Nano-needles for cells

ottilia.saxl@btinternet.com (Anne Sliper Midling) — Fri, 24 May 2013 10:48:35 GMT

Nano-sized needles developed by researchers can force medicine into cells, even when the cell membranes offer resistance. The needles will make it easier to study the effects of medicines on cells.

Gold nanocrystal vibration captured on billion-frames-per-second film

A billon-frames-per-second film has captured the vibrations of gold nanocrystals in stunning detail for the first time.

Scientists develop cheaper, more efficient fuel cells

ottilia.saxl@btinternet.com (Canadian Light Source) — Thu, 23 May 2013 20:06:23 GMT

Using the Canadian Light Source (CLS) synchrotron, researchers have discovered a way to create cheaper fuel cells by dividing normally expensive platinum metal into nanoparticles (or even single atoms) for use in everything from automobiles to computers.

Research offers promising new approach to treatment of lung cancer

ottilia.saxl@btinternet.com (Oregon State University) — Thu, 23 May 2013 13:06:23 GMT

Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumours.

Scientists uncover how grapefruits provide a secret weapon in drug delivery

ottilia.saxl@btinternet.com (Julie Heflin) — Wed, 22 May 2013 09:40:11 GMT

Grapefruits have long been known for their health benefits, and the subtropical fruit may revolutionize how medical therapies like anti-cancer drugs are delivered to specific tumour cells. Scientists have discovered how to use grapefruit to develop medicine.

Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.

...Iron-platinum alloys could be new-generation hard drives

ottilia.saxl@btinternet.com (Andy Fell) — Mon, 20 May 2013 21:25:49 GMT

Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron and platinum with an ordered crystal structure. Researchers have now found a convenient way to make these alloys and tailor their properties.

Advanced carbon nanocomposite materials for planes, trains and automobiles

ottilia.saxl@btinternet.com (Jennifer Chu) — Mon, 20 May 2013 13:08:23 GMT

These days, aerospace engineering is all about the light stuff: building airplanes with lighter wings, fuselage and landing gear in an effort to reduce fuel costs. Advanced carbon-fibre composites have been used in recent years to lighten planes’ loads. These materials can match aluminum and titanium in strength but at a fraction of the weight, and can be found in aircraft like the Boeing 787 and Airbus A380, reducing such jets’ weight by 20 per cent.

Physicists create the smallest drops of liquid ever made in the lab

ottilia.saxl@btinternet.com (David Salisbury) — Fri, 17 May 2013 10:27:24 GMT

Physicists may have created the smallest drops of liquid ever made in the lab. That possibility has been raised by the results of a recent experiment conducted by physicist Julia Velkovska and her colleagues at the Large Hadron Collider, the world’s largest and most powerful particle collider located at the European Laboratory for Nuclear and Particle Physics (CERN) in Switzerland.
