Lucy mission completes critical design review

The Lucy mission led by Southwest Research Institute is one step closer to its 2021 launch to explore the Trojan asteroids, a population of ancient small bodies that share an orbit with Jupiter. With the successful completion of its critical design review last week, the Lucy spacecraft is on track to begin a 12-year journey of almost 4 billion miles to visit a record-breaking seven asteroids—one main belt asteroid and six Trojans.

Resistance to last resort drug arose in patient over 3 weeks

French investigators have described development of resistance to one of the last resort therapies used to treat extremely drug-resistant Pseudomonas aeruginosa. That resistance arose in a single patient over a scant 22 days. They subsequently identified the single nucleotide mutation in P. aeruginosa that caused the resistance. The research is published in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.

NASA's James Webb Space Telescope clears critical sunshield deployment testing

The sunshield for NASA's James Webb Space Telescope has passed a test critical to preparing the observatory for its 2021 launch. Technicians and engineers fully deployed and tensioned each of the sunshield's five layers, successfully putting the sunshield into the same position it will be in a million miles from Earth.

Lead pollution from Native Americans attributed to crushing galena for glitter paint

Native American use of galena at Kincaid Mounds, a settlement occupied during the Mississippian period (1150 to 1450 CE), resulted in more than 1.5 metric tons of lead pollution deposited in a small lake near the Ohio River. New data from IUPUI researchers found the lead did not originate from this Southern Illinois settlement, but instead was brought to the site from other Midwest sources.

Climate warming promises more frequent extreme El Niño events

El Niño events cause serious shifts in weather patterns across the globe, and an important question that scientists have sought to answer is: how will climate change affect the generation of strong El Niño events? A new study, published today in the Proceedings of the National Academy of Science by a team of international climate researchers led by Bin Wang of the University of Hawaii's International Pacific Research Center (IPRC), has an answer to that question. Results show that since the late 1970's, climate change effects have shifted the El Niño onset location from the eastern Pacific to the western Pacific and caused more frequent extreme El Niño events. Continued warming over the western Pacific warm pool promises conditions that will trigger more extreme events in the future.

Catastrophic events carry forests of trees thousands of miles to a burial at sea

Flooding from torrential rains caused by cyclones and monsoonal storms, as well as other catastrophic events, are responsible for moving huge amounts of fresh wood to a watery grave deep under the ocean, according to Earth scientists.

Comparisons of 4.7 million mtDNA sequences show GenBank is reliable for animal IDs

Did a murderer walk through the room? Did a shark just swim by? Is this a poisonous mushroom? Which reef species are lost when the coral dies? These questions can potentially be answered quickly and cheaply based on tiny samples of DNA found in the environment. But identifying DNA requires a trustworthy library of previously identified DNA sequences for comparison. Smithsonian scientists and their colleagues analyzed more than 4.7 million animal DNA sequences from GenBank, the most commonly used tool for this purpose, and discovered that animal identification errors are surprisingly rare—but sometimes quite funny.

Uncovering the principles behind RNA folding

A Northwestern Engineering research team led by Professor Julius Lucks has uncovered a new understanding of how RNA molecules act as cellular 'biosensors' to monitor and respond to changes in the environment by controlling gene expression. The findings could impact the design of future RNA-specific therapeutics as well as new synthetic biology tools that measure the presence of toxins in the environment.

Fuel injection helps reduce magnetic island instabilities

Fusion is a non-carbon-based process for energy production, where lighter atoms fuse into heavier ones. Fusion reactors operate by confining a "soup" of charged particles, known as a plasma, within powerful magnetic fields. But these magnetic fields must contain the plasma long enough that it can be heated to extreme temperatures—hotter than the sun—where fusion reactions can occur.

Lab-grown meat: Researchers grow muscle cells on edible fibers

Lab-grown or cultured meat could revolutionize food production, providing a greener, more sustainable, more ethical alternative to large-scale meat production. But getting lab-grown meat from the petri dish to the dinner plate requires solving several major problems, including how to make large amounts of it and how to make it feel and taste more like real meat.

Record-number of over 200,000 galaxies confirm: Galaxy mergers ignite star bursts

When two galaxies merge, there are brief periods of stellar baby booms. A group of astronomers led by Lingyu Wang (SRON Netherlands Institute for Space Research) has now used a sample of over 200,000 galaxies to confirm that galaxy mergers are the driving force behind star bursts. It is the first time that scientists have used artificial intelligence in a galaxy merger study. The results are published in Astronomy & Astrophysics on October 21st.

Study: 20% of patients are prescribed opioids after cardiac device implantation surgery

One in five patients is prescribed opioids after having a pacemaker or similar device implanted, according to a large US study conducted at Mayo Clinic published in HeartRhythm, the official journal of the Heart Rhythm Society and the Cardiac Electrophysiology Society published by Elsevier. Eighty percent of patients who were prescribed opioids had never taken them before. Investigators stress the importance of improving postoperative pain management following cardiac device procedures to reduce use of prescription opioids.

Data mining applied to scholarly publications to finally reveal Earth's biodiversity

At a time when a million species are at risk of extinction, according to a recent UN report, ironically, we don't know how many species there are on Earth, nor have we noted down all those that we have come to know on a single list. In fact, we don't even know how many species we would have put on such a list.
