A device developed at the University of Florida for the U.S. military provides protection from mosquitos for an extended period and requires no heat, electricity or skin contact. The controlled-release passive device was designed by Nagarajan Rajagopal, a Ph.D. candidate and Dr. Christopher Batich in UF's Department of Materials Science and Engineering in the Herbert Wertheim College of Engineering.

When most people think about electric vehicles, they think cars. in China, global sales of electric vehicles have surged. Two million EVs were sold in just the first quarter of 2022 — that’s a significant jump from a decade ago when sales hit only 120,000 cars worldwide, the International Energy Agency reported.

Automaker BMW unveiled a pair of concept cars under the name BMW i Vision Dee during its CES 2023 event. The cars interact with drivers through color-changing panels and a front display that creates something like facial expressions.

Enhanced tax credits through the IRA is expected to give carbon capture projects a boost; the IRA offers tax credits of up to $180 per metric ton, up from the $50 per metric ton that was previously offered.

Microplastics are a growing environmental problem, but now researchers in Korea have developed a new water purification system that can filter out these tiny fragments, as well as other pollutants, very quickly and with high efficiency.

Existing body armor can stop shrapnel and bullets from reaching the person wearing it. But it doesn’t absorb a projectile’s kinetic energy, meaning the wearer can still get injured from the force of the blow. Beyond that, most body armor—made from heavy, bulky layers of ceramic and fibers—is only good once, as a strike from a projectile can compromise its structural integrity.

Scientists from Oxford University and the University of Birmingham have made the first bone marrow ‘organoids’ that include all the key components of human marrow. This technology allows for the screening of multiple anti-cancer drugs at the same time, as well as testing personalised treatments for individual cancer patients.

A nuclear fusion reactor has reportedly created more energy than was put into it, for the first time ever. If the experimental results are confirmed, it will prove that fusion is a viable way to meet the planet’s growing energy demands by replicating the reaction that has been occurring at the heart of our sun for billions of years – with some caveats.

A sticky gel plaster containing the yellow pigment in turmeric can patch up punctured lungs in rats. It also seems to help wounds heal when loaded up with sacs of biological molecules. Biodegradable gel patches often need to be glued to the body parts they are intended to help repair and can struggle to follow the movement of organs like lungs as they inflate and deflate.

The U.S. Department of Energy said Sunday it would announce a "major scientific breakthrough" this week, after media reported a federal laboratory had recently achieved a major milestone in nuclear fusion research. The Financial Times reported Sunday that scientists in the California-based Lawrence Livermore National Laboratory (LLNL) had achieved a "net energy gain" from an experimental fusion reactor.

Nanomaterials have at least one of their dimensions (length, width or height) between 1nm to 100nm (see graphic). In the microscopic nano world, properties such as colour, melting point and electrical conductivity are quite different to their larger, macroscopic counterparts that can be seen with the naked eye.

The SKA observatory will be located in two different deserts and will have immense sensitivity. It will bring a new look at the cosmic dawn and many astronomical phenomena. This project started in the 1990s.

New artificial intelligence 'AI' powered smart glasses give deaf or hard-of-hearing people a heads-up display of live, real-time subtitles of their conversation, right in front of their eyes and let them rewind the chat, to read it again. The technology, called XRAI Glass, uses off-the-shelf augmented reality 'AR' glasses that are tethered to a smartphone app with AI driven software that gives the user a new kind of personal assistant, one that remembers what you have forgotten.

A surgical team has used a new type of robot to remove a cancerous tumour from a patient's throat. Gloucestershire Royal Hospital surgeons Simon Higgs and Steve Hornby employed the Versius robot to remove a tumour from Martin Nugent's oesophagus.

SEVENTY-FIVE YEARS is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.

Remember the hydrogen-powered Hyperion XP-1 which made headlines in August 2020 with its impressive specs? Well, the first model from the California-based startup made its public debut at the Los Angeles Auto Show, still looking like a vehicle built by an alien civilization.

High-power radio-frequency electronics are a hot commodity, both figuratively and literally. The transistors needed to amplify 5G and future 6G signals are struggling to handle the thermal load, causing a bottleneck in development. Engineers in the United States and England have teamed up to demonstrate a promising solution—swaddling individual transistors in a blanket of thermally conductive diamond to keep them cool.

Scientists hoping to harness nuclear fusion—the same energy source that powers the Sun and other stars—have confirmed that magnetic fields can enhance the energy output of their experiments, reports a new study. The results suggest that magnets may play a key role in the development of this futuristic form of power, which could theoretically provide a virtually limitless supply of clean energy. While this is an exciting prospect, most experts believe that it will take decades to engineer a working fusion reactor, assuming it is possible at all.

The space elevator — a structure that reaches into the sky — might feel like a distant, farfetched concept, but it could be closer than we think. In an op-ed for Scientific American, Physics professor Stephen Cohen at Vanier College in Montreal, Quebec, said he believes the sci-fi-like technology could be a reality within "the next two or three decades."

The space economy is no longer the sole domain of governments and aerospace and defense companies. The passengers who boarded commercial flights just after World War II didn’t know that air travel would begin to soar over the next decade, nor did the masses who first logged onto the internet in the 1990s realize that computers would one day provide much of their news, entertainment, and social life. And today, few people understand that the space economy—broadly defined as activities in orbit or on other planets that benefit human beings—could soon transform how they live and work.
