Scientists have analyzed the diets of ancient Americans by studying the isotopes in their bones. This research has revealed that early Americans did not eat a balanced diet with plenty of fruits, vegetables, and whole grains like modern children are told to do.
In fact, people living during the Clovis period (around 13,000 years ago) likely relied heavily on hunting for food, which would have provided them with high amounts of protein but also limited the variety of their diet. This contrasts with the usual advice to eat more leafy greens and fruits.
Recent advancements in neuroscience and technology are helping scientists develop new treatments for paralysis. For example, implanted electrodes can allow paralyzed people to walk again by stimulating parts of the brain that control movement. This technology has shown promise in clinical trials and could potentially improve the lives of millions of people worldwide.
SpaceX’s dominance in space launches is also being questioned. The company’s CEO, Elon Musk, has sparked controversy by criticizing NASA’s heavy-lifting rocket program. Some are wondering whether Musk’s actions will have any impact on the future of space exploration.
In other news, ideas for making money in orbit that were once considered outlandish are now gaining traction. Asteroid mining and orbital manufacturing are just a few examples of the many opportunities being explored.
Finally, the Royal Society has been criticized by Elon Musk over membership fees. However, the dispute led to a high-profile resignation from one of its members. On a related note, deforestation is having devastating effects on Brazilian farmers, who are losing millions due to the lack of trees. The absence of trees makes it difficult for the land to retain moisture, leading to hotter and drier conditions.
Robots are becoming increasingly sophisticated thanks to advancements in artificial intelligence (AI). These robots can learn new actions faster than humans and may soon be used in settings such as car factories and care homes.
