Archaeologists have made an interesting discovery while excavating the late Bronze Age/early Iron Age settlement named Cladh Hallan on the island of South Uist in the Outer Hebrides, Scotland. They have uncovered four human skeletons buried at regular intervals beneath three roundhouses dating from the 11th century BC: an adult male, an adult female, a 10–14-year-old girl and a 3-year-old child. The careful arrangement of these burials directly below the roundhouses led archaeologists to initially hypothesize that these might be foundation burials—an ancient practice in which people, usually younger people, were sacrificed and buried under a building’s foundation in the belief that their blood and spirit would protect and strengthen the building and building site. As strange as that custom seems to us, it gets weirder. Two of these skeletons showed signs of mummification and contained skeletal elements from multiple individuals intentionally pieced together to form intact skeletons.

General
Up, Up, and Away…..
Who doesn’t love a good party? One thing that surely signals a party is that telltale cluster of balloons, tugging cheerfully from the mailbox at the end of the driveway, almost chanting “Party over here!”. Think twice, however, before making that next helium balloon purchase.
Helium, that lighter than air element which is responsible for giving helium balloons their gravity-defying loft, is the second most common element in the universe, is non-reactive, and turns into a liquid at very cold temperatures without freezing solid. All of these properties have made helium a useful tool in medicine, space exploration, electronics, and manufacturing. The supplies of helium are dwindling and experts estimate that reserves of this natural resource could be gone within the next 25-50 years or so. There are ways to reclaim helium from the atmosphere, but they are very expensive and will certainly drive up the cost of products and services that require helium, such as MRIs and LCD televisions.
It may seem like a small contribution, but choosing air filled balloons for your next festivity can help. Try air inflated balloons hung or draped from the ceiling or arranged as centerpieces. Or skip those balloons all together and spend your money on something your guests will really appreciate…like a bigger cake!
Walking the Dog, Prefrontal Cortex Engaged
A friend and I were recently at a local dog park, walking his Sheltie and Australian shepherd, and my two standard poodles. Our dogs are not daily visitors to the dog park, and while his dogs are well-behaved and subtle in their approach to other dogs, my poodles’ enthusiasm is not always in their best interest.
In addition, one of my dogs seems to take issue with certain of the protection dog breeds, like German Shepherds, as well as some of the sled dog breeds. Generally, if a dog has pointed ears, I am on the alert for bad behavior.
For that matter, the protection dogs don’t seem to much care for fluffy, bouncy poodles. Annoying, you know? A dog’s trying to keep order and make the world safe, and here comes that poodle, bouncing along without a care in the world. There’s a lot of danger out there and the poodles are simply not paying attention. They jog along meeting people and dogs like they are running for mayor; darn poodles.
Occasionally it has seemed that the attitude problem is not exclusive to my dog.
People often say, “Oh, standard poodles are such smart dogs”. But you’d think a smart dog would not choose a big, guard dog breed with which to make trouble. Continue reading “Walking the Dog, Prefrontal Cortex Engaged”
And Then There Were None, Or Were There? Lonesome George and the Giant Tortoises of the Galapagos Islands
This week science lost a celebrity of the most unusual sort. Known to people around the world as Lonesome George, he was recognized as the last living member of his subspecies, the Pinta giant tortoise (Geochelone abingdoni) one of the giant tortoises of the Galapagos Islands. These slow and steady creatures hold a special place in science history. Observing differences between the giant tortoise populations of different Galapagos Islands helped a young Charles Darwin develop his theory of evolution.

