In order to develop an extremely sensitive temperature sensor, scientists took a close look at temperature-sensitive plants. However, they did not mimic the properties of the plants; instead, they developed a hybrid material that contains, in addition to synthetic components, the plant cells themselves.

Graphene lightbulb to go on sale later this year
A graphene lightbulb with lower energy emissions, longer lifetime and lower manufacturing costs has been launched thanks to a University of Manchester research and innovation partnership.
A quantum sensor for nanoscale electron transport
In an experiment, scientists used nitrogen-vacancy centers in diamond to sense the properties of magnetic field noise tens of nanometers away from the silver samples.
Microsecond Raman imaging might probe cells, organs for disease
A vibrational spectroscopic imaging technology that can take images of living cells could represent an advanced medical diagnostic tool for the early detection of cancer and other diseases.
Biomedical researchers convert microbubbles to nanoparticles
Biomedical researchers have successfully converted microbubble technology already used in diagnostic imaging into nanoparticles that stay trapped in tumours to potentially deliver targeted, therapeutic payloads.
High-tech method allows rapid imaging of functions in living brain
Researchers studying cancer and other invasive diseases rely on high-resolution imaging to see tumors and other activity deep within the body's tissues. Using a new high-speed, high-resolution imaging method, researchers were able to see blood flow, blood oxygenation, oxygen metabolism and other functions inside a living mouse brain at faster rates than ever before.
Physicists report technology with potential for sub-micron optical switches
A team of scientists believes that its technology could result in optical switches with sub-square-micron footprints, potentially allowing densely packed switching fabrics on a chip.
Prototype nanoneedles generate new blood vessels in mice
Scientists have developed tiny nanoneedles that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice.
Researchers develop molecular DNA backbone of super-slim, bendable digital displays
A new study suggests that a novel DNA-peptide structure can be used to produce thin, transparent, and flexible screens.
Next important step toward quantum computer with quantum dots
Scientists have have succeeded in linking two different quantum systems.
Graphene field-effect transistor is key to faster DNA sequencing
Graphene looks to hold the key to real-time, high throughput DNA sequencing, a technique that would revolutionise medical research and testing.
3D imaging of objects with details as small as 25 nanometers
Scientists have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical elements were distributed in their sample and whether these elements were in a chemical compound or in their pure state.
Split x-ray flash shows rapid processes
New method should make more precise experiments on x-ray lasers possible.
Fascinating quantum transport on a surface
Topological insulators are an exceptional group of materials. Their interior acts as an insulator, but the surface conducts electricity extremely well. Scientists now could measure this for the first time directly, with extremely high temporal resolution and at room temperature. In addition, they succeeded to influence the direction of the surface currents with a polarized laser beam.
Wrapping carbon nanotubes in polymers enhances their performance
Scientists developed a technique that 'exfoliates' aggregated clumps of CNTs and disperses them in solvents. It involves wrapping the tubes in a polymer using a bond that does not involve the sharing of electrons. The technique is called non-covalent polymer wrapping.
