University of Glasgow researchers lend support to major Martian meteorite study
Researchers from the School of Geographical & Earth Sciences have contributed to a new study ­of a Martian meteorite which could provide insights into the reactions that led to the building blocks of life on early Earth. The study, led by the Carnegie Institution for Science and , demonstrates that organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago.

Could acid-neutralising life-forms make habitable pockets in Venus' clouds?
Could acid-neutralising life-forms make habitable pockets in Venus’ clouds?
A new study shows it's theoretically possible. The hypothesis could be tested soon with proposed Venus-bound missions. If life is there, how does it propagate in an environment as dry as the clouds of Venus? Paul Rimmer It's hard to imagine a more inhospitable world than our closest planetary neighbour.

Precision sieving of gases through atomic pores in graphene
Precision sieving of gases through atomic pores in graphene
By crafting atomic-scale holes in atomically thin membranes, it should be possible to create molecular sieves for precise and efficient gas separation, including extraction of carbon dioxide from air, University of Manchester researchers have found. If a pore size in a membrane is comparable to the size of atoms and molecules, they can either pass through the membrane or be rejected, allowing separation of gases according to their molecular diameters.

Colour-changing magnifying glass gives clear view of infrared light
Colour-changing magnifying glass gives clear view of infrared light
By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing. It's like listening to slow-rippling earthquake waves by colliding them with a violin string to get a high whistle that's easy to hear, and without breaking the violin Jeremy Baumberg Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat at room temperature.

'Super jelly' can survive being run over by a car | University of Cambridge
’Super jelly’ can survive being run over by a car | University of Cambridge
Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it, and completely recover to its original shape, even though it's 80% water. At 80% water content, you'd think it would burst apart like a water balloon, but it doesn't: it stays intact and withstands huge compressive forces Oren Scherman The soft-yet-strong material, developed by a team at the , looks and feels like a squishy jelly, but acts like an ultra-hard, shatterproof glass when compressed, despite its high water content.

Electric vehicles could be powered by Hydrogen harvested from sewage
· Hydrogen is valuable as it is a renewable source, and could be sold to the chemicals and plastics industry or used in hydrogen fuel cells for energy storage or electric vehicles · The ability to take hydrogen from waste water provides a new economic and environmental opportunity, however until now it has been incredibly expensive to suffice · Using a recycled carbon fibre mat, researchers from WMG, University of Warwick, have been able to produce Hydrogen from wastewater for Severn Trent Wastewater treatment is vital to remove pathogens, but is incredibly energy intensive.

Researchers identify and clear efficiency hurdle for organic solar cells | University of Cambridge
Researchers identify and clear efficiency hurdle for organic solar cells | University of Cambridge
Researchers have identified a key mechanism responsible for the lower efficiencies of organic solar cells and shown a way that this hurdle might be overcome. Organic solar cells can do lots of things that inorganic solar cells can't, but their commercial development has plateaued in recent years, in part due to their inferior efficiency Alexander Gillett The researchers, led by the , identified a loss pathway in organic solar cells which makes them less efficient than silicon-based cells at converting sunlight into electricity.

Nano ’camera’ made using molecular glue allows real-time monitoring of chemical reactions
Researchers have made a tiny camera, held together with 'molecular glue' that allows them to observe chemical reactions in real time. This platform is a really big toolbox - it opens up lots of new possibilities for imaging chemical reactions Kamil Sokolowski The device, made by a team from the University of Cambridge, combines tiny semiconductor nanocrystals called quantum dots and gold nanoparticles using molecular glue called cucurbituril (CB).

Atomic snapshots show fast ion migration in ultra-thin clays
Research led by The University of Manchester has found that ions diffuse 10,000 times faster inside atomically thin clays than in bulk clay crystals. Clays are used in a wide variety of membrane applications, so this result offers the potential to achieve vastly improved desalination or fuel cell performance simply by switching to ultra-thin clays when producing the membranes.

Smartphone screens effective sensors for soil or water contamination
The touchscreen technology used in billions of smartphones and tablets could also be used as a powerful sensor, without the need for any modifications. Instead of interpreting a signal from your finger, what if we could get a touchscreen to read electrolytes, since these ions also interact with the electric fields? Ronan Daly Researchers from the University of Cambridge have demonstrated how a typical touchscreen could be used to identify common ionic contaminants in soil or drinking water by dropping liquid samples on the screen, the first time this has been achieved.
