By signing the Agriculture Improvement Act of 2018, colloquially called the Farm Bill, President Donald Trump removed industrial hemp from the controlled substances list. For the first time in over 80 years, farmers can grow and sell industrial hemp.

Since microRNAs are key regulators of biological processes, a microRNA cluster that regulates synaptic strength and is involved in the control of social behavior in mammals may be a new path toward therapeutic strategies for the treatment of social deficits in neurodevelopmental disorders such as autism spectrum disorder or schizophrenia. 

DNA is first copied to make messenger RNA molecules (mRNAs) that are then translated into protein. MicroRNAs are short snippets of RNA that do not code for a protein. Instead, they function mainly by regulating the stability or translation rate of mRNAs, inhibiting the production of particular proteins. Each microRNA typically targets hundreds of different mRNAs, making them ideal for coordinating complex cellular processes.

The ichthyosaur (literally ‘fish-lizard’) lived in what is today southern Germany during the Jurassic Period some 180 million years ago. The two-meter long reptile swam in the vast ocean that is now, after climate and geological changes, Europe.

Researchers have analyzed the remains of an ichthyosaur so well-preserved that its soft-tissues retain some of their original pliability; the most comprehensive and in-depth examination of a soft-tissue fossil ever undertaken. Among other things, the study reveals that the soft parts have fossilized so quickly that both the original cells and their internal contents are preserved.

A distant planet has an abundance of helium in its atmosphere so great that it has swollen to resemble an inflated balloon.

The helium of HAT-P-11b, 124 light years from Earth and in the Cygnus constellation, is blown away from the day side of the planet to its night side at over 10,000 km an hour. Because it is such a light gas, it escapes easily from the attraction of the planet and forms an extended cloud all around it.

The Carr Fire in Shasta and Trinity Counties began July 23rd, 2018 after a tire blew out on a trailer and the rim made sparks on the pavement. setting dry vegetation in an area historically dry ablaze.

That's simple bad luck but it caused 359 square miles to burn, estimated to be the seventh largest fire in recorded California history. By the end of August it was contained but not before it led to eight fatalities and destroyed 1,079 residences. 

Infertility affects about 10 percent of couples and among them are one in 500 women with congenital defects in their uterus or a medical issue that caused damage. In the past, that meant adoption but recently uterus transplants became possible. In 2013, Sweden performed the first and since then there have been 39, resulting in 11 live births.

But those were living donors, and that is going to be rare because uterus donation is only available for women with friends or family members who will donate.
