A giraffe says “hum”?

Researchers at the University of Vienna are studying vocalizations from giraffes. They captured recordings of the animals “humming” during the night at local zoos. Zookeepers were surprised to learn the animals made such noises as they are not heard during the day. Researcher Dr. Angela Stöger remarked to the New Scientist, “I was fascinated, because these signals…

How to attract a female

A female mouse that is. You may recall a post from several years ago when we talked about how rats seem to “laugh” when tickled. Back in April 2015 researchers at Duke University presented a video that showed male mice “singing” a tune after either smelling the urine of a female mouse or being in her presence.…

Economical reasons to save bats

New research published in the Proceedings of the National Academy of Sciences shows that bats are important nocturnal predators of insects that would otherwise attack crops. In addition, bats help to protect crops from fungal infections brought on by pests and are important pollinators. According to the new research, the pest-control services provided by bats for corn crops alone is…

A vaccine for cancer

Dr. Mark Mamula at Yale University has been working on developing a vaccine for cancer. Here is an interview featuring Dr. Mamula discussing how dogs are helping researchers test a vaccine that so far, has shown promise in fighting cancer growth. Video Source: NBC www.King5.com

The wonders of melatonin

  In a new study published in the American Journal of Physiology Regulatory, Integrative and Comparative Physiology, researchers at the University of Wisconsin, La Crosse were interested in understanding how thirteen-lined ground squirrels protect their brains during arousal from hibernation. This is a period of time in which the animals experience major changes in their body…

The hummingbird micropump

A new study published in the Proceedings of the Royal Society B: Biological Sciences provides evidence that hummingbird tongues act like micropumps when drinking nectar. This finding is in contrast to the long-held belief that their tongues use capillary action to pull in fluids. A team of researchers from the University of Connecticut used high-speed film to…

Answer: pregnancy. Unlike most animals, it is the male seahorses that give birth to live young. A new study conducted at the University of Sydney and published in Molecular Biology and Evolution, found that the male seahorses not only carry out the pregnancy, they also supply nutrients to the developing embryos, including fats and calcium. The researchers suspect…

Another new study published in Nature Communications shows follows along with the prior post and shows that ancestral dogs were ambush hunters that evolved from forest dwelling animals similar to a mongoose (or a cat).  An international team of researchers studied archived samples of elbows and teeth of multiple species of dogs that lived between 40 – 2…

Proof cats outcompete dogs?

New research suggests that cats may have played a role in the extinction of about 40 species of wild dogs by simply out-hunting them and therefore consuming more food. The study noted that dogs first appeared in North America around 40 million years ago and by 22 million years ago there were over 30 species of wild dogs. Cats arrived…

Malnutrition during pregnancy is a major global health issue that leads to restricted growth of developing fetuses making them more prone to death and disease. In fact, babies born from poorly nourished mothers are more likely to develop obesity, metabolic syndrome and cardiovascular disease as adults. Researchers from the University of Colorado and University of Texas Health…
