Phys.org / Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST ...
Dialog / Can we observe Earth-like exoplanets from our own planet?
Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of ...
Phys.org / Water-window X-rays without a synchrotron: How graphite flakes could shrink bioimaging tools
Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window." This new method holds promise in making bioimaging ...
Phys.org / Simultaneously decoding the transcriptome, epigenome and 3D genome within a single cell
The origin of many diseases begins at the cellular level and involves multiple molecular interactions. However, previous methods have struggled to accurately observe changes in individual cells. Analyzing average values across ...
Phys.org / Large area MoS₂ reduces energy loss in magnetic memory films
Scientists at the University of Manchester have discovered that placing magnetic films on atomically thin molybdenum disulfide (MoS₂) fundamentally changes how they lose energy, a finding that could bring 2D‑material ...
Phys.org / Meet 'Tous'—an entirely new genus of mammal
Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people picture biodiversity, ...
Phys.org / Recreating the forms and sounds of historical musical instruments
What if there were a way to create accurate replicas of ancient and historical instruments that could be played and heard?In late 2024, senior MIT postdoc Benjamin Sabatini wrote MIT Professor Eran Egozy to ask just that, ...
Phys.org / A new 'molecular switch' for inborn immunity identified
Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which ...
Phys.org / Light-guided 'optovolution' evolves proteins that switch states on schedule
EPFL researchers have developed a light-based method that can produce proteins that switch states, respond to signals, and even compute, using light and the cell cycle.
Phys.org / X-raying rocks reveals their carbon-storing capacity
To avoid the worst effects of climate change, many billions of metric tons of industrially generated carbon dioxide will have to be captured and stored away by the end of this century. One place to store such an enormous ...
Phys.org / The 'Great Texas Freeze' killed thousands of purple martins: Biologists worry recovery could take decades
Thousands of birds, including beloved purple martins, died in "The Great Texas Freeze" of 2021. A study published in Nature Ecology & Evolution led by biologists at the University of Massachusetts Amherst, reveals not only ...
Phys.org / Toward practical laser-driven light sails using photonic crystals
Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. ...
