Is The Hippopotamus The Closest Living Relative To The Whale?:
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales. It also turns out, the two are swimming in a bit of controversy. Jessica Theodor, an associate professor in the Department of Biological Sciences at the University of Calgary, and her colleague Jonathan Geisler, associate professor at Georgia Southern University are disputing a recent study that creates a different family tree for the hippo.
Female Mammals Follow Their Noses To The Right Mates:
Female birds often choose their mates based on fancy feathers. Female mammals, on the other hand, may be more likely to follow their noses to the right mate. That's one conclusion of Cambridge zoologist Tim Clutton-Brock and Harvard researcher Katherine McAuliffe, whose review of evidence for female mate choice is published in the March 2009 issue of The Quarterly Review of Biology.
Change Of Lighting Could Drastically Reduce Bird Death By Collision With Communication Towers:
Each year, it is estimated that millions of birds collide with communication towers. Joelle Gehring of the Michigan Natural Features Inventory at Michigan State University and her colleagues discovered that a simple alteration of the lighting scheme on these towers may reduce bird mortality by as much as 71 percent.
Iron Is Involved In Prion Disease-associated Neuronal Demise:
Imbalance of iron homeostasis is a common feature of prion disease-affected human, mouse, and hamster brains, according to a new study by Dr. Neena Singh and colleagues at Case Western Reserve University School of Medicine, alongside collaborators from Creighton University.
