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."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
