Study links rapid growth of ocean macroalgae to global heating and nutrient pollution

Scientists have warned of a potential “regime shift” in the oceans, as the rapid growth of huge mats of seaweed appears to be driven by global heating and excessive enrichment of waters from farming runoff and other pollutants.

Over the past two decades, seaweed blooms have expanded by a staggering 13.4% a year in the tropical Atlantic and western Pacific, with the most dramatic increases occurring after 2008, according to researchers at the University of South Florida.

Higher surface roughness of polythene cups may account for greater microplastic shedding, scientists say

Or will they have you in pieces?

Today’s puzzles are all geometrical, and all from the mind of the UK’s most enduring and eloquent popular maths writer, Ian Stewart.

Errors in measuring microplastic pollution can be corrected. Public trust in science also needs to be shored up

It is true that science is self-correcting. Over the long term this means that we can generally trust its results – but up close, correction can be a messy process. The Guardian reported last week that 20 recent studies measuring the amount of micro- and nanoplastics in the human body have been criticised in the scientific literature for methodological issues, calling their results into question. In one sense this is the usual process playing out as it should. However, the scale of the potential error – one scientist estimates that half the high-impact papers in the field are affected – suggests a systemic problem that should have been prevented.

The risk is that in a febrile political atmosphere in which trust in science is being actively eroded on issues from climate change to vaccinations, even minor scientific conflicts can be used to sow further doubt. Given that there is immense public and media interest in plastic pollution, it is unfortunate that scientists working in this area did not show more caution.

Exclusive: DNA test means patients could be offered most effective treatment first, boosting their chances of beating the disease

Scientists have developed a simple DNA blood test that can predict how well patients with breast cancer will respond to treatment.

More than 2 million people globally each year are diagnosed with the disease, which is the world’s most prevalent cancer. Although treatments have improved in recent decades, it is not easy to know which ones will work best for which patients.
