Mammal enamel: Toothy analysis IDs vegetation of ancient Nebraska
Welcome to Pocket Science: a glimpse at latest analysis from Husker scientists and engineers. For many who wish to rapidly study the “What,” “So what” and “Now what” of Husker analysis.
What?
Between 18 million and 12 million years in the past, the Nice Plains supported an unprecedented number of hooved mammal species that browsed on leafy vegetation — as much as thrice greater than in any trendy ecosystem, together with the densest rainforests. That variety, ecologists figured, might solely have emerged in a panorama equally blanketed with woody, foliage-rich vegetation that employed a type of photosynthesis, C3, favored by roughly 85% of plant species.
However some latest research have hinted that the Nice Plains may very well have featured extra open, savanna-like swaths topped by grasses that will later come to dominate the area. These grasses developed a water-saving type of photosynthesis often known as C4.
So what?
Nebraska’s Willow Nguy and Ross Secord sought to make clear the confusion by turning to tooth — particularly, the quantity of a selected carbon atom, or isotope, discovered within the enamel of fossilized choppers. The C3 and C4 crops produce differing quantities of the carbon-13 isotope, which accumulates and is preserved within the enamel of herbivores consuming these crops. That enamel turns into a mineralized report of the vegetation protecting a panorama thousands and thousands of 12 months in the past.
After analyzing the enamel of 183 tooth from a consultant pattern of extinct mammal species, Nguy and Secord concluded that the Nebraska of 18 million to 12 million years in the past resembled a reasonably dry savanna or woodland peppered with denser forests. Carbon-13 concentrations and the sheer number of hooved mammal species means that even these open expanses featured extra flowering, leafy crops than the grassland-rich Nebraska of in the present day, the researchers stated. Nonetheless, a year-round rising season might have allowed some species to subsist on sparser vegetation.
Now what?
Refining the mannequin that knowledgeable the workforce’s estimates might assist reconcile a disparity between the quantity of C4 grasses on historical landscapes and the surprisingly restricted consumption of that vegetation, Nguy stated.

High-speed chase in central Nebraska ends in crash and arrest
LINCOLN, Neb. (KLKN) — An Illinois man was arrested Tuesday after a high-speed chase in central Nebraska.
About 10:15 a.m., a trooper saw an SUV going 125 mph on Interstate 80 near Kearney, according to the Nebraska State Patrol.
The driver refused to pull over, the patrol said, so the trooper gave chase.
The SUV got off I-80 at the Kearney interchange and headed south on Highway 44, authorities said.
The chase continued for several miles to the intersection with Highway 6/34, where troopers said the driver — 23-year-old Elias Areyzaga — ran a stop sign.
Areyzaga then crossed railroad tracks at a high speed, lost control and crashed in a field, the patrol said.
He was arrested and taken to a Kearney hospital to be checked out.
Areyzaga was then booked into the Buffalo County Jail on suspicion of flight to avoid arrest and willful reckless driving.

Rural Nebraska hospitals plead for higher reimbursement, say some are at risk of closing
LINCOLN, Neb. (KLKN) – For many rural hospitals in Nebraska, the challenge isn’t just providing care; it’s staying open.
They said at a press conference Tuesday that they’re facing a financial crisis and struggling to meet the needs of their communities.
In rural Nebraska, a single hospital is often the only source of care for miles.
But they are facing a tough battle as they deal with a shortage of funds.

They said large urban hospitals such as the University of Nebraska Medical Center receive higher reimbursement rates from insurance and government programs, while smaller rural hospitals are left to scramble for resources.
“We need to make sure that reimbursement models are fair, and they bring dollars to the table for the services that we do have,” said Arlan Johnson, CEO of Howard County Medical Center.
Sen. Brian Hardin said as health care costs rise, the financial gap only widens.
“In 2023, the average retail value of a Tier 4 drug in America was $257,000 for the year,” he said. “Who can afford that? Short answer, no one.”
He wants to make sure rural hospitals can participate in the 340B program, which allows them to purchase drugs at a discount.
“In order to give top-notch care and provide extra services in the community we have, we have to ensure that Medicaid and 340B programs are protected,” said Laura Gamble, CEO of Pender Community Hospital.

Health officials said if rural hospitals don’t get higher reimbursement, some will have to close.
For families living in remote areas, those closures mean longer drives to receive basic care and, sometimes, delayed treatment.
State leaders are aware of the challenges and said it’s one of their top priorities this upcoming legislative session.
But the solutions are far from simple.
Sen. Mike Jacobsen of North Platte said this upcoming year, he plans to work with the Nebraska Medical Association to work on a bill that would allow higher reimbursement for doctors and other practitioners.
Hardin said Congress needs to step up and remodel 340B.

LIVE: Nebraska hospital leaders to highlight critical health care issues, call for policy action
LINCOLN, Neb. (KOLN) – The Nebraska Hospital Association (NHA) and the Nebraska Rural Health Association (NeRHA) will provide an overview of the 2025-26 Roadmap to Strong Rural Health Care during a press conference on Tuesday at 10:30 a.m.
The NHA and NeRHA will be joined by Nebraska hospital leaders and state senators to highlight state and federal issues important to the future of rural health care in the state.
You can watch the news conference when it begins in the video player above.
Rural hospitals make up about 35 percent of all hospitals nationally, and over 68 percent of hospitals in Nebraska, according to a joint press release from NHA and NeRHA. More than 41 percent of those are at risk of closure.
In addition, Nebraska has more rural residents living at least 25 minutes away from an ambulance than all but two other states. About 16 percent of Nebraska mothers must travel at least 30 minutes to find a maternal care provider, about twice the national rate, and more than half of Nebraska’s counties are considered maternity deserts.
NHA and NeRHA said 85 of Nebraska’s rural communities are considered medically underserved areas for primary care services alone. Projections show that Nebraska will experience a workforce shortage of over 5,000 nurses in 2025.
