NASA's RapidScat, GPM and Terra satellite have been actively providing wind, rain and cloud data to forecasters about Tropical Cyclone Eunice. The storm reached Category 5 status on the Saffir-Simpson scale on January 30.
Tropical cyclone Eunice became the fourth tropical cyclone of the 2015 Southern Indian Ocean season when it formed well east of Madagascar on January 27, 2014.
NWA 7034, a meteorite found a few years ago in the Moroccan desert, is like no other rock ever found on Earth. It's been shown to be a 4.4 billion-year-old chunk of the Martian crust, and according to a new analysis, rocks just like it may cover vast swaths of Mars.
Have we reached peak food? It's certainly becoming a popular claim again, just like it did in the 1960s and all the way back to Thomas Malthus and even earlier. Every time there was a famine, humanity had exceeded technology and we were in peril. Yet science has always bounced back.
Research by scientists and conservationists from the Wildlife Conservation Society, the Zoological Society of London, and other groups published today in PLOS ONE shows that critically endangered Saharan cheetahs exist at incredibly low densities and require vast areas for their conservation. The research also offers some of the world's only photographs of this elusive big cat.
Using whole genomic sequencing, scientists from RIKEN in Japan have for the first time demonstrated the profound effect that chronic hepatitis infection and inflammation can have on the genetic mutations found in tumors of the liver, potentially paving the way to a better understanding of the mechanisms through which these chronic infections can lead to cancer. Primary liver cancer is the third leading cause of cancer death worldwide, and recent studies have shown that particularly in Asia, infection with either hepatitis B or C is often associated with such cancers.
One of nature's fascinating questions is how zebras got their stripes.
A team of life scientists led by UCLA's Brenda Larison has found at least part of the answer: The amount and intensity of striping can be best predicted by the temperature of the environment in which zebras live.
The efficient production of both biofuel and animal feed from one crop is now possible, and can be done on a farm without the need for off-site processes. The research, published in the open access journal Biotechnology for Biofuels, demonstrates the practical potential of an alternative to fossil fuels that does not compete with food resources.
The world's urban areas have experienced significant increases in heat waves over the past 40 years, according to new research published today.
These prolonged periods of extreme hot days have significantly increased in over 200 urban areas across the globe between 1973 and 2012, and have been most prominent in the most recent years on record.
For most of us, switching to a vegetarian diet might be a matter of a New Year's resolution and a fair amount of willpower, but for an entire species, it's a much more involved process -- one that evolutionary biologists have struggled to understand for a long time.
The warm ocean temperatures that brought an endangered green sea turtle to San Francisco in September have triggered a population explosion of bright pink, inch-long sea slugs in tide pools along California's central and northern coastline. The Hopkins' Rose nudibranch, while no strange sight in Southern California, is rarely spotted farther north.
fter 200 million gallons of crude oil spilled into the Gulf of Mexico in April 2010, the government and BP cleanup crews mysteriously had trouble locating all of it.
Now, a new study led by Florida State University Professor of Oceanography Jeff Chanton finds that some 6 million to 10 million gallons are buried in the sediment on the Gulf floor, about 62 miles southeast of the Mississippi Delta.
Building a protein is a lot like a telephone list: information is passed along from one messenger to another and with that comes the potential for errors in each step. There are separate, specialized enzymatic machines that proofread at each step, ensuring that the instructions encoded in our DNA are faithfully translated into proteins.
A collaboration of researchers have experimentally produced Möbius strips from the polarization of light, confirming a theoretical prediction that it is possible for light's electromagnetic field to assume this peculiar shape.
Möbius strips are easy to create. Take a strip of paper, twist it once and join up the ends. That's it, you have created a Möbius strip: a three dimensional structure that has only one side. Millions of school children do exactly this in classrooms every year. But finding Möbius strips occurring naturally is another issue.
The Great Lakes have been invaded by more non-native species than any other freshwater ecosystem in the world. In spite of increasing efforts to stem the tide of invasion threats, the lakes remain vulnerable, according to scientists from McGill University and colleagues in Canada and the United States. If no new regulations are enforced, they predict new waves of invasions and identify some species that could invade the Lakes over the next 50 years.
While it is widely accepted that the origins of modern humans date back some 200,000 years to Africa, there has been furious debate as to which model of early Homo sapiens migration most plausibly led to the population of the planet -- and the eventual extinction of Neanderthals.
