Move Over Lasers, It’s Maser Time

No, masers are not just a word that we came up with just now dota 2 다운로드. They’ve actually been around since the 1950s, before lasers were invented. The problem is that they’ve always been impractical–that is, until the team of researchers came up with a device that could let masers over take lasers in the coolness race 다운로드.

They have yet to determine what the maser can do, but like the laser the discoveries only happen when you shoot stuff.

The expectation is that the more precise maser can shoot through clouds (lasers can’t), detect extra-terrestrials, and turn into a surgical tool that can exactly attack a tumor wget 디렉토리.

From the August cover of Nature magazine:

The maser is the microwave-frequency precursor of the now ubiquitous laser verdana 폰트. But it has had little technological impact compared with the laser, in large part because of inconvenience: masers typically require vacuum and/or low-temperature operating conditions 다운로드.

Some researchers think they’ve solved that problem and have published a paper in Nature magazine, Room-temperature solid-state maser 다운로드.

Why is Dentistry so out of date?

Brushing, flossing, white strips and mouthwash: Thanks for all the help, but your services may no longer be required. The end of the cavity could be upon us 플레이 스토어 앱 다운로드.

UCLA microbiologist Dr. Wenyuan Shi has developed a mouthwash that completely eliminates the most malevolent of the 1,000 species of bacteria that can live in your mouth—after just one use 다운로드. In a clinical study, 12 subjects who rinsed just one time with the mouthwash experienced a nearly complete elimination of the baleful bacteria, Streptococcus mutans 다운로드. Four days after the first rinse, their mouths remained mutans-free.

Shi’s mouthwash is currently being tested by the FDA . If the mouthwash passes that hurdle, it will be the first cavity fighter approved since fluoride 60 years ago 다운로드.

“I actually had no dental training,” Shi recalls, laughing. But once he began teaching, he was struck by how, in a country where we can reduce the risk of heart attacks and diabetes, battle cancer and lower cholesterol, dentistry remained out of date 다운로드. The scientist-scholar resolved to work toward converting dentistry from a surgical model to a medical model.

“Last year in American health spending, heart disease was No 한국영화 무료 다운로드. 1, cancer was No. 2 and dentistry was No. 3,” Shi notes. “We spent about $100 billion. In part, because it’s so old-fashioned. Mechanical removal is still the primary tool.”
