DNA Molecules Used To Assemble Nanoparticles

...sed cell, either killing it from within or sending out a signal to identify it. But making the particles is notoriously difficult and time-consuming. The nanoparticle system used by Baker's lab is based on dendrimers, star-like synthetic polymers that can carry a vast array of molecules on the ends of t...

...ed back into the body. The stuff that isn't pumped out is just like urine: it goes in the toilet," Dr. Szerlip says. Preliminary findings on 10 patients at the University of Michigan Medical Center and Cleveland Clinic Foundation showed the device was safe and produced desired results such as reducing c...

...tep in the process? The hunch paid off and turned out to be the final piece of the puzzle. The discovery, says Zhang, demonstrates that human stem cells do not necessarily differentiate in linear fashion, as scientists always believed. Rather, a series of complex overlapping changes may well be the dev...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

...do their dirty work," said Spiegelman, who carries out basic research on fat cells and metabolic pathways in diabetes and cancer at Dana-Farber. "It offers the opportunity to try to understand what makes these fatty acids so deleterious, and what we need to avoid." Moreover, it is possible that in the f...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...t the need for drilling, making it easier to tease out what is living at depth in oceanic crust. The fluids that emerge may come in bursts when earthquakes occur; fluid flow may therefore repeat episodically over hundreds of thousands of years as abyssal hills are uplifted and spread away from the mid-oc...

UAB scientists discover the origin of a mysterious physical force

...are strongly orientated in such a way as to cancel out the electric field, and on some occasions, to reverse it. This abnormal behaviour was discovered by the same researchers and published in Physical Review Letters in April 2004. The scientists have now discovered that this strange property is respons...

It's not all genetic: Common epigenetic problem doubles cancer risk in mice

...ple, the current experiments were designed to find out whether the loss of imprinting is involved in cancer's development or just in its progression. "Most researchers, including me, expect epigenetic differences to influence progression -- whether a tumor would grow slowly or quickly, or whether it wou...
