Can bees experience positive emotions?

A new study was designed to test whether bees can experience some kind of primordial “emotions”. In the study bees were trained to associate a tunnel marked with a blue flower with a sugar water treat at its end. In contrast, a green flower meant no reward at the end of the tunnel. However, when bees were…

Using Feces to Identify Species

According to a press release from Northern Arizona University, Drs. Faith Walker and Carol Chambers at the Bat Ecology & Genetics Lab have developed a system called Species From Feces to identify bat species from guano collected in field locations such as mines, caves, bridges, etc. The system takes advantage of DNA sequencing technology and an assay…

As the name implies, Clostrodium difficile (C. diff.) bacterial infections are difficult to treat because of antibiotic resistance. The problem with C. diff is that these bacteria release toxins that cause inflammation and diarrhea. In fact, C. diff is the number one cause of infectious diarrhea in hospitals as well as long-term care facilities. Studies have shown that probiotic…

Friday Cephalopod: It’s a trap!

Don’t let the pokeboys and pokegirls enslave you!

A Review of Undeniable, by Douglas Axe.

Do you remember those commercials, from a few years back, for Excedrin headache medicine? There was a whole series of them. In each, some very normal-looking and totally relatable person would talk straight to the camera, explaining that he or she suffered from terrible headaches and had tried every other remedy. The climax of each…

Reducing gas emissions…from cows

No joke: California Governor Jerry Brown signed a bill to regulate ‘gas’ emissions from cows along with other sources of greenhouse gases, of course. According to an interview from NPR, dairy cows are the number one producer of methane in California. The problem with methane is that it is a major component of smog, although according to scientists at the University…

Extreme Physiology: Radiation tolerance

Don’t let their small size fool you. Tardigrades, or ‘water bears’, are really tough animals. According to a review published in the American Scientist, these microscopic invertebrates can survive extreme variations in temperature from near absolute zero (-459 deg F) up to +302 deg F. They can also tolerate pressures that are 6 times greater than the deepest…

Very Smart Birds, Very Smart Bird Book

Crows are smart. Anyone who watches them for a while can figure this out. But that is true of a lot of things. Your baby is smart (not really). Your dog is smart (not really). Ants are smart (sort of). It takes a certain degree of objective research, as well as some serious philosophy of…

…snake, that is.

On Sept. 30th, I’m going to be co-presenting a Bio-Link webinar on Genome Engineering with CRISPR-Cas9 with Dr. Thomas Tubon from Madison College.  If you’re interested, Register here.  Since my part will be to help our audience understand the basics of this system, I prepared a short tutorial with Molecule World .  Enjoy! A Quick CRISPR Tutorial…
