How Mt Everest got it’s name

Andrew Waugh, the British Surveyor General of India was looking for a name of what had been found to be the highest mountain in the world, he argued that he could not find any commonly used local name. Waugh’s search for a local name was hampered by Nepal and Tibet’s exclusion of foreigners. Many local names existed, including “Deodungha” (“Holy Mountain”) in Darjeeling and the Tibetan “Chomolungma”, which appeared on a 1733 map published in Paris by the French geographer D’Anville. Waugh argued that … Continue reading

A rare interview with Peter Higgs

Almost 50 years ago, British physicist Peter Higgs first hypothesized the existence of the particle that bears his name. Now we’re on the verge of finding the Higgs boson, and Peter Higgs himself offers his own thoughts on it all. Generally speaking, the now retired Professor Higgs doesn’t give many interviews. But he was recently announced as this year’s recipient of the Edinburgh Award by his adopted hometown, and in the past week he gave a pair of interviews, one … Continue reading

New device for acute stroke patients

A new approach to stroke treatment initially developed by Dr. Jeffrey Saver’s group at the UCLA Stroke Center combines the ability to restore circulation and remove clots using only a single device … and it’s showing significant promise in trials. In a study comparing the Covidien Solitaire FR Revascularization Device with the FDA-approved Merci Retriever, the device successfully and safely treated roughly 60 percent of stroke patients, compared to roughly 30 percent when the Merci Retriever was used. Such treatment … Continue reading

Math can save Tylenol overdose patients

University of Utah mathematicians developed a set of calculus equations to make it easier for doctors to save Tylenol overdose patients by quickly estimating how much painkiller they took, when they consumed it and whether they will require a liver transplant to survive. “It’s an opportunity to use mathematical methods to improve medical practice and save lives,” says Fred Adler, a professor of mathematics and biology and coauthor of a study that developed and tested the new method. The study … Continue reading

Scientists score victory over uncertainty

Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning. For scientists working in quantum physics, the Heisenberg Uncertainty Principle says that measurements of properties such as the momentum of an object and its exact position … Continue reading

Scientists image the charge distribution within a single molecule for the first time

IBM scientists were able to measure for the first time how charge is distributed within a single molecule. This achievement will enable fundamental scientific insights into single-molecule switching and bond formation between atoms and molecules. Furthermore, it introduces the possibility of imaging the charge distribution within functional molecular structures, which hold great promise for future applications such as solar photoconversion, energy storage, or molecular scale computing devices. As reported in in the journal Nature Nanotechnology, scientists Fabian Mohn, Leo Gross, Nikolaj … Continue reading
