A new study has found that global warming and evolution have been reshaping the bodies of some American bumblebees. According to a study published on Thursday in the journal Science, the tongues of two Rocky Mountains species of bumblebees were nearly one-quarter shorter as compared to what they were 40 years back.

They have evolved in this way because climate change has changed the buffet of wildflowers they usually feed from.

The tongue of one of these species had been half the size of the bee's body, which is equal to a human tongue going down to the waist. As the flowers where the long tongue is needed have is required have diminished thus the bees didn't require that long tongue now.

According to a Nature.com report, the CRISPR/Cas9 technique is completely revolutionizing genetic research. It is a technique that has already been used to engineer crops, livestock and gasp human embryos, and scientists are hopeful that it would ultimately be used for the treatment of disease.

Scientists at the Massachusetts Institute of Technology conducted the study, published on Friday. During the study, researchers have found enzymes that can more accurately cut as compared to the CIRPSR technique, which can aim at a stretch of DNA, snip it out, and replace. This can result into extraordinary advances in medicine.

An ancient shipwreck, known as ‘Titanic of the ancient world’, has helped researchers know several things about ancient Greek. The shipwreck gave mysterious Antikythera mechanism, and still providing useful information on the lifestyles of the Greek.

Earlier, the researchers found new treasures in the form of a bronze armrest, a bone flute, glassware, an ancient board game piece and fine ceramics. According to a marine archaeologist with the Woods Hole Oceanographic Institution, the famous shipwreck isn't done revealing ancient secrets. Every time, divers dive on it, they find something amazing that reveals about 1% life in the time of Caesar, the archaeologist added.

The United States space agency, NASA, has revealed many things about Mars that are making space enthusiasts curious to know more about the planet. Now, NASA has announced that on September 28, it is going to reveal a big mystery about the Red Planet. There are chances that the space agency will confirm the presence of water on the fourth planet from the sun.

This week, three NASA scientists will deliver a new paper at European Planetary Science Congress. According to the paper, after analyzing images from the Mars Reconnaissance Orbiter, researchers found that briny water flowing on the Martian surface has resulted into seasonal dark streaks on the planet.

Many skywatchers across the globe were waiting for Sunday night to see a supermoon, the time when the moon is at its closest orbit to earth. Finally, the rare celestial event came when people could see a 14% bigger moon. Sunday’s supermoon is combined with a lunar eclipse, which made the event even more exciting.

Several people around the world enjoyed the views in the skies to observe a rare double celestial treat. People watched a total lunar eclipse turning the moon red in color.

Lunar eclipses are not rare, but it is really rare to see a supermoon eclipse. Since 1990, there were only five supermoon eclipses. The last time when stargazers at earth observed a supermoon eclipse was in 1982. According to experts, such an event will not take place until 2033.

Bristol-Myers Squibb's immunotherapy drug Opdivo has increased the kidney cancer survival rates by over 2 years in a late-stage trial, making the drug all set to be used beyond melanoma and lung cancer.

In July, the US Company said the study was stopped early because its drug was more effective as compared to Novartis' established product Afinitor. But the detailed findings of the study were revealed on Saturday at the European Cancer Congress in Vienna.

The successful outcome meant that Opdivo has become the first so-called immune checkpoint inhibitor drug that has shown an improvement in overall survival in patients having renal cell carcinoma (RCC), a common type of kidney cancer.
