Extroverted? You may have better financial outcomes

Credit: Unsplash/CC0 Public Domain You might think the way you approach money is based on financial advice or past experiences, but new research from the University of Georgia shows that your personality may have a big impact on financial decision making and risk taking. In a new study, psychology Ph.D. student Jim Exley investigates the… Continue reading Extroverted? You may have better financial outcomes

Anuvu raises $50 million for small GEO mobility constellation

TAMPA, Fla. — Investors that rescued Anuvu from bankruptcy in March have thrown $50 million behind plans for the mobile connectivity provider to have its own constellation of small geostationary-orbit (GEO) satellites. The growth capital will support the first two satellites Anuvu ordered in July from Astranis as part of a planned eight-strong constellation, building… Continue reading Anuvu raises $50 million for small GEO mobility constellation

Earth’s Early Magma Oceans Detected in 3.7 Billion Year-Old Greenland Rocks

By Helen M. Williams, University of Cambridge November 30, 2021 4 billion years ago, the Earth was composed of a series of magma oceans hundreds of kilometers deep. Earth hasn’t always been a blue and green oasis of life in an otherwise inhospitable solar system. During our planet’s first 50 million years, around 4.5 billion… Continue reading Earth’s Early Magma Oceans Detected in 3.7 Billion Year-Old Greenland Rocks

Over-60s, vulnerable should postpone travel due to Omicron: WHO

Credit: Pixabay/CC0 Public Domain The WHO said Tuesday that while blanket travel bans would not stop the spread of the Omicron variant, COVID-vulnerable people, including the over-60s, should postpone plans to travel abroad. Omicron, the new COVID-19 variant of concern which the World Health Organization says poses a “very high” risk globally, has prompted many… Continue reading Over-60s, vulnerable should postpone travel due to Omicron: WHO

Credit: University of Missouri An international team of scientists from the United States and Australia, led by Sarah Jacquet at the University of Missouri, has documented the discovery of two new species of fossilized armored worms in Australia—Lepidocoleus caliburnus and Lepidocoleus shurikenus—dating from about 400 million years ago. Then, using the micro-CT imaging… Continue reading Bringing 400-million-year-old fossilized armored worms to ‘virtual’ life

High-speed holography of cells spots physical beacons of disease

A new fast cell imaging device can analyze tens of thousands of cells per minute to spot physical signs of disease. The bottom line contains whole cells as they are identified. The middle line shows the area parameters for each cell’s scan. The top line shows the final scan of each cell, color coded to… Continue reading High-speed holography of cells spots physical beacons of disease
