“Five strangers were pulled together” in an engineering challenge to find a solution to a real-world problem.
Engineering researchers of an innovative academy program have designed a Submersible Remotely Operated Vehicle (SROV) in a span of six weeks after accepting the U.K. Navy’s challenge.
“I was skeptical at first that we could pull off such an ambitious project within the timeframe,” said Dylan Brennan, project team lead, a nuclear graduate working for Jacobs.

Earthquakes are almost impossible to predict. Luckily, engineers have come up with some amazing ways to protect people the next time one might strike.

Illinois Institute of Technology Assistant Professor of Chemical Engineering Mohammad Asadi has developed solutions to two major problems facing lithium-air batteries. Lithium-air batteries hold more energy in a smaller battery size than their more common counterpart, the lithium-ion battery, but until now, lithium-air batteries have been overlooked in commercial applications because lithium-air batteries tended to die after fewer recharges and require a lot more energy to charge than can be generated by the battery later.
After almost a decade working in the oil and gas industry, Asadi turned his focus to carbon dioxide in the atmosphere, particularly caused by the transportation industry, which consumes around 38 to 40 percent of the world’s energy. “With more widespread use of electric vehicles, you can drastically reduce transportation-based carbon emissions,” says Asadi. “But to put more electric vehicles on the road, we’ll need batteries—lots of them.”
Currently, lithium-air batteries are seen as less commercially viable than their counterpart, the lithium-ion battery. However, using lithium-air batteries in electric vehicles has some huge advantages.
In theory, it could mitigate the effects of global warming; but experts are wary.
Make Sunsets, a California-based startup, released weather balloons that carried sulfur particles into the stratosphere which possibly burst there, releasing the chemical, MIT Technology Review.

Recently, a start-up company called Make Sunsets has begun releasing chemicals into the stratosphere as a form of geoengineering that is intended to help climate change. However, many are very hesitant about the startup and the result of what they are doing.
For perspective, geoengineering is when chemical particles are released into the stratosphere to manipulate the weather or climate. The theory is that when sulfur is released into the atmosphere that it mimics a natural process that occurs after volcanoes and that by doing this intentionally, we could ease global warming.
While it isn’t difficult to do this, it is very controversial. The reason for this is that it could potentially have dangerous side effects. Additionally, because some regions could endure worse side effects, it could cause issues across international lines.
A rogue company has started putting aerosols into the stratosphere because it believes it will cool the planet.
The company justifies its actions as necessary to begin to cool the planet’s atmosphere. The scientific community is in disagreement.
Make Sunsets is already attempting to earn revenue for geoengineering, a move likely to provoke widespread criticism.
In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin temperatures. Researchers can use natural quantum systems for low-noise microwave amplification via stimulated emission effects; however, they generate a higher noise at functionalities greater than 1 Kelvin.
In this new work, published in the journal Science Advances, Alexander Sherman and a team of scientists in chemistry at the Technical-Israel Institute of Technology, Haifa, used electron spins in diamond as a quantum microwave amplifier to function with quantum-limited internal noise above liquid nitrogen temperatures. The team reported details of the amplifier’s design, gain, bandwidth, saturation power and noise to facilitate hitherto unavailable applications in quantum science, engineering and physics.
