Telescopes give shape to furious black hole winds

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA's (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions—a phenomenon that had been suspected, but difficult to prove until now.

Does dark matter cause mass extinctions and geologic upheavals?

Research by New York University Biology Professor Michael Rampino concludes that Earth's infrequent but predictable path around and through our Galaxy's disc may have a direct and significant effect on geological and biological phenomena occurring on Earth. In a new paper in Monthly Notices of the Royal Astronomical Society, he concludes that movement through dark matter may perturb the orbits of comets and lead to additional heating in the Earth's core, both of which could be connected with mass extinction events.

Disintegrating rocky exoplanet could unlock secrets to how our solar system was formed

Exciting new research by astronomers at The Open University (OU) and the Universities of Warwick and Sheffield has opened up the chance to find out what distant planets are made of. The team of astronomers have made observations which can help reveal the chemical makeup of a small rocky world orbiting a distant star about 1500 light years away from Earth, increasing our understanding of how planets, including ours, were formed.

Mars hills hide icy past

A complex network of isolated hills, ridges and small basins spanning 1400 km on Mars is thought to hide large quantities of water-ice.

A new view of the solar system: Astrophysical jets driven by the sun

As the sun skims through the galaxy, it flings out charged particles in a stream of plasma called the solar wind, and the solar wind creates a bubble extending far outside the solar system known as the heliosphere. For decades, scientists have visualized the heliosphere as shaped like a comet, with a very long tail extending thousands of times as far as the distance from the Earth to the sun.

Hubble gets best view of a circumstellar debris disk distorted by a planet

Astronomers have used NASA's Hubble Space Telescope to take the most detailed picture to date of a large, edge-on, gas-and-dust disk encircling the 20-million-year-old star Beta Pictoris.

MAVEN spacecraft completes first deep dip campaign

NASA's Mars Atmosphere and Volatile Evolution has completed the first of five deep-dip maneuvers designed to gather measurements closer to the lower end of the Martian upper atmosphere.

The origin of the magnetic field covering the Sun has been discovered

The magnetic field that covers the sun and determines its behavior –the eleven year cycles no less than such conspicuous phenomena as solar spots and solar storms– also has another side to it: a magnetic web that covers the entire surface of the sun at rest and whose net magnetic flow is greater than that of the active areas. A study led by the Institute of Astrophysics of Andalusia (IAA-CSIC) has revealed where the flow that feeds this web comes from.

Why can't we design the perfect spacesuit?

So far, every spacesuit humans have utilized has been designed with a specific mission and purpose in mind. As of yet, there's been no universal or "perfect" spacesuit that would fit every need. For example, the US ACES "pumpkin" suits and the Russian Sokol are only for launch and reentry and can't be used for spacewalks. And the Apollo A7L suits were designed with hard soled boots for astronauts to walk on the Moon, while the current NASA EMU and the Russian Orlan are designed for use in space, but with soft soled booties so as not to damage the exterior of the space station.

What is sugar's role in child hyperactivity?

For years, parents have insisted that giving kids a big dose of sugar can amp them up, but the science failed to confirm their instincts. Now, with the rising awareness of sugar's role in our diets and health, scientists are once again asking whether sugar could play a role in the growing number of new ADHD cases in American kids. It still isn't entirely clear on whether added sugar is linked to hyperactivity or clinically diagnosed ADHD. But in some areas, the evidence is building. Here's what we do and don't know about ADHD, sugar and kids.

Study provides evidence for new approaches to prostate cancer

Monitoring prostate cancer (PC) by active surveillance (AS), with the expectation to initiate treatment if the cancer progresses, is a preferred initial option for men with low-risk PC and a life expectancy of at least 10 years. According to the results of a new study conducted at Brigham and Women's Hospital (BWH), there is evidence to also support AS as an initial approach for men with favorable intermediate-risk of PC (men with no evidence of the cancer spreading beyond the prostate, a Gleason score of 3+4 or less and PSA, prostate-specific antigen, under 20). These findings are published online by JAMA Oncology.

Mitochondria adopt a crosswise pathway for decoding their genome

Mitochondria, true energy power plants of cells, are able to release the energy contained in food by means of the oxygen which we inhale. These intracellular organelles possess their own DNA, and proteins derived from these genetic instructions are produced according to a specific process, which is not well known. Misregulation of this process can cause mitochondrial genetic diseases in humans.

New test to predict the effectiveness of cancer vaccines

Cancer vaccines are designed to turn the body's own immune system specifically against tumor cells. Particularly promising are vaccines that are directed against so-called neoantigens: These are proteins that have undergone a genetic mutation in tumor cells and, therefore, differ from their counterparts in healthy cells. The tiny alteration - sometimes only a single protein building block has been changed - gives the protein on the tumor cell surface novel immunological characteristics that can be recognized as "foreign" by the immune system's T cells. Therapeutic vaccines using a short protein fragment, or peptide, specifically containing the mutated site can then direct immune cells specifically to the tumor.

HIV vaccine trial launches in South Africa

A clinical trial called HVTN 100 has been launched in South Africa to study an investigational HIV vaccine regimen for safety and the immune responses it generates in study participants. This experimental vaccine regimen is based on the one tested in the U.S. Military HIV Research Program-led RV144 clinical trial in Thailand—the first study to demonstrate that a vaccine can protect people from HIV infection. The HVTN 100 vaccine regimen was designed to provide greater protection than the RV144 regimen and has been adapted to the HIV subtype that predominates in southern Africa. The results of the HVTN 100 trial, expected in two years, will help determine whether or not this vaccine regimen will be tested for efficacy in a large future study in South Africa.
