Fruit flies drawn to the sweet smell of youth

Aging takes its toll on sex appeal and now an international team of researchers led by Baylor College of Medicine and the University of Michigan find that in fruit flies, at least, it even diminishes the come-hither effect of the chemicals of love - pheromones.

"This is new because we have direct evidence that the pheromones produced at these different ages affect sexual attractiveness differently," said Tsung-Han Kuo, a graduate student in the department of molecular and human genetics and the Huffington Center on Aging at BCM. Kuo is first author of the report that appears online in the Journal of Experimental Biology.

Pheromones are chemicals produced by an organism to communicate or attract another. In this case, Drosophila melanogaster or fruit flies produce chemicals called cuticular hydrocarbons.

Special mass spectrometry studies that looked in detail at the composition and level of production of these hydrocarbons showed that they differed between the sexes, but more important, they changed with age.

"Fruit flies like a banana" is a proposition in entomological gastronomy, whereas "Fruit flies like a banana" is a proposition in horticultural aerobatics. These two subjects, while they are important intellectual disciplines demanding our utmost respect, are still in their infancy, and unfortunately we cannot rely on them for more than tentative, if hopeful, guesses as to whether fruit flies do like a banana, or as to whether fruit does fly like a banana, The important fact is that the two fields have as yet no common ground; at present, no reputable interdisciplinary work has been done in both at once; no joint degree has been taken in entomological gastronomy as applied to horticultural aerobatics; no lecture entitled "Fruit flight and the diet of Drosphila: bananism versus pomegranity" has been read, There is no connection between the two sentences.

Perspective: Questing for Blue Oceans - Science Careers - Biotech, Pharmaceutical, Faculty, Postdoc jobs on Science Careers

It may be useful to think about science's recent development -- from breakthroughs by individuals like Einstein, Curie, or Bohr to well-planned research programs involving teams of scientists -- as analogous to companies, which start out small and innovative. Something valuable and audacious is lost when they grow into billion-dollar megacorporations. As Harvard Business School Professor Clayton M. Christensen explained in his book, The Innovator´s Dilemma, large companies tend to ignore disruptive innovations and focus on what they perceive as the demands of their current customers. They forget that real business value comes from creating new market opportunities. Henry Ford, who produced the first affordable automobile, is claimed to have said, "If I'd asked people what they wanted, they would have asked for a better [or, in some versions, faster] horse." The quote may be apocryphal, but it helps to make this point: Rather than improving already existing products and services, disruptive innovators create demand for products and services that customers don't yet know they need. Such novel markets were dubbed "blue oceans" by INSEAD business school professors W. Chan Kim and Renée Mauborgne in their book Blue Ocean Strategy.

Coming up with disruptive ideas is a job great scientists do, too. Darwin's theory of evolution by natural selection and Einstein's theories of relativity are examples of blue oceans opened up by disruptive scientists. Unfortunately, it is becoming increasingly difficult for scientists to practice disruptive science. The academic career puts pressure on immediate results, continuous publication, and countless academic and administrative duties, especially early on. Meanwhile, there is little incentive for scientists to be ambitious. Increased specialization of scientific research, pressure to pursue mainstream topics, and the difficulty of obtaining grant money for the most audacious projects encourage scientists to focus on the incremental.

Sun team probing sustained criminality: source | Reuters

(Reuters) - An investigation into Rupert Murdoch's top-selling British newspaper, the Sun, has uncovered evidence that it paid tens of thousands of pounds in retainers to public officials for tipoffs, a source with knowledge of the probe said on Wednesday.

Much of the evidence passed to police has been provided by Murdoch's own News Corp group, and deepens a crisis at the Sun, where officers have arrested nine former and current senior staff in recent weeks over illegal payments.

Murdoch has been trying to regain the high ground ever since an outcry last summer - over revelations that his journalists had hacked the voicemails of crime victims and their families - forced him to close the profitable News of the World title and abort a planned multibillion-dollar buyout of Britain's biggest satellite broadcaster.

"This is not about sources or expenses, this is an investigation into serious suspected criminality over a sustained period," the source said, speaking on condition of anonymity.

Independent - Front Page - You couldn't make it up: Sun staff hope Strasbourg can save them from Murdoch

The crisis in Rupert Murdoch's news empire deepened last night when Sun journalists began planning legal action against their employer with the help of two things they have previously shunned - the Human Rights Act and the National Union of Journalists.

Several senior journalists have contacted the NUJ - to which they do not belong because News International has its own staff organisation - seeking its help in putting together a case claiming that the parent company has breached their right to freedom of expression by passing information about their sources to the Metropolitan Police.

Which is interesting given their normal attitude to anything European

The Sun says: The usual editorial line

'I am happy to point out the cases where the Act has been used to right a real wrong... Except that I can't think of any'

Jane Moore, 27 April 2011

'Soft judges must not put the human rights of dangerous fanatics above the right of decent citizens to live in safety'

Trevor Kavanagh, 28 may 2007

'We'd love to see Britain ignoring orders from Strasbourg judges that stop us deporting foreign killers'

Sun editorial, 21 September 2011

'How truly awful ... Is belonging to Europe a price worth paying for allowing creeps like this to hide behind the Human Rights Act?'

Acta loses more support in Europe | Technology | guardian.co.uk

Support for Acta in Europe is waning as both Bulgaria and the Netherlands refuse to ratify the international anti-piracy agreement.

Bulgaria will not ratify the Anti-Counterfeiting Trade Agreement over fears it will curb freedom to download movies and music for free and encourage internet surveillance, economy minister Traicho Traikov said on Tuesday.

More than 4,000 people marched in the capital Sofia last Saturday calling on parliament not to ratify the act. Similar rallies drew thousands of protesters across eastern Europe, as well as in Germany, France and Ireland.

Met probes claims that Sun paid some public officials more than £10k a year | Media | guardian.co.uk

The Scotland Yard investigation into alleged illegal payments by Sun journalists to police and other public officials is looking into claims that some individuals received more than £10,000 a year and were "effectively on retainer".

News Corporation's controversial internal unit passing information about alleged illegal practices by News International journalists to the Metropolitan police believes it has uncovered evidence of "serious suspected criminality over a sustained period" by some public officials supplying information to the Sun.

The revelation will almost certainly mean that Rupert Murdoch, the New York-based News Corp chairman and chief executive, will not seek to rein in the management and standards committee when he arrives in London on Friday for what are now almost certain to be crisis talks with News International management.

Any idiot can face a crisis - it's day to day living that wears you out.
