Nature Insight Exotic matter

Bring together a large number of particles, and they can order
themselves in unusual ways, giving rise to emergent phenomena that
cannot be understood solely in terms of the interactions that rule
at the microscopic level. This Insight exposes examples of matter for
which the maxim 'more is different' holds true in particularly
striking ways.

explains how mass migration to cities brings out people's
resourcefulness, but also how the speed of social and environmental
change leads them to seek meaning in their lives.

The integrase protein of retroviruses such as HIV-1 catalyses
insertion of the viral genome into that of the host. Here, the
long-awaited structure of the full-length integrase complex is

Somatic sex identity is cell autonomous in the chicken pp237-242
In mammals, embryos are considered to be sexually indifferent until
the action of a sex-determining gene initiates gonadal differentiation.
Here it is demonstrated that this situation is different for birds.
Using rare, naturally occurring chimaeric chickens where one side of
the animal appears male and the other female, it is shown that avian
somatic cells possess an inherent sex identity and that, in birds,
sexual differentiation is cell autonomous.

Systems survey of endocytosis by multiparametric image analysis pp243-249
A new strategy is presented to accurately profile the activity of
human genes in endocytosis by combining genome-wide RNAi, automated
high-resolution confocal microscopy and quantitative multi-parametric
image analysis. Several novel components of endocytosis and endosome
trafficking were uncovered; a systems analysis further revealed that
the cell regulates the number, size and concentration of cargo
within endosomes.

Confirmation of general relativity on large scales from weak lensing
and galaxy velocities pp256-258
Although general relativity underlies modern cosmology, its applicability
on cosmological length scales has yet to be stringently tested. Now, at
a length scale of tens of megaparsecs, the quantity EG, which combines
measures of large-scale gravitational lensing, galaxy clustering, and
the growth rate of structure, has been measured to be 0.39[plusmn]0.06,
in agreement with the general relativistic prediction of about 0.4.

Deviations from a uniform period spacing of gravity modes in a massive
star pp259-261
Measuring the oscillations of a star can allow the various mixing
processes in its interior to be disentangled, through the signature
they leave on period spacings in the gravity mode spectrum. Here
numerous gravity modes in a young star of about seven solar masses
are reported: the mean period spacing enables the extent of the
convective core to be determined, and the clear periodic deviation
from the mean constrains the location of the chemical transition
zone — at about 10 per cent of the radius.

Transmission of electrical signals by spin-wave interconversion in a
magnetic insulator pp262-266
An insulator does not conduct electricity, and so cannot in general
be used to transmit an electrical signal. But an insulator's electrons
possess spin in addition to charge, and so can transmit a signal in
the form of a spin wave. Here a hybrid metal-insulator-metal structure
is reported, in which an electrical signal in one metal layer is
directly converted to a spin wave in the insulating layer; this wave
is then transmitted to the second metal layer, where the signal can
be directly recovered as an electrical voltage.

Tunable polymer multi-shape memory effect pp267-270
When a shape memory polymer is deformed at a temperature defined by

different shapes as a result of its broad reversible phase transition.

A large atomic chlorine source inferred from mid-continental reactive
nitrogen chemistry pp271-274
The presence of gaseous chlorine atom precursors within the troposphere
was thought only to occur in marine areas but now nitryl chloride has
been found at a distance of 1,400 km from the nearest coastline.
A model study shows that the amount of nitryl chloride production in
the continental USA alone is similar to previous global estimates for
marine regions. A significant fraction of tropospheric chlorine atoms
may arise directly from anthropogenic pollutants.

Antagonistic coevolution accelerates molecular evolution pp275-278
The Red Queen hypothesis predicts that coevolution should increase

that coevolution drives greater diversification of phage populations.

Compensatory evolution in mitochondrial tRNAs navigates valleys of

Evolution from one fitness peak to another must involve either
transitions through intermediates of low fitness or skirting round
the fitness valley through compensatory mutations elsewhere. Here,
the base pairs in mitochondrial tRNA stems is used as a model to show
that deep fitness valleys can be traversed. Transitions between AU
and GC pairs have occurred during mammalian evolution without help
from genetic drift or mutations elsewhere.

Sister chromosome pairing maintains heterozygosity in parthenogenetic
lizards pp283-286
The existence of all-female species of whiptail lizard, formed as a
hybrid between sexual species, has been known since 1962; however,
how the meiotic program is altered to produce diploid eggs while
maintaining heterozygosity has remained unclear. Here it is shown in
parthenogenetic species that meiosis initiates with twice the number
of chromosomes compared to sexual species, and that pairing and
recombination takes place between genetically identical sister
chromosomes instead of between homologues.

a critical limitation in telomerase RNA component (TERC) levels to
restore telomere maintenance and self-renewal, and multiple telomerase
components are targeted by pluripotency-associated transcription factors.

