Boys reach sexual maturity younger and younger

male maturity age graph 23456

Male maturity age has shifted again.

Boys are maturing physically earlier than ever before. The age of sexual maturity has been decreasing by about 2.5 months each decade at least since the middle of the 18th century. Joshua Goldstein, director of the Max Planck Institute for Demographic Research in Rostock (MPIDR), has used mortality data to demonstrate this trend, which until now was difficult to decipher. What had already been established for girls now seems to also be true for boys: the time period during which young people are sexually mature but socially not yet considered adults is expanding…

Genius 13-Year-Old has a solar power breakthrough

Would you believe this could be the new look of solar power?

7th grader Aidan Dwyer was walking in the woods during the winter, and looking up, he noticed something about the bare branches above him. They didn’t appear to be growing randomly. So he took some measurements of the angles of the branches, crunched some numbers, and wouldn’t you know it, he found that the ubiquitous Fibonacci Sequence was behind it all. He suspected there was a reason behind this. That trees were using this pattern to gather more light.

So he did an experiment. Using the same number of solar cells, he built two working models. One was a traditional, flat array will all of the panels on a single plane. The other used the Fibonacci Sequence to create the same spiraled pattern he observed in the trees. The results? The little man himself reports…

Alligator fat meets nearly all of the official standards for high-quality biodiesel.

Alligators, in addition to being a novelty food, could also provide a feedstock for biodiesel. The alligator meat industry disposes of about 15 million pounds of alligator fat in landfills every year. Scientists discover the that oil can be extracted from the fat and used to make a high-quality biodiesel.

Amazon grows again.

Amazon is constantly growing and expanding its catalog of videos available for on-demand streaming. The service just reached the 100k mark with 9,000 of those available under the Prime streaming plan. The bulk of the library is set aside for à la carte renting and buying with TV titles starting at $.99 cent and movies for $3.99. With deep living room penetration, all Amazon needs to do is flip the switch, offer a reasonably-priced subscription plan open to all titles, and effectively shut down Netflix…
