A new study of living cells could revolutionize the way we test drugs

... ideas about how to improve the sensitivity of the detector in water and next time we will also use a more active micro-organism such as an amoeba. Yeast is a subdued organism and doesn’t generate much activity," says Professor Geim. "Probably, the most important outcome is that we defined an important goal. ...

Is there a pilot in the insect?

...vior, hidden in the insect's cockpit, are movement detector neurons that act as optic flow sensors. The team patiently decoded the functioning of these neurons using ultra-fine microelectrodes (with a diameter of a thousandth of a millimeter) and a specially designed microscope. They then produced an electron...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

...der of magnitude) due to usage of a split–scanning detector design capable of dwelling more on the organ of interest. This, together with radiation collection angles larger than in existing technology, constitutes a radical departure from the conventional Anger camera," he detailed. Besides providing improved...

Ancient ants arose 140-168 million years ago

...ector. The time lapsed prior to registering on the detector helps researchers determine the mass--or weight--of the particles. By targeting characteristic particles, or peptides, belonging to the viral coat protein, the virus can be positively identified by matching the results to entries in genetic databases...

Researchers use mass spectrometry to detect norovirus particles

Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

... The researchers suggest this low level locomotion detector is part of an evolutionary old system that helps animals detect quickly ?even on the periphery of their visual field ?whether a potential predator or prey is nearby. "Research on newly hatched chicks suggests that it works from very early on in an an...

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher

...body tissues. "The size compatibility between the detector and the detected species-DNA molecules in this case-makes this approach very attractive for further development of label-free electronic methods," said Star, who is an assistant professor of chemistry at Pitt. Star and his colleagues at Nanomix also...

Discovery that bacterium is phosphate gourmet key clue to what makes it most social of bacteria

...nal partial pathway also acts as a phosphate level detector - giving the bacterium even more tools to employ as a phosphate gourmet. Dr Whitworth also has evidence that the surprising extent of interaction between the three and a half phosphate signalling pathways is also found among the other 140 plus signa...

Making plant cells work like miniature factories

...arge ratios, and collected by an ion detector. The detector converts ion flux into a proportional electrical current. Finally, the magnitude of the electrical signals is recorded and plotted as a mass spectrum. The ability to sort and detect these ions at cellular-scale quantities is where the team hopes to ...

Researchers find gene that may be at root of potato blight

...in Wooster . "If you take a gun through the metal detector at an airport, the alarms go off," he said. "This gene (Avr3a) sends a signal alerting the plant that it is infected by the pathogen." Phytophthora infestans is the pathogen that causes late blight. For decades, controlling this disease has involved...

Signaling protein builds bigger, better bones in mice

... toward a detector. The number of ions hitting the detector at each mass-to-charge ratio (also known as m/z ratio) is recorded to produce a protein spectrum. A peak in the graph of the spectrum represents a protein (the identity of which is often unknown). The goal is to find a pattern of peaks that will dis...
