VOICE TWO:
And this is Bob Doughty with Science in the News, a VOA Special English program about recent developments
in science. Today, we tell about problems in medical reporting. We tell about the use of a drug that makes
baseball players stronger. And we tell about powerful ocean storms called hurricanes.

VOICE ONE:
The Journal of the American Medical Association --JAMA --is one of the world’s leading medical
publications. It provides reports on the latest developments in medicine. This month, the magazine examined the
way it and other medical publications do their work. It discovered problems in the quality of information
produced by the publications.
One JAMA report found that published studies often use numbers that make experimental
drugs or treatments look better than they really are. The report said some of the problem is
caused by conflicts of interest among scientists.
VOICE TWO:
Medical publications use a system called “peer review.
”
Under this system, scientists
write a report about their research and send it to a medical publication. The editor of the
publication sends the report to other medical experts for advice. Those experts check for
mistakes and make suggestions that the editor uses in deciding to publish the report or
reject it. However, there may be conflicts of interest among scientists doing similar research.
VOICE ONE:
Catherine DeAngelis is editor of the Journal of the American Medical Association. She said problems were most
likely to happen in research paid for by drug companies. Drug companies are interested in findings that make
their products look good.
Editors of medical publications are concerned that drug companies sometimes influence how researchers report
study results and may even suppress some findings. Many top medical publications require researchers to tell if
they have any ties to drug companies. Editors at these publications depend on researchers to be honest about such
ties. But that does not always happen.
VOICE TWO:
In another report in JAMA, the editor of The Lancet studied ten medical research reports published in his
magazine. He found that some of the writers did not include critical comments from other people involved in the
research. He said disagreements among researchers about a study’s findings happened often but were not
always included in the reports.
Another report in JAMA criticized medical publications for the information they provide to newspapers and other
media. Most publications prepare press releases about studies they publish.
These press releases are written to increase the chance that newspapers will publish stories about the studies. Two
American doctors examined more than one-hundred press releases from JAMA and six other medical
publications. They found that press releases often lacked important information, such as limitations of the study
or that a drug company paid for the study.
VOICE ONE:
JAMA also dealt with the issue of reporting about medical research presented at scientific conferences. It said the
media often report about this research even though the research may not be completed. Sometimes the research
findings are later found to contain mistakes. The media often present early research results to the public as
scientifically correct evidence when this may not be true.
Critics are concerned that findings presented in medical publications and other media are not always correct.
Doctor DeAngelis said the special issue of JAMA is an attempt to examine medical publications and to make
sure they are as correct and honest as possible.

VOICE TWO:
Drugs called anabolic steroids are back in the news. Anabolic steroids increase the size and strength of muscles.
Ken Caminiti, a former baseball player, admitted last month that he used steroids. Caminiti told Sports Illustrated
magazine that he took the drugs to improve his performance in nineteen-ninety-six. That is when he was named
the Most Valuable Player in North American baseball’s National League.
Caminiti and another recently retired player say that steroid use is common among
professional baseball players. Their comments have caused much discussion
throughout the United States.
VOICE ONE:
Steroids are products of the male hormone testosterone. A normal adult male
produces between two and eleven milligrams of testosterone a day. A steroid user takes more than one-hundred
milligrams a day.
Side effects of steroid use can include heart and liver damage, stroke, high blood cholesterol levels, aggression
and disorders of the reproductive system. In young people, steroids can affect the bones, limiting a person’
s
height.
VOICE TWO:
In the United States, anabolic steroids are illegal, unless a doctor advises their use for health reasons. The
National Football League and National Basketball Association ban steroids. They test players to make sure they
are not using the drugs. The International Olympic Committee also bans the drugs. Major League Baseball,
however, has no policy on steroids and does not test players for the drugs. Yet baseball’s top administrator
admits that steroids are a problem.
A ban on steroid use in baseball would have to be negotiated as part of an agreement between team owners and
the players. Some players say they want testing for steroids. Others say that would be an invasion of their privacy
rights.
Ken Caminiti is recovering from problems with alcohol and illegal drugs. He says steroids made him bigger and
stronger. Yet he admits that he now suffers side effects from using the drugs.

VOICE ONE:
Early every summer, weather scientists in North America prepare for a new season of powerful ocean storms.
These storms are called hurricanes. The word “hurricane”
comes from the language of people who lived on
islands in the Caribbean Sea before Europeans arrived. They experienced strong ocean storms usually caused by
weather movements off the coast of North Africa. These weather events gather force as they move west toward
the Caribbean and North America.
A storm is called a hurricane when its wind speed becomes greater than one-
hundred-twenty kilometers an hour. Some huge storms cause great loss of life and
thousands of millions of dollars in damage.
VOICE TWO:
Understanding the movements of storms and hurricanes is the job of the National
Hurricane Center in Miami, Florida. Today, many electronic tools make the job of
weather scientists, or meteorologists, easier. Satellites observe weather from space.
New radar instruments gain information about weather movements. And, airplanes
can drop special instruments into storms that record large amounts of information about air movements.
One computer program, called Hurritrack, permits meteorologists to see all the information about weather that
the National Hurricane Center collects.
VOICE ONE:
The National Oceanic and Atmospheric Administration has estimated the number of hurricanes for each year
since nineteen-ninety-eight. This year, NOAA expects six to eight hurricanes and nine to thirteen powerful
Atlantic Ocean storms. Hurricane season in the Atlantic Ocean lasts from the beginning of June to the end of
November.
Also, a weather event called El Nino will affect storms forming in the Atlantic Ocean this year. El Nino is caused
by unusual warm currents of water in the eastern Pacific Ocean. It affects weather around the world.
VOICE TWO:
In nineteen-ninety-seven, El Nino caused storms, floods and severe weather that were blamed for more than
twenty-thousand deaths. NOAA expects this year’s El Nino to be weaker than in past years. Yet, meteorologists
warn that this year’s hurricane season could be severe.
Mike Black is the field director of the Hurricane Research Division of NOAA. He says that hurricanes remain a
mystery to meteorologists even though they have more tools to study them than ever before. He says the complex
forces that cause hurricanes to grow in strength are still not well understood. Meteorology still cannot tell us what
weather events like hurricanes will do in the future.
