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.
