Physics shows that imperfections make perfect

Northwestern University researchers have added a new dimension to the importance of diversity.

Ultrafast camera takes 1 trillion frames per second of transparent objects and phenomena

A little over a year ago, Caltech's Lihong Wang developed the world's fastest camera, a device capable of taking 10 trillion pictures per second. It is so fast that it can even capture light traveling in slow motion.

Laser diode emits deep UV light

Nagoya University scientists, in cooperation with Asahi Kasei Corporation, have designed a laser diode that emits deep-ultraviolet light, and have published a paper in the journal Applied Physics Express.

LHCb explores the beauty of lepton universality

The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding—a possible difference in the behavior of different types of lepton particles—chimes with other previous results. If confirmed, as more data are collected and analyzed, the results would signal a crack in the Standard Model.

Record-breaking terahertz laser beam

Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry. However, radiation in the terahertz range is extremely difficult to generate. Scientists at TU Wien have now succeeded in developing a terahertz radiation source that breaks several records: it is extremely efficient, and its spectrum is very broad—it generates different wavelengths from the entire terahertz range. This opens up the possibility of creating short radiation pulses with extremely high radiation intensity. The new terahertz technology has now been presented in the journal Nature Communications.

Platelets instead of spheres make screens more economical

ETH scientists have further developed QLED technology for screens. They have produced light sources that for the first time emit high-intensity light in only one direction. This reduces scattering losses, which makes the technology extremely energy efficient.

New ORNL software improves neutron spectroscopy data resolution

Neutron spectroscopy is an important tool for studying magnetic and thermoelectric properties in materials. But often the resolution, or the ability of the instrument to see fine details, is too coarse to clearly observe features identifying novel phenomena in new advanced materials.

Designing lasers based on quantum physics

A five-country research team coordinated by Germán J. de Valcárcel Gonzalvo, Professor of Optics at the University of Valencia, has developed a new theory —the coherent master equation— that describes the behavior of pulsed lasers based on fast materials and highlights its effects of quantum coherence (the ability of material and light electrons to oscillate in unison for some time). These lasers can emit intense pulses of light of one billionth of a second at a constant rate and have great technological and scientific impact.

Astronomy & Space news

BSNIP project releases spectra of more than 200 Type Ia supernovae

The Berkeley Supernova Ia Program (BSNIP) has released a dataset containing over 600 spectra of 242 Type Ia supernovae (SNe Ia). The new data release, available for astronomers worldwide, was presented in a paper published January 9 on the arXiv pre-print repository.

Rough seas delay escape test for SpaceX crew capsule

Rough seas prompted SpaceX on Saturday to delay the emergency escape test of its new crew capsule by a day.

SpaceX launches, destroys rocket in astronaut escape test

SpaceX completed the last big test of its crew capsule before launching astronauts in the next few months, mimicking an emergency escape shortly after liftoff Sunday.

Heat wave signals the growth of a stellar embryo

An international research team with the Max Planck Institute for Astronomy (MPIA) participating has detected a propagating heat wave near a massive protostar. It confirms the scenario that such objects grow in bursts. This wave became visible by observing naturally generated microwave lasers, whose spatial arrangement changed unexpectedly rapid.

ESA opens oxygen plant, making air out of moondust

ESA's technical heart has begun to produce oxygen out of simulated moondust.

First results from the Dark Energy Survey

The Dark Energy Survey (DES) program uses the patterns of cosmic structure as seen in the spatial distribution of hundreds of millions of galaxies to reveal the nature of "dark energy," the source of cosmic acceleration. Since it began in 2013, DES has mapped over 10 percent of the sky with a digital camera containing 570 million pixels and five optical filters that provide galaxy colors to estimates redshift distances. CfA astronomers are part of a team of over 400 scientists in seven countries working on DES, and last year it released the first set of data.

No astrovans for SpaceX, crews riding to rockets in Teslas

Astronauts launched by SpaceX in coming months will ride to their rockets in high fashion. Instead of using a retro-style astrovan, SpaceX crews will travel to the launch pad in Tesla sports cars.

SpaceX in 'perfect' test of Crew Dragon emergency abort system

SpaceX successfully tested its emergency abort system on an unmanned spacecraft moments after launch Sunday, according to a live broadcast of the event, the last major test before it plans to send NASA astronauts to the International Space Station.

A brain transplant for one of Australia's top telescopes

Technology news

M-Hubo: A wheeled humanoid robot to assist humans with simple daily tasks

Researchers worldwide are now training robotic agents to assist humans in a variety of manual tasks, including cooking and moving objects. While many of these robots have achieved promising results, most of them are still unable to complete the tasks assigned to them as quickly as a human being would.

New organic-metal oxide transistors with high operational stability

Metal oxide thin-film transistors (TFTs), which are built by depositing thin films of an active metal oxide-based semiconducting material on a supporting substrate, have become widely used over the past few years, particularly in organic light-emitting diode displays. Most commercially available devices incorporating these transistors currently rely on metal oxides processed using physical vapor deposition techniques.

Gradient Li-rich oxide cathode particles for batteries with minimum oxygen release

Lithium-rich transition metal oxide (Li1+XM1-XO2) cathodes have potential for use in Li-ion batteries, powering electronic devices and electric vehicles. These cathodes have a high energy density, typically above 900 Wh kg-1, yet they currently also come with significant limitations.

Could your car seat trick brain with walk feels?

Securing radiological sources on the go

Radioactive materials are a critical tool in a number of industrial applications particularly oil and gas drilling and welding. While these sources are safe and well-regulated for their intended use; if lost or stolen the materials could be used by terrorists to make dirty bombs. The Department of Energy's Pacific Northwest National Laboratory developed and licensed a technology system to keep track of and secure radiological material on the road or at job sites. Golden Security Services of Miami, Florida, will produce and deploy the Mobile Source Transit Security, or MSTS system, starting at several sites in Latin America.
