| How Earth might have looked: How a failed Saharan Atlantic Ocean rift zone sculped Africa's margin Posted: 28 Feb 2014 06:05 PM PST Break-up of the supercontinent Gondwana about 130 Million years ago could have led to a completely different shape of the African and South American continent with an ocean south of today's Sahara desert, as geoscientists have shown through the use of sophisticated plate tectonic and three-dimensional numerical modelling.  |
| Fossilized human feces from 14th century contain antibiotic resistance genes Posted: 27 Feb 2014 01:45 PM PST A team of French investigators has discovered viruses containing genes for antibiotic resistance in a fossilized fecal sample from 14th century Belgium, long before antibiotics were used in medicine.  |
| 'Oddball science' has proven worth, biologists say Posted: 27 Feb 2014 09:55 AM PST Scoffing at or cutting funds for basic biological research on unusual animal adaptations from Gila monster venom to snail sex, though politically appealing to some, is short-sighted and only makes it more likely that important economic and social benefits will be missed in the long run, say a group of evolutionary biologists.  |
| Posted: 27 Feb 2014 09:55 AM PST Plankton in the Earth's oceans received a huge boost when microorganisms capable of creating soluble nitrogen 'fertilizer' directly from the atmosphere diversified and spread throughout the open ocean. This event occurred at around 800 million years ago and it changed forever how carbon was cycled in the ocean.  |
| Posted: 27 Feb 2014 08:55 AM PST A new modeling study suggests that a recent observed increase in summer sea-ice cover in Antarctica's Ross Sea is likely short-lived, with the area projected to lose more than half its summer sea ice by 2050 and more than three quarters by 2100. These changes will significantly impact marine life in what is one of the world's most productive and unspoiled marine ecosystems.  |
| Climate change: No warming hiatus for extreme hot temperatures Posted: 26 Feb 2014 01:53 PM PST While there are claims that there has been a hiatus in global average temperatures, no such hiatus has occurred at the extreme end of the temperature spectrum. New research shows extremely hot temperatures over land have dramatically and unequivocally increased in number and area despite claims that the rise in global average temperatures has slowed over the past 10 to 20 years.  |
