Searching for habitable exoplanets? Look for phosphorus
Scientists develop a new way to search for potentially habitable exoplanets by measuring the amount of phosphorus in their stars. Such planets should also have abundant phosphorus – necessary for life on Earth – increasing the chances for life.
Rodent ancestors combined portions of blood and venom genes to make pheromones
Experts who study animal pheromones have traced the evolutionary origins of genes that allow mice, rats and other rodents to communicate through smell. The discovery is a clear example of how new genes can evolve through the random chance of molecular tinkering and may make identifying new pheromones easier in future studies. The results represent a genealogy for the exocrine-gland secreting peptide (ESP) gene family.
Volcanic ash could help reduce CO2 associated with climate change
Scientists investigating ways of removing carbon dioxide (CO2) and other greenhouse gases from our atmosphere believe volcanic ash could play an important role.
Global warming, fires, and crime in Mexico and beyond – Brookings Institution
When a brush fire erupted near Tijuana in early September, a large part of the North American western coast was either on fire or at high risk of fire. The dramatic fire belt stretched from Canada to northern Mexico. Although…
How Zika virus degrades essential protein for neurological development via autophagy
Researchers shed new light on how Zika virus hijacks our own cellular machinery to break down an essential protein for neurological development, getting it to ‘eat itself’. By triggering this process known as autophagy, Zika virus is able to degrade an important protein, a process that may contribute to the development of neurological or brain deficiencies and congenital birth defects in the newborns of infected pregnant women.
This Rat Sniffs For Landmines In Cambodia–And Has Just Won A Gold Medal For His Life-Saving Work
A landmine detection rat, whose work in Cambodia has transformed the lives of the country’s citizens, has been awarded the gold medal from a UK charity for his life-saving bravery and devotion to duty. Magawa is an African giant pouched rat, trained to detect landmines by the international non-profit APOPO. He has discovered 39 landmines and […]

Climate Change’s Biggest Joke: Go Vegan, Save The Planet
Sadly, the world already has 1.5 billion vegetarians but only 75 million by choice. The rest can not afford the health-giving protein and fat in meat. As they move out of poverty they will likely happily bring meat into their…
The testimony of trees: How volcanic eruptions shaped 2000 years of world history
Researchers have shown that over the past two thousand years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change.
Coldest Northern Hemisphere temps of minus 69.6 degress Celsius: Greenland, 1991
Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere.
