Injured sea turtle treated at Miami Seaquarium

A threatened sea turtle is being treated for a life-threatening gash to its shell after apparently being struck by a boat in South Florida, officials said Tuesday. A Miami homeowner spotted the lethargic, injured loggerhead turtle Monday in a canal that leads into Biscayne Bay, said Florida Fish and Wildlife Conservation Commission spokesman Jorge Pino.…

Climate science making inroads

Nicholas Ogle stands at the water’s edge on Florida International University’s Biscayne Bay campus and holds what looks like a giant, rotten green bean out to the crowd of teenagers in front of him. “We don’t want any mushiness anywhere, especially at the top,” he says, and chucks the specimen to the side. Ogle, an…

Rare New Microbe Found in Two Spacecraft Clean Rooms

A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft clean rooms in Florida and South America. Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft clean rooms. Fewer microbes live there than in almost any other environment on Earth, but…

Amazon Deforestation Could Mean Droughts for Western U.S.

In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires The researchers report in…

Tricking Algae’s Biological Clock Boosts Production of Drugs, Biofuels

Tricking algae's biological clock to remain in its daytime setting can dramatically boost the amount of valuable compounds that these simple marine plants can produce when they are grown in constant light. That is the conclusion of a "proof of concept" experiment described in the Dec. 2 issue of the journal Current Biology. The study found…

Scientists Solve Major Piece in the Origin of Biological Complexity

Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce. Now researchers led by University of Minnesota College of Biological Sciences postdoctoral fellow William Ratcliff and associate professor Michael Travisano have set a big piece of that puzzle…

Did Inefficient Cellular Machinery Evolve to Fight Viruses and Jumping Genes?

It might seem obvious that humans are elegant and sophisticated beings in comparison to lowly bacteria, but when it comes to genes, a UC San Francisco scientist wants to turn conventional wisdom about human and bacterial evolution on its head. Far from being sleekly performing and fine-tuned athletes, the molecules guiding the activity of our…

Novel Genetic Patterns May Make Us Rethink Biology and Individuality

Professor of Genetics Scott Williams, PhD, of the Institute for Quantitative Biomedical Sciences (iQBS) at Dartmouth's Geisel School of Medicine, has made two novel discoveries: first, a person can have several DNA mutations in parts of their body, with their original DNA in the rest -- resulting in several different genotypes in one individual --…

New Challenges in the Fast Changing Landscape of Bioinformatics

The world of DNA sequencing and bioinformatics has evolved at a staggering pace. In 2009, the biggest problem for researchers was creating an efficient solution for sequencing DNA. At that time, sequencing cost of $100,000 for a single human and took 30 days of chemical processing to produce the raw sequencing output. In four years,…
