Sawfish are avoiding extinction by reproducing without sex This is the first time 'virgin births' have been seen in a vertebrate species in the wild.

Image
 A routine DNA study has discovered that endangered female sawfish in Florida are producing offspring without first mating with males.
This 'virgin birth' process is known as parthenogenesis, and has previously been observed in certain shark, snake and fish species living in captivity. But this is the first time scientists have observed asexual reproduction occurring in a wild vertebrate species, which suggests the process could be more common in vertebrates than previously thought. The discovery was made while researchers were examining the DNA of 190 smalltooth sawfish captured in southern Florida to find out if they were regularly breeding with their family members because of their smallpopulation size. "What the DNA fingerprints told us was altogether more surprising: female sawfish are sometimes reproducing without even mating," said lead author Andrew Fields from Stony Brook University in the US. In fact, one population of sawfish was made up of 3 percent parthen…

Healthy skin cells harbour a high number of cancer-causing mutations And apparently, it's completely normal.

Image
A quarter of healthy skin cells could harbour cancer-causing mutations resulting from Sun exposure, a new study by researchers in the UK suggests. The finding offers clues about the transition of cells from a healthy to a cancerous state, and demonstrates how normal tissue analysis can provide clues about the origins of the disease.It was previously thought that tumour-forming cell mutations were rare, and occurred just before the onset of cancer.But this latest study, which examined healthy eyelid skin that was removed from four patients during cosmetic surgery, has revealed that these cancer-linked mutations "are staggeringly common in normal skin," one of the team, oncologist Philip Jones from the University of Cambridge, told Tina Hesman Saey at Science News.The researchers performed ultra-deep gene sequencing on 234 biopsies of skin taken from the four patients, who were aged between 55 and 73. They were scanning for 74 known mutations.They found that about 25 percent of…

Don’t Be Google..!!!!!!

Image
Dear Google: what happened? Android sales are falling. Chrome has become a bloated hog. Analysts are calling you the new Microsoft, or, much worse, “the new Yahoo!” And most damning of all: you have squandered our trust. You used to be special, Google. Or at least we used to believe you were special. But you seem more and more like just another megacorporation.


Does that sound harsh? Consider the Zoe Keating kerfuffle:

YouTube gave Keating a take-it-or-leave contract, some terms of which were unacceptable to her. Some of the terms were also pretty hard to understand […] As YouTube now explains it — following a public debate following Keating’s blog post — Keating has a relatively simple choice […] These responses go against descriptions of the agreement presented to Keating (and transcribed by her) by YouTube previously, and presumably represent an update to the contract’s terms.At best, Google is guilty of incredibly confusing and heavy-handed communication, something they have long be…

New app lets you control exactly how much energy each appliance uses

Image
Australia's national science organisation, the CSIRO, has developed a new app that lets you remotely keep track of exactly how much money you're spending on electricity at any given time - and even lets you monitor and control individual appliances from your phone.
While we can already stay on top of how much electricity our houses are guzzling on a daily basis using smart meters, the new prototype app - which is called 'Eddy' - wants to take things one step further by putting people in control of their power consumption, with the overall aim of saving people money and reducing greenhouse gas emissions. 
Right now the app only works on big devices such as air conditioners and pool pumps, but the developers are hoping that in the future they'll be able to take it down to the level of monitoring and turning on and off individual lightbulbs.
