November, 1998
Shrapnel from a smoking gun (Nature Science Updates 11/26)
"In a report in Nature Frank Kyte of the University of California, Los Angeles, describes a tiny meteorite that he thinks might be a fragment of the impactor [that killed the dinosaurs 65 million years ago] ­ a 2.5-millimeter shard of shrapnel from the smoking gun."
Last stop for water...? (Nature Science Updates 11/26)
"Nereid, a distant and wayward satellite of the planet Neptune, has water ­ or rather ice ­ on its surface."
"'Volcano Of Fire' Could Be Entering Its Most Dangerous Phase In Nearly A Century (Science Daily 11/25)
"The eruption of Colima volcano -- also known as Volcan del Fuego, or "Volcano of Fire" -- that began on Nov. 20 has produced its first pyroclastic flows that could signal the start of the volcano's most dangerous period since its catastrophic eruption in 1913, a University at Buffalo volcanologist says."
Environmental Engineers Unravel Evaportation Paradox (Science Daily 11/25)
"If global warming is sending temperatures and precipitation up, why are measures of evaporation down? Two environmental engineers have explained the paradox."
Ancient Antarctic Environment Rocked By Volcanic Eruptions (Science Daily 11/23)
"The first evidence of large volcanic eruptions that shook Antarctica around 25 million years ago has unexpectedly been discovered in rock cores retrieved from the seabed as part of an international ocean-floor drilling project in which the National Science Foundation (NSF) is a partner."
Scientist Finds Asteroid Fossil That May Have Caused Global Dinosaur Extinction (Science Daily 11/20)
"The fossilized remnants of an asteroid that may have caused the global extinction of dinosaurs and other species more than 65 million years ago has been found by a National Science Foundation (NSF)funded researcher."
Deep heat under Hawaii (BBC Online 11/18)
UC Santa Cruz Seismologists Detect Origin Of Volcanic Hotspot That Created The Hawaiian Islands (Science Daily 11/19)
"Earth scientists believe they have found the source of the spectacular 'fountains of fire' seen on the volcanic islands of Hawaii. Now a team from the University of California, Santa Cruz (UCSC) believes this plume of rock extends about 2,890km beneath the surface of the Earth. This is right on the edge of Earth's metallic core."
Scientist finds what may be a fossil from dinosaur-killing asteroid (CNN 11/19)
Part of the Dinosaur Killer (ABC News 11/19)
"UCLA scientist Frank Kyte has analyzed a small piece of a fossilized meteorite excavated from the North Pacific Ocean. He said it must have broken off from the asteroid when it shattered on impact, sending it thousands of miles from the asteroid's supposed crash site in Central America."
Playing pool with planets (Nature Science Updates 11/19)
"Hardly a month goes by without the detection of planets orbiting stars other than our Sun. A source of surprise and puzzlement is how, very often, these extrasolar planetary systems differ markedly from our own Solar System."
First Dinosaur Embryo Skin Discovered (Science Daily 11/18)
Nesting in the mud (BBC News 11/17)
""A team of researchers have announced the discovery of a dinosaur nesting ground strewn with thousands of eggs, dozens of which still have unhatched dinosaur embryos inside. In addition to tiny embryonic bones, many of the eggs contain patches of delicate fossilized skin, providing the first glimpse of the soft tissue covering baby dinosaurs."
Bubbling Beneath Continents (ABC News 11/18)
African Landscape Shaped By Single Magma Plume (Science Daily 10/31)
"A single, 500-mile-wide plume of magma rising beneath Africa may have shaped the entire continent. As it pools beneath the continent, it spreads out, having a vast impact."
The Fire Down Below -- Extreme Heat-Loving Organisms May Be Keys To Molecular Evolution And Origin Of Life, New Book Argues (Science Daily 11/17)
"New evidence, discovered in the past decade, now indicates that life on Earth may have originated close to the fire down below. Indeed, hyperthermophiles -- the extreme heat-loving microorganisms that flourish at and above the boiling point of water -- could be a key to unlocking both evolution and the origin of life itself."
Global Warming: Report from Buenos Aires (New Scientist Magazine 11/98)
"Now it's time to start tying up those loose ends. For the first two weeks of November, environment ministers from round the world are meeting in Buenos Aires, Argentina, to draw up the rules to turn the grand gestures of Kyoto into reality."
Hopkins Geologist Reveals Earth's Plumbing (Science Daily 11/14)
"The chance find of large crystals in the rocks of the Dry Valleys of Antarctica may about to topple a fundamental principle of geology."
Discovery Of New Large, Predatory Dinosaur Reported In Science (Science Daily 11/13)
Another Reason The Dinosaur Days Were Scary... (Reuters 11/12)
""Curved claws like giant meathooks and a long, narrow, crocodile-like skull were among the fossil remains of a new genus and species of dinosaur recently excavated in the Ténéré Desert of central Niger."
Rapid Rock Changes Deep Under Fault Lines Can Trigger Repeated Earthquakes (Science Daily 11/13)
"Rock metamorphism and earthquakes may be linked, say three Yale University geologists. Their theoretical study shows that the release of water by rock within fault zones can occur rapidly, in a time frame measured in decades or centuries, rather than eons, and can lead to repeated earthquakes."
Web Site Explores How Climate Changes Affects Human Health (Science Daily 11/10)
"A Johns Hopkinsgraduate student has launched a Web site to distribute the latest research on issues of climate change and human health."
Cosmic Rays May Help Predict Earthquakes (Science Daily 11/9)
"Cosmic rays that cause chlorine-36 to accumulate over time on rock surfaces can be used to date past earthquakes - and may help predict future ones, a University of Arizona research reports today in Science."
New Method Of Dating Past Earthquakes, Assessing Future Ones Discovered (Science Daily 11/9)
"A Vanderbilt University researcher has unearthed a new way of dating earthquakes, providing a more precise timeline for past quakes and allowing for a more accurate way of assessing the probability of future quakes."
Volcanic Mudflows Could Wipe Out Industrial Town In Mexico (Science Daily 11/4)
"Extremely fast-moving volcanic mudflows could inundate and destroy a large part of a key industrial town near Colima volcano in Mexico sometime in the next 10 years, according to researchers at the University at Buffalo."
