Workers who are in frequent contact with potentially sick animals are at high risk of bird flu infection. Costfoto/NurPhoto via Getty ImagesRon Barrett, Macalester College Disease forecasts are like weather forecasts: We cannot predict the finer details of a particular outbreak or a particular storm, but we can often identify when these threats are emerging and prepare accordingly. The viruses that cause avian influenza are potential threats to global health. Recent animal outbreaks from a subtype called H5N1 have been especially troubling to scientists. Although human infections from H5N1 have been relatively rare, there have been a little more than 900 known cases globally since 2003 – nearly 50% of these cases have been fatal – a mortality rate about 20 times higher than that of the 1918 flu pandemic. If the worst of these rare infections ever became common among people, the results could be devastating. Approaching potential disease threats from an anthropological perspective, my colleagues and I recently published a book called “Emerging Infections: Three Epidemiological Transitions from Prehistory to the Present” to examine the ways human behaviors have shaped the evolution of infectious diseases, beginning with their first major emergence in the Neolithic period and continuing for 10,000 years to the present day. Viewed from this deep time perspective, it becomes evident that H5N1 is displaying a common pattern of stepwise invasion from animal to human populations. Like many emerging viruses, H5N1 is making incremental evolutionary changes that could allow it to transmit between people. The periods between these evolutionary steps present opportunities to slow this process and possibly avert a global disaster.
Spillover and viral chatter
When a disease-causing pathogen such as a flu virus is already adapted to infect a particular animal species, it may eventually evolve the ability to infect a new species, such as humans, through a process called spillover. Spillover is a tricky enterprise. To be successful, the pathogen must have the right set of molecular “keys” compatible with the host’s molecular “locks” so it can break in and out of host cells and hijack their replication machinery. Because these locks often vary between species, the pathogen may have to try many different keys before it can infect an entirely new host species. For instance, the keys a virus successfully uses to infect chickens and ducks may not work on cattle and humans. And because new keys can be made only through random mutation, the odds of obtaining all the right ones are very slim. Given these evolutionary challenges, it is not surprising that pathogens often get stuck partway into the spillover process. A new variant of the pathogen might be transmissible from an animal only to a person who is either more susceptible due to preexisting illness or more likely to be infected because of extended exposure to the pathogen. Even then, the pathogen might not be able to break out of its human host and transmit to another person. This is the current situation with H5N1. For the past year, there have been many animal outbreaks in a variety of wild and domestic animals, especially among birds and cattle. But there have also been a small number of human cases, most of which have occurred among poultry and dairy workers who worked closely with large numbers of infected animals.Pathogen transmission can be modeled in three stages. In Stage 1, the pathogen can be transmitted only between nonhuman animals. In stage 2, the pathogen can also be transmitted to humans, but it is not yet adapted for human-to-human transmission. In Stage 3, the pathogen is fully capable of human-to-human transmission.Ron Barrett, CC BY-SA Epidemiologists call this situation viral chatter: when human infections occur only in small, sporadic outbreaks that appear like the chattering signals of coded radio communications – tiny bursts of unclear information that may add up to a very ominous message. In the case of viral chatter, the message would be a human pandemic. Sporadic, individual cases of H5N1 among people suggest that human-to-human transmission may likely occur at some point. But even so, no one knows how long or how many steps it would take for this to happen. Influenza viruses evolve rapidly. This is partly because two or more flu varieties can infect the same host simultaneously, allowing them to reshuffle their genetic material with one another to produce entirely new varieties.Genetic reshuffling – aka antigenic shift – between a highly pathogenic strain of avian influenza and a strain of human influenza could create a new strain that’s even more infectious among people.Eunsun Yoo/Biomolecules & Therapeutics, CC BY-NC These reshuffling events are more likely to occur when there is a diverse range of host species. So it is particularly concerning that H5N1 is known to have infected at least 450 different animal species. It may not be long before the viral chatter gives way to larger human epidemics.
