Brazilians Welcome Genetically-Modified Mosquito To Help Fight Dengue Fever

Slashdot - Mon, 2014-04-28 01:05
An anonymous reader writes "The Brazilian government have decided to try battling the spread of dengue fever with GM mosquitoes. 'Now, with dengue endemic in three of the host cities for this summer's World Cup , Brazilian health officials are trying a radical new approach — biotechnology. They've begun a two-year trial release of Aedes aegypti mosquitoes that have been genetically modified. "We need to provide the government alternatives because the system we are using now in Brazil doesn't work," says Aldo Malavasi, president of Moscamed, the Brazilian company that's running the trial from a lab just outside of Jacobina. The new breed of Aedes aegypti has been given a lethal gene. The deadly flaw is kept in check in the lab, but the mosquitoes soon die in the wild.'"

What Happens To All the Universe's Hydrogen?

Slashdot - Mon, 2014-04-28 00:09
StartsWithABang (3485481) writes "Just a second after the Big Bang, the Universe was a hot bath of radiation, with a small fraction of protons and neutrons in about equal numbers left over. By time it was four minutes old, it was 92% hydrogen (by number of atoms) and 8% helium. Yet the Universe has aged nearly 14 billion years since then, and have formed many generations of stars, all of which burn hydrogen into heavier elements. So how much hydrogen is left, and how much will be left far into the future? A lot more than you might think."

Scientists Give Praying Mantises Tiny 3D Glasses

Slashdot - Sun, 2014-04-27 22:06
An anonymous reader writes "Scientists at Newcastle University are outfitting praying mantises with tiny 3D glasses in order to study how their vision works. From the article: 'Praying mantises have stereoscopic vision, unlike most invertebrates. This makes them sophisticated hunters, and ideal subjects for a team from Newcastle University led by vision scientist Jenny Read. By putting 3-D glasses on the mantises and faking them out, Reid and her colleagues want to learn how the insect's vision differs from ours.""

Erik Meijer: The Curse of the Excluded Middle

Slashdot - Sun, 2014-04-27 19:15
CowboyRobot (671517) writes "Erik Meijer, known for his contributions to Haskell, C#, Visual Basic, Hack, and LINQ, has an article at the ACM in which he argues that 'Mostly functional' programming does not work. 'The idea of "mostly functional programming" is unfeasible. It is impossible to make imperative programming languages safer by only partially removing implicit side effects. Leaving one kind of effect is often enough to simulate the very effect you just tried to remove. On the other hand, allowing effects to be "forgotten" in a pure language also causes mayhem in its own way. Unfortunately, there is no golden middle, and we are faced with a classic dichotomy: the curse of the excluded middle, which presents the choice of either (a) trying to tame effects using purity annotations, yet fully embracing the fact that your code is still fundamentally effectful; or (b) fully embracing purity by making all effects explicit in the type system and being pragmatic by introducing nonfunctions such as unsafePerformIO. The examples shown here are meant to convince language designers and developers to jump through the mirror and start looking more seriously at fundamentalist functional programming.'"

Fityk 1.2.9

Freshmeat - Sun, 2014-04-27 19:11
Fityk is nonlinear curve-fitting and data analysis software. It allows data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. It knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. It also enables background subtracting, data calibration, and task automation with a simple script language. It is mainly used to analyze powder diffraction patterns, chromatography, photoluminescence, infrared, and Raman spectroscopy, but it can be used to fit analytical functions to any kind of data.

Release Notes: A few optimization methods from the NLopt library have been added. A sigmoid function shape has been added. Several bugs have been fixed.
