Astronomers are convinced these are the 2 major players in the universe. Dark matter, pulling the universe together, & dark energy, pushing it apart. They’re engaged in a cosmic tug of war that will determine nothing less than the fate of our universe.

It's NOVA Trivia Time! NOVA wonders... The expansion of the universe is accelerating! Something must be speeding it up. What is?

While it won’t be anything like the 2017 total solar eclipse, there is a partial solar eclipse coming up this week.


The July 13 eclipse is particularly rare because it will occur on Friday the 13th.



There has not been a solar eclipse on Friday the 13th since December 13, 1974, according to NASA. And the next partial eclipse to occur on Friday the 13th will be on September 13, 2080.


People in Tasmania, an island off the southern coast of Australia, will most likely get the best view of the July 13 eclipse, which is expected to last one hour and four minutes. The best place to see it may be in Hobart, Tasmania, where about 35% of the sun’s diameter will be covered by the moon at 1:24 p.m. local time, according to the UK’s Nautical Almanac Office.

Cancer cells slaying their own kin
https://www.sciencenews.org/article/cancer-cells-engineered-crispr-slay-their-own-kin


"Using gene editing, scientists have hoodwinked tumor cells into turning against their own kind.

Cancer cells circulating in the bloodstream have something of a homing instinct, able to find and return to the tumor where they originated. To capitalize on that ability, researchers engineered these roving tumor cells to secrete a protein that triggers a death switch in resident tumor cells they encounter. The cancer-fighting cancer cells also have a built-in suicide switch — so the weaponized cells self-destruct before they can start tumors of their own, the team reports in the July 11 Science Translational Medicine.

The new study isn’t the first attempt to fight cancer with cancer. Previous research has used circulating tumor cells to deliver cancer-killing viruses to noncirculating tumor cells, for example. But the new approach uses a gene-editing technology called CRISPR/Cas9 to manipulate the offensive-line cancer cells and give them more sophisticated properties, such as the ability to self-destruct once no longer needed.
