Microsatellite swarms could paint clearer picture of our planet

Microsatellites such as those developed by ICEYE not only reduce the size of the satellite but also cut costs significantly.

by Gareth Willmer Tiny, low-cost satellites that can work together to boost their output and a technology that reduces the loss of satellite data are two of the latest innovations to hit the Earth observation market – and the results promise to reveal a more detailed image of our planet. Space is not just a … Read more

Healthy competition intensifies 30-year quest for HIV vaccine

If the research teams manage to reproduce a response that produces antibodies against all strains of HIV, they could create a universal vaccine.

by Frieda Klotz In 1984, after HIV was identified as the cause of AIDS, the US secretary of health, Margaret Heckler, declared a vaccine would be found within two years. Reports of a mysterious virus predominantly affecting gay men had been growing across the US and, with awareness rising, the World Health Organization had held … Read more

Earth observations show Europe’s natural wealth in steep decline

Satellite data can show environmental shifts in protected areas like the Camargue wetlands, where rising sea levels have a damaging impact.

by Frieda Klotz In March 2018, French scientists reported a steep decline in the country’s bird populations, primarily as a result of agricultural activity. Causes include the increase in monoculture, detrimental land-use policies and, perhaps most importantly, the growth in the use of powerful pesticides such as neonicotinoids, which, by killing off insects, reduces the bird … Read more

Eco detergents – for greener whites in the airing cupboard

Giving enzymes in detergents and fabric softeners a microencapsulation can make them reusable.

by Rob Coppinger ‘Clean’ and ‘soft’ are words strongly associated with washing products and fabric softeners, and soon they are set to be described as ‘green’ too with less chemical waste and longer-lasting action. Of all modern conveniences, the humble washing machine is perhaps the greatest labour-saving device. Hours of dunking, scrubbing and wringing wet … Read more

Sticky tape and simulations help assess microplastic risk

Microplastics are considered the most common form of marine litter.

by Natalie Grover Tiny pieces of plastic, now ubiquitous in the marine environment, have long been a cause of concern for their ability to absorb toxic substances and potentially penetrate the food chain. Now scientists are beginning to understand the level of threat posed to life, by gauging the extent of marine accumulation and tracking … Read more

Electric ferries and joined-up shipping to turn sea travel green

Digital communication between ships could help optimise shipping routes and reduce fuel consumption.

Electric ferries and digital communication between ships could help in the quest to decarbonise maritime transport, a sector which is often perceived as being the green option but could still do much to lower its environmental footprint. The global shipping industry currently emits around 1000 million tonnes of CO2 into the atmosphere each year, but according to … Read more
