Phys.org / The same immune cells play opposing roles in tissue regeneration's balancing act
In a study of fingertip regeneration, a team led by JAX senior research scientist James Godwin found that some immune cells in mice can attack and kill cells needed to rebuild bone, while a subset of those same immune cells ...
Phys.org / Fraudulent paper mills may be manipulating scientific citations and amplifying unreliable findings
The likely manipulation of citation numbers by research paper mills in high-impact cancer journals has been uncovered by an international team of academic researchers. Their findings point to an organized campaign to inflate ...
Phys.org / Quantum sensor could measure how Earth drags spacetime
Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts ...
Phys.org / Finding new ways to catch a thief—via intruders' airborne eDNA
Environmental DNA (eDNA) is increasingly being investigated by forensic scientists as a tool to help solve criminal cases that lack biological traces—and attention is also turning to collecting trace airborne eDNA left behind ...
Phys.org / India's cobras share genetic ties across the mainland, while Sri Lankan cobras form a distinct genetic lineage
The spectacled cobra (Naja naja) is one of India's "big four" snakes responsible for most serious snakebite cases. It is currently considered one species, which lives across much of South Asia, with regional differences in ...
Phys.org / Better together? Coral fusion could throw bleached reefs a lifeline
When corals are stressed by pollution, high water temperatures or other environmental changes, they can lose the microscopic algae living inside them and on which they depend for food. As a result, they turn white, a phenomenon ...
Phys.org / Fatal Neanderthal wound may be earliest evidence of a wooden spear attack on a human ancestor
A round hole in the shoulder blade (scapula) of a Neanderthal whose partial remains were unearthed in a cave in Iraqi Kurdistan may be the earliest known example of lethal interpersonal violence with a wooden spear in the ...
Phys.org / Why tightly confined water's response to electric fields depends on direction
Using an advanced new mathematical model, a pair of physicists in Belgium has revealed the origins of an unusual, direction-dependent effect found in water confined to a narrow gap between two plates. Through research published ...
Phys.org / Drowned 5,000-year-old forests reborn as thriving peat reefs and biodiversity hotspots off Mozambique
Researchers from the Bazaruto Center for Scientific Studies (BCSS) Ocean Observatory have documented ancient forests that grew on the Mozambican coast thousands of years ago and have been found beneath the sea, where they ...
Phys.org / Fossil footprints reveal how dinosaur ancestors gradually shifted from sprawling to upright walking
A research team led by Dr. Lorenzo Marchetti of the Museum für Naturkunde Berlin described the earliest archosauriform footprints (Pachychirotherium gardenaensis) from the GEOPARC Bletterbach—UNESCO World Heritage Dolomites, ...
Phys.org / Global ice-cliff survey tests disputed theory behind projections of accelerated sea level rise
A new study led by the Woods Hole Oceanographic Institution (WHOI) provides the most comprehensive observational analysis yet of the towering ice cliffs that fringe Earth's ice sheets, giving scientists new evidence to evaluate ...
Phys.org / White Sands footprints suggest humans experienced abrupt environmental shifts during the last ice age
Expanded excavations at White Sands National Park in New Mexico have provided researchers an opportunity to refine the age of the oldest human footprints in North America and establish a deeper understanding of the landscape ...
