The new data set shows how radio waves lose strength inside buildings at the 3. 5 GHz band, a key frequency for next‑generation mobile networks. Researchers set up three different rooms – a living space, an office area and a warehouse – each with its own layout and wall materials. They placed
Melasma shows up as brown patches on the face and can make people feel self‑conscious. Researchers are looking beyond skin care to explain why it happens. They use the idea of an “exposome, ” which means all the things a person is exposed to over life. These exposures can be inside the body
When people step into a garden, they often see only flowers and vegetables. Yet behind every sprout lies a story of discovery that stretches back to ancient times. Early humans experimented with plants, learning which could feed them or heal wounds. This trial‑and‑error period was not painless; man
Scientists used a single metal‑organic framework, PCN‑608, to separate its two main variables: the crystal’s shape and what sits inside its pores. They grew three kinds of crystals – tiny disks, flat sheets, and interlocked sheets – to see how shape changes the path a gas takes. They also adde
Lake Tahoe draws crowds every summer, but the surge in visitors is testing the lake’s delicate balance. More people than ever want to explore its trails, beaches, and clear waters, yet the way they get there is doing real damage. Packed roads and illegal parking spots are making it harder for wildli
A high school in Waukegan made a smart move by putting 932 solar panels on its big roof. The school used to pay a lot for electricity—now it saves over $94, 000 every year. That money now helps teens from families with fewer resources go to college instead of going toward power bills. The panels do
The idea of cutting energy costs by a huge amount might sound like science‑fiction, but it is really about getting smarter with what we already have. Instead of building new power plants or inventing exotic fuels, the trick is to use less electricity in the first place. When people talk about
Companies in China’s most polluting industries often get caught between two kinds of government pressure. One kind, called environmental subsidies, actually seems to push some firms toward lying about how green they are. It sounds backwards, but getting cash for being green can make managers focus o
Scientists recently found traces of PFOS, a long-lasting chemical, inside honey and the bees that make it. These substances stick around in nature for years, building up in the environment and even inside living things. For bees, even small doses can mess with their growth. Young bees exposed to PFO
Raccoons trash pandas are more than just pests rummaging through bins. Scientists at the University of British Columbia tested 20 captive raccoons with a clear box full of obstacles like latches and dials hiding a marshmallow prize. The team noticed something unexpected the raccoons didn’t just grab
