Biden says Trump's USPS funding opposition shows he 'doesn't want an election'

Posted: 13 Aug 2020 12:27 PM PDT

Biden says Trump's USPS funding opposition shows he 'doesn't want an election'Presumptive Democratic presidential nominee Joe Biden is slamming recent comments from President Trump he says prove his opponent doesn't "want an election." Biden spoke Thursday after Trump in a Fox Business interview said he is against the funding for the United States Postal Service that Democrats are pushing for in a stimulus bill, with the president suggesting this is specifically because he wants to prevent universal mail-in voting during the COVID-19 pandemic. "Pure Trump," Biden said of these comments. "He doesn't want an election."The Biden campaign in a statement on Thursday also accused the president of "sabotaging a basic service that hundreds of millions of people rely upon, cutting a critical lifeline for rural economies and for delivery of medicines, because he wants to deprive Americans of their fundamental right to vote safely."In the Fox Business interview, Trump, who has asserted without evidence that increased mail-in voting during the coronavirus crisis would result in widespread voter fraud, had said that without the $25 billion for the USPS that Democrats want and that he is blocking, "you can't have universal mail-in voting, because they're not equipped to have it." > "Pure Trump," Joe Biden says when asked about Pres. Trump's comments on U.S. Postal Service.

U.S. judge dismisses NRA lawsuit challenging gun shop closures in New York stateA federal judge on Friday dismissed the National Rifle Association's lawsuit challenging New York's decision to close gun stores in the state in the early stages of the coronavirus pandemic. The decision came eight days after New York Attorney General Letitia James filed a lawsuit seeking to dissolve the gun rights group, accusing senior leaders of corruption including the improper diversion of millions of dollars. U.S. District Judge Mae D'Agostino said the NRA lacked standing to challenge on behalf of its members a March 20 executive order by Governor Andrew Cuomo requiring gun stores to close in the state because they were "non-essential" businesses.

Close contact with a Covid-19 sufferer brings 20 per cent chance of catching virus, study finds

Posted: 13 Aug 2020 08:34 AM PDT

Close contact with a Covid-19 sufferer brings 20 per cent chance of catching virus, study findsComing into close contact with a Covid-19 sufferer yields a 20 per cent chance of catching the disease, a new study shows. The large-scale survey, by Imperial College London, found antibodies in one in five people who said they had interacted with a positive case. Overall, some 3.4 million people are now estimated to have been infected with coronavirus – about six per cent of the population. The results come from the world's largest home testing programme looking for past evidence of the disease, using fingerprick testing kits. The study tracked the spread of infection across England after the pandemic's first peak, with volunteers testing themselves at home between June 20 and July 13. People living in London were most likely to have been infected, along with those working in care homes and health care, people from black, Asian and minority ethnic groups and people living in larger households. The programme suggested a total of 13 per cent of people living in London had Covid-19 antibodies, compared with less than three per cent in the south-west of England. People working in care homes (16 per cent) and healthcare (12 per cent) returned far higher results than people who were not key workers, at five per cent. The study found that 17 per cent of black volunteers had antibodies, while the categories of Asian and other ethnic minorities had 12 per cent each. The figure among white volunteers was only five per cent. People aged 18-34 showed the highest incidence of antibodies, at eight per cent, while the over-65s had the lowest rate, at just three per cent (the graphic below shows infections by age range during July and August).

Oregon State Police Withdraws from Portland Courthouse after D.A. Announces He Won’t Prosecute Most Rioters

Posted: 14 Aug 2020 05:50 AM PDT

Oregon State Police Withdraws from Portland Courthouse after D.A. Announces He Won't Prosecute Most RiotersOregon state police are backing out of an agreement to protect the Portland federal courthouse from rioters, after the Multnomah County district attorney announced he will not prosecute most rioters who are arrested.Portland has seen riots almost every night since the May death of George Floyd, an African American man killed during his arrest by Minneapolis police officers. Rioters initially targeted the federal courthouse in the city, but after federal and state law enforcement came to an agreement to jointly protect the courthouse, rioters moved on to attack city police.Multnomah County D.A. Mike Schmidt announced on Tuesday that his office would not prosecute most rioters who have been arrested, except where charges include deliberate property damage, theft, or threat of violence. Police have arrested over 500 people since the riots began, but less than 50 have been prosecuted so far.Oregon state police told KOIN 6 on Thursday that they are ending their deployment at Portland's federal courthouse because of anger over Schmidt's decision after being called in to assist as part of the agreement reached between local authorities and the federal government."The Oregon State Police is continually reassessing our resources and the needs of our partner agencies and at this time we are inclined to move those resources back to counties where prosecution of criminal conduct is still a priority," OSP said in a statement.Governor Kate Brown said the withdrawal was being coordinated between all relevant agencies."This transition was made in coordination with local and federal officials," Brown wrote on Twitter. "If further state support is needed in Portland, OSP troopers will be available to return to the city.""The OSP Troopers assigned to this event demonstrated the best traditions of the agency's commitment to service, however, our initial commitment to the City of Portland has concluded and it is time we integrate this valuable resource back to their respective communities," OSP said in a statement to National Review. "OSP will always be here for Portland, as we have for decades and I'll continue to assess subsequent resource demands with the Portland Police Bureau Chief, whom I have a great deal of respect for and a strong working relationship."

