Is your cat amazing … or is there a parasite in your brain that exercises mind control? Get the facts on toxoplasmosis.
—
Today, about a third of the world’s population is infected with a strange disease called toxoplasmosis — and most of them never even know it. And while the parasite can multiply in practically any host, it can only reproduce sexually in the intestines of cats. Could this disease be the reason so many people love cats and keep them as pets? Jaap de Roode shares what we know about toxoplasmosis.

Could Vitamin D be the miracle supplement? Brigham and Womens Hospital research indicates that Vitamin D may help defeat asthma in children, hip fractures in adults and maybe a whole lot more.

Common types of wound
Contusion
A contusion is more commonly called a bruise. It is usually caused by a blunt blow, the overlying skin is unbroken, but tissues and blood vessels below are damaged. The discolouration is caused by bleeding from small vessels into the tissues. Red blood cells trapped in the tissue spaces become deoxygenated anddark coloured. Bruising can also develop after deeper tissues, such as bones are damaged, and may only become apparent after a period of time as blood tracks towards the body surface.
If blood collects in a discrete pool within the tissues this is described as a haematoma. As the blood in a haematoma is well consolidated it may cause pressure effects on surrounding tissues, these may include pain and nerve compression. There is a risk a haematoma may become infected and some need to be surgically evacuated.
Abrasion
An abrasion is a scrape or graze. Typically, there is a superficial surface wound involving the epidermis and part of the dermis. As dermal nociceptors are exposed in the damaged dermis, these wounds are often very painful. Some abrasions can however, be deeper wounds involving tissues below the level of the skin. Abrasions are most commonly caused by friction injuries, falling off bikes is a common cause. These wounds need to be well cleaned to remove dirt and grit which may be sticking to the wound surface.
Cured egg yolks are the mysterious, and slightly strange homemade condiment that everyone should be making. For something as fancy sounding as it is, the recipe itself is extraordinarily simple. Little salt, little sugar, and some patience. Put that stuff on EVERYTHING.
Josh Kilmer-Purcell and Brent Ridge, co-founders of Beekman 1802, step into the Miele Demonstration Kitchen at the Mercantile in Sharon Springs, NY to demonstrate how to preserve egg yolks and how to use them in your kitchen.
