Darcin helps mice remember where scent marks are
Scent marks, or the odors that mammals leave behind to mark their territory, contain cocktails of chemicals that pass on information about the animal's gender and social status. Animals regularly revisit scent marks to get more information about the creature leaving them, but until now researchers have not known how animals relocate these scent marks days or even weeks after first finding them.

Preparing for what can't be prepared for
Even as an organizer of Moody's Mega Math Challenge began explaining to an inquiring audience how students can prepare for the Internet-based math modeling competition, long-time judge David Sprecher, professor emeritus at UC Santa Barbara, exclaimed, "But you can't prepare!" Interestingly, both perspectives accurately define the Challenge in which thousands of high school juniors and seniors from 29 states will compete on March 2-3, 2013, for scholarship awards totaling $115,000.

Donation made possible by UH allows visually impaired child to read
For the third year, a children's vision alliance is teaming up at the University of Houston to provide life-changing assistance to a visually impaired child in need. A nine-year-old boy with a rare disorder that results in rapid loss of vision will receive an electronic video magnifier thanks to an alliance between the Center for Sight Enhancement at UH's College of Optometry and two partner organizations, Optelec and Sight Savers America.

Pioneering cochlear implant patient returns to encourage others
The first person to receive a cochlear implant through the UT Dallas Callier Center for Communication Disorders returned to share his experiences with younger patients. Michael was 15 months old when doctors offered their grim prognosis. He would never hear, and he would probably never be able to read or communicate beyond the level of a third-grader. "I'm very glad that I was able to prove them wrong," Noble said recently.

How do moths choose their flowers?
Have you ever wondered how moths know which flowers to visit for nectar? A new study shows that a particular kind of moth -- the hawkmoth -- has specific patterns of brain activity for flower odors that it is naturally attracted to. On top of that, these moths can learn to associate new odors with nectar without forgetting their original, natural preferences, according to researchers.

Blowing bubbles
Astronomers have captured a very special event in space: a so-called "reborn planetary nebula." This is a gas bubble inside a previously blown bubble, or nebula, like you can see in this image. Most stars turn into a nebula at the end of their lives, and sometimes, like in this case, they do the same thing twice.

American Chemical Society videos on the science behind turkey pop-up timers, tryptophan and more
Does tryptophan really cause the bleary-eyed daze after a Thanksgiving meal? Why does that timer pop up from the Thanksgiving turkey at just the right moment? What causes bloating after eating? For answers to those and other questions that could spark lively dinnertime conversation next Thursday, the American Chemical Society is offering an addition to the holiday menu: two Bytesize Science videos uncovering the chemistry behind Thanksgiving, available at www.BytesizeScience.com.

Rainforest insect hears like a human
The ear of the South American rainforest katydid sits on the insect's hind legs, and it's one of the smallest of all hearing organs. But in other ways, the katydid ear is remarkably similar to the mammalian ear, researchers have discovered.
