Found in a Spanish landfill, the fossils of the extinct species Pierolapithecus catalaunicus may reveal important clues about our origins.
After birth, the human heart loses its regenerative capacity almost completely. Damage to the heart muscle—for example, due to a heart attack—therefore usually leads to a permanent loss of function in adults. Scientists from the Max Planck Institute for Heart and Lung Research have now shown for the first time in mice that a change in the energy metabolism of heart muscle cells enables heart regeneration.
In the animals, heart function could thus be restored to a large extent after a heart attack. The study, published in the journal Nature, is groundbreaking and could enable completely new therapeutic approaches.
The loss of regenerative capacity in adults hearts is due, among other things, to the loss of the ability of heart muscle cells to divide after birth. This is accompanied by a fundamental change in the energy metabolism of the heart cells: Instead of obtaining energy from sugars, which is known as glycolysis, the heart muscle cells now obtain their energy largely from fats. This form of energy production is known as fatty acid oxidation.
The company has engineered an all-electric vertical take-off and landing jet, designed to offer leading capacity, low noise, and high performance with zero operating emissions, to the note of ten million dollars.
A German electric aviation company, Lilium, is preparing to make a bold entry into the United States market with its Electric Vertical Takeoff and Landing (eVTOL) aircraft. The company announced its partnership with Texas-based full-service air brokerage and management company, EMCJET, to tap into the private jet market, in a statement.

Little is as important for the future of the world, and our own lives, as how this history continues.
Geoscientists discovered a continent that had been hiding in plain sight for almost 375 years.
Historically, there’s been speculation about whether a continent known as Zealandia or Te Riu-a-Māui in the Māori language exists.
According to TN News, Zealandiais 1.89 million square miles in size. It was part of a supercontinent called Gondwana, which included most of Western Antarctica and Eastern Australia, over 500 million years ago.
Researchers have predicted—and confirmed—a secondary pattern on the ocellated lizard’s scales that is too subtle for our eyes to see.
Now Edelbroek is CEO of SpaceBorn United, a biotech startup seeking to pioneer the study of human reproduction away from Earth. Next year, he plans to send a mini lab on a rocket into low Earth orbit, where in vitro fertilization, or IVF, will take place. If it succeeds, Edelbroek hopes his work could pave the way for future space settlements.
“Humanity needs a backup plan,” he says. “If you want to be a sustainable species, you want to be a multiplanetary species.”
Beyond future space colonies, there is also a more pressing need to understand the effects of space on the human reproductive system. No one has ever become pregnant in space—yet. But with the rise of space tourism, it’s likely that it will eventually happen one day. Edelbroek thinks we should be prepared.
