On Thursday, SpaceX announced that it is planning to launch its Falcon 9 rocket on December 19, 2015. It will be the first mission the company will attempt for after the massive explosion of its space station cargo six months ago.

SpaceX CEO Elon Musk on Thursday also said that the company is planning to test fire Falcon 9’s main engines on Wednesday at Launch Complex 40, then launch about three days later.

The launch scheduled to take place on December 19 would be SpaceX’s first since a Falcon 9 rocket exploded two minutes after its liftoff on June 28. The cargo was all set to take necessary supplies to the International Space Station (ISS). The strut in the rocket’s upper-stage oxidizer tank was blamed for the accident.

A team of astronomers recently discovered a small star which has huge storm. The storm is as big as Jupiter’s Great Red Spot, said researchers who detected the tiny star using NASA’s Spitzer and Kepler space telescopes.

John Gizis of the University of Delaware, Newark, said the star they discovered is almost the size of Jupiter, and its storm is the size of Jupiter's Great Red Spot.

Gizis, the lead author of a new study appearing in the Astrophysical Journal, said, “We know this newfound storm has lasted at least two years, and probably longer”.

A new study published on Wednesday in the Lancet finds that the widely held view that happiness enhances health and longevity is actually groundless. Researchers, for the study, followed approximately one million middle-aged women in Britain for 10 years.

The study researchers concluded that happiness and related measures of well-being do not have any direct effect on mortality.

Sir Richard Peto, an author of the study and a professor of medical statistics and epidemiology at the University of Oxford said he and his fellow researchers decided to look into the subject because of the widespread belief that stress and unhappiness causes diseases.

A team of researchers in the United States created the world’s first litter of puppies through in vitro fertilization (IVF). The researchers believe this breakthrough could help to eradicate disease in dogs and in humans as well.

Dr. Alexander Travis, who runs the lab at the Baker Institute for Animal Health at Cornell University’s College of Veterinary Medicine in Ithaca, New York, said they gently handled a puppy and cleaned it with a towel. Crying of the puppy was an approval for their success.

Just after the birth, eyes of puppies were closed. They were adorable, cute with smooshed-in faces. Doctors examined them to see if they were normal and were breathing properly.

A new report from the Centers for disease Control and Prevention (CDC) has shown that life expectancy for a newborn is about 79 years for the third consecutive year in a row.

The 2014 mortality report by the CDC showed that infant mortality in the United States was at a historic low i.e. 582.1 infant deaths per 100,000 live births. The report showed that ten overall causes of deaths for infants in 2013 to 2014 remained the same.

The researchers found differences in the number of deaths due to unintentional injuries, Alzheimer’s disease, stroke and suicide, and found that all of these were increasing. On the other hand, the number of deaths from cancer, diabetes, chronic lower respiratory disease, diabetes, influenza and pneumonia are found to be decreasing, said health officials.

It seems great to know that sponge-filled syringe to treat gunshot wounds has now been approved to treat civilians too, which has already been approved for military use in 2014. The unique syringe can become lifesaver for gunshot wounds in just 20 seconds by restraining domestic gunshot fatalities that have been increased tremendously over the years. The syringe, called XSTAT 30, squirts out 92 tiny, compressed cellulose sponges coated with a blood-sopping absorbent.

The biggest challenge that comes in treating gunshot victims is to stop bleeding. According to FDA, 40% of civilians die from a traumatic injury because of hemorrhage or escape of blood from vessels.
