Killing for DNA: A predatory device in the cholera bacterium
Vibrio cholerae uses a predatory killing device to compete with surrounding bacteria and steal their DNA. This molecular killing device a spring-loaded spear that is constantly shooting out. This weapon is called the "type VI secretion system" (T6SS) and is known to exist in many types of bacteria. When V. cholerae comes close to other bacteria, the spear punches a hole into them, leaving them to die and release their genetic material, which the predator pulls into itself.

New Virus Unlike Anything Ever Seen
The CDC says it’s never seen anything like it before, and it’s already claimed a life in the U.S.
A new virus thought to be carried by ticks or other insects has been discovered following the death of a southeast Kansas resident during the summer, public health officials said Monday.
The new virus is called Bourbon virus, after Bourbon County, home of the patient who died. The Kansas Department of Health and Environment said the patient's symptoms, including fever and fatigue, were similar to symptoms from other tick-borne diseases.

Lens-free microscope can detect cancer at the cellular level
UCLA researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes.
The device works by using a laser or light-emitting-diode to illuminate a tissue or blood sample that has been placed on a slide and inserted into the device. A sensor array on a microchip — the same type of chip that is used in digital cameras, including cellphone cameras — captures and records the pattern of shadows created by the sample.
