Galactic cosmic rays now available for study on Earth, thanks to NASA

Posted by in categories: biological, health, particle physics, space

Every once in a while I have a contentious discussion with someone about traveling to Mars, and the risks involved. One of the hardest risks to describe is the threat from galactic cosmic rays. Here is a short article about a new facility investigating the effects of galactic cosmic rays.

The very important point here is that we are not discussing electromagnetic radiation. These ions have been shown to sometimes penetrate spacecraft and inflict damage on astronauts brains. Earthlings do not have to worry about these as much because we have a magnetosphere that shields us from ions.


To better understand and mitigate the health risks faced by astronauts from exposure to space radiation, we ideally need to be able to test the effects of Galactic Cosmic Rays (GCRs) here on Earth under laboratory conditions. An article publishing on May 19, 2020 in the open access journal PLOS Biology from Lisa Simonsen and colleagues at the NASA Langley Research Center, USA, describes how NASA has developed a ground-based GCR Simulator at the NASA Space Radiation Laboratory (NSRL), located at Brookhaven National Laboratory.

Brazil’s Nurses Are Dying as Covid-19 Overwhelms Hospitals

Posted by in categories: biotech/medical, health

The coronavirus is spreading rapidly throughout Brazil, overwhelming a health care system that is ill prepared to handle a pandemic of this magnitude and proving especially deadly for the medical workers on the front lines.

At least 116 nurses have died in this country of 210 million from Covid-19, according to Brazil’s Federal Nursing Council—the highest toll anywhere. That is more than the 107 nurses who have died in the U.S., where the total death count of people succumbing to the pandemic is about six times more than in Brazil. In Italy, which has about twice as many total deaths as Brazil, 39 nurses have died, according to Italy’s National Federation of Nurses, or Fnopi.

Xi Vows China Will Share Vaccine and Gives WHO Full Backing

Posted by in categories: biotech/medical, government, health

Chinese President Xi Jinping pledged to make any coronavirus vaccine universally available once it’s developed, part of an effort to defuse criticism of his government’s response to a pandemic that has killed more than 315,000 people around the world.

In a speech on Monday to the World Health Assembly, the governing body of the Geneva-based World Health Organization, Xi called for greater international cooperation in fighting the pandemic. He also said China will provide $2 billion over two years to support the fight. Taiwan dropped a request to be included in the gathering after objections from Beijing.

Chinese Official Confirms That China Ordered Labs To Destroy Coronavirus Samples

Posted by in categories: biotech/medical, government, health

A senior Chinese government official confirmed Friday that authorities ordered laboratories to destroy samples of coronavirus in early January.

Secretary of State Mike Pompeo had accused Chinese officials of ordering the samples’ destruction as part of the regime’s cover-up of the coronavirus outbreak in its early stages.

Pompeo said on April 22 that China “censored those who tried to warn the world, it ordered a halt to testing of new samples, and it destroyed existing samples.” He offered more specificity on May 6, stating that China’s National Health Commission [NHC] ordered virus samples destroyed on Jan. 3.

Here Is What’s Behind The AI Revolution

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

“A wealth of information creates a poverty of attention,” said Andy McMurray, co-founder and CIO of Medal, an AI-based software company developing tools for health care, during an interview with Healthcare IT News.

This is especially true in the operating room, where surgery teams at the University of Iowa Hospital have reduced surgical site infection by 74% using DASH Analytics’ high-definition care platform (HDCP). This system observes data from the operation in real time and compares it to a patient’s history and its own infection models. Toward the end of the procedure, it automatically provides the surgeon with recommendations to reduce infection during wound closure. Furthermore, it notes whether the surgeon follows its suggestions or not and compares that to the outcome of the patient. This information is then used to both improve its infection model and improve the surgeon’s own performance in future surgeries.

Advances in AI build off of each other. One breakthrough opens the doors for more possibilities in the future, which in turn leads to even more breakthroughs at an exponential rate. Just as the Industrial Revolution automated back-breaking physical labor, the AI Revolution is poised to automate mind-numbing mental labor. Based on what we’ve seen in the last 10 years alone, we can expect to see this boom very soon.

Obama says epidemic “spiraling out of control”, outlines US action

Posted by in categories: biotech/medical, economics, health, military

US President Barack Obama called the Ebola outbreak in West Africa a threat to global security on Tuesday and broadly expanded the US response by ordering thousands of troops to the region along with an aggressive effort to train health care workers and build treatment centres.
He called on other countries to quickly provide more helpers, supplies and money.
“If the outbreak is not stopped now, we could be looking at hundreds of thousands of people affected, with profound economic, political and security implications for all of us,” Obama declared after briefings at the Centers for Disease Control and Prevention in Atlanta.
Obama acted under pressure from regional leaders and international aid organisations who pleaded for a heightened US role in confronting the deadly virus, especially in the hardest-hit countries of Liberia, Sierra Leone and Guinea.
“In West Africa, Ebola is now an epidemic,” Obama said.
“It’s spiralling out of control, it is getting worse.“
The stepped-up US response includes sending 3,000 troops to the region, including medics and corpsmen for treatment and training, engineers to help build treatment facilities and logistics specialists to assist in patient transportation.
Obama also announced that Major General Darryl Williams, head of US Army Africa, will head a military command centre based in Liberia.
The announcement came the same day the World Health Organisation warned that the number of West African Ebola cases could begin doubling every three weeks and that the crisis could end up costing nearly 1 billion US Dollars to contain.
Nearly 5,000 people have become ill from Ebola in Liberia, Sierra Leone, Guinea, Nigeria and Senegal since it was first recognised in March.
The World Health Organisation says it anticipates the figure could rise to more than 20,000.
Obama described task ahead as “daunting” but said what gives him hope is that “the world knows how to fight this disease.“

In US news and current events today, listen to Pres. Bush urgently stress the importance of being prepared for a pandemic back in 2005. In this clip, Pres. George W. Bush addressed the Nat’l Institutes of Health about having a game plan to fight future pandemics. Pres. Bush was reportedly alarmed after reading a history book about the 1918 flu pandemic where millions had died. Out of that interest came a grand outline for future administrations to follow in response to a global pandemic.

A Potential Universal Flu Vaccine Just Passed an Important Clinical Trial

Posted by in categories: biotech/medical, health

There may be hope yet for a universal flu vaccine — one powerful dose of immunisation that can provide long-lasting protection for multiple influenza strains, all in a single shot.

A discovery like that would be a holy grail for public health, and after more than a decade of careful research, a specific version called FLU-v is now moving into the last rounds of clinical testing.

So far, researchers say the results have been “very encouraging”, and the vaccine has successfully passed phase I and phase II clinical trials. Although trials in these phases are limited to assessing the safety of the vaccine, there’s also evidence it might be effective.

Scientists say doing this type of exercise will make your brain more powerful

Posted by in categories: chemistry, health, neuroscience

According to Li and Spitzer, running on a treadmill, or performing another sustained aerobic exercise—like dancing or kickboxing—on a regular basis might actually enhance motor skill-based learning.

When comparing the brains of mice that exercised versus those who did not, Li and Spitzer found that specific neurons switched their chemical signals (neurotransmitters), after exercising, which led to improved learning for motor skill-specific acquisition.

While physical exercise is proven to promote motor skill learning in normal individuals as well as those with neurological disorders, the mechanism of action is unclear. The study found that that one just week of voluntary wheel running enhances the acquisition of motor skills in normal adult mice. Voluntary being the keyword here.
