WEHI researchers have discovered a key differentiation process that provides an essential immune function in helping to control cancer and infectious diseases.

The research, published in Science Immunology, is the first to show a new factor — DC-SCRIPT — is required for the function a particular type of dendritic cell — called cDC1 — that is essential in controlling the immune response to infection.

Led by WEHI Professor Stephen Nutt, Dr Michael Chopin and Mr Shengbo Zhang, it defines the role for a new regulatory protein in producing dendritic cells...

New Batteries give Jolt to Renewables, Energy Storage

This magnified image shows aluminum deposited on carbon fibers in a battery electrode. The chemical bond makes the electrode thicker and its kinetics faster, resulting in a rechargeable battery that is safer, less expensive and more sustainable than lithium-ion batteries.

Researchers have been exploring the use of low-cost materials to create rechargeable batteries that will make energy storage more affordable. Now, they have shown that a new technique incorporating aluminum results in rechargeable batteries that offer up to 10,000 error-free cycles.

The cost of harvesting solar energy has dropped so much in recent years that it’s giving traditional energy sources a run for their money...

New study ties Solar Variability to the onset of decadal La Nina events

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

If the connection outlined in the journal Earth and Space Science holds up, it could significantly improve the predictability of the largest El Nino and La Nina events, which have a number of seasonal climate effects over land. For example, the southern United States tends to be warmer and drier during a La Nina, while the northern U.S. tends to be colder and wetter.

“Energy from the Sun is the major driver of our entire Earth system and makes life on Earth possible,” said Scott McIntosh, a scientist at the National Center for Atmosp...

Telehealth has become a critical way for doctors to still provide health care while minimizing in-person contact during COVID-19. But with phone or Zoom appointments, it’s harder for doctors to get important vital signs from a patient, such as their pulse or respiration rate, in real time.

A University of Washington-led team has developed a method that uses the camera on a person’s smartphone or computer to take their pulse and respiration signal from a real-time video of their face...
