A bloom of bioluminescent phytoplankton has dazzled San Diego residents as the abundance of the algae along the coats lights up the water.The bloom was cause by a red tide, resulting in a higher level than normal of the plankton in the water. When the small organisms are disturbed, they let off light, making them more visible.

We now use 14,000 of the handy cloths every second - but they are increasingly clogging rivers and putting wildlife at risk. So how can we wean ourselves off them?

This week’s edition of the Upside looks at how the world can conserve water despite climate change, and how seeds planted in a Yorkshire valley have grown a global movementOne of the obvious consequences of climate change is that our reservoirs of fresh water are running out. As global temperatures continue to rise, people around the globe will have to figure out how to manage with less water.This week we looked at how one city united to tackle its water crisis, and found other tales of people coming together and turning around bleak situations.

Nuclear regulator prosecutes waste firm after injury leaves employee open to exposure

In my job, I have been stung countless times. But nothing comes close to the pain bullet ants inflictI carried out my first experiment with a stinging insect when I was seven, picking a honey bee off a dandelion and placing it on the arm of my teacher. My hypothesis was that it might sting her, and it turned out to be correct, much to her dismay.Where I grew up, in the Appalachian area of the north-east US, we had lots of honey bees and wasps of various sorts. As a kid, I was stung by virtually all of them. I realised that they registered the same sort of pain – the intensity may vary from one to the next, but they were fairly similar. But an accidental run-in with a colony of harvester ants led to a life-changing revelation: they didn’t feel at all as I expected they would. They really hurt. Continue reading...

From pop-up bike lanes to painted potholes, here are the imaginative ways frustrated cyclists are taking action to create a safer environmentAcross the world, transport planning and infrastructure tends to favour the car, and facilities for cyclists and pedestrians are an afterthought. In response, frustrated urban cyclists have thrown caution to the wind and written their own will into the fabric of the city, overturning the dominance of the car and creating a safer environment for cycling in imaginative ways.Cycling has the power to turn individuals into a community and communities have the power to improve our cities. These examples show how activism can be a real solution to urban problems. Continue reading...

Prosecution seen as key test of Queensland’s ability to hold mining companies to account

Vatican meeting between the climate-change skeptics in 2017 looked at setting up two-sided ‘debate’ about global warmingCardinal George Pell discussed a plan to set up a two-sided “debate” about human-caused climate change with the US Environmental Protection Agency chief, Scott Pruitt , at the Vatican in 2017, it has been revealed.According to documents collated by The New York Times, Pruitt joined Pell and others for a $240-a-head dinner in June 2017, an engagement that was left off official schedules of Pruitt’s Vatican visit.

Scientists tested nine different masks bought from Beijing, with variable resultsWe are all familiar with images of Beijing citizens wearing masks, but do they work? Scientists from Edinburgh’s Institute for Occupational Medicine tested nine different masks bought from Beijing shops. Generally, the filter in each mask worked well, the best stopped over 99% of the particle pollution and the worst stopped 70% to 80%. Next, volunteers wore the masks in a test chamber filled with diesel exhaust. Pollution inside the mask was measured as they walked, nodded and talked. One mask stopped 90% of the particle pollution while others offered almost no protection. The tightness of fit was crucial. Facial hair prevents a good seal and the fit also depends on the shape of the user’s face. If it fits well then breathing through a mask is not easy. Wearing a mask could therefore pose problems for people who already have breathing or heart difficulties. So, face masks are not the answer to our problems. Walking alongside quiet instead of busy roads can help, and generally you will experience less pollution if you walk or cycle rather than sit in a car, but the best route to clean air is not masks. We need reduce the pollution in our cities. Continue reading...

Sandy, Bedfordshire: I lean forward and the skater darts away in a series of fitful starts. A water measurer beneath my gaze stays put at the pond’s edgeA pond skater’s feet feel prey landing on the drumskin-tight surface of the water. Just how can this skater skate on thin “ice” while a fly the size of its eye falls through? Though the fly tries to drag its legs free, surface tension binds it to a sheet of elastic glue.I lean forward and the skater darts away in a series of fitful starts. A water measurer beneath my gaze stays put at the pond’s edge. An aquatic stick insect, Hydrometra stagnorum could easily be mistaken for a strand of dark human hair. My eyes are just a handspan away, so I can observe the detail of alternating light and dark strips along its abdomen, which remind me of a ruler. However, it gets its name from the way it walks over the surface with a measured tread. Continue reading...

Wenlock Edge, Shropshire: These delicate flowers are the colour of the far blue yonder, blue remembered hills, into the blue, the beyond, a spiritual eternity“Is love so prone to change and rot/ We are fain to rear forget-me-not/ By measure in a garden plot?” asked Christina Rossetti (A Bed of Forget-Me-Nots, 1856). The flowers of forget-me-not, Myosotis, may have been reared by measure in a garden plot here, before it was abandoned a hundred years ago and a wood of change, rot and indeed love took over.Water, creeping, pale, tufted, Jersey, wood, alpine, field, changing and early … forget-me-nots are species of Myosotis belonging to the borage family, famous for their blue flowers; the delicate pale blue of forget-me-not is unique. Some flowers on this plant growing along the path are a brilliant white, too. Continue reading...

After nearly becoming extinct in Britain, the cirl bunting has bounced back, thanks to joint efforts by RSPB and farmersFew British birds have enjoyed such mixed fortunes as the cirl bunting, Emberiza cirlus. Discovered by my ornithological hero George Montagu in 1800, near his Devon home, it extended its range across much of southern Britain, before going into sharp retreat in the 1970s.By 1989 there were just 120 pairs – all but two in south Devon. Then, thanks to the RSPB, and especially project officer Cath Jeffs, it bounced back. Jeffs persuaded local farmers to create the right habitat for the buntings, and today there are more than 1,000 breeding pairs. Continue reading...
