Freely available risk model for hurricanes, tropical cyclones      (via sciencedaily.com)     Original source 

As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.

Do hummingbirds drink alcohol? More often than you think      (via sciencedaily.com)     Original source 

Animals that eat fruit or sip nectar often ingest alcohol because naturally occurring yeasts turning sugar into ethanol. But how do animals feel about that? A new study details an experiment to determine whether hummingbirds are turned off by alcohol in sugar water. At 1% by volume, no. At 2% by volume, they consume much less. The implication is that hummingbirds have adjusted to small amounts of alcohol likely present in flowers and backyard feeders.

Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate      (via sciencedaily.com)     Original source 

A team of scientists has observed past episodic intraplate magmatism and corroborated the existence of a partial melt channel at the base of the Cocos Plate. Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events -- and persisting today.

Navigating underground with cosmic-ray muons      (via sciencedaily.com)     Original source 

Superfast, subatomic-sized particles called muons have been used to wirelessly navigate underground in a reportedly world first. By using muon-detecting ground stations synchronized with an underground muon-detecting receiver, researchers were able to calculate the receiver's position in the basement of a six-story building. As GPS cannot penetrate rock or water, this new technology could be used in future search and rescue efforts, to monitor undersea volcanoes, and guide autonomous vehicles underground and underwater.

We've pumped so much groundwater that we've nudged Earth's spin      (via sciencedaily.com)     Original source 

By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study.

Earth was created much faster than we thought: This makes the chance of finding other habitable planets in the Universe more likely      (via sciencedaily.com)     Original source 

Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that water and other essential ingredients for life were delivered to Earth very early on.

The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark      (via sciencedaily.com)     Original source 

A survey of groundwater samples drawn from aquifers beneath more than 80,000 square miles of Canadian prairie reveals ancient groundwaters harbor not only diverse and active microbial communities, but also unexpectedly large numbers of microbial cells. Strikingly, some of these microbes seem to produce 'dark oxygen' (in the absence of sunlight) in such abundance that the oxygen may nourish not only those microbes, but may leak into the environment and support other oxygen-reliant microbes that can't produce it themselves.

Plate tectonics not required for the emergence of life      (via sciencedaily.com)     Original source 

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that harbor life, the planets do not necessarily need to have plate tectonics,' says the lead author of a new paper.

Octopuses rewire their brains to adapt to seasonal temperature shifts      (via sciencedaily.com)     Original source 

Octopuses don't thermoregulate, so their powerful brains are exposed to -- and potentially threatened by -- changes in temperature. Researchers report that two-spot octopuses adapt to seasonal temperature shifts by producing different neural proteins under warm versus cool conditions. The octopuses achieve this by editing their RNA, the messenger molecule between DNA and proteins. This rewiring likely protects their brains, and the researchers suspect that this unusual strategy is used widely amongst octopuses and squid.

When pigeons dream      (via sciencedaily.com)     Original source 

Dreams have been considered a hallmark of human sleep for a long time. Latest findings, however, suggest that when pigeons sleep, they might experience visions of flight. Researchers studied brain activation patterns in sleeping pigeons, using functional magnetic resonance imaging. The study revealed that similar to mammals, most of the brain is highly active during REM sleep. However, this wake-like state might come at a cost of reduced waste removal from the brain.
