Fermilab is Building a 'Holometer' to Determine Once and For All Whether Reality Is Just an IllusionBy Clay Dillow
A Conceptual Drawing of the 'Holometer' via Symmetry
Researchers at Fermilab are building a “holometer” so they can disprove everything you thought you knew about the universe. More specifically, they are trying to either prove or disprove the somewhat mind-bending notion that the third dimension doesn’t exist at all, and that the 3-D universe we think we live in is nothing more than a hologram. To do so, they are building the most precise clock ever created.

Oficina para todo o Mundo
OSM fabrica martelos pneumáticos para vários países Empresa tem mais de mil clientes Mercado obriga a desenvolver novos produtos
A Oficinas de Santa Marta, oficina de metalomecânica de Pedras Salgadas, tem 20 trabalhadores, mil clientes e factura dois milhões de euros por ano.A empresa fabrica martelos pneumáticos de marca própria e, segundo o proprietário, “lidera” o mercado de perfuração de rocha ornamental.
A OSM começou há 20 anos quando José Ferreira fabricava pequenas peças paramartelos pneumáticos que se partiam ou se gastavam rapidamente.
O empresário investiu numamáquina de controlo numérico e criou a OSM.
Um ano depois criava uma rede comercial em Portugal e Espanha.Hoje tem mais de mil clientes. O Brasil é o principal, mas também exporta para França, Suíça, Alemanha, Itália, África do Sul, Angola e Turquia.
Agora está a desenvolver novos produtos porque “as exigências de mercado são cada vez maiores”.

Student-made device helped wounded in Haiti
(Reuters Health) - When surgeons from Harvard Medical School went to Haiti soon after last January's earthquake, they took along some experimental three-dollar devices they hoped would help victims' wounds heal faster. The devices had never been tested in patients before, but they didn't need electricity, and they could be operated by the average person -- exactly what was needed in the post-earthquake devastation.
Designed by engineering students at the Massachusetts Institute of Technology, each device involved an accordion-like plastic pump (in reality an industrial-size toilet plunger) and some tubing. The tubing goes under an air-tight seal over the wound, and the pump is squeezed to create suction. The resulting vacuum provides what's known as "negative wound pressure therapy."

Real-Life Iron Man Exoskeleton Gets a Slimmer, More Powerful SequelBy Dan Nosowitz
Micro-Instrumentos Musicais:The XOS Exoskeleton, which was first shown off about two and a half years ago, was the first full-body suit that really evoked the sci-fi and comic fan's dream of donning a suit that grants superhuman strength. Late last week, Raytheon-Sarcos demonstrated the newest XOS suit--the sequel, you might say.Not so coincidentally, Paramount Pictures was on hand to talk about the suit's connections to Iron Man 2, which comes out on DVD/Blu-ray this week. But unlike Iron Man 2, which was all about more (more villains! More length! More plotlines!), the XOS-2 is all about less: Less energy required, less heavy, and less muscle required to lift objects.Most importantly, the ratio between actual and perceived weight lifted is much improved, going from 6:1 in the XOS-1 to a whopping 17:1 in the XOS-2. A 50-pound weight feels like only three pounds, and a 200-pound weight feels like only 12. Test engineer Rex Jameson (that name even sounds like a superhero, doesn't it?) was able to punch through four one-inch boards strapped together, and repeatedly lifted a 200-pound artillery shell.
Listen: Microscopic Instrument Produces Tones Humans Can HearBy Julie Beck
Had you happened to be in the eastern Netherlands on Sunday, you could have had the opportunity to hear a new composition: “Impromptu No. 1 for Micronium.” However, you probably wouldn’t have seen much. That’s because the micronium, while it may sound like a miniature tuba, is actually the first musical instrument measured in micrometers whose tones are audible to humans.Created by students at the University of Twente, the micronium is made up of springs one tenth the thickness of a human hair hung with a mass weighing no more than a few dozen micrograms. The springs are plucked by miniature combs that fit together just so, producing a tiny movement and a tone. Six of these tones can fit on one microchip, and by combining chips you get the range of tones needed to play more varied compositions.

