The journal “Nature” has reported the world’s only known case of “semi-identical” twins.
Identical twins form when an egg fertilized by one sperm splits, forming two embryos with the same genetic material. Fraternal or non-identical twins form from two eggs fertilized by different sperm, so they share half their genetic material. In this case, the twins were created when one egg divided after being fertilized by two sperm–a rare occurrence. As a result, these twins have identical maternal genes, but only share half their paternal genes.
As an interesting footnote, one of them was found to be a hermaphrodite.

Research shows what I could have told you a long time ago–multitasking reduces productivity. Trying to handle multiple tasks simultaneously only increases the risk you’ll make a mistake and ultimately makes you less effective than you would have been if you’d done one thing at a time.
Multitasking is a curse of the modern age. Remember the tortoise and the hare–slow and steady wins the race.

The boy wizard is set to become the green wizard. For the seventh and final Harry Potter book, HARRY POTTER AND THE DEATHLY HALLOWS, the U.S. publisher, Scholastic, is joining forces with the Rainforest Alliance to make the book’s release eco-friendly.
All copies of the book will contain at least 30% recycled fiber, and 100,000 copies of the “deluxe edition” will be made from recycled paper only in a factory powered by renewable sources. At 784 pages per book, the green publishing plan for DEATHLY HALLOWS will save a lot of trees. Tens of thousands of trees, according to Greenpeace, which lambasted Scholastic two years ago for not using recycled paper to produce the previous Potter book.

So Little Time, So Much to Do

Americans are busy people. Way, way too busy. We’re so busy, we’re too busy to notice that we’re too busy.
A psychiatrist who’s written a book called CRAZYBUSY: OVERSTRETCHED, OVERBOOKED AND ABOUT TO SNAP, ascribes our excessive busy-ness to several factors: communications technology, fear of falling behind, fear of dealing with bigger issues, etc. All these reasons may contribute, but the one I find most likely is: “We do not know how not to be busy.”
I think that’s true. We strive to take on more than we can handle (see March 25 entry on multitasking), and we’re not very good at doing less or doing nothing (see March 14 entry on naps).
So pencil this onto your calendar or add it to your to-do list: “relax and enjoy myself.”
