Chimps and humans have the same number of hairs. Human hair is just much finer.

A chimp has no more individual hairs than a human. While the texture of the hair on the human body is much finer and less visible to the naked eye, it is actually about the same amount of fur as on a chimp. It is thought that perhaps humans originally had a thicker coat of fur that may have served as protection, but it eventually receded over time as it began to be less necessary for survival. Evolutionary theories as to why humans’ body hair became finer include making it easier to sweat, as well as to make parasites and lice less of a nuisance.

More about chimpanzees and humans:

  • It is estimated that approximately 97% of human genes are the same as chimps.
  • Scientists in the 1970s were able to teach a chimpanzee sign language, which included 125 words and the ability to express desires.
  • Chimps are estimated to be between two to three times stronger per pound than humans; therefore, a human the same size as a chimp could exercise for 12 hours a day and still not approach the same level of strength.

Artist creates world's smallest sculpture only for it to be accidentally CRUSHED as it was being photographed





An artist has created the world's smallest sculpture only for it to be accidentally crushed by a finger while being photographed.
Jonty Hurwitz's creations are so tiny they can rest on a human hair and are the same size of an ant's head.
Having spent months working on the pieces, the 45-year-old from Chichester, West Sussex, took them to a photographer to have them pictured under a microscope.

But within minutes his work had been destroyed by the stroke of the lab technician's finger.

I went off to have the original sculptures photographed so I found a laboratory with an electron microscope and the photographic technology,' said Mr Hurwitz.
'The technician went to change the orientation and then for the next half an hour we were looking for the piece through the lens.

'Eventually I noticed there was a fingerprint exactly where the sculpture used to be and I was like "man you have just destroyed the smallest art pieces" ever made - I slightly freaked out.'

The sculptures are less than 1mm tall and are produced via a process called nano-painting.

They are too small to be seen with the naked eye so must be viewed and photographed under a microscope.

Mr Hurwitz uses a 3D printing technology to produce them.

Describing the process on his website, he said: 'The structure is created using a ground-breaking new 3D printing technology and a technique called Multiphoton Lithography.





The artist from Chichester, West Sussex, described his work as a combination of 'art and Quantum Physics'

'Ultimately these works are created using the physical phenomenon of two photon absorption. Art, literally created with Quantum Physics.


'This two photon absorption occurs only at the tiny focal point - basically a tiny 3D pixel (called a Voxel).

'The sculpture is then moved along fractionally by a computer controlled process and the next pixel is created. Slowly, over hours and hours the entire sculpture is assembled pixel by pixel and layer by layer.'

What is nanopaint ?

Nanopaint is a coating that can modify the properties of a surface or substance according to user-defined parameters. Like ordinary paint, nanopaint is applied as a liquid and then hardens. The liquid contains a suspension of microscopic particles called nanotube s that alter their behavior as external conditions change or when a specific command is given. Nanopaint is in the research-and-development phase.

Engineers have produced a prototype nanopaint that can block RF (radio frequency) fields in much the same way as a metal, such as copper, can do. When applied to the interior walls of a building, the material can selectively pass or impede signals to and from cell phones, portable radios or other wireless devices.

Potential applications of nanopaint abound. One especially interesting idea is the use of nanopaint on the exteriors of buildings to alter their infrared (IR) reflecting or absorbing properties depending on external conditions. This could improve energy efficiency by helping structures absorb thermal energy on cool but sunny days, reflect it on hot days, retain thermal energy on cold nights and radiate it away on warm nights. Specialized nanopaints might perform an almost endless number of other functions, such as:

  • Block cell phone signals in inappropriate environments, such as theaters, hospitals and funerals.
  • Give glass the ability to become more or less opaque as desired.
  • Give the surfaces of motor vehicles or industrial machines the ability to repair themselves when damaged.
  • Allow the textures of surfaces to be altered at will.
  • Discourage the growth of pathogens such as bacteria or viruses.
  • Repel or neutralize toxic chemicals, acids or other corrosive agents.


The sculptures are believed to be the smallest representation of the human form ever created by man.

How to build a skyscraper in NINETEEN DAYS:

Theres some good tech here.

Time-lapse shows how Chinese firm builds 57-storey block at a rate of three floors a day

  • The building has 800 apartments and enough office space for 4,000 people
  • It was originally planned to be built up to a height of 220 storeys
  • However, it was cut down because of concern it was too close to an airport
  • Amazing time-lapse video shows the skyscraper rising up in seconds

Gravitational Casimir Effect

It might be possible to use superconductors to detect gravitons.


2 weeks ago we were finding out about light being detected as a particle and a wave (top of this page ) now possibly gravity too.


"the existence of gravitons would show that gravity has a quantum nature, capable of behaving as both a particle and wave"

On The Highway To Hell \m/
I've got one that nobody ever knows when I mention it.

Fact: One out of every four animals on Earth is a beetle.

Beetles are the largest group of living organisms known to science. Even with plants included in the count, one in every five known organisms is a beetle. Scientists have described over 350,000 species of beetles, with many more still undiscovered, undoubtedly. By some estimates, there may be as many as 3 million beetle species living on the planet. The order Coleoptera is the largest order in the entire animal kingdom.

