Weird Science – Watch and Learn

Outside it is not much to look at, little more than a discoloured rock dredged up from the sea floor. But an x-ray scan of the object, actually a pocket watch recovered from a 17th century shipwreck, has revealed that the internal mechanism has been perfectly preserved. The computer aided tomography system used was sensitive enough to pick out the tiniest details, included the engraved name of the master watchmaker, one Niccholas Higginson of Westminster, London (Gizmodo).

As if more proof were needed that they don’t build them like they used to, a UK group has started collecting donations to build the first fully working version of Babbage’s “Analytical Engine”. The original design, dating from 1837, was never completed, possibly due to a combination of the strict engineering tolerances needed and Babbage’s notoriously prickly temperament. If the final machine works as advertised, it will be very strong confirmation of the claim that Babbage designed the first general purpose, programmable computer (BBC News).

Meanwhile, in Slovenia, Borut Povse and his team are busy teaching a modern descendant of Babbage’s design to hit people. Somehow Povse has convinced six volunteers to let an industrial robot hit them on the arm with various sharp or blunt implements in an effort to determine how much pain each blow causes. Obviously this has a beneficial use in that robots can be programmed not to exceed certain levels of force near a human obstacle, but will also be of immense interest to the machines during any future robot uprising (New Scientist).

Another robot out to supplant humans is HRP-4, a gynoid (female android), that has learnt to sing by copying the inflection and expressions of a human performer, right down to the breathing. The hope is to make robots behave in a more convincingly natural way, and so overcome the so called ‘uncanny valley’. From the video, it looks like they’ve still got a way to go (Daily Mail).

Design a New Periodic Table

When you think of the periodic table, a bunch of blocks may pop into your mind. It's time to revise your thinking, and you may be the next to invent a new design. I like this galaxy model.


This arrow shaped one has even more information you really don't see in the lego version.



Yet another try in a circular pattern.



Here's a link to a story from the New York Times about developing a new shape.

I especially like the question marks. Does this mean new elements -- maybe discovered by you?

House Fire Caused By… Spontaneous Combustion!?

Spontaneous combustion is a type of combustion which occurs without an external ignition source. It's also fairly uncommon. But this summer, in Little Rock, Arkansas, an insurance claims adjuster concluded that the fire that caused $20,000 worth of damage to the Duncan's home was a classic case. Brian Duncan said a flowerpot on the porch was the culprit. You can read the full article here.

The Return of Doctor X

Humphrey Bogart regarded this as his biggest dog of a film. He plays a mad scientist who went to the electric chair, died, was revived with "synthetic blood," then had to subsist by draining the blood of others.

And here's the weirdest thing: almost every scene in this trailer is an outtake, not seen in the actual film! I wonder if viewers of the era felt ripped off.

'Nuff said!

Weird Science – Invention Is The Mother Of Necessity

Build a better mousetrap, it is said, and the world will beat a path to your door. The implication being that there are some problems which are just crying out for a solution. And then there are the solutions crying out for a problem - those inventions that, while inspired, are just a tad “out there”. It is this later category I shall be celebrating today.

First up, how clean is your cow? This age old problem has nagged at the minds of farmers down the ages, are their cows clean enough? And why isn’t there an easier way to clean cows? Well these merchants of the soil need worry no more thanks to a Swedish company that has developed the fully automated “cow wash”. Supposedly improving the health and yield of cows that use it, the cow wash uses a free swinging revolving brush to groom the cows while simultaneously stimulating their circulation. Apparently the cows enjoy using it and the makers DeLaval have sold over 30,000 in Sweden alone (Daily Mail).

Bigwigs in the US military will also soon be able to sleep sounder in the knowledge that the men under their command are safely in their underpants. We’re not just talking about any undies though, these have been specially designed by University of California professor Joseph Wang. Not only will his techno-trunks monitor the vitals of the personnel wearing them, they can even administer painkillers or antibiotics as the situation demands (Post Chronicle).

And if your pants don’t save you, at least your modesty will be preserved when you are taken to hospital, all thanks to the University of Montreal. For it is from that fine establishment’s School of Industrial Design that our next invention hails, a hospital gown that isn’t quite so revealing. The DUO gown is the brainchild of Noemie Marquis and Denyse Roy and consists of two overlapping panels, front and back, that is easy to put on and requires no fasteners making life simpler for both patients and staff (Medical News Today).