Reshaping the trajectory
The good news is that people can take basic measures to slow down the evolution of H5N1 and potentially reduce the lethality of avian influenza should it ever become a common human infection. But governments and businesses will need to act. People can start by taking better care of food animals. The total weight of the world’s poultry is greater than all wild bird species combined. So it is not surprising that the geography of most H5N1 outbreaks track more closely with large-scale housing and international transfers of live poultry than with the nesting and migration patterns of wild aquatic birds. Reducing these agricultural practices could help curb the evolution and spread of H5N1.Large-scale commercial transport of domesticated animals is associated with the evolution and spread of new influenza varieties.ben/Flickr, CC BY-SA People can also take better care of themselves. At the individual level, most people can vaccinate against the common, seasonal influenza viruses that circulate every year. At first glance this practice may not seem connected to the emergence of avian influenza. But in addition to preventing seasonal illness, vaccination against common human varieties of the virus will reduce the odds of it mixing with avian varieties and giving them the traits they need for human-to-human transmission. At the population level, societies can work together to improve nutrition and sanitation in the world’s poorest populations. History has shown that better nutrition increases overall resistance to new infections, and better sanitation reduces how much and how often people are exposed to new pathogens. And in today’s interconnected world, the disease problems of any society will eventually spread to every society. For more than 10,000 years, human behaviors have shaped the evolutionary trajectories of infectious diseases. Knowing this, people can reshape these trajectories for the better.Ron Barrett, Professor of Anthropology, Macalester College This article is republished from The Conversation under a Creative Commons license.

Reduce, Reuse, Rejoice: 5 Holiday Hacks for Eco-Friendly Celebrations
Discover 5 simple holiday hacks to reduce waste and celebrate sustainably. Learn how to plan meals, recycle food scraps, give greener gifts, and properly sort holiday waste while saving money this season.
Reduce, Reuse, Rejoice: 5 Holiday Hacks for Eco-Friendly Celebrations
(Family Features) Holiday celebrations bring joy, laughter and lasting memories – but they can also leave behind a sleigh full of waste. From food scraps and empty bottles to wrapping paper and decorations, the season can leave your home full of items that could be reused or recycled. In fact, household waste increases nearly 25% between Thanksgiving and New Year’s Day, according to survey results from the Center for Biological Diversity. That’s a lot of leftovers, garland and glass that could be kept out of landfills. To help you cut down on trash and embrace a joyful, less-waste holiday season, the experts at CalRecycle offer these five holiday hacks to help you save cash and protect the planet.
Plan Meals to Waste Less and Save More
Shop your pantry first to avoid buying what you already have.
Buy only what you need and prepare recipes based on guest count.
Choose local ingredients from sources like farmers markets that minimize packaging.
Send guests home with leftovers in reusable containers or freeze extras for future meals.
Recycle Food Scraps
Not all food can be saved, but it doesn’t have to go in the trash.
Compost fruit and vegetable trimmings, eggshells, coffee grounds and plate scrapings. Trashed food makes climate pollution in landfills. Recycle it in your green bin instead.
Most California communities now offer green bin composting. Learn what goes in the green bin by visiting the Curb Your Food Scraps page on RecyclingReimaginedCA.com.
Set out a clearly labeled “food scraps” bin next to your trash, as well as a recycling bin for bottles, cans and other containers so everyone can participate.
Eat, Drink and Be Eco-Friendly
Use reusable plates, cups and utensils instead of disposable options.
Decorate with items you can use year after year or make compostable decor from natural materials.
Collect empty wine, liquor, juice or other California Redemption Value (CRV)-eligible containers and cash them in once the party is over.
Serve water in reusable pitchers or carafes instead of single-use plastic bottles.
Give Greener Gifts
Choose experiences over stuff, like tickets to events, museum or club memberships, registrations for classes or shared adventures.
Wrap gifts in fabric, scarves or reusable tins. Or use recyclable paper without glitter or foil.
Personalize presents with homemade crafts, baked goods or services that reduce packaging.
Prioritize gifts from local and sustainable businesses that are committed to ethical sourcing, minimal packaging and recycled materials.
Sort Holiday Waste the Right Way
After the celebrations, check local recycling rules for how to properly dispose of:
Batteries
Holiday lights
Christmas trees
Drop off CRV-eligible beverage containers, such as wine and spirit containers, at your nearest recycling site for cash back.
Donate unwanted gifts or gently used holiday items to local charities or thrift stores.

Creating trendy ensembles when you just want to stay warm can be a challenge, but this season’s hottest looks make it easy to keep cozy while dressing up or down.
(Family Features) Creating trendy ensembles when you just want to stay warm can be a challenge, but this season’s hottest looks make it easy to keep cozy while dressing up or down. Whether you’re aiming for style for a holiday celebration or planning an evening out to shop and take in the holiday lights, this season’s trends have you covered.
Stylish layers and updates to winter wardrobe staples are two keys to nailing this season’s on-trend looks, according to acclaimed American fashion designer Brandon Maxwell, who is collaborating with Walmart as creative director for Free Assembly and Scoop, the retailer’s exclusive, elevated fashion brands.
