Exercise is medicine for cancer and every dose counts - even in late stages of the disease

Even a single bout of exercise can produce anti-cancer proteins called myokines, which can significantly suppress tumour growth.

Scientists have found two “water worlds” that are unlike anything seen in our solar system.

The planets are almost entirely made up largely of water, marking the first time that such worlds have ever been confidently identified by scientists.

Previously, the researchers were thought to be far more standard planets – but they are actually far more pioneering than we realised, scientists say.

“We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that’s why we called them super-Earths,” said Björn Benneke, one of the scientists on the new research and professor of astrophysics at the University of Montreal.

“However, we have now shown that these two planets, Kepler-138c and d, are quite different in nature: a big fraction of their entire volume is likely composed of water. It is the first time we observe planets that can be confidently identified as water worlds, a type of planet that was theorized by astronomers to exist for a long time.”

Scientists have not directly detected the water, and that remains difficult at such a long distance. But investigation showed that up to half of the planet should be made up of something lighter than rock and heavier than hydrogen – and the most likely candidate for that material is water.

The two planets are in orbit the star Kepler-138, which is 218 light years and situated in the Lyra constellation. They have volumes three times that of Earth, and masses twice as big – but are much less dense than our own planet...............

This could just as easily have gone in the TIL thread, but here is better. We all know about the double slit experiment, right? Photons act as waves when unobserved and act as particles when observed and we can't figure out why. Well, they did an experiment where the detector did not activate until AFTER the photons passed thru the slits. The photons passed thru the slits as waves but as soon as the detector activated, the photons WENT BACK IN TIME and changed to particles.

This is not the video, but in another one Tyson put the odds at 50/50.

He said we are either the origional "real" universe that has not yet reached the ability for a fully functional simulation, or we are the newest/last simulation that has not yet reached the ability to create our own child universe.

All the ones in the middle would be out, because we would have to know how to create full worlds already to be one of those.

NASA Tests Upgraded Megarocket Engine Ahead of Future Moon Missions

The crewed Artemis 5 mission to the Moon won’t happen until 2028 at the earliest, but the mission and those that follow will benefit from upgraded RS-25 engines, which NASA will use to power future iterations of its gigantic Space Launch System rocket.

I was at Stennis about 15 years ago for a two-week course training and got to watch an engine test like this. They are quite memorable to witness in person.

Yeah my sister was working there back then and said the same thing.

Reported sleep duration reveals segmentation of the adult life-course into three phases - Nature Communications

Sleep varies within and between individuals. Here, using self-reported sleep duration from a large sample of participants across 63 countries, the authors show three phases in the adult human life-course, consistent across culture, gender, education and other demographics.
