Stem cell treatment offers new hope for diabetics

by Sara HUSSEIN TOKYO, Japan (AFP) — A new method to create insulin-producing pancreatic cells from stem cells and protect them from the body’s immune system could pave the way for improving experimental diabetes treatment. In type-1 diabetes, the body turns on itself and attacks the so-called beta cells inside clusters in the pancreas called “islets”. These beta cells are responsible for gauging sugar levels in the blood and releasing insulin to keep them stable. […]

‘Test-&-trace’ crucial but won’t beat coronavirus alone: study

by Marlowe HOOD PARIS, France (AFP) — Testing for COVID-19 and tracing the prior contacts of those found to be infected are crucial measures for slowing the disease’s spread, but inadequate unless combined with other measures, researchers said Wednesday. By itself, the test-and-trace approach can reduce the virus’ reproduction rate, or R number, by 26 percent, they reported in The Lancet Infectious Diseases, using mathematical models to examine data from previously published studies. The reproduction […]

Pre-orders of COVID-19 vaccine top five billion

by Ivan Couronne WASHINGTON, United States (AFP) — Although none of the coronavirus vaccines under development has proved its efficacy yet in clinical trials, at least 5.7 billion doses have been pre-ordered around the world. First shipments of a COVID-19 vaccine created by Western laboratories have often been snapped up by the United States. Five vaccines — three Western and two Chinese — are in Phase 3 efficacy trials involving thousands of people. In a […]

Mauritius struggles to contain oil spill polluting its seas

Asymptomatic coronavirus carriers have high viral loads: study

WASHINGTON, United States (AFP) — People who are infected with the coronavirus carry similar levels of the pathogen in their nose, throat and lungs whether they have symptoms or not, a new study from South Korea showed Thursday. The paper, published in JAMA Internal Medicine, is an important biological line of evidence in support of the idea that asymptomatic carriers can spread COVID-19. Until now, experts have relied on inferring asymptomatic spread when people contract […]

Defying virus, Latvian ocean rower plans next adventure

by Imants LIEPINSH Agence France-Presse RIGA, Latvia (AFP) — After spending 140 days rowing across the ocean without seeing another human being, Latvian adventurer Karlis Bardelis has some valuable tips for those learning to cope with coronavirus lockdowns.

Along the way, he was rammed by sharks off Papua […]

US announces clinical trial of antibody treatment for COVID-19

  WASHINGTON, United States (AFP) — The US has begun late stage clinical trials into a drug formulated to fight COVID-19, officials said Tuesday. The medicine is an antibody against the new coronavirus called LY-CoV555, which was identified in the blood sample of a recovered patient by Canada’s Abcellera Biologics. It was then developed synthetically for mass production by US-based Lilly Research Laboratories in partnership with Abcellera. The Phase 3 trial will initially enroll some […]

WHO warns there may never be a COVID-19 ‘silver bullet’

  by Robin MILLARD Agence France Presse GENEVA, Switzerland (AFP) — The World Health Organization warned Monday that there might never be a “silver bullet” for the new coronavirus, despite the rush to discover effective vaccines. The WHO urged governments and citizens to focus on doing the known basics, such as testing, contact tracing, maintaining physical distance and wearing a mask in order to suppress the pandemic, which has upended normal life around the globe […]

Plague to protein: Israeli firm seeks to put locusts on the menu

by Jonah MANDEL Agence France-Presse GOLAN HEIGHTS, Undefined (AFP) — From biblical plague to modern day protein, one Israeli firm wants to make locusts a sustainable food choice in the Holy Land and beyond. As for whether or not the insects are kosher, the answer is not so simple. At Hargol Foodtech’s farm in the Israeli-occupied Golan Heights, a rectangular enclosure that once served as a chicken coop is filled with thousands of locusts, a […]

Brazilian Amazon fires surge in July

by Joshua Howat Berger Agence France-Presse RIO DE JANEIRO, Brazil (AFP) — The number of forest fires in the Brazilian Amazon last month rose 28 percent from July 2019, satellite data showed Saturday, fueling fears the world’s biggest rainforest will again be devastated by fires this year. Brazil’s national space agency, INPE, identified 6,803 fires in the Amazon region in July 2020, up from 5,318 the year before. The figure is all the more troubling […]

Russia vows ‘promising’ virus vaccines in September

  MOSCOW, Russia (AFP) — Russia said Wednesday that it plans to begin production of two “promising” coronavirus vaccines in September and October as Moscow races to develop a formula before Western countries. At a meeting chaired by President Vladimir Putin, Deputy Prime Minister Tatyana Golikova singled out two vaccines under development by a research institute in Moscow and a lab in Siberia. “Today there are two vaccines that are the most promising,” Golikova said.

Moderna’s COVID-19 vaccine worked well in monkeys: study

  WASHINGTON, United States (AFP) — US biotech firm Moderna’s COVID-19 vaccine induced a robust immune response and prevented the coronavirus from replicating in the noses and lungs of monkeys, a study in the New England Journal of Medicine said Tuesday. The fact that the vaccine prevented the virus from replicating in the nose is seen as particularly crucial in preventing it from being transmitted onward to others. The same outcome did not occur when […]