The COVID-19 virus can spread through the air – here's what it'll take to detect the airborne particles

Posted: 14 Aug 2020 05:12 AM PDT

The COVID-19 virus can spread through the air – here's what it'll take to detect the airborne particlesA growing body of research shows that SARS-CoV-2, the virus that causes COVID-19, can spread from person to person through the air. Indoor spaces with poor ventilation in areas where the virus is prevalent are particularly hazardous.In the fictional world of "Star Trek," public health officials and first responders would be able to determine instantly if a space had a dangerous concentration of airborne virus, and any other pathogen, by simply waving around a tricorder. That technology, imagined 60 years ago, is still firmly in the realm of fiction. However, devices that can rapidly detect particular airborne pathogens – including SARS-CoV-2 – are in the works in various research laboratories. The air we breatheDetection of the presence of airborne virus particles is complicated by the mixture of other particles in the air. The atmosphere includes a large number of floating particles, a significant fraction of which are biological. Typically, with each breath, you inhale about a thousand biological particles.These bioaerosols include live and dead organisms, including viruses, bacteria, fungi, pollen and plant and animal debris. Viruses are the smallest of these particles. They range in size from 10 to 300 nanometers, or millionths of a millimeter. In contrast, red blood cells average about 6 to 8 microns, or 6,000 to 8,000 nanometers, in diameter. Bacteria range from 1 to 4 microns and fungi 5 to 10 microns. Plant and animal debris is generally larger than 10 microns.Most of these biological particles are not a health concern, because most are bits of plants and animals, including humans. However, it only takes a small number of dangerous microbes to produce a pandemic. IDing bad news microbesTo understand the potential threat from bioaerosols, it's important to identify the small fraction of problematic or pathogenic microbes from among all the bioaerosols present. Bioaerosol identification begins with capturing biological particles from the air, typically by collecting particles on a filter, in a liquid vial or on hydrogels. Often, researchers transfer the collected bioaerosols to a culture medium that is designed to support microbe growth. How the microbes respond to a specific culture medium – the size, shape, color and growth rate of the microbe colony – can indicate the microbe species. This process can take several days to weeks, and is often ineffective. It turns out the scientists can only identify about 1% of airborne microbes with this approach.Increasingly, scientists are relying on gene-based analyses to map viruses and other microorganisms collected in air samples. One popular technique for gene-based analysis is polymerase chain reaction (PCR), which uses an enzymatic reaction to make many copies of a specific gene or portion of a gene so that the genetic sequence – DNA or RNA – can be detected in a sample. A PCR test can be designed to spot gene sequences specific to a microorganism so that detecting the sequence equals identifying the microorganism. This technique is currently the gold-standard for detecting the presence of SARS-CoV-2 from nasal swab samples. PCR-based methods are very accurate in identifying pathogens.Next generation sequencing technology makes it possible to rapidly sequence organisms' whole genomes. Using these techniques, researchers now have the ability to understand the entire population of microorganisms — their diversity and abundance — in the air. Rapid detectionDespite these advances, there is still a lot of work to be done to be able to instantaneously identify the presence of pathogens in air. Current techniques for identifying microbes are expensive, require specialized equipment and involve long processing steps. They also can't detect a species from small amounts of genetic material.Recent advances, however, provide some promise for the development of sensors that can provide quick information about bioaerosols. One approach uses laser induced florescence. In this technique, particles are illuminated with light of a particular color or wavelength, and only biological particles respond by fluorescing, or emitting light. This technique can be used to identify and quantify the presence of biological particles in air in real-time but it doesn't differentiate between a safe and a harmful microbe. Another advance is using mass spectrometry for bioaerosol detection. In this technique, a single bioaerosol particle is blasted apart with a laser and the molecular fragments are immediately analyzed to determine the molecular composition of the particles. Researchers are also using Raman spectroscopy-based sensors. Raman spectroscopy can identify molecular composition from light reflected off of samples without destroying the samples. Big challenge in a small packageThese techniques are advancing instant detection and identification of airborne bacteria and fungi, but they are less efficient in detecting viruses, including SARS-CoV-2. This is primarily because viruses are very small, which makes it difficult to collect them with air samplers and difficult to perform PCR analysis given the small amount of DNA/RNA. Researchers are working to address the limitations of detecting airborne viruses. In our lab at Clarkson University, we have developed a low-cost bioaerosol sensor and collector for wide-scale bioaerosol sampling. This battery-operated sampler uses a micro-sized high-voltage source to ionize airborne viruses, bacteria and fungi and collect them on a surface. Ionization gives the biological particles an electrical charge. Giving the collection surface the opposite charge causes the particles to stick to the surface.Samples from our collector can be analyzed with new portable DNA/RNA sequencers, which allows for near real-time bioaerosol detection with low-cost, hand-held equipment. Where's my tricorder?These advances could soon make it possible to detect a known pathogen, like SARS-CoV-2, with a portable device. But they're still far from being a tricorder. [Deep knowledge, daily. Sign up for The Conversation's newsletter.]For one, they require relatively high levels of a pathogen for detection. Being able to identify a virus like SARS-CoV-2 at lower levels that are nonetheless sufficient for disease transmission will require developing sensors with lower detection limits. Additionally, these sensors can only be tailored to detect specific pathogens, not scan for all possible pathogens.Though the equivalent of the tricorder in "Star Trek" isn't around the corner, the need for such a device has never been greater. Now is an opportune time for the emergence of new sensing techniques piggy-backing on the dramatic advances being made in the fields of electronics, computing and bioinformatics. When the next new pathogen emerges, it would be nice to have a tricorder handy.This article is republished from The Conversation, a nonprofit news site dedicated to sharing ideas from academic experts.Read more: * Rapid home-based coronavirus tests are coming together in research labs — we're working on analyzing spit using advanced CRISPR gene editing techniques * Aerosols are a bigger coronavirus threat than WHO guidelines suggest – here's what you need to knowSuresh Dhaniyala is President, Potsdam Sensors, a startup that is commercializing TracB.
