On January 1, 1925, astronomer Edwin Hubble completely changed the way we see the universe and our place in it. The discovery came from looking through the world’s largest telescope at the time, located on a remote mountaintop in the Angeles National Forest. Not only was the world changing, but so was life for Hubble, … Read more
The Hubble Space Telescope is back in action, having returned to science operations, but now with only one working gyroscope. And to prove it still has what it takes, the venerable observatory snapped a stunning photo of the dusty spiral galaxy NGC 1546. There are about 50 million light years far away in the constellation … Read more

Paleontologists have discovered a new species of ancient crocodile-like reptile that once roamed the lands and waters of Brazil. The fossils, found at a fossiliferous locality called “Linha Várzea 2” in southern Brazil, have now been named Parvosuchus aurelioi, an ancient new species of small predatory reptile dating back to approximately 237 million years ago, … Read more
A recent study published in Experimental Brain Research has shed new light on how complete sleep deprivation affects the brain’s ability to process and integrate multiple stimuli presented in sequence. Researchers found that a full day without sleep significantly impairs attentional and temporal integration mechanisms. In other words, being without sleep for an entire day … Read more

Summary: Advances in organoids and embryonic models raise questions about human individuality. A new study argues that these patterns may reinforce, not weaken, the concept of human individuality when viewed through the frameworks of personality and feelings. The researchers point out that current technologies are far from achieving personality in embryo models or organoids. The … Read more
A special group of stars orbiting the violent center of the Milky Way could become “immortal” by constantly capturing and destroying dark matter particles in their cores, a new study suggests. Using computer simulations of stellar evolution, the researchers found that dark matter particles captured by the gravity of these stars can often collide and … Read more
MPC1 is expressed in the human hair follicle, and inhibition of MPC inhibits cell cycle progression and disrupts gene expression of the hair follicle signaling pathway. A) MPC1 and PDK immunoreactivity in human hair follicle. CTS-connective tissue sheath. DP–dermal papilla; DSC–skin wrap cup; GL–germinating layer; HS–hair shaft; IRS-internal root sheath; L-ORS – lower outer root … Read more
Geologists digging into the massive West Antarctic ice sheet have uncovered the remains of an ancient river system that once flowed for nearly a thousand miles. The discovery provides a glimpse into Earth’s history and hints at how extreme climate change could alter the planet, according to their findings, published June 5 in the journal … Read more
