A tiny piece of 3D-printed tech could foreshadow the future of medicine.
A team from MIT, Draper, and Brigham and Women’s Hospital has created a 3D-printed smart pill that can release medications in the stomach and monitor temperature for up to a month at a time — and they believe they’ve only scratched the surface of its capabilities.
The seeds of Alzheimer’s disease can be transmitted through medical procedures, scientists have found, leading experts to call for the monitoring of blood transfusions from the elderly and those with a family history of dementia.
In 2015, researchers at University College London discovered that people who developed Creutzfeldt-Jakob disease (CJD) following treatments with human growth hormone also showed signs of Alzheimer’s in their brains after death.
The scientists tracked down vials of the same hormone and found that it did indeed contain misfolded amyloid-beta proteins, capable of setting off the deadly chain reaction which can lead to dementia.

Earlier today, Virgin Galactic sent its SpaceShipTwo commercial aircraft into space, a historic first for the private company. But at a maximum altitude of 51.4 miles (82.68 kilometers), the spaceplane fell 10.6 miles (17.32 kilometers) short of the Karman line—the internationally recognized boundary separating the atmosphere from space. Prompting the inevitable question: What the hell is space, anyway?
Before we nitpick Virgin Galactic’s achievement, let’s give credit where it’s due.
A disease-carrying, newly invasive tick to the United States, the Asian longhorned tick, is poised to spread across much of North America, suggests a new study published Thursday in the Journal of Medical Entomology. According to the study, the tick might be able to live anywhere from Southeastern Canada to most of the eastern half of the U.S. and even parts of the West Coast.
The Asian longhorned tick, or Haemaphysalis longicornis, made an unwelcome splash last year, when researchers and health officials discovered it on a pet sheep in New Jersey. Any hopes that the discovery was an isolated incident faded away this year, with sightings of the tick popping up again in New Jersey and eight other states this past spring and summer (Arkansas, Connecticut, Maryland, New York, North Carolina, Pennsylvania, Virginia, and West Virginia). Since 2017, the tick has been found on pets, farm animals, and at least two people in the U.S., and it’s possible that it might have made its way here at least as early as 2010.
For decades after the discovery of DNA, researchers mostly thought of genetics in terms of genes, the pieces or sequences of DNA that encode instructions for building proteins in cells. Then scientists discovered that genes make up just 2 percent of our DNA and that most genetic complexity stems from the vast non-gene code, which influences when genes are turned on or off. Further, half of that non-gene code was found to come from insertions of viral DNA. Consequently, say the authors, genetic variation, and the potential for disease-causing mistakes, occurs in transposons as well as in genes.
New laboratory techniques can identify which of our genes are influenced by DNA snippets that are left behind in our genetic code by viruses, a new study finds.
The latest test flight by Sir Richard Branson’s Virgin Galactic successfully rocketed to the edge of space and back.
The firm’s SpaceShipTwo passenger rocket ship reached a height of 82.7km, beyond the altitude at which US agencies have awarded astronaut wings.
It marked the plane’s fourth test flight and followed earlier setbacks in the firm’s space programme.
