Cells are the fundamental units of life. Whether they be unicellular or multicellular life forms, all living organisms are composed of and depend on cells to function normally.
What to do with the plant vandals?
Just a few more days until the threatened destruction of a field trial of GM wheat in England. At this point it's not certain if the demonstration will include vandalism, but should it, what happens next? My fantasy is to take the vandals (and the people who encourage them, like her http://tinyurl.com/83v6me2) to a quiet place for four years. During that period, they'd have to pass courses in chemistry (general, organic, and physical, because without understanding chemistry you know nothing...), statistics, economics, ecology, environmental science, genetics, cell biology, biochemistry and plant physiology. Oh, and they'd have to spend a year doing experimental work (something really hard, like proteomics or electrophysiology, or whole-organismal physiology) AND come up with a publication-quality figure. If that fail the last task, a year in a refugee camp where people know what it means to really worrry about their food could substitute..... At the end of their four years, I'd let them go. What do you think the chances would be that they'd rush off to destroy someone's experiment? I think ZERO. Via Mary Williams 
Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as a traditional blood test in real-time, simply by shining a light through the skin. This optical instrument, no bigger than a breadbox, is able to provide high-resolution images of blood coursing through our veins without the need for harsh and short-lived fluorescent dyes. 
Today is the first ever Fascination of Plants Day and I am very excited, as my Twitter friends will be able to testify (tweet ALL the plants!). All over the world there will be plant-related activities today, in Botanic Gardens, universities and research institutes. Our group will be at Oxford Botanic Garden from 10-7 pm and show people what plant parts and cells look like under the microscope! 
Students equate plant biology, for the most part, to celery—bland and unappetizing. Dab some peanut butter and raisins on that celery, and though you may run the risk of sounding very corny, the students will have at least remembered why that celery was green. 
Plants don't always seem particularly charismatic, but hidden from us in their slow-motion and chemical activities are incredible mechanisms that sense and respond to the world ...

Book by Martin Hodson (Oxford Brookes Univ.) and John Bryant (University of Exeter) - nice Facebook page with lots of plant links. 
A small molecule able to move independently along a track has been developed by researchers at the University of Edinburgh. 
In which I construct a six foot tall microscope, and so can you! 
Though producing 3D images with an electron microscope isn't the newest of the new, being able to display the 3D images in real time is, which is why it's pretty neat that a Japanese research group has created an electron microscope that does just... |
Biologists have developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes. "In short, Aris and Leblanc report results which are mechanistically implausible because protein in the diet rarely enter the body as intact molecules, and which are highly likely to just represent low-level noise in their complicated assay system.
They should have at least explicitly recognised the limitations of their assay in their paper and warn against the misinterpretation highly preliminary and non-specific signal, because such misinterpretation is obvious to anyone with experimental experience in these assays, or a good training in biochemistry.
The author of this post has that kind of experimental experience and has developed assays using the same kind of technology for other biological components, and even published and patented discoveries made using this technology." 
Kinesins, molecular motors key to cellular transport, can exhibit spiral motion, challenging assumptions that kinesins move only on straight paths. 
What happens when you ask a bunch of 14 year old girls to each write a question on a piece of paper anonymously and put it in the middle of the table for a... 
Tomorrow - or rather today by the time I finished writing this - I will be opening my bench and my blog to a small group of very enthusiastic 14-15 year ... 
Life on Earth is easy. It can be boiled down to three sentences. “The mitochondria and the chloroplasts are, in a fundamental sense, the most important things on Earth. Between them, they produce oxygen and arrange for its use. In effect, they run the place.” Lewis Thomas wrote this in his award winning book, The Lives Of The Cell: Notes Of A Biology Watcher, in 1975. 
To comprehensively grasp cell biological events in plant stomatal movement, we have captured microscopic images of guard cells with various organelles markers. 
"A new study from the University of Guelph has overturned a century of dogma by suggesting that chloroplasts may live as independently from one another as they do from the plant cells that host them." 
This flying microscope is a tool which [Darrell Taylor] can be very proud of. He wanted to have an inspection microscope for working with surface mount projects. 
Will humans one day live on other planets than on Earth? I don’t know the answer to that. But I know that if humans attempt to settle on extraterrestrial land, we will want to take plants with us to provide us with food and make our air breathable 
Flowers and leaves are made up of thousands of tiny little blocks we call plant cells. Those cells have a very strong, rigid wall that keeps all of the contents inside. Inside each of the building blocks are chemicals called ... |
