Researchers discovered that oligodendrocytes, responsible for white matter protection, are vulnerable to elevated levels of glutamate after brain or spinal cord injury. Compounds that block glutamate's action may prevent this damage and improve day-to-day function for people with spinal cord injuries.
A European epidemiological study found a weak but significant association between certain factors and sporadic CJD, including consumption of raw meat or brain tissue. The researchers noted that the study is only a first step and many questions remain to be answered.
A team of microbiologists genetically altered Pseudomonas aeruginosa to break its resistance to detergents and antibiotics. The study found that disabling the lasI gene reduced the bacteria's ability to form deadly biofilms.
Researchers aim to detect microorganisms like Cryptosporidium and Giardia before they reach tap water, using pilot-scale treatment systems and advanced detection methods. The study will help evaluate new technologies like dissolved air flotation and microfiltration to ensure public safety.
Researchers at Arizona State University have created a cell-like machine that captures light energy and converts it into a usable form, duplicating biological photosynthesis. This breakthrough technology has the potential to power artificial biological systems and could lead to innovations in computing, drug development, and other fields.
Researchers at Washington University in St. Louis studied 82 healthy adults aged 64-83 over 12 years, finding that most remained stable and only 40% developed cognitive deterioration. The study's key findings suggest that subtle changes in performance can signal the onset of Alzheimer's disease, potentially leading to early intervention.
