Slicing mitotic spindle with lasers, nanosurgeons unravel old pole-to-pole theory - Laser Focus world

Slicing mitotic spindle with lasers, nanosurgeons unravel old pole-to-pole theory - Laser Focus world | Plant Cell Biology | Scoop.it

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences (SEAS).


The findings, which result from quantitative measurements of the mitotic spindle, appeared in the journal Cell, on Friday 27 April.


The researchers used a femtosecond laser to slice through the strands of the organelle and then performed a mathematical analysis to infer the microscopic structure of the spindle from its response to this damage.

The Gatsby Plant Science Summer School: Inspiring the Next Generation of Plant Science Researchers

We provide evidence from a 5-year study to show that a single concerted effort at the start of undergraduate study can have a clear and lasting effect on the attitudes of students toward plant science. Attendance at a week-long residential plant science summer school in the first year of an undergraduate degree resulted in many students changing courses to include more plant science and increased numbers of graduates selecting plant-based PhDs. The evidence shows that the Gatsby Plant Science Summer School has increased the pool of high-quality plant science related PhD applicants in the UK and has had a positive impact on students’ career aspirations. The results are discussed within the context of enhancing the pipeline of future plant scientists and reversing the decline of this vulnerable and strategically important subject relevant to addressing food security and other major global challenges. We have shown that a single well-designed and timely intervention can influence future student behavior and as such offers a framework of potential use to other vulnerable disciplines.

Resident poet for botanic garden

Resident poet for botanic garden | Plant Cell Biology | Scoop.it

There once was a woman from Roath,

Who liked to feel earth 'tween her toeth,

Her new poetry book,

Could be worth a look,

Because she's almost certainly better at making rhymes than I am.

 

If you think that outreach doesn't have to be firmly mondisciplinary then this sounds like good news.

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells.

PLoS ONE: Polyhydroxy Fullerenes (Fullerols or Fullerenols): Beneficial Effects on Growth and Lifespan in Diverse Biological Models

PLoS ONE: Polyhydroxy Fullerenes (Fullerols or Fullerenols): Beneficial Effects on Growth and Lifespan in Diverse Biological Models | Plant Cell Biology | Scoop.it

Recent toxicological studies on carbon nanomaterials, including fullerenes, have led to concerns about their safety. Functionalized fullerenes, such as polyhydroxy fullerenes (PHF, fullerols, or fullerenols), have attracted particular attention due to their water solubility and toxicity. Here, we report surprisingly beneficial and/or specific effects of PHF on model organisms representing four kingdoms, including the green algae Pseudokirchneriella subcapitata, the plant Arabidopsis thaliana, the fungus Aspergillus niger, and the invertebrate Ceriodaphnia dubia.

Germany: PhD position Plant molecular biology/ cell biology at TUM | Jobs and Positions in Biology

The Department of Plant Systems Biology (Prof. Dr. Claus Schwechheimer) at the Technische Universität München (TUM) invites applications by highly motivated candidates for a Ph.D. position in the field of plant molecular biology and cell biology within the framework of the SFB924 „Molecular mechanisms regulating yield and yield stability in plants“.
Identification of novel gibberelin signaling genes
Gibberellin (GA) is a major plant hormone that controls essential transitions in plant growth such as germination, elongation growth and flowering time. While the GA hormone receptor and essential downstream components have been identified in recent years, it is still largely unclear how individual GA-mediated growth responses are regulated at the molecular level and translated into cell biological outputs.
We have identified novel GA downstream genes through an inter-species comparison of GA-regulated transcriptomes using microarrays. Goal of the advertised position is to reveal the role of individual candidate genes in the control of growth in the plant model species Arabidopsis thaliana by reverse genetics.
