They’re tiny but have a knack for saving human life.
The Belgian non-profit organization APOPO trains rats to help earthquake survivors. Called RescueRATs, these rats are preparing to save those under the earthquake debris with their high-tech backpacks on their backs.
As CNN reported, “Rats are typically quite curious and like to explore — and that is key for search and rescue,” says Donna Kean, a behavioral research scientist and leader of the project. She also adds that they train rats because they have a good sense of smell and can easily fit into small spaces.
How are the rats trained?
Tesla is rumored to be looking to invest in Nuevo Leon, a Mexican state bordering Texas, as CEO Elon Musk meets with the governor.
Earlier this year, people crossing the border between Texas and Nuevo Leon were surprised to see not just the usual marked lanes for cars and trucks but also one marked “Tesla” – pictured above.
We ended up finding out that Tesla had struck a deal with the state of Nuevo Leon to have its own lane at the border crossing in order to reduce wait times for cargo going through the border. Or at least that was the explanation of Ivan Rivas, the economy minister of Nuevo Leon.
Bill Gates founded Breakthrough Energy and has recently announced that its first Catalyst project funding will come in the form of a $50 million grant to LanzaJet’s Freedom Pines Fuels sustainable aviation fuel (SAF) plant in Soperton, Georgia.
Breakthrough Energy Catalyst is a unique program that brings together businesses and nonprofits to fund key first-of-its-kind commercial-scale projects that speed up the deployment of essential technologies.
Most efforts so far have relied on external heating and cooling systems, but these add a lot of bulk and also tend to use up a considerable amount of energy themselves. The researchers’ innovation, outlined in a recent paper in Nature , was to add an extra component to the batteries: a sheet of nickel foil just a few micrometers thick between the stacked electrodes of each cell.
This ultra-thin sheet is used as a heating element, and when a current is passed through it the cell heats up to 149° Fahrenheit in about a minute. This temperature is maintained through charging, but the cell then quickly cools back to room temperature as soon as the current is switched off.
When they tested their approach, the researchers found that they could charge a 265 watt-hour battery to 70 per cent in 11 minutes. They also showed that heating the battery didn’t seriously affect its lifetime, as it survived 2,000 cycles of charging, which would provide enough energy to drive more than 500,000 miles overall.
A collaboration between the National Renewable Energy Laboratory, the Massachusetts Institute of Technology, and Washington State University opens the door to sustainable jet fuel.

The Indian Electric Vehicle market is set to reach a sales volume of 10.8 lakh units by 2025. However, these vehicles are currently at a high price and are not affordable to consumers in low-income categories.
To bridge this gap, a team of seven students at the KL University, Hyderabad have retrofitted an old and discarded bike into an EV.
“We also added futuristic features including wireless charging and cell balancing, which ensures equalised charging,” says Charan Sai (21), a fourth-year student of Electronics and Electrical Engineering, and the lead of the project.
The apparent lovechild between a helicopter and a ramjet, the Focke-Wulf Triebflügel might just be the oddest aircraft you’ve ever seen.
In the closing months of WWII, the Germans were experimenting with some very fascinating aircraft designs, like the Focke-Wulf Triebflügel.
Part helicopter and part conventional plane, this aircraft used ramjets to turn its unique rotor design. Thankfully for the Allies, it never saw the light of day.
In 1944, the indestructible and unbeatable reputation of the German Army was in tatters. Under pressure from the East and West, it was gradually being pushed back to the German homeland.
The first in the world to do so.
Researchers at the North University of China have successfully completed the test of a Hyperloop-like train system that runs trains in a low vacuum environment inside a tube, local news outlet, China Daily.
In theory, the system can be used for transporting people as well as goods and consists of long tubes that maintain a low vacuum to allow transport with minimal air resistance.

That’s what Musk announced during Tesla’s Q3 2022 earnings call.
The third vehicle platform for Tesla, following the big one supporting the Model S and X and the small one supporting the Model 3 and Y, has received new information from company CEO Elon Musk.
Customers, investors, and Tesla supporters have been anticipating the company’s introduction of a new vehicle that will be less expensive than the current models for some time.
