DNA nanotubes offer promising applications in medicine

A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a breakthrough in the development of nanotubes—tiny "magic bullets" that could one day deliver drugs to specific diseased cells.

Turning proteins into glass

Duke Univ. researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology.

A golden bullet for cancer

A golden bullet for cancer

Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today. A team of scientists at Washington Univ. in St. Louis is currently working on a magic bullet for cancer. But their bullets are gold rather than silver.

Making cells feel right at home

The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of scientists from Houston's Texas Medical Center this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs.

Intentional environmental variations increase result validity in mouse testing

Intentional environmental variations increase result validity in mouse testing

For decades, the traditional practice in animal testing has been standardization, but a study involving Purdue Univ. has shown that adding as few as two controlled environmental variables to preclinical mice tests can greatly reduce costly false positives, the number of animals needed for testing and the cost of pharmaceutical trials.

Nano-technique gives detailed insight into failing heart cells

Nano-technique gives detailed insight into failing heart cells

Researchers have been able to see how heart failure affects the surface of an individual heart muscle cell in minute detail, using a new nanoscale scanning technique developed at Imperial College London. The findings may lead to better design of beta-blockers.

Merck KGaA acquires Millipore

Merck KGaA and Millipore Corporation announced that they have entered into a definitive agreement under which Merck KGaA will acquire all outstanding shares of common stock of Millipore, for US$ 107 per share in cash, or a total transaction value, including net debt, of approximately € 5.3 billion (US$ 7.2 billion).

Adapting to clogged airways makes common pathogen resist powerful antibiotics

Adapting to clogged airways makes common pathogen resist powerful antibiotics

People with cystic fibrosis frequently have lung infections that defy treatment. These chronic infections are often caused by common, environmental microbes that mutate in ways that let them live and thrive in viscous lung secretions. The same adaptations also make the pathogens less likely to be killed off by powerful antibiotics.

Nanoscopic material enables cartilage to do what it doesn’t do naturally

Nanoscopic material enables cartilage to do what it doesn’t do naturally

Northwestern Univ. researchers are the first to design a bioactive nanomaterial that promotes the growth of new cartilage in vivo and without the use of expensive growth factors. Minimally invasive, the therapy activates the bone marrow stem cells and produces natural cartilage. No conventional therapy can do this.

Killing cancer with nanobubbles

Using lasers and nanoparticles, scientists at Rice Univ. have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make "nanobubbles" by zapping gold nanoparticles inside cells.

Much ado about next to nothing

Much ado about next to nothing

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.

P2i showcases liquid repellent nano-coating for hearing aids
P2i showcases liquid repellent nano-coating for hearing aids

At the AudiologyNOW! 2010 show in San Diego next month, UK-based coatings company P2i will display their relatively new Aridion liquid-repellant nano-coating. Designed for exposure to humidity or sweat, the polymer layer is applied by a pulsed ion gas process that lower’s the hearing aid’s surface energy, coaxing water away from delicate components.

Submersible FlowCAM catches particle images and data in-situ and real-time

Fluid Imaging Technologies recently introduced its Submersible FlowCAM particle and cell imaging and analysis system at Ocean Sciences 2010 in Portland, Ore. The remote sensing platform can be used for continuous, unattended monitoring tethered to research vessels or autonomous submersibles.
