Scientists examining documents dating back 3,500 years say they have found proof that the origins of modern medicine lie in ancient Egypt and not with Hippocrates and the Greeks.
The research team from the KNH Centre for Biomedical Egyptology at The University of Manchester discovered the evidence in medical papyri written in 1,500BC- 1,000 years before Hippocrates was born.
"Classical scholars have always considered the ancient Greeks, particularly Hippocrates, as being the fathers of medicine but our findings suggest that the ancient Egyptians were practising a credible form of pharmacy and medicine much earlier," said Dr Jackie Campbell.
"When we compared the ancient remedies against modern pharmaceutical protocols and standards, we found the prescriptions in the ancient documents not only compared with pharmaceutical preparations of today but that many of the remedies had therapeutic merit."
The medical documents, which were first discovered in the mid-19th century, showed that ancient Egyptian physicians treated wounds with honey, resins and metals known to be antimicrobial.
The team also discovered prescriptions for laxatives of castor oil and colocynth and bulk laxatives of figs and bran. Other references show that colic was treated with hyoscyamus, which is still used today, and that cumin and coriander were used as intestinal carminatives.

The genetic survey, produced by a collaborative team led by scholars at Cambridge and Anglia Ruskin Universities, shows that Australia's aboriginal population sprang from the same tiny group of colonists, along with their New Guinean neighbours.
Something weird hung high in the mid-morning sky earlier this week like a vision from Superman's home planet Krypton - a red sun.
OK, maybe not all that weird; after all, even the morning drive-time radio guys pointed out that smoke from Southwest Florida's wildfires had made the sun go red.

Some astronomers would be delighted if a super-bright supernova blast like the one reported this week were to occur in our own galaxy. One says it could be "the best star-show in the history of modern civilization." But if the blast was pointed right at us from close quarters? Well, that would be bad.

A mysterious dip in gravity over Canada has been a weighty topic for some scientists. Now satellite data reveal a thick ice sheet that once cloaked the region partially resolves this so-called gravitational anomaly.
Vehicles may crowd the asphalt of downtown Los Angeles freeways above ground, but below ground hundreds of newly discovered bacteria thrive by munching on heavy oil and natural asphalt.
Trapped in the Rancho La Brea tar pits 28,000 years ago, the bacteria are equipped with special enzymes that can break down petroleum, environmental scientists at the University of California, Riverside report in a recent issue of Applied and Environmental Microbiology.

This was quite a burst!
The main emission of gamma rays lasted for about 50 seconds, and had about *20* bright peaks during the first 20 seconds. After that it faded, but emission was seen for about 800 second total, making this one of the longest bursts ever seen. The Japanese satellite Suzaku also detected the burst, as did the Konus-WIND experiment.

There seems to be something new under the sun -- in the sky, specifically -- that could complicate scientists' efforts to get a fix on how much the world will warm in the future. Greenhouse gases are not the only things in the air that influence the temperature of our atmosphere. Clouds and small airborne particles called aerosols also play an important and complicated role. And now a new ingredient has been discovered: an extensive and previously unseen "twilight zone" of particles that represents a gradual transition from cloud droplets to dry particles.

| What appears as clear sky around a cloud as seen from the ground through a digital camera (left) actually has a twilight zone of light-reflecting particles around it (right). To see this, the blue light from the atmosphere in the original image is first subtracted (middle). The twilight zone is revealed after the darker parts of the image are enhanced (right). |
A new study by NASA scientists suggests that greenhouse-gas warming may raise average summer temperatures in the eastern United States nearly 10 degrees Fahrenheit by the 2080s.
"There is the potential for extremely hot summertime temperatures in the future, especially during summers with less-than-average frequent rainfall," said lead author Barry Lynn of NASA's Goddard Institute for Space Studies and Columbia University, New York.