Sort of begs the question, "Is God a beetle?". Why would he/she/it create so many different beetles, and so few of all the other living things? Not that I'm even religious, or necessarily believe in higher powers of any sort. But from a philosophical perspective.

The dawn of DUNE - http://www.symmetrymagazine.org/article/march-2015/the-dawn-of-dune

The neutrino experiment formerly known as LBNE has transformed. Since January, its collaboration has gained about 50 new member institutions, elected two new spokespersons and chosen a new name: Deep Underground Neutrino Experiment, or DUNE.

The proposed experiment will be the most powerful tool in the world for studying hard-to-catch particles called neutrinos. It will span 800 miles. It will start with a near detector and an intense beam of neutrinos produced at Fermi National Accelerator Laboratory in Illinois. It will end with a 10-kiloton far detector located underground in a laboratory at the Sanford Underground Research Facility in South Dakota. The distance between the two detectors will allow scientists to study how neutrinos change as they zip at close to the speed of light straight through the Earth.

“This will be the flagship experiment for particle physics hosted in the US,” says Jim Siegrist, associate director of high-energy physics for the US Department of Energy’s Office of Science. “It’s an exciting time for neutrino science and particle physics generally.”

The penguin anomaly

Not a great article but does help to explain what new physics might appear in the next run of the LHC.

A nice piece to read.



  • Originally it was thought the journey from one side of the Earth to the other - such as London to Antipodes Islands - would take 42 minutes
  • It examines the hypothetical scenario of falling through Earth
  • But student claims this doesn't take into account Earth's changing density
  • Alexander Klotz from McGill University has published a new estimate
  • He claims the journey would actually take 38 minutes and 11 seconds
FALLING THROUGH THE EARTH
Theoretically speaking, as a person falls through Earth, gravity is constantly changing as they make their way to the middle.
Consequently they would speed up as they approached the centre, and begin to slow down again as they made their way to the other side.
Ignoring drag effects due to the presence of air, it would take exactly the same amount of time to make the journey either side of the core.
Under these conditions, the speed reached during the descent would be enough for to reach the surface on the other side.
Earth’s density is less than 2,200lbs (1,000kg) per cubic metre at the surface, but 28,700 lbs (13,000kg) per cubic metre at the core - 3,960 miles (6,370km) below.
And 2,200 miles (3,500km) from the centre, about half way, there is also a dramatic jump in density near the outer core.
Using these numbers it would take 38 minutes 11 seconds to fall through Earth - four minutes and a second quicker than thought.

In at one atmosphere or so, the terminal velocity is only about 120mph so it would be a much longer ride. You'd need a hammock, tablet and some tunes. Probably some food too. :D

Why stranglets, micro-black holes or magnetic monopoles from the LHC will NOT eat the earth.

The world's largest, most powerful particle accelerator — the Large Hadron Collider (LHC) — is scheduled to turn back on in the next few days, according to a report in Nature on March 31.

Although this event is highly-anticipated around the world, there are two men who have remained silent: now-retired nuclear safety office, Walter Wagner, and Spanish journalist, Luis Sancho.

They have a history with the LHC.

Months before the particle collider was scheduled to turn on for the first time in 2008, Wagner and Sancho filed a lawsuit against the organizations behind the monster machine. The plaintiffs were:

  • U.S. Department of Energy
  • Fermi National Accelerator Laboratory
  • National Science Foundation
  • European Organization for Nuclear Research (CERN).
Needless to say, it takes a lot of guts, and perhaps a little insanity, to try and sue any one of those organizations, which are brimming with some of humanity's brightest intellectuals, let alone all of them. Especially right before they finished a $6 billion, 30-year project. In the two men's defense, Wagner and Sancho were trying to save the world from, what they thought, was almost-certain annihilation.

I just read about this which is too bad since it looks like it would have been fun. But you can still participate in the final round. It's a voting competition which pits various physics equipment like Fermi telescope agains Super Kamikande or the LHC. The final round of voting pits the LHC against the Dark Energy Camera. There are one paragraph descriptions of all of the contestants at the link, so it worth a look just for that.

Dark matter doesn't seem to be made of particles. In a study of colliding galaxies, it appears that dark matter doesn't react with itself in any way.

http://www.washingtonpost.com/news/...-matter-is-apparently-darker-than-we-thought/
In watching 72 galactic showdowns, Harvey and his colleagues found that dark matter didn't slow down when clusters collided. That was unexpected, because scientists think that dark matter is really common in the universe, perhaps making up as much as 90 percent of total matter. So dark matter (whatever it is) had to be hitting other dark matter en route, but these unseen particles weren't showing any evidence of dragging against each other.

So basically, dark matter is even less like "regular" matter than we thought.

LHC breaks old record of 4Tev with 6.5Tev run - http://www.symmetrymagazine.org/article/april-2015/lhc-breaks-energy-record?email_issue=729

I'm pretty sure that is for just one of the rings. If both rings can produce that much energy, then the LHC is on track to reach its design power of 13-14 Tev using both rings.

Also, IIRC, the luminosity of the beams is much higher than previously. Luminosity is a measure of how "bright" the beams are which I believe indicates the concentration of particles in the beam. Better luminosity means more collisions per run.
