Captioned Image Spotlight: Colorful Impact

Some regions of Mars are not very colorful, but we can be surprised by local features. This image of an impact crater in the south Syrtis Major region was acquired as a “ride-along” with a CRISM observation, which targeted this location because that instrument’s team expected a distinct composition.

Our enhanced image reveals colors ranging from red to green to blue. These are infra-red shifted colors (infrared-red-blue) so it’s different than what we would see with our eyes.

2,400-year-old Greek tombs found in Bulgaria’s Sozopol

Bulgarian and French archaeologists have discovered an impressive tomb from the second half of the 4th and the beginning of the 3rd century BC during the course of rescue excavations on the northern slope of the Budjaka Hill.

In the embankment, with an area of ​​about 180 square metres, they discovered the largest family tomb known since the studies of the necropolis of Apollonia. It has a rectangular shape, 6.2 x 8 metres.
The outer walls are made of massive well-formed blocks without cementing. It revealed the skeleton remains of two women and one man, probably members of a rich Apollonian family.

Two of the graves are of the cist type in which the rectangular grave chamber and the coating are made of solid stone blocks. In the central grave there is a scattered burial inventory.

The walls of the burial chamber are coloured in red. The analysis of the findings leads to the scientific hypothesis that the grave is for a woman.

A similar tomb was found in the southeast corner of the necropolis. In it are laid the remains of a male with richer and varied tomb gifts – two bronze skyphoi and pottery, including oinochoe and lekythoi.

The remains of a woman were laid on the stone cover of the second grave, which was then covered with a mound.

Preliminary analysis indicates that the tomb is from the time when the Black Sea polis and surrounding Thracian dynasties were conquered by the Macedonian Empire of Alexander the Great and his successor Lysimachos.

Treatment in Sight This large green-coloured mass visible…

Treatment in Sight

This large green-coloured mass visible inside a patient’s eye is a uveal melanoma. Arising from the pigmented cells of the eye, such as those in the iris, uveal melanomas are rare but often fatal, killing approximately half of the patients in whom they develop. Such tumours may be treated with surgical removal of the eye or radiation therapy prior to metastasis, but once the cancer has spread, effective treatments are limited. But now scientists have discovered a natural plant compound, derived from a member of the primrose family, that inhibits the growth of uveal melanoma cells in culture. The flower substance binds tightly to an oncogenic – cancer driving – protein in the melanoma cells preventing its activity and, in so doing, either kills the cells or turns them back into apparently normal uveal cells. The next step is to test this primrose compound in animal models of uveal cancer.
