We summarize the week's scientific breakthroughs every Thursday.

Sociologists looking at risky behavior plunge into the gene pool
A new study of youths reveals that social scientists’ opinions still vary on the potential of studying how genes interact with social contexts.
- Astronomy
Celestial wish list
A panel of astronomers ranks proposed astrophysics projects for the coming decade.
- Humans
Protecting innocent — and not so innocent — bystanders
Technique removes pedestrians from Google Street View images.

Want a baby? Relax . . .
Scientists have just confirmed what obstetricians knew anecdotally for years — that women under stress can have a difficult time getting pregnant. What’s new: Biochemical markers quantified the degree of stress — and potentially the type — affecting fertility.

The people’s pulsar
Thousands of volunteers help discover a neutron star by donating the processing power in their idle home computers.

Research trials pose challenge to medical privacy
How — or even whether — to share a medical data collected on research subjects poses a growing dilemma. Certainly, doctors would benefit from knowing if their patients had been receiving medicines, physical therapies or dietary supplements. Or if a patient had a history of drug abuse, mental illness, sexually transmitted diseases or engaging in risky behaviors. But in the wrong hands, such sensitive data could compromise an individual’s ability to keep a job — even retain shared custody rights to children during a contentious divorce.

Delivering a knockout
Scientists have finally succeeded in genetically engineering rats.
- Archaeology
Lucy’s kind used stone tools to butcher animals
Animal bones found in East Africa show the oldest signs of stone-tool use and meat eating by hominids.

Spindles foster sound slumber
In “a very clever study,” researchers show that distinctive brain signals help sustain sleep in noisy environments.

‘Miracle’ tomato turns sour foods sweet
Pucker no more: That seems to be one objective of research underway at a host of Japanese universities. For the past several years, they’ve been developing bio-production systems to inexpensively churn out loads of miraculin — a natural taste-altering protein that makes sour foods seem oh so sweet. Their newest biotech reactor: grape tomatoes.

Chicken poses significant drug-resistant Salmonella threat
More than one-in-five retail samples of raw chicken collected in Pennsylvania hosted Salmonella, a new study found — twice the prevalence reported in a 2007 U.S. Food and Drug Administration survey. And where the bacteria were present, more than half were immune to the germicidal activity of at least one antibiotic. Nearly one-third were resistant to three or more.

Gene licensing stifles R&D
Making research findings private property can stymie innovation down the road, a new study finds.
