You are shopping in a busy supermarket and you're ready to pay up and go home. You perform a quick visual sweep of the checkout options and immediately start ramming your cart through traffic toward an appealingly  line halfway across the store with less people. As you wait in line and start reading nutrition labels, you can't help but calculate that the 529 calories contained in a single slice of your Key lime cheesecake amounts to one-fourth of your recommended daily caloric allowance and will take you 90 minutes on the elliptical to burn off and you'd better just stick the thing behind this stack of Soap Opera Digests and hope a clerk finds it before it melts.

numbers_sense_1

One shopping spree, two distinct number systems in play. Whenever we choose a shorter grocery line over a longer one, or a bustling restaurant over an unpopular one, we rally our approximate number system, an ancient and intuitive sense that we are born with and that we share with many other animals. Rats, pigeons, monkeys, babies — all can tell more from fewer, abundant from stingy. An approximate number sense is essential to brute survival: how else can a bird find the best patch of berries, or two baboons know better than to pick a fight with a gang of six?

A new cancer treatment called Hipec (Hyperthermic Intraperitoneal Chemotherapy) is slowly growing in popularity -- one that involves surgically removing cancerous tumors from the abdominal cavity, then bathing the cavity with hot chemotherapy to kill any cancer cells left in there.

The idea behind the treatment is that heat at 42 degrees Celsius (107.6 degrees Fahrenheit) is able to kill cancer cells without affecting normal cells in the body, according to the University of San Diego Moores Cancer Center, which offers the treatment to qualifying patients.

Creating a Blader in the Lab

The Wake Forest Institute for Regenerative Medicine (WFIRM) is a leader in translating scientific discovery into clinical therapies. Physicians and scientists at WFIRM were the first in the world to engineer laboratory-grown organs that were successfully implanted into humans. Today, this interdisciplinary team is working to engineer more than 30 different replacement tissues and organs and to develop healing cell therapies—all with the goal to cure, rather than merely treat, disease.

stem cell research 600x450

Stem cells are CELLS found in all multi cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiate into a diverse range of specialized cell types. Research in the stem cell field grew out of findings by Ernets A. McCulloch and James E. Till at the University of Toronto in the 1960s.

lightning red sky

What is Lightning?

Lightning is the phenomenon which accompanies the discharge of atmospheric charges from cloud to cloud or from cloud to earth. As lightning seeks the path of least resistance, it naturally tends to follow the shortest course between the cloud and the earth, such as buildings or towering projections.
