There is an increasingly need to decarbonize air travel, but that doesn’t mean that we’ll be cutting the cord on it anytime soon.Air travel is imperative for global connectivity, with roughly 100,000 flights in transit every day carrying people and goods around the world. Aircrafts come with a lengthy list of qualifications, like the need to be lightweight, ...read more

Timor Island might not have been a stepping stone. Many archeologists have theorized that the island, served as a sort of way station for travelers en route to destinations further south and east, like Australia. The island lies southeast of Indonesia and about 450 miles from Australia’s northern coast. But the sheer number of artifacts — and the fact that many dated to the same time period about 45,000 years ago — instead indicates the island was targeted for colonization, according to a ...read more

There’s a reason why high achievers are commonly told to “shoot for the stars” — space travel is far from a simple task. While once an ambitious goal, limited to government entities that had the funding and technology to execute major launches, commercial launches are dominating outer space today, giving rise to a relatively new, rapidly growing industry. “I would say many of the trends we're seeing in the space industry, from increased satellites in orbit to decreasing payload sizes, ...read more

It’s a simple idea: Stop mowing your lawn in the month of May to let flowers in the lawn, such as dandelions and clover, grow and support bees and other pollinators.“No Mow May” was started in 2019 by Plantlife, a conservation charity based in the United Kingdom, in response to a well-documented loss of meadows and an alarming decline of native plants and animals there.

The question of whether some dinosaurs were covered with either scales or feathers has a new answer: both.Researchers examined the skin of the feathered dinosaur Psittacosaurus from the early Cretaceous period (135 million years to 120 million years ago) and found “zones” of reptile-style scales as well as “zones” where feathers were present, according to a study in Nature Communications. The early Cretaceous marks the period when some dinosaurs were evolving into birds. Rare Skin Sample ...read more

We’ve known for some time now that during sleep, the brain undergoes a memory spring cleaning of sorts, during which thoughts collected during that day are either converted into long-term memories or discarded.It makes sense that this brain cleanse would occur at night when the brain is idle, considering there’s no way that even the enormous human brain could possibly have enough room for everything that we take in on a given day.Until recently, researchers didn’t understand the mechanism ...read more

Have you ever had your dog get irritated red paws after running around in the grass outside, or has your cat recently developed a rash?

But like any medication, however, Ozempic and similar drugs — which use semaglutide as an active ingredient to mimic a naturally occurring hormone called GLP-1 — c ...read more
