Despite having the same name, the diseases that killed Apple co-founder Steve Jobs and 2011 Nobel laureate Ralph Steinman are different kinds of cancer. Researchers are looking for new ways to diagnose and treat both
Update Sept. 11, 2015: ZomBee Watch, a citizen science project, reported on September 1, 2015 that one of its participants, Joseph Naughton, discovered and captured a honey bee parasitized by the zombie fly Apocephalus borealis on his porch in New York.
LONGMONT, Colo.—Three days of soaking rain in Colorado have unleashed damaging floods in and around Denver, Boulder and Colorado Springs and isolated some towns in the foothills of the Rockies.
New DNA recovery and sequencing technology is at last allowing scientists to assemble entire genomes of ancient scourges—and elusive modern ones
Like a starfish, an octopus can regrow lost arms. Unlike a starfish, a severed octopus arm does not regrow another octopus. But the biological secrets inside their arm regeneration feat do hold the promise of learning more about how we might better regenerate our own diseased or lost tissue.
The eight wily arms of an octopus can help the animal catch dinner, open a jar and even complete a convincing disguise. But these arms are not entirely under the control of the octopus’s brain.
Octopuses offer an extreme engineering challenge: They are almost infinitely flexible, entirely soft-bodied and incredibly intelligent. Are we vertebrate humans ever going to be able to build anything as deformable and complex as a real octopus?

And new research shows how genetic alterations in this odd-colored blood have helped the octopus colonize the world's wide oceans—from the deep, freezing Antarctic to the warm equatorial tropics.The iron-based protein (hemoglobin) that carries oxygen in the blood for us red-blooded vertebrates becomes ineffective when faced with low-oxygen levels.
