Solar storm confirms Vikings settled in North America exactly 1,000 years ago
Analysis of wood from timber-framed buildings in Newfoundland shows Norse-built settlement 471 years before ColumbusLong before Columbus crossed the Atlantic, eight timber-framed buildings covered in sod stood on a terrace above a peat bog and stream at the northern tip of Canada’s island of Newfoundland, evidence that the Vikings had reached the New World first.But precisely when the Vikings...
Decarbonizing industries with connectivity and 5G
Around the world, citizens, governments, and corporations are mobilizing to reduce carbon emissions. The unprecedented and ongoing climate disasters have put the necessity to decarbonize into sharp relief. In 2021 alone these climate emergencies included a blistering “heat dome” of nearly 50 °C in the normally temperate Pacific Northwest of the United States and Canada, deadly and destructive...
Lead remediation efforts show promise for safe drinking water in New York city public schools
Since the water crisis in Flint, Michigan, many states have passed legislation requiring public schools to assess and treat lead in their drinking water. Two Princeton University researchers examined the efforts by New York City, the largest school district in the country, to determine the efficacy of its lead reduction strategies.
Cancer therapies and nuclear material detection get a boost from newly discovered protein
Lawrence Livermore National Laboratory (LLNL) and Penn State scientists have demonstrated how a protein can be recovered and purified for radioactive metals like actinium that could be beneficial for both next-generation drugs used in cancer therapies and the detection of nuclear activities.
Reducing carbon dioxide using a panchromatic osmium complex photosensitizer
Finding solutions for the current climate and energy crisis has become a common goal across the globe. And why look far when we have the perfect solution right around us? Taking a page out of nature's book, scientists have been trying to recreate the process of photosynthesis to combat climate change. Beyond helping plants prepare their food, photosynthesis also makes them one of the major carbon...
Tailoring affects people's perceptions of dates suggested by online dating apps
Users of online dating apps evaluate date-worthiness of recommended partners based on the tailoring process used by the app, according to new research led by Penn State. The team's results suggest that it matters whether the app uses an algorithm to suggest potential partners or uses the date preferences indicated by users.
Innovative models predict effects of climate change on nor'easters
Argonne-developed high-resolution models predict the effect of climate change on the extratropical storms that bear down on the Northeast in the winter.
NASA challenges K-12 students to design moon-digging robots
NASA seeks young engineers to help design a new robot concept for an excavation mission on the Moon. The Lunabotics Junior Contest is open to K-12 students in U.S. public and private schools, as well as home-schoolers.

Scientists have revealed how bacteria make tiny liquid droplets from proteins to help them survive harsh environments and thus reduce their chances of being killed by antibiotics.
A breakdown in communication: Mitochondria of diabetic patients can’t keep time
- ScienceDaily
- 21/10/20 21:04
Muscle cells in patients with type 2 diabetes have a disrupted biological clock. The new findings suggest that treatments for type 2 diabetes may be more or less effective depending on the time of day they are given.

Researchers describe the first crab from the Cretaceous dinosaur era preserved in amber. The study used micro CT to examine and describe Cretapsara athanata, the oldest modern-looking crab (approximately 100 million years old) and the most complete fossil crab ever discovered.
Rediscover trust in cybersecurity
The world has changed dramatically in a short amount of time—changing the world of work along with it. The new hybrid remote and in-office work world has ramifications for tech—specifically cybersecurity—and signals that it’s time to acknowledge just how intertwined humans and technology truly are.
Enabling a fast-paced, cloud-powered collaboration culture is critical to rapidly growing...
Remoteness does not enhance coral reef resilience, according to marine ecologists
There's a widespread hypothesis that links the resilience of coral reefs with their remoteness from human activities—the farther away they are from people, the more likely corals are to bounce back from disturbances.
Citizen scientists help assure quality of coastal biodiversity monitoring
In 2019, history student Rodrigo Gomes found out on social media about a call for volunteers to take part in a scientific project relating to the ocean and conducted by the Federal University of São Paulo's Institute of Marine Sciences (IMAR-UNIFESP) in Santos, on the coast of the state of São Paulo, Brazil. He signed up for the project, took workshops, and trained in the field. "I was very...
Changing ocean currents are driving extreme winter weather
Throughout Earth's oceans runs a conveyor belt of water. Its churning is powered by differences in the water's temperature and saltiness, and weather patterns around the world are regulated by its activity.
