Geologists identify deep-earth structures that may signal hidden metal lodes
Scientists have discovered previously unrecognized structural lines 100 miles or more down in the earth that appear to signal the locations of giant deposits of copper, lead, zinc and other vital metals lying close enough to the surface to be mined, but too far down to be found using current exploration methods.

Spider silk can create lenses useful for biological imaging
Spider silk is useful for a variety of biomedical applications: It exhibits mechanical properties superior to synthetic fibers for tissue engineering, and it is not toxic or harmful to living cells. One unexpected application for spider silk is its use in the creation of biocompatible lenses for biological imaging applications. Researchers now describe the feasibility of creating lenses capitalizing on the properties of natural spider silk material.

For those who don't know (or belong to a newer generation), Microsoft's IE (Internet Explorer) was one browser that had almost monopolized itself globally for many years mostly during the early nineties decade. They managed to do it but the backlash was such that the public pressure practically caused a storm that made Bill Gates sit in front of the jury and answer some hard questions. And today, I'm seeing history is repeating all over again, only Chrome has taken IE's place but there is no storm coming this time. Unlike our predecessors, we are giving in to convenience, we are acting like its not a botheration at all. PLEASE DON'T DO IT . Consider the sheer browser market share that Chrome enjoys and Google's data interests for a moment, and it might already be too late for us. If a web service insists only on Chrome for best performance then change that service, not your browser! If Youtube gives issues to you then use Vimeo or Lbry instead. Let's unite in this effort and take it seriously, let's bring more diversity to the browser world.

Unexpected mental illnesses found in a spectrum of a rare genetic disorder
Researchers found an unexpected spectrum of mental illnesses in patients with a rare gene mutation. These patients had a ''double hit'' condition that combined features and symptoms of fragile X syndrome and premutation disorder, in addition to a range of psychiatric symptoms. The findings revealed the need for clinicians to consider the complexities of the co-existing conditions of patients with both psychological and fragile X associated disorders.

Air pollution major risk for cardiovascular disease regardless of country income
From low-income countries to high-income countries, long-term exposure to fine particulate outdoor air pollution is a major contributor to cardiovascular disease and death, a new study found. But even small reductions in air pollution levels can result in a reduction of disease risk.

Bedtime media use linked to less sleep in children who struggle to self-regulate behavior
Researchers followed 547 children for a week and measured their media use and sleep patterns. For children who generally struggle to self-regulate their behavior, screen time in the hour before bed was associated with less sleep. Media use in children who scored high on measures of effortful control was not related to less sleep.

Coronavirus Death Rate In US 50 Times Higher Than Flu

Keith Birmingham/MediaNews Group/Pasadena Star-News via Getty Images Although the flu and coronavirus have some overlapping symptoms, the coronavirus' death rate in the US is far higher. On average in the US, the flu's death rate is .1%, while the coronavirus' death rate is 4.9%. Both viruses are most deadly for the elderly. The flu kills .83% of infected people above age 65, whereas the the coronavirus's death rate is 10.7% for infected people from age 65 to 74, 21.2% for the 75-84 group, and 30.2% for people over 85.
