Phys.org / Missing methane: Countries may be underestimating wastewater greenhouse gas emissions
The amount of greenhouse gases produced by the wastewater sector may be higher than reports suggest. According to a paper published in the journal Nature Climate Change, countries are missing out on reporting a significant ...
Phys.org / Bioengineered neuronal 'circuit board' mimics conditions of the human brain
A new bioengineered neuronal circuit board "BioConNet" allows scientists to artificially engineer human brain-like wiring at scale and can be used to engineer any possible circuit. The fully programmable, open-source system ...
Phys.org / Svalbard polar bears gained fat despite rapid Barents Sea ice loss
Their icy hunting grounds are rapidly shrinking, but polar bears in Norway's remote Svalbard archipelago have defied the odds by bulking up instead of wasting away, a study said Thursday.
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 / 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 / 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 / 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 / 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 / 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 / Beam-spin asymmetry study puts proton models to the test
Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as easy. It requires peeling ...
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 / 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 ...
