Pharmacokinetic studies live and die by the quality of their blood samples. To trace how a drug rises, peaks, and clears from the bloodstream, researchers must draw venous blood again and again at precisely timed intervals, and each additional puncture adds burden for participants and risk to the sampling schedule. A new pilot study suggests that a needle-free blood collection device can keep a single intravenous catheter working through an entire day of intensive sampling, potentially reshaping how early-phase drug research is conducted.

Paternity Leave Is More Than a Perk. It Builds a Baby’s Brain
We often treat paternity leave like a company perk—something HR lists next to the gym stipend and the 401k match. The research says we are wrong about that categorization. Paternity leave should be part of routine medical care during this stage of life: interventions we already agree are worth investing in because the return on investment continues years later in a child’s brain.
A chemical produced by gut bacteria may accelerate Alzheimer’s disease
A byproduct produced by certain gut bacteria may directly accelerate the brain changes associated with Alzheimer’s disease. Elevated blood levels of this molecule, known as imidazole propionate, correlate with worse cognitive decline in humans and actively drive neurodegeneration in animal models. The findings were published in Nature Communications.

Imagine losing an arm and simply growing a new one. This amazing ability of regeneration isn’t just something from a superhero movie – it actually happens in real life for some animals.
Salamanders are known as champions of regeneration. If a salamander loses a leg, it can regrow another one, complete with bones, nerves, blood vessels and muscles.
Scientists use bacteria to produce muconic acid from plants
Their findings, recently published in Metabolic Engineering, lay the groundwork for a more environmentally friendly way to produce plastic, textiles, pharmaceuticals and more.
“In order to build a sustainable society, we need to move away from fossil fuels. But what many people don’t realize is that there’s a significant portion of fossil fuels that are not extracted for energy usage, but for chemical manufacturing,” said Anne Lalande, a graduate student in the Department of Microbiology and Immunology at UBC and first author of the study. “We’re interested in using lignin, or wood waste, to make valuable chemicals in order to displace the fossil fuel industry.”
Liberal stronghold set to adopt eye-popping minimum wage amid business exodus

In 2024, scientists dyed Peter Lake blue with Aquashade to starve algae of light, but the water still turned green, and the team suspects repeated rain kept flushing the pigment out.
The lake is Peter Lake, a long-serving subject of one of ecology’s most patient experiments, and the person tipping pigment over the gunwale was Danny Szydlowski, a PhD candidate and CASC graduate fellow at the University of Wisconsin–Madison Center for Limnology, working with a colleague, Dat Ha. Their account of the season, published on the Midwest Climate Adaptation Science Center blog on 22 January 2025, reads less like a triumph than a puzzle: the dye went in, the fertiliser followed, and the water still bloomed.
Advanced optical imaging reveals hidden activity in blood immune cells
“PBMCs can be isolated clinically really easily, and they’re already used in the clinical workflow,” says Melissa Skala of the Morgridge Institute for Research and the University of Wisconsin–Madison, senior author of the study. “So, the question is, what can we get from them that we aren’t already getting?”
Michigan expands EV infrastructure, but access remains unequal, study finds
esearchers from the University of Wisconsin-Madison found that Michigan’s EV policies place significant emphasis on expanding charging infrastructure and increasing EV adoption, but pay less attention to whether low-income residents can afford to participate in this transition.
“Access to an electric vehicle is not just the ability to buy a vehicle. It is access to the entire system that makes using that technology possible,” said Chelsea Schelly, a co-author of the study and professor at the University of Wisconsin-Madison.
Realta, MGE explore building a nuclear fusion power plant in Wisconsin
This summer, Realta announced plans to build a nuclear fusion research facility at the former Oscar Mayer plant in Madison, which company leaders said would create 600 jobs in the area, following a nationwide search of potential locations for the facility.

Scientists build pacemaker battery that might never need replacing again in a lifetime
A pacemaker that never needs a battery replacement could soon become reality, thanks to a device that generates its own electricity from the very heartbeat it regulates. University of Wisconsin-Madison researchers built a nanogenerator small enough to slip inside an existing leadless pacemaker, potentially letting a single implant last a patient’s entire lifetime.
Led by postdoctoral scholar Pengfei Chen under professor Xudong Wang, the team designed the device to fit inside the Medtronic Micra, the most widely used leadless intracardiac pacemaker on the market today.
What can moments of lucidity teach us about Alzheimer’s?
Watching a loved one with Alzheimer’s or dementia slowly lose their cognitive abilities can be heartbreaking. While the person you once knew seems to be slipping away, sometimes people with Alzheimer’s briefly seem like their old selves again. They may remember a long-forgotten name or suddenly regain the ability to have a fluid conversation. What do these moments of lucidity really mean for the progression of the disease? And what implications do they have for those living with the disease, and their caretakers?
This Common Gut-Bacteria Compound May Be Linked to Alzheimer’s Disease
Nearly a decade ago, University of Wisconsin–Madison professors Barbara Bendlin and Federico Rey led research showing that people with Alzheimer’s disease have different communities of intestinal microbes than healthy individuals.
“Since then, we’ve been trying to figure out how this difference in the gut perhaps leads to changes in the brain,” says Bendlin, a professor of gerontology in the UW School of Medicine and Public Health.
UW-Madison veterinary lab in Barron set to receive $19.5-million in renovations and expansion
Wisconsin’s State Building Commission approved roughly $374-million in building projects statewide last week and one of those projects include a nearly $20-million investment in Barron. The University of Wisconsin-Madison Veterinary Diagnostic Lab (WVDL) has been looking to renovate and expand its Barron location for several years. The lab’s current building was constructed in 1992, but since then its grown too small and its labs can no longer keep up with demand.
Stoughton project aims to preserve hemp as part of Hmong traditions
The University of Wisconsin-Madison’s College of Agricultural & Life Sciences recently received a $5,000 grant toward the project.
