Home Engineering: Dialysis machine

A baby dying from kidney failure was saved when her doctor designed and built her a dialysis machine from scratch in his garage.
…
The job of the kidneys is to ‘clean’ the blood, and if they fail, a dialysis machine can do this job instead.
…
However, Dr Coulthard, together with senior children’s kidney nurse Jean Crosier, devised a smaller version, then built it away from the hospital. Millie was connected to the machine over a seven day period, allowing her own kidneys to recover.

Rebecca, from Middlesbrough, said: “It was a green metal box with a few paint marks on it with quite a few wires coming out of it into my daughter – it didn’t look like a normal NHS one.
…
The machine is still in use, helping babies in similar circumstances to Millie, but Dr Coulthard told the Newcastle Journal newspaper that an official version was needed. “This machine is only being used on the tiniest, earliest babies where there is nothing else that can be done.

“But if we had a machine that we could use much more freely, then we would be able to deal with many more babies and have a much greater chance of saving lives.”

Kids Need Adventurous Play

A survey commissioned by Play England for Playday found a change in the places where children and young people today experience adventurous and challenging play. As children, 70% of adults enjoyed most of their adventures in natural outdoor environments. This compares with only 29% of children today as both the space and the freedom to roam has dramatically declined in recent years. Today, children’s experiences of adventure are confined to designated areas such as playgrounds (56%), their homes (48%) or theme parks (44%).

‘Playing is an essential part of growing up,’ said Adrian Voce, Director of Play England. ‘Starting from their earliest play experiences, children both need and want to push their boundaries in order to explore their limits and develop their abilities. Children would never learn to walk, climb stairs or ride a bicycle unless they were strongly motivated to respond to challenges – but we must accept that these things inevitably involve an element risk.

‘Adventurous play that both challenges and excites children helps instill critical life skills. Constantly wrapping children in cotton wool can leave them ill equipped to deal with stressful or challenging situations they might encounter later in life.’

2 Mysterious Species in the UK

Plane Bug - UK

Mystery insect found in Museum garden

This mystery bug has not been seen in the UK before and has made the Natural History Museum’s Wildlife Garden its home. The tiny bug is baffling insect experts at the Museum who are still trying to identify the mystery newcomer. The almond-shaped bug is red and black and about the size of a grain of rice
…
Experts checked the new bug with those in the Museum’s national insect collection of more than 28 million specimens. Amazingly, there is no exact match.
…
The bug closely resembles the fairly rare species Arocatus roeselii, which is usually found in central Europe. However, the roeselii bugs are brighter red than this new bug and they are usually associated with alder trees rather than plane trees.

However, the National Museum in Prague discovered an exact match to the mystery bug in their collections – an insect that was found in Nice and is classified as Arocatus roeselii. ‘There are two possible explanations,’ explains Barclay. ‘That the bug is roeselii and by switching to feed on the plane trees it could suddenly become more abundant, successful and invasive. The other possibility is that the insect in our grounds may not be roeselii at all.’

The Museum is working with international colleagues to analyse the bug’s body shape, form and DNA to see whether it is a newly discovered species or if it is in fact Arocatus roeselii.

Here is a green bug from my trip to Clifton Gorge Nature Preserve that is probably easier to identify. Or how about this insect from the Forest Glen Preserve, Illinois. Or how about this one at Our Lady of Gethsemani Abbey, in Kentucky.

Nearly Waterless Washing Machine

Professor Stephen Burkinshaw, Chair of Textile Chemistry at the University of Leeds, has created a nearly waterless washing machine. Xeros ltd. has been created to commercialize products based on this system (both for home use and for solvent-based commercial garment cleaning). Given the predicted trouble for supplies of freshwater technology that can reduce water use will be very useful.

Virtually waterless washing machine heralds cleaning revolution

Researchers at the University of Leeds have developed a new way of cleaning clothes using less than 2% of the water and energy of a conventional washing machine.
…
A range of tests, carried out according to worldwide industry protocols to prove the technology performs to the high standards expected in the cleaning industry, show the process can remove virtually all types of everyday stains as effectively as existing processes whilst leaving clothes as fresh as normal washing. In addition, the clothes emerge from the process almost dry, reducing the need for tumble-dryers.

