+ - Mangalyaan's main engine test fired for 4 seconds.

Submitted by William Robinson
William Robinson (875390) writes "Before the spacecraft is scheduled to enter Mars orbit, Indian Space Research Organisation (Isro) scientists reignited the Mars Orbiter Mission spacecraft's main engine for four seconds as a trial. The liquid apogee motor (LAM) engine has been idle for about 300 days since the spacecraft left the Earth's orbit on a Martian trajectory on December 1, 2013. The short-duration test was to ensure that the engine is in good shape for the 24-minute crucial manoeuvre on Wednesday."

+ - Mangalyaan Gets Ready to Enter MARS Orbit

Submitted by William Robinson
William Robinson (875390) writes "India's Mars Orbiter Mission, known as Mangalyaan is now at a distance of just nine million kilometres from the red planet, and is scheduled to enter the orbit of Mars at 7.30 am on September 24. Mangalyaan was launched on 5th November 2013 by ISRO, presently busy planning to reduce the speed of the spacecraft through the process of firing the LAM engine and bring it to 1.6 km/sec, before it is captured by the planet's gravity."

+ - Snipping HIV-1 Out From Human Cells Achieved

Submitted by William Robinson
William Robinson (875390) writes "Scientists from Temple University School of Medicine have achieved a way to snip out the integrated HIV-1 genes for the very first time. They created molecular tools to delete the HIV-1 proviral DNA. When deployed, a combination of a DNA-snipping enzyme called a nuclease and a targeting strand of RNA called a guide RNA (gRNA) hunt down the viral genome and excise the HIV-1 DNA. From there, the cell's gene repair machinery takes over, soldering the loose ends of the genome back together – resulting in virus-free cells."

+ - Hunt for Gravitational Waves Begin as Black Hole Trio Discovered.

Submitted by William Robinson
William Robinson (875390) writes "Astronomers from Max Planck Institute for Radio Astronomy in Bonn, Germany, have discovered three closely orbiting supermassive black holes in a galaxy more than 4 billion light-years away. This is the tightest trio of black holes known to date. Researchers say the discovery will help astronomers hunt gravitational waves, the ripples in the curvature of spacetime that propagate as a wave, travelling away from the source."

Simple solution is to patch it although it might be harder on some devices.


I do welcome these kind of reports, because they will motivate procrastinating managers. I know managers having big 'change resistance', with simple arguments like "Does it affect us?". These kind of report does tell them why it is much better to act now.

+ - NASA Recreates Space Dust on Earth

Submitted by William Robinson
William Robinson (875390) writes "A team of NASA scientists has successfully replicated the process of formation of interstellar dust occurring in the atmosphere of a dying star in a specialized facility called the Cosmic Simulation Chamber (COSmiC). Scientists believe that dust grains are the building blocks of universe, enveloping dying stars and then getting eventually ejected into "interstellar medium lead" to be part of the formation of planet. During the COSmiC experiments, they could simulate gas-phase with high radiation environment by using cold argon gas filled with hydrocarbons sprayed into a vacuum, similar to the cosmic space that has average temperatures of less than negative 270 degrees Fahrenheit or about 100 degrees in Kelvin. The researchers formed and detected nanoparticles on the order of 10nm size grains varying from 100-500 nanometers and combined grains up to 1.5 micrometers in diameter"

+ - Columbus ship "Santa Maria" has been found near Haiti after 500 Years

Submitted by rtoz
rtoz (2530056) writes "The British Newspaper The Independent has reported that a team led by underwater archaeological explorer Barry Clifford found the wreck of the Christopher Columbus' flagship, the Santa Maria which sank in 1492.

"All the geographical, underwater topography and archaeological evidence strongly suggests that this wreck is Columbus’ famous flagship, the Santa Maria," said Barry Clifford.

Santa María was the largest of the three ships used by Christopher Columbus in his first voyage.

The Santa Maria was built at some stage in the second half of the 15 century in northern Spain’s Basque Country. In 1492, Columbus hired the ship and sailed in it from southern Spain’s Atlantic. After 37 days, Columbus reached the Bahamas. But after few weeks Santa Maria drifted at night onto a reef off the northern coast of Haiti and had to be abandoned."

+ - A Star Cluster Thrown Out Of Galaxy At Hypervelocity Discovered

Submitted by William Robinson
William Robinson (875390) writes "According to these reports, A globular cluster of several thousand stars, compressed into a space just a few dozen light years apart, is thrown out of galaxy M87. The cluster, named as HVGC-1, is traveling at a rate of 2 million miles per hour. The discovery was made by Nelson Caldwell of the Harvard-Smithsonian Center for Astrophysics and his team while studying the space around the supergiant elliptical galaxy M87. Caldwell and colleagues think M87 might have two supermassive black holes at its center. The star cluster wandered too close to the pair, which picked off many of the cluster’s outer stars while the inner core remained intact. The black holes then acted like a slingshot, flinging the cluster away at a tremendous speed."

+ - Astronomers Discover Pair of Black Holes in Inactive Galaxy

Submitted by William Robinson
William Robinson (875390) writes "The Astronomers at XMM-Newton have detected a pair of supermassive black holes at the center of an inactive galaxy. Most massive galaxies in the Universe are thought to harbor at least one supermassive black hole at their center. And a pair of black holes is indication of strong possibility that the galaxies have merged. Finding black holes in quiescent galaxies is difficult because there are no gas clouds feeding the black holes, so the cores of these galaxies are truly dark. It can be only detected by this ‘tidal disruption event’,."

+ - NASA proposes "water world theory" for origin of life

Submitted by William Robinson
William Robinson (875390) writes "A new study from researchers at Nasa's Jet Propulsion Laboratory has proposed the "water world" theory as the answer to our evolution, which describes how electrical energy naturally produced at the sea floor might have given rise to life. While the scientists had already proposed this hypothesis called "submarine alkaline hydrothermal emergence of life" the new report assembles decades of field, laboratory and theoretical research into a grand, unified picture."

+ - Organ regenerated inside a living animal for the first time->

Submitted by ananyo
ananyo (2519492) writes "Scientists at Edinburgh University have successfully persuaded an organ to regenerate inside an animal. As they report in the journal Development, they have treated, in mice, an organ called the thymus, which is a part of the immune system that runs down in old age. Instead of adding stem cells they have stimulated their animals’ thymuses to make more of a protein called FOXN1. This is a transcription factor (a molecular switch that activates genes).
The scientists knew from earlier experiments that FOXN1 is important for the embryonic development of the thymus, and speculated that it might also rejuvenate the organ in older animals. They bred a special strain of mice whose FOXN1 production could be stimulated specifically in the thymus by tamoxifen, a drug more familiar as a treatment for breast cancer.
In one-year-olds, stimulating FOXN1 production in the thymus caused it to become 2.7 times bigger within a month. In two-year-olds the increase was 2.6 times. Moreover, when the researchers studied the enlarged thymuses microscopically, and compared them with those from untreated control animals of the same ages, they found that the organs’ internal structures had reverted to their youthful nature."
