Scientists Launch Worldwide Search for Lost Species [Slide Show] A few years ago at a bar in Reno, graduate student John Zablocki was talking about his research on the rediscovery of lost species—those presumed to have gone extinct only to turn up again alive and well—when a stranger chimed in.

“What about the Lord Howe Island stick insect?” He suggested, recalling the widely reported 2001 rediscovery of that species on an island in Australia. Recalling the celebrated line from the 1993 movie Jurassic Park, the stranger added: “Life, uh, finds a way.” This is the tantalizing thing—when a species thought to be lost comes back, in effect, from the dead, Zablocki says. It hints at rebirth in an era otherwise dominated by headlines about climate change and mass extinction. But finding lost species does not take a miracle, according to Global Wildlife Conservation (GWC), a small Texas-based nonprofit.

The plan is to work with international partners to put scientists in the field, with an initial fund-raising goal of $500,000.

Note: Some of the information here about the Mona Lisa was previously described in: Martinez-Conde, S. and Macknik, S.L. (2010, May 1st). What's in a Face? Scientific American, 3-4. Perhaps The Mona Lisa is the most famous painting in history because her enchanting smile is art’s most enigmatic mystery. By looking directly at Mona Lisa's lips, we notice that her smile is understated, almost nonexistent. In the visual field, the center and the periphery possess a different initial effect on perception. Viruses Gettin' Viruses. Psychology's Ongoing Credibility Crisis. It’s a tough time to be a young psychologist.

Psychology's Ongoing Credibility Crisis

This thought keeps occurring to me as we search for a new psychology professor at my school, Stevens Institute of Technology. When I meet candidates, I have to ask about their field’s replication—and credibility—crisis. I feel as though I’m pressing them on some sordid personal matter, like whether alcoholism runs in their families, but the topic is unavoidable. Last summer, a group called the “Open Science Collaboration” reported in Science that it had replicated fewer than half of 100 studies published in major psychology journals.

The New York Times declared in a front-page story that the report “confirmed the worst fears of scientists who have long worried that [psychology] needed a strong correction. The crisis keeps generating headlines. The exchange, Benedict Carey notes in the Times, “is likely to feed an already lively debate about how best to conduct and evaluate so-called replication projects of studies.” It gets worse. 3 Cosmic Mysteries. Despite remarkable accomplishments (and despite any claims to the contrary), we are in many, many respects still profoundly ignorant about the nature of the universe and its contents.

3 Cosmic Mysteries

That might seem depressing, but I think it's wonderfully exciting - there are so many things for the human intellect to study and attempt to understand, so much fun to be had and so much awe to explore! For a little northern-hemisphere summer stimulation I've picked a triplet of puzzles spread across this and two other posts.

These certainly aren't the only big conundrums for science - but they're good fodder for sun-dazed pondering. #3: Origins of Consciousness & Intelligence In post #2 in this short series I talked about the origins of life as a cosmic mystery. Look up consciousness on Wikipedia and you'll get a definition that starts with '...the state or quality of awareness..' Don't you just hate it when that happens. Except, we really don't have any final answers yet. That's mind-blowing. Una almeja vivió 507 años y tú también puedes. El animal más viejo del mundo vivió 507 años.

Fue una almeja de Islandia que había nacido en 1499, antes que Miguel de Cervantes. Murió en 2006 tras ser recolectada por unos científicos. Un año después, en 2007, apareció en Alaska una ballena boreal con un arpón clavado desde el siglo XIX, sugiriendo que este mamífero puede vivir dos siglos. Y las mariposas monarca, que normalmente solo viven unas pocas semanas, producen una vez al año una generación Matusalén que alcanza los seis meses de vida para poder migrar desde Canadá a los templados bosques de México.

Científicos finalmente descubrieron la clave de la estructura del cáncer. Ha sido una espera larga, pero finalmente científicos en los EE.UU., han descubierto la estructura atómica de PRC2, un complejo de enzimas que juega un papel crucial en el desarrollo de varios tipos de cáncer.

Al parecer, ésta enzima desencadena las mutaciones en el gen PRC2, que está relacionado con el desarrollo de linfoma, leucemia y tumores cerebrales, además de una serie de enfermedades congénitas que afectan el crecimiento de una persona. "Nuestros hallazgos nos llevan un paso más cerca de comprender la química de cómo PRC2 funciona en las células normales y cómo las mutaciones en el gen causan la enfermedad", aseguró Xin Liu, de la Universidad de Texas.
