Three of the most important crops yields produced in the United States (corn, soybeans, and cotton) are predicted to plummet if temperatures rises due to climate change continue.

Satellites spying on Typhoon Vamco have obtained data confirming that the large storm has a huge eye, about 45 miles in diameter. Like its cousin Hurricane Bill, Vamco is a very stubborn storm system that continues to linger.
Predatory crustaceans of the class Remipedia rely on long antennae which search the lightless deep oceans in all directions. Like some type of science fiction monster, their head is equipped with powerful prehensile limbs and poisonous fangs.
The first season of the international drilling project NEEM (North Greenland Eemian Ice Drilling) in north-western Greenland was completed on August 20th. A research team, with the participation of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, has drilled an ice core of 1,757.87 m length on the Greenland inland ice within 110 days. It is expected to contain data on climate history of about 38,000 years.
Bill is still holding onto hurricane status near Nova Scotia, and will be bringing a lot of rain and heavy surf to Nova Scotia, Prince Edward Island, and Newfoundland. Today, Sunday, August 23, NASA infrared satellite imagery revealed cold high thunderstorm clouds around Bill's eye, indicating there is still some powerful convection and strong thunderstorms happening in the storm.
With a very lucky shot, scientists have captured a one-second image and the electrical fingerprint of huge lightning that flowed 40 miles upward from the top of a storm. These rarely seen, highly charged meteorological events are known as gigantic jets, and they flash up to the lower levels of space, or ionosphere.
While they don't occur every time there is lightning, they are substantially larger than their downward striking cousins.
Why do some plants blossom even when days are short and gray? Scientists at the Max Planck Institute for Developmental Biology have found the answer to this question: An endogenous mechanism allows them to flower in the absence of external influences such as long days. A small piece of RNA, a so-called microRNA, has a central role in this process, as a decline of its concentration in the shoot apex triggers flowering.
WEST LAFAYETTE, Ind. - Urban workers could suffer most from climate change as the cost of food drives them into poverty, according to a new study that quantifies the effects of climate on the world's poor populations.
A team led by Purdue University researchers examined the potential economic influence of adverse climate events, such as heat waves, drought and heavy rains, on those in 16 developing countries. Urban workers in Bangladesh, Mexico and Zambia were found to be the most at risk.
A new study supported by the World Bank has for the first time tried to combine, understand and predict the effects of climate change on food prices and wages in developing countries to assess how badly different socio-economic strata in sixteen vulnerable countries will be hit by extreme weather conditions, associated with climate change such as annual-scale hot, dry and wet extremes.

Scientists at Climate Central have analyzed climate change projections made with global climate models. Literature based on these models anticipates much more frequent occurrences of hot days, "heat waves," and extremely warm summer seasons. These projected increases in extreme heat will have important societal impacts, including:
New UBC research has literally and figuratively poked holes in single-band Hubbard physics--a model that has been used to predict and calculate the behavior of high-temperature superconductors for 20 years.
The findings were published in the journal Physical Review Letters, and the findings are compelling evidence challenging the model under certain conditions, and could necessitate entirely new theoretical approaches to explaining superconductivity in cuprate materials, one of the outstanding mysteries in condensed-matter physics.
CORVALLIS, Ore. – A team of scientists from Oregon State University has created the first global three-dimensional map of electrical conductivity in the Earth's mantle and their model suggests that that enhanced conductivity in certain areas of the mantle may signal the presence of water.
A non-toxic and environmentally friendly way to make tiny nanorods of zinc oxide has been developed for the first time by researchers in Saudi Arabia. The approach, described in the current issue of the International Journal of Nanoparticles, could allow the nanorods to be used safely in medical and for other applications.
Research at Virginia Tech has shown that the oldest complex life forms -- which lived in nutrient-rich oceans more than 540 million years ago -- likely ate through osmosis.
