3:20 PM | A vitamin pill a day keeps cancer away? Unlikely

The media’s search for a ‘magic pill’ to reduce cancer risk continues. Yesterday saw several stories about multivitamins “lowering the risk of cancer”. Some of the headlines would have you believe the magic pill has been found – but unfortunately it’s … Continue reading →

The well-qualified amateur who threw the spotlight back on CO2

75 years ago Guy Callendar revealed calculations and temperature measurements linking rising 20th century temperatures to burning fossil fuels, helping to lay the foundations for understanding the global warming that is still ongoing today.

Computer science on prediction and the edge of chaos

With the development of statistical mechanics, physicists became the first agent-based modellers. Since the scientists of the 19th century didn’t have super-computers, they couldn’t succumb to the curse of computing and had to come up with analytic treatments of their “agent-based models”. These analytic treatments were often not rigorous, and only a heuristic correspondence was […]

What music do dogs prefer? Bach vs. Snoop Dogg

Hey Julie,I hope you've had a fun week. I saw a new in-press publication with your name on it - "Smelling more or less: Investigating the olfactory experience of the domestic dog" - looks like a really great study, and so timely after my last post about dogs and olfactory enrichment! Looking forward to reading it (and all those other cool Learning and Motivation articles) over the weekend. So did you do your homework? Did you watch this clip from the Sydney Opera […]

Did you like this photo? No, really like…

Researchers in Germany and the US have developed an algorithm that can work out whether comments on a photo or video (and eventually any shared digital document) are being positive or negative about the quality of the photo, or critical about the subject of the photo itself. So a blurry, underexposed snap of Justin Bieber [...]Related Posts:Media, marketing, mutualitySaving power on the cloudDoubling broadband brings 0.3% economic “boost”Wikimaps plots important points on Wikipedia8 […]

A State of Dis”array”: Two Recent Studies Highlight Common Problems Associated with Using Illumina’s 450k Array for Epigenetics Research

Epigenetic analysis is one of the hottest areas in all of biological research. Covalent modifications to DNA, proteins, and RNA, without changing the primary sequence of these molecules, are known to epigenetically regulate numerous cellular processes and contribute to many important human disease phenotypes. One of the most intensely studied epigenetic modifications is DNA methylation ...
