Astronomy & Space news

	SpaceX launches 3-D printer, other station gear A SpaceX cargo ship rocketed toward the International Space Station on Sunday, carrying the first 3-D printer for astronauts in orbit.
	MAVEN Mars spacecraft to begin orbit of Red Planet A NASA spacecraft that aims to study the upper atmosphere of Mars and reveal how its climate changed over time is poised to begin orbiting the Red Planet on Sunday.
	Internet moguls Musk, Bezos shake up US space race The space race to end America's reliance on Russia escalated this week with a multibillion dollar NASA award for SpaceX's Elon Musk and an unexpected joint venture for Blue Origin's Jeff Bezos.
	Bad weather delays SpaceX launch with 3-D printer Rainy weather has forced SpaceX to delay its latest supply run to the International Space Station.

Medicine & Health news

	New cancer drug target involving lipid chemical messengers More than half of human cancers have abnormally upregulated chemical signals related to lipid metabolism, yet how these signals are controlled during tumor formation is not fully understood.
	Scientists discover an on/off switch for aging cells (Medical Xpress)—Scientists at the Salk Institute have discovered an on-and-off "switch" in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age.
	Immune system of newborn babies is stronger than previously thought Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study led by King's College London. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense, finds the study published in the journal Nature Medicine.
	Cancer cells adapt energy needs to spread illness to other organs Want to understand why cancer cells metastasize? Think of Sparta. Ancient Greek warriors were fed a special diet that better prepared them for the demands of battle on distant fields. Cancer cells that metastasize may do the same thing according to a new study revealing previously unknown differences between cancer cells that continue to grow at the original tumor site, and those that travel to other organs.
	Ultrasound enhancement provides clarity to damaged tendons, ligaments The potential was hidden in plain sight, pretty much since the beginning of medical ultrasound. But it took an expert in earthquake waves to unearth the idea that sound waves reflected from human bodies could reveal not only their internal shape, but also their condition.
Sierra Leone faces criticism over Ebola shutdown Sierra Leone began the second day of a 72-hour nationwide shutdown aimed at containing the spread of the deadly Ebola virus on Saturday amid criticism that the action was a poorly planned publicity stunt.
	Sierra Leone reaches final day of Ebola lockdown Frustrated residents complained of food shortages in some neighborhoods of Sierra Leone's capital on Sunday as the country reached the third and final day of a sweeping, unprecedented lockdown designed to combat the deadly Ebola disease, volunteers said.
Liberia to provide 1,000 Ebola beds in overwhelmed capital Liberia announced plans Sunday for a four-fold increase in beds for Ebola patients in its overwhelmed capital Monrovia, as US troops arrived to help tackle the deadly epidemic.
Jobless and poor, Ghana's youth turn to selling blood To Ghana's legions of jobless young men, Eric Bimpong has a money-making proposition: sell your blood.
Overwhelmed west Africa ramps up Ebola response West Africa intensified its response to the deadly Ebola epidemic on Sunday, with Sierra Leone uncovering scores of dead bodies during a 72-hour shutdown and Liberia announcing hundreds of new hospital beds.
