Molecular oxygen sensing systems conserved across kingdoms

A biochemical oxygen sensor conserved across biological kingdoms allows both plant and animal cells to sense changes in oxygen levels. The newly identified enzymatic oxygen sensor is functionally identical in plants and animals, with potential implications for addressing cellular hypoxia in human diseases like cancer.

Strain of common cold virus could revolutionize treatment of bladder cancer

A study found that a naturally occurring strain of the common cold, coxsackievirus CVA21, can target and destroy bladder cancer cells without causing harm to healthy cells. The treatment showed significant reduction in tumour burden and removal of disease in one patient after just one week.

Scientists discover the biggest seaweed bloom in the world

The team discovered that the belt forms seasonally in response to two key nutrient inputs: human-derived from Amazon River discharge and natural from West African upwelling. The blooms are expected to be a new normal, with data indicating a possible regime shift since 2011.

The global tree restoration potential

A new study by the Crowther Lab suggests that global forest restoration could capture two-thirds of human-made carbon emissions. The study found that there is potential to increase the world's forest land by a third without affecting cities or agriculture, with forests capable of storing 205 billion tonnes of carbon once mature.

How trees could save the climate

A new study by ETH Zurich reveals that reforestation efforts could store two-thirds of the 300 billion tonnes of carbon released into the atmosphere since the Industrial Revolution. The greatest potential for forest restoration lies in six countries: Russia, US, Canada, Australia, Brazil, and China.

The Lancet: Nerve transfer surgery restores hand function and elbow extension in 13 young adults with complete paralysis

A novel surgical technique connects functioning nerves with injured nerves to restore power in paralyzed muscles, enabling participants to perform everyday tasks independently. The study suggests that nerve transfers can achieve similar functional improvements to traditional tendon transfers, with the benefit of smaller incisions and s...
