Nanoparticles carry cancer-killing drugs into tumor cells

...tumors in human ovaries. This surprisingly evident connection has now been proven by a team at the Medical University of Vienna, who published their data in the science journal Molecular Cancer Research. The team, who is supported by funding from the Austrian Science Fund FWF, also discovered the possible genet...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...hey then reported feeling less pain. The mind-body connection is quite clear." The findings are based on sophisticated brain scans from 14 young healthy men who agreed to allow researchers to inject their jaw muscles with a concentrated salt water solution to cause pain. The injection was made while they were ...

Unraveling a stomach cancer puzzle

...appens in humans. So this is also the first time a connection between stomach cancer and this signaling pathway has been made." Team leader Dr. Matthias Ernst, also from LICR, says that these basic research findings may one day impact directly on the treatment of stomach and other cancers. "We've demonstrated ...

How monarch butterflies are wired for navigation

...esearchers were surprised to discover a key wiring connection between the light-detecting navigation sensors in the butterfly's eye and the creature's circadian clock--a critical link if the butterflies are to compensate for the time of day in using their "sun compass." The researchers' techniques include mole...

Scientists discover the body's marijuana-like compounds are crucial for stress-induced pain relief

...stress-induced analgesia dramatically, proving the connection between pain suppression and the release of these marijuana-like compounds. The enzyme that inhibits the formation of the naturally occurring marijuana-like compound 2-AG is called monoacylglycerol lipase, and it is this enzyme that could be a targe...

Where Bacteria Get Their Genes

...to another. Bacteria can also make contact by tiny connection tubes through which they exchange pieces of DNA. They can also take up genetic material from the environment. Ochman thinks the team's findings will stir new research in bacterial evolution. "It should be exciting to see whether gene transfer has be...

Mapping neuron connections in the brain

...or many types of neurons. With this method, neuron connection maps could be used to create computer simulations of neural circuits involving tens of thousands of neurons with biologically realistic connections--and provide a practical way to begin untangling the mysteries of the brain. ### Citation: Amirikian...

Scientists discover global pattern of big fish diversity in open oceans

... just really neat. It tells us something about the connection of diversity and ocean structure and it shows that human activity is changing those patterns for the largest fish." Hotspots for Conservation? These open ocean hotspots appear vitally important for many different species, from zooplankton to tuna, ...

Brain Scan Study of Smokers Reveals Signature of Craving

...m is now examining methods that may help break the connection between cigarette cues and brain activity as a mea...prior to smoking cessation may help extinguish the connection between smoking and the rewarding affects of nicotine, thereby easing the brain's sensitivity to dru...

Life detection instrument passes key test on road to Mars

...unning liquid water on the surface of Mars." "The connection between water and life has been made very strongly, and we think there is a good chance there is or was some life form on Mars," Mathies said. "Thanks to Alison's work, we're now in the right position at the right time to do the right experiment to f...

Whole genome promoter mapping - Human Genome Project v2.0?

...tic switches work in a cell, and investigate their connection to human diseases," said Dr. Ren, who is also a member of the Rebecca and John Moores UCSD Cancer Center. He and his colleagues have made the data freely available on online public databases. Dr. Robert Strausberg, Vice-President of Human Genomic Me...

Researchers Identify Cause of Early Bird Sleep Disorder

...eep at different times. And there is apparently no connection to the better-known problem called narcolepsy. Ptacek said it was also found -- in the family's six affected individuals -- that "they all have asthma, and they all have migraine headaches, with aura. Now, that could be purely coincidental, but a mo...

Some Brain Cells Change Channels

... its neighbor are so close to one another at these connection points, called synapses, that molecules released from one cell travel immediately to the next. These molecules dock at specific places, or receptors, on the cell and trigger "channels" in the cell's membrane to open. Depending on the receptor and th...
