 Per Aspera Ad Astra
Los Angeles CA (SPX) Sep 21, 2019
I have always known what the phrase "Per Aspera Ad Astra" meant, and in my work in the Aerospace arena, I have come to appreciate its significance.
And so, any film that would attempt a title as such has to live up to my expectations and Ad Astra the movie does.
Actor Brad Pitt and the cast masterfully demonstrate what a near-future voyage to the Moon, Mars and outer solar system mig

 Climate change study finds that maple syrup season may come earlier
Once winter nights dip below freezing and the days warm up above freezing sap begins to flow in sugar maples marking the start of the syrup season. With climate change, daily temperatures are on the rise, which affects sap flow and sugar content. By 2100, the maple syrup season in eastern North America may be one month earlier than it was during 1950 and 2017, according to a new study.

Short Sleeper Syndrome: When You Can Get By on Just a Few Hours of Sleep
A small segment of the population are born with superhuman sleep needs. They're called natural short sleepers, and they wake up refreshed and wide awake on very little sleep. And these individuals share a few other quirks, too. (Credit: Shutterstock)

World's first gene therapy for glycogen storage disease produces remarkable results
The rare and deadly genetic liver disorder, GSD type Ia, affects children from infancy through adulthood, causing dangerously low blood sugar levels and constant dependence on glucose consumption in the form of cornstarch every few hours for survival. If a cornstarch dose is missed, the disease can lead to seizures and even death. A clinical trial originally set out to simply test the safety and dosage of the gene therapy for three patients with GSD Type Ia. The dramatic improvement in their liv

Division by subtraction: Extinction of large mammal species likely drove survivors apart

Untapped resource, or greenhouse gas threat, found below rifting axis off Okinawa coast
Using an automated method to create a high-resolution map of the seismic velocity below the seafloor, researchers found a large-scale gas reservoir in an area where the Earth's upper layers are being separated. This reservoir, the first of its kind, and the potential for others like it could have implications from natural resource or environmental standpoints depending on whether the trapped gas is methane or carbon dioxide and whether it remains trapped.

Carbon Dioxide Conversion Challenge could help human explorers live on Mars
Greenbelt MD (SPX) Sep 20, 2019
On Earth, plants convert carbon dioxide (CO2) into carbohydrates and oxygen - food for them and oxygen for us to breathe. There aren't plants on Mars, but there is a lot of CO2. Technology that takes abundant resources, like CO2 found on the Red Planet, and turns them into useful supplies for human explorers could be key to long-term missions on Mars.

Corrosion resistance of steel bars in concrete when mixed with aerobic microorganisms
Dissolved oxygen in pore solution is often a controlling factor determining the rate of the corrosion process of steel bars in concrete. This study reports on the corrosion resistance and polarization properties of steel bars in a mortar specimen mixed with aerobic microorganisms. The addition of the microorganisms in mortar mixtures led to higher corrosion resistance, which was confirmed by the reduced rate of oxygen permeability, based on cathodic polarization properties.

Why is the brain disturbed by harsh sounds?
Neuroscientists have analyzed how people react when they listen to a range of different sounds, the aim being to establish the extent to which repetitive sound frequencies are considered unpleasant. Their results showed that the conventional sound-processing circuit is activated but that the cortical and sub-cortical areas involved in the processing of salience and aversion are also solicited. This explains why the brain goes into a state of alert on hearing this type of sound.

Researchers find way to kill pathogen resistant to antibiotics
Researchers have demonstrated a new strategy in fighting antibiotics resistance: the use of artificial haem proteins as a Trojan horse to selectively deliver antimicrobials to target bacteria, enabling their specific and effective sterilization. The technique killed 99.9% of Pseudomonas aeruginosa, a potentially deadly, antibiotic-resistant bacterium present in hospitals. The strategy should also work for other dangerous bacteria.

Sour is the taste of summer, a taste that evokes lemonade stands and vine-ripe tomatoes. Among the five basic tastes -- the others being bitter, sweet, salty and umami -- it is arguably the most subtle. In small amounts, it adds a critical tang to an otherwise bland dish. At higher concentrations and on its own, it's unpleasant or even painful.

Drones probe dust devils to understand Mars's atmosphere

Alcohol-producing gut bacteria could cause liver damage even in people who don't drink

Their findings could help develop a screening method for early diagnosis and treatment of non-alcoholic fatty liver.

Sponge-like action of circular RNA aids heart attack recovery
Circular RNAs, like other noncoding RNAs, were thought to be nonfunctional, but recent evidence suggests otherwise. Circular RNAs may in fact act like sponges to 'soak up,' or bind, other molecules, including microRNAs and proteins, and new work supports this idea. They describe, for the first time, a circular RNA that fills a critical role in tissue repair after heart attack, thanks to its ability to soak up harmful molecules.

A protective protein that detects newly-made incomplete protein chains in higher cells is found to have a relative in bacteria. There, the protein also plays a central role in quality control which ensures that defective proteins are degraded. The functional mechanism of these Rqc2 proteins must therefore have already existed several billion years ago in the so-called last universal common ancestor. Scientists have experimentally investigated the bacterial Rqc2 relative's function.
