Phys.org / Kangaroos chart 'upside-down' evolution
New research led by Flinders University argues thick tooth enamel helped kangaroos chart an unconventional evolution story, compared to the animals of other continents. A 50-million-year natural "experiment" among Australia's ...
Phys.org / Tiny flexible lasers enable force sensing inside living cells
Researchers have developed tiny flexible lasers that can be used to measure forces inside living cells. The new lasers could help illuminate various biological processes, including those involved in early development and ...
Phys.org / Soil fertilization with Amazonian dark earth increases tree diameter by up to 88%
A study conducted in the Brazilian state of Amazonas has demonstrated that small amounts of Amazonian dark earth (ADE)—an anthropogenic soil created by ancient Amazonian populations—can increase the height and diameter of ...
Medical Xpress / A new algorithm can spot who may be headed for self-harm before warning signs become obvious
Depression, one of the most widespread mental health disorders, is characterized by a persistent low mood and a loss of interest in everyday activities, along with possible sleep disruptions and/or changes in appetite. Some ...
Phys.org / Rare Tyrian purple reveals elite Roman infant burials in York
Two infants buried in Roman York were laid to rest in costly purple cloth normally reserved for emperors and members of the aristocracy, new research reveals. The babies were wrapped in a fine textile of Tyrian purple embellished ...
Phys.org / Atlantic Forest's top predator faces a hidden collapse, and protected areas are no longer enough
In addition to habitat loss and illegal hunting, the jaguar (Panthera onca) faces another threat that increases its risk of extinction in the South American Atlantic Forest: food scarcity. A study by Brazilian researchers ...
Tech Xplore / Ultralight carbon fiber lattices achieve aluminum-level performance at a fraction of the weight
Researchers at Seoul National University have developed a new class of ultralight structural materials that combine the load-bearing strength of engineering materials with the weight of foam. Using a method called 3D node ...
Phys.org / Carbon credits have enabled vital protection of tropical forests—despite being oversold 10-fold
A major analysis led by the University of Cambridge has found that many REDD+ projects achieved meaningful reductions in forest loss—offering real environmental benefits. This is despite the study confirming that almost 11 ...
Phys.org / A new interface to study RNA biology
Scientists at Université de Montréal's Institute for Research in Immunology and Cancer have developed a new database that integrates the molecular structure of microRNAs and messenger RNAs to systematically model their interactions. ...
Medical Xpress / Brazilian tree compounds block SARS-CoV-2 at multiple stages, lab tests show
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus ...
Medical Xpress / An endurance limit that surfaces in punishing races may begin at birth
A new study is raising questions about whether human endurance has biological limits shaped long before adulthood—possibly beginning at birth. Researchers are examining whether birth weight, a known risk factor for disease ...
Tech Xplore / Overlooked 'in-between' materials could reshape solar fuel and battery design
Researchers have identified previously unknown materials, including a new form of a widely studied clean-energy material, by carefully controlling and tracking how molecular precursors break down during heating.
