Does mountaintop removal also remove rattlesnakes?

Ecology
  On the Cumberland Plateau in eastern Kentucky, surface coal mining is destroying ridgelines and mountaintops, and along with them, the habitat of a surprisingly gentle reptile species – the timber rattlesnake. “Timber rattlesnakes may be the most docile, calm animals of their size in eastern US forests,” Thomas Maigret, ...

Is habitat restoration actually killing plants in the California wildlands?

More Science
In 2014, plant biologists with the California Department of Agriculture reported an alarming discovery: native wildflowers and herbs, grown in nurseries and then planted in ecological restoration sites around California, were infected with Phytophthora tentaculata, a deadly exotic plant pathogen that causes root and stem rot. While ecologists have long ...

The immune system’s fountain of youth

More Science
If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future. The results of this research, led by Prof. Valery Krizhanovsky ...

Some tensions are good for life

More Science
Like every animal has its characteristic size and shape, each cell type in our body has a size and shape. Neuron (nerve cell) is very different from muscle cells that are dramatically different from the cells in the bone. All these cells look different, perform diverse activities, share things with ...

World’s fastest STT-MRAM

Engineering
A research team, led by Professor Tetsuo Endoh at Tohoku University, has successfully developed 128Mb-density STT-MRAM (spin-transfer torque magnetoresistive random access memory) with a write speed of 14 ns for use in embedded memory applications, such as cache in IOT and AI. This is currently the world’s fastest write speed ...

  • Are we doomed to repeat prehistoric vegetation loss? 2018-09-08
    Unless we reduce greenhouse gas emissions, the current warming from climate change may drive a dramatic shift in vegetation within the next 100-150 years, according to new research. The change could match the one seen as the last ice age came to an end and the planet warmed, researchers say. “We found that ecosystems all […]
  • Reserve half of Earth for wildlife? Not so fast 2018-09-07
    While some scientists have suggested we need to protect half of Earth’s surface to preserve most of its species, new research indicates that quality, not just quantity, is vital for effective conservation efforts. “There’s a lot of discussion about protecting ‘Half Earth’ as a minimum to protect biodiversity. The challenge is, which half do we […]
