Astronomy & Space news

	Lunar explorers will walk at higher speeds than thought Anyone who has seen the movies of Neil Armstrong's first bounding steps on the moon couldn't fail to be intrigued by his unusual walking style. But, contrary to popular belief, the astronaut's peculiar walk was not the result of low gravity. Wyle Science, Engineering and Technology scientist John De Witt explains that the early space suits were not designed for walking, so the astronauts adapted their movements to the restrictions of the suit.
	NASA Extreme Environment Mission Operations (NEEMO) prepare astronauts ESA astronaut Andreas Mogensen is looking forward to flying to the International Space Station next year but until yesterday he was underwater trying out a handy new device he will use in space.
	What is life? It's a tricky, often confusing question What is life? This is a question that is often asked and typically confused.
	The Great Debate over whether the universe is small or large The visible universe is vast. It is 93 billion light years across, and contains more than 100 billion galaxies. The average galaxy contains about 100 billion stars, and untold numbers of planets. Yet a century ago there was serious doubt among many astronomers that the universe was much more than 100,000 light years across. Arguments about whether the universe was small or large became known as the Great Debate.
	The latest observations of interstellar particles With all the news about Voyager 1 leaving the heliosphere and entering interstellar space you might think that the probe is the first spacecraft to detect interstellar particles. That isn't entirely true, and the latest observations of interstellar particles has found some very interesting results.
	Very Long Baseline Array takes radio image of Voyager 1 The image above is a radio image of Voyager 1. It was taken from the Very Long Baseline Array, which is a collection of 10 radio telescopes scattered from Hawaii to the Virgin Islands. It captures the faint radio signal of the distant probe. That pale blue dot is the most distant object made by humans.
Spaceship designer who helped send Gagarin into orbit dies at 92 A spaceship designer who worked on Yury Gagarin's Vostok spaceship and was the last to shake his hand before liftoff, Oleg Ivanovsky, died on Thursday at 92, the Russian space agency said.
	Everything in moderation: Micro-8 to study regulating pathogens in space Our bodies are breeding grounds for microbes—don't worry, it's a good thing! As scientists have been telling us for years, not all microbes are bad. Many active enzymes and bacteria are merely benign, and, in moderation, are beneficial to humans as an important part of our digestive system or can help regulate our immune system.
	Miranda: An icy moon deformed by tidal heating Miranda, a small, icy moon of Uranus, is one of the most visually striking and enigmatic bodies in the solar system. Despite its relatively small size, Miranda appears to have experienced an episode of intense resurfacing that resulted in the formation of at least three remarkable and unique surface features—polygonal-shaped regions called coronae.
	Buzzing with activity: Fruit flies orbit Earth for science If the International Space Station ever starts a "frequent flyers" program, fruit flies surely would be eligible for platinum status. Recently the orbiting laboratory has hosted increasing numbers of fruit fly research studies. One fruit fly investigation returned from the space station in April, and another is scheduled launch to the station Sept. 20. A third experiment is planned to launch in December.
	France raises heat on decision for next Ariane rocket France's space agency on Thursday unveiled a revised proposal for an Ariane rocket ahead of a tough decision on launchers by the European Space Agency (ESA).

As their prize, the scientists will see the International Space Station crew perform experiments on the space station. The project involves crystallizing two proteins of the hepatitis C virus under microgravity conditions. The shuttle bringing these proteins to the International Space Station is scheduled to lift off from Cape Canaveral on Sept. 20.

Medicine & Health news

	'Dimmer switch' for mood disorders discovered Researchers at University of California, San Diego School of Medicine have identified a control mechanism for an area of the brain that processes sensory and emotive information that humans experience as "disappointment."
	Ultrafast spikes carry supra-kilohertz signals in the cerebellum (Medical Xpress)—One of the challenges in high energy physics is to understand the origin of cosmic rays. The problem is that although these rays continue to be observed at ever higher energies, there is currently no known physical mechanism to fully explain how they attain that energy. The same issue is found in neuroscience. Researchers continue to find neurons that fire spikes at higher and higher rates (>1500 hz) but the models that traditionally have been used to describe them start to break down far below that.
	Wild berry extract may strengthen effectiveness of pancreatic cancer drug A wild berry native to North America may strengthen the effectiveness of a chemotherapy drug commonly used to treat pancreatic cancer, reveals research published online in the Journal of Clinical Pathology.

Researchers from the Brain Mind Institute (BMI) at EPFL have just highlighted a fundamental synaptic mechanism that explains the relationship between chronic stress and the loss of social skills and cognitive impairment. When triggered by stress, an enzyme attacks a synaptic regulatory molecule in the brain. This was revealed by a work published in Nature Communications.
Gel-like padding could help cells survive injection, heal spinal cord injuries (Medical Xpress)—A team of Bio-X scientists is developing a gel to help protect cells from the trauma of being injected into an injury site. The work could help speed cell-based therapies for spinal cord injuries and other types of damage.
	Scientists uncover the neural basis of confidence in the rat brain Life is a series of decisions, ranging from the mundane to the monumental. And each decision is a gamble, carrying with it the chance to second-guess. Did I make the right turn at that light? Did I choose the right college? Was this the right job for me?
	Single dose of antidepressant changes the brain A single dose of antidepressant is enough to produce dramatic changes in the functional architecture of the human brain. Brain scans taken of people before and after an acute dose of a commonly prescribed SSRI (serotonin reuptake inhibitor) reveal changes in connectivity within three hours, say researchers who report their observations in the Cell Press journal Current Biology on September 18.
New molecule allows for increase in stem cell transplants Investigators from the Institute for Research in Immunology and Cancer (IRIC) at the Université de Montréal have just published, in the prestigious magazine Science, the announcement of the discovery of a new molecule, the first of its kind, which allows for the multiplication of stem cells in a unit of cord blood. Umbilical cord stem cells are used for transplants aimed at curing a number of blood-related diseases, including leukemia, myeloma and lymphoma. For many patients this therapy comprises a treatment of last resort.
	A new way to prevent the spread of devastating diseases For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases.
	New technique uses a genetic tool and light to view and map neuronal circuits For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain's circuitry in action—from the first moment a neuron fires to the resulting behavior in a whole organism. To get this complete picture, neuroscientists are working to develop a range of new tools to study the brain. Researchers at Caltech have developed one such tool that provides a new way of mapping neural networks in a living organism.

Study discovers means to free immune system to destroy cancer Research led by Paulo Rodriguez, PhD, an assistant research professor of Microbiology, Immunology & Parasitology at LSU Health New Orleans' Stanley S. Scott Cancer Center, has identified the crucial role an inflammatory protein known as Chop plays in the body's ability to fight cancer. Results demonstrate, for the first time, that Chop regulates the activity and accumulation of cells that suppress the body's immune response against tumors. The LSU Health New Orleans research team showed that when they removed Chop, the T-cells of the immune system mounted an effective attack on the cancer cells. These findings reveal Chop as a target for the development of new immunotherapies to treat cancer. The research is described in a paper published online September 18, 2014, in Immunity, a Cell Press journal.
