Biologists Turn Back the Clock to Understand Evolution of Sex Differences

Published: May 3, 2012.
By McGill University

Sex differences account for some of the most of the spectacular traits in nature: the wild colours of male guppies, the plumage of peacocks, tusks on walruses and antlers on moose. Sexual conflict – the battle between males and females over mating – is thought to be a particularly potent force in driving the evolution traits that differ in males and females.

Reducing Water Scarcity Possible by 2050
Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries in 2016.
Walking Fish Reveal How Our Ancestors Evolved Onto Land
About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.
Black Carbon - a Major Climate Pollutant - Also Linked to Cardiovascular Health
Black carbon pollutants from wood smoke are known to trap heat near the earth's surface and warm the climate. A new study led by McGill Professor Jill Baumgartner suggests that black carbon may also increase women's risk of cardiovascular disease.
Global Warming 'Pause' Since 1998 Reflects Natural Fluctuation
Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research by McGill University physics professor Shaun Lovejoy.
Radio-burst Discovery Deepens Astrophysics Mystery
The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescope in Puerto Rico provides important new evidence of mysterious pulses that appear to come from deep in outer space.
Scientists Find Important Piece in the Brain Tumor Puzzle
Scientists at the Montreal Neurological Institute and Hospital, McGill University and McGill University Health Centre have shown that a member of the protein family known as SUMO (small ubiquitin-like modifier) is a key to why tumour cells multiply uncontrollably, especially in the case of glioblastoma. The SUMO family proteins modify other proteins and the SUMOylation of proteins are critical for many cellular processes. Identifying SUMO's role in the cancer cell growth will lead to a new strategy for glioblastoma treatment. …
