San Diego Zoo Vaccinates 9 Great Apes for COVID-19

The San Diego Zoo has vaccinated nine great apes for the coronavirus after a troop of gorillas in its Safari Park became infected. Officials said Thursday four orangutans and five bonobos received COVID-19 injections in January and February. Three bonobos and a gorilla also are expected to recei


Strict environmental laws 'push' firms to pollute elsewhere

Multinational companies headquartered in countries with tougher environmental policies tend to locate their polluting factories in countries with more lax regulations, a new study finds.   While countries may hope their regulations will reduce emissions of carbon dioxide and other green


Greenland ice loss may have begun as early as the mid-'80s

The amount of snow falling on Greenland's glaciers may have been less than the water lost through icebergs calving and melting since at least the mid-1980s, a study of almost 40 years of satellite images has revealed.   The study was undertaken by Dominik Fahrner, a Ph.D. student with t


Rare earth unlocks copper, gold and silver secrets

A study by Monash scientists has found that a rare earth affects the fate of a key reaction with copper, gold, silver, and uranium mineralisation.   The work is part of the "Olympic Dam in a test tube" project, where researchers tried to reproduce the processes that resulted in the conc


NASA's new Mars rover hits dusty red road, 1st trip 21 feet

NASA's newest Mars rover hit the dusty red road this week, putting 21 feet on the odometer in its first test drive.   The Perseverance rover ventured from its landing position Thursday, two weeks after setting down on the red planet to seek signs of past life. The roundabout, bac


Israel's turtles treated with mayonnaise after oil spill

After being swept up in the worst environmental disaster to hit Israel’s coastline in years, turtles had the tar cleaned off their shells and are recovering with a diet of mayonnaise. “They are two years old and they’re full of tar and they can’t breathe, and they can


SpaceX Starship rocket explodes after completing successful landing

  A SpaceX rocket exploded after what seemed to be a successful launch and landing during a test flight in Boca Chica, Texas, on Wednesday. The Starship prototype, called SN10, performed a high-altitude flight test before coming back to Earth. As the spacecraft, positioned horizontally


World’s oldest known wild bird hatches new chick at age 70

The world’s oldest known wild bird – a Laysan albatross named Wisdom – not only turned 70 this year, but has also reared what is at least her 40th chick, in a feat which is stretching the boundaries of human knowledge of how birds live. Wisdom, who was banded in 1956, is the old


NASA's James Webb Space Telescope completes final functional tests to prepare for launch

February marked significant progress for NASA's James Webb Space Telescope, which completed its final functional performance tests at Northrop Grumman in Redondo Beach, California. Testing teams successfully completed two important milestones that confirmed the observatory's internal electronics a


Energy-related emissions up in December despite pandemic

Global energy-related carbon dioxide emissions rose slightly in December compared with the same month of 2019, indicating the sharp drop seen due to the pandemic was short-lived.   Figures released Tuesday by the International Energy Agency show emissions from the production and use of


How a plant regulates its growth

Plants grow towards the light. This phenomenon, which already fascinated Charles Darwin, has been observed by everyone who owns houseplants. Thus, the plant ensures that it can make the best use of light to photosynthesize and synthesize sugars. Similarly, the roots grow into the soil to ensure th


Apollo rock samples capture key moments in the Moon's early history, study find

Volcanic rock samples collected during NASA's Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moon's iron core, as well as the crystallization of the lunar magma ocean—the sea of mol


New study suggests supermassive black holes could form from dark matter

A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving 'normal' matter, supermassive black holes could instead form directly from dark matter i


Dogs Came to N. America With Earliest Humans: Study

Scientists said Wednesday they had discovered the oldest remains of a domestic dog in the Americas dating back more than 10,000 years, suggesting the animals accompanied the first waves of human settlers. Humans are thought to have migrated to North America from Siberia over what is today the Ber


Triumph the koala climbs and runs with prosthetic foot made by Australian dentist

Triumph, a male koala born without a foot, has been climbing and running since he was fitted with a prosthetic one made by a neighbourhood dentist, an Australian wildlife carer said on Monday. Veterinarian nurse Marley Christian had rescued the joey koala in northern New South Wales in 2017, afte


Population of Mexico's monarch butterflies falls 26%, conservationists find

The population of monarch butterflies that arrived in Mexico’s forests to hibernate this winter fell 26% from a year earlier, the country’s Commission for National Protected Areas and the World Wildlife Fund (WWF) said on Thursday. Millions of orange and black monarch butterflies migr


The GRANTECAN discovers the largest cluster of galaxies known in the early universe

A study, led by researchers at the Instituto de Astrofísica de Canarias (IAC) and carried out with OSIRIS, an instrument on the Gran Telescopio Canarias (GTC), has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this struc


US military tests space-based solar power device

Scientists at the Pentagon tested a prototype solar device that could one day allow energy harvested in space to be beamed back to Earth. The device, called the Photovoltaic Radio-frequency Antenna Module (Pram), was sent from the Pentagon’s X-37B drone, a reusable unmanned spacec
