Tigers Take the Night Shift to Coexist with People

EAST LANSING, Mich. – Tigers aren’t known for being accommodating, but a new study in the Proceedings of the National Academy of Sciences indicates that the carnivores in Nepal are taking the night shift to better coexist with humans.

The revelation that tigers and people are sharing exactly the same space – the same roads and trails – of Chitwan National Park flies in the face of long-held convictions in conservation circles. It also underscores how successful conservation efforts need sciences that takes into account both nature and humans.

“As our planet becomes more crowded, we need to find creative solutions that consider both human and natural systems,” said Jianguo “Jack” Liu, the director of the Center for Systems Integration and Sustainability at Michigan State University. “Sustainability can be achieved if we have a good understanding of the complicated connections between both worlds. We’ve found something very interesting is happening in Nepal that holds promise for both humans and nature to thrive.” (more…)

Microbes Help Hyenas Communicate via Scent

EAST LANSING, Mich. — Bacteria in hyenas’ scent glands may be the key controllers of communication.

The results, featured in the current issue of Scientific Reports, show a clear relationship between the diversity of hyena clans and the distinct microbial communities that reside in their scent glands, said Kevin Theis, the paper’s lead author and Michigan State University postdoctoral researcher.

“A critical component of every animal’s behavioral repertoire is an effective communication system,” said Theis, who co-authored the study with Kay Holekamp, MSU zoologist. “It is possible that without their bacteria, many animals couldn’t ‘say’ much at all.” (more…)

Computer Viruses Could Take a Lesson from Showy Peacocks

EAST LANSING, Mich. — Computer viruses are constantly replicating throughout computer networks and wreaking havoc. But what if they had to find mates in order to reproduce?

In the current issue of Evolution, Michigan State University researchers created the digital equivalent of spring break to see how mate attraction played out through computer programs, said Chris Chandler, MSU postdoctoral researcher at MSU’s BEACON Center for the Study of Evolution in Action.

EAST LANSING, Mich. — Soybeans are one of the largest commodity crops in the world.

They also are starting to play a major role in reducing our carbon footprint, providing improved environmental performance and replacing finite, non-renewable resources such as oil.

And this is where Ramani Narayan comes in. (more…)

Two New Owls Discovered in the Philippines

EAST LANSING, Mich. — Two new species of owls have been discovered in the Philippines, and a Michigan State University researcher played a key role in confirming their existence.

The discovery, which is featured in the current issue of Forktail, the Journal of Asian Ornithology, took years to confirm, but it was well worth the effort, said the paper’s lead author Pam Rasmussen, MSU assistant professor of zoology and assistant curator of mammalogy and ornithology at the MSU Museum.

“More than 15 years ago, we realized that new subspecies of Ninox hawk-owls existed in the Philippines,” she said. “But it wasn’t until last year that we obtained enough recordings that we could confirm that they were not just subspecies, but two new species of owls.” (more…)

A Hands-on Approach to Treating Patients with Pulmonary Disease

EAST LANSING, Mich. — Researchers at Michigan State University are working to show how a noninvasive, drug-free form of hands-on medical care can help patients with chronic obstructive pulmonary disease improve their breathing.

The team from MSU’s College of Osteopathic Medicine will apply four osteopathic manipulative treatments to a group of patients with moderate to severe chronic obstructive pulmonary disease. One of the most common lung diseases, COPD typically manifests as chronic bronchitis (a long-term cough with mucus) or emphysema (destruction of the lungs over time). (more…)

Why Do Organisms Build Tissues They Seemingly Never Use?

EAST LANSING, Mich. — Why, after millions of years of evolution, do organisms build structures that seemingly serve no purpose?

A study conducted at Michigan State University and published in the current issue of The American Naturalist investigates the evolutionary reasons why organisms go through developmental stages that appear unnecessary.

“Many animals build tissues and structures they don’t appear to use, and then they disappear,” said Jeff Clune, lead author and former doctoral student at MSU’s BEACON Center of Evolution in Action. “It’s comparable to building a roller coaster, razing it and building a skyscraper on the same ground. Why not just skip ahead to building the skyscraper?” (more…)

Urban Poor Plagued By ‘Burdens of Place’

EAST LANSING, Mich. — Most of America’s urban cores were designed for walking but offer little in the way of supermarkets, healthy restaurants and other amenities for residents to walk to, according to a study led by a Michigan State University scholar.

The study is one of the first to show that poor residents living in declining urban neighborhoods want healthy food choices – evidenced by their willingness to travel long distances to find them. Past research has generally assumed that poor people will shop at whatever store is closest. (more…)
