HOUSTON - (April 18, 2016) - Thank the little "muscles" in your neurons for allowing you to remember where you live, what your friends and family look like and a lot more.

New research at Rice University suggests actin filaments that control the shape of neuron cells may also be the key to the molecular machinery that forms and stores long-term memories.

The Rice lab of theoretical biological physicist Peter Wolynes reported in the Proceedings of the National Academy of Sciences a theory about how long-term memories are made; the theory is based on simulations that analyze the energy landscapes of the proteins involved.

You can never predict what treasure might be hiding in your own basement - a year ago, a 1917 image on an astronomical glass plate from the Carnegie Observatories' collection shows the first-ever evidence of a planetary system beyond our own Sun. 

Here's what happened: about a year ago, the review's author, Jay Farihi of University College London, contacted our Observatories' Director, John Mulchaey. He was looking for a plate in the Carnegie archive that contained a spectrum of van Maanen's star, a white dwarf discovered by Dutch-American astronomer Adriaan van Maanen in the very year our own plate was made.

With the help of a small stool, Mercy Carrion clambers onto an examination table. The obese 50-year-old woman stands just 115.6 cm (3’9.5’’) tall. Despite being overweight, Mercy shows no sign of developing diabetes and has remarkably low blood pressure at 100/70. “That’s why they don’t care much about their weight,” says her doctor, Jaime Guevara-Aguirre.

Mercy, who has a rare genetic disorder, is one of his long-term patients. She and her peers know they are in some way protected from diabetes, cancer and a number of other diseases that threaten the rest of us as we age. As such, they have a happy-go-lucky attitude towards health and fitness.

Methane, the abundant and inexpensive natural gas, is often burnt off around the world at oil fields and refineries but it's a great energy source and base material for the chemical industry, if only there was a viable way to put it in liquid form, which is easier to transport and more reactive.

A phase I study of the drug LOXO-101 appears to significantly reduce tumors in patients with varied types of genetically defined cancer, according to a study led by The University of Texas MD Anderson Cancer Center.

The results of the study, which followed patients with unique proteins called tropomyosin receptor kinase fusions (TRKs), were presented at the American Association for Cancer Research's annual meeting held April 16-20 in New Orleans.

"We saw efficacy with significant tumor regression in all six TRK fusion patients enrolled in the study," said David Hong, M.D., associate professor of Investigational Cancer Therapeutics. "We were surprised by the fact that the study demonstrated efficacy in every one of the TRK fusion-positive patients."

Researchers have characterized the prevalence and risk factors of fatty liver disease in patients who undergo liver transplantation. The findings, which are published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases, could have important implications for safeguarding transplant recipients' health.

When people take the psychedelic drug LSD, they sometimes feel as though the boundary that separates them from the rest of the world has dissolved. Now, the first functional magnetic resonance images (fMRI) of people's brains while on LSD help to explain this phenomenon known as "ego dissolution."

As researchers report in the Cell Press journal Current Biology on April 13, these images suggest that ego dissolution occurs as regions of the brain involved in higher cognition become heavily over-connected. The findings suggest that studies of LSD and other psychedelic drugs can produce important insights into the brain. They can also provide intriguing biological insight into philosophical questions about the very nature of reality, the researchers say.

When we published a paper in 2013 finding 97% scientific consensus on human-caused global warming, what surprised me was how surprised everyone was.

Ours wasn’t the first study to find such a scientific consensus. Nor was it the second. Nor were we the last.

In a new study, environmental pollutants found in fish were shown to obstruct the human body's natural defense system to expel harmful toxins. The Scripps Institution of Oceanography at UC San Diego-led research team suggests that this information should be used to better assess the human health risks from eating contaminated seafood. The study was published in the April 15 issue of the journal Science Advances.

A protein found in cells of nearly all plants and animals, called P-gp, acts as the cell's bouncer by expelling foreign chemicals from the body. P-gp is well known for its ability to transport therapeutic drugs out of cancer cells and, in some cases, rendering these cells resistant to multiple drugs at once.
