Dr. Steve Goodman’s Work as a Field Biologist in Madagascar

Dr. Steve Goodman‘s work is a legendary Field Biologist and spends 9-10 months out of the year conducting research in other countries, with a focus on Madagascar for nearly 30 years. Learn more about the future of Madagascar’s biodiversity and research.

This video is from the great Brain Scoop channel with Emily Graslie; if you are not following that channel I highly recommend doing so for people interested in science.

Elephants Learn to Cooperate to Reach Their Objective

This clip shows elephants learning to work together to achieve what they can’t achieve alone (from BBC’s Super Smart Animals). It is interesting to see what animals are capable of. See the related post links for more amazing animal behavior.

Insect Architecture

In this webcast The Brain Scoop takes an interesting look at the homes of eusocial animals and other insects. The video includes many interesting details including that adult weaver ants can’t produce the silk used to weave leaves together so they pick up their larva and use them like a glue stick.

Engineering Mosquitos to Prevent the Transmission of Diseases

Mosquitos are responsible for huge amount of suffering and death. In 2015 200,000,000 people were infected with malaria and 500,000 died.

It is amazing what knowledge science has provided about the causes of human disease. It is great to have videos like this available that let us learn a bit about it from a short and understandable video.

Using our scientific knowledge to design and implement solutions offers great possibilities. But we also have to worry about the risks of such attempts. Making decisions about what risks to take requires well informed people that are able to understand the opportunities and risks and make intelligent decisions.

How Eratosthenes Estimated the Circumference of the Earth Over 2,000 Years Ago

In this video Carl Sagan explains how Greek astronomer Eratosthenes, in 200 BC, was able to deduce and calculate the earth was a sphere about 40,000 km in circumference.

It is wonderful to see how a bit of thought and curiosity have lead mankind to learn so much.

Medicinal Plants

Another great webcast from SciShow. In this webcast Hank Green discusses how we have used plants to treat us and improve our health.

In the webcast, Hank also does a good job touching a bit on the scientific inquiry process (which is something I find interesting and I think is very important for people living in society today to understand).

Webcasts on the Human Microbiome

The human microbiome is a very interesting aspect of our health and biology.

The 99% figure they quote is mainly silly. It might be technically accurate, but it is much more misleading than accurate (if it is accurate). We have more non-human cells than human but those cells are much smaller and we are overwhelmingly made up of human cells by weight (95+%).

The complexity of healthy bodies is far from understood. It is interesting to watch our understanding of the balancing act going on inside of us. Many foreign “invaders” are critical to our health.

Using Diatom Algae to Deliver Chemotherapy Drugs Directly to Cancer Cells

I am thankful for scientists doing the time consuming and important research to find new ways to fight disease. Here is an interesting webcast discussing how chemotherapy is used to fight cancer and how scientists are looking to algae to deliver the chemotherapy drugs to better target cancer cells (while not savaging our health cells).

I am also thankful to the funding sources that pay for this research (and for cool explanations of science, like SciShow).

Read more about the genetically engineered algae kills 90% of cancer cells without harming healthy ones. The algae are a diatom and many diatoms look very cool.

Sadly the actual research paper (by government funded university professors) is published by a closed science publisher (when are we finally going to stop this practice that was outdated over a decade ago?). Thankfully those responsible for SciShow are much more interested in promoting science than maintaining outdated business models (in direct contrast to so many science journal publishers).

Exercise Is Really Really Good for You

Nice webcast that reviews the benefits of exercise that are confirmed by medical studies.

Other than [not] smoking there are few modifiable risk factors that seem to have the huge impact on heath activity does…

150 minutes a week of moderate (walking briskly, biking, even mowing the lawn maybe) activity (30 minutes a day 5 days a week) is a decent target for a minimum amount of activity for most people. I have not bought a car since my move (2 months ago) and walk to the grocery store, library, bank, subway, restaurants which is easily 30 minutes and usually more each trip. And for further away places I am biking.

Another option is 25 minutes of vigorous activity 3 times a week and 2 days a week of weight training. Basketball is my favorite form of vigorous activity and sometimes my biking and yard work reach that mark. I like swimming (and I did swim a fair amount when I had a pool at my condo but I don’t swim now as it isn’t right downstairs from my bedroom). I like vigorous activity as I end up feeling refreshed and it serves as a noticeable form of stress release for me.

Camera Trap Images of Very Rare Wild Cats

This video show some wonderful images from remote cameras equipped to film when an animal is spotted. These camera have aided scientists in understanding wildlife in their natural environment and also by providing us cool images.
