Researchers at the University of Wisconsin-Madison have discovered that a protein called Munc13-4 helps cancer cells secrete large numbers of exosomes -- tiny, membrane-bound packages containing proteins and RNAs that stimulate tumor progression. The study, which will be...
For a thousand years, people have reported feeling better by meditating but there has never been a systematic study that quantified stress and how much stress changes as a direct result of meditation until now. U.S. Army Research Laboratory...
A new synthetic enzyme, crafted from DNA rather than protein, flips lipid molecules within the cell membrane, triggering a signal pathway that could be harnessed to induce cell death in cancer cells. Researchers at University of Illinois at Urbana-Champaign...
For the first time ever, researchers at the Texas Tech University Health Sciences Center (TTUHSC) have identified a specific amino acid residue that is responsible for inverting the communication between the opening of the activation gate and the...
The quest to understand what causes Alzheimer's disease -- and to treat it -- is complicated by the disease's long, slow progression and the difficulty of collecting brain tissue samples. But in a large-scale analysis published June 21...
Alzheimer's disease could be better treated, thanks to a breakthrough discovery of the properties of the metals in the brain involved in the progression of the neurodegenerative condition, by an international research collaboration including the University of Warwick. Dr...
In a pilot study by a team of researchers at The University of Texas at Austin, crystalline particles of titanium dioxide -- the most common white pigment in everyday products ranging from paint to candies -- were found...
A groundbreaking discovery by University of Alberta researchers has identified previously unknown therapeutic targets that could be key to preventing the spread of cancer. In a new study published in Nature Communications, the team found that by inhibiting several...
A new microscope system can image living tissue in real time and in molecular detail, without any chemicals or dyes, report researchers at the University of Illinois. The system uses precisely tailored pulses of light to simultaneously image with...
A scientist at Duke University says the natural evolution of social organizations into larger and more complex communities that exhibit distinct hierarchies can be predicted from the same law of physics that gives rise to tree branches and...