Meanwhile British scientists have been working on an altogether sterner cover. Nicknamed “bullet-proof custard” by its inventors, Bristol based BAE systems have developed a liquid armour consisting of layers of Kevlar combined with a secret “shear-thickening” liquid that hardens as force is applied. The company’s eventual aim is to produce lighter, more-flexible body armour for the military (BBC News).

Allow Me To Make A Point

Acupuncture is the procedure of inserting needles into various points on the body, used in most cases to eliminate chronic pain. But as with most ancient medical practices, there is heavy debate as to the validity of the science. And in all my reading on the subject, I have never encountered a claim like the one being made by Pham Thi Hong of Vietnam. Ms. Hong says she can detect whether or not a man is a virgin - it is a combination of checking the man's pulse and looking for a tiny red spot behind his ear. Apparently the spot will only disappear after heterosexual intercourse, and is not affected by gay sex or masturbation. But even though I doubt Ms. Hong's methods, she has made a name for herself. While treating a young man convicted of gang rape, she discovered the spot behind his ear and was convinced he was innocent. Her extremely persuasive campaign lead to the case being re-examined and investigators determined that the original case was flawed. The man was released from prison in January. Of course this has lead to a surge of appeals from other convicted rapists for Ms. Hong to examine them and clear their name. And while many would say this is proof that her method has merit, the underlying point is that the man was released from prison because the original investigation was erroneous. It raises an interesting question, though. How many of you read this and went to see if you have a tiny red spot behind your ear?

Weird Science – From Whales To Sails

Sperm whales are among the biggest living things on the planet and, surprisingly for these gentle giants, once must have been among the most fearsome. Palaeontologists working in Peru have uncovered the remains of an extinct long lost relative of today’s sperm whale that had 30-40 cm long teeth in both jaws (the modern form has much smaller teeth in the lower jaw only). With jaws more closely resembling those of a killer whale than its thrust/suction feeding relative, scientists believe the newly named Leviathan melvillei was a 15 m long hunter of large prey, probably other whales. Its size, jaws and undoubted intelligence would have made this marine monster more than a match for the giant shark Megalodon with which it shared its home (Science [article], Nature [paper]).

Sperm whales are still the largest animal ever to have teeth, but today their diet consists mostly of squid – including the infamous giant squid – and therein lies a problem. Whereas most land dwelling creatures live on plant material, or some juicy meaty derivative thereof, and hence are essentially “carbon-neutral”, marine animals from penguins to whales feast upon carbon that was probably sequestered in the oceans hundreds if not thousands of years ago, or has weathered out of rocks that are millions of years old. One upshot of this is that carbon dating is notoriously inaccurate on marine organisms, what scientists call the “reservoir effect”, another is that unlike water breathers such as fish, who return this carbon to the oceans, air breathing animals like whales will release this carbon to the atmosphere as CO2 and so contribute to global warming. However in new research published by the Royal Society of London, researchers have calculated that whales have actually offset their carbon emissions with emissions of another kind. Whale poop is iron rich and comparatively liquid, hence returns the excess iron in the whale’s diet back to the oceans in a form that is readily usable by phytoplankton. The team, led by Trish Lavery of Flinders University in Australia, estimate that sperm whales are responsible for removing 200,000 more tonnes of carbon from the atmosphere annually than they actually emit (Royal Society).

But it’s not all good news for the tree-huggers for while whales might be a boon in the fight against climate change, their free-range, organic farming practices of preference are almost certainly not. In a paper published by the National Academy of Sciences, Jennifer Burney of Stanford University and her colleagues have found that intensive farming is by far the most land and carbon efficient method of agriculture. Because agricultural land use is a major contributor to global warming, increasing the yields from farmland, and thereby reducing the amount of land farmed, strongly outweighed the extra carbon emissions of the intensive farming needed to achieve this. Doing the sums on farm outputs since 1961, the team found that increased yields have produced the same as cultivating an additional area the size of Russia at 1961 levels, which would have led to the release of 590 billion more tonnes of CO2, equal to about a third of all man-made emissions since the industrial revolution (PNAS).

And modern farming may be coming to our rescue in another way, as a source of cheap batteries. Almost since Ben Franklin gave up kite-flying, kids in schools the world over have been making batteries out of apples or a potatoes. Now a trio of researchers from the Hebrew University of Jerusalem, led by Alex Goldberg, have found a way to turn these vegetable power sources from classroom curiosities into a viable product. What’s more amazing is the method they discovered to generate a tenfold increase the output of their potato power-pack, they boil the potato first. How did no-one think of this before (AIP)?

