Infographic: Which Nations are on Russia’s ‘Unfriendly’ List?

On May 13, 2021, Russian President Vladimir Putin signed into law the List of Unfriendly Nations, which included the United States and the Czech Republic.

On March 5, 2022, as Russia’s military operation in Ukraine progressed, the list was updated to include 45 more nations and jurisdictions. The countries and territories mentioned in the list have imposed or joined the sanctions against Russia.

Video: Disinfection Robot

This autonomous disinfection robot utilises a combination of automatic robot programming, autonomous navigation and obstacle avoidance, sensor-based robot control, and novel drives and structure to achieve effective disinfection within a short period.

Its robot arm brings the UVC light close to the object’s surface while maintaining a proper distance to achieve 99.5% disinfection in just a few seconds, which allows fast disinfection of a large area.

The user-friendly graphical user interface enables a user to select disinfection area based on video images and automatically generate robot trajectories to perform the disinfection operation. The invention was developed by Professor Ning Xi from the Department of Industrial and Manufacturing Systems Engineering, Faculty of Engineering of HKU.

Testing Cultivated Meat in Space

This week, four SpaceX crew members will conduct the first-ever experiments on cultivated meat in space. The historic Axiom-1 mission is the first fully private spaceflight to the International Space Station, and among other experiments, will test the effects of microgravity on the formation of Aleph Farms’ cultured muscle tissue.

Scheduled to launch on April 8, the SpaceX Dragon crew includes Israeli philanthropist Eytan Stibbe, who will reportedly transport Aleph Farmer’s “Lab-on-a-Chip” device aboard the ISS and connect it to the station’s power and monitoring systems, which will be overseen by researchers on Earth. Developed in partnership with SpacePharma, Lab-on-a-Chip is described as a microfluidic device that carries living cells in a nutrient-rich growth medium.

Once onboard the ISS, Aleph researchers hope to discover how a microgravity environment impacts the proliferation and differentiation of bovine cells used in its cultivated steak.

A better cultivation platform

“Understanding processes in such an extreme environment, like space, will allow us to eventually develop an automated, closed-loop system that can produce steaks during long-term space missions. Similar to car manufacturers and Formula One, in space we are developing the most efficient processes under the toughest environments,” says Aleph Farms.

“Extended exploration in space, such as traveling to Mars, is limited by the ability to provide astronauts with quality nutrition,” states an Axiom spokesperson. “Aleph Farms is developing a technology platform for producing cultured beef steaks in a process that consumes a significantly lower portion of the resources needed to raise a whole animal for meat.”

Growing research support

Several days ago, the European Space Agency (ESA) announced a project for exploring the possibility of cultivating meat in space. Agency experts will assess astronaut nutrition and various means of protein production in space, and present a preliminary design for space-based cultured meat production, reports Republic World.

All of this research will likely contribute to the improvement of cultivated meat systems on Earth.

“The processes we are validating in space can then be transferred to our mainstream production on Earth to help us increase efficiencies…Our space program will ultimately help us develop more sustainable and resilient food systems anywhere.”

Walk Any Way to Better Health

Whether you’re taking a leisurely stroll through your neighborhood or a power-walk in the park, the American Heart Association, the world’s leading nonprofit organization focused on heart and brain health for all, says taking part in physical activity is one of the best ways to manage stress, reduce the risk of heart disease and stroke and boost your mood.

Improved technology and the growing popularity of fitness applications, electronic wearables and step counters have made counting steps an easy way to count health benefits, as noted through a growing body of scientific research. A study presented at the American Heart Association’s Epidemiology, Prevention, Lifestyle & Cardiometabolic Health Conference 2021 (EPI), found that

  • Study participants who took more steps in short spurts lived longer, regardless of how many steps they had in longer, uninterrupted bouts. The benefits leveled off at about 4,500 steps a day in short spurts.
  • Compared to no daily steps, each initial increase of 1,000 steps a day was associated with a 28% decrease in death during the follow-up period.
  • A 32% decrease in death was noted in participants who took more than 2,000 steps daily in uninterrupted bouts.

Middle-aged people who walked the most steps-per-day had a 43% lower risk of diabetes and a 31% lower risk of high blood pressure, compared to those with the fewest steps, according to research presented at the Association’s 2020 EPI Conference. For women in the study, each 1,000-step interval resulted in a 13% lower risk of obesity, and those with the highest step count were 61% less likely to have obesity, compared to women who walked the least.

People who took at least 7,000 steps a day had a 50% to 70% lower risk of dying compared with people who took fewer than 7,000 steps a day, according to a study published in September in the journal JAMA Open Network. Researchers found that a higher daily step count (over 10,000 steps) lowered the risk of premature death from any cause among Black and white middle-aged women and men.

“Walking is a great way to improve your health and your mental outlook, and it doesn’t take a lot of expensive sporting equipment to do it. Put on a good pair of shoes and grab a water bottle and you’re ready to go,” said Donna K. Arnett, M.S.P.H., Ph.D., B.S.N., a past president of the American Heart Association (2012-2013) and the dean and a professor in the department of epidemiology of the University of Kentucky College of Public Health in Lexington. “It doesn’t matter how fast or how far you walk, the important thing is to get moving. Counting steps doesn’t have to be part of a structured exercise program. Increasing your everyday activity, like parking slightly further from your destination, doing some extra housework or yardwork and even walking your dog can all add up to more steps and better health.”

The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic activity each week. You can knock that out in just 30 minutes a day, 5 days a week. And every minute of moderate to vigorous activity counts toward your goal.

Arnett points out that walking indoors at home, in a gym or even a mall can be easy ways to get beneficial physical activity. However, research indicates that being outdoors in areas rich with trees, shrubs and grass (i.e., a higher level of greenness) may help reduce the risk of dying from heart disease.

“Unfortunately, many people do not have access to safe walking trails or adequate green space. The American Heart Association continues to advocate for policy changes that make it easier for people to have access to safe places to walk, exercise and play, as well as sustainable transportation options that integrate walking, bicycling and wheelchair use,” Arnett said. “The easier it is for people to engage in physical activity in all aspects of their daily life, the more likely we are to achieve healthier, longer lives for everyone.”

National Walking Day is Wednesday, April 6, 2022. Established by the American Heart Association and celebrated on the first Wednesday in April, National Walking Day is a day take a walk, move, dance…do whatever works to get you moving and help you kick-off a commitment to a lifetime of healthy living.
