Non-invasive intracellullar 'thermometer' with fluorescent proteins developed

Non-invasive intracellullar 'thermometer' with fluorescent proteins developed | Plant Cell Biology | Scoop.it
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.

GMO Pundit a.k.a. David Tribe: False claims that GM protein Bt is present in mothers' blood and foetus tissues are based on incompetent chemical analysis

"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."

As Many Exceptions As Rules: It’s A Plant World, We’re Just Living In It

As Many Exceptions As Rules: It’s A Plant World, We’re Just Living In It | Plant Cell Biology | Scoop.it

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.

What to do with the plant vandals?

What to do with the plant vandals? | Plant Cell Biology | Scoop.it

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.

New Microscope Imaged Flow of Individual Blood Cells

New Microscope Imaged Flow of Individual Blood Cells | Plant Cell Biology | Scoop.it
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.
