Tesla has revealed some of its humanoid robot technology through filings for several new patents related to its Optimus robot program.

A few months ago, Tesla unveiled “Optimus Gen 2”, a new generation of its humanoid robot that should be able to take over repetitive tasks from humans.

The new prototype showed a lot of improvements compared to previously underwhelming versions of the robot, and it gave some credibility to the project.

Consistently exercising 2–3 times a week over the long term is linked to a lower current risk of insomnia as well as the ability to clock up the recommended 6–9 hours of shut-eye every night, suggests an international 10-year study published in the open access journal BMJ Open.

Regular exercise is associated with better overall health, and several studies have suggested that physical activity promotes better quality sleep and may improve symptoms of chronic insomnia, note the researchers.

But it’s not entirely clear how much gender, age, weight (BMI), overall fitness, general health, and exercise type contribute to this association, they add.

For as long as superheroes have been imagined, there’s been a superhero who can regrow limbs. Other animals (like salamanders and sharks) do it, why couldn’t we? Scientists have also tackled this question because, obviously, humans don’t naturally regrow limbs. But before we move on to regrowing limbs ourselves, we need to understand how other species do it.

In a new study, researchers mapped the proteins that kick off limb creation in mice and chicks, finding that a cocktail of just three proteins performs the initial magic.

“People in the field have known a lot of the proteins critical for limb formation, but we found that there are proteins we missed,” said study co-first author ChangHee Lee, research fellow in genetics in the lab of Cliff Tabin at Harvard Medical School.

Long suspected to exist, cancer stem cells were discovered in solid tumors about 20 years ago. Is this the long-sought root cause of cancer? Thousands of scientists now believe so. Then why haven’t you heard about this from your oncologist? We delve into the debate on CSCs, and explore which foods and food supplements are most effective in the lab at killing or blocking cancer stem cells.
