James Smoliga, a High Point University physiology and sports medicine specialist, has harnessed his expertise in the service of humanity by calculating just how many hot dogs a person could potentially wolf down in 10 minutes. Thank you, Dr. Smoliga.

Smoliga crunched the data from 39 years of Nathan’s Famous Hot Dog Eating Contest, an annual event that challenges eaters to shove as many dogs down their throats as possible in just 10 minutes. He used a mathematical model to estimate a theoretical maximal active consumption rate (ACR) for humans.

“Through nonlinear modelling and generalized extreme value analysis, I show that humans are theoretically capable of achieving an ACR of approximately 832 g min−1 fresh matter over 10 min duration,” Smoliga wrote in the research article, which was published Wednesday in the journal Biology Letters. That translates to about 83 hot dogs in 10 minutes.

If that sounds insane, it’s not. Competitive eater Joey Chestnut demolished the competition in the Nathan’s contest this year by snarfing down 75 hot dogs (in buns) over the course of 10 minutes.

Miki Sudo, the reigning champion in the women’s division of the hot dog contest, has seen the results of the study. “I’m only 34.5 hot dogs away from perfection!” she tweeted. She managed to put away an impressive 48.5 dogs.

Smoliga took the study a step further by comparing human performance with that of some well-known eaters from the rest of the animal kingdom. It turns out people could potentially outeat a grizzly bear, but grey wolves have us beat.

There’s some fudge factor here. “The contest duration makes it difficult to directly relate ACRs between species, though comparison with existing data highlights the impressive eating capacity of humans,” Smoliga wrote.

Smoliga noted that eating competitions are unique environments where a ready and unlimited food supply and the presence of spectators may influence ACR.

The study also calls out the impressive increases in consumption performance among contest competitors over the years. Both Chestnut and Sudo set new hot dog-eating world records in 2020, making them wiener winners worthy of worship.

As for the rest of us, sticking with just a hot dog or two for dinner is probably a good idea.

China's lunar probe Chang'e-5 enters lunar orbit after perilune braking – CGTN




China’s Chang’e-5 probe decelerated and entered lunar orbit on Saturday, completing a vital step on its way to collect and return moon samples, the China National Space Administration (CNSA) announced.

The probe performed the braking at perilune without incident and entered the lunar orbit successfully, according to real-time monitoring data. Braking at perilune is a critical maneuver, as the probe, traveling at a high speed, needs to carry out braking to lower its relative velocity, to enable it to be captured by lunar gravity.

This is how you can really help reduce greenhouse gas emissions – CTV News



When many Canadians think of how they can help lower greenhouse gas emissions, they often look for ways to reduce their own carbon footprint by flying less frequently or driving an electric vehicle, for example.

However, as laudable as those actions may be, climate activists say there are more effective ways for people to become involved and make a difference.

Alex Speers-Roesch, a climate campaigner with Greenpeace Canada, explained that the phrase “carbon footprint,” which is the measure of the total greenhouse gas emissions directly or indirectly caused by an individual, organization, event, or product, was actually popularized by the multinational oil and gas company BP in the early 2000s in an attempt to put the burden of change on to the individual.  

“It’s good for people to think about the emissions associated with the things that they consume, but there’s a tendency sometimes in the way that carbon footprints are talked about and promoted that tries to put the onus on individuals and consumers for those emissions in a way that can be unfair,” he told during a telephone interview in late November.

Lauren Latour, a climate ambition co-ordinator for Climate Action Network Canada, cited a study from a few years ago that showed that just 100 companies were responsible for 70 per cent of the world’s greenhouse gas emissions since 1988.

She also referenced another recent study that claimed frequent-flying “super emitters,” consisting of just 1 per cent of the population, were responsible for half of the world’s aviation carbon emissions in 2018.

“The average Canadian is very much not responsible for the lion’s share of harmful climate change effects,” Latour said during an interview with in late November.

So while both Latour and Speers-Roesch said Canadians should be mindful of the greenhouse gas emissions associated with the goods and services they consume and how their individual choices affect the environment, they said there are other, more impactful, ways for them to address the climate emergency.

“It’s not going to be the individual actions of consumers that are going to address the climate crisis, what we really need is collective action from all of us working together to produce systemic change,” Speers-Roesch said.


Canadians interested in doing their part to reduce global greenhouse gas emissions can start by seeking out more information about the topic from environmental organizations dedicated to the cause, Speers-Roesch suggested.

He said there are many climate change groups operating in Canada, such as Greenpeace Canada, 350 Canada, Environmental Defence, and Climate Action Network Canada.

