Solar System: Things To Know This Week

If this Tibetan padlock looks massive that is because it is! And it has not one but THREE equally ginormous keys to open it! It is definitely a very intriguing padlock and indeed something of a puzzle as all three keys must be fitted simultaneously for it to open. There is one lock at the top underneath a panel, another on the side, and a third under a hinged panel on the back. Quite impressive!

We think it dates from the late nineteenth or early twentieth century and was purchased for the museum by Emslie Horniman, who was the son of our founder Frederick Horniman.

Neuro chip records brain cell activity at higher resolution

Brain functions are controlled by millions of brain cells. However, in order to understand how the brain controls functions, such as simple reflexes or learning and memory, we must be able to record the activity of large networks and groups of neurons. Conventional methods have allowed scientists to record the activity of neurons for minutes, but a new technology, developed by University of Calgary researchers, known as a bionic hybrid neuro chip, is able to record activity in animal brain cells for weeks at a much higher resolution. The technological advancement was published in the journal Scientific Reports.

“These chips are 15 times more sensitive than conventional neuro chips,” says Naweed Syed, PhD, scientific director of the University of Calgary, Cumming School of Medicine’s Alberta Children’s Hospital Research Institute, member of the Hotchkiss Brain Institute and senior author on the study. “This allows brain cell signals to be amplified more easily and to see real time recordings of brain cell activity at a resolution that has never been achieved before.”

The development of this technology will allow researchers to investigate and understand in greater depth, in animal models, the origins of neurological diseases and conditions such as epilepsy, as well as other cognitive functions such as learning and memory.

“Recording this activity over a long period of time allows you to see changes that occur over time, in the activity itself,” says Pierre Wijdenes, a PhD student in the Biomedical Engineering Graduate Program and the study’s first author. “This helps to understand why certain neurons form connections with each other and why others won’t.”

The cross-faculty team created the chip to mimic the natural biological contact between brain cells, essentially tricking the brain cells into believing that they are connecting with other brain cells. As a result, the cells immediately connect with the chip, thereby allowing researchers to view and record the two-way communication that would go on between two normal functioning brain cells.

“We simulated what Mother Nature does in nature and provided brain cells with an environment where they feel as if they are at home,” says Syed. “This has allowed us to increase the sensitivity of our readings and help neurons build a long-term relationship with our electronic chip.”

While the chip is currently used to analyze animal brain cells, this increased resolution and the ability to make long-term recordings is bringing the technology one step closer to being effective in the recording of human brain cell activity.

“Human brain cell signals are smaller and therefore require more sensitive electronic tools to be designed to pick up the signals,” says Colin Dalton, adjunct professor in the Department of Electrical and Computer Engineering at the Schulich School of Engineering and a co-author on this study. Dalton is also the facility manager of the University of Calgary’s Advanced Micro/nanosystems Integration Facility (AMIF), where the chips were designed and fabricated.

Researchers hope the technology will one day be used as a tool to bring personalized therapeutic options to patients facing neurological disease.

Happy almost birthday, Shakespeare! Or should I say Bard-thday? Recently, in honour of the 400th anniversary of William Shakespeare’s death (conveniently for celebratory purposes, he was born on April 23 1564 and died on the same day in 1616), I was given the incredible opportunity to have a private audience to go through the University of Glasgow’s copy of the First Folio, page by page. I’ve written a short article for the University Library’s blog, which you can find here, but I wanted to share some other images on my own blog that I didn’t have room for on the official post!

The University of Glasgow’s First Folio (more properly known as Mr. William Shakespeare’s Comedies, Histories, & Tragedies) is able to tell so many more stories than those of the plays contained in its pages- of the history of the antiquarian book trade, of the printing practices of the Renaissance, of book ownership and value. Rest assured, you’ll probably be seeing posts from me in the future about all of these things, as well as the typographical ornaments used in the book, which I found fascinating. The University’s Folio is particularly interesting due to the notations by past owners, including one who had apparently seen at least one of the original Chamberlain’s Men “By eyewittnesse”. But my favourite bit of the later additions is the morbid little poem on the reverse of one of the flyleaves: “Pitty it is the fam’d Shakespeare/ Shall ever want his chin or haire.”

The Fibonacci sequence can help you quickly convert between miles and kilometers

The Fibonacci sequence is a series of numbers where every new number is the sum of the two previous ones in the series.

1, 1, 2, 3, 5, 8, 13, 21, etc. The next number would be 13 + 21 = 34.

Here’s the thing: 5 mi = 8 km. 8 mi = 13 km. 13 mi = 21 km, and so on.

Edit: You can also do this with multiples of these numbers (e.g. 5*10 = 8*10, 50 mi = 80 km). If you’ve got an odd number that doesn’t fit in the sequence, you can also just round to the nearest Fibonacci number and compensate for this in the answer. E.g. 70 mi ≈ 80 mi. 80 mi = 130 km. Subtract a small value like 15 km to compensate for the rounding, and the end result is 115 km.

This works because the Fibonacci sequence increases following the golden ratio (1:1.618). The ratio between miles and km is 1:1.609, or very, very close to the golden ratio. Hence, the Fibonacci sequence provides very good approximations when converting between km and miles.

No. 2 Construction Battalion

Fighting for a country that didn’t want them.

On March 25 1917, Canada’s first and only black military unit left Halifax harbor for the Western Front. Six hundred soldiers, mostly from Nova Scotia, formed up as No. 2 Construction Battalion. Many had been trying to enlist since 1914,  but winning this privilege had been an up-hill fight: for two years military authorities had turned down black recruits, telling them “This is a white man’s war.”

