a class or breed of animals; a group of individuals having certain characteristics in common, owing to a common inheritance.

race

(rās)
n.
1. A group of people identified as distinct from other groups because of supposed physical or genetic traits shared by the group. Most biologists and anthropologists do not recognize race as a biologically valid classification, in part because there is more genetic variation within groups than between them.
2. A group of people united or classified together on the basis of common history, nationality, or geographic distribution: the Celtic race.
3. A genealogical line; a lineage.
4. Humans considered as a group.
5. Biology
a. A usually geographically isolated population of organisms that differs from other populations of the same species in certain heritable traits: an island race of birds.
b. A breed or strain, as of domestic animals.
6. A distinguishing or characteristic quality, such as the flavor of a wine.
adj.
Of or relating to race; racial: race relations; race quotas.

2 a distinct ethnic group characterized by traits that are transmitted through their offspring.

race

a population that can be distinguished from other populations of the same species by several genetical characteristics such as frequency of particular genes or chromosomal arrangements. For example, in humans, different races have been found to have quite different frequencies of alleles for the ABO BLOOD GROUP locus. see FOUNDER EFFECT.

race

1. a class or breed of animals subordinate to species, i.e. a subspecies; a group of animals having certain characteristics in common, because of a common inheritance.
2. a fenced lane just one animal wide leading to a dipping tank, spray dip, branding chute, drafting gate, etc.

Patient discussion about race

Q. what causes the heart to race so fst it feels like it going to come right out your chest?

A. Too much caffeine or alcohol or food can sometimes cause your heart to race in an erratic way. http://www.sciencedaily.com/releases/2008/01/080111201910.htm Heart rhythm problems (arrhythmias) occur when the electrical impulses in your heart that coordinate your heartbeats don't function properly, causing your heart to beat too fast, too slow or irregularly.

Arrhythmias are common and usually harmless. Most people have occasional, irregular heartbeats that may feel like a skipped, fluttering or racing heart. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms.

In comparison to flash memory, found in flash drives and iPods, racetrack memory is expected to be 100 times cheaper.
Magnetic racetrack memory is designed to replace the hard disk, and it's estimated that it could compete on price since it's very dense - it can store lots of bits of data on a small area of chip, as the information is stored in vertical towers," said another researcher working on the project.
The Racetrack Memory Project's design works with "racetrack" nanowire channels providing the transport of data stored between two magnetic domains.
Now, the Racetrack Memory Project has published a paper in the popular journal - Science - claiming they can precisely control the arrangement of magnetic domains in their racetrack system, where electrical pulses sent along the nanowires can halt rapid moving domains in a billionth of a second, exactly where required.
