Why Are Americans Still—Still!—Wearing Cloth Masks?
Every time I leave my apartment, I grab a mask from the stack by the door. After all these months of pandemic life, I’ve amassed a pretty big collection: Some are embroidered, while others bear the faded logos of the New York Public Library or the TV show Nailed It . What all of them have in common is that they’re made of cloth. At this point, cloth masks are so ubiquitous in the United States th

Fact Check: Is Facebook Down Because 1.5 Billion Users’ Data Was Stolen?
Unless you’ve been using the internet under a rock, you’ve probably noticed that Facebook, along with several of its other services, is down. Like, really down .

Work on Earth’s Climate and Other Complex Systems Earns Nobel Prize in Physics
Physicists traditionally deal with simple systems — a single atom, a gas in a box — for which the governing laws are clear and exact answers can be calculated.

Simple method for converting carbon dioxide into useful compounds

Exposure to deadly urban heat worldwide has tripled in recent decades, says study
A new study of more than 13,000 cities worldwide has found that the number of person-days in which inhabitants are exposed to extreme combinations of heat and humidity has tripled since the 1980s. The authors say the trend, which now affects nearly a quarter of the world's population, is the combined result of both rising temperatures and booming urban population growth.

Spider silk's supposed 'healing properties' might have no basis in science
As far back as ancient Rome, spider silk has been used as a remedy to treat everything from skin lesions to warts. In the past, doctors have covered open wounds in cobwebs or advised patients to place cocoons on infected teeth. In modern times, however, the literature contains conflicting reports of whether or not spider silk has antimicrobial properties. In the journal iScience on October 5th, re

Socialt samspel viktigt när du lånar ut din soffa
Vill du dela bil med dina grannar, eller ha en främling sovande i gästrummet? Om svaret är ja – vem har ansvaret om bilen går sönder och vad säger din familj om att vilt främmande människor kommer och går? Delningsekonomi är egentligen inget nytt, människor har i alla tider bytt varor och tjänster med varandra. Det nya ligger i de tekniska plattformar som gör affärsmodellerna möjliga. Via Airbnb:

Moonshot Project Aims to Understand and Beat Cancer Using Protein Maps
Understanding cancer is like assembling IKEA furniture. Hear me out. Both start with individual pieces that make up the final product. For a cabinet, it’s a list of labeled precut plywood. For cancer, it’s a ledger of genes that—through the Human Genome Project and subsequent studies—we know are somehow involved in cells mutating, spreading, and eventually killing their host. Yet without instruct

Metallic complexes made from cyclic molecules
In polymetallic complexes, two or more metal atoms combine with organic molecules into larger, complicated molecular structures. Such complexes are used in the development of e.g. new catalysts, molecular magnets and sensors. In the past, polymetallic complexes were often synthesized by the trial-and-error method of mixing metal ions with organic ligands, resulting in unpredictable compounds. The

Cellular mechanism that allows stem cells to maintain their state
Embryonic stem cells can give rise to every cell type in the body. A team of researchers from Sweden, in collaboration with groups in Switzerland and Canada, has now identified a cellular mechanism that is important for the ability of these cells to maintain their state as stem cells. The findings, published in the journal Cell Reports, add to the knowledge needed to bring forward the field of reg

Attribution science: Linking climate change to extreme weather
At the end of August, category four Hurricane Ida ravaged Louisiana and caused enormous damage in the Northeast due to flooding. Many homes in both regions were destroyed and prolonged power outages occurred. As Ida moved north, it spawned tornadoes, record rainfall, extensive flooding, and resulted in 82 deaths. Is it possible to determine how much climate change influenced an extreme event like

Precision tools for farming mussels and oysters more sustainably
Aquaculture is the fastest growing animal food producing sector in the world. But in the past, it has lagged behind other food sectors in adopting more efficient information systems. Now, driven by the vision of sustainable development, the aquaculture sector is rapidly introducing technologies that will make greener, more efficient fish farm management a reality.

New data shows that homelessness is a women's rights issue
Visible homelessness during the COVID-19 pandemic has highlighted the housing crisis across Canada. For women, girls and gender-diverse people, homelessness is often hidden, meaning that they are more likely to avoid shelters, couch surf or remain in abusive relationships than end up on the streets. Because of this, we know less about their experiences.

It will soon be possible to make satellite phone calls with your regular phone
Not all who wander are lost—but sometimes their cell phone reception is. That might change soon if a plan to project basic cell phone coverage to all parts of the globe comes to fruition. Lynk has already proven it can use a typical smartphone to bound a standard SMS text message off a low-earth-orbiting satellite, and they don't plan to stop there.
