Hummingbirds: still evolving endless forms most wonderful | @GrrlScientist

by GrrlScientist in GrrlScientist

A new study finds that the rising Andes is tied to the rapid speciation of hummingbirds. This study also predicts that hummingbirds will evolve twice as many species as what we see today.... Read more »

Scientists Determine Most Favorable Wind Turbine Positioning

by dailyfusion in The Daily Fusion

A team of researchers at Johns Hopkins University (JHU) has developed a new way to study wake effects that takes into account the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output....

Hybrid Cars More Fuel-Efficient in China, India Than in U.S.

by dailyfusion in The Daily Fusion

What makes cities in India and China so frustrating to drive in—heavy traffic, aggressive driving style, few freeways—makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab)....

Bioenergy From Forestry Is Not Sustainable Enough for EU

by dailyfusion in The Daily Fusion

The levels of forest residue bioenergy, considered to be sustainable from a forestry perspective, may provide considerable reductions in greenhouse gas emissions in European countries. Still, these reductions fall short of a 60 % threshold planned by the EU. This mismatch may have important climate policy implications.... Read more »

GENETICALLY MODIFIED (GM) CROPS- FRIEND OR FOE?

by Amy Swanston in Antisense Science

With the Council for Science and Technology advising that we need to rethink our stance on GM food, we decided to look into some of the science behind genetic engineering to see what all the fuss is about.

Every year the world population increases, as does our need to find new sources of food. Globally malnutrition affects 34 million children across the world- but could GM crops be the cure? A huge proportion of land is simply not good enough to grow food or has problems with pests, but if we........ Read more »

Humans Made Conchs Shrink (And One Kid Saw It Coming)

by Elizabeth Preston in Inkfish

The classic, swirling shell of a conch helps protect it from hungry birds and sea creatures, but when a human decides to pluck one from shallow water and boil it for supper, there’s not much the animal can do. Its only defense is to evolve, as a species, to be smaller and less appealing to […]The post Humans Made Conchs Shrink (And One Kid Saw It Coming) appeared first on Inkfish.... Read more »
