Botany One reviews Food: Delicious Science, a newish TV series from James Wong and Michael Mosley, originally produced on BBC2 as The Secrets of Your Food. Among the "entertaining stories" that Ian Street singles out for special praise: Watching James Wong and Michael Mosley participate in a chili eating contest to illustrate just how far humans have gone to explore what is edible and explain the biochemistry of capsaicin.
Tackling the problem of antibiotic resistance at (one) source In the past year or so there has been a slew of high-level meetings pointing to antibiotic resistance as a growing threat to human well-being. But then, resistance was always an inevitable, Darwinian consequence of antibiotic use. Well before penicillin was widely available, Ernst Chain, who went on to win a Nobel Prize for his work on penicillin, noted that some bacteria were capable of neutralising the antibiotic. What is new about the recent pronouncements and decisions is that the use of antibiotics in agriculture is being recognised, somewhat belatedly, as a major source of resistance. Antibiotic manufacturers and the animal health industry have, since the start, done everything they can to deny that. Indeed, the history of efforts to regulate the use of antibiotics in agriculture reveals a pretty sordid approach to public health. But while it can be hard to prove the connection between agriculture and a specific case of antibiotic resistance, a look at hundreds of recent academic studies showed that almost three quarters of them did demonstrate a conclusive link. Antibiotic resistance – whether it originates with agriculture or inappropriate medical use – takes us back almost 100 years, when infectious diseases we now consider trivial could, and did, kill. It reduces the effectiveness of other procedures too, such as surgery and chemotherapy, by making it more likely that a subsequent infection will wreck the patient’s prospects. So it imposes huge costs on society as a whole. Maybe society as a whole needs to tackle the problem. The Oxford Martin School, which supports a portfolio of highly interdisciplinary research groups at Oxford University, has a Programme on Collective Responsibility for Infectious Disease. They recently published a paper proposing a tax on animal products produced with antibiotics. Could that possibly work?
Here’s another great example of a negative externality. Too often capitalism brushes over these and creates a larger longer term cost by not taking these into account. It’s almost assuredly the case that taxing the use of these types of antibiotics across the broadest base of users (eaters) (thereby minimizing the overall marginal cost), would help to minimize the use of these or at least we’d have the funding for improving the base issue in the future. In some sense, the additional cost of eating organic meat is similar to this type of “tax”, but the money is allocated in a different way.
Not covered here are some of the economic problems of developing future antibiotics when our current ones have ceased to function as the result of increased resistance over time. This additional problem is an even bigger worry for the longer term. In some sense, it’s all akin to the cost of smoking and second hand smoke–the present day marginal cost to the smoker of cigarettes and taxes is idiotically low in comparison to the massive future cost of their overall health as well as that of the society surrounding them. Better to put that cost upfront for those who really prefer to smoke so that the actual externalities are taken into account from the start.
This excellent story reminds me of a great series of stories that PBS NewsHour did on the general topic earlier this year.

What a great little shop and concept!
My first time in and they not only had some excellent samples, but comped my first bundt. I’m impressed at how on-message and lovely the entire concept of the store really was. I’m already guessing I know how I’m going to add 20 pounds before the holidays are over.
Maybe you’ve seen the stories about a peanut, prosaically named Carolina Runner No. 4? In 2017 it will be ready to be grown in commercial quantities, having faded gently away from being the primary peanut before the 1840s to a reasonable contender into the 1910s to presumed extinct by the 1950s. Professor David Shields, an historian at the University of South Carolina, found it in a genebank as part of a project by the Carolina Gold Rice Foundation, which he chairs, to restore the crucial varieties of the American South. It’s a fine story, but a couple of things bothered me. One, how do they know it is “the first peanut cultivated in North America” or “the South’s original peanut” as all the articles claim. Two, although everyone acknowledges that the peanut came to the USA not from South America, it’s ancestral home, but from West Africa with enslaved people, nobody seems to be much interested in what on earth it was doing in West Africa, or the consequences of its introduction there by the Portuguese. The podcast looks a bit at the question of whether Carolina Runner No. 4 – henceforth Carolina African Runner – is indeed the “ur-peanut”; I conclude that it doesn’t really matter.

This afternoon on the Food Network, I saw this surprising and shocking commercial:
I was so surprised that I actually had to rewind and rewatch it to make sure I’d actually heard it correctly.
Given the casting and the bright cinematography reminiscent of a Saturday Night Live skit (particularly with the talented and heavily underrated Evan Arnold), I was hoping to have a nice little laugh, but I was stunned by the tag line at the end. And no, I’m not talking about the advertising agency’s designated tagline “Booyah!”, which cleverly buries the lede; I’m talking about the tagline they designed to be remembered and the one which threw me: “Bush’s Baked Beans: The Vegetable Kids Love.”
