Study says tech firms underreport their carbon footprint
Large technology companies such as SAP, IBM and Google are underreporting their greenhouse gas emissions at a time of heightened scrutiny over the role of corporations in driving climate change, a study released Friday claimed.
Big tech data centers spark worry over scarce Western water
Conflicts over water are as old as history itself, but the massive Google data centers on the edge of this Oregon town on the Columbia River represent an emerging 21st century concern.
NASA targeting Feb. 2022 to launch new lunar program Artemis
NASA said Friday it is now targeting February 2022 for the uncrewed lunar mission Artemis 1, the first step in America's plan to return humans to the Moon later this decade.
How can lizards adapt to a changing climate?
Researchers at the University of Toronto and Ohio Wesleyan University are collaborating in a quest to find out how lizards can adapt to the world's changing climate.
Seamless wayfinding by a deafblind adult on an urban college campus: A case study
Portland State University researchers Martin Swobodzinski and Amy Parker, with student co-authors Julie Wright, Kyrsten Hansen and Becky Morton, have published a new article in Frontiers in Education: "Seamless Wayfinding by a Deafblind Adult on an Urban College Campus: A Case Study on Wayfinding Performance, Information Preferences, and Technology Requirements."
Nature-inspired coatings could power tiny chemistry labs for medical testing and more
A newly developed coating that allows for certain liquids to move across surfaces without fluid loss could usher in new advances in a range of fields, including medical testing.

Machine learning predicts antibiotic resistance spread
- ScienceDaily
- 21/10/22 23:15
Genes aren't only inherited through birth. Bacteria have the ability to pass genes to each other, or pick them up from their environment, through a process called horizonal gene transfer, which is a major culprit in the spread of antibiotic resistance.
Experiments confirm a quantum material’s unique response to circularly polarized laser light

A new study reveals the specific molecular mechanism that controls the transition from acute to chronic pain, and identifies this mechanism as a critical target for disease-modifying medicines.
A diet of essential amino acids could keep dementia at bay
- ScienceDaily
- 21/10/22 23:14
Protein intake is known to be vital for maintaining brain function in older individuals. Now, using a mouse model of Alzheimer's disease, researchers have shown that the intake of a specific set of amino acids can inhibit the death of brain cells, protect the connections between them, and reduce inflammation, preserving brain function. Their research suggests that this amino acid combination...

Mechanism behind ineffective psoriasis drugs identified
- ScienceDaily
- 21/10/22 23:14
Interleukin-12 -- a messenger molecule of immune cells -- was long considered to trigger the development of psoriasis. Now, researchers have shown that interleukin-12 does not actually cause the skin disease but protects against it. This also explains why common psoriasis drugs that block the messenger show insufficient treatment efficacy.
Controlling light with a material three atoms thick
Most of us control light all the time without even thinking about it, usually in mundane ways: we don a pair of sunglasses and put on sunscreen, and close—or open—our window blinds.
With more humpback whales in B.C. waters, entanglements are on the rise, too
A team of highly specialized professionals take on the task of disentangling whales — but rely on the eyes and ears of the community to find animals that have been caught up in fishing...
Record 21 humpback calves spotted in Salish Sea over feeding season as whale numbers rebound
A record number of humpback whale calves have been documented swimming off the coast of Washington State and British Columbia this summer and...
The climate project that changed how we understand extreme weather
When a handful of scientists tried to publish rapid research into the role of climate change in record rainfall that lashed Britain in 2015, they were told their high-speed approach was "not science".
Discovery of ancient Peruvian burial tombs sheds new light on Wari culture
A team of archeologists in northern Peru discovered the remains of 29 people, including three children, that could help experts rewrite the history of the pre-Incan Wari civilization, the lead researcher said on Friday.
Experiments confirm a quantum material's unique response to circularly polarized laser light
When the COVID-19 pandemic shut down experiments at the Department of Energy's SLAC National Accelerator Laboratory early last year, Shambhu Ghimire's research group was forced to find another way to study an intriguing research target: quantum materials known as topological insulators, or TIs, which conduct electric current on their surfaces but not through their interiors.
Chemists discover mechanism in controlled growth of tetrahedron-shaped nanoparticles
Nature clearly likes symmetry. Look at your own hands, for example. But sometimes nature produces asymmetric things, and the reasons aren't always clear.
A national network examining Earth's planetary limits
University of California San Diego Physics Professor Tom Murphy is among five authors of an essay, appearing in the November 2021 issue of the journal Energy Research & Social Science, that cautions current levels of worldwide economic growth, energy use and resource consumption will overshoot Earth's finite limits.
