Extreme power-to-weight ratio and efficiency will be key to electrification of aviation.

Update: The UAE’s Hope Mars orbiter has successfully launched toward the Red Planet on its H-IIA rocket.

The United Arab Emirates will launch its first mission to Mars on a Japanese rocket today, July 19, and you can watch it live online.

Japan boasts one of the longest life expectancies on earth, and it also a world leader in “healthy life expectancy”—the number of years of good health people can expect on average. Since diet is believed to play a key role in a population’s health and longevity, researchers around the world have been studying the benefits of the Japanese diet for some time now.

But what exactly is the Japanese diet? The people of Japan do not dine primarily on sushi, tempura, or other well-known Japanese specialties. Moreover, their eating habits have changed over the years. For our research, we used national surveys to compile weekly menus representative of the Japanese diet at various points in time over the past half century. In the following, we will take a look at the comparative health effects of these menus.

The health benefits of Japanese cooking are widely touted, but what exactly is a healthy Japanese diet? Food scientists in Japan have homed in on the nutritional keys to health and longevity, and their conclusions may bode ill for the younger generation.

Google has begun rolling out a feature that allows you to configure how long it can save data from all of the Google services you use, like maps, search and everything you do online. Until now, you had to manually delete this data or turn it off entirely. Deleting it means Google doesn’t always have enough information about you to make recommendations on what it thinks you’ll like, or where you might want to go.

Now, you can tell Google to automatically delete personal information after three months or 18 months. Here’s how you can do that.

Google has a new feature that will automatically delete the data it has on how you use its apps and what you do on the web.

Ripped from the pages of a sci-fi novel, physicists have crafted a wormhole that tunnels a magnetic field through space.

“This device can transmit the magnetic field from one point in space to another point, through a path that is magnetically invisible,” said study co-author Jordi Prat-Camps, a doctoral candidate in physics at the Autonomous University of Barcelona in Spain. “From a magnetic point of view, this device acts like a wormhole, as if the magnetic field was transferred through an extra special dimension.”

The idea of a wormhole comes from Albert Einstein’s theories. In 1935, Einstein and colleague Nathan Rosen realized that the general theory of relativity allowed for the existence of bridges that could link two different points in space-time. Theoretically these Einstein-Rosen bridges, or wormholes, could allow something to tunnel instantly between great distances (though the tunnels in this theory are extremely tiny, so ordinarily wouldn’t fit a space traveler). So far, no one has found evidence that space-time wormholes actually exist. [Science Fact or Fiction? The Plausibility of 10 Sci-Fi Concepts].

The United Arab Emirates is counting down to the launch of its first interplanetary space mission today — one that will send a spacecraft called “Hope” to orbit Mars. The Emirates Mars Mission will aim to provide a global snapshot of the weather on the Red Planet. It will also be a source of pride for the UAE as the country celebrates the 50th anniversary of its founding in December of 2021.

To ensure that Hope is actually at Mars by the anniversary, the UAE must launch this summer. Planetary scientists have a very small window every two years to send spacecraft to Mars, when the Red Planet and Earth closely align on their orbits. If Hope launches in July, the spacecraft will spend the next seven months traveling to Mars, arriving sometime in February — leaving it plenty of time in orbit before the anniversary.

Summary: APOEe4, a gene associated with Alzheimer’s disease risk, doesn’t appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall.

Researchers at McGill University and the Douglas Mental Health University Institute, in collaboration with the StoP-AD Center, have published a new paper in the Journal of Alzheimer’s Disease, examining how a known genetic risk factor for late-onset Alzheimer’s disease (AD) influences memory and brain function in cognitively intact older adults with a family history of AD.

Nanoscale thermal physics guarantees our decline, no matter how many diseases we cure.

It’s first uncrewed flight will take place early 2021 and it is set to launch from NASA’s Kennedy Space Center’s Shuttle Landing Facility in Florida.

Space Perspective is building a balloon that will be able to transport passengers and research equipment to the “edge of space.”

There are several companies looking to enter the emerging “space tourism” marketplace, but Space Perspective sets itself apart with its balloon design, named Spaceship Neptune. This balloon will accompany a pressurized and spacious cabin, creating a comfortable traveling experience for its passengers, according to its maker.
