7:26 AM | Exploiting Differential Gene Expression and Epistasis to Discover Candidate Genes for Drought-Associated QTLs in Arabidopsis thaliana
Nice combination of QTL mapping and gene expression analysis to identify new genes involved in drought response. From this approach, the authors "produced ranked lists of candidate genes for several drought-associated traits, including water use efficiency, growth, abscisic acid concentration (ABA), and proline concentration."See it on Scoop.it, via Plant Biology Teaching Resources (Higher Education)

8:55 PM | Camera Shy Chimp Uses A Branch to Swat A Drone Out of the Air (Video)
On Tuesday, an employee at the Royal Burgers’ Zoo in Arnhem, Netherlands was using a drone to capture some aerial footage of the zoo’s chimps. One of the chimps, a 23-year-old female named Tushi, wasn’t so keen on having the strange invader fly around her enclosure. She grabbed a long branch, climbed a tree, and when the drone flew by, she swatted it out of the air. “We can write the drone off. It cost about 2,000 euros ($2,100). Then again, it

4:05 PM | Astronauts Capture Epic Footage During Spacewalk Using A GoPro (Video)
GoPro cameras are known for being used by extreme athletes all over the world, but rarely do they find their way outside of the atmosphere. According to Yahoo News… “Back in February and March, astronauts Barry “Butch” Wilmore and Terry Virts brought GoPro cameras with them on space walks to reconfigure the space station. They captured some pretty breathtaking footage, which NASA uploaded to YouTube.”   The video gives the viewer a first-hand view of what it […]

3:00 PM | How Does a Sleep Apnea Oral Appliance Work?
Oral appliances can work wonders for people with sleep apnea. These devices are far more comfortable than wearing a mask, they’re portable so you can take them with you while traveling, and you can talk and drink water while wearing one. And, of course, they don’t involve surgery. In this article, I explain how oral... Read More » The post How Does a Sleep Apnea Oral Appliance Work? appeared first on Ask the Dentist.

8:19 AM | How to know that 'you are smart' ?
The most common measure we use to quantify a person's intelligence - the IQ test - has been subject to a whole lot of scrutiny over the past few years, with research suggesting that a person's IQ score doesn't actually mean anything. "There is no such thing as a single measure of IQ or a measure of general intelligence," a team from the University of Ontario in the US concluded in 2012. "When we looked at the data, the bottom line is [that] the whole concept of IQ - or of you having […]

7:37 AM | Secondary metabolites in plant innate immunity
Plant secondary metabolites carry out numerous functions in interactions between plants and a broad range of other organisms. Experimental evidence strongly supports the indispensable contribution of many constitutive and pathogen-inducible phytochemicals to plant innate immunity. Extensive studies on model plant species, particularly Arabidopsis thaliana, have brought significant advances in our understanding of the molecular mechanisms underpinning pathogen-triggered biosynthesis and […]

10:24 PM | NASA’s Curiosity Rover Has Discovered Liquid Water Below the Surface of Mars
For years, scientists thought that the freezing temperatures and extremely dry climate on Mars made it impossible for liquid water to exist there. Now, all that has changed. New measurements taken by NASA’s Curiosity rover indicate that there is actually liquid water just below the Martian surface. “The evidence so far is that any water would be in the form of permafrost. It’s the first time we’ve had evidence of liquid water there now,” says Andrew […]

7:13 PM | Skeleton Uncovered In Italy Yields Oldest Neanderthal DNA Ever Found
An ancient skeleton, found deeply embedded in a cave in Italy, has provided researchers with the oldest Neanderthal DNA ever found. According to Live Science… “In 1993, scientists found an extraordinarily intact skeleton of an ancient human amidst the stalactites and stalagmites of the limestone cave of Lamalunga, near Altamura in southern Italy — a discovery they said had the potential to reveal new clues about Neanderthals.” Recent research now shows that DNA […]

3:00 PM | The Complete Guide to Sugar
As a dentist, I get asked a lot about sugar. But as it turns out, sugar isn’t actually the worst thing for your teeth. Sugar also isn’t the cause of tooth decay; acid is. The most cavity-causing food is actually crackers, not candy. As someone with a major sweet tooth myself, I’ve wondered many of...
