No, Vaccinated People Are Not 'Just as Likely' to Spread the Coronavirus as Unvaccinated People

Among this last group, a common r

A Ferocious Asteroid Strike Demolished an Ancient Middle Eastern City 3,600 Years Ago
As the inhabitants of an ancient Middle Eastern city now called Tall el-Hammam went about their daily business one day about 3,600 years ago, they had no idea an unseen icy space rock was speeding toward them at about 38,000 mph (61,000 kph).

Metals supercharge a promising method to bury harmful carbon dioxide under the sea
There's a global race to reduce the amount of harmful gases in our atmosphere to slow down the pace of climate change, and one way to do that is through carbon capture and sequestration—sucking carbon out of the air and burying it. At this point, however, we're capturing only a fraction of the carbon needed to make any kind of dent in climate change.

Micro-scale opto-thermo-mechanical actuation in the dry adhesive regime
Realizing optical manipulation of micro-objects in nonliquid environments is challenging due to strong friction force (~µN) that makes optical force (~pN) insignificant. Towards this goal, scientists from Westlake University in China demonstrated spiral motions of microscopic objects on dry surfaces as driven by nanosecond laser pulses. They revealed the underlying mechanism relating to interactio

Non-native fish are main consumers of salmon in reservoirs
When warmwater fish species like bass, walleye and crappie that are not native to the Pacific Northwest, but prized by some anglers, overlap with baby spring chinook salmon in reservoirs in Oregon's Willamette River they consume more baby salmon than native fish per individual, new research found.

Continental growth is not a continuous process
The continents, a specific feature of our planet, still hold many secrets. Using chemical data on sedimentary rocks compiled from the scientific literature from the 1980s to the present day, researchers have uncovered a new geological history of the continents. The research shows that their growth was not a continuous process, and that they have always been rich in silica1. This new study calls in

Deadly virus's pathway to infect cells identified
Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hundreds of human cases and dozens of deaths.

Using transparent ink to print color images
A team of researchers affiliated with a host of institutions in China has developed a new way to print color images using standard inkjet printers. In their paper published in the journal Science Advances, the group describes how they used a type of clear ink to produces dome-shaped microstructures on a glass plate that together render a color image.

0 Kelvin is absolute zero. So based on that, it is proposed that the complete net-zero standard is called a Kelvin.
Had this idea in a different thread.. The ideal is total net-zero. Net zero emissions of greenhouse gases, energy, waste and water usage. So a Kelvin building or facility would be one that achieved certification in all four areas. A Kelvin organization or agency would be one where all their properties achieved that status. What else, if anything, should be added to the list? Is zero emissions inc

A speculative crisis that could be bad in the future.
This is highly speculative and may be total BS. But I think there should be some consideration about these issues. I've put some thought into them but I've not done much research nor am I an expert. So take what I say with a grain of salt. There's a growing trend of derealization in the fast changing modern world. Coupled with a lack of purpose, this may cause stimulation seeking behaviors.

Medfött immunsvar kan förutsäga hur sjuka vi blir i covid-19
Egenskaperna hos en viss typ av vita blodkroppar (granulocyter) i det medfödda immunförsvaret verkar påverka hur sjuka vi blir i covid-19. Genom att kombinera analyser av dessa celler med välkända biomarkörer i blodet kan man förutsäga svårighetsgraden av sjukdomen. Granulocyter är en familj av vita blodkroppar som består av neutrofila, eosinofila och basofila granulocyter. De ingår i det så kall

Laser Cap Therapy Helps You Regrow Hair From the Comfort of Home
It's estimated that 85-percent of men and 40-percent of women experience visible hair loss by the time they turn 50. However, it doesn't have to be that way. For decades, a high tech treatment called low light laser therapy has been helping people reverse the signs of hair loss. And now, thanks to products like the Kiierr Laser Cap , this treatment is easier to perform and more affordable than ev

Improving gender diversity in leadership by 'opting-out' of the default
Much of the discourse surrounding the lack of women in leadership revolves around their personality traits. Yet, numerous studies have shown that programs aimed at making women push themselves forward for leadership roles has a limited effectiveness in improving gender diversity. So, what can organizations do to address the gender gap? A new study in Leadership Quarterly shows that the answer lies

Volunteer observations during pandemic lockdown showed many bird species increasing in abundance in urban areas
A team of researchers from several institutions in Canada and one in the U.S. has found that the numbers of some birds in urban areas increased during last year's pandemic lockdown. In their paper published in the journal Science Advances, the group describes how they used data from eBird, a large biodiversity community science program run by Cornell's Lab of Ornithology, to compare bird numbers i

Fecal contamination in popular Montana backcountry area primarily attributable to wildlife or pack animals
Is increased human visitation to backcountry areas impacting water quality? Investigators analyzed water samples from a suite of backcountry lake outlets in the Absaroka-Beartooth Wilderness Area of Montana for fecal contamination. Combining a traditional fecal bacterial assay and polymerase chain reaction (PCR), researchers found fecal contamination, but in most cases the source does not appear t

In response to the COVID-19 pandemic, many cities are joining the trend towards providing more space for pedestrians. The current health crisis has put the spotlight on how we use public spaces and some towns and cities have extended pedestrian zones in order to facilitate social distancing and prevent contagion. Some roads have also been closed to traffic, but there was formerly no scientific met

It can also generate 3D images and calculate depth of field by measuring the amount of time it takes for a photon to tr

Ancient beads are the earliest sign of communication with fashion
Researchers have found shell beads in a cave in Morocco that are at least 142,000 years old. The researchers say they're the earliest known evidence of humans communicating about themselves through their attire. The find also sheds new light on how humans' cognitive abilities and social interactions evolved. "They were probably part of the way people expressed their identity with their clothing,"
