'Metabolic Taxation' Responsible for Animal Growth Rate
In physical, as in financial growth, it's not what you make but what you keep that counts, USC marine biologists believe.Their study of genes associated with growth in oysters suggests that slow-growing animals waste energy in two ways: by making too much of some protein building blocks and then by having to dispose of the excess.Donal Manahan, director of the USC Wrigley Institute for ...

State spending $650,000 for sensors to alert U.S. 41 drivers panthers may be near
Backed by conservation groups, the Florida DOT plans to install devices on a 1.3-mile stretch of U.S. 41 west of Turner River Road to detect animals and activate warning signs to alert motorists. The $650,000 plan is an alternative to a controversial proposal to install two wildlife crossings.

Even oysters pay taxes
( University of Southern California ) Study of oyster genes associated with growth suggests that fast-growing animals have better tuned ribosomal factories for making proteins, USC marine biologists say.

Evidence Indicates Humans' Early Tree-dwelling Ancestors Were Also Bipedal
(PhysOrg.com) -- More than three million years ago, the ancestors of modern humans were still spending a considerable amount of their lives in trees, but something new was happening.

The Same Kind Of Circadian Rhythms That Govern Human Sleep Control Cell Division In Cyanobacteria
A team of researchers at MIT and the University of California at San Diego has shown how cell division in a type of bacteria known as cyanobacteria is controlled by the same kind of circadian rhythms that govern human sleep patterns. Previous studies have shown that even though cyanobacteria do not "sleep" in the same way that humans do, they cycle through active and resting periods on a 24-hour ...

Even Oysters Pay Taxes
'Metabolic taxation' accounts for part of difference between fast and slow growth of animals, according to a new theory. USC marine biologists say that a study of oyster genes associated with growth suggests that fast-growing animals have better tuned ribosomal factories for making proteins.

Evidence indicates humans' early tree-dwelling ancestors were also bipedal
Experiments by anthropologists show that fossil footprints made 3.6 million years ago are the earliest direct evidence of early hominids using the kind of efficient, upright posture and gait now seen in modern humans.

Evidence indicates humans' early tree-dwelling ancestors were also bipedal
( University of Arizona ) Experiments by University of Arizona anthropologist David Raichlen and his colleagues show that fossil footprints made 3.6 million years ago are the earliest direct evidence of early hominids using the kind of efficient, upright posture and gait now seen in modern humans.
