Our ultimate goal is to improve regeneration of functional skin—and maybe other organs with the a similar endogenous mechanism.

University of Manchester scientists have cast new light on how our skin repairs itself, bringing the possibility of regeneration of the organ a step closer.

The study team, funded by the Medical Research Council and Helmut Horten Foundation, showed the activation of specific parts of the DNA leading to better division of human skin cells. The study is published in Nucleic Acid Research.

This 32000-year-old plant was long gone until scientists found its incredibly preserved seeds in Siberia and brought it back to life!

Pepper update:

Italian researchers have programmed a humanoid robot named Pepper, made by SoftBank Robotics in Japan, to “thinks out loud” so that users can hear its thought process. Hearing a robot voice its decision-making process increases the transparency and trust between humans and machines.

Arianna Pipitone and Antonio Chella at the University of Palermo, Italy, built an ‘inner speech model’ based on a cognitive architecture that allowed the robot to speak aloud its inner decision-making process, just like humans when faced with a challenge or a dilemma. With the inner speech, users can hear its thought process and better understand the robot’s motivations and decisions.

NASA’s Ingenuity Mars helicopter ‘went big’ with its second flight, reaching new milestones with a higher altitude, flying to the side and grabbing another black-and-white photo of its shadow on the ground below.

The US space agency said it climbed up to 16ft above the surface, hovered, tilted slightly and then moved sideways 7ft. When in position it hovered again to take a series of colour photos before landing.

While leaded gasoline was fully phased out in 1996 with the passage of the Clean Air Act, it still fuels a fleet of 170000 piston-engine airplanes and helicopters. Leaded aviation fuel, or avgas, now makes up “the largest remaining aggregate source of lead emissions to air in the U.S.,” according to the Environmental Protection Agency.

Meanwhile residents continue to live with the air quality that comes with living near an airport where small planes burning leaded fuel fly in and out, said Alarcon, who is also a volunteer organizer with the nonprofit tenant advocacy group Vecinos Activos. It’s also unclear to air quality experts and residents what is arguably safe.

“There is no bright line that says ‘Above this concentration lead is safe and below this concentration’ that it is not. You’d have to make a policy decision,” said Jay Turner, an engineering education professor at Washington University in St. Louis and member of the EPA’s Science Advisory Board. “We’re really careful to come back to this point that just because public areas might meet the EPA standard [for lead] doesn’t mean zero risk or zero concern.”

DARPA announced it has increased Lockheed Martin’s contract for satellite integration work for the Blackjack program by $27.3 million.

WASHINGTON — The Defense Advanced Research Projects Agency increased Lockheed Martin’s contract for satellite integration work for the Blackjack program by $27.3 million, the agency announced April 22.

DARPA a year ago selected Lockheed Martin as the satellite integrator for Blackjack, a project to demonstrate a network of small satellites in low Earth orbit for military communications, missile warning and navigation.

A remote island could host Elon Musk’s new Space X project — but its residents are not impressed.

They require less maintenance, and less pollution. Imagine if you used them as a battery backup during an emergency.

School board seals deal to bring 300 electric school buses to Montgomery County. The buses will recharge at night and run during the day. During the hot summers, the buses and charging stations can help store needed energy for local businesses.
