New Microchip for Protein Sorting
While other scientists have used similar continuous flow techniques to separate large molecules like long DNA, the MIT team succeeded with the tinier
proteins. "This is the first time physiologically relevant molecules like proteins have been separated in such a manner," said Han. "We can separate t...
World's largest flower evolved from family of much tinier blooms
The plant with the world's largest flower -- typically a full meter across, with a bud the size of a basketball -- evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science. Their genetic analysis of rafflesia reveals that it is closely rel...
New 'near-field' radiation therapy promises relief for overheating laptops
...t come without a cost.
Take the laptop, for example. Its components, especially its billions of semiconductor electronic circuits, are growing ever tinier
while the instrument's power and capacity increase. But heat generated by electric current can cause the circuits to melt and the laptop hardware to f...
New kind of MRI enables study of magnets for computer memory
...e ferromagnetic resonance force microscopy," or scanned probe FMRFM, and it involves detecting a magnetic signal using a tiny silicon bar with an even tinier
magnetic probe on its tip.
As the probe passes over a material, it captures a bowl-shaped image: a curved cross-section of an object. The magnetic ...
Using catalysts to stamp nanopatterns without ink
...ormer Toone graduate student now working as a postdoctoral researcher in Whitesides group.
A 100 nanometer limit of resolution is about 1,000 times tinier
than a human hairs width. While that seems very precise, the Duke team now reports it can boost accuracy limits to less than 2 nanometers by entirely ...
Transistors made from single electrons
...ering professor Robert Blick and physicist Dominik Scheible of Ludwig-Maximilians University in Munich, could eventually lead to advances such as much tinier
semiconductor chips; more powerful, yet less power-hungry, cell phones; and long-lived remote sensors for monitoring everything from airborne toxins t...
A new tool for keeping computers cool
...becomes heat rather than light. Computer chips can produce the same 100 watts of thermal energy as the bulb, but that energy is concentrated in a much tinier
"When you have a large amount of thermal energy in a very small spot, the temperature becomes very, very high, to the point where materials ...
