Highly functional and free-form displays are critical components to complete the technological prowess of wearable electronics, robotics, and human-machine interfaces.
Using light to put a twist on electrons
Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. The right- and left-handed versions can sometimes have different properties,...
Listening to soap bubbles pop reveals the physics behind the bursts
A soap bubble’s swan song is a quiet “pfttt.” Put your ear next to a soap bubble, and you might hear a high-pitched sound as it bursts. Now, scientists have characterized that...
NFL Combine: Ex-Alabama WR Henry Ruggs III runs 4.27-second 40-yard dash
Former Alabama wide receiver Henry Ruggs III ran the fastest 40-yard dash of the prospects who ran on the first day of workouts at the 2020 NFL Combine.
New platform for engineering ribosomes to 'cook new cuisines'
Synthetic biology researchers at Northwestern University have developed a system that can rapidly create cell-free ribosomes in a test tube, then select the ribosome that can perform a certain function.
Famous birthdays for Feb. 28: Mario Andretti, Bernadette Peters
Race car legend Mario Andretti turns 80 and actor Bernadette Peters turns 72, among the famous birthdays for Feb. 28.
Navy: Chinese warship fired laser at U.S. aircraft
A Chinese warship fired a weapons-grade laser at a U.S. naval patrol aircraft in international airspace last week, the U.S. Navy said Thursday, chastising the Asian nation's actions as "unsafe...
'Surfing attack' hacks Siri, Google with ultrasonic waves
Using ultrasound waves propagating through a solid surface, researchers were able to read text messages and make fraudulent calls on a cellphone sitting on a desk up to 30 feet...
Raytheon awarded $90.4M for JMEWS warheads for Tomahawk missiles
Raytheon Missile Systems has received a $90.4 million contract to provide engineering and manufacturing development for the Navy's Joint Multiple Effects Warhead System (JMEWS), the Pentagon announced.
New method converts carbon dioxide to methane at low temperatures
Scientists developed a new method to convert carbon dioxide to methane with an electric field at low temperatures. In comparison to previous methods, this new method can produce any amount...
Handheld vacuums for smaller homes and tighter corners
Suck it up and keep your house clean. (Amazon/)If you live in a smaller apartment or dorm room or simply don’t have enough storage space, a full-sized vacuum isn’t a total necessity....
The best white noise machines for calm nerves and peaceful sleep
Sound machines for better sleep. (Gregory Pappas via Unsplash/)A diffuse sound containing literally every audible frequency at an equal intensity, white noise is a nondescript hiss that’s fantastic for discreetly drowning out random...
Polymers get caught up in love-hate chemistry of oil and water
Researchers have achieved a rare look at the inner workings of polymer self-assembly at an oil-water interface to advance materials for neuromorphic computing and bio-inspired technologies.
Free-floating electrocatalysts outperform tethered ones
Detaching particles from the electrode surface frees them from electrical fatigue
Polymers get caught up in love-hate chemistry of oil and water
Researchers at Oak Ridge National Laboratory and the University of Tennessee achieved a rare look at the inner workings of polymer self-assembly at an oil-water interface to advance materials for...
How to make aziridines from olefins without expensive metals
Double bonds form nitrogen-containing 3-membered rings thanks to a reactive, yet fleeting, oxaziridine intermediate
Tying up molecules as easily as you tie up your laces
Since the 1970s, scientists have been trying to knot molecules together to create new, custom-made mechanical properties, which will give rise to new materials. Today, researchers have developed a simple...
Kinetic pathways of ionic transport in fast-charging lithium titanate
Fast-charging batteries typically use electrodes capable of accommodating lithium continuously by means of solid-solution transformation because they have few kinetic barriers apart from ionic diffusion. One exception is lithium titanate...
Hidden fluid mechanics: Learning velocity and pressure fields from flow visualizations
For centuries, flow visualization has been the art of making fluid motion visible in physical and biological systems. Although such flow patterns can be, in principle, described by the Navier-Stokes...
Ultrafast control of vortex microlasers
The development of classical and quantum information–processing technology calls for on-chip integrated sources of structured light. Although integrated vortex microlasers have been previously demonstrated, they remain static and possess relatively...
Structural insights into immunoglobulin M
Immunoglobulin M (IgM) plays a pivotal role in both humoral and mucosal immunity. Its assembly and transport depend on the joining chain (J-chain) and the polymeric immunoglobulin receptor (pIgR), but...
Structure of the secretory immunoglobulin A core
Secretory immunoglobulin A (sIgA) represents the immune system’s first line of defense against mucosal pathogens. IgAs are transported across the epithelium, as dimers and higher-order polymers, by the polymeric immunoglobulin...
