2018 October 11 – Huge reductions in meat-eating are essential to avoid dangerous climate change, according to the most comprehensive analysis yet of the food system’s impact on the environment. In western countries, beef consumption needs to fall by 90% and be replaced by five times more beans and pulses.
The research also finds that enormous changes to farming are needed
to avoid destroying the planet’s ability to feed the 10 billion people
expected to be on the planet in a few decades.
Food production already causes great damage to the environment, via greenhouse gases from livestock, deforestation and water shortages from farming, and vast ocean dead zones from agricultural pollution. – theguardian.com
2018 Sept 26 – The researchers used a wealth of data gathered over 100 years to build mathematical models to trace the causes of the wobble and found that three factors are at play, and mankind is responsible for one of them. Two of the three factors identified by the scientists are glacial rebound and mantle convection.
Glacial rebound happens when thick ice sheets physically push down on land masses, compressing them, but then release that pressure upon melting. The land then balloons back up over time, causing Earth’s spin to wobble as if slightly off-axis. The effects of the last ice age, which would have compressed a huge amount of land across many continents, is still being felt today in the form of glacial rebound.
Mantle convection, the other uncontrollable factor in Earth’s wobble, relates to our planet’s inner workings. The plates on Earth’s surface are in constant flux due to the movement of liquid rock far beneath our feet. The researchers believe these currents also contribute to the planet’s imperfect spin.
The third and final factor identified by the scientists is the massive loss of ice on Greenland and other areas, which is the direct result of global warming thanks to human activities. The researchers estimate that Greenland has lost roughly 7,500 gigatons, or 7,500,000,000,000 metric tons of ice due to global warming. All that ice loss has happened in the 20th century, and greenhouse gas production has been cited as the primary culprit. Losing all that mass has caused a significant shift on the planet and has contributed to the wobble as well. – bgr.com
2018 Sept 24 – Sir Michael Atiyah is set to present his “simple proof” of the Riemann hypothesis on Monday at the Heidelberg Laureate Forum in Germany. The hypothesis is intimately connected to the distribution of prime numbers, those indivisible by any whole number other than themselves and one,” reports New Scientist. “If the hypothesis is proven to be correct, mathematicians would be armed with a map to the location of all such prime numbers, a breakthrough with far-reaching repercussions in the field.” – soylentnews.org
2018 Sept 23 – Two tiny hopping robots have successfully landed on an asteroid called Ryugu — and they’ve even sent back some wild postcards from their new home. The tiny rovers are part of the Japan Aerospace Exploration Agency’s Hayabusa2 asteroid sample-return mission. Engineers with the agency deployed the robots early Friday (Sept. 21), but JAXA waited until today (Sept. 22) to confirm the operation was successful and both rovers made the landing safely.
In order to complete the deployment, the main spacecraft of the Hayabusa2 mission lowered itself carefully down toward the surface until it was just 180 feet (55 meters) up. After the rovers were on their way, the spacecraft raised itself back up to its typical altitude of about 12.5 miles above the asteroid’s surface (20 kilometers). The agency still has two more deployments yet to accomplish before it can rest easy: Hayabusa2 is scheduled to deploy a larger rover called MASCOT in October and another tiny hopper next year. And of course, the main spacecraft has a host of other tasks to accomplish during its stay at Ryugu — most notably, to collect a sample of the primitive world to bring home to Earth for laboratory analysis.
2018 September 19 – A new study has sifted through some of the largest online data sets of personality quizzes and identified four distinct “types” therein.
Average: These people score high in neuroticism and extraversion, but score low in openness. It is the most typical category, with women being more likely than men to fit into it.
Reserved: This type of person is stable emotionally without being especially open or neurotic. They tend to score lower on extraversion but tend to be somewhat agreeable and conscientious.
Role Models: These people score high in every trait except neuroticism, and the likelihood that someone fits into this category increases dramatically as they age. “These are people who are dependable and open to new ideas,” says Amaral. “These are good people to be in charge of things.” Women are more likely than men to be role models.
Self-Centered: These people score very high in extraversion, but score low in openness, agreeableness, and conscientiousness. Most teenage boys would fall into this category, according to Revelle, before (hopefully) maturing out of it. The number of people who fall into this category decreases dramatically with age. – arstechnica.com

2018, Aug 26 – Research shows sleep deprivation or excessive hours in bed increase risk of coronary artery disease or stroke. From a report: Six to eight hours of sleep a night is most beneficial for the heart, while more or less than that could increase the risk of coronary artery disease or a stroke, researchers have suggested. Data from more than a million adults from 11 studies was analysed as part of the research. – theguardian.com

The mission’s findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts on orbit, disrupt radio communications and, at their most severe, overwhelm power grids. The spacecraft will transmit its first science observations in December. – nasa.gov
2018 August 10 – British oceanographers now believe that “rogue waves” are responsible for the disappearance of a number of ships in the region. They’re abnormally large and unexpected waves in open sea.

2018 July 27 – The worms were found among more than 300 samples of frozen soil pulled from the Kolyma River Lowlands in Northeastern Siberia by the researchers. One sample from a buried squirrel burrow dating back 32,000 years and one from a glacier dating back 40,000 years. After isolating intact nematodes, the scientists kept the samples at 68 degrees Fahrenheit and left them surrounded by food in a petri dish, just to see what would happen. Over the next few weeks, they gradually spotted flickers of life as the worms ate the food and even cloned new family members. These cloned worms were then cultured separately, and they too thrived. – gizmodo.com
2018 July 20 – Stanford researchers have figured out how much cortisol someone is producing in seconds, using sweat from the skin. A wearable membrane allows charged ions, like sodium and potassium, to pass through. Cortisol, which has no charge, can’t pass, and instead blocks the charged ions. Signals sent from an electrical sensor in the patch can be used to detect these and determine how much cortisol is in the sweat. – ieee.org
2018 July 19 – Scientists at HHMI’s Janelia Research Campus have taken detailed pictures of the entire brain of an adult female fruit fly using transmission electron microscopy. The fruit fly brain, roughly the size of a poppy seed, contains about 100,000 neurons (humans have 100 billion). Each neuron branches into a starburst of fine wires that touch the wires of other neurons. Neurons talk to one another through these touchpoints, or synapses, forming a dense mesh of communication circuits. – hhmi.org
