Dino-killing asteroid sped up bird evolution
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study just published in  Systematic Biology. Dr Daniel Field from the Milner Centre for Evolution at the University of Bath and Cornell PhD candidate Jacob Berv suggest that the meteor-induced mass extinction (a.k.a.

Sexually aroused male flies unable to sleep after close encounters with females
The urge to mate appears to override the need to sleep in flies, according to new research that hints at the importance of sleep for animals. The result suggests that there are some situations where flies and other animals can eliminate the drive to sleep entirely, rather than put it off until later.

Self-assembling nanoparticle arrays can switch between a mirror and a window
By finely tuning the distance between nanoparticles in a single layer, researchers have made a filter that can change between a mirror and a window. The development could help scientists create special materials whose optical properties can be changed in real time. These materials could then be used for applications from tuneable optical filters to miniature chemical sensors.

Scientists make methanol using air around us
Scientists at Cardiff University have created methanol from methane using oxygen from the air. Methanol is currently produced by breaking down natural gas at high temperatures into hydrogen gas and carbon monoxide before reassembling them - expensive and energy-intensive processes known as 'steam reforming' and 'methanol synthesis.' But researchers at Cardiff Catalysis Institute have discovered they can produce methanol from methane through simple catalysis that allows methanol production at low temperatures using oxygen and hydrogen peroxide.

Can the UK’s gas grid go green? New white paper explores options
Options for a greener gas grid are explored by researchers from Imperial College London in a white paper out today. The gas grid or network currently transports natural gas to industries, households and businesses. Due to concerns over greenhouse gas emissions, scientific scenarios to tackle climate change show a reduced role for gas networks in the future, with policymakers preferring routes that involve decarbonised electricity.

Physicists squeeze extra data from superfast x-ray probes using machine learning
Chemical reactions could be probed in even greater detail using a method invented by Imperial researchers that better characterises ultrafast x-rays. X-rays can be used to investigate the structures of, and reactions between, molecules on very small scales and at high speed. To do this, scientists use free electron lasers (FELs) to create a train of x-ray pulses.

Himalayan powerhouses: how Sherpas have evolved superhuman energy efficiency
Sherpas have evolved to become superhuman mountain climbers, extremely efficient at producing the energy to power their bodies even when oxygen is scarce, suggests new research published today in the Proceedings of National Academy of Sciences (PNAS) . Sherpas have spent thousands of years living at high altitudes, so it should be unsurprising that they have adapted to become more efficient at using oxygen and generating energy Andrew Murray The findings could help scientists develop new ways of treating hypoxia - lack of oxygen - in patients.

New breakthrough makes it easier to turn old coffee waste into cleaner biofuels
A new process has the potential to enable 720,000 tonnes of biodiesel to be produced each year from spent coffee grounds Future Americano, cappuccino and latte drinkers could help produce the raw material for a greener biofuel that would reduce our reliance on diesel from fossil fuels. Purpose-grown feedstocks (used to extract oils) for biodiesels are controversial because of their cost and the demand they place on land and water.

Next-gen solar cells could be improved by atomic-scale redesign
Researchers have uncovered the exact mechanism that causes new solar cells to break down in air, paving the way for a solution. Solar cells harness energy from the Sun and provide an alternative to non-renewable energy sources like fossil fuels. However, they face challenges from costly manufacturing processes and poor efficiency - the amount of sunlight converted to useable energy.
