Sedimentary, dear Johnson: Is NASA looking at the wrong rocks for clues to Martian life?

In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks.

What's behind the belief in a soulmate?

The United States appears to be in a romantic slump. Marriage rates have plummeted over the last decade. And compared to previous generations, young single people today are perhaps spending more time on social media than actual dating. They are also having less sex.

Experimental brain-controlled hearing aid decodes, identifies who you want to hear

Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

Wearable cooling and heating patch could serve as personal thermostat and save energy

Engineers at the University of California San Diego have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user's skin to a comfortable temperature and keeps it there as the ambient temperature changes. It is powered by a flexible, stretchable battery pack and can be embedded in clothing. Researchers say wearing it could help save energy on air conditioning and heating.

Lunar South Pole Atlas—a new online reference for mission planners

The Lunar and Planetary Institute (LPI), managed by Universities Space Research Association (USRA), has compiled and made available an atlas of the Moon's south pole. Given NASA's recent direction to implement Space Policy Directive-1 landing astronauts at the south pole by 2024, the LPI has compiled a series of maps, images, and illustrations designed to provide context and reference for those interested in exploring this area.

A social perception scheme for behavior planning of autonomous cars

To navigate dynamic environments, autonomous vehicles (AVs) should be able to process all information available to them and use it to generate effective driving strategies. Researchers at the University of California, Berkeley, have recently proposed a social perception scheme for planning the behavior of autonomous cars, which could help to develop AVs that are better equipped to deal with uncertainty in their surrounding environment.

Researchers develop novel framework for tracking developments in optical sensors

Plasmonics and photonics have been drawing attention in both academia and industry due to their use in an extensive range of applications, one of which includes optical sensing. The development of optical sensing technology not only contributes to the scientific research community as a versatile tool, but also offers substantial commercial value for smart city and Internet of Things (IOT) applications due to its energy efficiency, lightweight, small size and suitability for remote sensing. Reinforcing its significance, Scientific American identified plasmonic sensing as one of the top 10 emerging technologies of 2018.

Scientists capture first-ever video of body's safety test for T-cells

For the first time, immunologists from The University of Texas at Austin have captured on video what happens when T-cells—the contract killers of the immune system, responsible for wiping out bacteria and viruses—undergo a type of assassin-training program before they get unleashed in the body. A new imaging technique that allowed for the videos, described today in the journal Nature Communications, holds promise for the fight against autoimmune disorders such as Type 1 diabetes.

Here's why your internet may be delivered by a drone someday soon

As the pilotless flying wing came in for a landing, winds suddenly picked up. Facebook Inc.'s Aquila drone—powered by the sun and wider than a Boeing 737 jetliner—struggled to adjust. Just before landing, part of the right wing broke off.

Metals influence C-peptide hormone related to insulin

Metals such as zinc, copper and chromium bind to and influence a peptide involved in insulin production, according to new work from chemists at the University of California, Davis. The research is part of a new field of "metalloendocrinology" that takes a detailed look at the role of metals in biological processes in the body.

Human capital benefits of military boost economy by billions

A recent study from North Carolina State University finds that U.S. government spending on military personnel has a positive impact on the nation's human capital—essentially improving the American workforce. Using a new computer model, the study estimates the economic impact of this human capital improvement to be $89.8 billion for 2019 alone.

Mission control 'saves science'

Every minute, ESA's Earth observation satellites gather dozens of gigabytes of data about our planet—enough information to fill the pages on a 100-metre long bookshelf. Flying in low-Earth orbits, these spacecraft are continuously taking the pulse of our planet, but it's teams on the ground at ESA's Operations Centre in Darmstadt, Germany, that keep these explorers afloat.

Black women more likely to die of breast cancer, especially in the South

When Felicia Mahone was 27, she felt her breast and found a mass. Breast cancer had killed nearly all the women in her family—her mother, two aunts and two cousins. Her doctor, though, downplayed the lump, assuring her everything would be all right.
