Are We in the Midst of a Sixth Mass Extinction?
Katarina Zimmer | Jul 18, 2022 | 10+ min read
Today’s extinction rates are sky-high. But scientists debate if that’s sufficient evidence to conclude that Earth is undergoing a mass extinction event—or whether that’s even a helpful designation.

Animal Divorce: When and Why Pairs Break Up
Catherine Offord | Jun 1, 2022 | 10+ min read
Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.
Elemental Shortage
Brendan Borrell | Nov 1, 2010 | 10+ min read
By Brendan Borrell ELEMENTAL SHORTAGE The world is running out of cheap phosphorus, the element that lies at the heart of great agricultural advances and thorny environmental problems. Biologists are only now beginning to understand what it means for evolution and human health. James Elser at a study site in southern Norway Although a limnologist in Phoenix and a molecular biologist in Atlanta have never met before, a single element ties them together.
How to Create a Successful Fish Tale?
A. J. S. Rayl | Aug 19, 2001 | 10+ min read
More than 80 percent of the planet's living organisms exist only in aquatic ecosystems. Some may harbor secrets to human origins, and clues, treatments--perhaps even cures--for human disease. Some are critical bioindicators that portend the health of the biosphere. Yet, overall, scientists know little about the biochemical processes of these life forms. The vast, rich knowledge within the oceans and freshwater systems on Earth remains virtually untapped, because in the world of biological resear
The Great Haddock Revival

By Kirsten Weir The Great Haddock Revival In the near-empty seas, one species has surged back to life. Can the others follow? Photography by Alexandra Daley-Clark filmy, pink dawn has just slipped above the horizon as the F/V Stormy Weather arrives at the fishing grounds. After a two-hour cruise from port in Hampton Beach, NH, the vessel has reached the southwest corner of Jeffrey's Ledge, a winding offshore glacial
Future Studies Of Pathogens Depend On Conserving Microbes
Joshua Lederberg | Mar 16, 1997 | 7 min read
The conservation of biodiversity is a universally applauded good, bringing to mind the aesthetic values of elegant felines and brilliantly plumaged birds. The rain forest and other plants have also been the source of many important pharmaceuticals, which can be assessed for their economic and health-giving powers. We need but mention familiar examples like quinine and aspirin (and we cannot ignore morphine and cocaine-albeit opium poppies and coca bushes are in no danger of extinction). We shou

All's Well that Ends Well: A Profile of Specialty Microwell Plates
Brent Johnson | Sep 26, 1999 | 10+ min read
Date: September 27, 1999Table of Specialty Microplates The story of the microplate is one of those tales of history that either has been forgotten or was never clearly understood. According to Barry Lazar of Dynex Technologies, formerly Dynatech Laboratories, the origin of what is now commonly referred to by Dynex's registered trademark of Microtiter plates began with Gyola Takatsy, a Hungarian-born scientist who was trying to scale down serology tests. His first prototype became available in 1
Genetic Parasites and a Whole Lot More

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
