For wave-particle duality and entanglement, progress is finally possible if we avoid the customary pitfalls

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics.

Researchers develop world's first all-silicon optical transmitter at 100Gbps

Silicon photonics researchers from the Optoelectronics Research Centre (ORC) have demonstrated the first all-silicon optical transmitter at 100Gbps and beyond without the use of digital signal processing.

Understanding astrophysics with laser-accelerated protons

Bringing huge amounts of protons up to speed in the shortest distance in fractions of a second—that's what laser acceleration technology, greatly improved in recent years, can do. An international research team from the GSI Helmholtzzentrum für Schwerionenforschung and the Helmholtz Institute Jena, a branch of GSI, in collaboration with the Lawrence Livermore National Laboratory, U.S., has succeeded in using protons accelerated with the GSI high-power laser PHELIX to split other nuclei and to analyze them. The results have now been published in the journal Nature Scientific Reports and could provide new insights into astrophysical processes.

New optical method paves way to breath test for cancer biomarker

Researchers have developed an extremely sensitive, yet simple optical method for detecting formaldehyde in a person's breath. Because formaldehyde is being studied as a potential biomarker for lung and breast cancer, the new method could one day lead to an inexpensive and fast way to screen for cancer.

Analysis paves way for more sensitive quantum sensors

Quantum sensors can measure extremely small changes in an environment by taking advantage of quantum phenomena like entanglement, where entangled particles can affect each other, even when separated by great distances.

Novel analytic approach enhances nuclear magnetic resonance signal detection in previously 'invisible' regions

First introduced into wide use in the middle of the 20th century, nuclear magnetic resonance (NMR) has since become an indispensable technique for examining materials down to their atoms, revealing molecular structure and other details without interfering with the material itself.

Making the best decision: Math shows diverse thinkers equal better results

Whether it is ants forming a trail or individuals crossing the street, the exchange of information is key in making everyday decisions. But new Florida State University research shows that the group decision-making process may work best when members process information a bit differently.

Ultracompact metalens microscopy breaks FOV constraints

The pursuit of ever-higher imaging resolution in microscopy is coupled with growing demands for compact portability and high throughput. While imaging performance has improved, conventional microscopes still suffer from the bulky, heavy elements and architectures associated with refractive optics. Metalenses offer a solution: they're ultrathin, ultralight, and flat, and benefit from lots of recent research that has improved their efficiency, FOV, and polarization functionalities.

Highly sensitive detection of circularly polarized light without a filter

SpaceX launches four astronauts to ISS

Four astronauts were successfully launched on the SpaceX Crew Dragon "Resilience" to the International Space Station on Sunday, the first of what the US hopes will be many routine missions following a successful test flight in late spring.

Mars is getting a new robotic meteorologist

Mars is about to get a new stream of weather reports, once NASA's Perseverance rover touches down on Feb. 18, 2021. As it scours Jezero Crater for signs of ancient microbial life, Perseverance will collect the first planetary samples for return to Earth by a future mission. But the rover will also provide key atmospheric data that will help enable future astronauts to the Red Planet to survive in a world with no breathable oxygen, freezing temperatures, planet wide dust storms, and intense radiation from the sun.

Orbits of ancient stars prompt rethink on Milky Way evolution

Theories on how the Milky Way formed are set to be rewritten following discoveries about the behavior of some of its oldest stars.

Weather on Jupiter and Saturn may be driven by different forces than on Earth

A trio of researchers, two with Harvard University, the other the University of Alberta, has found evidence that weather on Saturn and Jupiter may be driven by dramatically different forces than weather on Earth. In their paper published in the journal Science Advances, Rakesh Kumar Yadav, Moritz Heimpel and Jeremy Bloxham describe computer simulations showing that major weather systems on Jupiter and Saturn might be driven by internal rather than external forces, resulting in outcomes such as the formation of large anticyclones like Jupiter's famous red spot.

Cosmic flashes come in all different sizes

By studying the site of a spectacular stellar explosion seen in April 2020, a Chalmers-led team of scientists have used four European radio telescopes to confirm that astronomy's most exciting puzzle is about to be solved. Fast radio bursts, unpredictable millisecond-long radio signals seen at huge distances across the universe, are generated by extreme stars called magnetars—and are astonishingly diverse in brightness.

Texas astronomers revive idea for 'Ultimately Large Telescope' on the moon

A group of astronomers from The University of Texas at Austin has found that a telescope idea shelved by NASA a decade ago can solve a problem that no other telescope can: It would be able to study the first stars in the universe. The team, led by NASA Hubble Fellow Anna Schauer, will publish their results in an upcoming issue of The Astrophysical Journal.

SpaceX crew flight delayed; Musk gets mixed COVID-19 results

SpaceX delayed its second astronaut flight by a day because of high wind and weather conditions that could jeopardize the recovery and recycling of the rocket booster, pushing the launch to Sunday.

Cable failures endanger renowned Puerto Rico radio telescope

The giant, aging cables that support one of the world's largest single-dish radio telescopes are slowly unraveling in this U.S. territory, pushing an observatory renowned for its key role in astronomical discoveries to the brink of collapse.

Scientists expand space instrument's capabilities

A new study by Southwest Research Institute scientists describes how they have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX now uses two different dating approaches based on rubidium-strontium and lead-lead geochronology methods. The instrument uses laser ablation resonance ionization mass spectrometry (LARIMS) to obtain dates using these methods.

Technology news

An origami-inspired robotic fingertip with shape-morphing capabilities

To perform tasks that involve moving or handling objects, robots should swiftly adapt their grasp and manipulation strategies based on the properties of these objects and the environment surrounding them. Most robotic hands developed so far, however, have a fixed and limiting structure; thus, they can perform a limited number of movements and can only grasp specific types of objects.

Designing layered oxide materials for sodium-ion batteries

Lithium cobalt oxide is a layered metal oxide that has attracted great attention to develop rechargeable batteries. Sodium-ion batteries can store grid-scale energy due to the natural abundance of sodium. The composition can determine the structural chemistry for electrochemical performance, however, due to complex compositions, the results are very challenging to predict. In a new report now on Science, Chenglong Zhao and a team of international scientists at the Chinese Academy of Science, China, Harvard University, U.S., Delft University of Technology, the Netherlands, and the University of Toronto, Canada, introduced a "cationic potential" to capture key interactions of layered materials and predict the resulting stacking structures. The team showed how the stacking architecture determined the functional properties to offer solutions towards developing alkali metal layered oxides for electrical energy storage.
