Survival differences seen for advanced-stage laryngeal cancer

The five-year survival rate for advanced-stage laryngeal cancer was higher than national levels in a small study at a single academic center performing a high rate of surgical therapy, including a total laryngectomy, or removal of the voice box, to treat the disease, despite a national trend toward organ preservation, according to a report published online by JAMA Otolaryngology-Head & Neck Surgery. —> Read More Here

It’s a well-known fact that Earth’s ozone layer protects us from a great deal of the Sun’s ultra-violet radiation. Were it not for this protective barrier around our planet, chances are our surface would be similar to the rugged and lifeless landscape we observe on Mars.

Beyond this barrier lies another – a series of shields formed by a layer of energetic charged particles that are held in place by the Earth’s magnetic field. Known as the Van Allen radiation belts, this wall prevents the fastest, most energetic electrons from reaching Earth.

And according to new research from NASA’s Van Allen probes, it now appears that these belts may be nearly impenetrable, a finding which could have serious implications for future space exploration and research.(…)

How do Tourette’s patients react to visual stimulation with their own self-image?

Tourette’s syndrome is characterized by tics caused in many by premonitory urges; sensations which give patients compulsion to act to relieve discomfort. Habit reversal therapy conditions patients into heightened awareness of premonitory urges and forced counteraction of the tic. New research examines the effect on Tourette’s sufferers when exposed to their own image for a prolonged period. Could introduction of patients’ self-image reduce tics due to heightened self-awareness and subsequent self-imposed tic control? Or might watching themselves increase inclination to tic? —> Read More Here

Ancient marine algae provides clues of climate change impact on today’s microscopic ocean organisms

A study of ancient marine algae has found that climate change affected their growth and skeleton structure, which has potential significance for today’s equivalent microscopic organisms that play an important role in the world’s oceans. Coccolithophores, a type of marine algae, are prolific in the ocean today and have been for millions of years. These single-celled plankton produce calcite skeletons that are preserved in seafloor sediments after death. Although coccolithophores are microscopic, their abundance makes them key contributors to marine ecosystems and the global carbon cycle. —> Read More Here
