From the surface, Chetumal Bay looks almost placid – just a wide sheet of water with no hint of drama underneath. But below that calm is Taam ja’, a massive underwater sinkhole, or “blue hole,” that’s turned into an unexpected mystery for scientists.

Helium-3 is usually talked about as a Moon resource – something future astronauts might mine from lunar dust to power fusion reactors or cool quantum machines. Its discovery beneath forests and wetlands in northern Minnesota has surprised many scientists.

Scientists in Sweden recovered RNA from an extinct, 130-year-old Tasmanian tiger, also known as a thylacine. They then traced which genes were active in its tissues.

A new global review argues that many “transition” projects touted by oil and gas companies, such as hydrogen hubs, biofuels, or carbon capture and storage, are doing more to lock in the fossil economy than to wind it down.

…Many of the passages are longer than 600 yards (550 meters) and tall enough for an adult to walk through without bending.

Neutron counts under the Chernobyl sarcophagus rose, but the best evidence says the spike came from shifting moisture inside the wrecked reactor, not an approaching chain reaction.

“We now have direct evidence that not only was the ice gone, but that plants and insects were living there,”...Near‑complete melting of Greenland’s ice over the next centuries to a few millennia would lead to some 23 feet of sea‑level rise.

Won't be long now.

This sort of time flip has been described as looking into a mirror and spotting your back instead of your face...By carefully adjusting electronic components on a strip of metal, they introduced a sudden jump that reversed the direction of incoming signals...The outcome was a time-reversed copy of the original wave, appearing just as predicted but never before seen with clarity...A wave that can jump to a new frequency and then rewind might open new possibilities for data transmission at different ranges of the spectrum. It could also reshape how certain sensors and imaging systems are designed.

Imagine spending hours on the couch, feeling good about the morning’s workout. You ran, you lifted, you stretched. You believe you’ve done enough to protect your health. But new research says that may not be true.

Great for environment but also bees are adorable
