DNA molecules that can carry out reprogrammable computations, for the first time

Computer design meets potions class: A little of vial 1 and a little of vial 2 yield six-bit computations encoded in DNA Computer scientists at Caltech have designed DNA molecules that can carry out reprogrammable computations, for the first time creating so-called algorithmic self-assembly in which the same “hardware” can be configured to run different

A simple new technique can detect fake drugs from a video taken as the sample undergoes a disturbance 

“Chronoprints” can identify a sample from a video taken as it reacts to disturbance If we could tell authentic from counterfeit or adulterated drugs and foods just by looking at them, we could save money and lives every year, especially in the developing world, where the problem is worst. Unfortunately, the technologies that can detect

Nanoparticle robots start to come together as ‘gray goo’

Researchers create new kind of robot composed of many simple particles with no centralized control or single point of failure The concept of “gray goo,” a robot comprised of billions of nanoparticles, has fascinated science fiction fans for decades. But most researchers have dismissed it as just a wild theory. Current robots are usually self-contained

A toilet seat that can detect congestive heart failure gets ready to be seated

Researchers developed the seats to measure biometrics during ‘natural’ processes With 1 million new cases of congestive heart failure diagnosed each year, a revolutionary product is making it easier for hospitals to monitor patients with the condition in the comfort of their own homes. A toilet-seat based cardiovascular monitoring system created by a team of

Calling for a compact fusion pilot plant to generate electricity at the lowest possible cost

Can tokamak fusion facilities, the most widely used devices for harvesting on Earth the fusion reactions that power the sun and stars, be developed more quickly to produce safe, clean, and virtually limitless energy for generating electricity? Physicist Jon Menard of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has examined that

A new sensor can detect brain disorders in seconds

Using nanotechnology, UCF researchers have developed the first rapid detector for dopamine, a chemical that is believed to play a role in various diseases such as Parkinson’s, depression and some cancers. Studies show too much dopamine could be associated with some cancers, while low dopamine could be associated with Parkinson’s disease and depression. The new

The ability to levitate objects on many scales with light

Nanoscale patterning could enable precise manipulation of objects on many scales. Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects’ surfaces. Though still theoretical, the work is a step toward developing a spacecraft that could reach the nearest planet outside of

Soft robotics potential: New liquid metals can move and stretch both horizontally and vertically

In the blockbuster Terminator movie franchise, an evil robot morphs into different human forms and objects and oozes through narrow openings, thanks to its “liquid-metal” composition. Although current robots don’t have these capabilities, the technology is getting closer with the development of new liquid metals that can be manipulated in 3D space with magnets. Reported in ACS Applied

Robot helpers for the joy and sorrow of dementia

Caregivers design robots that increase joyful moments and reduce emotional stress Building robots that can help people with dementia has been a longtime goal for roboticists. Yet until now, no one has sought to survey informal caregivers, such as family members, about what characteristics and roles these robots should have. A team of scientists at

Phase-switching liquids can delay ice and frost formation up to 300 times longer than state-of-the-art coatings

Most techniques to prevent frost and ice formation on surfaces rely heavily on heating or liquid chemicals that need to be repeatedly reapplied because they easily wash away. Even advanced anti-icing materials have problems functioning under conditions of high humidity and subzero conditions, when frost and ice formation go into overdrive. Now, researchers from the

Creating hydrogen fuel from seawater

Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. A Stanford-led team has now developed a way to harness seawater – Earth’s most abundant source – for chemical energy. Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and saltwater

World’s first online polygraph for text messaging gets it right between 85 to 100 percent of the time

Can you spot a liar? It’s tricky enough in face-to-face conversations that offer facial expressions, gestures and tone of voice because those physical cues add context. Spotting a liar gets even tougher in blind computer conversations. Florida State University researcher Shuyuan Ho wants to shed those blinders by creating a revolutionary online polygraph. “The future
