A group of South Korean researchers has developed a new method to cause cell death in both living fish and lab bowel cancer cells using a magnetic field. This application of electro-magnetism triggers a death signal that leads to programmed cell death. The researchers published their findings in the journal Nature Materials. Treating cancer effectively [...]

Most lasers are made up of silicon wafers using expensive processes, similar to the ones used to make microprocessors. Scientists have designed a new way to print a type of organic laser onto any surface, using technology similar to the one found in many homes. The scientists published their findings in the journal Soft Matter. [...]

Unlike the popular belief that sleeping more on the weekends can help sleep deprived people catch up on sleep, a new sleep study has shown that sleeping in on the weekends will make you sleepier come Monday morning. The scientists announced their findings through UT Southwestern.  A great myth of sleep deprivation is that if [...]

the chaotic origins of dynamic assembly in cells

A newly published study details how Harvard scientists used Total Internal Reflection Fluorescence microscopy (TIRF) to capture the first ever real-time footage of the initial five seconds in the life of membrane vesicles. Scientists have captured real-time footage of how a crucial cellular process begins, findings that overturn a long-held theory about how the chaotic [...]

study shows drug can purge dormant HIV

A newly published study from the University of North Carolina found that the drug vorinostat, a deacetylase inhibitor that is used to treat some types of lymphoma, was able to dislodge the dormant HIV virus in patients. Chapel Hill, North Carolina — Researchers from the University of North Carolina at Chapel Hill have published pioneering [...]

fluoxetine – commonly known as Prozac – shows promise as an antiviral agent

Published in early July in the journal of Antimicrobial Agents and Chemotherapy, a new study from UCLA scientists found that fluoxetine, commonly known as Prozac, showed promise as an antiviral agent, did not interfere with either viral entry or translation of the viral genome and markedly reduced the production of viral RNA and protein. UCLA [...]

Platinum compound may offer an alternative to cisplatin

A newly published report describes the new drug candidate known as phenanthriplatin, a compound that showed a different pattern of activity than that of cisplatin and, depending on the cancer type, was found to be four to 40 times more potent than cisplatin. Drugs containing platinum are among the most powerful and widely used cancer [...]

Japanese scientists have been able to induce stem cells to create liver-like tissue in a dish. The new findings were reported online by the journal Nature, but the scientists have yet to publish their findings. Once the achievement is accomplished, there could be several big clinical implications. This could mean that it would be possible [...]

physicists use ultrafast lasers to create first tabletop X-ray device

Physicists have generated the first laser-like beams of X-rays from a tabletop device, opening the door for devices that may be used by scientists to gain a better understanding of the nanoworld. An international research team led by the University of Colorado Boulder has generated the first laser-like beams of X-rays from a tabletop device, [...]

researchers have deduced the shape of 18 families of transmembrane proteins

Scientists at Harvard Medical School developed algorithms that allowed them to use evolution as their guide to deduce the three-dimensional structure of 18 families of transmembrane proteins. The molecules that drugmakers would most like to target are also among the hardest to study: Transmembrane proteins. These proteins connect our cells to their environment to sense, [...]

controlling glucose levels may not reduce kidney failure in type-2 diabetes

By searching available medical literature and evaluating seven randomized trials that involved 28,065 adult patients who were monitored for two to 15 years, researchers from Yale University found that compared with those who had usual treatment, intensively controlling glucose with higher doses of medication did not definitively reduce the risk of impaired kidney function, the [...]

Crowding Causes Internal Cell Structure Alignment

May 24, 2012

0 Comments

By mimicking the crowded environment in actual cells, a team of researchers found that certain molecules organize as they would in the body, inducing a dramatic alignment of the protein networks outside the cell and causing the cell to align its internal structure. When researchers conduct experiments on the way cells grow and respond to [...]
