Storing energy in red bricks
Red bricks -- some of the world's cheapest and most familiar building materials -- can be converted into energy storage units that can be charged to hold electricity, like a...
A new way to fabricate MXene films that block electromagnetic interference
Chemical and biomolecular engineers have demonstrated a novel approach to MXene fabrication that could lead to methods for at-scale production of MXene freestanding films: drop-casting onto prepatterned hydrophobic substrates. Their...
Textron to supply 2 Cessna Grand Caravan aircraft to Rwanda
Textron announced Tuesday that it has received a contract to supply two multi-mission Cessna Grand Caravan aircraft for the Rwanda Defense Force.
Recipe for success -- interaction proteomics become a household item
A research team introduces a new optimized and integrated interaction proteomics protocol that combines two state-of-the art methods to allow rapid identification of protein-protein interactions and more.
X-rays indicate that water can behave like a liquid crystal
Scientists have discovered that water can exhibit a similar behavior like a liquid crystal when illuminated with laser light. This effect originates by the alignment of water molecules, which exhibit...
U.S., Japanese militaries conduct training exercise with B-1 bomber, Reagan Strike Group
The USS Ronald Reagan Carrier Strike Group conducted a bilateral mission with a B-1B Lancer and aircraft from Japan's Air Self-Defense Force near Japan last week, according to the Air...
How airplanes counteract St. Elmo's Fire during thunderstorms
A new study finds windy conditions can weaken St. Elmo's fire, the phenomenon when electrically conductive structures spontaneously emit a flash of blue light, when it's generated by aircraft and...
Physicists cast doubt on neutrino theory
Physicists are raising doubts about the existence of an exotic subatomic particle that failed to show up in twin experiments.
NATO receives 2nd Airbus A330 for fleet of multi-role aircraft
NATO received the second plane in a fleet of multi-role aircraft it's assembling this week.
Long-term risks of joint implants
Using highly complex analytical techniques, a group of researchers were able to observe in detail how different metals are released from joint implants and accumulate in the surrounding bone tissue....
X-rays indicate that water can behave like a liquid crystal
Scientists at Stockholm University have discovered that water can exhibit a similar behavior to that of a liquid crystal when illuminated with laser light. This effect originates by the alignment...
A new way to fabricate MXene films that block electromagnetic interference
The proliferation and miniaturization of electronics in devices, wearables medical implants and other applications has made technologies for blocking electromagnetic interference (EMI) especially important, while making their implementation more challenging....
Car passengers can reduce pollution risk by closing windows and changing route
Drivers and passengers can inhale significantly lower levels of air pollution by setting their vehicle's ventilation systems more effectively and taking a 'cleaner' route to their destination, a new study...
Investigating a thermal challenge for MOFs
To the naked eye, metal organic frameworks (MOFs) look a little like sand. But if you zoom in, you will see that each grain looks and acts more like a...
Look: Emu captured after five days on the loose in England
An emu that escaped from her owner's property in England has been captured after wandering loose for nearly a week.
The best paring knives for cutting, dicing, and peeling
For detail work. (Louis Hansel via Unsplash/)Though it doesn’t get as much attention as larger chef’s knives, a great paring knife can be life-changing. Their size allows them to be nimble workhorses for...
Dog crates to keep your pup safe and comfortable
A second home for Fido. (Tomasz Filipek via Unsplash/)We know it’s never fun to put your pooch in their crate or cage, but it’s unavoidable at times. It’s super important to find...
Two Indians pitchers break COVID-19 protocol; Cardinals-Tigers series suspended
The St. Louis Cardinals have yet to play baseball in August due to a team coronavirus outbreak, while two Cleveland Indians pitchers will miss time due to violations of league...
Using physics to improve root canal efficiency
Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if...
Digital content on track to equal half Earth's mass by 2245
As we use resources, such as coal, oil, natural gas, copper, silicon and aluminum, to power massive computer farms and process digital information, our technological progress is redistributing Earth's matter...
Organocatalyst that controls radical reactions for complex and bulky compound synthesis
Organocatalysts consisting of organic compounds without metal elements are receiving much attention as next generation catalysts in the hope of reducing environmental burden and coping with exhaustion/rising prices of rare...
Baking and Boiling Botnets Could Drive Energy Market Swings and Damage
Evil armies of internet-connected EV chargers, ovens, hot-water heaters, air-conditioners, and other high-wattage appliances could be hijacked to slightly manipulate energy demand, potentially driving price swings and creating financial damage...
3 Questions: Asegun Henry on five “grand thermal challenges” to stem the tide of global warming
More than 90 percent of the world’s energy use today involves heat, whether for producing electricity, heating and cooling buildings and vehicles, manufacturing steel and cement, or other industrial activities....
