Instead of punching ballots in this summer's primary elections, voters will use new touch screen voting machines. This will be the first time the technologies, touted as more accurate, will be put to the test in official elections. Nationally recognized voting expert Thad Hall is available for comment and analysis.
Construction is accelerating on a $17 million cosmic ray observatory west of Delta, Utah, thanks to two U.S. agencies: the Bureau of Land Management issued a permit, and the National Science Foundation approved a $2.4 million grant.
Atmospheric temperature measurements by satellites indicate Earth's hot, tropical zone has expanded farther from the equator since 1979, say scientists from Utah and Washington state. But they don't know if the tropical expansion was triggered by natural climate variation or by human-caused phenomena such as depletion of the atmosphere's ozone layer or global warming due to the greenhouse effect.
Arctic climate is particularly prone to global warming caused by carbon dioxide and other greenhouse gases. Now, a University of Utah study finds a surprising new way society's pollutants warm the far north: the Arctic's well-known haze "“ made of particulate pollution from mid-latitude cities "“ mixes with thin clouds, making them better able to trap heat.

Humans evolved from ape-like ancestors because they needed to run long distances "“ perhaps to hunt animals or scavenge carcasses "“ and the ability to run shaped our anatomy, making us look like we do today, says a new study from the University of Utah and Harvard University.
University of Utah scientists took early but significant steps to fight a deadly childhood muscle cancer by identifying some genetic events that cause the disease and engineering mice that develop the tumors. The genetic events might be targets for new drugs.
A University of Utah study showing how lice evolved with the people they infested reveals that a now-extinct species of early human came into direct contact with our species about 25,000 years ago and spread the parasites to our ancestors.
University of Utah biologists discovered a gene that allows a plant's roots to tell the leaves to stop growing, presumably when water is scarce, soil is too compacted or other conditions are bad.
A University of Utah experiment conducted in Peru's Amazon Basin shows insects increase the diversity of the rainforest when they munch on trees. Such seemingly destructive behavior keeps dominant tree species under control but allows other trees to thrive.
Even before marble-shaped pebbles nicknamed "blueberries" were discovered on Mars, geologists studied similar rocks in Utah's national parks and predicted such stones would be found on the Red Planet. They believe the Mars and Utah rocks formed in groundwater.
A University of Utah study indicates that genes involved in embryo development must work at both ends of a nerve before the nerve is able to link the brain to each body part it controls.
A powerful earthquake that rocked Alaska in 2002 not only triggered small earthquakes 2,000 miles away at Yellowstone National Park "“ as was reported at the time "“ but also changed the timing and behavior of some of Yellowstone's geysers and hot springs, a new study says.
Meteorologists are using a NASA research jet to examine icy, wispy cirrus clouds high in the atmosphere "“ a study aimed at determining how much the clouds warm Earth's climate and how much they cool it.

Biologists twirled louse-infested bird feathers on an electric fan and flew pigeons and doves like kites on strings in a study that found small lice stick to small birds and big lice prefer big birds. The study also showed why size matters to parasites.
A staggering 98 tons of prehistoric, buried plant material is required to produce each gallon of gasoline we burn in our cars, SUVs, trucks and other vehicles, according to a study conducted at the University of Utah.
A five-year, $3 million study in Panama indicates rainforests can be protected if the pharmaceutical industry establishes Third World laboratories and hires local researchers to look for new medicines extracted from plants that evolved defenses against insects.
Utah and New York researchers have discovered how a gene in the AIDS virus hijacks the human gene and turns it into a weapon that prevents reproduction of immune-system white blood cells, leaving AIDS patients vulnerable to deadly infections and cancer.
University of Utah researchers have identified genes that help explain why mice, people and other mammals evolved with modern rib cages instead of having snake-like ribs that extend from the neck to the tailbone. By disabling the genes, geneticists bred mice with extra ribs that start below the chest's normal rib cage and continue down through the lower back and to the tail.
