Friday Roundup: Sex, math, sugar bombs, and vocal fry

Via Wikimedia Commons. This is a picture of a whole lot of sugar.

Women and men and science

• Vocal fry: I (Emily) am a biologist. This phrase makes me think of tiny, loudmouthed fish. But it's really about a vocal tic. Do you do this when you speak? It’s all the rage among young XXers these days.
• Decaying hoods, premature birth: living in among dilapidated buildings linked to higher risk of premature childbirth. 
• Do you know when you want it? Yes, that It. 
• Women can do math. Yep, as well as men. Or maybe we should write that as, Men can do math. Yep, as well as women.
• Male circumcision: the controversy continues. Does it or doesn't it stem the transmission of AIDS?

Cool, cute, crazy sci stuff

Baby sloths.Cuuuute baby sloths.

• More evidence of water on Mars: mineral deposits that only water could have made
• minerals deposited by water on Mars
• In his own hand, his own, awesome genius hand: Newton's Principia available for virtual viewing.

Science education

• New standards for teaching chemistry. 
• Speaking of chemistry, have you heard what the relationship is among chemistry, alchemy, and urine?

Science and health

• How much federal money are we wasting on investigations of alternative health and medicine. Example: Coffee enemas for pancreatic cancer (!).
• Cereal offenders: How do we get the sugar out of breakfast cereal? We’re thinking it’ll take a shovel.
• No raw cookie dough! Can we say it enough? No. Raw. Cookie. Dough. 
• Vit D not miracle preventative for heart attacks or cancer. Evidently, there are some things that vitamin D cannot do.
