A fully electric tractor that recharges from its own solar roof goes on sale in North America, runs about five hours per charge and could save small farms around $15,000 over five years
Anyone who has spent a morning next to a diesel tractor knows the routine. The…..
China has tested a flying wing built to carry more than 800 passengers with an 85-meter span wider than an A380, and the real obstacle is not the aircraft but the airports that would have to park it
Chinese researchers have tested a small wind-tunnel model representing an aircraft concept that could carry…..
Germany built a “flying train” above a crowded river valley in 1901 because there was barely any room left on the ground, and 125 years later the eight-mile suspended railway still carries more than 80,000 passengers every day
Germany’s “flying train” is not a futuristic proposal waiting for approval. Wuppertal’s Schwebebahn opened to…..
One unpermitted truck load hit six Oklahoma bridges in a single trip, and the mistake cost nearly half a million dollars
An unpermitted truck hit six Oklahoma bridges in one trip, costing $491,700 and exposing gaps in route planning.
A 46-foot robot boat found a distress beacon off Plymouth, and its steady hull may matter more to navies than hydrogen
Built to test hydrogen power, ACUA’s Pioneer vessel runs on diesel instead, since hydrogen lasts 18 days at sea versus 50 on diesel.
Houston built a 26-lane freeway to beat traffic, but the cars came back and exposed the trap behind wider roads
Houston spent nearly $3 billion widening a freeway to 26 lanes, but induced demand brought traffic back within years.

The world’s southernmost wind farm uses just three turbines to help power U.S. and New Zealand research bases in Antarctica, cutting diesel consumption by about 122,000 gallons a year and preventing an estimated 1,242 metric tons of CO₂ emissions despite operating in one of Earth’s harshest environments
On a frozen ridge of Ross Island, three wind turbines turn above American McMurdo Station and New…..
Nearly 5,000 solar panels were installed on a Swiss dam 8,200 feet above sea level, and despite deep snow and freezing temperatures the Alpine plant produced 3.8 times more winter electricity per unit of capacity than a lowland installation during its first measured year

Janelia scientists spent 18 years mapping every neuron in a male fruit fly, 166,700 cells and 125 million connections, and days after the map came out programmers had it playing Doom
In 2008, Gerry Rubin’s lab in Ashburn, Virginia, decided to map every neuron in a…..
Scientists on Trinidad and Tobago’s first locally led deep-sea expedition followed 219 bubble streams to 25 cold seeps and found at least 20 possible new species, including an octopus first seen in 2014
Far below Trinidad and Tobago’s familiar coastal waters, scientists have documented 25 cold-seep ecosystems and…..
Two Oregon State studies of 1,512 adults found social media support eased loneliness far less than real-life ties, and checking apps within 30 minutes of waking was tied to twice the odds of depression
A phone full of messages can make staying connected feel effortless, but does that connection…..
Divers off British Columbia found two sea spider species new to science, the first described in the Salish Sea in almost a century, and one has red eyes and legs so spiny its name means hairy feet
Two newly described sea spider species are bringing an overlooked corner of coastal wildlife into…..
NOAA scientists studying sponges collected in Alaska trawl surveys as early as 1997 identified nine deep-sea sponges new to science, including a red one so unusual that it needed a brand-new genus
Scientists have identified nine previously undescribed sponge species in the Gulf of Alaska and the…..
A study that tracked 1,967 people in Singapore with smart rings found university students averaging 20 moved 100 minutes less per day than adults in their 70s and spent over 10.5 hours a day sitting
College life can feel like a constant rush between lectures, assignments, and late nights. But…..
