Experimental results from the XENON1T dark matter detector limit the effective size of dark matter particles to 4.1X10-47 square centimeters–one-trillionth of one-trillionth of a centimeter squared–the most stringent limit yet determined for dark matter as established by the world’s most sensitive detector.

Analysis scours 276 days of data from world’s most sensitive detector. Experimental results from the XENON1T dark matter detector limit the effective size of dark matter particles to 4.1 x 10-47 square centimeters – one-trillionth of one-trillionth of a centimeter squared – the most stringent limit yet determined for dark matter as established by the world’s most sensitive detector.

When scientists at The University of Texas Health Science Center at Houston (UTHealth) applied a chemical found in soybeans to a non-steroidal anti-inflammatory drug (NSAID), they increased its anticancer properties and reduced its side effects. Findings of the preclinical study of phosphatidylcholine, also called lecithin, appear in the journal Oncology Letters. “The results support the potential use of NSAIDs associated with phosphatidylcholine for the prevention and treatment of colorectal cancer,” said Lenard Lichtenberger, Ph.D., the study’s lead investigator and a professor of integrative biology and pharmacology at McGovern Medical School at UTHealth.

Researchers engineered a cell-like structure that harnesses photosynthesis to perform designer reactions. In the quest to build an artificial cell, there are two approaches: The first, reengineers the genomic software of a living cell. The second, focuses on cellular hardware, building simple, cell-like structures from the ground up that mimic the function of living cells...

A new tool opens the possibility of creating drugs that can be taken conveniently as pills to correct genetic diseases. As scientists gain insights into which genes drive diseases, they are pursuing the next logical question: Can gene editing technologies be developed to treat or even cure those diseases? Much of that effort has focused on developing technologies such as CRISPR-Cas9, a protein-based system.

At The Scripps Research Institute campus in Florida, chemist Matthew D. Disney, PhD, has taken a different approach, developing a small-molecule-based tool that acts on RNA to selectively delete certain gene products...
