Journal Club: Simple model reproduces patterns of toxic protein buildup across multiple neurodegenerative diseases

Posted on October 26, 2018 by Jessica P. Johnson

Fatal neurodegenerative diseases including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS) begin as tiny pockets of misfolded proteins that evade the body’s normal detritus-removal systems. They spread throughout the brain and clog neural pathways. But exactly how these proteins propagate … Continue reading →

Journal Club: Aerosols, global warming may dampen cyclone activity in some regions

Posted on October 6, 2017 by Charles Choi

A recent study suggests that human activity may have decreased the number of tropical cyclones in the western North Pacific. A separate study predicts that the total number of intense tropical cyclones will decrease globally in the decades to come, … Continue reading →

Journal Club: Potential life could have spread with relative ease amongst newly-discovered group of seven exoplanets

Posted on March 10, 2017 by Adam Mann

The odds of life spreading between the worlds of the newly-discovered seven-planet TRAPPIST-1 system are up to 1,000 times greater than in our own solar system. That’s the conclusion of a new analysis posted March 2 to the arXiv, an … Continue reading →

Journal Club: Shark blood compound offers up novel mechanism for stabilizing folded proteins

Posted on March 7, 2017 by Jessica P. Johnson

Sharks and other sea life often maintain high levels of trimethylamine N-oxide (TMAO) in their blood, a compound vital to their surviving in the saline environment. TMAO helps maintain an osmotic balance between body tissues and sea water to prevent … Continue reading →

Journal Club: Why do trees fix nitrogen in certain forests and not others? Model offers insights with big implications for the biosphere

Posted on December 14, 2015 by Charles Choi

Many trees can generate their own fertilizer from nitrogen in the air. But it remains a mystery as to why they grow where they do – for example, few grow in the nitrogen-poor soils of temperate forests but many thrive … Continue reading →

Water, water everywhere, but not enough to farm

Posted on February 4, 2013 by pnas

Based on human population growth over the last two millennia, Heinz von Foerster and colleagues famously predicted that our population would approach infinity on Friday, 13 November, 2026. Of course, the 1960 doomsday calculation required paradisiacal conditions, including an unlimited … Continue reading →
