Opera's poisons and potions connect students with chemistry

2013-02-13
(Press-News.org) Opera audiences can feel the chemistry in romance-inspired classics like Mimi's aria from La Bohème, Cavaradossi's remembrance of his beloved while awaiting execution in Tosca and that young lady pining for her man with "O mio babbino caro" in the opera Gianni Schicchi. An article in ACS' Journal of Chemical Education, however, focuses on the real chemistry — of poisons and potions — that intertwines famous operatic plots.

João Paulo André points out that opera, in addition to being a form of theater, can be used as a teaching tool for chemistry students and the general public. In the article, based on an interactive lecture given at the University of Minho in Portugal and at other venues during the International Year of Chemistry, he cites numerous examples of themes involving chemistry that thread their way through some of the most famous operas.

One, for instance, is Samuel Barber's opera Antony and Cleopatra. In the opera, Cleopatra takes her own life with a bite from a poisonous snake. The author explains the chemistry of snake bites and venom. A complex mix of neurotoxins, venom causes destruction of the victim's tissues and even death. Others include Ambroise Thomas' Hamlet, Verdi's Simon Boccanegra and Mozart's Mitridate, Re di Ponto.

Advance promises to expand biological control of crop pests

2013-02-13
A new discovery promises to allow expanded use of a mainstay biological pest control method, which avoids the health, environmental and pest-resistance concerns of traditional insecticides, scientists are reporting. The advance toward broadening applicability of the so-called sterile insect technique (SIT) appears in the journal ACS Synthetic Biology. Luke Alphey and colleagues explain that the Lepidoptera, a large family of insects with a caterpillar stage, cause widespread damage worldwide to cotton; apples, pears and other fruits; and vegetable crops like broccoli, ...

Researchers discover biological diversity in triple-negative breast cancer

Researchers discover biological diversity in triple-negative breast cancer
2013-02-13
CHAPEL HILL, N.C. – Triple-negative breast cancers are more biologically diverse than previously believed and classification should be expanded to reflect this heterogeneity, according to University of North Carolina researchers. In a study published in the February issue of The Oncologist conducted by UNC and the Vall d'Hebron Institute of Oncology in Barcelona, Spain, a team lead by Charles Perou, PhD, of UNC Lineberger Comprehensive Cancer Center, examined more than 1,700 breast tumors, including 412 triple negative (TN) breast cancers, and concluded that triple-negative ...

Vitamin C is beneficial against the common cold

2013-02-13
Vitamin C seems to be particularly beneficial for people under heavy physical stress. In five randomized trials of participants with heavy short-term physical stress, vitamin C halved the incidence of the common cold. Three of the trials studied marathon runners, one studied Swiss school children in a skiing camp and one studied Canadian soldiers during a winter exercise. Furthermore, in a recent randomized trial carried out with adolescent competitive swimmers, vitamin C halved the duration of colds in males, although the vitamin had no effect on females. Regular ...

Kinect teleport for remote medicine

2013-02-13
The Microsoft Kinect game controller could cut the US healthcare bill by up to $30 billion by allowing physicians and other medics to interact with patients remotely so reducing the number of hospital visits and the associated risk of infection. Writing in the latest issue of the International Journal of Electronic Finance, Janet Bailey of the University of Arkansas at Little Rock is working with Bradley Jensen of Microsoft Corporation, in Irving, Texas, to explain how gaming technology could be used to "teleport" the knowledge and skills of healthcare workers to where ...

Resistance is futile

2013-02-13
A team of researchers from Russia, Spain, Belgium, the U.K. and the U.S. Department of Energy's (DOE) Argonne National Laboratory announced findings last week that may represent a breakthrough in applications of superconductivity. The team discovered a way to efficiently stabilize tiny magnetic vortices that interfere with superconductivity—a problem that has plagued scientists trying to engineer real-world applications for decades. The discovery could remove one of the most significant roadblocks to advances in superconductor technology. Superconductors are extremely ...

Magnetic shielding of ion beam thruster walls

2013-02-13
Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge channels walls, however, has limited their application to the inner solar system. A research team at Caltech's Jet Propulsion Laboratory, in Pasadena, Calif., has found a way to effectively control this erosion by shaping the engine's magnetic field in a way that shields the walls from ion bombardment. Ions are produced in Hall thrusters when electrons ...

Long noncoding RNAs control development of fat cells

2013-02-13
CAMBRIDGE, Mass. (February 13, 2013) – Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors. "We're trying to figure out what the mechanism is—what it takes to make fat cells," says Whitehead Founding Member Harvey Lodish, who is also a professor of biology and a professor of bioengineering at MIT. "The obvious reason we're interested ...

For some, deep brain stimulation brings lasting improvement in neuropathic pain

2013-02-13
Philadelphia, Pa. (February 13, 2013) – For many patients with difficult-to-treat neuropathic pain, deep brain stimulation (DBS) can lead to long-term improvement in pain scores and other outcomes, according to a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. About two-thirds of eligible patients who undergo DBS achieve significant and lasting benefits in terms of pain, quality of life, and overall health, according to the ...

Busy beavers give Canada geese a lift, study shows

2013-02-13
A new University of Alberta study shows that busy beavers are helping Canada geese get an earlier start when the birds fly home and begin spring nesting. Ponds in Alberta where beavers were active tended to result in earlier thaw of winter snowpack, giving the geese a better chance at reproductive success, according to the study, published recently in Mammalian Biology. The study is the first to link beavers to early season nesting habits of Canada geese in a Northern climate. A team led by Glynnis Hood, an associate professor in the Department of Science at the ...
