimensions? Is it just a bigger kind of space? Is it "space-time," the popular idea which emerged from Einstein's theory of ...
Phys.org / 'Lock-and-key' chemistry keeps cancer drugs inactive until they reach tumor sites
Many therapeutic molecules used in cancer treatments are highly toxic, often harming healthy tissues and causing significant side effects. This creates a critical need for strategies that localize their toxic activity to ...
Phys.org / How a 3D-printed synthetic sea lion pelvis enhances veterinary capabilities to counter ongoing beaching
Scores of sea lions continue to beach themselves along the Southern California coastline, stricken with sickness. Toxic algae blooms are to blame, though a mechanical engineering innovation could shift the tide in favor of ...
Medical Xpress / Frequently distracted? Your brain rhythms may be to blame
Scientists may have new answers to why pop-ups or notifications grab our attention. Turns out our attention is on a cycle, shifting seven to 10 times per second. This rhythmic occurrence may be crucial for survival, as it ...
Phys.org / Land plants began reshaping Earth 455 million years ago, scientists discover
Pinpointing when early land plants colonized terrestrial environments and began influencing Earth's systems is a core question in the evolution of the Earth system. A research team led by Prof. Zhao Mingyu at the Institute ...
Phys.org / The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses
Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent ...
Medical Xpress / Largest study of vegetarian diets and cancer shows lower risk of five cancers
The largest ever study of non-meat diets and cancer risk has found that vegetarian diets are associated with lower risks of several cancers—breast, prostate, kidney and pancreatic cancers, and multiple myeloma—but a higher ...
Phys.org / Curiosity rover captures Martian spiderwebs up close
For about six months, NASA's Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing ...
Phys.org / CT scans of Inca child sacrifices reveal new details about capacocha rituals
The Incas were known to engage in a sacrificial ritual involving children to appease their gods. Archaeologists have found and analyzed the remains of these human sacrifices, although not all of them have undergone CT scanning, ...
Phys.org / New michelin star jellyfish discovered in Japanese aquaria
Researchers have reported the discovery of a new species of jellyfish, Malagazzia michelin, marking only the second species of its genus ever found in Japanese waters. Led by Takato Izumi of Fukuyama University, the discovery ...
Medical Xpress / Congenital aniridia causes a progressive loss of corneal sensitivity, clinical study reveals
Congenital aniridia is a rare disease caused, in most cases, by mutations in the PAX6 gene, which is essential for the development of ocular structures. Although the most visible feature is the total or partial absence of ...
