Bring up robot-human relations, and you’re bound to conjure images of famous futuristic robots, from the Terminator to C-3PO. But, in fact, the robot invasion has already begun. Devices and programs, including digital voice assistants, predictive text and household appliances, are smart, and getting smarter. It doesn’t do, though, for computers to be all brain and no heart. Computer scientist Aniket Bera is working to make sure the future is a little more “Big Hero 6” and a little less Skynet.

The standard image of Antarctica is vast, featureless sheets of ice and blowing blizzards. But soaring rocky mountains with deep valleys cut like a knife into the continent of Antarctica, evoking the lavish landscapes of the American Southwest’s Monument Valley. Here, ancient rocks reach for the cold blue sky, and here is where Marissa Tremblay, assistant professor of earth, atmospheric, and planetary sciences at Purdue University, led her team of science experts – all of whom happen to be women.

An imaging agent just approved by the FDA will allow surgeons to identify additional cancerous lesions, which otherwise would have been left behind, in up to 24% more patients during non-small cell lung cancer surgery.

When the rover Perseverance landed on Mars, it was equipped with the first working microphone on the planet’s surface. Scientists have used it to make the first-ever audio recording of an extraterrestrial whirlwind.

Fire ants are a threat that fence lizards never evolved to face. Their typical defense strategy—freezing into place in hopes that the predator goes away—doesn’t work for fire ants. The ants don’t care that the lizard is cleverly blended in; they’re going to bite anyway.

Michelle Thompson is a geologist. But while “geo” means earth, she studies things that are decidedly unearthly, or at least extraterrestrial: the moon and asteroids.

Cancer strikes without warning. Genetics can explain some of it, as well as environmental and lifestyle conditions. But there is no surefire way to predict who will develop cancer. That tragedy holds true for both humans and their closest domestic companions: dogs. A canine cancer scientist at Purdue University’s College of Veterinary Medicine is working to take the first steps to make a serious form of cancer in dogs — one with analogues to human health — easier to detec

What do spaceships, strawberries and vaccines have in common? More than you might think. The short answer is that Purdue University engineer Alina Alexeenko is tinkering with ways to make processes involved in each safer, faster and more effective. The longer answer involves fluid dynamics, the fusion of interdisciplinary science, serendipity and Purdue innovation.

The pyramids of Giza are among the humanity’s most iconic cultural achievements. Archaeologists are now starting to piece together how ancient Egyptians were able to harness their physical environment and the dynamics of the Nile itself to build these incredible monuments.

The tiny bits of plastic that wear off bottles, plastic bags, automotive parts and even cosmetics get into the soil and the water supply. They disrupt chemical cycles, throw off ecosystem health and pollute environments both marine and terrestrial. They eventually also get into the air, where they can damage lungs much more effectively. But for that to happen, they have to be worn away by water or earth and then be launched into the sky by winds. A new study published in Nature Nanotechnology has discovered that a process that happens all over the developed world every day accelerates the airborne dispersal of these micro- and nanoplastic particles, posing a risk to human and environmental health.

In lava caves, threaded below and through the Hawaiian Islands, microbes thrive—bustling, burbling communities of bacteria, microorganisms, and small multicellular organisms.

Chemists discover key to early Earth chemistry, which could unlock ways to speed up chemical synthesis for drug discovery.

Foxes are beautiful, charismatic creatures that enrich any landscape – sometimes quite literally. A study published today in the Ecological Society of America’s journal Ecosphere reveals that trees growing on and around the sites of fox dens, especially long-established fox dens, grow faster than trees without vulpine intervention.

The accepted view of Mars is red rocks and craters as far as the eye can see. That’s much what scientists expected when they landed the rover Perseverance in the Jezero Crater, a spot chosen partly for the crater’s history as a lake and as part of a rich river system, back when Mars had liquid water, air and a magnetic field. What the rover found once on the ground was startling: Rather than the expected sedimentary rocks – washed in by rivers and accumulated on the lake bottom – many of the rocks are volcanic in nature. Specifically, they are composed of large grains of olivine, the muddier less-gemlike version of peridot that tints so many of Hawai'i’s beaches dark green.

The harder you hit something – a ball, a walnut, a geode – the more likely it is to break open. Or, if not break open, at least lose a little bit of its structural integrity, the way baseball players pummel new gloves to make them softer and more flexible. Cracks, massive or tiny, form and bear a silent, permanent witness to the impact. Studying how those impacts affect planetary bodies, asteroids, moons and other rocks in space helps planetary scientists understand extraplanetary geology, especially where to look for precious matter including water, ice and even, potentially, microbial life.

Some of the newest and most exciting discoveries from Mars will be brought to you by the letter L. Roger Wiens, professor of earth, atmospheric, and planetary sciences in the College of Science at Purdue University and an expert in Mars robotics technology, led the team that built SuperCam, one of Mars rover Perseverance’s most innovative and effective tools. Recently, SuperCam used its laser to etch the first letter – L – on the Martian surface to learn more about Mars’ lost magnetic field.

Birds migrate and bees pollinate. Flies just fly around. And get overlooked, mostly. But unbeknownst to most humans, flies also pollinate. And some even migrate.

Most humans are familiar with the notion of being “hangry:” of being so hungry a person becomes irritable, angry, or even unreasonable. Most humans, however, don’t resort to cannibalism. That’s not true for all the animals on the planet.

Star birth, star death, exoplanets, galaxies and a window that looks back to the universe 13.1 billion years ago: That’s what the James Webb Space Telescope (JWST) delivered when it released its first handful of scientific images on July 12. As he has from the beginning, astronomer Danny Milisavljevic watched with fellow astronomers, witnessing the universe unfold before his eyes. “These images were incredible,” Milisavljevic said. “JWST just launched a new era of space exploration. The images pushed the envelope of my understanding – of my ability to even explain what I was seeing. These images reveal all sorts of structures that we have never seen before and led me to ask all sorts of questions that I had never even thought to ask.”

Few birds are as polarizing as house sparrows. Even passionate birders – maybe even especially passionate birders – don’t appreciate their bright eyes, adaptable spirits and omnipresent persistence. But for urban ecologists like Jenny Ouyang, they are the perfect study animal: a way to gain an insight into how birds adapt – or don’t – to human environments.
