In 1905, American astronomer Percival Lowell predicted the existence of a new planet he called Planet X. Lowell proved that this new planet existed even though no one had been able to see it in the sky. Twenty-five years later, astronomer Clyde Tombaugh stumbled on images of X photographed from the Flagstaff Observatory in Arizona. Today, that planet is known as Pluto.
While it took twenty-five years for astronomers to go from theory to confirmation of Pluto’s existence, it took genome scientists barely three months in 2003 to confirm a revolutionary new view of what happens in the human genome to cause dramatic evolutionary changes. Now, bioinformaticians at the University of California, San Diego (UCSD) -- who posited that ’fragile’ regions exist in the human genome that are more susceptible to gene rearrangements -- are collaborating with biologists to see if their new theory can yield potentially life-saving insights into diseases such as breast cancer, in which chromosomal rearrangements are implicated.
"It took only three months to go from theory to hard scientific evidence that there are regions of the genome that are subject to evolutionary ’earthquakes’ over and over again," says Pavel Pevzner, who holds the Ronald R. Taylor Chair in computer science and engineering at UCSD’s Jacobs School of Engineering. "That is representative of how quickly knowledge is advancing in bioinformatics, and how useful this research can be for medicine and other fields."

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
