Fructose sugar makes maturing human fat cells fatter, less insulin-sensitive
Fructose, the sugar widely used as high-fructose corn syrup in soft drinks and processed foods, often gets some of the blame for the widespread rise in obesity.
Metabolic syndrome in living kidney donors worsens function of remaining kidney
People who donate one of their kidneys experience faster deterioration of their other kidney if they have the metabolic syndrome at the time of donation, a new study finds.

Research on stem cells wins first prize for Hebrew University researcher
World-recognized discoveries in the study and manipulation of human embryonic stem cells have won first prize in a prestigious applied research competition for a Hebrew University of Jerusalem researcher.
Penn bioengineers create simulator to test blood platelets in virtual heart attacks
A team of bioengineers from the University of Pennsylvania Institute for Medicine and Engineering have trained a computer neural network model to accurately predict how blood platelets would respond to complex conditions found during a heart attack or stroke.
Caltech geologist investigates canyon carved in just 3 days in Texas flood
In the summer of 2002, a week of heavy rains in Central Texas caused Canyon Lake -- the reservoir of the Canyon Dam -- to flood over its spillway and down the Guadalupe River Valley in a planned diversion to save the dam from catastrophic failure.

Now Playing: TED Radio Hour

Anthropomorphic
Do animals grieve? Do they have language or consciousness? For a long time, scientists resisted the urge to look for human qualities in animals. This hour, TED speakers explore how that is changing. Guests include biological anthropologist Barbara King, dolphin researcher Denise Herzing, primatologist Frans de Waal, and ecologist Carl Safina.

#532 A Class Conversation
This week we take a look at the sociology of class. What factors create and impact class? How do we try and study it? How does class play out differently in different countries like the US and the UK? How does it impact the political system? We talk with Daniel Laurison, Assistant Professor of Sociology at Swarthmore College and coauthor of the book "The Class Ceiling: Why it Pays to be Privileged", about class and its impacts on people and our systems.
