Hundreds of Andean bird species at risk due to deforestation: New research shows how to protect them      (via sciencedaily.com)     Original source 

Birds native to the tropical Andes are threatened by increasing agricultural development in the region. A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.

Coffee offers performance boost for concrete      (via sciencedaily.com)     Original source 

Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a 'double shot' at life and reduce waste going to landfills. The team developed a technique to make concrete 30% stronger by turning waste coffee grounds into biochar, using a low-energy process without oxygen at 350 degrees Celsius.

Did sabertooth tigers purr or roar?      (via sciencedaily.com)     Original source 

When a sabertooth tiger called out, what noise did it make -- a mighty roar or a throaty purr? A new study examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought -- and that it could depend on the shape of a few small bones.

Transforming flies into degradable plastics      (via sciencedaily.com)     Original source 

Imagine using insects as a source of chemicals to make plastics that can biodegrade later -- with the help of that very same type of bug. That concept is closer to reality than you might expect. Researchers will describe their progress to date, including the isolation and purification of the insect-derived chemicals and their conversion into their bioplastics.

3D-printed vegan seafood could someday be what's for dinner      (via sciencedaily.com)     Original source 

More mock seafood options are needed because of unsustainable fishing and aquaculture practices, which can harm the environment. Now, researchers have a new approach for creating desirable vegan seafood mimics that taste good, while maintaining the healthful profile of real fish. They 3D-printed an ink made from microalgae protein and mung bean protein, and their proof-of-concept calamari rings were air-fried into a snack.

Tattoo technique transfers gold nanopatterns onto live cells      (via sciencedaily.com) 

For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting that they have developed a proof-of-concept technique to 'tattoo' living cells and tissues with flexible arrays of gold nanodots and nanowires. With further refinement, this method could eventually be used to integrate smart devices with living tissue for biomedical applications, such as bionics and biosensing.

The 'unknome': A database of human genes we know almost nothing about      (via sciencedaily.com)     Original source 

Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.
