New research reveals how hurricane Lane brought fire and rain to Hawaiian islands

A recent study reveals that Hurricane Lane's extreme weather conditions, combining heavy rainfall and fire hazards, exacerbated the storm's impact on the Hawaiian Islands. The research highlights the importance of considering both environmental and socioeconomic factors in assessing population vulnerability to natural hazards.

Gum disease may raise risk of some cancers

A study published in the journal Gut found that people with periodontal disease may be at a higher risk of developing oesophageal and gastric cancer. The research examined data from over 98,000 women and men and found a 43-52% increased risk associated with periodontal disease.

How to repair your gut

A strong cellular lining is essential for a healthy gut, and damage to it can cause painful symptoms. Monash University researchers have identified a key biomolecule, Neuregulin-1, that accelerates the repair of damaged tissue by prompting stem cells to regenerate.

Concerns over police head injuries

A new study found that police officers are at a higher risk of traumatic brain injuries (TBI) than the general public, with 38.9% reporting a TBI resulting in loss of consciousness. Officers with a history of TBI also experienced higher levels of post-concussion symptoms and mental health issues, including depression and PTSD.

Could mini-Neptunes be irradiated ocean planets?

New findings suggest mini-Neptunes may form as super-Earths with a rocky core surrounded by water in a supercritical state, challenging their previous classification as gas planets. Scientists propose that intense stellar irradiation causes a greenhouse effect, increasing the size of atmospheres and forming such planetary configurations.

COVID-19 replicating RNA vaccine has robust response in nonhuman primates

A replicating RNA vaccine has shown robust immune response in both young and old animal models, producing antibodies comparable to those in people recovering from COVID-19. The vaccine's design avoids immune responses that could exacerbate the virus, instead inducing protective antiviral measures and T cells.

Plato was right. Earth is made, on average, of cubes

According to the study published in the Proceedings of the National Academy of Sciences, rocks on Earth are, on average, cube-shaped due to fragmentation processes. The researchers' findings suggest that this shape is statistically average and applies not only to Earth but also around the solar system.

Signal transduction in cells: Precise or economical?

Researchers at Max-Planck Institute for Terrestrial Microbiology study signal transmission in baker's yeast to understand how cells balance information accuracy with energy costs. They found that the pheromone signalling pathway contains negative feedback regulations that improve accuracy, but may also impose fitness costs.
