From animal studies, researchers in the U.S. and Israel know that some odors are detected more easily when they're flowing past nasal tissue quickly, and others when they' re moving slowly.

However, during the next 10 years, doctors will be given tools for detecting the earliest stages of many cancers, in some cases when they are only a few cells strong-and suppress them before they have a chance to progress to malignancy.

Researchers now know that some species have a magnetic sense, which might allow migrants to determine their geographic location by detecting variations in the strength of the Earth's magnetic field.

The immunological method of detecting peptide hormones by means of antiserums, however, is imprecise.
但是,通过抗血清的手段来测定肽激素的这种免疫学方法(immunological method)有失精确。

Cross-reactions are possible and this method cannot determine whether the substances detected by the antiserums really are the hormones, or merely close relatives.

Furthermore, this method cannot be used to determined the location in the body where the detected substances are actually produced.

The molecular approach to detecting peptide hormones using cDNA probes should also be much faster than the immunological method because it can take years of tedious purifications to isolate peptide hormones and then develop antiserums to them.

Particles created in this way have only a fleeting existence; they are annihilated almost as soon as they appear, and their presence can never be detected directly.

They are called virtual particles in order to distinguish them from real particles, whose lifetimes are not constrained in the same way, and which can be detected.

Astronomers have detected the brightest explosion ever witnessed in the heavens. It was a flash of light from across our galaxy so powerful that it bounced off the Moon and illuminated Earth's upper atmosphere. The researchers say if the blast had occurred closer to Earth, it might have lead to the death of much of the planet's life.

Disorders of psychological development
The disorders included in this block have in common: (a) onset invariably during infancy
or childhood; (b) impairment or delay in development of functions that are strongly
related to biological maturation of the central nervous system; and (c) a steady course
without remissions and relapses. In most cases, the functions affected include language,
visuo-spatial skills, and motor coordination. Usually, the delay or impairment has been
present from as early as it could be detected reliably and will diminish progressively as
the child grows older, although milder deficits often remain in adult life.
