A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous magnetic fields needed to explode the star and fire off bursts of gamma rays visible halfway across the universe. read more
Computer simulations have allowed scientists to work out how a puzzling 555-million-year-old organism with no known modern relatives fed, revealing that some of the first large, complex organisms on Earth formed ecosystems that were much more complex than previously thought. read more
While Canadian Prime Minister Justin Trudeau is in Paris hammering out the details of the global fight against climate change, a new study out of the University of Montreal and the Trottier Energy Institute shows that Canadian attitudes are somewhat ambivalent.
Scientists have discovered a hungry black hole swallowing a star at the centre of a nearby galaxy. read more
Scientists have developed a graphene based microphone nearly 32 times more sensitive than microphones of standard nickel-based construction. read more
Fresh analysis of a reptile fossil is helping scientists solve an evolutionary puzzle – how snakes lost their limbs. read more
Extinct archosaurs’ eggshell porosity may be used as a proxy for predicting covered or exposed nest types, according to a study published November 25, 2015 in the open-access journal PLOS ONE by Kohei Tanaka from the University of Calgary and colleagues.
More than 190 countries are meeting in Paris next week to create a durable framework for addressing climate change and to implement a process to reduce greenhouse gases over time.
This illustration shows Earth surrounded by filaments of dark matter called “hairs.
A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found. read more
Coccolithophores–tiny calcifying plants that are part of the foundation of the marine food web–have been increasing in relative abundance in the North Atlantic over the last 45 years, as carbon input into ocean waters has increased. Their relative abundance has increased 10 times, or by an order of magnitude, during this sampling period. This finding was diametrically opposed to what scientists had expected since coccolithophores make their plates out of calcium carbonate, which is becoming more difficult as the ocean becomes more acidic and pH is reduced
Saharan Africa, dozens of major ‘development corridors,’ including roads, railroads, pipelines, and port facilities, are in the works to increase agricultural production, mineral exports, and economic integration. And, if all goes according to plan, it’s going to be a disaster, say researchers reporting in the Cell Press journal Current Biology on Nov
An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light. read more
New research from the University of Birmingham has shown that progesterone supplements in the first trimester of pregnancy do not improve outcomes in women with a history of unexplained recurrent miscarriages. read more
Stem cells that have been specifically developed for use as clinical therapies are fit for use in patients, an independent study of their genetic make-up suggests.
Stem cell scientists have made a key find that aids the quest to produce therapies for patients with liver damage. read more
After a decade of rapid growth in global CO2 emissions, which increased at an average annual rate of 4%, much smaller increases were registered in 2012 (0.8%), 2013 (1.5%) and 2014 (0.5%). In 2014, when the emissions growth was almost at a standstill, the world’s economy continued to grow by 3%.

Researchers at the University of Georgia have developed a model for evaluating a potential new strategy in the fight against drug-resistant diseases. read more
Scientists have mapped out the genes that keep our cells alive, creating a long-awaited foothold for understanding how our genome works and which genes are crucial in disease like cancer. read more
