UC Davis scientists discovered how salmonella becomes lethal for AIDS patients by finding the defect in immune response that allows it to cross the gut barrier and infect other organs. The study suggests Th17 cells play a crucial role in the inflammatory response, recruiting immune system cells to the site of infection.
Graphene outperforms silicon in terms of mobility, allowing for high-speed electronic devices and biochemical sensors. Researchers found that thermal vibrations have a small effect on electrons in graphene, making it promising for various applications.
Researchers have identified promising new drug targets for Huntington's disease, which can stimulate autophagy and alleviate the toxicity of malformed proteins. Candidate drugs include verapamil and clonidine, which have been shown to be safe and effective in cell-based models.
A study published in Nature reveals that the protein REST maintains self-renewal and pluripotency in embryonic stem cells by suppressing a specific microRNA called miR-21. This discovery has implications for regenerative medicine and treating diseases, including pediatric brain cancer.
Researchers at Yerkes National Primate Research Center have identified a unique language feature in the human brain that differs from our closest living relative, the chimpanzee. The study used DTI to compare human brain structures and found a larger and more widespread projection of fibers in the middle temporal lobe.
Researchers at Memorial Sloan-Kettering Cancer Center have successfully used therapeutic cloning to treat Parkinson's disease in mice. The method involves generating customized dopamine neurons from the patient's own skin cells and transplanting them into the mouse, resulting in neurological improvement.
Kansas State University faculty members have contributed to the sequencing of the red flour beetle genome, a breakthrough that will aid research on genetics and insect pest management. The study was led by Stephen Richards at Baylor College of Medicine and involved over 100 scientists from 14 countries.
A Medical College study on pitching mound height provides insight into baseball injuries. The study found that pitchers using a 10-inch mound experience increased stress on the shoulder joint, leading to potential injuries such as rotator cuff tears or labrum damage.
The study reveals that the switch is bistable, maintaining its on state even without external signals, and provides clues for novel drug targets for cancer and other diseases. The findings have implications for understanding cell fate decisions and the process of cell death.
