Scientists Get Their First Glimpse At How New Memories Are Born

By 2020, there will be enough renewable energy to supply CHN, IND, and BRA combined.

Paris-based International Energy Agency (IEA) has predicted that by 2020, 26% of the world’s energy will come from renewable sources (solar, wind, hydro). The agency adds that the amount will be higher than the combined energy demands of country’s like China, India, and Brazil. The prediction was based on the assumption that in the next five years, 700 gigawatts will be added to the world’s current renewable energy capacity.

How Do You Stay Fit on a Mission to Mars?

This mini exercise device could be the key!

Onboard the International Space Station, astronauts need to work out to maintain their bone density and muscle mass, usually exercising 2 hours every single day. Throughout the week, they exercise on three different pieces of equipment–a bike, a treadmill and the Advanced Restive Exercise Device (ARED).

All these devices are needed to keep an astronaut healthy.

However, deep-space vehicles like our Orion Spacecraft aren’t as roomy as station, so everything — including exercise equipment — needs to be downsized. The Miniature Exercise Device (MED-2) is getting us one step closer to being able to keep astronauts’ bodies healthy on long journeys to the moon, Mars and beyond.

MED-2 is a compact, all-in-one exercise device that we developed and will be launching to the space station Tuesday, March 22. Onboard the station, we’ll see how MED-2 will perform in microgravity and how it will need to be further adapted for our Journey to Mars. However, it’s already pretty well equipped for deep space missions.

So what makes MED-2 so great for deep space travel and our Journey to Mars?

1. It is an all-in-one exercise device, meaning it can do both aerobic and resistive workouts. When we go to Mars, the less equipment we need, the better.

2. It’s incredibly light. The MED-2 weighs only 65 pounds, and every pound counts during space missions.

3. It has 5 - 350 pounds of resistance, despite weighing only 65 pounds. Astronauts don’t all lift the same amount, making the flexibility in MED-2’s “weights” essential.

4. It’s tiny. (Hence its name Miniature Exercise Device.) Not only is MED-2 incredibly light, but it also won’t take up a lot of space on any craft.

5. It powers itself. During an aerobic workout, the device charges, and then that power is used to run the resistive exercises. When traveling to space, it’s good when nothing goes to waste, and now astronauts’ workouts will help power the Journey to Mars.

MED-2 is only one of many devices and experiments flying on Orbital ATK’s Cygnus spacecraft. To find out more about the science on the space station, follow @ISS_Research and @Space_Station on Twitter.

British astronaut Tim Peake made this timelapse of lightning storms from the International Space Station. He says it was recorded as he flew from North Africa over Turkey towards Russia.

Patricia Cowings (b. 1948) is an aerospace psychophysiologist, and the first African American woman trained as an astronaut by NASA. She conducted important research over many years at the NASA Ames Research Center in the fields of psychology and physiology.

Her research allowed cosmonauts to learn voluntary self-control to bodily responses, and cure motion sickness in space. She has trained space crews and helped improve their performance and wellbeing during missions. She has received several awards for her contributions to technology and development.

Stephanie Kwolek, the inventor of Kevlar, passed away this week at age 90

“A true pioneer for women in science,” passed away on Wednesday, reported the New York Times. As a DuPont scientist, Stephanie Kwolek is credited for inventing Kevlar in 1964, a fiber that has radically improved police and military body armor since its creation.   

Kwolek died at age 90 in hospice care at St. Francis Hospital in Wilmington, Del. She leaves behind a legacy of achievement in science and technology that directly saved an estimated 3,000 lives of police officers over the past four decades.

Teaming with Bots!

‪NSF-funded‬ Northwestern University roboticist Mike Rubenstein is helping NSF’s Science360 Radio pay homage to the National Robotics Initiative this week. We have his Big Picture Science interview about teeny tiny swarming robots called kilobots: 1.usa.gov/1r5QTz9

Self-assembly enables nature to build complex forms, from multicellular organisms to complex animal structures such as flocks of birds, through the interaction of vast numbers of limited and unreliable individuals. Creating this ability in engineered systems poses challenges in the design of both algorithms and physical systems that can operate at such scales. This work demonstrates programmable self-assembly of complex two-dimensional shapes with a thousand-robot swarm. Photo Credit: Michael Rubenstein, Harvard University
