- Fossil of oldest beaked bird found (Seattle Times 6/17)
- "Paleontologists have found a fossil of the oldest-known bird species with a beak - an upturned bill resembling Woody Woodpecker's. The 130-million-year-old, crow-sized Confuciusornis dui was discovered last year in ancient lake sediment in China, so exquisitely preserved that impressions of its feathers are clearly visible. Previously, the earliest known toothless, beaked bird dated from about 70 million years ago."

- New Insight On The Plains' Biggest Rains -- Rocky Mountains Affect Midwest Flooding (Science Daily 6/16)
- "Until now scientists have found it hard to predict which summer storms forming over the Rocky Mountains would produce giant, flood-prone storm systems in the Great Plains to the east. Now Andrew Crook (National Center for Atmospheric Research, or NCAR) and Donna Tucker (University of Kansas) may have found the key: the strength of intense downdrafts that emerge from the mountain storms and stir up severe weather downstream."
- Nebraska Education Officials Stick With Evolution (Yahoo! News 6/12)
- "The Nebraska Board of Education Friday rejected an effort to broaden the science curriculum in state schools in a way that could have allowed classrooms to explore biblically based creation theories.

- Museum Opens 'Temple Of Geology' In New York (Yahoo! News 6/10)
- "The American Museum of Natural History in New York, best known to millions of annual visitors for its stuffed fauna and dinosaur bones, is now into rock and roll. No, not the music. On June 12 it opens the Gottesman Hall of Planet Earth, an extravaganza of sights, sounds and sensations complete with 168 geological specimens and a simulated earthquake."
- Massive Pollution Documented Over Indian Ocean (Science Daily 6/10)
- "An international group of scientists participating in a climate field experiment has documented widespread pollution covering about 10 million square kilometers of the tropical Indian Ocean -- roughly the same area as the continental United States. The finding raises serious questions about what impact the extensive pollution is having on climate processes and on marine life in the ocean below."
- Scientists use balloons as poor man's space shuttle (Seattle Times 6/8)
- "Frustrated by soaring costs, long delays and rocket failures that ruin everything, growing numbers of scientists are reaching for space with a technology that is much cheaper and simpler: balloons."
- Two New Superheavy Elements Discovered (Science Daily 6/8)
- "Discovery of two new "superheavy" elements has been announced by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory. Element 118 and its immediate decay product, element 116, were discovered at Berkeley Lab's 88-Inch Cyclotron by bombarding targets of lead with an intense beam of high-energy krypton ions. Although both new elements almost instantly decay into other elements, the sequence of decay events is consistent with theories that have long predicted an "island of stability" for nuclei with approximately 114 protons and 184 neutrons."

- "Microcystis, a blue-green algae that is harmful to humans and deadly to plants and fish, has returned to a small area of western Lake Erie after a 10-year absence. Researchers are examining whether the reappearance of Microcystis might be associated with the recent arrival of zebra mussels, a non-native species that was introduced to Lake Erie from Russia in 1986."
- UW Scientists Say Arctic Oscillation Might Carry Evidence Of Global Warming (Science Daily 6/3)
- "For years, scientists have known that Eurasian weather turns on the whim of a climate phenomenon called the North Atlantic oscillation. But two University of Washington researchers contend that the condition is just a part of a hemisphere-wide cycle they call the Arctic oscillation, which also has far-reaching impact in North America."
- Scientist questions safety of potential nuclear waste site (CNN 6/2)
- "Signs of ancient groundwater flooding at the proposed Yucca Mountain site for nuclear waste in Nevada could put the project's safety in question, a Russian scientist says. Geologist Yuri Dublyansky of the Russian Academy of Sciences said Tuesday the flooding problem he found may be a "potential show-stopper." Designers of the long-delayed project hope to seal off the radioactive waste underground for 10,000 years or more, when it will have decayed to safer levels."

- "The slow growth rates of calcite and opal minerals that coat fractures and cavities in Yucca Mountain attest to the hydrological stability of that Nevada mountain for the past several million years, according to three U.S. Geological Survey scientists. They presented their views today (June 2) at the spring meeting of American Geophysical Union in Boston."
- Bacteria thrive on simulated Mars (Seattle Times 6/2)
- "An exotic Earth bacterium thrives in laboratory conditions that imitate the environment of Mars, raising fresh hope that the red planet may harbor life, or at least did so in the past, a researcher says. Timothy Kral of the University of Arkansas said a methane-making, oxygen-hating microbe "grows just fine and dandy" in a simulated Martian environment that could not support most forms of life on Earth."
- Huge Black Hole Seen As Probably Center Of Galaxy (Yahoo! News 6/1)
- "Measuring the solar system's orbit around the Milky Way Galaxy has provided more evidence that a ''super-massive'' black hole lies at the galaxy's center, astronomers said Tuesday. Using precise measurements made with an array of radio telescopes, astronomers penetrated the dust that obscures our view and figured that the solar system is circling the galaxy's center at a speed of 135 miles per second, requiring 226 million years for a single orbit."
- The world at 2000: hotter, stormier but with rays of sunshine (CNN 6/1)
- "The world is getting hotter and Mother Nature madder, sperm counts are sinking in the United States and Europe, and the use of wind power is soaring, a millennium-ending snapshot of global trends finds. Worldwatch Institute's annual eclectic compilation of facts and figures, "Vital Signs 1999," offers a little something for everyone making predictions about where the planet and its inhabitants are headed in the next century."
- Cosmic Ray History Encoded In Abundances Of Light Elements (Science Daily 6/1)
