Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate.A black hole in the universe is not a solid object,like a planet,but it is shaped like a sphere (球體).Astronomers(天文學(xué)家)think that at the center of a black hole there is a single point in space with infinite(無限的)density(稠密).This single point is called a singularity (奇點(diǎn)).If the singularity theory is correct,it means that when a massive star collapses,all the material in it disappears into the singularity.The center of a black hole would not really be a hole at all,but an infinitely dense point.Anything that crosses the black hole is pulled in by its great gravity.
Although black holes do exist,they are difficult to observe.These are the reasons.
● No light or anything else comes out of black holes.As a result,they are invisible to a telescope.
● In astronomical terms,black holes are truly.For example,a black hole formed by the collapse of a giant star would have an event horizon(視界)only 18 miles across.
● The nearest black holes would be dozens of light years away from Earth.One light year is about 6 trillion(萬億)miles.Even the most powerful telescopes could not pick out an object so small at such a great distance.
In 1994 the Hubble Space Telescope provided evidence that black holes exist.There are still answers to be found,however,so black holes remain one of the mysteries of the universe.

Unlocking the Human Genome(基因組)
1A project to unlock secrets-what scientist could resist that challenge?This is what many scientists are doing as they work on the Human Genome Project.The aim of the project is to decode(破譯)all of the some 100,000 genes in the human body.Scientists are using DNA fingerprinting techniques to do the decoding.
2DNA is the substance found in the chromosomes(染色體)of a cell.A chromosome is a chain of genes.Each gene carries a piece of genetic information.At any one moment in a cell,thousands of genes are turned on and off to produce proteins(蛋白質(zhì)).The challenge for scientists is to find out what role each gene plays in protein production.At some point this decoding will be complete.Then scientists will have a map of an ideal genome,or a picture of the total genetic nature of a human being.The ideal genome is called a consensus(交感)genome.Everything works well in a consensus genome.
3But no one in the world has a consensus genome.Everyone's genome is different from the ideal.These differences are referred to as genetic mutations(突變).Genetic mutations in a person's genome mean that the person has a greater than average chance of suffering from health problems.Some problems are not life-threatening.These would include things like colorblindness,or mild headaches.Other problems are serious,such as heart disease,or cancer.
4It will take years to identify the role of each of the 100,000 genes,The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime.The long-term goal is to have each person live a longer,healthier life.
