Phys.org / Asteroid Ryugu's dust reveals nitrogen's slow concentration into complex molecules
Nitrogen is a key ingredient in the biomolecules that form the building blocks of life. Yet as an unbonded gas, it is far more likely to drift into space than to lock itself into solid compounds, making it difficult for astronomers ...
Phys.org / Ultrathin silicon structures can tune mid-IR light in billionths of a second
Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...
Phys.org / Himalayan glacial lakes are growing—and so is the downstream flood risk
Dozens of glacial lakes have formed across northern India in the last three decades, while existing lakes have expanded rapidly, highlighting the need to monitor a landscape reshaped by climate change.
Phys.org / 1,000 times faster operations bring reliable quantum computing a step closer
So far, quantum computers have been held back by their extreme sensitivity to errors and external disturbances. The longer a quantum operation takes, the greater the risk of computational errors.
Phys.org / 'CRISPR-Combo' system speeds regeneration of hard-to-breed perennial crops
Editing a plant's genes is only half the battle. Before a new, improved trait can ever reach a farmer's field, scientists must be able to grow a whole plant from just a few edited cells—a process that can be slow, unreliable ...
Phys.org / New pulse-train method aims to improve precision in quantum control
Quantum technologies are poised to transform fields ranging from medicine and sensing to computing and communications by manipulating the energy states of atoms and molecules. These manipulations are achieved by controlling ...
Phys.org / Rewetting peatlands may curb warming-driven CO₂ emissions
Peatlands store large amounts of carbon. However, when they are drained, they can become substantial sources of the greenhouse gas carbon dioxide (CO₂).
Phys.org / A fossil feather preserved inside dinosaur poop could help explain why birds survived the mass extinction
About 66 million years ago, a dinosaur—maybe a T. rex or a Nanotyrannus—ate a bird. The record of that meal, in the form of fossilized poop, has survived to today, preserving the best example of a feather ever found from ...
Phys.org / Bringing hidden optical imperfections to light
Tiny manufacturing imperfections in optical components normally go unnoticed. Yet they can alter light in surprisingly significant ways. An international research team led by TU Darmstadt has shown that such imperfections ...
Phys.org / Injectable nanodevices could provide effective treatment for drug-resistant glioblastoma
Glioblastoma is one of the most aggressive and treatment-resistant brain cancers known to medicine, carrying a median survival of just 12–15 months, even with the best available care.
Phys.org / Interviewing with AI? Try not to let the robot affect your behavior
A firm handshake used to be all a job candidate needed to make a good first impression, but today a growing number of firms are relying on artificial intelligence to screen applicants.
Phys.org / Northern map turtles leave Lake Erie before algal blooms peak, tracking finds
Harmful algal blooms pose serious threats to people, animals and the environment. The University of Toledo's Dr. Jeanine Refsnider counts it as a positive discovery that northern map turtles tend to steer clear, as she and ...