The cells and peripheral representation of sodium taste in mice pp297-301
Mammals are repelled by large concentrations of salts but attracted to
low concentrations of sodium. In mice, the latter behaviour can be
blocked by the ion channel inhibitor amiloride. Here, mice have been
produced lacking the drug's target sodium channel, ENaC, specifically
in taste receptor neurons. It is confirmed that sodium sensing, like
the four other taste modalities (sweet, sour, bitter and umami), is
mediated by a dedicated 'labelled line'.

Peel eased the black Toyota Prius off the M11 and continued on across Essex. Thank God he didn’t have to make this journey regularly like in the old days, before he started doing his programme via ISDN from Peel Acres. Still, it had been fun to visit some of the old watering holes in London. Walters would have enjoyed it. No-one had recognized him. Being dead had its compensations. Heart attack on a walking holiday in Peru? He’d thought no-one would ever believe that, but Pig said they would, and of course she was right. And no-one was going to look for him in the Essex badlands.

Pig would be asleep when he got back, but he’d get up early tomorrow and cook her breakfast. Couldn’t afford to sleep in tomorrow anyway, had to get the March edition of Dandelion Radio online before the weekend. The music was the main thing of course, as always. All those new bands straining to be heard. But it was fun pretending to be all the different DJs, especially the occasional fake Dutch accent. A heck of a lot more fun than working for the BBC, that was for sure. It had just got worse and worse over the years. Home Truths was the killer, nice idea but eventually he just couldn’t take the BBC bullshit any longer, and “death” had been a relief. Dandelion Radio was just about doing what he liked. A bit like the pirate days really, but totally legal. Of course, it didn’t pay, but radio had never been about the money. And no more Top of the Pops bollocks either, although it had paid for the original Peel Acres. Yes, he wished he’d discovered this internet thing years earlier. It might have kept him alive.

It has been one year since I commented on 23andMe’s foray into clinical medicine. I was frankly blown away that such a move would be so blatant without integration of health care practitioners.

After dinner at the CFB Reps Forum last September, Peter Klappa gave us a practical demonstration of how pub quizzes can be used in an educational context. In spite of the hangover next day, I decided that this was still a good idea and that I wanted to try it out on one of my own courses.

In a nail-bitingly close finish (nineteen and a half point to nineteen), AIDS & Co managed to hold off a late push from the Vacant Virologists to unexpectedly claim the confectionery prize. The whole thing was clearly very engaging, and I will certainly be using this format again, although like all such interventions, it clearly needs to be used sparingly to remain effective.

Feedback:

1. Have you done this type of exercise before (if so, when)?
No (3)

2. Was this session useful?
I found it very useful – learnt a lot. I will be using the quizzes on blackboard more since doing questions has proved helpful. Very useful form of revision. I learned more than I expected to from it. It was a nice overview of the past few weeks (and it doesn’t hurt that we had fun doing it).

3. Any other comments?
Can we have a copy of the answers please.
Very enjoyable. Would be nice to have a copy of the Q&As.
[problematic - writing good questions is time consuming and I need to be able to reuse them]

Luc Reid has an interesting article in the latest issue of Clarkesworld Magazine – “Future Brains: Neuroscience Fiction versus Neuroscience Fiction“.

Science fiction has had brains on the brain at least since Dr. Frankenstein installed one in his monster. Over the years science fiction has depicted technologies like mind control (in Star Trek, for example), instant learning (The Matrix), telepathy (Robert Heinlein’s Time for the Stars), and transferring memories and skills (The Dollhouse). While some of these technologies may eventually prove to be possible, others are extremely unlikely to ever work based on what we now know about the brain — because our own minds are much stranger territory than we ever used to imagine they were.

Go check it out if you are interested in the real science behind copying memories, mind control, and telepathy.

WDYTYA 2010

Who Do You Think You Are (WDYTYA) 2010, the world’s largest genealogy conference, was a wonderful success. Like last year, the line at the door started early and stretched for several blocks. But the crowds were definitely larger every day, and the traffic was much heavier on Sunday than in the previous year. Most of the same booths appeared with a few noticeably missing, however.

Early Friday Morning at WDYTYA

The Society of Genealogists (SoG) has posted the handouts from the various lectures at: http://www.sog.org.uk/events/2010show.shtml

Family Tree DNA

Family Tree DNA has attended WDYTYA for the last two years due to the foresight of Geoff Swinfield, a geneticist, well-known at SoG (Society of Genealogists) and Brian Swann, ISOGG’s European Coordinator for England and Wales. In a pub conversation two years ago, Geoff suggested the idea of bringing Family Tree DNA to London’s Who Do You Think You Are conference. Brian put this idea into action and last year was Family Tree DNA’s debut in London. Their success was met with an offer to attend The Gathering in Scotland in July 2009 and a desire to return to WDYTYA this year. This year, Family Tree DNA doubled
the size of its stall as well as its presentation area.

