Life could have emerged from lakes with high phosphorus

Life as we know it requires phosphorus, and lots of it. But phosphorus is scarce. A new study reports that certain types of carbonate-rich lakes, which could have formed on early Earth, have the right chemistry to keep phosphorous levels high and available to organisms.

Many younger patients with stomach cancer have a distinct disease

Many people under 60 who develop stomach cancer have a 'genetically and clinically distinct' disease, new research has discovered. Compared to stomach cancer in older adults, this new, early onset form often grows and spreads more quickly, has a worse prognosis, and is more resistant to traditional chemotherapy treatments, the study finds.

Learning from the bears

Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. Researchers report on how they manage to do this. The grizzly bears' strategy could help prevent muscle atrophy in humans as well.

Scientists link La Niña climate cycle to increased diarrhea

A study finds that spikes in cases of life-threatening diarrhea in young children are associated with La Niña climate conditions. The findings could provide the basis for an early-warning system that would allow public health officials to prepare for periods of increased diarrhea cases as long as seven months ahead of time.

North Atlantic Current may cease temporarily in the next century

The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations showed that there is a 15 percent likelihood that there will be a temporary change in the current in the...

How cells learn to 'count'

One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes.
