Q: The Bilateria or bilaterians, or triploblasts, are animals with bilateral symmetry, i.e., they have a head ("anterior") and a tail ("posterior") as well as a back ("dorsal") and a belly ("ventral"); therefore they also have a left side and a right side. In contrast, radially symmetrical animals like jellyfish have a topside and a downside, but no identifiable front or back.

The bilateria are a major group of animals, including the majority of phyla but not sponges, cnidarians, placozoans and ctenophores. For the most part, bilateral embryos are triploblastic, having three germ layers: endoderm, mesoderm, and ectoderm. Nearly all are bilaterally symmetrical, or approximately so; the most notable exception is the echinoderms, which achieve near-radial symmetry as adults, but are bilaterally symmetrical as larvae.

Except for a few phyla (i.e. flatworms and gnathostomulids), bilaterians have complete digestive tracts with a separate mouth and anus. Some bilaterians lack body cavities (acoelomates, i.e. Platyhelminthes, Gastrotricha and Gnathostomulida), while others display primary body cavities (deriving from the blastocoel, as pseudocoel) or secondary cavities (that appear "de novo", for example the coelom).

The hypothetical most recent common ancestor of all bilateria is termed the "Urbilaterian". The nature of the first bilaterian is a matter of debate. One side suggests that acoelomates gave rise to the other groups (planuloid-aceloid hypothesis by Graff, Metchnikoff, Hyman, or ), while the other poses that the first bilaterian was a coelomate organism and the main acoelomate phyla (flatworms and gastrotrichs) have lost body cavities secondarily (the Archicoelomata hypothesis and its variations such as the Gastrea by Haeckel or Sedgwick, the Bilaterosgastrea by Gosta Jagersten , or the Trochaea by Nielsen).

Q: (CNN) -- Two Kenyan aid workers who had been held by the al Qaeda-linked militant group Al-Shabaab since 2011 have been rescued near Somalia's border with Kenya, the African Union Mission in Somalia said Friday.

The rescue was carried out on the outskirts of Dhobley town in Somalia by peacekeepers for the mission, known by the acronym AMISOM, who were working with Somali forces, AMISOM said in a news release.

One of the rescued, James Kiarie Gichoi, was working for Care International when he was kidnapped near the Dadaab refugee camp in Kenya.

The other, Daniel Njuguna Wanyoike, was working as a driver's helper for a company contracted by the aid group Medecins Sans Frontieres when he was kidnapped in Afmadow, a nearby town in Somalia.

Both men were receiving treatment Friday at an AMISOM medical facility in nearby Dhobley, Somalia, and were expected to be repatriated to Nairobi, Kenya.

AMISOM forces working with the Somali National Army have mounted an offensive that has liberated 10 towns that were among Al-Shabaab's strongholds, said AMISOM, the African Union peacekeeping mission in Somalia.

Al-Shabaab, designated a foreign terrorist organization by the United States, has a relationship with al Qaeda that goes back several years. In 2012, the two groups effectively merged, said CNN national security analyst Peter Bergen.

Al-Shabaab hopes to turn Somalia into a fundamentalist Islamic state, but has launched attacks in other countries as well.

In 2010, Al-Shabaab claimed responsibility for two suicide bombings in Kampala, Uganda, amid crowds of soccer fans watching televised screenings of the World Cup final. The bombings left 74 people dead.
