NASA's Mars 2020 mission drops in on Death Valley

On a test flight in Death Valley, California, an Airbus helicopter carried an engineering model of the Lander Vision System (LVS) that will help guide NASA's next Mars mission to a safe touchdown on the Red Planet. During the flight - one in a series—the helicopter (which is not part of the mission and was used just for testing) and its two-person crew flew a pre-planned sequence of maneuvers while LVS collected and analyzed imagery of the barren, mountainous terrain below.

Dead roots, not just waves, account for marsh losses in gulf

A new Duke University-led study finds that the death of marsh plants due to disturbances like the heavy oiling from the Deepwater Horizon oil spill can double the rate of shoreline erosion in hard-hit marshes.

CycleMatch: a new approach for matching images and text

Researchers at Leiden University and the National University of Defense Technology (NUDT), in China, have recently developed a new approach for image-text matching, called CycleMatch. Their approach, presented in a paper published in Elsevier's Pattern Recognition journal, is based on cycle-consistent learning, a technique that is sometimes used to train artificial neural networks on image-to-image translation tasks. The general idea behind cycle-consistency is that when transforming source data into target data and then vice versa, one should finally obtain the original source samples.

Finding the cause of capacity loss in a metal-oxide battery material

Because of their high energy-storage density, materials such as metal oxides, sulfides, and fluorides are promising electrode materials for lithium-ion batteries in electric vehicles and other technologies. However, their capacity fades very rapidly. Now, scientists studying an electrode made of an inexpensive and nontoxic iron-oxide material called magnetite have proposed a scenario—described in the May 20 online issue of Nature Communications—that explains why.

World celebrates centenary of confirmation of relativity

Celebrations are underway across the globe to commemorate 100 years since a UK-led expedition confirmed Einstein's general theory of relativity. The theory fundamentally changed our understanding of physics and astronomy, and underpins critical modern technologies such as the satellite-based Global Positioning System (GPS). A series of public events in the UK and around the world will mark this seminal anniversary.

AlterEgo opens silent spring of computer connections via wearable

OK, we get it. Artificial intelligence experts are on a fast clip from year to year, month to month, showing off what their research can promise. But could it be that we have reached that stage in human-computer interaction, where you can think of a question —— without saying a word— and the machine will respond with the answer?

If you could learn every disease your child could possibly develop in life, would you?

Newborn screening is required in the U.S. and differs slightly depending on which state you live in. For the most part, it's done before a newborn baby leaves the hospital and includes a blood test that screens for 30-50 serious health problems that usually arise in infancy or childhood, and could hinder normal development.

Don't overdo omega-6 fat consumption during pregnancy

In Western societies, we are eating more omega 6 fats, particularly linoleic acid, which are present in foods such as potato chips and vegetable oil. Other research has shown that linoleic acid can promote inflammation and may be associated with an increased risk of heart disease.