Want Your Kids to Eat Their Vegetables? Start Them Early and Give Them Water
As I write this, a can of diet soda sits open on my desk (where I am eating my lunch) and I am fighting the urge to supplement my lunch with a bag of chips out of the vending machine. The reusable, BPA-free glass I keep at my desk for ice water sits neglected, as does the apple I brought in my lunch. So why, if I have an apple sitting right there, am I tempted to visit the vending machine for chips? New research suggests that the blame could lie with that can of diet soda.
The study, made available online ahead of publication (1), found that from a very early age, people associate sweeten drinks with salty and higher fat foods such as pizza and French fries (or chips). Perhaps partly as a result of this association, young people (ages 19–23 years) viewed unfavorably the pairing of a sweetened drink with raw or cooked vegetables. The test subjects showed strong reactions (either positive or negative) to the pairing of sweetened drinks with certain foods. In contrast, water didn’t evoke strong any reactions indicating that it was viewed as reasonable complement to most food. Continue reading “Want Your Kids to Eat Their Vegetables?

There Are Tadpoles on the Kitchen Floor
As a mother, there are things that you just can not anticipate. Take this morning for example.
“Mom!” My daughter yelled, “There are tadpoles on the kitchen floor.”
The worst part was I knew I had only myself to blame. Continue reading “There Are Tadpoles on the Kitchen Floor”
The Biggest Blunders of Job Searching: Part 3 Presentations
No matter what type of job you are interviewing for, you may be asked to give a seminar or presentation. When I interviewed for my first HR job, I had to give a presentation on any topic I wanted. Other jobs specify that you need to give a presentation on a topic specifically related to the job. In my case, they were looking for both presentation skills and my ability to teach. When asked to present on a job-related topic, a potential employer may be looking for your ability to organize information and your knowledge on the topic. Presentations can be scary, but some good old-fashioned preparation can make things go much more smoothly.
In order to prepare, you need to know what your audience is looking for. Read on for some things to avoid during your presentation. Continue reading “The Biggest Blunders of Job Searching: Part 3 Presentations”
Want to Look More Attractive? Eat More Fruits and Vegetables.
Fruits and vegetables are an important dietary source of nutrients, including antioxidants that help stave off cellular damage due to oxidative stress and could protect us against a variety of age-related diseases, cardiovascular disease, diabetes and perhaps some forms of cancer. Nutrition experts advise us to eat at least five servings of fruits and vegetables each day, but many of us don’t. Furthermore, the health benefits of a vegetable-rich diet aren’t necessarily enough motivation for us to change our diets, even though we know we should. A recent finding reported in PLoS ONE gives us an extra reason to incorporate more fruits and vegetables into our menus: We might just improve our skin color and look more attractive.

How Does Your Garden Grow? Why, Naturally, Of Course!
How does your garden grow? Well, normally, I would tell you that it doesn’t, not until late May anyway. But this year, the grass is green, the trees are flowering and the garden is already tilled in early April! Unseasonably warm temperatures come with questions: Is this global warming? The 2012 apocalypse? When can I start planting???
I fell in love with vegetable gardening about three years ago when a coworker brought in some extra seedlings. There is nothing like watching food grow up from a mere seed and then harvesting and eating! At Promega, we have some community garden space, which is great since my black walnut tree at home kills all my tomatoes. We are attempting to keep this garden space organic. As a new gardener, I am still learning what this means, so I thought I would share some of my new-found information.

The pharaoh Tutankhamun ruled ancient Egypt during the 18th dynasty of the New Kingdom (circa 1550–1295 BC), one of the most powerful royal houses in ancient Egypt. Although he sat on the throne for only 9 years and died at the young age of 19, he is one of the most well known pharaohs, due largely in part to the discovery of his intact tomb by archaeologist Howard Carter in 1922. The tomb was filled with riches befitting a king, including an elaborate sarcophagus with a gold burial mask and statues of ancient Egyptian gods such as Osiris and Anubis, as well as gold jewelry, statues and images of servants, ornate furniture, models of boats and other items that the pharaoh would need in the afterlife. A lesser known item discovered in his tomb was an undecorated wooden box in which two small gilded coffins lay side by side. These coffins held the mummified remains of King Tutankhamun’s two stillborn daughters. Recently, researchers examined these remains in detail to determine their gestational ages and characterize any congenital abnormalities that they might have inherited from the boy king.
