'The blob' of abnormal conditions boosted Western US ozone levels
Ozone levels in June 2015 were significantly higher than normal over a large swath of the Western US. Analysis ties this air quality pattern to the abnormal conditions in the northeast Pacific Ocean, nicknamed 'the blob.'

Old rocks, biased data: Overcoming challenges studying the geodynamo
Bias introduced through analyzing the magnetism of old rocks may not be giving geophysicists an accurate idea of how Earth's magnetic dynamo has functioned. A team led by Michigan Technological University shows there is a way to improve the methodology to get a better understanding of the planet's geodynamo.

Flat-footed fighters
Walking on our heels, a feature that separates great apes, including humans, from other primates, confers advantages in fighting, according to a new University of Utah study published today in Biology Open. Although moving from the balls of the feet is important for quickness, standing with heels planted allows more swinging force, according to study lead author and biologist David Carrier, suggesting that aggression may have played a part in shaping our stance.

Tumor-targeting system uses cancer's own mechanisms to betray its location
By hijacking a cancer cell's own metabolism, researchers have found a way to tag and target elusive cancers with small-molecule sugars. This opens treatment pathways for cancers that are not responsive to conventional targeted antibodies, such as triple-negative breast cancer.

New delta Scuti: Rare pulsating star 7,000 light years away is 1 of only 7 in Milky Way
The newest delta Scuti (SKOO-tee) star in our night sky is so rare it's only one of seven identified by astronomers in the Milky Way. Discovered at Southern Methodist University in Dallas, the star -- like our sun -- is in the throes of stellar evolution, to conclude as a dying ember in millions of years. Until then, the exceptional star pulsates brightly, expanding and contracting from heating and cooling of hydrogen burning at its core.

Ventura fault could cause stronger shaking, new research finds
A new study by a team of researchers, including one from UC Riverside, found that the fault under Ventura, Calif., would likely cause stronger shaking during an earthquake and more damage than previously suspected. The Ventura-Pitas Point fault in Southern California has been the focus of much recent attention because it is thought to be capable of magnitude 8 earthquakes. It underlies the city of Ventura and runs offshore, and thus could generate tsunamis.

Extreme temperatures threaten desert songbirds with death by dehydration
According to NASA, 2016 was the hottest year on historical record. Globally, the increase amounted to nearly 1.8 degrees Fahrenheit. And while that might not sound like much of an increase, it could mean the difference between life and death for some bird populations.

Climate change increases lethal dehydration risk in desert songbirds
As the Earth warms from climate change, the risk of lethal dehydration and mass die-offs of songbirds during heat waves will increase in many areas of the world, according to a study by the University of Nevada, Reno, the University of New Mexico and the University of Massachusetts-Amherst published today in the scientific journal Proceedings of the National Academy of Sciences.

Desert songbirds may face expanding threat of lethal dehydration
A new study of songbird dehydration and survival risk during heat waves in the desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advances. Using physiological data, hourly temperature maps and modeling, Alex Gerson at UMass Amherst and others investigated how rates of evaporative water loss varied in five bird species with varied body mass.

Researchers discover a new link to fight billion-dollar threat to soybean production
Invisible to the naked eye, cyst nematodes are a major threat to agriculture, causing billions of dollars in global crop losses every year. A group of plant scientists, led by University of Missouri researchers, recently found one of the mechanisms cyst nematodes use to invade and drain life-sustaining nutrients from soybean plants. Understanding the molecular basis of interactions between plants and nematodes could lead to the development of new strategies to control these major agricultural pests and help feed a growing global population.
