NIH-funded study reveals how differences in male and female brains emerge
Nematode worms may not be from Mars or Venus, but they do have sex-specific circuits in their brains that cause the males and females to act differently.

Discovery shows how herpes simplex virus reactivates in neurons to trigger disease
When we get cold sores, the reason is likely related to stress. In particular, the neurons in which the herpes simplex virus (HSV) reside, are under stress. For the first time, researchers at the University of North Carolina School of Medicine discovered a cellular mechanism that allows the virus to reactivate. They also found how brain cells are duped into allowing bits of virus to escape the very repressive environment in neurons and cause disease. HSV is found in about 90 percent of the...

GİBERELLİNLER : Bitki Boyu Düzenleyicileri
Giberellinler Japonya’da 2. Dünya Savaşı yıllarında keşfedilmiştir, fakat bu sırada batı ile ilişkiler kopuk olduğundan batı bu keşfi 1950’lerde öğrenmiştir. Yüzyıl önce, Asya‟daki çiftçiler çeltik tarlalarındaki pirinç fidelerinin aşırı ölçüde boylandıklarını ve ince kaldıklarını gözlediler. Bu durumda, fideler olgunlaşmadan ve çiçek oluşturmadan önce, ince ve cılız oluyor ve bu sebepten dik duramayıp erkenden ölüyordu veya verim...

Alglerin Ekolojik Önemi
Algler, gerek yapisal olarak gerekse de dis görünüsleri bakimindan oldukça farkli görünümdedirler. Yapisal olarak eukaryotik (gelismis hücre tipi) ve prokaryotik (basit yapili hücre tipi) olmak üzere iki büyük gruba ayrilirlar. Buna göre Mavi-Yesil algler göstermis olduklari hücre organizasyonlari bakimindan prokaryot hücre özelligi tasimaktadirlar. Belirgin bir hücre çekirdeginin olmamasi ve çok basit olan kromatofor yapisindaki pigmentlerin dagilimi ve prokaryotik hücre...
