Researchers in 2024 may have found evidence of ancient life on Mars through NASA's Perseverance rover, which discovered a rock with white spots that could be linked to microbial life.
NASA’s Perseverance rover discovered leopard spot–like features in this Martian rock (closeup image shown). On Earth, similar structures are associated with microbial life.
Superconductivity may be achieved without frigid conditions, with scientists using a laser to create magnetic fields in a copper and oxygen compound.
Researchers propose that Egypt's first pyramid was built using a water-powered elevator nearly 4,700 years ago, based on a computer model of the Step Pyramid of Djoser.
A midsize black hole may have been spotted in our galaxy, with astronomers suggesting it has a mass of at least 8,200 times that of the sun.
Alzheimer's disease may be transmissible in extremely rare cases, with researchers suggesting that contaminated growth hormone injections could have caused the disease in five patients.
High levels of the protein amyloid-beta — a hallmark of Alzheimer’s disease — appear orange and purple in this brain scan of a man with the disease. Childhood exposure to the protein via contaminated growth hormone injections may have led the man to develop Alzheimer’s later in life.
Dark energy may be more complex than previously thought, with new observations suggesting that its density and pressure may change over time, rewriting our understanding of the universe's history.
