Chemists at Tufts University‘s School of Arts and Sciences have developed the world’s first single-molecule electric motor, which may create a new class of devices used in medicine and engineering.

It measures a mere 1 nanometer across (the current world record is a 200 nanometer motor).

According to E. Charles H. Sykes, Ph.D., associate professor of chemistry at Tufts, the team plans to submit… read more

World’s smallest 3-D printer

May 20, 2011

3D Printer

A very small and light 3-D printer prototype has been developed by researchers at the Vienna University of Technology.

The prototype is designed for use at home, using Internet blueprints to print custom 3-D objects. The desired object is printed in a small tub filled with synthetic resin.

The resin hardens under the illumination of intense beams of light. The synthetic resin is irradiated layer-by-layer at… read more

World’s poor to get own search engine

July 17, 2003

MIT researchers are developing a search engine designed for people with a slow net connection.

The user would e-mail a query to a central server in Boston. The program would search the net, choose the most suitable webpages, compress them and e-mail the results a day later.

World’s only ultrafast electron microscope takes 4-D ‘movies’ of molecules

December 26, 2007

California Institute of Technology researchers have developed an electron microscope that can create real-time 3D images of molecules as they form and break apart in femtosecond reactions, using a modified transmission electron microscope interfaced with an ultrafast laser.

World’s nuclear facilities vulnerable, warns UN agency

November 5, 2001

Nuclear plants are vulnerable to attacks by terrorists, according to a stark new warning by the International Atomic Energy Agency (IAEA).
The world’s 1300 nuclear facilities are not hardened to withstand “acts of war” like a deliberate hit by a large, fully-fuelled passenger jet, warns the IAEA’s director general, Mohamed ElBaradei.

In the US on October 29, following intelligence reports received by the FBI, the air space around all… read more

Imagine a clock precise to one second in a period comparable to the age of the universe (more than 13 billion years).

That’s what National Institute of Standards and Technology (NIST) scientists have built, with funding from DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program: two optical

World’s most powerful X-ray laser images biomolecules at ultra-high resolution

June 4, 2012

lysozyme-updated

An international team led by the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory has proved how the world’s most powerful X-ray laser can assist in cracking the structures of biomolecules.

The team’s experiments used SLAC’s Linac Coherent Light Source (LCLS) to obtain ultra-high-resolution views of crystallized biomolecules, including a small protein found in egg whites called lysozyme.

For decades, scientists have reconstructed… read more

World’s most powerful x-ray laser beam refined to scalpel precision

'Self-seeding' promises to speed discoveries, add new scientific capabilities
August 15, 2012

The LCLS’s new self-seeding improvements yield laser pulses focused to higher intensity in a much narrower band of X-ray wavelengths, as you can see in these spectrographs comparing a normal SASE (self-amplified spontaneous emission) pulse (left) and a seeded one (right). The results promise to speed research discoveries and may enable experiments that have never before been possible. Graph from J. Amman, et al. adapted by Greg Stewart, SLAC National Accelerator Laboratory

With a thin sliver of diamond, scientists at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory have transformed the Linac Coherent Light Source (LCLS) into an even more precise tool for exploring the nanoworld.

The improvements yield laser pulses focused to higher intensity in a much narrower band of X-ray wavelengths, and may enable experiments that have never before been possible.

In a process… read more

University of Leeds researchers have taken the lead in the race to build the world’s most powerful terahertz laser chip.

Terahertz waves, which lie in the part of the electromagnetic spectrum between infrared and microwaves, can penetrate materials that block visible light.

They have a wide range of possible uses, including chemical analysis, security scanning, remote sensing of chemical signatures of explosives in unopened envelopes, non-invasive… read more

World’s most powerful laser to tear apart the vacuum of space

November 4, 2011
The ELI-Attosecond Facility in Szeged, Hungary

A laser powerful enough to tear apart the fabric of space is planned as part of a new scientific project that aims to answer some of the most fundamental questions about our universe.

The Extreme Light Infrastructure (ELI) Ultra-High Field Facility would produce a laser so intense that scientists say it would allow them to reveal vacuum particles for the first time by pulling this vacuum “fabric”… read more

World’s Largest Working Computing Grid

September 7, 2004

This week, UK particle physicists will demonstrate the world’s largest working computing Grid. With more than 6,000 computers at 78 sites internationally, the Large Hadron Collider Computing Grid (LCG) is the first permanent, worldwide Grid for doing real science.

The Grid is designed to handle the expected 15 petabytes of data that will be produced each year by particle physics experiments at the Large Hadron Collider at CERN. By… read more

World’s Largest Truck Goes Robotic

November 10, 2008

The largest truck in the world is about to become the largest robotic vehicle in the world. Computer scientists from Carnegie Mellon University have teamed up with engineers from Caterpillar to automate the 700-ton trucks, which are made to haul loads up to 240 tons from mines.

World’s largest quantum computation uses 84 qubits

January 12, 2012

qubitsramsey

D-Wave Systems has carried out  a calculation involving 84 qubits on its D-Wave One quantum computing system, Technology Review Physics arXiv blog reports.

Their complex task was to calculate various  “two-color Ramsey numbers,” connected with the emergence of order in disordered systems.

World’s Largest Quantum Bell Test Spans Three Swiss Towns

June 17, 2008
(D. Salart, et al.)

In an attempt to test quantum nonlocality — the “spooky interaction at a distance” that occurs between two entangled particles, physicists from the University of Geneva have sent two entangled photons traveling to different towns located 18 km apart –the longest distance for this type of quantum measurement.

By separating the two interferometer measurements by 18 km (a photon would take 60 microseconds to cover the 18… read more
