Nutmeg compound effective in suppressing coronavirus infection: Hokkaido Univ.
SAPPORO -- Nutmeg contains a compound capable of suppressing infection by the coronavirus, a research group at Hokkaido University here has discovered.
The finding raises prospects for developing antiviral medications derived from natural sources that are safer than current drugs, which carry the risk of side effects such as liver dysfunction, the research team said.
According to professor Kenji Monde of the Faculty of Advanced Life Science at Hokkaido University Graduate School of Life Science, researchers noted the antiviral properties of malabaricone C, a component found in nutmeg, during research aimed at developing lipid synthesis inhibitors useful in preventing Alzheimer's disease and obesity.
In experiments, malabaricone C was added to cells derived from fetal kidney tissue before exposing them to the coronavirus. The cells treated with malabaricone C apparently showed resistance to infection, with their survival confirmed afterward.
However, researchers cautioned that malabaricone C accounts for a very small proportion of nutmeg's overall composition, at just 0.006%, making it virtually impossible to prevent infections through normal dietary intake. Moreover, excessive consumption of nutmeg can lead to neurotoxicity.
Professor Monde stated, "It's important to accumulate information now, to be prepared for developing new medications should COVID-19 infections spread in the future."
The research was published online in the British scientific journal Scientific Reports.

Canon, Fujifilm face GE HealthCare's growing scope
TOKYO -- U.S.-based GE HealthCare Technologies has expanded its reach in Japan while wielding market-leading computed tomography (CT) scanners as well as diagnostic drugs, pushing local players Canon and Fujifilm Holdings to try to counter its substantially larger scale. GE HealthCare entered the field of surgical treatment with an acquisition in 2021 and was spun off from General Electric in January 2023. The company looks to expand further through the highly profitable diagnostic drug business -- radiopharmaceuticals in particular. Radioactive substances can be used to diagnose cancer and Alzheimer's disease as well as aid in providing treatment tailored to each patient.

British-Japanese chef provides at-home cooking services
By Kathryn Wortley With 41% of expats experiencing digestive health issues, such as weight change, in their new country of residence according to a 2024 survey by financial services company Allianz, nutritionist and personal chef Dan Martin is on a mission to support the health and well-being of the international community in Tokyo, Chiba and Kanagawa. Through his company Sankaku Nutrition, the British-Japanese entrepreneur provides in-home meal preparation services and consultations to busy professionals, drawing on his degree in nutrition from the University of Nottingham, and his time as a chef in England, Austria and Japan. Now Martin is embarking on a new aspect to his business: the creation of an online community united by an interest in nutrition. What inspired you to establish Sankaku Nutrition? I met my wife in Hakuba, Nagano Prefecture. I was working as a chef but I knew there was more to me and wanted to provide my family with something more. I decided Tokyo would be a good place to grow a business and that international residents would be a good target market. Lots of expats find it challenging to eat healthily in their new home, largely due to unfamiliarity with local ingredients and lack of knowledge about how to cook with them, or perhaps due to specific dietary needs. My purpose is to help them and I love what I do. Image: Dan Martin How does your service work? After an inquiry, I start with a discovery call, where the client explains their situation and I'll see if I can meet their needs. If they are happy with the prices, I'll suggest going to visit their home to see if they have the space and equipment I would need for cooking. If they become a customer, on each visit, I prepare about five meals, typically a main and two sides, totaling 20 portions. I do meal planning beforehand — and often grocery shopping — and then cook for about six hours in their home and clean up at the end. What sort of clients do you have? Most are vegetarian. I think it became that way because it's hard to be a vegetarian in Japan. As a child, when I visited my grandmother in rural Gifu Prefecture, that wasn't my experience but in the big cities, I see a lot of emphasis on meat now. Even dishes that would normally be vegetarian tend to have a bit of ground meat or bacon in them. Dashi or consume stock is also often used and it contains fish or chicken. What's the most enjoyable part of your work? Working so closely with people; I become almost a member of the family and I see people thrive. Creating those personal relationships makes the world seem positive. And, unlike in my previous roles as a chef, I get to make and create new recipes and menus every day. I've developed as a recipe creator more than I would have were I working in a restaurant. Image: Dan Martin And the most challenging? It's hard work. If my day includes grocery shopping for customers, I typically walk 7–8 km, and I carry up to 20 kg of supplies and equipment to and from the client's home. But it's not a bad challenge and it keeps me really fit. The most difficult thing is probably balancing everything: my day-to-day work, keeping the business healthy and spending time with my family. Thankfully, I often finish early so I can see my kids. Why is your next step to go online? I'm proud of what I do with my clients and I know it has an impact on them and their children. There is also a butterfly effect — if I help someone in healthcare to work better, they can help more people. But I want to have a bigger reach so I plan to go completely digital within five years. There's also a financial factor; if I can't be physically present at work, I can't make any money, which is a risk as I'm the sole provider to my family. I'd like to create something that doesn't require me to be present all the time. What will you offer? I'm starting a YouTube channel first. The idea is to share simple ways to make healthy meals and explain nutrition in a way that makes sense. When we get a good group or audience going I hope to bring people together into an online communication app or platform, perhaps on Discord. That way, we can figure out together what people really need, whether it's full courses, apps, special programs, or even just recipe books. I'm open to whatever works best to help people out the most. What are your thoughts as you embark on this project? I've already outlined the first few videos and I am working to get everything sorted; there's a lot that goes behind the scenes of making YouTube content that I didn't realize before. As an entrepreneur, you can have an idea of what you want to do but it's not necessarily the best thing. I've got to start moving forward and build on people's reactions. It'll be a big learning curve but social media encourages you to continue improving. Image: Dan Martin © Japan Today

U.S. gov't restores some medical research grants, says top Trump official
NIH Director Jay Bhattacharya is a physician and health economist who left a professorship at Stanford University to join the Trump administration A senior U.S. health official on Tuesday admitted President Donald Trump's administration had gone too far in slashing biomedical research grants worth billions of dollars, and said efforts were underway to restore some of the funding. Jay Bhattacharya, director of the National Institutes of Health (NIH), made the remarks during a Senate committee hearing examining both recent cuts to his agency and deeper reductions proposed by the White House in next year's budget. Bhattachartya said he had created an appeals process for scientists and laboratories whose research was impacted, and that the NIH had already "reversed many" of the cuts. "I didn't take this job to terminate grants," said the physician and health economist who left a professorship at Stanford University to join the Trump administration. "I took this job to make sure that we do the research that advances the health needs of the American people." The hearing came a day after more than 60 NIH employees sent an open letter to Bhattacharya condemning policies they said undermined the agency's mission and the health of Americans. They dubbed it the "Bethesda Declaration" -- a nod both to the NIH's suburban Washington headquarters and to Bhattacharya's role as a prominent signatory of the 2020 "Great Barrington Declaration," which opposed Covid lockdowns. Since Trump's January 20 inauguration, the NIH has terminated 2,100 research grants totaling around $9.5 billion and $2.6 billion in contracts, according to an independent database called Grant Watch. Affected projects include studies on gender, the health effects of global warming, Alzheimer's disease, and cancer. Trump has launched a sweeping overhaul of the US scientific establishment early in his second term -- cutting billions in funding, attacking universities, and overseeing mass layoffs of scientists across federal agencies. © 2025 AFP
