Why don't more students enter science careers?
Maybe because the job sucks?
There’s a refreshingly honest quote in this blog post, to which I’ve added some emphasis:
“People were questioning why there weren’t more women in science, and I had to point out that we are not going to be banging down the doors to enter a profession that just sounds so awful,” said Wu, who just completed her doctorate at the Pratt School of Engineering at Duke.

Most of data sharing policies share some common principles such as protecting the cumulative data outputs, recognizing data as a public good and data sharing as strong value chains of innovation for subsequent scientific exploitation. A improved data access and sharing not only helps to maximize the research potential but it also reinforces open scientific research which encourages diversity of analysis and opinion. In a latest article published in October 9 issue of journal Science, Dawn Fiel........ Read more »
I would never select Treponema pallidum as my experimental model if I had to study gene regulation in a spirochete. The main problem is that no one has figured out how to grow T. pallidum in any type of culture medium. T. pallidum can be propagated only by growing the spirochete in the testes of rabbits. Consequently, investigators have not even begun to develop the genetic tools (e.g., gene knock outs, shuttle plasmids) necessary to unravel the regulatory mechanisms that control T. pallidum ........

The new Science has an extremely impressive paper tackling the problem of orphan enzymes. Due primarily to Watson-Crick basepairing, our ability to sequence nucleic acids has shot far past our ability to characterize the proteins they may encode. If I want to measure an RNA's expression, I can generate an assay almost overnight by designing specific real-time PCR (aka RT-PCR aka TaqMan) probes. If I want to analyze any specific protein's expression, it generally involves a lot of teeth gnashi........ Read more »

Autophagy seems to be the topic of the week, and here's another example of research demonstrating enhanced longevity in laboratory animals through increased autophagy: Here, we report that administration of spermidine, a natural polyamine whose intracellular concentration declines during human ageing, markedly extended the lifespan of yeast, flies and worms, and human immune cells. In addition, spermidine administration potently inhibited oxidative stress in ageing mice [and] led to significant ........ Read more »

Boyish good looks - the next generation of sexy?I couldn't help but notice that a new study has come out about the behavioral effects of hormonal contraception. It's all over the science news sites. With titles ranging from the conservative "Pill May Change Attraction" to the bolder "Taking the pill for past 40 years 'has put women off masculine men'"and "The pill 'gives women a taste for boyish men like Zac Efron'," this new publication has swept the media outlets by storm. This idea that birth........ Read more »

At the start of the 20th Century, the sociologist Max Weber came up with a famous theory to explain why Northern Europe and North America were so prosperous: the Protestant Work Ethic.Basically, the idea was that a unique feature of Protestant Christianity is its emphasis on work as a duty to God. While other religions asked people to do things that were laborious and time consuming, only Protestantism (so the theory went) channelled that religious duty into productive work.It's important to tak........

SECOND LIFE is an online "virtual world" which enables users to create a customised avatar, or digital persona, with which they interact with each other. Since its launch just over 6 years ago, it has become incredibly popular, with millions of "residents" now using it regularly to meet others, interact with them, and even to have sex. Users have also established virtual universities, businesses and a virtual economy.
Now, imagine a futuristic version of Second Life, in which avatars can trans........ Read more »

Classical Indian dancing is a tradition that extends back 2,000 years. Unlike much Western dance, it is intended to express specific emotions and tell detailed stories. The Natyasastra, a text from the first or second century A.D., offers instructions for how to depict nine primary emotions, and these rules continue to be followed in Indian Classical dance today. This movie demonstrates one form of Indian Classical dance:
As you can see, each gesture has a highly-specific meaning, which, to ........ Read more »

A study claims that it's possible to immunize against cocaine: Cocaine Vaccine for the Treatment of Cocaine Dependence in Methadone-Maintained Patients. But does it work? And will it be useful?The idea of an anti-drug vaccine is not new; as DrugMonkey explains in his post on this paper, monkeys were being given experimental anti-morphine vaccines as long ago as the 1970s. This one has been under development for years, but this is the first randomized controlled trial to investigate whether it he........ Read more »

Shortly after I developed sore throat, cough, and congestion last week, a package of 'Cold - Eeze' materialized on my kitchen counter.

Birds are often touted as the monogamists of the animal kingdom, with most bird species mating with the same individual and displaying biparental care, sometimes for many years. Their cousins, the reptiles, are no match for their faithfulness: most reptiles show no mate fidelity, let alone parental care.
But a new [...]

Infrared observations using the Spitzer Space Telescope, published by Verbiscer et al (2009, Nature), have revealed the largest known ring around Saturn, an annulus of very tenuous material extending between 6 million and 18 million kilometers from Saturn, and tilted by 27 degree from the plane of the traditional rings (which only extend out to ~240,000 km).The material in the new ring comes from the battered and cratered moon Phoebe. Of more interest, this new dust ring explains why the leading........ Read more »

Today's Nature contains a great paper which is one more step forward for cancer genomics. Using Illumina sequencing a group in British Columbia sequenced both the genome and transcriptome of a metastatic lobular (estrogen receptor positive) breast cancer. Furthermore, they searched a sample of the original tumor for mutations found in the genome+transcriptome screen in order to identify those that may have been present early vs. those which were acquired later.From the combined genome sequence........
