Paleontology. Tiny, feathered dino is most birdlike yet.

Chinese paleontologists studying the fossil known as Microraptor describe it as both the smallest and the most birdlike dinosaur yet discovered. In this week's issue of Nature, they say the crow-sized, feathered creature--whose fossilized tail once formed part of a now-discredited "missing link" between birds and dinosaurs known as Archaeoraptor--belongs to the dromaeosaurs, dinosaurs that many paleontologists consider the closest dinosaurian relatives of birds.

Society of Vertebrate Paleontology. Fossils come to life in Mexico.

New insights into ancient life came by land and sea at the 60th annual meeting of the Society of Vertebrate Paleontology, held here from 25 to 28 October. Stunningly preserved fossils from Mongolia gave contrasting views of dinosaur family life, while biomechanical models clocked the swimming speed of cruising ichthyosaurs.

5TH International Ancient DNA Conference. Divining diet and disease from DNA.

Some 110 scientists from a range of disciplines gathered in the overcast British midlands for the 5th International Ancient DNA Conference, held here from 12 to 14 July. Among the attractions were new insights into the diets of early Americans gleaned from ancient human coprolites and intriguing reports of nuclear DNA and ancient viral sequences extracted from mammoth bones.

What makes a police officer a victim?

In the United States, about 150 police officers die every year in the line of duty, and government figures suggest that some 350 suspected criminals are justifiably killed in confrontations with police. Seeking lessons behind these gruesome statistics and other disturbing trends in violent behavior nationwide (see main text) are researchers at the Federal Bureau of Investigation.

Paleontology. Feathers, or flight of fancy?

On page 2202, researchers describe the 220-million-year-old Longisquama insignis, a squat, mouse-sized reptile with at least six vanelike appendages up to 12 centimeters long sprouting from its spine. The authors argue that the appendages are feathers much like those of modern birds; outside the paper, they have touted the fossil as "an ideal bird ancestor." That conclusion has infuriated paleontologists--not just because it challenges the prevalent theory that birds evolved from theropod dinosaurs, but because they say it does so in an unscientific way.

Paleontology. Learning to dissect dinosaurs--digitally.

In the past 2 decades, as the resolution of computed tomography (CT) scans has grown sharper, paleontologists have increasingly trained the technique on long-dead animals, gaining an inside view of rich anatomical detail, including everything from bony canals that once held nerves to the internal networks of dinosaur noses. The technique doesn't work on all samples, and the images still require a trained eye to interpret. But CT scanning has contributed to a number of high-profile discoveries.
