Save That Dye!

Wait, save that integrin!

RNF169 flips the repair switch P oulsen et al. describe an enzyme that helps a cell determine which repair method to use on DNA double-strand breaks (DSBs). Unrepaired DSBs can incite genomic chaos, spurring sections of chromosomes to relocate or even vanish. To ensure that doesn’t happen, a cell wraps a molecular bandage around a DSB. Enzymes arrive at the injury and ubiquitylate the surroundi...

INTERHEART: nine factors that could save your life.

No matter where you live, how old you are or what you look like, health researchers have recently discovered that 90% of the most common cardiovascular event, the first heart attack (myocardial infarction), can be attributed to nine modifiable risk factors. The risk factors include: cigarette smoking, an abnormal ratio of blood lipids, high blood pressure, diabetes, abdominal obesity, stress, a...

Superoxide dismutases: active sites that save, but a protein that kills.

Protection from oxidative damage is sufficiently important that biology has evolved three independent enzymes for hastening superoxide dismutation: the Cu- and Zn-containing superoxide dismutases (Cu,Zn-SODs), the SODs that are specific for Fe or Mn or function with either of the two (Fe-SODs, Mn-SODs or Fe/Mn-SODs), and the SODs that use Ni (Ni-SODs). Despite the overwhelming similarities betw...

Can tourism be the catalyst for urban preservation while permitting the continuation of urban culture? Only if local distinctiveness, rather than preserved monuments, is what attracts tourists to an historic region, argues Orba̧sli. The author advocates preservation through a planning-management approach. This approach avoids façadism (i.e., preservation of the physical elements only), and inste...