Nano-Gyroscopes Will Let Cell Phones Navigate Indoors, Underground
By Julie Beck Posted 10.07.2010 at 12:16 pm
Israeli researchers have created the tiniest-ever optical gyroscopes, as small as a grain of sand, but still maintaining the keen accuracy of their counterparts hundreds of times larger. Optical gyroscopes are generally used for navigation in airplanes, ships and satellites, in which they track movement without reference to external navigation points, by measuring the vehicle’s rotation rate and linear acceleration. This is called inertial navigation. It’s extremely accurate but, up until now, only possible in gyroscopes and weighing two to three pounds.
NASA Moves Ahead With Robotic Plane to Take Mars Exploration to the SkiesBy Clay Dillow Posted 10.07.2010 at 4:15 pm
As a general rule, when NASA flies a scientific mission all the way to Mars, we expect that mission to last for a while. For instance, the Spirit and Opportunity rovers were slated to run for three months and are still operating 6 years later. But one NASA engineer wants to send a mission all the way to the Red Planet that would last just two hours once deployed: a rocket-powered, robotic airplane that screams over the Martian landscape at more than 450 miles per hour.
ARES (Aerial Regional-Scale Environmental Surveyor) has been on the back burner for a while now, and while it's not the first Mars plane dreamed up by NASA it is the first one that very well might see some flight time over the Martian frontier. Flying at about a mile above the surface, it would sample the environment over a large swath of area and collect measurements over rough, mountainous parts of the Martian landscape that are inaccessible by ground-based rovers and also hard to observe from orbiters.

Tunable, Stretchable Optical Materials
Active metamaterials might be used in solar cells that change properties with the weather.
By Katherine Bourzac
The field of metamaterials has yielded devices that seem to come from science fiction--invisibility cloaks, highly absorbent coatings for solar cells and ultra-high-resolution microscope lenses. Metamaterials are precisely tailored to manipulate electromagnetic waves--including visible light, microwaves, and other parts of the spectrum--in ways that no natural materials can.
With few exceptions, however, these materials work in a very limited range of wavelengths of light, making them impractical--an invisibility cloak isn't very useful if it only redirects light of one color but can be readily seen under others. Now researchers at Caltech have shown that by mechanically stretching an optical filter made from a metamaterial, they can dynamically change which wavelength of infrared light it responds to.

Russia Aims to Launch First-Ever Commercial Space Station Within Five YearsBy Julie BeckA pair of Russian aerospace companies have announced plans to launch the first commercial space station, in 2015 or perhaps 2016. The station will have room for up to seven astronauts, scientists, and wealthy citizens to perform experiments or just take in the scenery. Meanwhile, U.S. company Bigelow Aerospace is also aiming to launch a private space station, possibly as soon as 2015 -- the race is on.

Spinning Slice of Graphene Is Fastest Spinning Object Ever, At 60 Million RPMBy Dan Nosowitz
Graphene, Captured by a Transmission Electron Microscope National Center for Electron Microscopy
Scientists at the University of Maryland at College Park have managed to clock a floating piece of graphene at an unbelievable 60 million rpm, far faster than any other macroscopic object yet measured. Even crazier: Given graphene's strength, one of the scientists says that may only be a thousandth of its possible top speed.
Graphene is a derivation of graphite, which in turn comes from carbon. Basically, graphite comes from stacked sheets of carbon, and graphene is made of one-atom-thick separated graphite sheets, which form a honeycomb crystal structure. Graphene has some pretty incredible properties: It conducts electricity better than any other known material at room temperature and exhibits a startling amount of strength, given its 2D structure. A bit of graphene the same thickness as plastic wrap would require 2.5 tons of force to puncture it.
