A cancer drug could be made 50 times more effective by a chemical found in stinging nettles and ants, new research finds. Researchers at the University of Warwick found that when the chemical, Sodium Formate, is used in combination with a metal-based cancer treatment it can greatly increase its ability to shut down cancer cells.

Governments and donors must pay more attention to the environmental impact of road networks to limit their “devastating” effect on ecosystems, a study on global infrastructure expansion has warned. Road construction opens a “Pandora’s box” of negative impact, according to the authors of the paper, published this month in Current Biology. These include deforestation, animals hunted to extinction, land grabs by speculators betting on development, and wildfires. 

Arctic sea ice shrank to the lowest winter extent ever recorded, according to data released today by the US-based National Snow and Ice Data Center. The record-low ice level follows earlier news that 2014 was the warmest year since record keeping began.
 
An unusually warm February in parts of Alaska and Russia contributed to the record ice low. The winter reach of Arctic ice decreased 1.1 million square kilometres compared to the average maximum from 1981 to 2010. This represents an area more than twice the size of Sweden.
 
"This is not a record to be proud of. Low sea ice can create a series of reactions that further threaten the Arctic and the rest of the globe," said Alexander Shestakov, Director, WWF Global Arctic Programme.

A new study “provides evidence that methane seeps are island-like habitats that harbor distinct microbial communities unique from other seafloor ecosystems." These seeps play an important role in microbial biodiversity of the sea floor.

Methane seeps are natural gas leaks in the sea floor that emit methane into the water. Microorganisms that live on or near these seeps can use the methane as a food source, preventing the gas from collecting in the surrounding hydrosphere or migrating into the atmosphere.

“Marine environments are a potentially huge source for methane outputs to the atmosphere, but the surrounding microbes keep things in check by eating 75 percent of the methane before it gets to the atmosphere. These organisms are an important part of the underwater ecosystem, particularly as it relates to global gas cycles that are climate important in terms of greenhouse gas emissions,” said University of Delaware assistant professor of marine biosciences, Jennifer Biddle.

Uplift associated with the Great Rift Valley of East Africa and the environmental changes it produced have puzzled scientists for decades because the timing and starting elevation have been poorly constrained.​

Now paleontologists have tapped a fossil from the most precisely dated beaked whale in the world - and the only stranded whale ever found so far inland on the African continent - to pinpoint for the first time a date when East Africa's mysterious elevation began.

The 17 million-year-old fossil is from the beaked Ziphiidae whale family. It was discovered 740 kilometers inland at an elevation of 620 meters in modern Kenya's harsh desert region, said vertebrate paleontologist Louis L. Jacobs, Southern Methodist University, Dallas.

Circus elephants just scored a victory with an announcement that Ringling Bros. will be retiring its performers, but big cats and other wild animals left behind may get their own victory in Pennsylvania if a state senator can get them banned.

The emotional and physical toll life on the road as performers takes on elephants has taken center stage, but for other species like big cats, life in the entertainment industry is just as bad.

Zoos and aquariums around the world have a crucial role to play in helping people understand how they can protect animals and their natural habitats, new research from the University of Warwick, the World Association of Zoos and Aquariums (WAZA) and Chester Zoo has found.

In a world first, a research team including James Cook University scientists has discovered how geckos manage to stay clean, even in dusty deserts. 

The process, described in Interface, the prestigious journal of the Royal Society, may also turn out to have important human applications. 

JCU's Professor Lin Schwarzkopf said the group found that tiny droplets of water on geckos, for instance from condensing dew, come into contact with hundreds of thousands of extremely small hair-like spines that cover the animals' bodies. 

If you’re looking for love and there are ten bars in town, your chance of meeting someone is 10 per cent.  In a town with only one bar, your odds are 100 per cent. The same thing happens in nature and is called landmarking. Butterflies and other species find mates by gathering at easily identifiable locations such as the tallest tree or mountain.

Wonderful news! Ten baby tortoises have been spotted on the Galapagos island of Pinzón, in Ecuador. This might not seem like such a big deal–after all, aren’t the Galapagos famous for their tortoises? But in this case, it’s been more than 100 years since the last baby tortoise was seen on Pinzón. Sadly, it was human activity that brought these cute animals to the brink of extinction. Sailors first arrived on Pinzón Island in the mid-18th century, bringing with them on their boats numerous rats that quickly gained a foothold in the fragile ecosystem, feasting on the eggs and hatchlings of the island’s tortoises who, up until then, had few natural predators.
