Stunning Image of a Single Molecule

Even the bonds to the hydrogen atoms at the pentacene’s periphery can be seen

The detailed chemical structure of a single molecule has been imaged for the first time, say researchers.  The physical shape of single carbon nanotubes has been outlined before, using similar techniques – but the new method even shows up chemical bonds.

Scientists have developed a technique for retrieving fingerprints from fired bullets

A scientist has fabricated a new technique to ‘see’ fingerprints erased from fired bullets.  Alex Goddard of University of Leicester has developed a technique that involves studying the chemical and physical interactions occurring between the metal and the fingerprint sweat deposit — which have been overlooked until now.

New Laser Probe Developed For Space Program Could Spot Cataracts Earlier

New Laser Probe Developed For Space Program Could Spot Cataracts Earlier 

 A beam of light from a slit-lamp microscope focused on a cataract.

Cataracts are the single biggest cause of blindness and are responsible for almost half of all cases worldwide. A new laser probe, originally developed for the U.S. space program, has been shown to detect the condition earlier than is otherwise possible. Its developers say that the technique can tell that a cataract is forming even when an eye looks perfectly clear.

Ten Minute Blood Test To Identify Cancer Proteins

Ten Minute Blood Test To Identify Cancer Proteins 

 A microfluidic chip identifies 35 proteins in a drop of blood within 10 minutes.

Measuring proteins in the blood can help doctors determine patients’ cancer risk and monitor the health of the elderly and people with chronic diseases. But current methods for testing these proteins are too expensive and require too much blood to be performed regularly. A microfluidic chip in clinical trials does on a single chip in 10 minutes what normally takes multiple technicians hours to do–and with just a single drop of blood. Researchers hope to make bedside diagnostics based on blood proteins a reality by bringing down the cost of such tests by at least an order of magnitude.

World’s Most Powerful Electron Microscope

World’s Most Powerful Electron Microscope 

 Titan 80-300 Cubed Microscope

The Hubble telescope has a competitor. It’s not a telescope, but a microscope. The competition isn’t looking for stars and galaxies, but seeking atomic levels instead. McMaster University Canada has installed the world’s most powerful electron microscope at its Center for Electron Microscopy. Built in the Netherlands, the Titan 80-300 Cubed microscope is the planet’s most powerful and advanced microscope.

Mini Microscope Watches Mouse Brain Cell Activity

A microscope small enough to be mounted to the head of a freely moving mouse makes it possible to watch brain cell activity and whole animal behavior simultaneously in mice. The device offers researchers a new way to study of human diseases using transgenic mice. (Videos after the jump)

Researchers Develop Portable Medical Scanner With Inexpensive Digicam Sensor

Researchers Develop Portable Medical Scanner With Inexpensive Digicam Sensor 

A lot can be learned from simply counting the cells found in a sample of blood or water; the rub is that it requires either a lengthy and complex manual process with an expensive microscope or a a quicker process with an even more expensive flow cytometer. Now, UCLA researchers have devised a compact system that scans samples with a cheap CCD digicam sensor to quickly spot and count 100,000 different kinds of cells in a sample. Please note my resistance here to the general tendency to call any type of advanced portable medical scanner a real-life tricorder, but that’s kind of what it’s like.

Optical Sensor Spots Oral Cancer

Optical Sensor Spots Oral Cancer 

 

For the first time, an optical sensor, developed by researchers at the University of California, Los Angeles (UCLA), can measure proteins in saliva that are linked to oral cancer. The device is highly sensitive, allowing doctors and dentists to detect the disease early, when patient survival rates are high.
