New hope for stroke patients as scientists find way to restore mobility and touch using human stem cells to recreate nerve connections in damaged rat brain…

Scientists have found a way to restore mobility and touch in rats after a stroke using human stem cells to recreate nerve connections in damaged brains — offering patients a new hope.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the infectious disease COVID-19, which was first reported in Wuhan, China in December, 2019. Despite the tremendous efforts to control the disease, COVID-19 has now spread to over 100 countries and caused a global pandemic. SARS-CoV-2 is thought to have originated in bats; however, the intermediate animal sources of the virus are completely unknown. Here, we investigated the susceptibility of ferrets and animals in close contact with humans to SARS-CoV-2. We found that SARS-CoV-2 replicates poorly in dogs, pigs, chickens, and ducks, but ferrets and cats are permissive to infection. We found experimentally that cats are susceptible to airborne infection. Our study provides important insights into the animal models for SARS-CoV-2 and animal management for COVID-19 control.

In late December 2019, an unusual pneumonia emerged in humans in Wuhan, China, and rapidly spread internationally, raising global public health concerns. The causative pathogen was identified as a novel coronavirus (1–16) that was named Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) on the basis of a phylogenetic analysis of related coronaviruses by the Coronavirus Study Group of the International Committee on Virus Taxonomy (17); the disease it causes was subsequently designated COVID-19 by the World Health Organization (WHO). Despite tremendous efforts to control the COVID-19 outbreak, the disease is still spreading. As of March 11, 2020, SARS-CoV-2 infections have been reported in more than 100 countries, and 118,326 human cases have been confirmed, with 4,292 fatalities (18). COVID-19 has now been announced as a pandemic by WHO.

Although SARS-CoV-96.2% identity at the nucleotide level with the coronavirus RaTG13, which was detected in horseshoe bats (Rhinolophus spp) in Yunnan province in 2013 (3), it has not previously been detected in humans or other animals. The emerging situation raises many urgent questions. Could the widely disseminated viruses transmit to other animal species, which then become reservoirs of infection? The SARS-CoV-2 infection has a wide clinical spectrum in humans, from mild infection to death, but how does the virus behave in other animals? As efforts are made for vaccine and antiviral drug development, which animal(s) can be used most precisely to model the efficacy of such control measures in humans? To address these questions, we evaluated the susceptibility of different model laboratory animals, as well as companion and domestic animals to SARS-CoV-2.

With data from NASA’s LRO mission, researchers have recreated what the Apollo 13 astronauts saw on their trip around the moon.

Last year, a global collaboration of scientists made history by unveiling the very first direct image of a black hole. Now, we have a magnificent follow-up — the closest-ever look at a violent jet spewed forth by a supermassive black hole.

Perhaps one day we will transcend our biological limitations and be more like mutants or aliens?

The group of patients received the anti-viral drug remdesivir as part of a compassionate use’’ trial, not a double-blind placebo-controlled trial which would offer more definitive evidence.

Fresh air, sunlight and improvised face masks seemed to work a century ago; and they might help us now.

By Richard Hobday

When new, virulent diseases emerge, such SARS and Covid-19, the race begins to find new vaccines and treatments for those affected. As the current crisis unfolds, governments are enforcing quarantine and isolation, and public gatherings are being discouraged. Health officials took the same approach 100 years ago, when influenza was spreading around the world. The results were mixed. But records from the 1918 pandemic suggest one technique for dealing with influenza — little-known today — was effective. Some hard-won experience from the greatest pandemic in recorded history could help us in the weeks and months ahead.

DARPA is planning to develop a travel adapter for the human body. Called the ADvanced Acclimation and Protection Tool for Environmental Readiness (ADAPTER), the new program aims to produce an implantable or ingestible bioelectronic device to help soldiers handle jet lag and diarrhea.

Anyone who has traveled extensively knows that jet lag and diarrhea are not jokes. Jet lag and other sleep-cycle disruptions such as shift work can impair alertness and athletic performance, and cause disorientation, fatigue, indigestion, irritability, insomnia, and excessive sleepiness. Meanwhile, travel diarrhea can produce symptoms that range from unpleasant to severe.

This is bad enough for tourists or business people, but for soldiers jet lag and diarrhea can be a real hindrance as hundreds or even thousands of soldiers can be deployed to the other side of the world at a moment’s notice, only to end up running so far ahead of the logistical chain that they have to rely on local food and water instead of standard military rations. The end result is soldiers impaired by disrupted sleep cycles or requiring medical attention for intestinal problems as a result of consuming contaminated food and water.

At Samsung, we have a long tradition of supporting the health and vitality of our communities. Our company and our employees have generously given to schools, charitable causes and local institutions to address hometown needs across the United States. Our philosophy is simple – our business and employees thrive when our partners and communities thrive.

With nearly 20,000 employees spread across the U.S., our top priority remains to keep them and their families healthy and safe during this unprecedented time. This extends to the communities in which they call home.

Since the onset of COVID-19, we have worked to supply Samsung products and technology to aid frontline healthcare workers in local hospitals across New York and New Jersey. To assist school systems with their transition to remote learning, we have built on the 10 years of our Solve for Tomorrow program by expediting the delivery of nearly $3 million in technology and supplies to local schools across the country. We continue to support consumers with round-the-clock care at Samsung.com and have extended our product warranties for those impacted by COVID-19.
