When you mention rich ecosystems that are vital for life on Earth, people tend to think of rainforests, but ocean plankton are actually just as crucial. The microscopic beings that drift on the upper layer of the oceans are globally referred to as "plankton"; together they produce half of our oxygen, act as carbon sinks, influence our weather, and serve as the base of the ocean food web that sustains the larger fish and marine mammals that we depend upon or draw delight from.

"Beyond the cutting-edge science that was developed thanks to our collaborative work with the Tara Expéditions Foundation, this adventure is also about showing people all over the world how important the ocean is for our own well-being," says Eric Karsenti, director of Tara Oceans, from EMBL and CNRS.

If you want cheap medicine, Canadian taxpayers make it possible to get a great deal, but when it comes to new medicines, Canada is behind similar countries, according to a new report which ranks it 16th out of 18 comparable OECD countries. 

Only 23% of 141 Health Canada-approved new medicines were included in public plans, ranking Canada 17 out of 18 there. Public drug plans in Canada make new medicines available only on a conditional, case-by-case basis, resulting in more administration, longer wait times for patients before beginning treatment, increased paperwork for physicians and no guarantee that patients will receive coverage.

The report further notes that:

A remote galaxy shining with infrared light equal to more than 300,000,000,000,000 suns has been discovered using data from NASA's Wide-field Infrared Survey Explorer (WISE. The galaxy, belongs to a new class of objects nicknamed extremely luminous infrared galaxies, or ELIRGs.

The galaxy, known as WISE J224607.57-052635.0, may have a behemoth black hole at its belly, gorging itself on gas, but is certainly the most luminous discovered to-date.

Supermassive black holes grow by drawing gas and matter into a disk around them. The disk heats up to beyond-sizzling temperatures of millions of degrees, blasting out high-energy, visible, ultraviolet, and X-ray light. The light is blocked by surrounding cocoons of dust. As the dust heats up, it radiates infrared light.

A new analysis of Ice Age birds has revealed that many of the birds were larger - despite what is commonly believed, the authors say it reflects the richness and greater productivity of the environment in the Ice Age.

They picture an unusual mix of birds in one space, the Middle Palaeolithic (Marine Oxygen Isotope Stage 3) deposits of Pin Hole, Creswell Crags, Derbyshire in England, and a distinct Neanderthal Dawn Chorus.

A new genomic analysis of an ancient Taimyr wolf bone reveals that dogs and humans may have been a match far longer than previously believed.

Earlier genome-based estimates have suggested that the ancestors of modern-day dogs diverged from wolves no more than 16,000 years ago, after the last Ice Age, but new 35,000 year-old radiocarbon dating shows the Taimyr wolf represents the most recent common ancestor of modern wolves and dogs.

Measles needs only a two-dose vaccine during childhood for lifelong immunity while the influenza virus mutates constantly and requires a yearly shot to get even a certain percentage of protection.

What explains that? Surface proteins that the measles virus uses to enter cells are ineffective if they suffer any mutation, meaning that any changes to the virus come at a major cost, according to a new paper.
