Tech Xplore / We may never be able to tell if AI becomes conscious, argues philosopher
A University of Cambridge philosopher argues that our evidence for what constitutes consciousness is far too limited to tell if or when artificial intelligence has made the leap—and a valid test for doing so will remain ...
Phys.org / Scientists build a quantum computer that can repair itself using recycled atoms
Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But scientists at the US-based ...
Phys.org / Beachy Head Woman's origin story: DNA analysis reveals she was local to southern Britain
The identity of a Roman-era individual found in southern England has finally been resolved after scientists at the Natural History Museum were able to sequence high quality DNA from her skeletal remains.
Phys.org / Candida auris: Genetic process offers new treatment target for deadly fungal disease
Scientists have discovered a genetic process which could unlock new ways to treat a mysterious and deadly fungal infection which has shut down multiple hospital intensive care units.
Phys.org / 13 years of detailed US CO₂ emissions data released
New research from Northern Arizona University shows detailed CO2 emissions for the United States from 2010 to 2022.
Phys.org / Neutrality isn't a safe strategy on controversial issues, research shows
Researchers Rachel Ruttan and Katherine DeCelles of the University of Toronto's Rotman School of Management are anything but neutral on neutrality. The next time you're tempted to play it safe on a hot-button topic, their ...
Phys.org / UK's worst-case climate risks laid bare for lawmakers
British policymakers planning for climate change now have detailed worst-case scenarios at their disposal, filling a gap that left the UK unprepared for extreme outcomes.
Phys.org / Ancient hunter-gatherer DNA may explain why some people live to 100 years or more
Our hunter-gatherer ancestors have given us many things. They passed down mastery of fire for cooking and early survival technologies, such as stone tools. They may also have given us the secret to a long life. A new study ...
Phys.org / Global peatlands revealed as critical frontier in fight against climate change
Global peatlands—huge expanses of partially decayed vegetation—store more carbon than is naturally present in the atmosphere but are under pressure from drainage-based agriculture. New research from Murdoch University ...
Phys.org / Hidden clay intensified 2011 Japan megaquake, study confirms
An international research expedition involving Cornell has uncovered new details as to why a 2011 earthquake northeast of Japan behaved so unusually as it lifted the seafloor and produced a tsunami that devastated coastal ...
Phys.org / Silicon atom processor links 11 qubits with more than 99% fidelity
In order to scale quantum computers, more qubits must be added and interconnected. However, prior attempts to do this have resulted in a loss of connection quality, or fidelity. But, a new study published in Nature details ...
Phys.org / California on track for lowest Lake Mead use in 75 years
Lake Mead may be facing historic shortages, but officials from the Colorado River state that uses the most water are celebrating unprecedented water savings.
