Lights on the track are helping runners shatter world records

Advancements in shoe technology have garnered headlines and stirred controversy recently for the way they boost performance. But three vaunted world records have fallen in recent weeks thanks in part to wavelight technology, a system of flashing lights that helps runners keep pace with record times.

There are no plans to use the lights at high-profile events such as the Olympics or world championships, where runners angle more for titles than for records. But the lights have been deployed in a handful of a single-day meets this year at which chasing world records was the primary target, generating buzz among fans, coaches and analysts.

Some appreciate the visual cues when watching on television or a computer. Others worry that the runners are benefiting from an artificial aid that wasn’t available to previous generations.

“If our activity is sport, our business is entertainment,” Sebastian Coe, president of World Athletics, the global

Meteorite Lights up Sky Above Mexico As Hurricane Delta Hits and Earthquakes Strike Country

A fireball was spotted in the night sky above north-eastern Mexico on Tuesday, as Hurricane Delta made landfall in the Yucatán Peninsula and several minor earthquakes struck the country.

The fireball was most visible above the states of Nuevo León, Coahuila and Tamaulipas, which border the U.S., around 10:14 p.m. local time, according to the Global Atmospheric Monitoring Agency—part of Mexico’s Institute of Geological and Atmospheric Research.

Some amazed eyewitnesses—as well as some security cameras, webcams and doorbell camss—managed to capture footage of the fireball as it blazed through the atmosphere.

Cameras in Monterrey—the state capital of Nuevo León—captured images of the fireball briefly illuminating the night sky above the city.

Fireballs are unusually bright meteors—the streaks of light that appear in the sky when small pieces of asteroids or comets enter the Earth’s atmosphere and burn up. If these objects avoid completely disintegrating and manage to reach the ground

Lights, camera, fashion: Chanel show goes ahead as Paris tightens lockdown

Bruno Pavlovsky is in a good mood. It is Monday evening, and the president of Chanel’s fashion division has just received confirmation from the French government that the house’s catwalk show can go ahead the following morning.

The show, staged before 500 masked guests under the glass domes of the Grand Palais on the final day of Paris Fashion Week, had been running against the clock. Earlier on Monday, the French government ordered the closure of all bars and cafés in Paris for two weeks from Tuesday as new coronavirus infections rose to 11,500 daily.

Nevertheless, many fashion houses, including LVMH-owned Louis Vuitton and Dior, have gone ahead with live shows.

“The show is the best way to present the collection,” Pavlovsky insists. The company was forced to cancel its Cruise show in Capri in May, and instead debuted the collection online via video in June. Although it reached an

Quantum computing: Photon startup lights up the future of computers and cryptography

A fast-growing UK startup is quietly making strides in the promising field of quantum photonics. Cambridge-based company Nu Quantum is building devices that can emit and detect quantum particles of light, called single photons. With a freshly secured £2.1 million ($2.71 million) seed investment, these devices could one day underpin sophisticated quantum photonic systems, for applications ranging from quantum communications to quantum computing.

The company is developing high-performance light-emitting and light-detecting components, which operate at the single-photon level and at ambient temperature, and is building a business based on the combination of quantum optics, semiconductor photonics, and information theory, spun out of the University of Cambridge after eight years of research at the Cavendish Laboratory.

“Any quantum photonic system will start with a source of single photons, and end with a detector of single photons,” Carmen Palacios-Berraquero, the CEO of Nu Quantum, tells ZDNet. “These technologies are different things, but

Northern Lights Possible Over U.S. This Week As Strong Geomagnetic Storms Predicted, Say Scientists

Have you ever seen the Northern Lights? If you live in northern U.S. states near the Canadian border then the night skies could play host to the sky phenomenon—also called the aurora borealis—at around midnight local time on Monday and later in the week, too.

In the wake of the Sun “waking-up” there have been reports of strong displays of aurora in the night sky in recent weeks, but so far they’ve been confined to the Arctic Circle.

However, the latest predictions from the NOAA Space Weather Prediction Center (NOAA SWPC) suggest high activity is coming this week that could mean aurora borealis being visible as far south as Oregon.

Whether anyone sees them depends not only on “space weather,” but also on local weather since heavy cloud will preclude any sightings.

Comet Chury in all its glory


ESA/Rosetta/NAVCAM

Auroras, better known to we earthlings as northern or southern lights, aren’t limited to just planets and moons. For the first time, scientists have identified the same phenomenon at a comet.

The discovery comes courtesy of the European Space Agency’s Rosetta mission, which famously landed on the comet 67P/Churyumov-Gerasimenko, also known as Comet Chury, back in 2014. 

On Earth, we get auroras when energetic particles from the solar wind interact with our planet’s magnetosphere. When researchers looked at Chury in the far ultraviolet range of the electromagnetic spectrum, they were able to pick up a similar effect from solar wind electrons striking the cloud of gas, or coma, around the comet’s rocky nucleus.

“The resulting glow is one of a kind,” says Marina Galand of Imperial

Book excerpt: ‘The Smallest Lights in the Universe’

Science, even science about the heavens, is done by people, astronomer Sara Seager reminds us throughout her new memoir, “The Smallest Lights in the Universe” (Crown, 2020).

For Seager, a renowned astronomer and planetary scientist at the Massachusetts Institute of Technology, doing science means searching for another Earth around a distant star. But being human means enduring a difficult childhood, exploring northern Canada, raising two sons, losing her husband to cancer, then falling in love anew. Her grace joining the personal and the scientific begins with the book itself, as you’ll read in the prologue below.

New types of aurora are upending our understanding of polar lights

  • Scientists, amateur aurora-hunters, and a NASA intern have discovered fascinating new types of aurora in recent years.
  • One new type of aurora revealed curls in Earth’s upper atmosphere, and another pointed to a strange magnetic crunch in space.
  • New observations of Jupiter’s aurorae have also raised questions about the nature of these lights.
  • Visit Business Insider’s homepage for more stories.

The colorful lights that dance across polar skies create beautiful displays, but they also reveal mysteries about how planets, space, and the sun interact.

Though humans have been observing the aurora for centuries, scientists are still learning about how it works. Just this year, amateur aurora-hunters discovered a new type of aurora that could come from space particles heating Earth’s upper atmosphere. A NASA intern also revealed a new type of twisting aurora, which led scientists to a mysterious crunch in Earth’s magnetic field.
