Undergraduate students conduct hands-on research: Soil-dwelling bacteriophages may hold the future of medicine, honor President Daniels

At Purdue University, undergraduates get to get their hands dirty in the lab. Metaphorically, of course – their hands and labs are clean, but their understanding of the in-depth complexities of the research process as an organic and opportunistic process is richly rooted in lived experience. Even during the pandemic, students and their professors adapted to ensure that students continued to get hands-on practice, discovering new, potentially therapeutic viruses.

Physicists discover method for emulating nonlinear quantum electrodynamics in a laboratory setting

On the big screen, in video games and in our imaginations, lightsabers flare and catch when they clash together.That clashing, or interference, happens only in fiction – and in places with enormous magnetic and electric fields, which happens in nature only near massive objects such as neutron stars. Physicists have discovered that it is possible to produce this effect in the laboratory using a class of novel materials

Purdue scientist helps guide the eyes of soon-to-launch Webb Space Telescope, successor to Hubble

The sight of the stars the first time he peered into a telescope floored Danny Milisavljevic. There, right before his eyes, was an entire universe full of planets and details, unexplored and unexpected. Now an assistant professor of physics and astronomy in Purdue University’s College of Science, Milisavljevic is helping bring details from the world’s newest and most powerful telescope: the James Webb Space Telescope, the successor to the Hubble Space Telescope, which allowed humans to see farther into space and deeper into time.

Training computers to tease out the subtext behind the text

It is hard enough for humans to interpret the deeper meaning and context of social media and news articles. Asking computers to do it is a nearly impossible task. Even C-3PO, fluent in over 6 million forms of communication, misses the subtext much of the time. Natural language processing, the subfield of artificial intelligence connecting computers with human languages, uses statistical methods to analyze language, often without incorporating the real-world context needed for understanding the shifts and currents of human society. To do that, you have to translate online communication, and the context from which it emerges, into something the computers can parse and reason over.

Researchers study the link between vitamin D and inflammation

An active metabolite of vitamin D—(not the over-the-counter version) — is involved in shutting down inflammation, which could potentially be beneficial in patients with severe COVID-19. Previous studies have shown vitamin D’s ability to reduce the inflammation caused by T cells — inflamed cells in the lung characteristic of the most severe and dangerous cases of COVID-19. But as important as understanding that a drug works is understanding the how and the why. This is both to maximize benefit and minimize harm (such as preventing people from eating livestock dewormer or injecting household cleaners into their veins) as well as to pave the way for future treatments.

Black-Footed Ferrets: Top Milestones for a Species Once Presumed Extinct

Black-footed ferrets, North America’s only native ferret species, were thought to have gone extinct in 1979. On Sept. 26, 1981, a black-footed ferret was discovered on the Wyoming prairie. From that unlikely occurrence, an entire species began its comeback — one of the most remarkable conservation stories on Earth. In honor of the 40th anniversary of the discovery of the last black-footed ferret colony, here are five of this miraculous species’ momentous conservation milestones.

Putting a price tag on the priceless: Real-world property values in Kenya aid conservation decisions

Wildlife is priceless, but wildlife conservation is far from free. Being able to assess the value of land is vital to the success of land conservation. In an effort to bolster this understanding, a Kenyan ecologist, Peter Tyrrell of the University of Oxford and the South Rift Association of Landowners, turned to data science methods to mine data from real estate websites to determine how land is valued across Kenya.

Farm-dwelling Tree Swallows are Feeding Their Chicks Pesticide-laced Prey

On agricultural landscapes, pesticides travel through food webs and can negatively affect local wildlife populations. However, few studies have considered the long-term, cumulative effect of multiple pesticides on avian species, and most are carried out with treated food in a laboratory setting, not in the living landscape. Other studies have analyzed pesticides in the soil and water, but not in the food web itself.

Soaking Up the Sun: Artificial photosynthesis promises a clean, sustainable source of energy

Humans can do lots of things that plants can’t do. But plants have one major advantage over humans: They can make energy directly from the sun. That process of turning sunlight directly into usable energy – called photosynthesis – may soon be a feat humans are able to mimic to harness the sun’s energy for clean, storable, efficient fuel. If so, it could open a whole new frontier of clean energy.

A Sticky Subject: Studying shellfish for advanced adhesives

Humans have been trying to stick things to other things for millennia. But shellfish have been doing it for eons longer. And they are far better at it than humans. Which is why Purdue chemists got to wondering: Why don’t we just use whatever they’re using? Anyone who has ever tried to unstick a barnacle from a rock knows that it’s nearly impossible. That success is something Jonathan Wilker, a Purdue professor of chemistry and materials engineering, and his lab are hoping to learn from – and build on.
