Chemical mixtures pose ‘underestimated’ risk to human health say scientists

and the health risks of this are not yet fully understood.

Each of us harbours hundreds of man-made chemicals inside our bodies because we are exposed to them in our daily lives. While individual chemicals may not be of immediate concern to public health, scientists now worry that certain mixtures of them may pose previously underestimated risks to health. This year, the European Union heavily restricted … Read more

Gravitational waves helping to expose black holes, dark matter and theoretical particles

Gravitational waves – the invisible ripples in the fabric of space predicted by Albert Einstein – are opening up a new era of astronomy that is allowing scientists to see parts of the universe once thought to be invisible, such as black holes, dark matter and theoretical subatomic particles called axions. Almost 100 years after … Read more

How scientists are piecing together the history of the moon

ANDY SMITH ASTRONOMY

In the solar system’s early days, a first Earth is thought to have been pulverised by a planet that scientists call Theia. We don’t know what it was made of or where it came from, only that it may have been the size of Mars. The powerful collision destroyed both planets so completely that scientists … Read more

Understanding immune system switches will spark new drugs

Identifying the chemical switches that turn different parts of our immune system on and off is opening up new avenues for treating diseases such as Parkinson’s, Alzheimer’s, cancer and rheumatoid arthritis – and potential new uses for discarded drugs, according to Professor Luke O’Neill, an immunologist at Trinity College Dublin, Ireland. Your work focuses on … Read more

Waste CO2 to be turned into ingredients for fuel, plastics and even food

Scientists are ramping up efforts to turn waste CO2 from industry into chemicals such as methanol in a bid to reduce emissions and provide a new source of raw materials for use in fuel, cement and food production. It’s part of a strategy to halt global warming by cutting down the amount of CO2 we … Read more

System to rid space station of astronaut exhalations inspires Earth-based CO2 removal

When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere? In order to limit global warming to 1.5˚C above pre-industrial levels and avoid some of the worse impacts of climate change, it … Read more
