Glioblastoma multiforme (GBM) is a brain cancer that kills approximately 13,000 Americans a year. It is aggressive and incurable.

A research team has demonstrated delivery of a therapeutic delivered using nanotechnology that turns off a critical gene in this complex cancer, increasing survival rates significantly - in animals.

The drug is designed to target a specific cancer-causing gene in cells. The drug simply flips the switch of the troublesome oncogene to "off," silencing the gene, which knocks out the proteins that keep cancer cells immortal. 

Kepler-78b is a planet that shouldn't exist because the blazing hot lava world circles its star every 8.5 hours at a distance of less than one million miles - one of the tightest known orbits. According to current beliefs about planet formation, it couldn't have formed so close to its star, nor could it have moved there.

Kepler-78b a mystery world. And it is doomed. 

A newly discovered planet, Kepler-78b, is in the constellation of Cygnus but it's a lot like Earth. If Earth were 2,000 degrees hotter and orbited the sun every 8 hours. 

But otherwise it is a lot like our planet, about 20% larger and 169% of our mass, and that makes it the smallest exoplanet to-date that has a confirmed mass and radius. The size is about the same, the density is about the same - and that's part of the mystery. How did it form so close to its star?

The sun emitted another significant solar flare, peaking at 5:54 p.m. on Oct. 29th, 2013  – the fourth X-class flare in the last week.

Solar flares are powerful bursts of radiation and while the radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, when intense enough they can disturb the atmosphere in the layer where GPS and communications signals travel. The disruption to radio signals occurs for as long as the flare is ongoing, anywhere from minutes to hours.

This flare is classified as an X2.3 class flare. "X-class" denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.

A new collection featuring research on the complex evolutionary cascade theory that made the unique gigantism of sauropod dinosaurs possible has now been published in PLOS ONE.

Sauropod dinosaurs were the largest terrestrial animals to roam the Earth, exceeding all other land-dwelling vertebrates in both mean and maximal body size. While convergently evolving many features seen in large terrestrial mammals, such as upright, columnar limbs and barrel-shaped trunks, sauropods evolved some unique features, such as the extremely long necks and diminutive heads they are famous for.

The Large Underground Xenon (LUX) experiment is trying to identify the nature of dark matter, an invisible substance that physicists believe is all around us, making up most of the matter in the universe, even though it has effect on our lives.

The umbrella term 'dark matter' encompasses about 25% of the Universe, while what we know as matter makes up about 5%. The rest consists of what is called "dark energy" and no one knows anything about that other than that it is something helps make gravity behave strangely at the very large scale.
