Inexpensive 3D-printed lens gives terahertz imaging a boost

Terahertz radiation is a growing field of technology that enables faster materials analysis than X-ray examination, and provides non-destructive, internal analysis of a raft of different types of materials. Now researchers have developed a way of manufacturing lenses operating at this frequency that are simple and inexpensive, but are claimed to produce near-flawless images which could vastly improve biomedical imaging as well as biological and explosive security scanning.Read More

Weasel takes down Large Hadron Collider

A small furry animal today took on the largest atom smasher ever made, and won. According to internal documents at CERN, the Large Hadron Collider was knocked out of commission at about 5:30 am CEDT when a weasel caused a "severe electrical perturbation" when it stepped on the bare connections of a 66,000 volt transformer. This not only proved instantly fatal to the weasel, but it also short circuited the power system, causing the LHC to execute a fast abort as the sudden power loss created a series of anomalies.Read More

Prematurely born lambs kept alive in artificial external placenta – human babies could be next

When babies are born extremely premature – before 24 weeks of development in the womb – their lungs aren't strong enough to provide their organs with oxygen they need to develop properly. Nor are they strong enough to handle artificial ventilation. The result can mean a brief life for these tiniest of babies. A new artificial placenta that mimics conditions in the womb being developed by researchers at the University of Michigan might provide new hope.Read More

Screening existing drugs to uncover new weapons against antibiotic-resistant bacteria

Bacteria that are resistant to standard antibiotics represent one of the biggest threats to global health today, and one particular type, known as carbapenem-resistant Enterobacteriaceae (CRE), was recently classified by the US Centers for Disease Control and Prevention as having the most urgent antimicrobial resistance threat level possible. Help might just be at hand though, with researchers from the Beth Israel Deaconess Medical Center (BIDMC) using a screening method to identify existing drugs that might well prove effective against the dangerous bacteria.Read More

Discovery points to a reason for neuron death in stroke victims

It's well known that conditions such as schizophrenia, as well as strokes, seizures and traumatic brain injuries cause increased acidity around neurons in the brain, but scientists have struggled to understand exactly why this occurs. Now, researchers from the University at Buffalo may have pinpointed the reason, finding that an elusive receptor might play a big role.Read More

High performance transistors created on flexible plastic sheets

Using a technique known as nanoimprint lithography, researchers at the University of Wisconsin-Madison and partners have created a breakthrough method to allow the simple manufacture of inexpensive, high-performance, wireless-capable, flexible Metal Oxide Semiconductor Field Effect Transistors that overcome many of the operation problems encountered in devices manufactured using standard techniques. Created on large rolls of pliable plastic, these MOSFETs could be used to make a host of devices ranging from wearable electronics to bendable sensors.

Portable device detects Ebola on the spot

It would definitely be an understatement to say that the sooner the Ebola virus is detected in blood samples, the better. Unfortunately, those samples currently have to be shipped off to labs for analysis, often far from the area being studied. That could soon change, though, as a compact new device can identify Ebola in under half an hour.Read More
