Scientists detect signatures of life remotely
on June 18, 2021 at 5:39 pm
It could be a milestone on the path to detecting life on other planets: Scientists detect a key molecular property of all living organisms from a helicopter flying several kilometers above ground. The measurement technology could also open up […]
Most cancer cells grown in a dish have little in common with cancer cells in people,...
on June 18, 2021 at 1:17 pm
In a bid to find or refine laboratory research models for cancer that better compare with what happens in living people, scientists report they have developed a new computer-based technique showing that human cancer cells grown in culture dishes are […]
Unraveling the origin of Alzheimer's disease
on June 17, 2021 at 6:36 pm
Researchers studying prions -- misfolded proteins that cause lethal incurable diseases -- have identified the surface features of human prions responsible for their replication in the brain.
Physicists bring human-scale object to near standstill, reaching a quantum state
on June 17, 2021 at 6:36 pm
In the last few decades, physicists have found ways to super-cool objects so that their atoms are at a near standstill, wrestling small objects such as clouds of millions of atoms, or nanogram-scale objects, into such pure quantum states. Now […]
New method could reveal what genes we might have inherited from Neanderthals
on June 17, 2021 at 3:55 pm
Using neural networks, researchers have developed a new method to search the human genome for beneficial mutations from Neanderthals and other archaic humans. These humans are known to have interbred with modern humans, but the overall fate of the […]
We cannot cheat aging and death, study indicates
on June 16, 2021 at 1:41 pm
Philosophers, artists and scientists -- and probably all the rest of us -- have long obsessed over the key to human immortality. We all, no matter our income, culture or religion are bound to die. Even if we escape mortal diseases or accidents, we […]
New discovery shows human cells can write RNA sequences into DNA
on June 11, 2021 at 9:40 pm
In a discovery that challenges long-held dogma in biology, researchers show that mammalian cells can convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells.
Study finds brain areas involved in seeking information about bad possibilities
on June 11, 2021 at 3:08 pm
Researchers have identified the brain regions involved in choosing whether to find out if a bad event is about to happen.
African great apes to suffer massive range loss in next 30 years
on June 7, 2021 at 8:10 pm
A new study predicts massive range declines of Africa's great apes -- gorillas, chimpanzees and bonobos -- due to the impacts of climate change, land-use changes and human population growth.
