REPLAB: A low-cost benchmark platform for robotic learning

Researchers at UC Berkeley have developed a reproducible, low-cost and compact benchmark platform to evaluate robotic learning approaches, which they called REPLAB. Their recent study, presented in a paper pre-published on arXiv, was supported by Berkeley DeepDrive, the Office of Naval Research (ONR), Google, NVIDIA and Amazon.

Image: Hubble sees a galaxy bucking the trend

This luminous orb is the galaxy NGC 4621, better known as Messier 59. As this latter moniker indicates, the galaxy is listed in the famous catalog of deep-sky objects compiled by French comet-hunter Charles Messier in the 18th century. However, German astronomer Johann Gottfried Koehler is credited with discovering the galaxy just days before Messier added it to his collection in 1779.

More opioids given than prescribed in emergency department

(HealthDay)—The rate of emergency department visits with opioids only given during the visit is higher than the rate for visits with opioids only prescribed at discharge and for visits with opioids given and prescribed, according to a May data brief published by the U.S. Centers for Disease Control and Prevention National Center for Health Statistics.

More than half of patients in pain management study took no opioids after operations

The opioid epidemic has become a public health crisis in the U.S. While primary care physicians have been writing fewer opioid prescriptions over the last several years, new opioid prescriptions by surgeons increased 18 percent from 2010-2016. However, many surgeons are now diligently working to change their prescribing practices. One approach has been to try reducing excessive opioid prescriptions by exploring pain management strategies that include fewer or no opioids at all for surgical patients.

Desalinating water in a greener and more economical way

We know that excessive consumption, industrial activity and growth in the global population are some of the factors threatening access to drinking water for an increasing proportion of people around the world. According to UNESCO figures from 2012, almost 700 million people suffer from limited access to water—and that number could rise to 1.8 billion by 2025. Desalination and the treatment of industrial wastewater can produce large amounts of drinking water, and these methods are already used in many countries and regions such as the United Arab Emirates, Saudi Arabia, China, Europe and the U.S.. However, existing systems are costly and use a lot of energy. Jeff Ong, from EPFL's Laboratory of Inorganic Synthesis and Catalysis, has developed a water treatment machine that combines the benefits of all of the main technologies currently being used while offering improved performance. For example, the prototype removes more than 99.9 percent of the salt from seawater with the same throughput but using less energy. The system will be tested in real-world conditions this year.

Early genome catastrophes can cause non-smoking lung cancer

Catastrophic rearrangements in the genome occurring as early as childhood and adolescence can lead to the development of lung cancer in later years in non-smokers. This finding, published in Cell, helps explain how some non-smoking-related lung cancers develop.

Scientists demonstrate plant stress memory and adaptation capabilities

Russian and Taiwanese scientists have discovered a connection between the two signaling systems that help plants survive stress situations, demonstrating that they can remember dangerous conditions that they have experienced and adapt to them. This memory mechanism will help improve agricultural plants, making them more resistant to drought, flooding, high humidity and extreme temperatures.

Uncovering microgel mysteries

Researchers at Shinshu University successfully recorded previously unexplained behavior of hydrogel microspheres (microgels) using a newly customized tool: temperature-controlled high-speed atomic force microscopy (TC HS AFM). This machine, which is the only one in the world, was assembled by Dr. Takayuki Uchihashi of Nagoya University to investigate proteins. It was applied for the first time to the study of microgels by the team at Daisuke Suzuki Laboratory, Graduate School of Textile Science & Technology and RISM (Research Initiative for Supra-Materials) of Shinshu University. The study lead by first year doctoral candidate, Yuichiro Nishizawa, succeeded in observing the structure of the microgels which had been difficult due to limitations of previous equipment.

Entrectinib gets edge over crizotinib against ROS1+ lung cancer

Crizotinib and entrectinib are both active against ROS1+ non-small cell lung cancer. But which is best? The answer seems easy: Just compare the drugs' clinical trial results. However, not all trials are created equal, and these differences in trial designs can lead to irrelevant comparisons—like comparing athletes' running times without noting that one ran a kilometer while the other ran a mile. Now results from an innovative, "virtual" clinical trial presented at the American Society for Clinical Oncology (ASCO) Annual Meeting 2019 attempt to place crizotinib and entrectinib on an equal playing field. In this analysis, patients taking entrectinib were able to stay on treatment longer and had about almost 6 months longer progression-free survival than patients treated with crizotinib.
