7:21 PM | The demise of ScienceOnline
So it seems that the pioneering science communication conference Science Online is no more. It's a sad piece of news, especially since I attended the conference twice and had registered to attend it again in Atlanta next year.The news is sad but it's not entirely surprising; in fact I got the first whiff that something might be wrong when I was getting emails asking me to encourage others to register even one week after registration opened (usually registration sells out in minutes). The events […]

5:33 PM | Tiny robots armed with new force-sensing system to probe cells
Inexpensive microrobots capable of probing and manipulating individual cells and tissue for biological research and medical applications are closer to reality with the design of a system that senses the minute forces exerted by a robot's tiny probe.

4:32 PM | Legislation Looks at Lavender Labeling
In the EU lavender oil, or any products containing lavender oil, may soon come with a warning label. (By soon I mean 2018.) Lavender oil is generally used as a fragrance, but can also be an antiseptic and an anti-inflammatory. According to WebMD people claim lavender is good for depression, insomnia, headache, toothache, colic—the list goes […]

3:14 PM | Researchers make first observation of atoms moving inside bulk material
Researchers have obtained the first direct observations of atomic diffusion inside a bulk material. The research could be used to give unprecedented insight into the lifespan and properties of new materials.

1:27 PM | Tailored flexible illusion coatings hide objects from detection
Developing the cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick.

12:52 PM | Dinosaur Mode
I had some very strange dreams towards morning including this gem: a cellphone that would mock me. Every time I would try and do something with it such as texting, a picture of an apatosaurus-type dinosaur would appear on the screen, implying that I was using an old, outdated technique and that faster, more efficient options now existed. That's not fair! I can't text as fast as my son (whose replies seem to violate the space-time continuum), but I'm more than able to find an efficient option […]

11:44 AM | Public attitudes to chemistry: ​take part in our research!
As you will have seen in the latest issue of RSC News we are working on a piece of research to inform how we should communicate with the public. We are developing this project with a leading market research company, TNS BMRB and their researchers are eager to listen to your ideas and learn from your experiences in communicating chemistry to non-chemists. We hope you can spare few minutes to take part in this online survey and help us in this important research. Thank you.Posted by […]

11:00 AM | Why You Should Care about Auditory Myosin
By: Lina Jamis, 2nd year student in the Anatomy Graduate Program As much as we may enjoy denying it, our hearing is slowly, but surely, leaving us. In fact, considering how we often may follow the adage  “louder is better,” we’re probably headed for hearing aids sooner than we think. (That goes doubly for you, Skillrex fans).…

9:21 AM | New battery uses nanotubes to recharge to 70% in just two minutes
Researchers have developed a new battery that can be recharged up to 70 per cent in only 2 minutes. The battery will also have a longer lifespan of over 20 years.

9:12 AM | Nanoenhanced 'smart' lithium-ion battery warns of fire hazard (w/video)
Scientists have developed a 'smart' lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.

7:45 AM | Multifunctional RNA nanoparticles to combat cancer and viral infections
There is a significant need for new therapeutic approaches to combat diseases such as cancer and viral infections. Using RNA as a therapeutic modality brings to bear an entirely new approach, which not only allows for the construction of uniform scaffolds for attachment of functional entities, but also permits the use of all the different types of functionalities that are inherent in natural RNAs. New research demonstrates that multifunctional RNA nanoparticles with a nanoring design allow the […]

11:57 PM | The age of earth's water, and how to draw a conclusion.
One theme of my posts that I have raised more than once is that while scientists are very good at collecting information and of measuring things, this leaves the problem of interpreting what it means. Scientific theory is based on either propositions or statements. A proposition is of one of two forms: (1)  If theory P is true, then you will observe A (2)  If and only if theory P is true, then you will observe A Failure to observe A falsifies either proposition, but if you observe A, […]

4:29 PM | This Week in Chemistry: The Chemistry Nobel & Writing in Gold in Cells
This week, the award of the Nobel prizes, including the Nobel prize in chemistry, has dominated the headlines. However, there’ve been a range of other interesting stories too, including researchers succeeding in writing gold characters inside cells, and the development of a green tea-based anti-cancer drug delivery system. Links to articles and original research papers […]

5:27 AM | Nanomaterials and toxicity
A couple of weeks ago I commented on the toxicity of carbon nano tubes. Well here is a timely review of the literature by Prof. Krug, discussing the toxicity of “engineered nanomaterials (ENMs)”. He examined 10,000 publications which appeared since 2000 for features pertaining to human health effects of studies involving some sort of biological conclusion. […]

5:09 PM | Parking some links for discussion
From this week, but not been addressed:I liked this Boston Globe story on life science postdocs. Nothing hugely groundbreaking for those in the know, but it's good that people are continuing to cover the issue and that professors like Greg Petsko are getting attention. On the other hand, I found this response to concerns about the glut of life science Ph.D.s to be insufficient, but of course, I would. Via "JJ", I see the Denver school teacher that burned some students doing a […]
