A new 3D printer uses light to transform gooey liquids into complex solid objects in only a matter of minutes.
Nicknamed the “replicator” by the inventors — after the Star Trek device that can materialize any object on demand — the 3D printer can create objects that are smoother, more flexible and more complex than what is possible with traditional 3D printers. It can also encase an already existing object with new materials — for instance, adding a handle to a metal screwdriver shaft — which current printers struggle to do.
Greenland is melting faster than scientists previously thought—and will likely lead to faster sea level rise—thanks to the continued, accelerating warming of the Earth’s atmosphere, a new study has found.
Study finds an archaic hominin had modern dental growth
A relative of modern humans that lived at least 104,000 years ago in northern China showed evidence of dental growth and development very similar to that of people today, a new study found.
People with Huntington’s disease suffer from jerky body movements and decreasing mental abilities. The condition usually leads to death 15–20 years after diagnosis. The cause of the disease is a region in the Huntingtin gene that is longer than in healthy people. The mutation causes the destruction of brain cells.
In a new study, researchers at the Biodesign Institute explore a safe and simple treatment for one of the most devastating and perplexing afflictions: Alzheimer’s disease (AD).
Feeling alone linked to psychological and physical ills, but wisdom may be a protective factor
In recent years, public health officials have warned about a rising epidemic of loneliness, with rates of loneliness reportedly doubling over the past 50 years. In a new study, researchers at University of California San Diego School of Medicine put a specific, concerning and surprising face to the issue.
Schizophrenia is among the most difficult mental illnesses to treat, in part because it is characterized by a wide range of dysfunction, from hallucinations and mood disorders to cognitive impairment, especially verbal and working memory, which can be explained in part by abnormalities in early auditory information processing.
