Researchers fabricate high-quality transparent ceramic

Posted by in categories: biotech/medical, chemistry

Mid-infrared lasers have been widely used in imaging, detection, diagnostics, environmental monitoring, medicine, industry, defense and others. For mid-infrared laser systems, low phonon energy gain materials are key factors.

Among these mid-infrared materials, Er3+-doped CaF2 transparent ceramics are promising candidate materials because of their ultra-low phonon energy as well as excellent physical, chemical, and , which quickly attract the attention of researchers. However, traditional preparation methods can’t obtain high-quality Er3+-doped CaF2 transparent ceramics.

Recently, a research team led by Prof. Zhang Long from the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has developed a high quality Er3+-doped CaF2 transparent ceramics by single crystal ceramization. Their study was published in Journal of the European Ceramic Society.

An Alzheimer’s Drug Has Been Shown to Help Teeth Repair Cavities Naturally

Posted by in categories: biotech/medical, neuroscience

Circa 2018 o,.o!

Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib.

Developed for and trialled to treat Alzheimer’s disease, last year scientists found the drug also happens to promote the natural tooth regrowth mechanism in mice, allowing the tooth to repair cavities.

Northrop Grumman to terminate OmegA rocket program

Posted by in categories: business, security, space

WASHINGTON — Northrop Grumman announced it will not move forward with the development of the OmegA rocket. The vehicle was designed for the sole purpose of competing for a National Security Space Launch contract award but didn’t make the cut.

“We have chosen not to continue development of the OmegA launch system at this time,” Northrop Grumman spokeswoman Jennifer Bowman said in a statement. “We look forward to continuing to play a key role in National Security Space Launch missions and leveraging our OmegA investments in other activities across our business.”

Bowman said the company will not be protesting the U.S. Space Force’s decision to select United Launch Alliance and SpaceX for the NSSL contracts.

The Most Common Pain Relief Drug in The World Induces Risky Behaviour, Study Suggests

Posted by in category: biotech/medical

One of the most consumed drugs in the US – and the most commonly taken analgesic worldwide – could be doing a lot more than simply taking the edge off your headache, new evidence suggests.

Acetaminophen, also known as paracetamol and sold widely under the brand names Tylenol and Panadol, also increases risk-taking, according to a new study that measured changes in people’s behaviour when under the influence of the common over-the-counter medication.

“Acetaminophen seems to make people feel less negative emotion when they consider risky activities – they just don’t feel as scared,” says neuroscientist Baldwin Way from The Ohio State University.

Massive Magellanic Cloud Halo Discovery Finally Explains Stream of Gas Swirling Around the Milky Way

Posted by in category: space

The Milky Way is not alone in its neighborhood. It has captured smaller galaxies in its orbit, and the two largest are known as the Small and Large Magellanic Clouds, visible as twin dusty smears in the Southern Hemisphere.

As the Magellanic Clouds began circling the Milky Way billions of years ago, an enormous stream of gas known as the Magellanic Stream was ripped from them. The stream now stretches across more than half of the night sky. But astronomers have been at a loss to explain how the stream became as massive at it is, over a billion times the mass of the sun.

Pentagon warns that China’s Naval power is growing

Posted by in category: military

The Chinese Navy is already the largest in the world, with a fleet of more than 350 ships that includes a fast-growing armada of destroyers, carriers and submarines, a reality which continues to raise concerns with the Pentagon and Navy weapons developers. By the end of this decade, China is expected to operate as many as 400 ships, according to the Pentagon’s 2020 China Military Power report which catalogs the pace and extent of China’s ambitious military modernization. “China is the top ship-producing nation in the world by tonnage and is increasing its shipbuilding capacity and capability for all naval classes,” the report said.

39% of The World’s Rich Would Take a Space Flight – But Then What?

Posted by in categories: finance, space travel

The modern space race is getting closer to making astronauts out of tourists – and a new survey finds that there is already pent-up demand, even as questions linger over the industry.

About 39 per cent of people with a net worth of more than $5 million (Dh18.3m), a total addressable market of about 2.4m, are interested in paying at least $250,000 (the current price) for a Virgin Galactic flight to the edge of space, according to financial services firm Cowen.

These findings come as Virgin Galactic takes another step towards offering commercial space flights, which will one day provide paying customers about six minutes of weightlessness as the spacecraft hurtles through Earth’s atmosphere.
