Climate change threatens fatty acid essential for brain health

Global warming may lead to a drastic reduction in the availability of an essential omega-3 fatty acid that is needed for brain development in mammals, among other things. Docosahexaenoic acid, more commonly called DHA, is primarily acquired from eating seafood and fish, though it can also be acquired from fatty acid supplements. The production of DHA is mostly reliant on … Continue reading

E-bikes are now allowed in US national parks, for better or worse

The next time you visit a National Park in the US, you can likely bring your e-bike with you. The National Park Service has expanded the use of e-bikes to allow pedal assist models on the same roads and trails as conventional bicycles so long as the...

Fast food scraps are giving city birds high cholesterol

It’s no secret that fast food is unhealthy and that may be true for more than just humans. A new study has found that crows located in urban environments are suffering from high cholesterol as a direct consequence of fast food consumption, mirroring the same health condition observed in many humans who frequently eat this high-fat convenience food. Fast food … Continue reading

How fecal transplants may save Australia’s threatened koala population

Fecal transplants are helping expand koala microbiomes, allowing the marsupials to eat a wider range of ...

While fecal transplants are being cautiously explored by mainstream scientists as novel treatments for everything from autism to inflammatory bowel disease, a new study led by University of Queensland researchers is suggesting the technique may help koalas in Australia adapt to new habitats.

The puffy pink seaweed that can stop cows burping methane into the atmosphere

Cows are responsible for a large portion of methane emissions from the agriculture sector, but a ...

Fossil fuels burnt for things like energy and transportation might be the first things that come to mind when considering climate-changing greenhouse gas emissions, but a sizable portion also come from agriculture – around 9 percent, according the EPA. Within that, the methane belched out by the world's cows is a particularly potent contributor, but scientists are preparing alternative diets for these livestock that could cut these harmful emissions out altogether.

Ocean Cleanup attaches parachutes to trash-collecting barriers to maintain steady speeds

The Great Ocean Cleanup team envisions fleets of its U-shaped barrier drifting through the Great Pacific ...

It has been a rocky start to life for The Ocean Cleanup's U-shaped barriers, which it hopes will sweep through the Great Pacific Garbage Patch collecting plastic waste that can be hauled back to shore and recycled. The team is now reporting to have overcome a significant stumbling block, using a novel parachute-anchor mechanism to correct speed-related troubles plaguing its earlier approach to ocean-going garbage collection.

Melting icebergs could play significant role in slowing down warming

A huge iceberg seen from the window of a NASA research plane off the coast of ...

The melting of Antarctic ice sheets is one of the most visceral consequences of climate change, but the full extent of their impact on the cycle remains mostly unknown. Now, researchers from the US and South Korea have run climate simulations that include the "iceberg effect" and found that melting icebergs could play a significant role in slowing warming in the southern hemisphere.
