RemoveDebris: UK satellite nets 'space junk' Media playback is unsupported on your device A British satellite has successfully deployed a net in orbit to demonstrate how to capture space debris.

The event took place more than 300km above the Earth. It was part of a series of trials that will showcase different technologies to remove the redundant hardware now circling the Earth. Some 7,500 tonnes is said to be drifting aimlessly overhead, posing a collision hazard to operational missions. The aptly named RemoveDebris satellite took a video of its net experiment.

Suddenly, a bright web, fired from the satellite, comes into view. Air pollution linked to much greater risk of dementia. Air pollution may increase the chance of developing dementia, a study has suggested, in fresh evidence that the health of people of all ages is at risk from breathing dirty air.

People over 50 in areas with the highest levels of nitrogen oxide in the air showed a 40% greater risk of developing dementia than those with the least NOx pollution, according to the research, based on data from London. The observational study, published in the BMJ Open journal on Wednesday, cannot establish that air pollution was a direct cause of the dementia cases. However, the authors said the link between higher pollution and higher levels of dementia diagnosis could not be explained by other factors known to raise risks of the disease. Air pollution has already been linked with cardiovascular and respiratory disease, but this is one of the first studies to examine links with neurodegenerative illness. The new findings add to a growing body of recent research on the wide-ranging effects of air pollution. Strawberry needle scare: Australia probe as 'vicious crime' widens.

Image copyright JOSHUA GANE Australia has ordered an investigation into the discovery of sewing needles hidden in strawberries, amid growing alarm over scares across the country.

Contaminated punnets have now been reported in six states and territories. A minister called it a "vicious crime". One man was taken to hospital after eating a strawberry that held a needle. Several brands have been recalled, while New Zealand's biggest grocers have stopped selling Australian strawberries as a precaution. Australian Health Minister Greg Hunt ordered the Food Safety Authority of Australia and New Zealand to investigate the scare. 'Climate change moving faster than we are,' says UN Secretary General.

UK researchers also found that insects in northern latitudes were more vulnerable than their southern-dwelling cousins. The team added that many insects were unable to move great distances while they are juveniles. Therefore, they are at risk from a warming climate. The findings have been published in the Journal of Evolutionary Biology. "You get an extreme heat weather event that [the insect] cannot escape from because they are juveniles, so they can't move as much," explained co-author Rhonda Snook from the University of Sheffield, UK.

UK car sales at record high in 2016 [05/01/17] Image copyright PA The number of new cars sold in the UK hit an all-time high in 2016.

The Society of Motor Manufacturers and Traders (SMMT), said 2.69 million cars were registered last year, 2% higher than in 2015. The industry body said 2016's growth was due to "very strong" consumer confidence, low-interest finance deals and the launch of several new models. However, the SMMT says this year is unlikely to set another record, with sales expected to fall by 5-6%. SMMT chief executive Mike Hawes said such a fall would not represent "a collapse in the market" and sales would still be at "historically an incredibly high level". Have baby boomers stolen the family silver? Image copyright Ian Wells We take it for granted that our children will be better off than us but the so-called millennials - anyone born in the 1980s or 1990s - could become the first generation to earn less than their parents.

And are those parents, mostly baby boomers who benefited from economic good times, tax cuts and free higher education to blame? The figures Baby boomers, people born between 1946 and 1965, will on average earn £740,000 during their lives, according to the Resolution Foundation. Generation X, those now aged between 35 and 50, are projected to earn 21% more than that - £835,000 on average. But the figure for millennials, the under-35s, is lower - they're forecast to earn £825,000 over their working lives. 'Stagnation Generation' Laura Gardiner, author of the Resolution Foundation's report Stagnation Generation found a range of reasons for the dismal outlook for millennials. Claudia also faces other financial burdens compared with her baby boomer father Ian.