FTDNA Announces New Family Finder Test

This year FTDNA President Bennett Greenspan introduced the company’s new Family Finder test for the first time to the public. This tests the autosomal sections of all the chromosomes to determine matches by cousins on any line of the pedigree chart. FTDNA will not be releasing this test to the US public for another three weeks, and several Brits with whom I spoke were pleased to see they were first.

Learn more about this test at: http://www.familytreedna.com/landing/family-finder.aspx
Frequently Asked Questions (FAQ) provides more details: http://www.familytreedna.com/faq/answers/17.aspx

The various types of DNA tests (Y-chromosome, mitochondria, and Family Finder tests) proved to be very helpful to WDYTYA participants. Each potential customer explained their goals for testing while the FTDNA volunteers help them determine which test best solves their problem. People who were adopted, those wishing to learn if their cousin was really their cousin, those wishing to break through their genealogical brick walls, and even those who were just curious received all the answers to their questions and a recommendation as to which test would help them.

ISOGG Debut

For the first time at this convention, the International Society of Genetic Genealogists (ISOGG) acquired a booth, thanks to Brian Swann. Members from both the UK and USA manned the booth, signing up new ISOGG members as well as giving away free DNA tests to those who qualified. ISOGG members who wished to gain testers for their particular Surname projects offered free tests for males who would qualify with the proper surname. The first test given away was on Friday for Cynthia Wells’ Wells Y-DNA Project. That was followed by someone qualifying for the Doug Miller’s Land Project. He has a second possibility as well. Then others were found for Cynthia’s for Lay Project and for Katherine Borges’McCallum-Macolm Project. A test was taken by a Graves for Kenneth Graves’ Ydna Project. People picked up flyers for Robert Sterry’s Sterry Project and Nancy Kiser’s Phillips Project as they who knew people with that surname. Katherine is pleased that two Fullers who are do not carry the Fullers’ surname are being tested with Family Finder. Much to Katherine’s pleasure, one also has a Lyon connection. The odds of finding attendees with the correct names visiting the booth are remarkable. The offer was deemed a success and will continue next year so be sure to stop by the ISOGG booth and see if your surname is among those the project managers need for their groups.

Fun in the Pub

And there there was sight-seeing and great times in the pubs visiting with all the helpers and genetic genealogy speakers. We sure missed our local pub, however. The Crown and Sceptre, Kensington (now closed) was in the next block from the B & B and had wonderful food! But, this is London and we found a few others!

Kenny, Katherine, Bennett, Debbie

Ann, Emily, Katherine, Johanna (standing), Linda and John

The Players

Last year, four ISOGG (International Society of Genetic Genealogy) members attended from the US, but this year nine went. For the British, last year four attended that all of us knew, but this year there were eight. Doubling these numbers was wonderful and helped greatly with assisting both the FTDNA booth and the ISOGG booth. It was wonderful seeing all the friends from England again.

WDYTYA 2011

Everyone is already looking forward to WDYTYA 2011. Plans are already being made for a return and ISOGG members are even more committed to providing free tests to help their projects. Be sure to stop by the booth to see if your name qualities.

In the US we are excited about the American Version of Who Do You Think You Are on NBC each Friday night in hopes it will renew interest in genealogy. Check your local listings for the time in your area.

See you next year London!

Update: This post was an attempt to improve academic input into REF by establishing a curated list of the “best” journals to publish in. As is the house style for this blog, it was written in a “humorous” style as befits this medium. In an email message from a colleague, I have been informed that my clumsy attempts at humour have done “serious damage has been done to what was, we thought, a productive relationship“. If I have caused any offence by this post, I apologize unreservedly. I have also been asked to take this post down, which I do not intend to do. I hope that the discussions arising from this post will make it possible to achieve the reasons for posting it here.

At the University of Leicester, we have these strange beings called Information Librarians. For many years, this confused me, because I though that all librarians were information librarians. But no, it turns out that most librarians are misinformation librarians, and the only librarian you can trust is a University of Leicester Information Librarian. Having figured that out, I need to ask a question. What the heck are Information Librarians for? To try to figure that out, I’m going to pose a hypothesis then test it.

The role of the Information Librarian is to help me find the information I need to do my job.

There it is, for better or for worse. So let’s test it. What information do I need to do my job? You may have heard of something called the Research Excellence Framework (REF). Personally, I wish the REF and the people that invented it would crawl into a pox-ridden hole and die, but I suspect that’s not going to happen. The bean counters love REF, and if there’s one thing we’re not short of in higher education it’s bean counters. REF is going to work mainly on the spurious measurement of journal impact factors. (They say it’s not. They say it hasn’t been decided yet. They say it may never happen. They lie.) So I’m not able to publish my research in open access journals where I’d like to, instead I have to try to maximize my impact factor score. What information do I need to do that? I need an accurate, up to date list of the impact factors of all the journals where I might publish my research. I need the list maintained, curated, updated, stroked and given a saucer of milk. Do I currently have such a list? No. What are Information Librarians for?
