A newly-developed magnetic soap could be used to minimize the environmental impact of oil ...

When oil gets spilled in a waterway, clean-up crews will often introduce a solution known as a surfactant. This is a detergent that lessens the surface tension between the water and the overlaying oil slick, causing the oil to form into individual droplets which then sink or get dispersed by wave action. Unfortunately, such detergents aren’t entirely environmentally-friendly themselves, so the use of them on oil spills has been criticized as simply replacing one pollutant with another. Now, however, scientists from the University of Bristol have created a magnetic soap, that could be removed from the water once it had done its job.  Read More

Researchers claim a newly discovered molecule found in the Earth’s atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.  Read More

A new type of stem-cell-seeded bandage, designed to heal torn meniscal cartilage such as  ...

Every year, approximately 1.7 million people in the U.S. and Europe tear a meniscus – children and athletes are especially prone to such injuries. But first, just what is a meniscus? It’s one of two pieces of cartilage located inside each knee, that provide a cushion between the tibia and the femur. While smaller tears can heal on their own, larger tears often require a partial or complete removal of the meniscus. Within several years, this can result in the early onset of osteoarthritis. Recently, a new type of stem cell-seeded bandage, developed at the University of Bristol, has been approved for a clinical trial on meniscal tears. It may greatly reduce the need for menisectomies.  Read More

Researchers at the University of Bristol have developed a seismological 'speed gun'

Researchers at the University of Bristol have developed a seismological "speed gun" which takes multiple seismic readings of single events to determine how quickly the Earth's mantle is moving. While the instruments used to measure this movement aren't hand-held or new to the field, the way that the data is interpreted is ground breaking.  Read More

The photonic chip next to a UK penny. The chip contains micrometer and sub-micrometer feat...

Research conducted at the University of Bristol means a number of quantum computing algorithms may soon be able to execute calculations of a complexity far beyond what today's computers allow us to do. The breakthrough involves the use of a specially designed optical chip to perform what's known as a "quantum walk" with two particles ... and it suggests the era of quantum computing may be approaching faster than the scientific establishment had predicted.  Read More

In news that might be a little worrying when coupled with our recent story of the flesh-eating robotic clock, UK researchers have developed a Chewing Robot. Thankfully the uses for the Chewing Robot are more benign - it has been developed to study the wear and tear on dental elements, such as fillings, crowns and bridges. By reproducing the motion and forces sustained by teeth within a human mouth, the robot has the potential to dramatically improve the process of developing and testing new dental materials.  Read More

Achieving quantum computing is not just a sheer matter of improving computational speed: it is a radically different paradigm that has attracted physicists and engineers for decades with its potential to solve problems across a number of domains — from database searches to prime number factorization and artificial intelligence. Now in a major breakthrough, a research team from the University of Bristol has achieved highly precise control of up to four photons on a silicon chip for the very first time.  Read More