While technically correct in so many of the wrong ways based on the USDA’s definition of vegetables, this commercial and its definition of vegetable belies the spirit in which the vast majority of American viewers are going to view and understand it. (And I’ll freely admit that at any given time, I’ve got up to two quarts of cooked beans in my refrigerator and a massive 25 pound bag of dried beans in the larder.)
I’ll at least give them credit that the dish served in the commercial did feature chicken as the protein, which by the USDA guidelines then pushes the beans into the “vegetable” column rather than the protein column in this meal. And I’ll further credit them that the serving sizes are almost reasonable for children of this age, though I suspect that from a commercial production standpoint, the small servings were more a function of trying to better feature the beans on the plate. However, if this is a balanced dinner, I’m guessing that the children aren’t getting their USDA RDA for “true” vegetables and fruit and are drastically overdosing on protein.
Fortunately, this commercial isn’t as egregious as Cheetos suggesting that they’re part of the vegetable food group because they’re made out of corn byproduct (incidentally, they have a pitiful Overall Nutritional Quality Index of 4!), but it does leave us on the terribly slippery slope that probably isn’t helping the overall American diet.
Beans and peas are the mature forms of legumes. They include kidney beans, pinto beans, black beans, lima beans, black-eyed peas, garbanzo beans (chickpeas), split peas and lentils. They are available in dry, canned, and frozen forms. These foods are excellent sources of plant protein, and also provide other nutrients such as iron and zinc. They are similar to meats, poultry, and fish in their contribution of these nutrients. Therefore, they are considered part of the Protein Foods Group. Many people consider beans and peas as vegetarian alternatives for meat. However, they are also considered part of the Vegetable Group because they are excellent sources of dietary fiber and nutrients such as folate and potassium. These nutrients, which are often low in the diet of many Americans, are also found in other vegetables.
Because of their high nutrient content, consuming beans and peas is recommended for everyone, including people who also eat meat, poultry, and fish regularly. The USDA Food Patterns classify beans and peas as a subgroup of the Vegetable Group. The USDA Food Patterns also indicate that beans and peas may be counted as part of the Protein Foods Group. Individuals can count beans and peas as either a vegetable or a protein food.
For more information on beans, I’ll recommend the following more reliable resources:
- Dry Beans information from the United States Department of Agriculture | Economic Research Service
- Beans and peas are unique foods | USDA ChooseMyPlate.gov
- Food Pyramid
Two of my favorite topics: Food and Science!
The University of East Anglia in the UK in association with the Institute of Food Research is offering a free four week course Identifying Food Fraud. It’s an introduction to modern analytical science techniques and how they can be used to uncover food fraud.
I know many people who could identify a fake Louis Vuitton (LVMH) purse, a knock off Christian Louboutin, or a sham Rolex, but who simultaneously are overly religious about their food brands and topics like organic food and couldn’t similarly identify the fakes they’re eating because of fraud in food labeling and misdirection and legerdemain within the food supply chain. Finally there’s a course to help everyone become smarter consumers.
The food industry is one of the most important commercial sectors in the world. Everyone uses it, but how many people abuse it? As we witness the increasing globalisation of the supply chain, a growing challenge is verifying the questionable identity of raw materials in the food we eat.
In this course we will look at topical issues concerning ‘food fraud’ and explore ways in which analytical chemistry can help in its identification and prevention. We’ll share fascinating examples, such as the history of white bread and a surprising ingredient once found in bitter beer.
The University of East Anglia has joined forces with the world-renowned Institute of Food Research (IFR) to bring you this unique course. You’ll be led by Kate Kemsley, a specialist in the use of advanced instrumentation for measuring the chemical composition of food materials. Course content is linked with UEA’s MChem postgraduate programme, which supports final-year students’ practical research projects in this area of science.
For those interested the course starts on October 26, 2015.Syndicated copies to:
Congratulations on your new math class, and welcome to the “family”!
Invariably the handful of new students every year eventually figure the logistics of campus out, but it’s easier and more fun to know some of the options available before you’re comfortable halfway through the class. To help get you over the initial hump, I’ll share a few of the common questions and tips to help get you oriented. Others are welcome to add comments and suggestions below. If you have any questions, feel free to ask anyone in the class, we’re all happy to help.
First things first, for those who’ve never visited UCLA before, here’s a map of campus to help you orient yourself. Using the Waze app on your smartphone can also be incredibly helpful in getting to campus more quickly through the tail end of rush hour traffic.
