November 12, 2019 |

Dallas, TX – Frequent cannabis (marijuana) use among young people was linked to an increased risk of stroke and people diagnosed with cannabis use disorder were more likely to be hospitalized for heart rhythm disturbances (arrhythmias), according to two new preliminary studies to be presented at the American Heart Association’s Scientific Sessions 2019 — November 16th -18th in Philadelphia.

Young people who reported using cannabis frequently had higher risk of having a stroke, according to a Virginia study. (American Heart Association)

NASA Shapeshifter transforming robot could one day explore Saturn’s moon Titan

September 27, 2019 |

Pasadena, CA – NASA mini robots that can roll, fly, float and swim, then morph into a single machine? Together they form Shapeshifter, a developing concept for a transformational vehicle to explore treacherous, distant worlds.

In a dusty robotics yard at NASA’s Jet Propulsion Laboratory in Pasadena, California, the Shapeshifter team is testing a 3D-printed prototype of this unusual explorer. A contraption that looks like a drone encased in an elongated hamster wheel rolls across the yard, then splits in half.

American Heart Association says Protect your Heart in the Heat

September 2, 2019 |

Dallas, TX – The American Heart Association, the world’s leading nonprofit organization focused on heart and brain health for all, is urging people to take precautions to protect their hearts in hot weather.
 
Hot temperatures and high humidity can cause a dangerous heat index that can be hard on the heart. Dehydration causes the heart to work harder, putting it at risk.

NASA to Test Antibiotics effectiveness on E. coli in Space

November 26, 2017 |

Written by Frank Tavares
NASA’s Ames Research Center

Mountain View, CA – Ever wonder what would happen if you got sick in space? NASA has sent bacteria samples into low-Earth orbit to help find out.

One of the agency’s latest small satellite experiments is the E. coli Anti-Microbial Satellite, or EcAMSat, which will explore the genetic basis for how effectively antibiotics can combat E. coli bacteria in the low gravity of space. This CubeSat – a spacecraft the size of a shoebox built from cube-shaped units – has just been deployed from the space station, and may help us improve how we fight infections, providing safer journeys for astronauts on future voyages, and offer benefits for medicine here on Earth.

EcAMSat contains this experimental module, inside which the E. coli are stored. Nutrients, the antibiotic, a special dye and waste are stored in bags connected through a series of tubes to the microfluidics card – a device storing small pools of liquid containing the bacteria.

American Heart Association says Shock from Heart Device often triggers further Health Care needs

February 21, 2017 |

American Heart Association Rapid Access Journal Report

Dallas, TX – A shock from an implantable cardioverter defibrillator (ICD) may trigger an increase in health care needs for many people, regardless whether the shock was medically necessary, according to a new study published in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.

ICDs save people from sudden cardiac death by delivering a shock to restore a normal rhythm when the lower chambers of their heart, or ventricles, beat erratically.

NASA tests Hedgehog robots designed to operate on an Asteroid or Comet

September 6, 2015 |

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

Pasadena, CA – Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can’t operate upside-down. But on a small body, such as an asteroid or a comet, the low-gravity conditions and rough surfaces make traditional driving all the more hazardous.

Enter Hedgehog: a new concept for a robot that is specifically designed to overcome the challenges of traversing small bodies. The project is being jointly developed by researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California; Stanford University in Stanford, California; and the Massachusetts Institute of Technology in Cambridge.

While a Mars rover can’t operate upside down, the Hedgehog robot can function regardless of which side lands up. (NASA/JPL-Caltech/Stanford)

NASA uses Cubesats to advance Radio Science

Pasadena, CA – Next time you tune in to public radio or the hottest Top 40 radio station, you’ll be using some of the same tools NASA uses to unravel the mysteries of the universe.

Courtney Duncan, an engineer at NASA’s Jet Propulsion Laboratory in Pasadena, California, says studying radio waves coming from a known source in space can reveal a great deal about objects in our solar system.

Of course, there is nothing new in that. NASA scientists have been turning the transmissions of their spacecraft’s radio into scientific gold since almost the beginning of the space age. And ground-based astronomers have not been left outside of the radio spectrum looking in.

The Low Mass Radio Science Transponder-Satellite (LMRST-Sat) is about 4 by 4 by 12 inches (10 by 10 by 30 centimeters) in size and weighs as much as a kid’s bowling ball (8 pounds or, 4 kilograms). The CubeSat is a collaboration between NASA’s Jet Propulsion Laboratory in Pasadena, California, and Stanford University’s Space and Systems Development Laboratory, Stanford, California.

NASA’s QuikScat satellite finds Beijing China has Quadrupled in Size

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, CA – A new study by scientists using data from NASA’s QuikScat satellite has demonstrated a novel technique to quantify urban growth based on observed changes in physical infrastructure.

The researchers used the technique to study the rapid urban growth in Beijing, China, finding that its physical area quadrupled between 2000 and 2009.

A team led by Mark Jacobson of Stanford University, Palo Alto, California, and Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, California, used data from QuikScat to measure the extent of infrastructure changes, such as new buildings and roads, in China’s capital.

Data from NASA’s QuikScat satellite show the changing extent of Beijing between 2000 and 2009 through changes to its infrastructure. Gray and black indicate buildings, with the tallest and largest buildings in the city’s commercial core appearing lighter gray. Other colors show changes in areas not yet urbanized (for example, clearing land or cutting down trees), with the rate of change indicated by color. Blue-green indicates the least change, yellow-orange more change, and red the greatest change. (NASA/JPL-Caltech)

NASA scientists test Gecko like Grippers in Microgravity

Pasadena, CA – There are no garbage trucks equipped to leave the atmosphere and pick up debris floating around the Earth. But what if we could send a robot to do the job?

Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, are working on adhesive gripping tools that could grapple objects such as orbital debris or defunct satellites that would otherwise be hard to handle.

The gecko gripper project was selected for a test flight through the Flight Opportunities Program of NASA’s Space Technology Mission Directorate. As a test, researchers used the grippers in brief periods of weightlessness aboard NASA’s C-9B parabolic flight aircraft in August.

This is an image of a gecko foot. Researchers at NASA’s Jet Propulsion Laboratory have developed a gripping system based on the way that gecko feet are able to stick to surfaces. Just as a gecko’s foot has tiny adhesive hairs, the JPL devices have small structures that work in similar ways. (Wikimedia Commons)
