Labs Can Now Grow Your Guts
23rd February 2017 | | Tech

When it comes to growing intestines, the first inch is the hardest—especially in a petri dish. Scientists at Cincinnati Children’s Hospital Medical Center have met that benchmark: they recently reported in Nature Medicine that they had grown a piece of gut—nerves, muscles and all—from a single line of human stem cells. In the future such tissue could be used for studying disease and more.

These Microscopic Bots Could Swim through the Bloodstream to Deliver Drugs
23rd February 2017 | | Tech

Microscopic machines that swim through the bloodstream to deliver drugs or perform minor surgeries have been a dream of scientists for decades. In the past 15 years researchers have created micro-engine variants that rely on chemical reactions, magnetism or vibration for thrust—but they often motor around erratically. The main challenge is guiding them to where they are needed

New class of drugs to combat aging diseases discovered
23rd February 2017 | | Tech

New details of the aging process have been uncovered by a research team. They discovered an altered balance between certain signaling molecules in the smooth muscle cells of blood vessels and the heart. The team also discovered a new class of drugs that combats an important part of the aging process.

New method uses heat flow to levitate variety of objects
22nd February 2017 | Tech

Although scientists have been able to levitate specific types of material, a pair of UChicago undergraduate physics students helped take the science to a new level.

Third-year Frankie Fung and fourth-year Mykhaylo Usatyuk led a team of UChicago researchers who demonstrated how to levitate a variety of objects—ceramic and polyethylene spheres, glass bubbles, ice particles, lint strands and thistle seeds—between a warm plate and a cold plate in a vacuum chamber.
