The Tesla transformation to a fully integrated design.
Join me and Cory Steuben as he reviews all the different ways Tesla has an advantage over their competitors from manufacturing, the factories, the business model and the team.
The “one-shot” process paves the path for cutting-edge 3D cell culture methods with biomedical engineering applications, claim the scientists.
German scientists have created a new technology that helps them print 3D objects with sound waves.
The design creates pressure fields using several acoustic holograms, which can be used to print solid particles, gel beads, and even living cells, according to the study released on Thursday.

A new North Carolina State University study, performed in collaboration with battery testing researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory, shows that extremely short pulses from a high-powered laser can cause tiny defects in lithium-ion battery materials—defects that can enhance battery performance.
The technique, called nanosecond pulsed laser annealing, lasts for only 100 nanoseconds and is generated by the same type of laser used in modern-day eye surgeries. Researchers tested the technique on graphite, a material widely used in lithium-ion battery anodes, or positive electrodes. They tested the technique in batches of 10 pulses and 80 pulses and compared the differences in current capacity; power is calculated by multiplying voltage by current.
Lithium-ion batteries are widely used in portable electronic devices and electric cars. With further improvements, these batteries could have a major impact on transportation and as storage devices for renewable energy sources like wind and solar.
When Srikanth Singamaneni and Guy Genin, both professors of mechanical engineering and materials science at the McKelvey School of Engineering at Washington University in St. Louis, established a new collaboration with researchers from the School of Medicine in late 2019, they didn’t know the landscape of infectious disease research was about to shift dramatically. In a conference room overlooking Forest Park on a beautiful fall day, the team had one goal in mind: tackle the biggest infectious disease problem facing the world right then.
“Srikanth and I had a vision of a simple, quantitative diagnostic tool, so we connected with infectious disease physicians here at WashU and asked them, ‘What are the most important questions that could be answered if you could get really detailed information cheaply at the point of care?’” said Genin, the Harold and Kathleen Faught Professor of Mechanical Engineering.
“Greg Storch told us that one of the most important challenges facing the field of infectious disease is finding a way to figure out quickly if a patient has a bacterial infection and should get antibiotics or has a viral infection, for which antibiotics will not be effective.”
Scientists at the University of Connecticut Health, Yale University, and Johns Hopkins University have discovered that certain cancer cells possess the ability to evade limitations caused by oxygen deprivation, enabling the cancer cells to continue to grow.
The findings were recently published in the journal Cell Systems. The research was led by Kshitiz, an assistant professor in the Department of Biomedical Engineering, in collaboration with scientists Chi V. Dang from Johns Hopkins and Andre Levchenko from Yale.
Nearly a decade ago, the researchers observed a strange phenomenon while looking at cancer cells under hypoxia—or a lack of oxygen.
Pilonnel noticed that millions watch his videos, but very few actually attempt them. He wants to help people by making replacement parts available.
Users of Apple’s AirPods are well aware that the product they purchased is pretty much disposable. Once the rechargeable battery on the device gives way, there is no way to replace them; you need to buy new AirPods, unless you are ready to do the hard work yourself, with a little help, of course.

I will gladly pay you Tuesday for a hamburger today.
After a long day, you are finally at your favorite restaurant and you order the burger you have been dreaming of the whole time. The burger is gone within minutes, or seconds depending on your appetite. You call the waiter to send compliments to the chef for that delicious burger but are surprised to learn that your burger’s meat has been grown in a laboratory. How would you feel about eating lab-grown meat? Would you even care or does this scenario not make sense because you would have understood in the first bite that you are not eating “real meat”? What is lab-grown meat, anyway?
The company hopes to make the new cars part of the Olympic sport.
Australia-based company Airspeeder, which engineered the world’s first flying electric racing car, is now training its electric pods to be part of the Olympic sport one day.

Juan Andres Guerrero-Saade’s speciality is picking apart malicious software to see how it attacks computers.
It’s a relatively obscure cybersecurity field, which is why last month he hosted a weeklong seminar at Johns Hopkins University where he taught students the complicated practice of reverse engineering malware.

Prime Minister Benjamin Netanyahu has proposed building a network of underground highway systems across the West Bank to enable the maintenance of territorial contiguity for both Israeli settlements and Palestinian towns, The Times of Israel’s sister site, Zman Yisrael, reported Saturday.
Netanyahu is aiming for high-speed tunnels routes designed ostensibly to address the problems of traffic jams and congestion, per the vision of the billionaire Elon Musk, and his engineering firm Boring Company.
Netanyahu presented his plans during a conversation Friday with French investors in Paris at the hotel where he spent the weekend.
