Embryonic microRNA fuels heart cell regeneration, researchers show

Posted by in category: biotech/medical

By adulthood, the heart is no longer able to replenish injured or diseased cells. As a result, heart disease or an event like a heart attack can be disastrous, leading to massive cell death and permanent declines in function. A new study by scientists at the Lewis Katz School of Medicine at Temple University (LKSOM), however, shows that it may be possible to reverse this damage and restore heart function, even after a severe heart attack.

The study, published June 21 in the print edition of the journal Circulation Research, is the first to show that a very small RNA molecule known as miR-294, when introduced into , can reactivate cell proliferation and improve heart function in mice that have suffered the equivalent of a in humans.

“In previous work, we discovered that miR-294 actively regulates the in the developing heart,” said Mohsin Khan, Ph.D., Assistant Professor of Physiology at the Center for Metabolic Disease Research at LKSOM. “But shortly after birth miR-294 is no longer expressed.”

Scientists map huge undersea fresh-water aquifer off US Northeast

Posted by in category: innovation

In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles. The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out.

The researchers employed innovative measurements of electromagnetic waves to map the , which remained invisible to other technologies. “We knew there was fresh water down there in isolated places, but we did not know the extent or geometry,” said lead author Chloe Gustafson, a Ph.D. candidate at Columbia University’s Lamont-Doherty Earth Observatory. “It could turn out to be an important resource in other parts of the world.” The study appears this week in the journal Scientific Reports.

The first hints of the aquifer came in the 1970s, when companies drilled off the coastline for oil, but sometimes instead hit fresh water. Drill holes are just pinpricks in the seafloor, and scientists debated whether the water deposits were just isolated pockets or something bigger. Starting about 20 years ago, study coauthor Kerry Key, now a Lamont-Doherty geophysicist, helped oil companies develop techniques to use electromagnetic imaging of the sub-seafloor to look for oil. More recently, Key decided to see if some form of the technology could also be used also to find fresh-water deposits. In 2015, he and Rob L. Evans of Woods Hole Oceanographic Institution spent 10 days on the Lamont-Doherty research vessel Marcus G. Langseth making measurements off southern New Jersey and the Massachusetts island of Martha’s Vineyard, where scattered drill holes had hit fresh-water-rich sediments.

McDonald’s Tests Robot Fryers and Voice-Activated Drive-Throughs

Posted by in categories: food, robotics/AI

McDonald’s Corp. is designing voice-activated drive-throughs and robotic deep-fryers as the burger giant works to streamline its menu and operations to speed up service.

The company is testing voice-recognition software at a drive-through in suburban Chicago. Inside the restaurant, a robot also tosses chicken, fish and fries into vats of oil. Both technologies are meant to shorten customer wait times that executives acknowledge have grown in recent years. McDonald’s also has stopped serving some burgers and given franchisees…

Gensight Biologics Releases Data, CFO Responds to LEAF Inquiry

Posted by in categories: biotech/medical, genetics, life extension

Gensight Biologics, a company researching – among other things – the movement of mitochondrial genetic information to the nucleus to treat hereditary genetic diseases (a strategy that could also have an impact on aging according to the SENS Research Foundation), has recently released data for its latest trial of GS010, a therapy against the blindness-causing genetic disease LHON.
