Crystal structures in super slow motion

Crystal structures in super slow motion

Laser beams are used to change the properties of materials in an extremely precise way. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they have so far eluded direct observation. Researchers have now managed to film, for the first time, the laser transformation of a crystal structure with nanometer resolution and in slow motion in an electron microscope. …read more

NSAIDs might exacerbate or suppress COVID-19 depending on timing, mouse study suggests

NSAIDs might exacerbate or suppress COVID-19 depending on timing, mouse study suggests

New research shows that non-steroidal anti-inflammatory drugs (NSAIDs) reduced both antibody and inflammatory responses to SARS-CoV-2 infection in mice. …read more

Squeezing a rock-star material could make it stable enough for solar cells

Squeezing a rock-star material could make it stable enough for solar cells

A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell. The required pressure is well within the reach of industrial manufacturing requirements. …read more

Designing customized ‘brains’ for robots

Researchers have developed an automated way to design customized hardware that speeds up a robot’s operation. The system, called robomorphic computing, accounts for the robot’s physical layout in suggesting an optimized hardware architecture. …read more

Spitting Cobra venom reveals how evolution often finds the same answer to a common problem

Spitting Cobra venom reveals how evolution often finds the same answer to a common problem

A study of spitting cobras reveals how a combination of venom components have evolved to create an instantly painful venom, not once, but on three separate occasions. …read more

A closer look at T cells reveals big differences in mild vs. severe COVID-19 cases

A closer look at T cells reveals big differences in mild vs. severe COVID-19 cases

How long does immunity to SARS-CoV-2 last following infection? Researchers have uncovered an interesting clue. Their new study suggests that people with severe COVID-19 cases may be left with more of the protective ‘memory’ T cells needed to fight reinfection. …read more

New starfish-like fossil reveals evolution in action

Researchers have discovered a fossil of the earliest starfish-like animal, which helps us understand the origins of the nimble-armed creature. …read more

Hematopoietic stem cell transplants may provide long-term benefit for people with MS

Hematopoietic stem cell transplants may provide long-term benefit for people with MS

A new study shows that intense immunosuppression followed by a hematopoietic stem cell transplant may prevent disability associated with multiple sclerosis (MS) from getting worse in 71% of people with relapsing-remitting MS for up to 10 years after the treatment. The study also found that in some people their disability improved over 10 years after treatment. …read more
