Blood is a remarkable material: it must remain fluid inside blood vessels, yet clot as quickly as possible outside them, to stop bleeding. The chemical cascade that makes this possible is well understood for vertebrate blood. But hemolymph, the equivalent of blood in insects, has a very different composition, being notably lacking in red blood cells, hemoglobin, and platelets, and having amoeba-like cells called hemocytes instead of white blood cells for immune defense.
Scientists have discovered how female Diadem butterflies have evolved to look like African Queen butterflies to repel predators.
Researchers at the University of Gothenburg warn that today's hunting quotas of about 3,000 animals pose a risk to the long-term survival of the gray seal in the Baltic Sea. The conclusions of this new study are based on statistics from 20th century seal hunting and predictions of future climate change.
ER positive breast cancer is sensitive to hormone estrogen, which means its cells divide and grow with help of this hormone
A TNC-funded expedition has re-discovered a giant rat species not seen by scientists for more that 30 years.
Researchers believe there may be a way to target ‘sleeping’ breast cancer cells and prevent relapse.

Researchers from The Institute of Cancer Research in London found the hormone treatment used to prevent breast cancer from returning causes cells to 'hibernate' instead of dying off.
It is estimated that 30% of the world's terrestrial carbon stocks are found in the boreal forest, 60% of which is below ground. Organic soil horizons contain about one-third of the soil carbon. Therefore, the stability of boreal soils is critical to understanding global carbon cycle feedbacks to climate change and soil management. However, the regulating factors of humus carbon sequestration in the boreal forests globally are not entirely understood.
If two’s company and three’s a crowd, the Great Salt Lake is getting crowded after scientists discovered a species of nematode, known also as a roundworm, making it just the third multicellular animal known to inhabit the lake. Brine shrimp and brine flies were the only other multicellular animals thought to be living in the […]