“Find a group like that, sign up for the email list, see if you can get involved,” he said. “Once you start looking, though, you start to see, ‘Oh there are opportunities everywhere.’”

Speers-Roesch said Canadians can also seek out climate change events happening in their area. For example, if there is a protest nearby, he suggested going to see what it’s about and to meet other attendees.

“As you connect with others and get more involved and get more engaged, you’ll probably have more ideas,” he said. “Before you know it, you’ll have lots of stuff to keep you busy on climate change.”


Latour acknowledged that getting involved in politics can be a “scary” thing for a lot of people, but that it doesn’t have to be and there are many opportunities to become engaged by joining community-led initiatives.

She said Canadians can join local organizations that work to influence government policy on the municipal level.

“For instance, a city is able to switch its bus fleet over from fuel combustion buses to low emissions, or hybrid or electric buses, or an electric light rail system,” she said.

Latour said Canadians can also volunteer for a mutual aid effort that is dedicated to building resiliency in their town or region. For example, she cited the groups that stepped up to help mitigate the effects of flooding in the Ottawa area over the past few years.

“In a lot of places, we see municipalities and we see smaller communities really leading the way on climate change and on climate policy,” she said.

“Individual change does matter and that individual change is getting involved in community organizing and getting involved in influencing your politics and local legislation.”

Speers-Roesch, too, said political activism is one of the most important things Canadians can do to become involved in the fight against climate change.

“The majority of the emissions are due to industry and are a result of government policy decisions so that’s really the most important and impactful place that people can focus their energies,” he said.

The Greenpeace campaigner said that Canadians should learn about their local politicians’ environmental platforms and encourage them to act.

“Call your MP, call your MPP, or city councillor,” he said. “Let them know you want them to do more on climate change.”


Finally, Speers-Roesch said Canadians can still do their part by incorporating climate change issues and pushing the conversation forward in their daily lives.

“Think about how you can bring climate activism into your existing life,” he said. “It doesn’t always necessarily have to be finding another group and joining them.”

As an example, Speers-Roesch said someone who is already part of a book club that meets on a weekly basis could suggest a book for them to read on climate change.

He said they could also organize an event within an organization they’re already involved in, such as their workplace, school, sports team, church, or temple, to raise more awareness.

“Look for a little thing that you can do each week to sort of make your voice heard and get activated and engaged on climate change,” Speers-Roesch advised. “Climate change is something that we really need to sort of infuse into every aspect of our lives and our work and everything that we do.”

Victoria home-composting system makes Time's top 100 inventions – Times Colonist



Victor Nicolov got an early Christmas present last week, when Time magazine named the Sepura home-composting system one of its 100 inventions of the year.

Nicolov, chief executive of ­Victoria-based Anvy Technologies, had his eye on the bigger prize of sending out the first shipment of his Sepura system early in the new year, but said being named to the list was exciting.

“This means there will be more people finding out there is another solution for getting rid of waste at home,” he said.

The Sepura system, which Nicolov started developing in 2018, is a smart device that attaches to a kitchen sink and acts as a filter between the drain and the drain pipe.

The system extracts all the liquid from food waste, allowing it to pass down the pipe while compost-ready organic solids are collected and held in a sealed 10-litre container that can be removed to tip onto a compost pile or into a compost collection bin.

Nicolov said the system will capture 95 per cent of the solid waste flushed down the drain, and could render obsolete the need for countertop compost bins that can smell and breed fruit flies.

Time’s list, which annually highlights inventions making the world better and smarter, noted the Sepura system may help solve the problem of the estimated 40 million tonnes of food waste Americans generate annually, preventing it from ending up in landfills or being flushed down the drain.

The $580 US system is currently available for $380 US online if pre-ordered before the company starts shipping.

Nicolov said the company has been pushing sales over the past year, marketing the product to builders and developers in particular. “The difficulty there is we’re a new product and building developers don’t like risk — they like products that have been around,” he said.

Nicolov said builders have told him, however, that they have been looking for a product to replace the outdated garburator in new homes.

A series of prototypes have been installed in homes around Victoria, and Nicolov is ­optimistic that it’s just a matter of time before Sepura becomes a must-have for new homes.

The unit can also be installed in older homes as an upgrade. Nicolov said it can be attached to any kitchen sink and does not require a custom build.

The company, which has five employees spread around B.C., is starting to ramp up large-scale manufacturing of the latest model of Sepura at a plant in Ohio.

Nicolov expects they will start shipping before the end of the first fiscal quarter in 2021.

“It’s been a ton of work but it’s super exciting,” he said.

“I can’t wait to get people’s reactions.”
