Compact dark object search: Scanning Earth's core with superconducting gravimeters

Physics theory suggests that the universe is made up in great part by a type of matter that does not emit, absorb or reflect light, and hence cannot be observed using conventional detection methods. This type of matter, referred to as dark matter, has so far never been experimentally observed or detected.

Scientists predict state of matter that can conduct both electricity and energy perfectly

Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency—never losing any to heat or friction.

When plasmons reach atomic flatland

Researchers from the MPSD and the Lawrence Berkeley National Laboratory (LBNL) in the United States have discovered a significant new fundamental kind of quantum electronic oscillation, or plasmon, in atomically thin materials. Their work has now been published in Nature Communications. It has potential implications for novel imaging techniques and photochemical reactions at the nanoscale.

Scientists crack the mystery of liquid light interactions in organic materials

A team of scientists from the Hybrid Photonics Laboratory at the Skolkovo Institute of Science and Technology (Skoltech) and the University of Sheffield (UK) made a breakthrough in understanding nonlinear physics of the strong interaction of organic molecules with light. Principles of strong light matter interaction open new horizons of ultra-fast and low energy all-optical data processing. The findings were published in Communications Physics and featured in the February issue of Nature Physics.

A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the MPSD and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Astronomy & Space news

XMM-Newton reveals giant flare from a tiny star

A star of about eight percent the Sun's mass has been caught emitting an enormous 'super flare' of X-rays—a dramatic high-energy eruption that poses a fundamental problem for astronomers, who did not think it possible on stars that small.

How better propulsion systems can improve space exploration

Aero/Astro engineer Ken Hara is developing computer models to help make a little-known, but widely-used thruster engine more suitable for long-distance missions.

Mars InSight lander to push on top of the 'mole'

After nearly a year of trying to dig into the Martian surface, the heat probe belonging to NASA's InSight lander is about to get a push. The mission team plans to command the scoop on InSight's robotic arm to press down on the "mole," the mini pile driver designed to hammer itself as much as 16 feet (5 meters) down. They hope that pushing down on the mole's top, also called the back cap, will keep it from backing out of its hole on Mars, as it did twice in recent months after nearly burying itself.

Technology news

A light-sensitive compound enables heatless membrane modulation in photoswitches

Optical technologies that can be used to modulate neuronal activity are opening up exciting possibilities for research in neuroscience and biology. Optical tools allow neuroscientists to excite and inhibit neurons or areas of the brain at will. They can thus be used to investigate the function of specific brain circuits or regions, as well as to identify new potential treatments for neurological and psychiatric diseases.

Offshore wind farms could power much of coastal China: study

Under the Paris Climate Agreement, China committed to rely on renewable resources for 20 percent of its energy needs by 2030. Currently, the country is on track to double that commitment, aiming to hit 40 percent by the next decade. Wind power is critical to achieving that goal. Over the past 20 years, China's wind power capacity has exploded from 0.3 gigawatts to 161 gigawatts.

How a road sign trick sent a self-driving car into high-speed mode

Can a little strip of tape on a 35-mile-per-hour speed limit sign cause a self-driving car to accelerate? Yes—and press attention, too. Researchers from security company McAfee wanted to see if they could dupe a Tesla car into thinking the speed limit was different than posted, and they succeeded.

Scientists finally confirm a 50-year-old theory in mechanics

An experiment by EPFL researchers has confirmed a theory that has been used in mechanics for over half a century—despite never having been fully validated. The team could now use the theory in bolder and more innovative ways in their quest to develop ever better energy systems.

Emotion recognition has a privacy problem—here's how to fix it

With devices listening everywhere you go, privacy concerns are endemic to advancing technology. Especially sensitive are different techniques powered by audio from your smartphones and speakers, putting consumers in a constant cost-benefit analysis between privacy and utility.

Firm wants to recover the Titanic's iconic telegraph machine

The salvage firm that has plucked silverware, china and gold coins from the wreckage of the Titanic now wants to recover the Marconi Wireless Telegraph Machine that transmitted the doomed ship's increasingly frantic distress calls.

Right now, drones are flying over wildlife parks in South Africa, equipped with thermal infrared cameras and smart automatic detection systems that can identify potential poachers. If a poacher is spotted, the drone can alert nearby rangers and flash its lights to send up an alarm.

Turns out there is such a thing as TMI: More information doesn't necessarily help people make better decisions

Making everyday decisions seems easy enough. People know basic information about health and finances that they can use to inform their decision making. But new research from Stevens Institute of Technology suggests that too much knowledge can lead people to make worse decisions, pointing to a critical gap in our understanding of how new information interacts with prior knowledge and beliefs.
