The population of corals within Australia’s Great Barrier Reef has plummeted by 50 percent in the last two decades, according to a new study published on Wednesday.
Researchers from the ARC Centre of Excellence for Coral Reef Studies in Queensland, Australia, assessed the colony size of corals in the reef — the world’s largest — between 1995 and 2017, and found a drastic depletion in the population of small, medium and large coral.
“The decline occurred in both shallow and deeper water, and across virtually all species, but especially in branching and table-shaped corals,” study co-author Professor Terry Hughes said of the findings, published in the Royal Society journal.
These specific corals are especially important in providing a habitat for marine life such as fish that inhabit the reef, the researchers said, meaning their loss also results in a decline in reef biodiversity. Despite covering less than 0.1 percent of
WASHINGTON — The Army is using internal development and small-business ideas to figure out how to fire artillery faster, exploring every facet from how projectiles are stored all the way to automated reloading.
Brig. Gen. John Rafferty, who is in charge of Long-Range Precision Fires modernization, told Defense News in an interview ahead of the Association of the U.S. Army’s annual conference that he is “a little bit embarrassed” to describe to innovative small companies how the Army handles ammunition in an artillery battalion, realizing that the process hasn’t changed in over 50 years.
“When you evaluate the amount of time and man hours these soldiers doing these tasks, one-by-one unbanding projectiles and inspecting them one-by-one, inventorying them one-by-one,” Rafferty said. “What if we could automate some of those tasks? And then how much more effective that unit would be in its operational mission, if those soldiers were preparing for
Typically, there’s a bit of a delay between when astronauts launch from Earth to the International Space Station, and when they actually dock with the orbital lab. This has to do with the relative orbits of the launch spacecraft and the ISS, as well as their takeoff point from Earth. Expedition 64, which launched today, however, docked with the station just around three hours after leaving Earth from Baikonur Cosmodrome in Kazakhstan.
The Soyuz spacecraft carrying NASA astronaut Kate Rubins and Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov took off at just before 2 AM EDT, and docked with the ISS at 4:48 AM EDT – three hours and two minutes after liftoff. The hatches between the capsule and the station opened at 7:07 AM EDT, officially beginning the operational duty roster stint for the three new ISS crew members. Coincidentally it’s also Rubins’ birthday.
Astronomers from the California Institute of Technology and elsewhere report the detection of a new eclipsing detached double white dwarf binary. The system, designated ZTF J2243+5242 has an orbital period of below 10 minutes, which makes it one of the shortest-period eclipsing binaries known to date. The finding is detailed in a paper published October 7 on arXiv.org.
Astronomers are interested in finding and studying double white dwarfs (DWDs), as their mergers are believed to produce new white dwarfs with higher masses. It is assumed that some high-mass white dwarfs in the solar neighborhood could be DWD merger products.
The Zwicky Transient Facility (ZTF), using the Palomar Observatory in California, is one of the most important astronomical surveys to search for double white dwarf binary systems. So

NASA released the Artemis Accords in May to establish a framework of principles for safely and responsibly planning for humanity’s return to the moon.
“Artemis will be the broadest and most diverse international human space exploration program in history, and the Artemis Accords are the vehicle that will establish this singular global coalition,” said NASA Administrator Jim Bridenstine in a statement.
“With today’s signing, we are uniting with our partners to explore the Moon and are establishing vital principles that will create a safe, peaceful, and prosperous future in space for all of humanity to enjoy.”
Global ecolabel registry extends coverage, enabling identification of environmentally-preferable PV
World’s First EPEAT-Rated Photovoltaic Solar Module
The Series 6 photovoltaic (PV) module, designed and manufactured by U.S.-headquartered First Solar, Inc., is the world’s first PV product to be rated in the Electronic Products Environmental Assessment Tool (EPEAT) registry for sustainable electronics.
PORTLAND, Ore. and TEMPE, Ariz., Oct. 14, 2020 (GLOBE NEWSWIRE) — The Green Electronics Council (GEC) today announced that the Series 6 photovoltaic (PV) module, designed and manufactured by U.S.-headquartered First Solar, Inc. (Nasdaq: FSLR), is the world’s first PV product to be included in the launch of the EPEAT Photovoltaic and Inverters product category.

London, October 14, 2020 – Avenir LNG Limited (NOTC:AVENIR) today announced that its subsidiary Avenir (L) Pte. Ltd. has taken delivery of its first dual purpose liquefied natural gas bunkering and supply vessel (LBV) Avenir Advantage from Keppel Offshore & Marine, at the Nantong Shipyard, Jiangsu Province, China.
Following her maiden voyage, Avenir Advantage will commence a three-year charter to Petronas LNG Sdn Bhd in Malaysia; becoming the first dedicated LBV in South East Asia. She will supply LNG to fuel ships operating in the region and deliver LNG directly to Petronas small-scale customers.
Milorad Doljanin, CEO Avenir LNG Limited, commented: “With the delivery of the Avenir Advantage, we move one step closer to delivering our shareholders’ vision of creating a small-scale LNG supply and marketing portfolio.”
“The flexible design of our vessels allows us to support
MOSCOW (AP) — A trio of space travelers launched successfully to the International Space Station, for the first time using a fast-track maneuver to reach the orbiting outpost in just three hours.
NASA’s Kate Rubins along with Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos lifted off as scheduled Wednesday morning from the Russia-leased Baikonur space launch facility in Kazakhstan for a six-month stint on the station.
Oct. 13 (UPI) — Blue Origin successfully launched a NASA moon landing experiment aboard the company’s reusable New Shepard rocket Tuesday morning in Texas.
Liftoff took place from the company’s launch facilities about 150 miles east of El Paso.
The capsule separated from the rocket minutes into the flight and spent about 3 minutes at the height of an arc just over the Kármán line, the altitude at which space begins.
The rocket booster, with NASA sensors mounted on the exterior, landed smoothly about 7 minutes, 30 seconds after launch. The capsule landed with the aid of parachutes a few minutes later, kicking up a cloud of dust and sand.
The NASA experiment is part of the agency’s Tipping Point program, which seeks to demonstrate technology that can be adopted by private industry.
The project includes a collection of sensors designed to help locate a safe site on the moon
