Nebraska team creates XR experience to reveal life's interconnections
2025-11-13
Imagine existing as an apple tree, stretching your branches toward the sun and sinking your roots into the soil. Imagine life as a prairie dog, digging tunnels among those roots and peeking out to feel the sun’s warmth. Imagine being a robot tractor, planting vegetables beside the tree.
Now, thanks to a team of University of Nebraska–Lincoln researchers and emerging media artists, players can step into all those roles and more through an extended reality (XR) experience that brings science to life.

Researchers reveal intricate control system for key immune gene
2025-11-13
SAN FRANCISCO—The immune system faces a delicate balancing act: it must be aggressive enough to fight infections and cancer, yet restrained enough to avoid attacking the body’s own tissues.
More than two decades ago, researchers identified a gene called FOXP3 as playing a critical role in maintaining this balance and preventing autoimmune disease—work that garnered this year’s Nobel Prize in Physiology or Medicine.
Now, scientists at Gladstone Institutes and UC San Francisco (UCSF) have mapped the intricate network of genetic switches ...
New DNA analysis approach could transform understanding of disease evolution
2025-11-13
Research institutions around the world house valuable genetic information that could help unlock countless medical mysteries. However, because DNA degrades over time, it is difficult for researchers to analyze DNA samples older than 20 years using conventional analytical approaches.
Although modern technologies have transformed researchers’ ability to learn about disease, these technologies have primarily been used on modern genetic samples. The ability to study genetic data from earlier decades has been exceedingly limited, which hinders researchers’ understanding of old diseases and why changes in ...

Arctic fossils reveal complex and diverse Early Triassic marine vertebrate communities
2025-11-13
Just a few million years after the end-Permian mass extinction event (EPME), aquatic reptiles and other vertebrates had recovered to form thriving and diverse oceanic ecosystems, according to a study of an Early Triassic-age fossil site in the Arctic. The findings challenge previous assumptions of a slow and gradual establishment of mid-Triassic marine communities and suggest that vertebrate evolution paralleled the rapid resurgence of invertebrate life in the Early Triassic. The EPME, which occurred roughly 251.9 million years ago (Ma), wiped out upwards of 90% of all marine species on Earth. It has long been thought that recovery of ocean ecosystems following this event was slow, taking ...
Ancient DNA shows dogs joined human migrations and trade
2025-11-13
As human groups migrated and settled across Holocene Eurasia, dogs often traveled with them, researchers report in a new genomic study – and sometimes dogs were traded among populations. The study reveals the integral role these animals played in culture and exchange. For at least the last 11,000 years, dogs and humans have lived side-by-side. However, the true antiquity of their association with humans remains elusive. Some evidence suggests that major dog lineages in different parts of the world appear to have diversified thousands of years earlier, suggesting that these dogs may have traveled with humans as they colonized different parts of Europe, ...
Magnetically guided microrobots for targeted drug delivery
2025-11-13
A magnetically guided microrobotics system is capable of navigating the body’s intricate passageways and vasculature to deliver drugs with pinpoint accuracy, according to a new study. The novel system could enable safer, targeted drug treatments that minimize unwanted side effects. Systemic drug treatments often cause unwanted side effects due to off-target exposure and account for nearly one-third of failures in clinical trials, illustrating the need for precise, targeted drug delivery strategies. To address this, researchers have worked to develop magnetic micro- and nanorobots designed to deliver drugs directly to diseased tissues. Advances in materials ...
Microrobots finding their way
2025-11-13
Every year, 12 million people worldwide suffer a stroke; many die or are permanently impaired. Currently, drugs are administered to dissolve the thrombus that blocks the blood vessel. These drugs spread throughout the entire body, meaning a high dose must be administered to ensure that the necessary amount reaches the thrombus. This can cause serious side effects, such as internal bleeding. Since medicines are often only needed in specific areas of the body, medical research has long been searching for a way to use microrobots to deliver pharmaceuticals to where they need to be: in the case of a stroke, directly to the stroke-related thrombus. Now, a ...
‘Beautiful energy sandwich’ could power next-generation solar and lighting
2025-11-13
Researchers have achieved a new level of control over the atomic structure of a family of materials known as halide perovskites, creating a finely tuned ‘energy sandwich’ that could transform how solar cells, LEDs and lasers are made.
Due to their remarkable ability to absorb and emit light, and because they are cheaper and can be configured to convert more of the solar spectrum into energy than silicon, perovskites have long been touted as a potential replacement for silicon in solar cells, LEDs and quantum technologies.
However, their instability and durability has, so far, largely limited perovskite devices to the laboratory. ...
Which came first: The sponge or the comb jelly? HHMI scientists weigh in
2025-11-13
In the world of phylogenetics, there’s team sponge and team comb jelly.
Which creature roots the animal tree of life — the simple sponge or the more complex comb jelly — has stirred fierce debate among phylogeneticists, researchers who study evolutionary history.
Scientists long assumed the muscle-less and neuron-less sponges gave rise to more complex organisms, including humans. But genomic analyses in 2008 comparing hundreds of genes from many different animals and their relatives delivered ...
