E-cigarettes 'Potentially As Harmful As Tobacco Cigarettes' (uconn.edu)
An anonymous reader shares a report: A study by chemists at the University of Connecticut offers new evidence that electronic cigarettes, or e-cigarettes, are potentially as harmful as tobacco cigarettes. Using a new low-cost, 3-D printed testing device, UConn researchers found that e-cigarettes loaded with a nicotine-based liquid are potentially as harmful as unfiltered cigarettes when it comes to causing DNA damage. The researchers also found that vapor from non-nicotine e-cigarettes caused as much DNA damage as filtered cigarettes, possibly due to the many chemical additives present in e-cigarette vapors. Cellular mutations caused by DNA damage can lead to cancer. -
Study: Push Notifications As Distracting As Taking a Call
itwbennett writes: Researchers at Florida State University have found that simply being aware of a missed call or text can have the same damaging effect on task performance as actually using a mobile phone. 'Although these notifications are short in duration, they can prompt task-irrelevant thoughts, or mind-wandering,' the researchers wrote in their paper. In further bad news for chronic multitaskers, a new study by researchers at the University of Connecticut finds that 'students who multitasked while doing homework had to study longer, and those who frequently multitasked in class had lower grades on average than their peers who multitasked less often.' -
Researchers Use Salmon DNA To Make LED Lightbulbs
Al writes "Researchers from the University of Connecticut have created a new light-emitting material by doping spun strands of salmon DNA with fluorescent dyes. The material, which is robust because DNA is such a strong polymer, absorbs energy from ultraviolet light and gives off different colors depending on the amounts of dye it contains. A team led by chemistry professor Gregory Sotzing created the new material by mixing salmon DNA with two types of dye, then pumping the solution from a fine needle while a voltage is applied between the needle tip and a grounded copper plate covered with a glass slide. As the liquid jet comes out, it dries and forms long nanofibers that are deposited on the glass slide as a mat. The researchers then spin this nanofiber mat directly on the surface of an ultraviolet LED to make a white-light emitter. The color-tunable DNA material relies on an energy-transfer mechanism between two different fluorescent dyes, and the DNA keeps the dye molecules separated at a distance of 2 to 10 nanometers from each other." -
Checking Web Content for Sensitive Data?
NetFiber asks: "I work as a security analyst for a large university. We have recently been tasked to scour our network in the hopes of finding and removing sensitive information such as credit card numbers, social security numbers, and such on all publicly available web servers. Our current method of analysis is to archive all the content (which often grows over 100GB) and later parse the data with various utilities and regexes that search for patterns and other pertinent information. So far, this process has proven to be rather cumbersome and time consuming. Does anyone have any experience collecting and sanitizing large amounts of web content? If so, what procedures/utilities do you use to accomplish this?" -
Rare "Corpse Flower" Set To Bloom
BearJ writes "And you thought Halley's comet was rare. For the first time in the northeast since the 1930s, a Corpse Flower, or 'Amorphophallus Titanum' is set to bloom at the University of Connecticut. Check out the press release and the official page . Oh, and it's called the corpse flower due to its putrid smell, apparently to attract dung beetles. I wonder if I could find some for my garden..." -

Innovative Uses for a Computer Classroom?
flard asks: "I will be teaching a Freshman English class at a medium sized public university, in a computer classroom for next semester. Every student has their own machine with an internet connection. I am thinking about using a weblog for them to post their work and critique each other. Do you guys have any other cool ideas on what to do and what NOT to do?" How can the computers best be applied to assist in teaching a non-technical class? Use of a weblog is a start, but are there other pieces of software that can be deployed in such a setting? -

Building Objects With Water
kjeldor writes "According to this NASA article, an experiment conducted on water in space shows that a metal loop dipped into water can sustain a thin membrane of water (just like soap bubbles) in diameters up to 4 or 5 inches without breaking. This surface can be moved around, painted on, etc. without breaking. Apparently, with the absence of gravity's pull to break the intermolecular forces, water has the ability to hold together into a membrane in an unconventional manner. This may lead to some interesting future projects." -
Odyssey Leaves For Mars on Saturday
rizzo420 writes: "Looks like NASA is returning to Mars according to this article in the Washington Post. The main objective for this mission is to map the planet to gain a better understanding of the mineral makeup, and as usual, to determine if it is possible that life ever existed on Mars. Overall, it's a pretty interesting read. The article goes into a little detail about the instruments that will be used in the mapping of the Martian surface."
