PARS tech turns bodies transparent

By - August 1, 2014 4 Pictures
Ordinarily, when scientists want to see specific cells within a piece of biological tissue, they first have to remove that tissue from the body, slice it very thin, then examine those two-dimensional slices using a microscope. Imagine, though, if the tissue could be made transparent – seeing tagged cells within it would be sort of like looking at three-dimensional bubbles inside an ice cube. Well, that's just what a team at Caltech have done using a technique known as PARS, or perfusion-assisted agent release in situ. Read More

Achilles' heel to lower defenses of antibiotic-resistant bacteria found

By - June 20, 2014 1 Picture
The discovery of antibiotics is one of the most important breakthroughs of the 20th century. But their effectiveness and low cost has led to their overuse, resulting in the worrying rise of antibiotic-resistant bacteria, or so-called superbugs. Researchers at the University of East Anglia (UAE) in England have now uncovered an Achille's heel in the bacterial cell defenses that could mean that bacteria wouldn't develop drug-resistance in the first place.

New sensor to detect food-borne bacteria on site

By - June 15, 2014 1 Picture
It is estimated that every year in America there are around 76 million food-borne illnesses that result in 325,000 hospitalizations and over 5,000 deaths. One of the main causes is the disease "Listeria", which has the highest hospitalization (92 per cent) and death (18 per cent) rate among all food-borne pathogen infections. Now researchers at the University of Southampton say that they are trialling a device designed to detect these bacteria directly on food preparation services, and without the need to send samples away for laboratory testing.

Meet the newest element deemed critical for animal life: bromine

By - June 6, 2014 1 Picture
Joining the ranks of carbon, selenium, sulfur and 24 others as an essential element for animal life is element 35 – bromine – long considered inessential to life and moreso, shunned as a toxic disease-causing agent. However, researchers have identified the role bromine holds in animal development, even demonstrating death in fruit flies without access to this element named for its identifying stench. Read More

Researchers uncover link between neurodegenerative diseases and molecular scaffold

By - June 4, 2014 1 Picture
Researchers from King's College London (KCL) claim to have uncovered a link between a molecular scaffold, that allows for interaction between key components of a cell, and the debilitating effects of neurodegenerative diseases. It is possible in the long term that this line of research will yield a new target for tailored treatment in the fight against devastating afflictions such as dementia and motor neuron disease.

Drug-delivering nanoparticles pose a triple threat to cancer

By - April 16, 2014 2 Pictures
Delivering drugs that can knock out tumor cells within the body, without causing adverse side effects, is a tricky busines. It's why scientists have taken to engineering new and creative types of nanoparticles that do the job. Increasing a nanoparticle's ability to carry more drugs expands treatment options, but creating nanoparticles capable of delivering more than one or two drugs has proven difficult – until now. Scientists at MIT report creating a revolutionary building block technique that's enabled them to load a nanoparticle with three drugs. The approach, they say, could be expanded to allow a nanoparticle to carry hundreds more. Read More

Stamp of approval for new living cell printing technique

By - February 27, 2014 1 Picture
Researchers in Houston have developed a cost effective method for printing living cells, claiming almost a 100 percent survival rate. The method, which is akin to a modern version of ancient Chinese wood block printing, allow cells to be printed on any surface and in virtually any two dimensional shape. And while current inkjet printers adapted to print living cells can cost upwards of US$10,000 with a cell survival rate of around 50 percent, this simple new technique could see the cell stamps produced for around $1.

Charged polymers unlock door to deliver nanoparticles to cancer cells

By - February 11, 2014 1 Picture
In recent years, we've seen various research efforts looking to specifically target cancer cells as a replacement for the shotgun approach employed by chemotherapy that also damages healthy cells. The trick is to develop a delivery vehicle that identifies and targets only cancer cells, while ignoring the healthy ones. Researchers have found charged polymers have this ability, opening the door for nanoparticles containing cancer-fighting drugs to deliver their payload directly to the cancer cells. Read More
