US: Arkansas carries out first of its planned executions

Canadian researchers are developing a DNA vaccine for SARS-CoV-2, the coronavirus that causes COVID-19 and has currently infected nearly 5,00,000 people worldwide and crippled the global economy.

Entos Pharmaceuticals, a health-care biotechnology company headed by a University of Alberta researchers, develop new therapeutic compounds using the company's proprietary drug-delivery platform and has begun manufacturing vaccine candidates against the novel coronavirus.

"Given the urgency of the situation, we can have a lead candidate vaccine within two months. Once we have that it's a race to get it into clinical trials," said John Lewis, CEO of Entos and a Professor at the University of Alberta in Canada.

Lewis said in comparison to a traditional vaccine, DNA-based vaccines hold several advantages.

Nucleic acids are introduced directly into the patient's own cells, causing them to make pieces of the virus--tricking the immune system into mounting a response without the full virus actually being present, the researcher said.

According to the company, the approach is recognised as being easier to move into large-scale manufacturing, offers improved vaccine stability and works without needing an infectious agent.

In the current absence of a vaccine for COVID-19, several companies around the world are mounting efforts to begin similar work.

The first clinical trial using a DNA-based vaccine developed by Moderna Inc.in the US on March 13.

Their approach allows for antibodies to be made in the human trial volunteers against a specific protein on the surface of the coronavirus that lets the virus enter human cells.

The hope is that the antibodies will stop the interaction.

Though this approach is designed to be effective against COVID-19 specifically, Lewis said Entos is taking a different tack.

The company plans to use plasmid DNA to amplify the production of key coronavirus surface and structural proteins with each injection, with an eye to the bigger picture.

"Many of the structural proteins in the virus are pretty well conserved across all the coronaviruses, including SARS and MERS," said Lewis.

"We're hoping that if we express more of the structural proteins that are common to most coronaviruses, we can inhibit the current COVID-19, and also potentially protect against all coronaviruses both past and future," Lewis added.

To move the project forward quickly, the company is seeking financial support from both provincial and federal levels of government.

"We have the opportunity to save a lot of lives, and I think it's really upon us and governments to find solutions for that," Lewis said.

Kabul, Jan 27: A passenger plane crashed on Monday in a Taliban-held area of Afghanistan's Ghazni province, local officials said.

Arif Noori, spokesman for the provincial governor, said the plane went down around 1:10 p.m. local time in Deh Yak district, which is held by the Taliban. Two provincial council members also confirmed the crash.

The number of people on board and their fate was not immediately known, nor was the cause of the crash.

Ariana Airlines, Afghanistan's national carrier, dismissed the claim that one of their planes had crashed in a statement on their website, saying all their aircraft were operational and safe.

The mountainous Ghazni province sits in the foothills of the Hindu Kush mountains and is bitterly cold in winter.

The last major commercial air crash in Afghanistan occurred in 2005 when a Kam Air flight from western Herat to the capital Kabul crashed into the mountains as it tried to land in snowy weather.

The war however has seen a number of deadly crashes of military aircraft. One of the most spectacular occurred in 2013 when an American Boeing 747 cargo jet crashed shortly after takeoff from Bagram air base north of Kabul en route to Dubai in the United Arab Emirates. All seven crew member were killed.

Afghanistan's aviation industry suffered desperately during the rule of the Taliban when its only airline Ariana was subject to punishing sanctions and allowed to fly only to Saudi Arabia for Hajj flights.

Since the overthrow of the religious regime smaller private airlines have emerged but the industry is still a nascent one.

Jun 15: Oil prices fell on Monday, with U.S. oil dropping more than 2%, as a spike in new coronavirus cases in the United States raised concerns over a second wave of the virus which would weigh on the pace of fuel demand recovery.

Brent crude futures fell 66 cents, or 1.7%, at $38.07 a barrel as of 0016 GMT, while U.S. West Texas Intermediate (WTI) crude futures fell 81 cents, or 2.2%, to $35.45 a barrel.

Both benchmarks ended down about 8% last week, their first weekly declines since April, hit by the U.S. coronavirus concerns: More than 25,000 new cases were reported on Saturday alone as more states, including Florida and Texas, reported record new infection highs.

"Concerns about the recent uptick in COVID-19 infections in the U.S. and a potential 'second wave' are weighing on oil at the moment," said Stephen Innes, chief global market strategist at AxiCorp.

Meanwhile, an OPEC-led monitoring panel will meet on Thursday to discuss ongoing record production cuts to see whether countries have delivered their share of the reductions, but will not make any decision, according to five OPEC+ sources.

The Organization of the Petroleum Exporting Countries (OPEC) and its allies, collectively known as OPEC+, have been reducing supplies by 9.7 million barrels per day (bpd), about 10% of pre-pandemic demand, and agreed in early June to extend the cuts for a month until end-July.

Iraq, one of the laggards in complying with the curbs, agreed with its major oil companies to cut crude production further in June, Iraqi officials working at the fields told Reuters on Sunday.