Whether you’re a professional mathematician, engineer, physicist, physician, or even a hobbyist interested in mathematics you’ll be sure to get something interesting out of Dr. Miller’s math courses, not to mention the camaraderie of 20-30 other “regulars” with widely varying backgrounds (from actors to surgeons and evolutionary theorists to engineers) who’ve been taking almost everything Mike has offered over the years (and yes, he’s THAT good — we’re sure you’ll be addicted too.) Whether you’ve been away from serious math for decades or use it every day or even if you’ve never gone past Calculus or Linear Algebra, this is bound to be the most entertaining thing you can do with your Tuesday nights in the Autumn and Winter. If you’re not sure what you’re getting into (or are scared a bit by the course description), I highly encourage to come and join us for at least the first class before you pass up on the opportunity. I’ll mention that the greater majority of new students to Mike’s classes join the ever-growing group of regulars who take almost everything he teaches subsequently.
Don’t be intimidated if you feel like everyone in the class knows each other fairly well — most of us do. Dr. Miller and mathematics can be addictive so many of us have been taking classes from him for 5-20+ years, and over time we’ve come to know each other.
Tone of Class
If you’ve never been to one of Dr. Miller’s classes before, they’re fairly informal and he’s very open to questions from those who don’t understand any of the concepts or follow his reasoning. He’s a retired mathematician from RAND and long-time math professor at UCLA. Students run the gamut from the very serious who read multiple textbooks and do every homework problem to hobbyists who enjoy listening to the lectures and don’t take the class for a grade of any sort (and nearly every stripe in between). He’ll often recommend a textbook that he intends to follow, but it’s never been a “requirement” and more often that not, the bookstore doesn’t list or carry his textbook until the week before class. (Class insiders will usually find out about the book months before class and post it to the Google Group – see below).
His class notes are more than sufficient for making it through the class and doing the assigned (optional) homework. He typically hands out homework in handout form, so the textbook is rarely, if ever, required to make it through the class. Many students will often be seen reading various other texts relating to the topic at hand as they desire. Usually he’ll spend an 45-60 minutes at the opening of each class after the first to go over homework problems or questions that anyone has.
For those taking the class for a grade or pass/fail, his usual policy is to assign a take home problem set around week 9 or 10 to be handed in at the penultimate class. [As a caveat, make sure you check his current policy on grading as things may change, but the preceding has been the usual policy for a decade or more.]
Lot 9 – Located at the northern terminus of Westwood Boulevard, one can purchase a parking pass for about $12 a day at the kiosk in the middle of the street just before Westwood Blvd. ends. The kiosk is also conveniently located right next to the parking structure. If there’s a basketball game or some other major event, Lot 8 is just across the street as well, though it’s just a tad further away from the Math Sciences Building. Since more of the class uses this as their parking structure of choice, there is always a fairly large group walking back there after class for the more security conscious.
Lot 2 – Located off of Hilgard Avenue, this is another common option for easy parking as well. While fairly close to class, not as many use it as it’s on the quieter/darker side of campus and can be a bit more of a security issue for the reticent.
Tip: For those opting for on-campus parking, one can usually purchase a quarter-long parking pass for a small discount at the beginning of the term.
Westwood Village and Neighborhood – Those looking for less expensive options street parking is available in the surrounding community, but use care to check signs and parking meters as you assuredly will get a ticket. Most meters in the surrounding neighborhoods end at either 6pm or 8pm making parking virtually free (assuming you’re willing to circle the neighborhood to find one of the few open spots.)
There are a huge variety of lots available in the Village for a range of prices, but the two most common, inexpensive, and closer options seem to be:
- Broxton Avenue Public Parking at 1036 Broxton Avenue just across from the Fox Village and Bruin Theaters – $3 for entering after 6pm / $9 max for the day
- Geffen Playhouse Parking at 10928 Le Conte Ave. between Broxton and Westwood – price varies based on the time of day and potential events (screenings/plays in Westwood Village) but is usually $5 in the afternoon and throughout the evening
More often than not a group of between 4 and 15 students will get together every evening before class for a quick bit to eat and to catch up and chat. This has always been an informal group and anyone from class is more than welcome to join. Typically we’ll all meet in the main dining hall of Ackerman Union (Terrace Foodcourt, Ackerman Level 1) between 6 and 6:30 (some with longer commutes will arrive as early as 3-4pm, but this can vary) and dine until about 6:55pm at which time we walk over to class.
The food options on Ackerman Level 1 include Panda Express, Rubio’s Tacos, Sbarro, Wolfgang Puck, and Greenhouse along with some snack options including Wetzel’s Pretzels and a candy store. One level down on Ackerman A-level is a Taco Bell, Carl’s Jr., Jamba Juice, Kikka, Buzz, and Curbside, though one could get takeout and meet the rest of the “gang” upstairs.
There are also a number of other on-campus options as well though many are a reasonable hike from the class location. The second-closest to class is the Court of Sciences Student Center with a Subway, Yoshinoya, Bombshelter Bistro, and Fusion.
Naturally, for those walking up from Westwood Village, there are additional fast food options like In-N-Out, Chick-fil-A, Subway, and many others.
