People picturing positive experiences found to produce more antibodies, hinting at future clinical potential
Positive thoughts may boost the immune system according to research that points to a connection between the mind and our body’s natural defences.
Scientists have found people who used positive thinking to boost activity in the brain’s reward system responded better to vaccination, with their immune systems producing more antibodies than others after having the shot.

Brown Swiss in Austria has been discovered using tools in different ways – something only ever seen in humans and chimpanzees
Scientists have been forced to rethink the intelligence of cattle after an Austrian cow named Veronika displayed an impressive – and until now undocumented – knack for tool use.
Witgar Wiegele, an organic farmer and baker from a small town in Carinthia near the Italian border, keeps Veronika as a pet and noticed that she occasionally played with sticks and used them to scratch her body.

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.

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.
