UC San Diego research lab to make environmentally friendly flip flops from algae
Researchers at University of California, San Diego hope to make future beach visits both environmentally and fashion-friendly, with a new formula for biodegradable flip flops. Mike Burkart, professor of chemistry and biochemistry at the public research university in San Diego, California, has developed a polymer from algae, which decomposes naturally.
British fossil hunters find bones of new dinosaur species, cousin to T.Rex
Four bones found on a beach on the Isle of Wight, off England’s south coast, belong to a new species of theropod dinosaur, the group that includes Tyrannosaurus rex, researchers at the University of Southampton said on Wednesday. The new dinosaur, which has been named Vectaerovenator inopinatus, lived in the Cretaceous period 115 million years ago and was estimated to have been up to four metres long, the palaeontologists said.
Mystery of the dimming of massive star Betelgeuse explained
Astronomers have determined the cause of the dramatic dimming observed last year and earlier this year of one of the brightest stars in the night sky, a colossus called Betelgeuse that appears to be on its way toward a violent death. Based on Hubble Space Telescope observations, scientists said they believe Betelgeuse ejected a huge hot, dense cloud of material into space that cooled to form dust, shielding the star’s light and making it appear dimmer from the perspective of viewers on Earth.
‘Secret’ life of sharks: Study reveals their surprising social networks
Sharks have more complex social lives than previously known, as shown by a study finding that gray reef sharks in the Pacific Ocean cultivate surprising social networks with one another and develop bonds that can endure for years. The research focused on the social behavior of 41 reef sharks around the Palmyra Atoll, about 1,000 miles (1,600 km) southwest of Hawaii, using acoustic transmitters to track them and camera tags to gain greater clarity into their interactions.
Chemical signal for locust swarming identified in step toward curbing plagues
Scientists have identified a chemical compound released by locusts that causes them to swarm, opening the door to possible new ways to prevent these insects from devouring crops vital to human sustenance as they have for millennia. Researchers said on Wednesday they identified the pheromone – a chemical produced by an animal that affects the behavior of others of its own species – in the world’s most widespread locust species, the migratory locust, or Locusta migratoria.

The idea is very simple. The sun is covered with sunspots, powered by an innate nuclear generator that burns at millions of degrees. These, in turn, are distinguished by massive explosions over the size of the Earth, i.e. solar flares.

It is intuitively understandable that the hottest things in the solar system swirl and experience extreme responses to a changing magnetic field.

Northern municipalities put support behind satellite internet service – ElliotLakeToday.com
The Federation of Northern Ontario Municipalities (FONOM) has cast its attention skyward in joining other Northern Ontario stakeholders calling for better access to high-speed internet.
At its recent board meeting, the municipal advocacy group passed a resolution indicating its support for Starlink, a satellite internet service being developed by SpaceX, the company founded by U.S.-based innovator Elon Musk.
“We know today our citizens require greater connectivity than 50/10 megabits per second,” said FONOM president Danny Whalen in a Sept. 16 news release.
“FONOM believes that the Starlink program is our best option.”
According to a report released by Blue Sky Net earlier this year, the average download speed of participants in a study of northern internet users was just below 9 megabits per second (Mbps) and the average upload speed was just above 5 Mbps.
But for the average user that relies on fast internet speeds for business, education and more, download speeds of 50 Mbps and upload speeds of 10 Mbps are required as the bare minimum to participate in those activities.
In 2018, the federal government’s Canadian Radio-television and Telecommunications Commission (CRTC) set a new target to have 90 per cent of Canadian households with services that deliver download speeds of 50 Mbps and upload speeds of 10 Mbps by 2021. But that goal is still far from being achieved.
Starlink is aiming to deliver high-speed broadband internet, via satellite, to locations where access has been unreliable, expensive, or completely unavailable.
It’s targetting the northern U.S. and Canada for its initial release in 2020, and has plans to reach “near global coverage” in 2021.
The FONOM resolution calls on the CRTC to provide Starlink with a basic international telecommunications licence, which would allow the company to conduct international telecommunications activities.
FONOM said it would also seek support from its partners for the Starlink program.
FONOM, which represents 100 communities in northeastern Ontario, works to better municipal government in Northern Ontario and improve legislation respecting local government in the North.
Venus is a Russian planet — say the Russians – CTV News
This week, Dmitry Rogozin, head of the Russian space corporation Roscosmos, revealed that the country plans to send its own mission to Venus in addition to “Venera-D,” the planned joint mission with the US, the Russian state news agency TASS reported.
Rogozin was addressing reporters at the HeliRussia 2020 exhibition, an international expo of the helicopter industry in Moscow.
“Resuming Venus exploration is on our agenda,” he told reporters Tuesday.
“We think that Venus is a Russian planet, so we shouldn’t lag behind,” he said.
“Projects of Venus missions are included in the united government program of Russia’s space exploration for 2021-2030.”
The statement came the day after scientists revealed that a gas on Earth called phosphine had also been detected in the atmosphere of Venus.
Venus is similar in size to Earth and is our closest planetary neighbour, but it spins backward compared to other planets.
The study authored by Cardiff University professor Jane Greaves and her colleagues was published Monday in the journal Nature Astronomy.
The discovery of phosphine on Venus elevates it to an area of interest worth exploring in our solar system alongside the ranks of Mars and “water world” moons like Enceladus and Europa, Seager said.
“Our hoped-for impact in the planetary science community is to stimulate more research on Venus itself, research on the possibilities of life in Venus’ atmosphere, and even space missions focused to find signs of life or even life itself in the Venusian atmosphere,” Seager said.
According to the European Space Agency, the Russians do have significant experience when it comes to Venus.
Its website states: “Between 1967-1984 Venusian studies carried out in Russia were at the forefront of international research into this planet.
“Since then, Russia has still preserved its unique expertise in designing and developing landing craft for Venus and continues to define scientific tasks for those craft.”
