Predicting seismic activity at fracking sites to prevent earthquakes
Predicting seismic activity at fracking sites to prevent earthquakes
Scientists from the University of Bristol have found a more effective way to predict seismic activity at hydraulic fracturing sites, ensuring that potential earthquake activity remains within safe levels. Hydraulic fracturing, or fracking, is a technique designed to recover gas and oil from shale rock by drilling down into the earth and injecting a mixture of water and sand at high-pressure, creating fractures that allow the gas or oil to flow out.

High blood sugar levels and BMI linked to stillbirth in mothers with diabetes
High maternal blood sugar levels and BMI are risk factors for stillbirth in mothers with diabetes, according to a new study in Diabetologia (the journal of the European Association for the Study of Diabetes), with babies at the lowest and highest weights being most at risk. Mothers with pre-pregnancy diabetes are at a four to five times increased risk of stillbirth - with no improvement seen over recent years, in contrast with decreasing stillbirth rates seen in the general obstetric population.

Strange bacteria hint at ancient origin of photosynthesis
Structures inside rare bacteria are similar to those that power photosynthesis in plants today, suggesting the process is older than assumed. The finding could mean the evolution of photosynthesis needs a rethink, turning traditional ideas on their head. We're beginning to see that much of the established story about the evolution of photosynthesis is not supported by the real data Dr Tanai Cardona Photosynthesis is the ability to use the Sun's energy to produce sugars via chemical reactions.

Supercomputers use graphics processors to solve longstanding turbulence question
Supercomputers use graphics processors to solve longstanding turbulence question
Advanced simulations have solved a problem in turbulent fluid flow that could lead to more efficient turbines and engines. When a fluid, such as water or air, flows fast enough, it will experience turbulence - seemingly random changes in velocity and pressure within the fluid. From my first days studying fluid mechanics I had some fundamental questions that I wanted to know the answers to.

Anonymising personal data ’not enough to protect privacy’, shows new study
Current methods for anonymising data leave individuals at risk of being re-identified, according to new UCLouvain and Imperial research. Companies and governments downplay the risk of re-identification by arguing that the datasets they sell are always incomplete. Our findings show this might not help.
