The design of an 'AND gate' created by Imperial College London scientists using E-Coli bac...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a computer - logic gates. Using DNA and harmless gut bacteria, the scientists have built what they claim are the most advanced biological logic gates ever created by scientists. The research could lead to the development of a new generation of microscopic biological computing devices that, amongst other things, could travel around the body cleaning arteries and destroying cancers.  Read More

Efforts to create a working "invisibility cloak" have generally involved the use of artificial materials with a negative refractive index known as metamaterials. Another promising technique involves the use of a natural crystal called calcite that boasts an optical property known as birefringence, or double-refraction. While both methods have proven successful in rendering very small objects invisible in specific wavelengths of light by bending and channeling light around them, both techniques require the "cloak" to be orders of magnitude larger than the object being concealed. Researchers are now reporting progress in overcoming this size limitation using a technology known as a "carpet cloak."  Read More

Psammaplin A is a naturally occurring chemical found in the sea sponge that has been found to block several components that are involved in the growth and division of cancer cells. Dr Matthew Fucher and his team at Imperial College London have developed a new, and inexpensive way of manufacturing psammaplin A, and is using synthetic variations of the chemical to better understand its anti-cancer properties, which will help them in future efforts to create anti-cancer drugs.  Read More

Slices of a Fano variety

Mathematicians are creating their own version of the periodic table that will provide a vast directory of all the possible shapes in the universe across three, four and five dimensions, linking shapes together in the same way as the periodic table links groups of chemical elements. The three-year project, announced today, should provide a resource that mathematicians, physicists and other scientists can use for calculations and research in a range of areas, including computer vision, number theory, and theoretical physics. For some mental exercise, check out these animations that have already been analyzed in the project.  Read More

The quest to build a working “invisibility cloak” generally focuses on the use of metamaterials – artificially engineered materials with a negative refractive index that have already been used to render microscopic objects invisible in specific wavelengths of light. Now, using naturally occurring crystals rather than metamaterials, two research teams working independently have demonstrated technology that can cloak larger objects in the broad range of wavelengths visible to the human eye.  Read More

Should cholesterol reducing drugs be served with fast food? (Photo: Suat Eman via freedigi...

A study from researchers at Imperial College London seriously suggests that it may be wise for fast food outlets to provide statin drugs free of charge with the condiments, so that customers can neutralize the heart disease dangers of fatty food. Statins are a class of drugs that can reduce the amount of "LDL" cholesterol in the blood. Some data suggests that this reduction is accompanied by a reduced risk of cardiovascular disease including heart attack and stroke.  Read More

Sequencing an entire genome is currently a highly complex, time-consuming process – the DNA must be broken down into segments and replicated, utilizing chemicals that destroy the original sample. Scientists from Imperial College London, however, have just announced the development of a prototype device that could lead to technology capable of sequencing a human genome within minutes, at a cost of just a few dollars. By contrast, when sequencing of the genome of Dr. James Watson (co-discoverer of the structure of DNA) was completed in 2007, it had taken two years and cost US$1 million.  Read More

Scientists have determined that it's theoretically  possible to create a spacetime cloak t...

Take some light bending metamaterials, incorporate them into flexible fabric and you have yourself an invisibility cloak. That's the theory anyway, and it doesn't stop at hiding objects. Building on the optical invisibility research of Professor Sir John Pendry, researchers from Imperial College, London, have now proposed that similar metamaterials could be used to conceal entire events – get ready for the "Spacetime cloak".  Read More

A new quantum computer design corrects errors when qubits are lost from the system (Image:...

The strange behavior of quantum particles that gives quantum computers such potential also has its pitfalls. One of these is the loss of information through atomic particles escaping the system, but a new study has found that this may not be as big a problem as first thought.  Read More

Researchers have created a tabletop device that produces synchrotron X-rays, the energy and image quality of which are as good as some of the largest, most expensive X-ray facilities on the planet. It uses a high power laser combined with a tiny jet of helium gas to produce an ultrashort high energy beam, that could be used for everything from examining molecules to checking the integrity of airplane wings.  Read More
