Physicists weigh in on the origin of heavy elements

Posted by in categories: cosmology, physics

A long-held mystery in the field of nuclear physics is why the universe is composed of the specific materials we see around us. In other words, why is it made of “this” stuff and not other stuff?

Specifically of interest are the responsible for producing heavy elements—like gold, platinum and uranium—that are thought to happen during neutron star mergers and explosive stellar events.

Scientists from the U.S. Department of Energy’s (DOE) Argonne National Laboratory led an international nuclear physics experiment conducted at CERN, the European Organization for Nuclear Research, that utilizes novel techniques developed at Argonne to study the nature and origin of heavy elements in the universe. The study may provide critical insights into the processes that work together to create the exotic , and it will inform models of stellar events and the early universe.

Turbulent Gas Clouds and Respiratory Pathogen Emissions: Potential Implications for Reducing Transmission of COVID-19

Posted by in category: biotech/medical

The coronavirus can travel up to 23–27 feet :


This JAMA Insights Clinical Update discusses the need to better understand the dynamics of respiratory disease transmission by better characterizing transmission routes, the role of patient physiology in shaping them, and best approaches for source control in the context of the COVID-19 outbreak.

One world government needed to cope with COVID-19, says former British PM

Posted by in categories: biotech/medical, government

The Guardian reported that Brown would have liked the U.N. Security Council to have been invited to an emergency online meeting of the G20 countries today. The meeting, hosted by Saudi Arabia, is tackling the issue of the novel coronavirus.

“This is not something that can be dealt with in one country,” Brown said.

“There has to be a coordinated global response.”

Getting Closer to a Blood Test for Alzheimer’s Disease?

Posted by in categories: biotech/medical, neuroscience

As research on Alzheimer’s disease (AD) advances, a desperate need remains for an easy blood test to help diagnose the condition as early as possible. Ideally, such a test could also distinguish AD from other forms of dementia that produce similar symptoms. As published recently in Nature Medicine, an NIH-funded research team has designed a simple blood test that is on course to meet these criteria [1].

The latest work builds on a large body of work showing that one secret to predicting a person’s cognitive decline and treatment response in AD lies in a protein called tau. Using the powerful, but expensive, approach of PET scan imaging, we know that tau builds up in the brain as Alzheimer’s disease progresses. We also know that some tau spills from the brain into the bloodstream.

The trouble is that the circulating tau protein breaks down far too quickly for a blood test to offer a reliable measure of what’s happening in a person’s brain. A few years ago, researchers discovered a possible solution: test for blood levels of a slightly different and more stable version of the protein called pTau181 [2]. (The “p” in its name comes from the addition of phosphorus in a particular part of the protein’s structure.)

Maker Mask launches in Seattle using 3D-printing technology to produce protective gear

Posted by in categories: 3D printing, biotech/medical, engineering, finance, government, health

The 19 3D-printable parts that make up the mask are visible on the Maker Mask website along with details on materials needed, download instructions, videos, the ability to donate to the cause and more. The cost of each finished mask, printed in about three hours, is estimated to be between $2 and $3.


A technology veteran and a 3D-printing “savant” have teamed with other members of industry, health care and government to launch Maker Mask, a Seattle nonprofit creating medically endorsed, reusable protective masks using everyday 3D printers.

Universal cancer blood test detects and locates 50 types of tumors

Posted by in categories: biotech/medical, robotics/AI

Cancer is one of humanity’s leading killers, and the main reason for that is it’s often hard to detect until it’s too late. But that might be about to change. Researchers have developed a new type of AI-powered blood test that can accurately detect over 50 different types of cancer and even identify where it is in the body.

There are just so many types of cancer that it’s virtually impossible to keep an eye out for all of them through routine tests. Instead, the disease usually isn’t detected until doctors begin specifically looking for it, after a patient experiences symptoms. And in many cases, by then it can be too late.

Ideally, there would be a routine test patients can undergo that would flag any type of cancer that may be budding in the body, giving treatment the best shot of being successful. And that’s just what the new study is working towards.

Two more astronauts join SpaceX’s first crewed mission to the ISS

Posted by in category: space travel

Two more astronauts have been assigned to the first operational crewed flight of SpaceX’s Crew Dragon on a mission to the International Space Station (ISS). NASA astronaut Shannon Walker and Noguchi Soichi, of the Japanese Aerospace Exploration Agency (JAXA), will join NASA astronauts Michael Hopkins and Victor Glover Jr., who were assigned to the mission in 2018. If all goes according to plan, this will be the first in a series of regular Crew Dragon flights to the ISS, NASA said in a press release.