Cloned Immune Cells Clear Patient’s Cancer

Cloned immune cells cleared patient’s cancer

A patient whose skin cancer had spread throughout his body has been given the all-clear after being injected with billions of his own immune cells. Tests revealed that the 52-year-old man’s tumours, which spread from his skin to his lung and groin, vanished within two months of having the treatment, and had not returned two years later.

Doctors attempted the experimental therapy as part of a clinical trial after the man’s cancer failed to respond to conventional treatments.

The man is the first to benefit from the new technique, which uses cloning to produce billions of copies of a patient’s immune cells. When they are injected into the body they attack the cancer and force it into remission.

There are many more wonderful announcements than wonderful solutions that live up to the hope provided by the announcement. Still this is one in the long line of potentially wonderful treatments. If it turns out to be successful the whole world will benefit which is an example of why I am thankful so many countries are investing in science and technology.

False Teeth For Cats

False Teeth For Cats! What Next?

A team of eight British college students, calling themselves Fangs A Lot, have created the first false tooth for a cat and set up a business, Animal Solutions, to market false teeth for cats, dogs, and other animals. The group and its prototype false cat tooth have made it to the finals of the Ideas Igloo Roadshow, an invention contest for college students sponsored by Britain’s Make Your Mark Campaign and Microsoft, UK.

False teeth for cats may sound ridiculous, but they could be a solution to a serious problem for cats. Cats have notoriously bad dental problems. Cat owners seldom brush their cats’ teeth or scrape the surfaces of the teeth to remove plaque. By the time a cat is 3 or 4 years old, she may already have periodontal disease that can lead to tooth loss. Tooth loss may also come about as a result of tooth breakage, particularly in the canine teeth.

Students Create “Disappearing” Nail Polish

‘Vanishing’ colour gives schoolgirls chance to beat ban on nail varnish

A nail varnish that “vanishes” has been developed by a group of school pupils – offering girls the chance to beat bans on makeup. The nail colour is a vivid red outdoors – but inside it transforms to a much paler shade which can hardly be seen.

The dramatic change is caused by a chemical reaction between the varnish and the ultraviolet light in natural sunlight. The polish was devised by pupils from Albion High School, Salford, who thought the “vanishing” colour may help them beat the school’s ban on nail polish.
…
They came up with the idea while working on an enterprise project with Paul Haywood and Sam Ingleson from Salford University’s school of art and design.

Not exactly what I would create but it is great to see students using scientific thought to find solutions they desire.

Ranking Universities Worldwide

The Webometrics Ranking of World Universities provides another estimate of the top universities. The methodology is far ideal however I still find it interesting. The various attempts to rank schools can provide a general idea of impact of various institutions (though the measures are fairly crude). Still a sensible picture (especially at the country level) can emerge. And the various rankings should be a able to track shifts in the most influential institutions and relative country strength over time. How quickly those rankings track changes will vary depending on the measures used. I would imagine most will lag the “real” changes as it is easy to imagine many measures that would lag. Still, as I have said before, I expect the USA will lose in relative ranking compared to China, India, Japan, Singapore, Mexico…

The ranking methodology used here weighed rankings in: Jiao Tong academic rankings, Essential Science Indicators, Google Scholar, Alexa (a measure of web site visits to universities) and The Times Higher World University Rankings.

Country representation of the top universities (number of top schools in each country):

location	Webometrics Top 100	Jiao Tong Top 101	% of World Population	% of World GDP*
USA	53	54	4.6%	30.4%
Germany	10	5	1.3	6.3
Canada	8	4	0.5	2.5
United Kingdom	6	10	0.9	5.0
Australia	3	2	0.3	1.6
Japan	1	6	2.0	10.3
The rest of Europe	16	13
Brazil	1	0	2.8	1.8
Mexico	1	0	1.6	1.7
Israel	0	1	0.1	0.3