Another new idea, albeit a less welcome one, is that one should prosecute scientists for not knowing everything. At least that seems to be the approach taken by the public prosecutors of the Italian city of L’Aquilla, which last year was hit unexpectedly by an earthquake that killed over 300 people and injured 1600 more. The defendants include the head of Italy’s National Institute of Geophysics and the director of the National Earthquake Center along with four other equally prominent scientists and Bernardo De Bernardinis then deputy head of the Civil Protection Agency, who together are looking at being tried for manslaughter for not alerting the population to the imminent disaster at a meeting held one week before the quake struck. It was Bernardinis, a government official, who claimed in a press conference held immediately after the meeting that the scientists had said there was “no danger”, despite the minutes of the meeting clearly showing that at no time was the chance of a major shock ever ruled out (Nature).

Weird Animals - Och Aye The Roo!

The week saw the publication of the 2010 Eden Wildlife Report, which tracks the numbers of foreign species introduced to the UK over the past century. Compiled by Dr. Toni Bunnell and a team from the University of Hull, the report mentions wallabies thriving in Scotland, scorpions setting up home in Kent and aardvarks that have somehow emigrated from Brazil to Cumbria (Telegraph).

Of course, this won’t be news to one member of Britain’s thriving rod-fishing community, who this week caught a piranha in his local pond (Guardian).

Another place you might not expect to see exotic creatures is on your lunch menu, but that didn’t stop one restaurant owner in Mesa, AZ from putting “lion burgers” on the menu to celebrate soccer’s World Cup. Cameron Selogie of the Il Vinaio makes his “mane course” with genuine lion meat imported from South Africa, earning him the ire of local animal rights groups and several death threats, but not a reprimand from health officials. According to an FDA spokesman serving lion meat is perfectly legal, as long as it’s not roar (Scotsman).

Slightly luckier than the lions, one cat who has fallen on his feet is Oscar, a housecat from the Isle of Jersey in the UK, widely billed as the “bionic cat” after successfully receiving two artificial hind legs to replace the ones he lost in an altercation with a combine harvester (BBC News).

You might think pitting a rodent like mammal against a 12 tonne Triceratops makes for an equally one-sided match up, but evidence emerged recently that our primitive ancestors occasionally feasted upon dinosaurs. Seventy-five million year old “gnaw marks” of a kind characteristic of early mammals, and belonging to a creature not much bigger than a squirrel, have been found on the fossil bones both of Tricerotops and the crocodile-like predator Champsosaurus (LiveScience).

Sadly today the nearest we get to dinosaur flesh is turkey or chicken, but not all birds were prized solely for their meat. The huia bird of New Zealand for example, was once used to make the feathered head-dresses of Maori chiefs, until predation from accidentally introduced species drove it to extinction around 1907. But if the bird has gone its feathers have not, and one recently became the most expensive feather ever when it sold at auction for NZ$8000, i.e. $4000 American (Telegraph).

Good News!

For those of us who are too tired to try and get back into shape (if we ever were in shape... I think I was in shape in high school twenty-some years ago). A recent study published in the journal Body Image claims that chubby men are as attractive as men with six-packs. The University of Queensland, in Australia, had participants rate mock-up advertisements for jeans, skin-care products and cologne featuring muscular male models and average looking men. Neither the men or the women in the study responded more favorably towards the muscular models. You can read more about the study here.

Integrated Luminosity doubled at CERN

May 17th twitter feed from CERN:

Another good weekend for the LHC saw the integrated luminosity for 2010 double. This is a measure of the total number of collisions.
8:04 AM May 17th

The previous post explains they are up to half a billion collisions.

Adding the tally from last weekend's runs, the LHC experiments have observed around half a billion collisions to date.
7:03 AM May 12th

Here's the link for the CERN twitter feed.

http://twitter.com/cern/

Here's another citation about the possible discovery of the decay of a "Strange beauty particle".

http://lhcb-public.web.cern.ch/lhcb-public/

While everyone is worried about the CERN super-collider causing a black-hole, you have to admit that some pretty cool simulations have been created.

For your entertainment an excellent extreme black hole example, which happens to have CERN at its beginning.



Still not as exciting as siphons.
