Scientists design ‘sunflower’ city to boost solar energy in countries with relatively low levels of sunlight

Posted by in categories: engineering, solar power, sustainability

Inspired by the distribution of sunflower seeds, a group of scientists say they have developed a new city-pattern that ensures the best distribution of solar energy utilization “in low solar radiation countries.”

“Our new city-plan bears close resemblance to the distribution of seeds in sunflowers. This distribution ensures the best utilization of solar ,” says Dr. Ammar A. T. Alkhalidi, University of Sharjah’s Associate Professor of Sustainable and Renewable Energy Engineering.

Dr. Alkhalidi is the lead author of a new study titled “Sunflower-inspired urban city pattern to improve solar energy utilization in low solar radiation countries.” The study is published in journal Renewable Energy Focus.

Check out these cool Earth images from latest moon mission

Intuitive Machines said its team programmed the lander’s wide and narrow field-of-view cameras “to take five quick images every five minutes for two hours, starting 100 seconds after separating from SpaceX’s second stage,” adding that “out of all the images collected, Intuitive Machines chose to show humanity’s place in the universe with four wonderful images we hope [will] inspire the next generation of risk-takers.”

In a mission update, Intuitive Machines said that Odysseus “continues to be in excellent health” as mission IM-1 makes its way toward the moon for a touchdown scheduled to take place on Thursday. “Flight controllers are preparing planned trajectory correction maneuvers to prepare the lander for lunar orbit insertion,” the company added in its message.

If Intuitive Machines manages to perform a successful soft landing with Odysseus, it will become the first private company to achieve the feat. It will also mark the first soft lunar landing by a U.S. spacecraft since the final Apollo mission in 1972.

Billions Start Flowing to Chip Makers for New U.S. Factories

Posted by in categories: computing, government

The U.S. government is giving chip maker GlobalFoundries $1.5 billion in grants to build and expand facilities in New York and Vermont, the first major award in a program that aims to reinvigorate domestic chip production.

The award from the Commerce Department kicks off what is expected to be a series of cash injections into semiconductor manufacturing projects in Arizona, Texas, New York and Ohio in the coming weeks. Chip makers Intel, Taiwan Semiconductor Manufacturing, Samsung Electronics and Micron Technology have all submitted applications for the government to cover a portion of the billions of dollars it costs to build cutting-edge factories.

Quasar with black hole at its center may be brightest object in the universe, astronomers say

Posted by in category: cosmology

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day.

The record-breaking quasar shines 500 trillion times brighter than our sun. The black hole powering this distant quasar is more than 17 billion times more immense than our sun, an Australian-led team reported Monday in the journal Nature Astronomy.

While the quasar resembles a mere dot in images, scientists envision a ferocious place.

Chemists produce all eight possible variants of polypropionate building blocks from one starting material

Posted by in categories: biotech/medical, chemistry

To synthesize potential drugs or natural products, you need natural substances in specific mirror-image variants and with a high degree of purity. For the first time, chemists at the University of Bonn have succeeded in producing all eight possible variants of polypropionate building blocks from a single starting material in a relatively straightforward process. Their work has now been published in Angewandte Chemie International Edition.

Polypropionates are that can help save lives. They are needed to make reserve antibiotics, compounds that are only ever used to treat infections caused by drug-resistant bacteria. In nature, chiral compounds exist in two different variants that share the same molecular formula but are of each other, like a right and a left hand. Chemists call this “chirality,” which literally means “handedness.”

“What’s interesting is that the mirror-image forms can have very different properties,” explains Professor Andreas Gansäuer from the Kekulé Institute of Organic Chemistry and Biochemistry at the University of Bonn. “One well known example is undoubtedly carvone. The dextro-, or ‘right-handed,’ form of this molecule smells of caraway, while its levo-, or ‘left-handed,’ form is what gives peppermint its distinctive odor.”
