Blood clotting research holds hope for sepsis

Researchers from the University of Birmingham identified a novel mechanism for platelet activation in pathogenic blood clotting. The mechanism, involving platelet receptor glycoprotein I alpha (GPIbα) and anti-microbial protein S100A8/A9, is not blocked by classical anti-platelet drugs and accelerates fibrin activation and thrombosis.

Good vibrations turbo charge green hydrogen production

Engineers at RMIT University have developed a method to boost green hydrogen production through electrolysis by up to 14 times using high-frequency vibrations. This innovation tackles the high cost of electrode materials and eliminates the need for corrosive electrolytes, making it cheaper and more efficient.

Scientists reveal controlling factors of water and heat exchanges over the Zoige wetland

Researchers investigated hydrometeorological factors in alpine wetlands during warm and cold seasons. They found that depth of frozen soil averages 20-40 cm, with sensible heat flux greater before solar noon in the cold season. Temperature and longwave radiation are key control factors for heat exchange.

A double bind for cancer

Researchers found that simultaneously targeting two signalling switches can severely inhibit tumour angiogenesis, cancer growth and metastasis in multiple models of cancer. This approach has the potential to restrict a cancer's ability to escape therapy by rapidly destroying the VEGF receptor when both receptors are targeted.

Alzheimer’s progression in Down syndrome appears similar to other genetic, early onset forms of the disease

A study funded by NIH found that people with Down syndrome have a similar level of amyloid plaques in their brains as those with hereditary, early-onset Alzheimer's. This suggests that individuals with both conditions may benefit from participating in studies on Alzheimer's therapies aimed at slowing amyloid plaque formation.
