Improving Therapeutic Vaccination against Hepatitis B—Insights from Preclinical Models of Immune Therapy against Persistent Hepatitis B Virus Infection

Posted by in category: biotech/medical

Chronic hepatitis B affects more than 250 million individuals worldwide, putting them at risk of developing liver cirrhosis and liver cancer. While antiviral immune responses are key to eliminating hepatitis B virus (HBV) infections, insufficient antiviral immunity characterized by failure to eliminate HBV-infected hepatocytes is associated with chronic hepatitis B. Prophylactic vaccination against hepatitis B successfully established protective immunity against infection with the hepatitis B virus and has been instrumental in controlling hepatitis B. However, prophylactic vaccination schemes have not been successful in mounting protective immunity to eliminate HBV infections in patients with chronic hepatitis B.

Scientists learn from creepy skin parasites how to suppress pain

Posted by in category: biotech/medical

Painless lesions investigated in mice

Now, for the first time, researchers have looked into the lesions on mouse skin to assess if there are any metabolic signalling pathways that are responsible for thwarting pain. The aim is to hopefully use this mechanism to help people suffering from debilitating pain through the development of non-narcotic pain medications.

“No one knows why these lesions are painless – but it has been thought that the parasite somehow manipulates the host physiological system,” said Abhay Satoskar, senior author of the study and professor of pathology in The Ohio State University College of Medicine.

Tesla secures massive 1.6 GWh Megapack order for giant project

Posted by in categories: energy, sustainability

Tesla has secured a massive Megapack order for a new giant energy storage project that will likely become the largest in the world.

The project in question is the Melbourne Renewable Energy Hub (MREH), which is located just outside of Melbourne.

When completed, it will consist of three battery systems totaling 600 MW/1.6 GWh of capacity.

Harvesting more solar energy with two-dimensional supercrystals

Posted by in categories: chemistry, particle physics, solar power, sustainability

When Emiliano Cortés goes hunting for sunlight, he doesn’t use gigantic mirrors or sprawling solar farms. Quite the contrary, the professor of experimental physics and energy conversion at LMU dives into the nanocosmos.

“Where the high-energy particles of , the photons, meet atomic structures is where our research begins,” Cortés says. “We are working on material solutions to capture and use solar energy more efficiently.”

His findings have great potential as they enable novel solar cells and photocatalysts. The industry has high hopes for the latter because they can make accessible for chemical reactions—bypassing the need to generate electricity. But there is one major challenge to using sunlight, which solar cells also have to contend with, Cortés knows: “Sunlight arrives on Earth ‘diluted,’ so the energy per area is comparatively low.” Solar panels compensate for this by covering large areas.

Doroni’s all-electric flying car gets flight certified in the US

Posted by in categories: sustainability, transportation

Flying electric cars are not just for sci-fi movies. Miami-based Doroni Aerospace announced Friday its all-electric flying car, the Doroni H1, received official FAA Airworthiness Certification. And the best part – it’s designed to fit in your garage.

Doroni claims to be the first company to test manned flights with a 2-seater flying electric car in the US. The Doroni H1 took flight earlier this year.

CEO Doron Merdinger successfully piloted the personal electric vertical takeoff and landing aircraft (eVTOL) this summer. Merdinger said receiving the flight certification “is not just a milestone for our company, but a leap forward for the entire field of personal air mobility.”

Quantum computers could solve problems in minutes that would take today’s supercomputers millions of years

Posted by in categories: economics, health, quantum physics, supercomputing

“We’re looking at a race, a race between China, between IBM, Google, Microsoft, Honeywell,” Kaku said. “All the big boys are in this race to create a workable, operationally efficient quantum computer. Because the nation or company that does this will rule the world economy.”

It’s not just the economy quantum computing could impact. A quantum computer is set up at Cleveland Clinic, where Chief Research Officer Dr. Serpil Erzurum believes the technology could revolutionize the world of health care.

Quantum computers can potentially model the behavior of proteins, the molecules that regulate all life, Erzurum said. Proteins change their shape to change their function in ways that are too complex to follow, but quantum computing could change that understanding.