For those who’ve already eaten or aren’t hungry, you’ll often find one or more of us browsing the math and science sections of the campus bookstore on the ground level of Ackerman Union to kill time before class. Otherwise there are usually a handful of us who arrive a half an hour early and camp out in the classroom itself (though this can often be dauntingly quiet as most use the chance to catch up on reading here.) If you arrive really early, there are a number of libraries and study places on campus. Boelter Hall has a nice math/science library on the 8th Floor.
Mid-class Break Options
Usually about halfway through class we’ll take a 10-12 minute coffee break. For those with a caffeine habit or snacking urges, there are a few options:
Kerckhoff Hall Coffee Shop is just a building or two over and is open late as snack stop and study location. They offer coffee and various beverages as well as snacks, bagels, pastries, and ice cream. Usually 5-10 people will wander over as a group to pick up something quick.
The Math Sciences Breezeway, just outside of class, has a variety of soda, coffee, and vending machines with a range of beverages and snacks. Just a short walk around the corner will reveal another bank of vending machines if your vice isn’t covered. The majority of class will congregate in the breezeway to chat informally during the break.
The Court of Sciences Student Center, a four minute walk South, with the restaurant options noted above if you need something quick and more substantial, though few students use this option at the break.
Bathrooms – The closest bathrooms to class are typically on the 5th floor of the Math Sciences Building. The women’s is just inside the breezeway doors and slightly to the left. The men’s rooms are a bit further and are either upstairs on the 6th floor (above the women’s), or a hike down the hall to the left and into Boelter hall. I’m sure the adventurous may find others, but take care not to get lost.
Informal Class Resources
Over the years, as an informal resource, members of the class have created and joined a private Google Group (essentially an email list-serv) to share thoughts, ideas, events, and ask questions of each other. There are over 50 people in the group, most of whom are past Miller students, though there are a few other various mathematicians, physicists, engineers, and even professors. You can request to join the private group to see the resources available there. We only ask that you keep things professional and civil and remember that replying to all reaches a fairly large group of friends. Browsing through past messages will give you an idea of the types of posts you can expect. The interface allows you to set your receipt preferences to one email per message posted, daily digest, weekly digest, or no email (you’re responsible for checking the web yourself), so be sure you have the setting you require as some messages are more timely than others. There are usually only 1-2 posts per week, so don’t expect to be inundated.
Depending on students’ moods, time requirements, and interests, we’ve arranged informal study groups for class through the Google Group above. Additionally, since Dr. Miller only teaches during the Fall and Winter quarters, some of us also take the opportunity to set up informal courses during the Spring/Summer depending on interests. In the past, we’ve informally studied Lie Groups, Quantum Mechanics, Algebraic Geometry, and Category Theory in smaller groups on the side.
As a class resource, some of us share a document repository via Dropbox. If you’d like access, please make a post to the Google Group.
Many people within the class use Livescribe.com digital pens to capture not only the written notes but the audio discussion that occurred in class as well (the technology also links the two together to make it easier to jump around within a particular lecture). If it helps to have a copy of these notes, please let one of the users know you’d like them – we’re usually pretty happy to share. If you miss a class (sick, traveling, etc.) please let one of us know as the notes are so unique that it will be almost like you didn’t miss anything at all.
You can typically receive a link to the downloadable version of the notes in Livescribe’s Pencast .pdf format. This is a special .pdf file but it’s a bit larger in size because it has an embedded audio file in it that is playable with the more recent version of Adobe Reader X (or above) installed. (This means to get the most out of the file you have to download the file and open it in Reader X to get the audio portion. You can view the written portion in most clients, you’ll just be missing out on all the real fun and value of the full file.) With the notes, you should be able to toggle the settings in the file to read and listen to the notes almost as if you were attending the class live.
Viewing and Playing a Pencast PDF
Pencast PDF is a new format of notes and audio that can play in Adobe Reader X or above.
You can open a Pencast PDF as you would other PDF files in Adobe Reader X. The main difference is that a Pencast PDF can contain ink that has associated audio—called “active ink”. Click active ink to play its audio. This is just like playing a Pencast from Livescribe Online or in Livescribe Desktop. When you first view a notebook page, active ink appears in green type. When you click active ink, it turns gray and the audio starts playing. As audio playback continues, the gray ink turns green in synchronization with the audio. Non-active ink (ink without audio) is black and does not change appearance.
Audio Control Bar
Pencast PDFs have an audio control bar for playing, pausing, and stopping audio playback. The control bar also has jump controls, bookmarks (stars), and an audio timeline control.
Active Ink View Button
There is also an active ink view button. Click this button to toggle the “unwritten” color of active ink from gray to invisible. In the default (gray) setting, the gray words turn green as the audio plays. In the invisible setting, green words seem to write themselves on blank paper as the audio plays.
