The Best Season to Get Pregnant 
It's a bizarre correlation: Babies born at certain times of the year are healthier than others. Now, scientists have proven that the phenomenon is real, and they think they know why. The causes are complex, but it's likely that seasonal flu might be to blame. As for the best time to get pregnant? It's during the summer, but don't start trying until June—according to the study, May is the worst month to conceive.
Mom's Antibodies May Cause Some Autism 
Science is still teasing out the different causes of autism, but a new study points to particular antibodies passed from mother to child as the cause in about 25% of autism cases. The researchers behind the study hope to have a diagnostic test to identify these antibodies ready in just 18 months. But some scientists are skeptical. They say that the results of the study are interesting, but much more work needs to be done before a test can be brought to market.
NASA Warned to Go Slow On Asteroid Capture Project 
NASA is forging ahead with plans to kidnap and study a small asteroid, but experts are warning them to proceed with caution, saying that the plan could end in disaster, literal or budgetary. Meanwhile, a scientific panel has given the agency a blueprint for the planned 2020 Mars rover . It looks a lot like Curiosity, except with more features.
Sterilizing Human Waste, No Electricity Required 
How would you sterilize 35 liters of poop? One solution is to toss in some gold nanoparticles, and add a little sunshine and water. This new sterilization technique converts sunlight into steam, no electricity needed. The inventors hope that their new system will soon be used to prevent infections in the developing world and other places where high-tech sterilization can be hard to come by.
Satellites Could Predict Hazards of Glacial Lake Outbursts 
Warming weather is making glacial lake outbursts a lot more common. These mountaintop floods threaten lives and livelihoods, but can be hard to predict because they occur in such remote places. But a new study finds that a simple satellite index can provide a way to identify which lakes are most at risk of causing a damaging flood and destroying communities.
