Secret to Success of Antiviral Gene Uncovered

It's been known for years that humans and other mammals possess an antiviral gene called RSAD2 that prevents a remarkable range of viruses from multiplying. Now, researchers have discovered the secret to the gene's success: The enzyme it codes for generates a compound that stops viruses from replicating. The newly discovered compound, described in the online edition of Nature, offers a novel approach for attacking many disease-causing viruses.

Medical Research And Development In Microgravity

Understanding how and why the human body declines with age and how to slow or prevent it is an extremely important area of research, especially as the older population continues to grow. In addition to providing significant public health benefits, preventing age-related disease could have significant economic impacts on society.

However, aging is difficult to study, as it requires decades and decades of follow-up research. Microgravity offers a solution, as it can serve as a model for accelerated aging. Physiological changes occur approximately 10 times faster in microgravity and it contributes to loss of muscle and bone mass, cardiovascular degeneration, immune deficiency, and optic nerve swelling.

New Insights Of Head Anatomy

Even with a highly skilled neurosurgeon, the most effective anesthesia, and all the other advances of modern medicine, most of us would cringe at the thought of undergoing cranial surgery today. The study was published in World Neurosurgery.

A trepanation the act of scraping, cutting, or drilling an opening into the cranium was practiced around the world, primarily to treat head trauma, but possibly to quell headaches, seizures, and mental illnesses, or even to expel perceived demons.

Brain Analyzes Between Knowledge And Ignorance

Psychologists have discovered our brains use the same algorithm and neural architecture to evaluate the opportunity to gain information, as it does to evaluate rewards like food or money. They have a 'thirst for knowledge' but sometimes' ignorance is bliss', so they choose between this two mindstates at any given time. The study was published in the Proceedings of the National Academy of Sciences, also finds that people will spend money to both obtain advance knowledge of a good upcoming event and to remain ignorant of an upcoming bad event.
