| Lab-on-a-chip COVID-19 antibody test could offer rapid, accurate results
Posted: 21 Apr 2020 07:05 AM PDT  COVID-19 antibody testing that’s portable, fast, cheap and highly precise—four attributes that are usually mutually exclusive—could be possible with a microfluidic device invented at the University of Michigan and developed by U-M startup Optofluidic Bioassay. A microfluidic device, or “lab on a chip,” shrinks multiple lab functions onto a single chip just millimeters or centimeters […] |
| Who moves forward in the hiring process?
Posted: 21 Apr 2020 06:53 AM PDT  When hiring managers review job applications, they must make rapid assessments about who they think is a good candidate for a position. But those evaluations are especially critical towards applicants whose employment histories differ from conventional notions of what a “good” job is, according to new research by Stanford sociologist David Pedulla. Pedulla found that applicants […] |
| Pandemics of the Past and Future: A Conversation with Nobelist David Baltimore
Posted: 21 Apr 2020 06:44 AM PDT  Though no two pandemics are the same, each one that occurs has lessons to teach us about the next one. David Baltimore, President Emeritus and Robert Andrews Millikan Professor of Biology, is a virologist who studied HIV during the height of the AIDS pandemic in the 1980s and 1990s. In 1975, Baltimore shared the Nobel Prize […] |
| Ault: Future droughts may ‘eclipse’ those of the past
Posted: 21 Apr 2020 06:43 AM PDT  Carbon dioxide and other greenhouse gases continue to raise the world’s atmospheric temperatures, warm the influential Pacific Ocean – an ignition point to drought – and generally disrupt oceanic hydrology. Given those factors, the forecast for drought around the world looks grim. “Droughts of the future may eclipse those of past centuries in their duration, […] |
| A more holistic way to measure economic fallout from earthquakes
Posted: 20 Apr 2020 06:06 PM PDT  When an earthquake or other natural disaster strikes, government relief agencies, insurers and other responders converge to take stock of fatalities and injuries, and to assess the extent and cost of damage to public infrastructure and personal property. Stanford researchers have developed a way to quantify the economic toll that a major earthquake is likely […] |
| Finding Leukemia’s Weakness Using Genome-Wide CRISPR Technology
Posted: 20 Apr 2020 05:56 PM PDT  UC San Diego researchers used CRISPR technology to carry out a genome-wide screen in leukemia cells to block thousands of genes at once. The tool was used to identify genes that fuel leukemia growth, like those leukemia cells (green) pictured growing within the bone marrow. A team of researchers at University of California San Diego […] |
| Method Speeds Discovery of Viruses to Deliver Brain Gene Edits
Posted: 20 Apr 2020 05:55 PM PDT  Viruses are nature’s Trojan horses: They gain entrance to cells, smuggle in their genetic material, and use the cell’s own machinery to replicate. For decades, scientists have studied how to minimize their deleterious effects and even repurpose these invaders to deliver not their own viral genome, but therapeutics for treating disease and tools for studying […] |
| Police training reduced complaints and use of force against civilians
Posted: 20 Apr 2020 05:53 PM PDT  Procedural justice strategies can help rebuild trust between officers and their communities. A Northwestern University evaluation of a procedural justice training program involving more than 8,000 Chicago Police Department (CPD) officers shows it reduced complaints filed against police by approximately 10%. It also reduced use of force by 6% in the two years following officers’ […] |
| COVID-19 treatment depends upon disease severity
Posted: 20 Apr 2020 05:50 PM PDT  How individuals, and health care professionals, deal with infection from SARS-CoV-2, the virus that causes COVID-19, varies depending on the severity of the infection. While the infection almost always starts with relatively mild, flu-like symptoms that can be treated at home, this can change depending on a number of factors. What follows is a breakdown […] |
| Sleep apnea devices need filter for use in COVID-19, Yale doctor warns
Posted: 20 Apr 2020 05:49 PM PDT  A pair of Yale and Harvard professors have co-designed a circuit device to make machines used by sleep apnea patients safer for use by those infected with the COVID-19 virus. Many people being treated for sleep apnea use small devices known as positive airway pressure (PAP) machines to prevent interruption of breathing during the night. […] |
