RNA interference, a revolutionary discovery first made by UMass scientist Craig Mello and his colleagues, can stop the expression of several genes and ultimately treat genetic conditions. And, it is something that humans can artificially control.
This has led to approved therapies for a variety of liver disorders, and now, scientists’ attention is turning to diseases such as Alzheimer’s and ALS.
Mello won the Nobel Prize for the discovery in 2006, and told Jim Braude in Greater Boston that it could change our lives.
“We are very excited to tackle disorders of the central nervous system,” Mello said. “We can now deliver these molecules very well to the brain.”
He says there’s always more to find out, demonstrated this week by NASA’s new James Webb Telescope which has revealed groundbreaking images of distant galaxies.
“What I love about science is this: the more you discover, the more you explore, the more mysterious things are, right?” Mello said with a smile. “It’s like the pictures from a new telescope – absolutely stunning.”

How should surfaces be cleaned to prevent the spread of COVID-19?
Alcohol at 70-90% can also be used for surface disinfection. See the article : Derek Lewis, president of multicultural operations and equity development at PepsiCo, discusses his company’s diversity initiatives. Surfaces should be cleaned with water and soap or detergent first to remove dirt, followed by disinfection.
How to maintain hand hygiene to prevent the spread of COVID-19? • Wash your hands frequently with soap and water for at least 20 seconds, especially after you are in a public place, or after blowing your nose, coughing, or sneezing.• If soap and water are not available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them dry.• Avoid touching your eyes, nose, and mouth with unwashed hands.• Avoid touching frequently touched surfaces in public places—elevator buttons, doorknobs, handrails, shaking hands with people, etc. Use a tissue or sleeve to cover your hand or fingers if you have to touch something.
How to clean surfaces to reduce the risk of COVID-19?
Clean high-touch surfaces regularly or as needed and once you have visitors in your home. This includes desks, doorknobs, light switches, desks, handles, desks, phones, keyboards, toilets, faucets, and sinks. If someone is sick or tests positive for COVID-19, disinfect frequently touched surfaces.
What surfaces should be cleaned during the COVID-19 pandemic?
Frequently touched surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, countertops, bathroom surfaces, toilets and faucets, touch screen personal devices, personal computer keyboards, and workplaces. See the article : Willie Wilson advertises upcoming food and gas deals for $ 2 million. . surface.
What is the CDC guidelines for cleaning soft surfaces during the COVID-19 pandemic?
Clean the surface using a product containing soap, detergent, or another type of cleaner suitable for use on the surface. Wash items (if possible) according to the manufacturer’s instructions. See the article : New pediatric mental health services are now available to primary care providers throughout the state. Use the warmest appropriate water setting and dry the item completely.
What is a healthy diet during the COVID-19 pandemic?
• Daily, eat a mix of whole grains such as wheat, corn and rice, legumes such as lentils and beans, lots of fresh fruit and vegetables, with some foods from animal sources (eg meat, fish, eggs and dairy).• Choose whole grain foods like unprocessed corn, millet, oats, oats, and brown rice if you can; they are rich in valuable fiber and can help you feel full longer. • For snacks, choose raw vegetables, fresh fruit, and unsalted nuts.
What not to eat during the COVID-19 pandemic? Avoid foods that are high in salt and sugar. Limit the amount of soft drinks and other drinks that are high in sugar. Instead of sweet treats like cakes, cookies and candy, opt for fresh fruit.
Is there a way to improve your immune response to COVID-19?
When it comes to boosting your immune response, getting the COVID vaccine and booster shots, along with other recommended vaccinations, is best. Think of vaccinations as a cheat sheet for your immune system. When a viral invader enters your body, your immune system prepares to fight back.
What are the guidelines for proper nutrition during the COVID-19 quarantine?
For optimal health, it is also important to remember to eat healthy and stay hydrated. WHO recommends drinking water instead of sugary drinks. Limit or avoid alcoholic beverages for adults and strictly avoid it in young people, and pregnant and lactating women, or for other health reasons. Ensure plenty of fruit and vegetables, and limit your intake of salt, sugar, and fat. Prefers whole grains over processed foods. For further guidance on how to eat healthy during self-quarantine, please see Tips on food and nutrition during self-quarantine, prepared by WHO/Europe.
What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
We are still learning about immunity to COVID-19. Most people infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or long-lasting that immune response is, or how it differs for different people. There have also been reports of people being infected with COVID-19 for the second time. Until we better understand COVID-19 immunity, it will be impossible to know how much of the population is immune and how long that immunity lasts, much less make predictions about the future. These challenges should hinder any plan that tries to increase immunity in a population by allowing people to become infected.
What is herd immunity in relation to COVID-19? Herd immunity, also known as ‘population immunity’, is the indirect protection from an infectious disease that occurs when a population is immune either through vaccination or developed immunity through a previous infection. WHO supports achieving ‘herd immunity’ through vaccination, not by allowing disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.
Will COVID-19 vaccines stop the pandemic?
It is very likely that SARS-CoV-2, the virus that causes COVID-19, will continue to circulate and evolve. It is impossible to predict how contagious or severe the new variant of the virus will be. Therefore, it is imperative to achieve and maintain high vaccination coverage in all communities and population groups, at national and international levels. Vaccination remains a key component of the multi-layered approach needed to reduce the impact of SARS-CoV-2.
Is COVID-19 vaccination still necessary, even after getting infected with the virus and recovering?
Evidence is growing that vaccination after infection strengthens protection and further reduces the risk of reinfection. Therefore, COVID-19 vaccination is generally recommended for eligible populations, including those who have recovered from the disease.
Can asymptomatic people transmit COVID-19?
Yes, infected people can transmit the virus both when they have symptoms and when they have no symptoms. This is why it is important that all infected people are identified by testing, isolated, and, depending on the severity of their illness, receive medical care.
How is airborne transmission of COVID-19 different from droplet transmission?
Airborne transmission differs from droplet transmission in that it refers to the presence of microbes in the droplet nuclei, which are generally considered to be particles <5μm in diameter, which can remain in the air for long periods of time and are transmitted to others over longer distances. from 1 m.In the context of COVID-19, airborne transmission is possible in certain circumstances and settings where aerosol-generating procedures or ancillary treatments are performed;
What is meant by airborne transmission? Airborne transmission is defined as the spread of infectious agents caused by the spread of droplet nuclei (aerosols) that remain infectious when suspended in the air over long distances and time.
What is COVID-19 droplet transmission?
When an infected person coughs, sneezes, or talks, droplets or tiny particles called aerosols carry the virus into the air from their nose or mouth. Anyone within 6 feet of the person can inhale it into their lungs.
How does COVID-19 airborne transmission occur?
Air transmission. Research shows that the virus can live in the air for up to 3 hours. It can enter your lungs if someone who has it breathes in and you inhale that air. Experts are divided over how often the virus spreads by air routes and how much it contributes to the pandemic.
