New research published Feb. 2 in the Journal of the American Medical Association found that older adults with a major risk gene for Alzheimer’s disease known as APOEÉ›4 who ate at least one seafood serving per week showed fewer signs of Alzheimer’s-related brain changes.  In contrast, this association was not found in the brains of volunteers who ate fish weekly but did not carry the risk gene.   

Air pollution from vehicles is killing tens of thousands of people every year in the UK alone, write Jean Lambert, Molly Scott Cato & Keith Taylor, an outrage set into stark focus by VW's 'test cheating'. The EU's response? To relax tests and allow cars to be more polluting - with the full support of the UK government.

Rather than clamping down on the car industry's irresponsible approach to pollution, EU governments and the Commission instead want to rewrite existing law, providing loopholes which will allow cars to legally pollute more.

Faced with a public health crisis, responsible for nearly half a million premature deaths in Europe each year, we would expect an emergency response.

Human blood cells have olfactory receptors that respond to Sandalore. This could provide a starting point for new leukaemia therapies, as researchers from Bochum report in a current study.

Olfactory receptors exist not only in the nose, but also in many other parts of the body, including the liver, the prostate and the intestines. Researchers headed by Prof Dr Dr Dr Hanns Hatt from the Ruhr-Universität Bochum have now demonstrated them in white blood cells in humans.

Together with colleagues from the Essen University Hospital, the Bochum-based group identified the receptor OR2AT4 in a cultivated cell line, taken from patients suffering from chronic myelogenous leukaemia. The researchers identified the same receptor in white blood cells isolated from blood freshly obtained from patients suffering from acute myeloid leukaemia. It is activated by Sandalore, a synthetic odorant with a sandalwood note.

The mosquito-borne Zika virus has been linked to a surge in cases of birth defects in Brazil, and is spreading in other countries in the southern hemisphere. Flaminia Catteruccia, associate professor of immunology and infectious diseases at Harvard T.H. Chan School of Public Health, says the virus may have adapted to the human environment and mutated.

The overconsumption of meat will inevitably push global temperatures to dangerous levels, a recent study has warned, urging reluctant governments to take action.

The world's rapidly expanding population is posing a huge challenge to farmers. A reportpublished in November 2015 by Chatham House, and the Glasgow University Media Group, examined the interconnection between meat and dairy consumption with climate change.

Nearly one-third of the world's cultivated land is being used to grow animal feed. In the EU alone, 45% of wheat production is used for this purpose, with 30% of overall use met by imports.

A new global analysis of seafood found that fish populations throughout the world's oceans are contaminated with industrial and agricultural pollutants, collectively known as persistent organic pollutants (POPs). The study from researchers at Scripps Institution of Oceanography at UC San Diego also uncovered some good news?concentrations of these pollutants have been consistently dropping over the last 30 years.

Flint, Michigan temporarily switched its water supply from Lake Huron to the Flint River in April 2014 to cut costs. Should officials have known that lead contamination would result?

Many people will see the snow currently blanketing much of the U.S. Eastern Seaboard as a nuisance coating sidewalks and roads. Others are celebrating it as an excuse to spend the day swooshing down a hill.

As for me, I like to think of snow as food.

Growing up in Missouri, I consumed as much snow ice cream as possible from November to March. Each time the winter sky let loose, I caught a bowl of fresh flakes. My grandmother mixed raw eggs, cream and sugar and poured it over top.

Snow is one of the first "wild" foods small humans learn to forage. And this time of year it's both free and plentiful to many.

Meals consumed at fast-food restaurants are often seen as one of the biggest contributors to the obesity epidemic. But according to a new study in the Journal of the American Academy of Nutrition and Dietetics, 92 percent of 364 measured restaurant meals from both large-chain and non-chain (local) restaurants exceeded recommended calorie requirements for a single meal. In 123 restaurants in three cities across America, the research team found that a single meal serving, without beverages, appetizers, or desserts sometimes exceeded the caloric requirements for an entire day.

Burning down forests in Africa and South-East Asia causes ozone pollution in the air as far as the western Pacific Ocean, researchers say, calling for revision of global climate models to reflect their findings.

In a paper published in Nature Communications last week (13 January), the scientists say their data contradicts earlier theories on the origins of ozone-rich air parcels above the tropical western Pacific, which were thought to descend naturally from a higher atmospheric layer.
