Got Milk? Climate Change Means Stressed Cows in Southern U.S. May Have Less

“Cows are happy in parts of Northern California and not in Florida” is a good way to sum up the findings of new research from the University of Washington, said Yoram Bauman, best known as the “stand-up economist.”

Bauman and colleagues found that the decline in milk production due to climate change will vary across the U.S., since there are significant differences in humidity and how much the temperature swings between night and day across the country. For instance, the humidity and hot nights make the Southeast the most unfriendly place in the country for dairy cows.

Their study combined high-resolution climate data and county-level dairy industry data with a method for figuring out how weather affects milk production. The result is a more detailed report than previous studies and includes a county-by-county assessment — that will be available to farmers — of the impact climate change will have on Holstein milk production in the U.S. through 2080.

The Old Primates’ Club: Even Male Monkeys Ride Their Fathers’ Coattails to Success

Nature

If you’re a male born to a father who’s a strong and enduring community leader, you’re far more likely than your less fortunate peers to become a leader yourself, due to the wide range of social advantages accruing from your dad’s position. (more…)

Making Mirrors for the Sun

Science

With $1.5 million from the Department of Energy, UA researchers are continuing to improve groundbreaking technology to produce solar electricity at a price competitive with non-renewable energy sources.

Just behind the University of Arizona’s Bear Down Gymnasium, a house-sized frame of crisscrossing steel tubes is mounted onto a swiveling post in the concrete bottom of an empty swimming pool. (more…)

Games focused on the environment from Thailand team TANG Thai and math education from U.S. team Drexel Dragons won the two Game Design competitions. (more…)

Diagnostic Technique Uses Immune Cell DNA

Science

By looking at signature chemical differences in the DNA of various immune cells called leukocytes, scientists have developed a way to determine their relative abundance in blood samples. The relative abundance turns out to correlate with specific cancers and other diseases, making the technique, described in two recent papers, potentially valuable not only for research but also for diagnostics and treatment monitoring.

PROVIDENCE, R.I. [Brown University] — When a person is sick, there is a tell-tale sign in their blood: a different mix of the various types of immune cells called leukocytes. A group of scientists at several institutions including Brown University has discovered a way to determine that mix from the DNA in archival or fresh blood samples, potentially providing a practical new technology not only for medical research but also for clinical diagnosis and treatment monitoring of ailments including some cancers.

Jekyll and Hyde Bacteria Aids or Kills, Depending on Chance

Science

EAST LANSING, Mich. — Living in the guts of worms are seemingly innocuous bacteria that contribute to their survival. With a flip of a switch, however, these same bacteria transform from harmless microbes into deadly insecticides. (more…)

“Self-Distancing” Can Help People Calm Aggressive Reactions, Study Finds

Health

COLUMBUS, Ohio – A new study reveals a simple strategy that people can use to minimize how angry and aggressive they get when they are provoked by others.

When someone makes you angry, try to pretend you’re viewing the scene at a distance – in other words, you are an observer rather than a participant in this stressful situation. Then, from that distanced perspective, try to understand your feelings.

Researchers call this strategy “self-distancing.” (more…)

Astronomers Discover Houdini-Like Vanishing Act in Space

Science

Astronomers report a baffling discovery never seen before: An extraordinary amount of dust around a nearby star has mysteriously disappeared.

“It’s like the classic magician’s trick — now you see it, now you don’t,” said Carl Melis, a postdoctoral scholar at UC San Diego and lead author of the research. “Only in this case, we’re talking about enough dust to fill an inner solar system, and it really is gone!”

“It’s as if the rings around Saturn had disappeared,” said co-author Benjamin Zuckerman, a UCLA professor of physics and astronomy. “This is even more shocking because the dusty disc of rocky debris was bigger and much more massive than Saturn’s rings. The disc around this star, if it were in our solar system, would have extended from the sun halfway out to Earth, near the orbit of Mercury.” (more…)