Finally, in 1916, Canada allowed black recruits entry into a segregated united of laborers. An additional 165 African-Americans crossed the border to join them, creating a full complement of 600 men. Winning the struggle to join up hardly ended discrimination. Except for the reverend, all officers were white, and even when they went to board their transport ship on March 25 the captain initially refused to let them on, saying that he would not let them travel on the same vessel as white soldiers.

The recruits hoped to be allowed to fight when they reached France, but instead the Canadian Expediotnary Force immediately downgraded them from a battalion to a company and assigned them to fell trees and prepare positions for white soldiers. They were not ever even issued with rifles. Their work was tedious and demoralizing, and many considered themselves failures even as they suffered casualties from artillery shells and poison gas.

The unit returned to Canada in 1919, but received no fanfare upon arrival. Much like America’s black soldiers, they returned to a country that did not value them or their sacrifice and actively oppressed their rights. Most of these veterans returned to poverty and unemployment. When they finally had their first reunion in 1982, only nine could attend from twenty known survivors. Their legacy and sacrifice has been revived since then. Although very few men were allowed the chance to serve, they began the first crack in the Canadian military’s institutionalized racism.

George Michael was 23 when he sat for this interview, which has never been broadcast before.

He had just embarked on his solo career after leaving Wham!. During the conversation, George Michael talks about his sexuality and shedding his pop-ballad persona ala Careless Whisper. He reflects on the power of his fame, as he recalls the historical trip Wham! took to play in communist-China in 1985.

Don’t play, play - Singlish is studied around the globe

Blogger Wendy Cheng’s Web video series Xiaxue’s Guide To Life and Jack Neo’s Ah Boys To Men film franchise are well-known shows among Singaporeans. For one thing, they are filled with colloquial terms, local references and copious doses of Singlish terms such as “lah” and “lor”.

But they are not merely for entertainment. In recent years, such shows have found a place in universities around the world, where linguists draw on dialogues used in these local productions to introduce to undergraduates and postgraduate students how Singlish has become a unique variety of the English language.

This comes even as concerns have been raised over how Singlish could impede the use of standard English here.

From Italy and Germany to Japan, at least seven universities around the world have used Singlish as a case study in linguistics courses over the past decade. This is on top of more than 40 academics outside of Singapore - some of whom were previously based here - who have written books or papers on Singlish as part of their research.

A whole lot of books

In 1610, after successfully rebuilding, reopening and firmly establishing the Bodleian Library, Sir Thomas Bodley made it his new goal to ensure the library’s long-term relevance. He forged an agreement with the Stationers’ Company that saw his library receive one copy of everything printed under royal license. This would guarantee that the Bodleian would continue to be at the cutting edge of literature and librarianship.

And this was when the Bodleian became, by effect, the first Legal Deposit library in the UK. From 1662, the notions were solidified and the Royal Library and the University Library of Cambridge were also party to the same privileges. Until the establishment of the British Library in 1753, the university libraries of Oxford and Cambridge - especially the Bodleian Library, which had enjoyed the legal deposit privilege the longest – served as the de facto national libraries of the United Kingdom.

But what’s the current state of Legal Deposit at the Bodleian? And, as @LowlandsLady asked us on Twitter, might it ever feel like a curse to have this multitude of books rolling into the library?

There’s nobody better to answer these questions than Jackie Raw, Head of Legal Deposit Operations in our Collections Management department. From this point on, this Tumblr post belongs to Jackie.

The Legal Deposit Libraries Act 2003 obliges publishers to deposit, at their own cost, one copy of every printed publication that is published or distributed in the UK with the British Library and, upon request, with up to five other Legal Deposit Libraries of which the Bodleian is one.

These Legal Deposit Libraries seek to ensure that the UK published output is preserved for posterity. To do this the requesting libraries together use the Agency for the Legal Deposit Libraries. The Agency makes claims for titles on our behalf and, on receipt, these are recorded and distributed weekly to the libraries. By collaborating the Legal Deposit Libraries seek to develop and co-ordinate national coverage and preservation of, and access to, publications acquired by legal deposit.

A random selection of books arriving by Legal Deposit.

While the Legal Deposit system has existed in various forms since 1662, the reformed Act in 2003 extended the provision for printed material to cover non-print works. This brings new and emerging publishing media under its scope. The Regulations for this came into force in April 2013. We now have the opportunity to add e-books, e-journals, digital maps and digital music scores to our collections and to harvest and archive content from UK-published material on UK websites under the new legislation.

Again the libraries are working together to ensure coverage. The benefits of holding a collection of over 12 million physical items, much of which has been deposited under Legal Deposit, and a growing digital collection cannot be overstated.

A recent count of books arriving daily at the Bodleian Libraries.

Legal Deposit ensures the nation’s heritage is collected systematically and preserved for posterity. It supports and advances the teaching and research activities of the University of Oxford and national and international scholarship more widely by collecting, recording and making available this material and it provides, in a cost-effective way, access to a wide range of publications many of which are unlikely to be found outside of the Legal Deposit system.

However, it is also a responsibility.

Clearly there can be pressures on space, storage and transportation. There are staff levels and processing costs to consider and issues around funding limitations. On the other hand there is provision within the Act to allow libraries, other than the British Library, to be selective in what we acquire. So, by consulting and collaborating we aim to ensure as complete coverage as possible within resourcing limits without overburdening any one library with the rate at which our collections are growing.
