Nowhere left to hide for Planet Nine

Astronomers could discover the solar system’s mystery ninth planet by 2019, scientists have claimed.

Dubbed Planet Nine, the elusive world is believed by many to be responsible for the strange shaped orbits of objects in the outer realms of the solar system, but it is yet to be seen.

But with up to 10 research groups scouring the skies, astronomers believe it won’t remain hidden for long and could be discovered in the next 16 months.

The claims were made by astronomer Mike Brown, one of those who proposed the existence of the mystery world.

‘I'm pretty sure, I think, that by the end of next winter – not this winter, next winter – I think that there'll be enough people looking for it that … somebody's actually going to track this down,’ said Professor Brown.

The mystery world was first proposed by Professor Brown’s team to account for the long elliptical orbit of frigid objects in the extending out beyond the Kuiper belt past Pluto – whose planetary status was in part killed off by Professor Brown’s team.

But with a number of research groups dedicated to finding evidence of the planet and some of the world’s most advanced telescopes could help pinpoint it in the night sky.

FDA approves Merck's lung cancer drug as first-line treatment

Merck & Co Inc said the U.S. Food and Drug Administration has approved its immunotherapy Keytruda for use in certain previously untreated lung cancer patients, making it the only approved first-line treatment.

The drug has been approved for treating metastatic non-small cell lung cancer (NSCLC) patients with high-levels of a protein known for suppressing the immune system called PD-L1, according to Reuters.

Keytruda works by taking the brakes off the immune system by blocking the interaction between PD-L1 and another protein, PD-1. The drug has already been approved for patients who have undergone previous chemotherapy for advanced non-small lung cancer.

Smart mouth: Chinese fish fossil sheds light on jaw evolution

A bottom-dwelling, mud-grubbing, armored fish that swam in tropical seas 423 million years ago is fundamentally changing the understanding of the evolution of an indisputably indispensable anatomical feature: the jaw.

Scientists said they unearthed in China's Yunnan province fossils of a primordial fish called Qilinyu rostrata that was about 12 inches (30 cm) long and possessed the telltale bones present in modern vertebrate jaws including in people, according to Reuters.

Stone Age people 'roasted rodents for food' – archaeologists

Rodents appear to have been roasted for food by Stone Age people as early as 5,000 years ago, archaeological evidence suggests.

Bones from archaeological sites in Orkney show voles were cooked or boiled for food, or possibly for pest control,  according to BBC.

This is the first evidence for the exploitation of rodents by Neolithic people in Europe, say scientists.

Rodents were consumed later in history, with the dormouse regarded as a delicacy during Roman times.

Lost Mars lander fell 2-4 km, destroyed on impact – NASA images

Schiaparelli, the landing craft from the European Space Agency’s Exomars probe, which went missing earlier this week near the surface of Mars, has apparently been destroyed, according to new data.

The ESA craft fell to the Mars surface from a height of 2 to 4 kilometers (1.2 to 2.5 miles), the agency said. The disc-shaped spacecraft, which weighed 577 kilos (1,272 lb) was destroyed on impact, according to RT.
