Science News Weekly Round Up
By: Ryan Wheaton
As a Production Assistant for SCIENCE, I send out an email to the rest of the team wrapping up big stories in science-related news every Friday. It helps us keep on top of what's going on in the world around us. We hope it helps you all too.

Self-Portraits of a Declining Brain
"He died in 2007, but really he was dead long before that," explains the bright-eyed woman to a room full of sympathetic listeners. "Bill died in 2000, when the disease meant he was no longer able to draw." See the whole story.
Societal Control of Sugar Essential to Ease Public Health Burden, Experts Urge
Sugar should be controlled like alcohol and tobacco to protect public health, according to a team of UCSF researchers, who maintain in a new report that sugar is fueling a global obesity pandemic, contributing to 35 million deaths annually worldwide from non-communicable diseases like diabetes, heart disease and cancer.

Taking the Long View on the World's Energy Supplies
Now a handful of researchers are warning that energy sources we normally think of as innocuous could affect the planet's climate too. If we start to extract immense amounts of power from the wind, for instance, it will have an impact on how warmth and water move around the planet, and thus on temperatures and rainfall.

Can't Find Your Keys? Your Brain's Out of Sync
You're running late for work and you can't find your keys. What's really annoying is that in your frantic search, you pick up and move them without realizing. This may be because the brain systems involved in the task are working at different speeds, with the system responsible for perception unable to keep pace. See the whole story.
Earth in for a Bumpy Ride as Solar Storms Hit
The sun is gearing up for a peak in activity at a time when technology makes our planet more vulnerable to solar outbursts than ever before. Monitoring has improved since the last solar maximum, so what are the big risks this time around? See the whole story.
Global Experts Question Claims About Jellyfish Populations
Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations — clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants — and recent media reports have created a perception that the world's oceans are experiencing increases in jellyfish due to human activities such as global warming and overharvesting of fish. See the whole story.
First Plants Caused Ice Age, New Research Reveals
New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published in Nature Geoscience. See the whole story.
Scientists Decode Brain Waves to Eavesdrop On What We Hear
Neuroscientists may one day be able to hear the imagined speech of a patient unable to speak due to stroke or paralysis, according to University of California, Berkeley, researchers. See the whole story.
Stellar Nursery: A Pocket of Star Formation
A new view shows a stellar nursery called NGC 3324. It was taken using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. The intense ultraviolet radiation from several of NGC 3324's hot young stars causes the gas cloud to glow with rich colours and has carved out a cavity in the surrounding gas and dust.

Mouse to Elephant? Just Wait 24 Million Generations
Scientists have for the first time measured how fast large-scale evolution can occur in mammals, showing it takes 24 million generations for a mouse-sized animal to evolve to the size of an elephant. See the whole story.