“Like many people across the country who live in a small town, Walmart was the destination for everything where I grew up, including holiday fashion,” Maxwell said. “When I first teamed up with Walmart, I was excited to bring the joy of fashion to people across the country. Everyone deserves to enjoy their holidays in clothing they love. This year, we are proud to offer the biggest trends in holiday fashion, from cozy outwear to glamorous party looks.”
Maxwell offers these tips for creating the perfect affordable look, no matter where your plans take you this winter:
Metallic Shine: Metallic sweater sets, like a boxy crewneck and matching mini skirt in a glitzy gold shade, are must-have pieces for the holidays. Wear the show-stopping set with matching gold earrings and platform sandals for a head-turning party look.
Layers of Style: Layer festive multicolor patterns in intarsia knits like this Free Assembly fair isle sweater with a plaid puffer jacket for an easy update to winter closet staples like lightly distressed jeans and booties.
Party Perfect: Sophisticated outerwear pieces like a double-breasted coat add a modern touch to classic holiday party looks. Pair with a berry-hued mini dress, black tights and black boots for a look that stands out. For a bit of edge, choose a faux moto jacket layered over a sequin cami top or metallic sweater to complement a faux leather skirt.
Casual Comfort: This season, menswear is all about intentional layering and looks that prioritize both comfort and style. Update vintage-inspired flannels by layering with a quilted puffer pullover and matching them with wintry prints and cargo joggers for a look that’s casual and put together all at once.
Little Lookers: Fashionable little ones can also get decked out this season. Colorful sparkly girl’s dresses from Scoop perfectly complement matching versions for women, ideal for family photos and mommy-and-me moments that make the season extra special. For a more casual event, fair isle sweater dresses in fun shades like lavender can make a classic look oh-so-now.

The Substitute Teacher Who Wanted Blueprints of Our House
A fifth-grade assignment took a strange turn when a substitute teacher asked students to draw schematics of their homes. What followed — a wildly fictional floor plan and a priceless reaction from my mom — turned into one of my funniest childhood memories.
The Substitute Teacher Who Wanted Blueprints of Our House
Elementary school memories tend to blend together — cafeteria pizza, playground arguments, the eternal struggle of times tables — but every once in a while, something happens that sticks with you for life. For me, that moment came in the fifth grade during a week when our regular teacher was out, and we cycled through substitute teachers like we were testing models for durability. By midweek, in walked a substitute with a mysterious, slightly intense energy — the kind of vibe that suggested he either meditated at dawn or worked a graveyard shift doing something he couldn’t talk about. We settled into our seats, expecting worksheets or quiet reading time. But nope. He had other plans. “Today,” he announced, “we’re going to draw schematics of our houses.” Schematics. Not drawings. Not little houses with smoke coming out of the chimney. Actual blueprint-style schematics. He wanted the layout of our bedrooms, our parents’ rooms, and where the pets slept. Every detail. Now, to be fair, Highlights Magazine did have a feature that month teaching kids how to draw floor plans. So maybe he was just a bit overenthusiastic about cross-curricular learning. Or maybe — and this is my completely rhetorical adult theory — he worked the graveyard shift as a cat burglar gathering intel between heists. Just moonlighting between blueprints. While the rest of the class tried their best to recreate their actual homes, my imagination sprinted in a totally different direction. The house I drew had:
A massive master bedroom with an oversized bathroom for my parents
Separate bedrooms for us kids on the opposite side of the house
A kitchen placed right in the center like a command center
And the dog — the true VIP — had a luxurious two-story doghouse
I had basically created a dream home designed by a 10-year-old watching too much Fantasy Homes by the Yard. Later that day, my mom asked the usual question: “So, what did you guys do today?” “We drew schematics of our house,” I said casually. The look on her face was instant and intense. She wasn’t panicked, but there was definitely a “Why does a substitute teacher need to know the exact layout of my home?” expression happening. Parental instincts activated. But then I showed her my diagram. She stared at it. Blinked. Then sighed with massive relief. “This isn’t our house,” she said. “Nope! I made it up,” I replied proudly. Her shoulders relaxed so much she probably lost five pounds of tension in one instant. If the substitute was secretly planning a heist, my masterpiece of misinformation would have sent him to the wrong house entirely. Looking back, the whole moment feels like a sitcom setup — a mysterious substitute collecting “house schematics,” me creating a completely fictional piece of architecture, and my mom going on a full emotional journey in under 30 seconds. Maybe he was just excited about the Highlights Magazine floor-plan activity. Or maybe — just maybe — he moonlighted in cat burglary. We’ll never know. But if he was, I like to think I threw him completely off the scent.
