News from the Dean

 

Dear Colleagues

Not much to report this week - the semester is in full swing with assignments arriving thick and fast so lots of marking ahead.

In the press last week there was some discussion regarding the financial support for research students. The Council of Australian Postgraduate Associations' (CAPA) have called for greater support for postgraduate research students as the APA stipend will drop below the poverty line by the end of 2008. Universities Australia has been calling on the Government to exempt all scholarships and bursaries from inclusion as assessable income for the purposes of Centrelink or other benefits and strongly supports CAPA's call for change. The House of Representatives Standing Committee on Industry, Science and Innovation have announced a new inquiry into research training in Australia that will consider the adequacy of support available to research students as port of its terms of reference. So here's hoping that things will improve.

MGSM is asking for donations of books for PNG for the Divine Word University and a number of Primary Schools. Divine Word are looking for reference and texts in any subject area from 2000 onwards and the Primary School appeal is looking for any children's books, in picture or novel style and any age group. Further information is available at:-
http://www.mgsm.edu.au/download.cfm?DownloadFile=9D9A6E7C-94A3-5A2F-9AD7C4441E659E64
If you would like to donate, please deliver books to Julia Wee in Biological Sciences Building E8A room 206 before 30 May.

The Wildlife Preservation Society of Australia will provide 10 grants of $1,000 each to honours or postgraduate students conducting research that will contribute to the conservation of Australian wildlife. Further information is available at http://www.wpsa.org.au/pdf/grant/grantUniForm.pdf .

Finally, a reminder that the Vice Chancellor and the Provost will be visiting ELS on Friday, May 9 at 10:30 am in the Biology tearoom to update the Division on major initiatives and changes.

Till next week
Kevin

Lesley Hughes reports in brief on her experience at the Prime Minister's 2020 Summit

 

Professor Lesley Hughes from the Department of Biological Sciences, is a specialist in the ecology of plant-animal interactions and the impacts of global climate change on terrestrial ecosystems.

Lesley is a lead author and contributing author of chapters of the Report of the Intergovernmental Panel on Climate Change (2005-2007). The Panel won a collective Nobel Peace Prize in 2007. She is also Chair of the NSW Scientific Committee (2005-present), which assesses nominations for threatened species, populations and ecological communities under the NSW Threatened Species Conservation Act 1995.

A couple of weeks ago Lesley was a "summiteer" at the prime Minister's "Australia 2020" Summit at Parliament House in Canberra. The Summit brought together some of the best and brightest brains from across the country to tackle the long term challenges confronting Australia’s future –challenges which require long-term responses from the nation beyond the usual three year electoral cycle.

Lesley shares the following about her 2020 experience:

"The weekend of the 19th and 20th of April was a very interesting time to be in Canberra. It was a humbling and exciting experience to be one of the invitees (or "summiteers" as we were called), but also an exercise in frustration. The people-spotting opportunities were second to none, from the captains of industry to the luminaries of the arts and everyone in between. Kevin and his merry band of ministers were everywhere, shaking hands and sharing the boxed lunches. There was much enthusiasm for the sharing of big new ideas and the plenary sessions in the Great Hall were full of entertainment and cheer. But what I really wanted was to have had more time in the actual working sessions to really come to terms with the issues of the day and thrash out the ideas that were being generated. The time spent in the actual "small" groups (in my case, 25 in the "Sustainability group", and then 100 in "Climate Change, Sustainability, Populations and Cities") was quite short, especially in relation to the number and size of the issues at hand. The draft document that was presented to the final plenary was the mandated one and a half pages long, so that the vast majority of the important ideas discussed, albeit briefly, were left out (somewhere in Parliament House there are a lot of sheets of butcher's paper!). But, as frequently pointed out, all this was "just the start of the conversation". I hope that the goodwill and energy generated by the event will truly be the start of a revolution - time will tell."

Paper on the Secret Sexual Behaviour of Orchids Sparks Media Attention

 

Perhaps not surprisingly, a recent paper from the Department of Biological Sciences entitled "Orchid sexual deceit provokes ejaculation" has provoked some interesting media attention, including a segment on Dutch TV (http://www.youtube.com/watch?v=QqqTadBWctQ). The paper was published in The American Naturalist by biology's own 'Orchid Voyeurs' Anne Gaskett, Claire Winnick & Marie Herberstein.

Here is a link to a story and video from New Scientist:

House Sitting Opportunity Wanted!

Ok, so at Science News we don't usually advertise like this however considering the added bonus that the subject staffer might well be able to advise you of whether your residence is flood affected or bushfire prone, we thought it worth a mention...

Risk Frontiers has a new staff member who is looking for a house-sitting opportunity in close proximity to Macquarie University.  If you are able to help could you please contact Carol Robertson on extension 9683 or email: croberts@els.mq.edu.au.

Speaking of interesting titles for papers coming out of Biology...

"SEXUAL SELECTION AND GENITAL EVOLUTION"

by Dr. Greg Holwell, Macquarie University

The rapid and divergent evolution of male genitalia is one of the most widely observed patterns for animal species with internal fertilization. Three hypotheses have been suggested to explain this pattern: pleiotropy, species isolation (lock-and-key) and sexual selection. Whilst pleiotropy and species isolation lack strong support, there is growing evidence for sexual selection as the driving force behind rapid genital evolution. I will discuss the relationship of sexual selection to genital divergence in two systems: the praying mantid genus Ciulfina and the Trinidadian guppy Poecilia reticulata. For mantids, I will discuss the influence of both the shape and size of male genitalia on copulation duration and sperm transfer, and present data relating to the role of male genitalia in reproductive isolation between Ciulfina species. For guppies I will discuss collaborative work showing that divergence in both male and female genitalia is consistent with scenarios of sexually antagonistic coevolution.

Wednesday 7th May, 1:00pm, Building E8A room 290 (Biology tearoom)

Step closer to safer cancer treatment
The discovery of a protein, which can be targeted by cancer drugs, could lead to treatments that only kill tumour cells and leave healthy ones intact.

Soil can clean toxic waste
Research has found that microbes naturally present in Australian soil could be the most efficient way to break down contaminants and toxic waste in the environment.

Timber workers risk respiratory disease
Timber workers have high dioxin levels in their blood and many are heavily exposed to PCP, resulting in an increased risk of respiratory disease, a study has found.

Elderly often forget dying wishes
Many elderly patients change their mind about end-of-life treatments, such as CPR, over a year, with many forgetting their original wishes, research has shown.

IT students' gender imbalance explained
Few girls study secondary IT because many find it uninteresting and irrelevant, while many students consider females unsuited to high level IT work, according to research.

Smoking causes gum disease
Smoking causes almost a third of all gum disease cases in Australia, often resulting in tooth loss, according to latest University of Adelaide research.

ACE2 protein better understood
A study has discovered the role of the ACE2 protein in linking nutrition and blood pressure regulation, findings that could help explain the rare Hartnup disorder.

Early intervention could stop crime
There are several risk factors that could predispose children to a life of crime, revealed new findings that may aid early intervention programs.
