Ancient Mayan deforestation had long-term effects on watershed carbon cycles

Researchers: Mark Brenner, brenner@ufl.edu, 352-392-7226, Jason Curtis, curtisj@ufl.edu PIO: Rachel Wayne, 352-872-2620 The lowlands of Mexico and Guatemala experienced widespread deforestation by the Maya beginning about 4,000 years ago. The region has never fully recovered. Ancient Maya environmental impact provides a case study for the long-term effects of deforestation, and according to a new Nature […]

The Starving Snakes of Seahorse Key

Mysteriously vanished waterbirds. Cannibalistic snakes. An island with no freshwater except for rainfall. It may sound like a Crichton novel or SyFy original movie, but it’s the reality of Seahorse Key, part of the Gulf Coast Cedar Keys that University of Florida biologists have been researching since the 1930s, when the renowned late zoologist Archie Carr first began studying the unusually large cottonmouth population there.

The artist's rendering (left) of GRB 050709 depicts a gamma-ray burst that was discovered on 9 July, 2005 by NASA's High-Energy Transient Explorer. The burst radiated an enormous amount of energy in gamma-rays for half a second, then faded away. Three days later, Chandra's detection of the X-ray afterglow (inset) established its position with high accuracy. A Hubble Space Telescope image showed that the burst occurred in the outskirts of a spiral galaxy. This location is outside the star-forming regions of the galaxy and evidence that the burst was not produced by the explosion of an extremely massive star. The most likely explanation for the burst is that it was produced by a collision of two neutron stars, or a neutron star and a black hole.

Solving Cosmic Puzzles

Neutron stars are dead stars collapsed into the densest form of matter known to humans, with a teaspoon of neutron star matter weighing a billion tons, and their collision creates a swath of galactic debris. Decades ago, stargazing scientists formed plans to detect signals from this debris. Now, in the new era of aptly named “multi-messenger astronomy,” two international projects have achieved this goal: On August 17 of this year, the Laser Interferometer Gravitational-Wave Observatory (LIGO)’s two U.S.-based interferometers and the Virgo Collaboration’s Italy-based interferometer detected for the first time gravitational waves — ripples in space-time traveling at the speed of light — from the collision and subsequent merger of two neutron stars. The detection occurred just three days after yet another “chirp” from colliding black holes.

A Route to Recovery

UF psychologist Lori Knackstedt studies an antibiotic that may cure cocaine addiction. Lori Knackstedt, professor of psychology, is seven years deep into research that’s yielded some surprising results: in cocaine-addicted rats, an antibiotic reduces their drug-seeking behavior and may prevent relapse. The drug Ceftriaxone appears to increase reuptake of glutamate, a neurotransmitter that regulates dopamine, […]
