Wildlife Conservation Society researcher develops a new trawl net that drastrically reduces the number of undersized fish caught in the high-volume commercial pollock fishery -- the world's largest trawl fishery. In the U.S. alone, pollock catches $6 billion in 1994. This new net will affect this industry with in the next year.
Johns Hopkins chemist David Draper says he works in an "RNA world." He considers DNA "this monotonous double helix," and has chosen instead to focus on the multi-folded, complex, and important shape and structure of RNA.

National tax reform may have a substantial impact on the environment as well as on economic growth, researchers at Resources for the Future and Stanford University suggest. They have recently launched a study of the environmental implications of three alternative tax plans -- the flat tax, the national sales tax, and the unlimited savings account tax -- now under discussion in Congress.
A University of Minnesota entomologist has found that a line of "hygienic" bees can defend their hives against the huge Varroa mite and also against two common honeybee diseases, a finding that spells hope in the face of a 100 percent Varroa infestation rate in hives nationwide. The work is published in the current Apidologie.
ASME International (American Society of Mechanical Engineers) is contributing 12 technical sessions and symposia at National Manufacturing Week, to be held March 10-13, 1997, in Chicago, Ill. The sessions will explore energy conservation, asset management, problem solving and other issues impacting the safety, reliability and maintenance of plant facilities and their systems. Speakers include members of the ASME Plant Engineering and Maintenance Division.
Dr. John Lienhard, the MD Anderson Professor of Mechanical Engineering and History at the University of Houston, invites those attending Energy Week to travel with him down "The Highways of the 30's," on Wed., Jan. 29, at 6:00 p.m., at the George R. Brown Convention Center, 3rd Level. An honorary member of ASME International, Dr. Lienhard will describe how engineering advancements in automotive technology, fuels and service have changed our society.
ATHENS, Ga. -- The steady warming of the Earth's atmosphere, along with increased concentrations of carbon dioxide, could one day bring cataclysmic changes to the planet, some scientists believe. They have suggested global warming could cause anything from the widespread elimination of species to the melting of polar ice caps. But new studies in USDA's Southern Global Change Program indicate there is at least one hidden advantage to increased CO2 concentrations: much better tree growth due to improved photosynthesis.
Beginning early January, a new FAA/NCAR system being demonstrated at LaGuardia and O'Hare airports will provide snowfall "nowcasts" up to 30 minutes in advance for participating airlines to help reduce takeoff delays, increase safety, and save money on deicing procedures. United, USAir, and Delta are testing the new system.
More than 500 space technology scientists from around the world are expected to attend the University of New Mexico Space Technology and Applications International Forum scheduled for Jan. 26-30 at the Hyatt Regency in Albuquerque, NM.
A Johns Hopkins engineer has developed "magnetic tweezers," a joystick-controlled device he uses to grab and manipulate single molecules of DNA. He is developing the device for such uses as non-invasive transportation of medicine through a patient's veins directly to diseased cells.
Experiments with hamsters show that exposure to bright light blocks the effects of serotonin in the brain, acording to a letter in Thursday's Nature.
The benefits of Redux (d-fenfluramine) don't outweigh the risks, according to Cornell University nutritionist David Levitsky,who has examined the 40 studies on long-term use of the diet pill. "People do lose weight more easily with than with a placebo, but the advantage of taking the medication over a placebo after a year is less than 5-and-a-half pounds."
The 12-state Northeast was sopping, soggy, soaked and sodden as the region sloshed its way to the wettest year in more than a century -- 102 years of official records -- with 53.89 inches of precipitation. This easily broke the old record set in 1972 by 2.55 inches, according to the Northeast Regional Climate Center at Cornell University.
Concerned that raccoon rabies could infect wildlife and humans, Canadian authorities are reaching across the border to help support oral vaccination programs in Northeastern states by veterinarians and wildlife biologists from the Cornell University College of Veterinary Medicine.
Men and women taking selenium supplements for 10 years had 41 percent less total cancer than those taking a placebo, a new study by Cornell University and the University of Arizona shows. This is the first double-blind, placebo-controlled cancer prevention study with humans that directly supports the thesis that a nutritional supplement of selenium, as a single agent, can reduce the risk of cancer
A relatively new theory that may better enable scientists to predict the effects of pollution and contamination on the environment will be discussed at a symposium at the University of Georgia's Savannah River Ecology Laboratory from Jan. 20-23.
It is one of those last gorgeous days of October, and John Fellman is leading me through the variety block of WSU's Tukey Orchard, 392 trees of 97 different varieties. The tastes are doing extraordinary things to my nose and taste buds. We are in apple heaven.
Review copies are available of a new Johns Hopkins University Press book on biodiversity. "The Idea of Biodiversity: Philosophies of Paradise" examines the concept of biodiversity, its origins and its impact on society.
A small gold oven sent to Russia's MIR space station may give scientists valuable insights into diffusive transport in liquids, a fundamental physical process that is so little understood that there are a half dozen conflicting theories about how the process actually works.
A process that bonds the stuff from which bones are made onto the surface of artificial bone and joint implants may give longer life to as many as 600,000 implants a year.
More than 75,000 people become crime suspects each year in the United States based on being identified from lineups and photo spreads. Some identifications will be false and lead to mistaken arrests and imprisonments.
A Johns Hopkins discovery that certain proteins interacting with RNA or DNA have nearly identical shapes and function similarly came as a surprise and may help chemists find more effective antibiotics.
A solvent used in the food-processing trade is expected to help the pharmaceutical industry replace environmentally unfriendly and expensive solvents in the manufacture of drugs. By using supercritical carbon dioxide, or CO2, in the pharmaceutical process, researchers at the University of Kansas have successfully replaced some chemical solvents.
Scientists have recognized for more than a century that some molecules exist as pairs of mirror images. But, are such molecules really righties or lefties, chemically speaking? New research funded by the National Science Foundation is providing an answer.
