Phys.org / Plant DNA harbors virus 'fossils' that reflect 300 million years of evolution
Is it possible to study the history of viruses that emerged several hundred million years ago? An international team of INRAE and CIRAD researchers answered this question by exploring plant genomes to find the molecular fossils ...
Medical Xpress / Men should speed up slower to avoid 'hitting the wall' in marathons, new research suggests
Male runners may be twice as likely as female runners to suddenly slow down—known as "hitting the wall"—during a marathon, according to a study published in Scientific Reports. The authors suggest that men may be able to ...
Phys.org / 400-year-old painting reveals a bat's secret diet
Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As ...
Phys.org / How a giant planet survived its star's death, then migrated inward
When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star's violent demise. Now, observations from NASA's James Webb Space Telescope (JWST) may finally explain the planet's ...
Tech Xplore / Giving drones a sense of 'pain' could help them predict instability before it happens
Imagine you're running and you sprain your ankle. The pain makes you gingerly limp the rest of the way home. This is a great example of how nature adapts to failures in a system. The pain tells you: "If you continue running ...
Phys.org / Last-minute launch problem delays satellite rescue mission for NASA
A rush rescue mission to save a NASA space telescope remains grounded, this time because of a last-minute launch problem.
Phys.org / Quantum properties of multimode light observed despite extreme losses
Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to a detector can make them invisible, limiting their use outside carefully controlled environments. ...
Medical Xpress / Precision fMRI maps prefrontal cortex in individuals, revealing fine-scale structures
Much like camera settings—filters, flashes and focus—affect what we notice in a final photo, the way scientists measure something can affect how we interpret and understand it. This is especially true when imaging things ...
Phys.org / Algae may have launched coral reefs by hijacking coral cells, genetic experiments suggest
The reefs scattered throughout the tropics arose only after algae took up full-time residence in coral cells, supplying corals with abundant food and enabling them to build extensive shallow-water communities. But with warming ...
Medical Xpress / Biomarker-matched drug combos shrink treatment-resistant melanoma in preclinical models
A new study led by researchers at The University of Texas MD Anderson Cancer Center has identified a way to tailor drug combinations based on specific tumor biology to improve outcomes for treatment-resistant advanced melanoma.
Phys.org / Hidden role of garnet reveals how Earth's 660-km seismic boundary forms
Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle ...
Phys.org / A WRAP for biology's greasiest problem
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly ...
