Phys.org / Stale bread and bacteria could power a new era in green chemicals
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products ...
Phys.org / Saturday Citations: T. Rex on tiptoe; subduing unruly proteins; opinionated birds
This week, astronomers reported that one of the biggest observed stars in the universe could soon explode. A study compared long-term COVID-19 brain effects to the flu. And a new eco-friendly battery could theoretically last ...
Phys.org / Greenland's largest glacier could soon reach a tipping point, scientists say
Greenland's largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published ...
Phys.org / Metasurface-based SLM could enhance AR, VR and LiDAR performance
Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include ...
Phys.org / A new scientific discipline to ensure humanity's deep future
Will humanity extend into the far future? It's likely many of us think it should. The problem is that each of us, individually and collectively, act otherwise—we are destroying the environment and climate at every turn. ...
Phys.org / How a common fungus outsmarts drugs and our immune system
Our bodies are home to millions of fungi that, for the most part, are completely harmless. However, they can sometimes change from peaceful residents into dangerous invaders. One such is Candida parapsilosis, which normally ...
Phys.org / Could Mars soil block Earth microbes? 'Water bears' offer a clue
Tardigrades, commonly known as water bears, may be better suited by a new name: Tardiguardians of the Galaxy. Unlike the fictional ragtag team of unenthusiastic heroes, the microscopic animals are providing real insight into ...
Phys.org / Size-shifting nanoparticles successfully deliver mRNA medicine to the pancreas
In recent years, mRNA in lipid nanoparticles (mRNA–LNPs) has emerged as a promising strategy for treating numerous conditions, including COVID-19, various cancers and chronic genetic disorders. To date, this technology ...
Phys.org / Dynamical freezing can protect quantum information for near-cosmic timescales
Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information loss. Physicists have ...
Phys.org / InN thin films show transient Pauli blocking for broadband ultrafast optical switching
Recent decades have witnessed rapid advancements in high-intensity laser technology. The combination of laser irradiation and novel materials is opening exciting avenues for the design of functional materials and devices. ...
Phys.org / Luminescence dating confirms Roman-era gold mines in the Eastern Pyrenees
A study by the UAB and the University of A Coruña has succeeded in demonstrating the existence of Roman-era alluvial gold mines in the Eastern Pyrenees. The discovery was made possible by dating two samples from the infill ...
Phys.org / How immune cells spot viral RNA fast: LGP2 helps MDA5 respond to short dsRNA
A study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science Tokyo. Using cryo-electron microscopy and high-speed atomic force microscopy, they found that LGP2 ...
