Essential Science: New perspectives needed for digital health

This week's Essential Science takes a different approach. We cast an eye over developments in digital health, focusing on patient centered technology and the need for what are, at times, neglected areas of science.

Smart computers decode brain activity

Scientists from the University of Freiburg have used artificial neural networks to decode brain activity during performed and imagined movements. This is a further sign that computer science could revolutionize brain research.

Nanocrystal networks for artificial intelligence applications

An engineer's model lays groundwork for a new type of machine-learning device. The model uses nanocrystals to improve artificial intelligence applications.

How to eliminate social bias from artificial intelligence?

Boston - Artificial intelligence is being used to make more decisions that affect our daily lives: whether we get a loan, to mark an exam paper, to analyze evidence in a court case and so on. What happens if the software is socially biased?

New battery is activated by spit

New York - Engineers and microbiologists have invented a new type of battery based on a microbial fuel cells. The battery can be activated by spit and it is intended to be used in extreme conditions.

Using Twitter for big data analytics to analyze disasters

There are 500 million tweets sent every single day. Can some of this data be put to good use, such as aiding communities in responding to a disaster? Researchers think so.

NASA launch of TDRS-M satellite signals the end of an era

The end of an era came about this morning when a United Launch Alliance (ULA) Atlas V rocket roared off the pad with NASA’s newest communications Tracking and Data Relay Satellite M (TDRS-M).

How to safely watch an eclipse

Miami - Everyone who plans to look skyward when the solar eclipse sweeps across the United States on Monday should have the proper protective eyewear, or risk lasting blind spots, experts warn.Regular sunglasses will not do, the US space agency says.

Eclipse-chasers trot the globe, addicted to Moon's shadow

Miami - Eclipse-chasers are a dedicated crew of scientists who travel the globe to catch a few moments in eerie darkness, and even after seeing dozens of eclipses, they say they can't get enough.

Self-healing rubber invented and triggers business interest

Imagine a tire on a freight vehicle that could heal after being punctured, without the need to call out a breakdown service? This is the technology that has been developed by researchers from the Harvard John A. Paulson School in the U.S.

Micromotors created for drug delivery

University of California-San Diego researchers have successfully tested out drug-delivery micromotors to deliver a therapeutic agent to treat bacterial infections of the stomach.

Unexpected discovery leads to new strategy for carbon fixation

Scientists in Japan and China announced last week they had discovered an "unexpected" approach to the capture and storage of carbon dioxide away from the atmosphere while working toward the elusive lithium-air battery.

Ancient species of giant sloth discovered in Mexico

Mexico - Mexican scientists said Wednesday they have discovered the fossilized remains of a previously unknown species of giant sloth that lived 10,000 years ago and died at the bottom of a sinkhole.

'Missing link' bolsters bold theory on dino evolution

Paris - An oddball, vegetarian dinosaur with the silhouette of a flesh-ripping velociraptor, whose fossilised remains were unearthed in southern Chile 13 years ago, is a missing link in dino evolution, researchers said Wednesday.

Diagnostic tool printed for portable disease testing

Scientists from Duke University have used an inkjet printed tool for conducting diagnostic testing for use in point-of-care settings. The aim is to screen patients for markers of specific diseases.

Reducing organ rejections using 'lethal' bacterial enzyme

Researchers have developed a novel type of drug therapy using an enzyme extracted from bacteria that are normally considered harmful. The aim is to use the enzyme to reduce organ rejection rates following kidney transplants.

NASA: let's say something to Voyager 1 on 40th anniversary of launch

Washington - NASA is seeking suggestions from the public for a message to beam far, far out into space to the probe Voyager 1 in time for the 40th anniversary of its launch.

Op-Ed: Women continue to be underrepresented in STEM fields

Despite government campaigns women remain underrepresented in science and technology. Despite what an infamous ex-Google employee wrote, this is nothing innate. The low levels reflect institutional and societal biases.

Flooding and storm extremes to increase with global warming

Researchers at the University of New South Wales, Australia, have done an exhaustive global analysis that shows signs of a radical shift in stream-flow patterns, with more intense flooding in cities along with drier countrysides.
