Transportable radio telescopes could provide global high-precision comparisons of the best atomic clocks. — ScienceDaily

Using radio telescopes observing distant stars, scientists have connected optical atomic clocks on different continents. The results were published in the scientific journal Nature Physics by an international collaboration between 33 astronomers and clock experts at the National Institute of Information and Communications Technology (NICT, Japan), the Istituto Nazionale di Ricerca Metrologica (INRIM, Italy), the Istituto Nazionale di Astrofisica (INAF, Italy), and the Bureau International des Poids et Mesures (BIPM, France).

The BIPM in Sèvres near Paris routinely calculates the international time recommended for civil use (UTC, Coordinated Universal Time) from the comparison of atomic clocks via satellite communications. However, the satellite connections that are essential to maintaining a synchronized global time have not kept up with the development of new atomic clocks: optical clocks that use lasers interacting with ultracold atoms to give a very refined ticking. “To take the full benefit of optical clocks in UTC, it is

Better detection of microwave radiation will improve thermal imaging, electronic warfare, radio communications — ScienceDaily

Army-funded research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will enable improved thermal imaging, electronic warfare, radio communications and radar.

Researchers published their study in the peer-reviewed journal Nature. The team includes scientists from Harvard University, The Institute of Photonic Sciences, Massachusetts Institute of Technology, Pohang University of Science and Technology, and Raytheon BBN Technologies. The Army, in part, funded the work to fabricate this bolometer by exploiting the giant thermal response of graphene to microwave radiation.

“The microwave bolometer developed under this project is so sensitive that it is capable of detecting a single microwave photon, which is the smallest amount of energy in nature,” said Dr. Joe Qiu, program manager for solid-state electronics and electromagnetics, Army Research Office, an element of the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory.

Is Radio Taking Advantage of New Technology

For the radio industry staying on top of technological changes that impact how consumers take in audio is vital. The old fashioned radio is being replaced by smart speakers and mobile devices and as Edison Research reported yesterday that trend continues.

Edison’s latest research continues to highlight radio’s hardware problem, especially with the younger audiences. Eleven formats were indexed against the market average for owning a traditional radio receiver in their home. Formats whose P1 listeners are more likely to own an in-home radio include Classic Hits, Classic Rock, Country, Hard Rock/Heavy Metal, News/Talk, and Sports. Formats less likely to own an in-home radio include Alternative Rock, Contemporary Christian, and the two formats that index the lowest for in-home radio ownership: Hip Hop/Rap and Top 40. R&B is exactly the market average for owning a radio in the household.
The good news for radio, if the

  • The following is a preview of the US Digital Audio Ad Spending 2020.

During the pandemic and ensuing lockdowns, fewer people commuted to work every day, and many local businesses cut their marketing budgets as they fought to stay open. These conditions have strained the radio advertising market.

US radio ad spending is expected to decline by 25% this year.

eMarketer


In our March 2020 forecast, US radio ad spending was expected to decline just 1.0%. We now anticipate a 25.0% drop. Ad spending declines in traditional channels are part of a long-standing trend, but the pandemic further deepened the decrease in radio ad spending.

We expect radio ad spending to partially rebound next year, rising 16.8% to $12.18 billion. But that will be

Why We’re Scared of Invisible Radio Waves

This article originally appeared on VICE France.

The 5G rollout has been far from smooth. Despite its dazzling promises, like the advent of self-driving cars and virtual reality, the fifth generation of mobile internet is considered a threat by many. On the 14th of July of this year, the UK banned 5G kits produced by Chinese manufacturer Huawei due to security concerns. Meanwhile, activists are taking issue with the environmental cost of the new technology, which will require enormous resources just to replace the already-speedy 4G network.

Then, there’s a group of people who oppose 5G because they believe it’s a health hazard. The theory that mobile phones cause cancer has been around for a while, albeit with little scientific basis. In its latest iteration, conspiracy theorists say 5G phone towers are weakening our immune systems and increasing our vulnerability to COVID-19. Some even believe the towers transmit the
