The science of sensations
Smiling scientist stands in a lab

Ishmail Abdus-Saboor has carved out a path studying the biology of touch, pain, and itch.

The science of sensations

To confront the ills of the opioid epidemic, scientists must develop a fundamental understanding of the biology of pain. Biologist Ishmail Abdus-Saboor’s work is setting the stage for screening alternative drugs and uncovering new pathways that an opioid-alternative could target.

Fruit flies’ microbiomes shape their evolution

In just five generations, an altered microbiome can lead to genome-wide evolution in fruit flies, according to new research led by Paul Schmidt and postdoc Seth Rudman of the School of Arts and Sciences.

Sensors on NASA satellites Terra and Aqua captured a record of thousands of points of fire in Brazil in late August. The fires pose a threat to the Amazon rainforest and to people living in and around it. (Image: NASA Earth Observatory)

Inferno in the rainforest

Satellite images have detected more than 100,000 points of fire in the Amazon this year. Scientists Reto Gieré and Alain Plante illuminate some less obvious impacts of the fires, including health threats and climate impacts.

A molecular ‘atlas’ of animal development
An abstract depiction of data features an elongated shape with various projections in pixels of different colors.

Each cell of a developing nematode worm embryo is catalogued at the molecular level in a new paper out in Science. In this visualization of the dataset, each dot represents a single cell, its color represents the age of the embryo it came from (orange=early, green=mid, blue/red=late), and the dots are arranged so that cells with similar transcriptomes are near each other. Visualized this way, the data form various thin “trajectories” that correspond to tissues and individual cell types. (Image: Cole Trapnell)

A molecular ‘atlas’ of animal development

Scientists have studied the nematode worm Caenorhabditis elegans for decades, making essential contributions to basic science. In the latest milestone, a team uses cutting-edge technology to individually profile the genes expressed in more than 80,000 cells in a developing C. elegans embryo.

Lung cell transplant boosts healing after the flu
Colorful fluorescent labeled cells appear in a tissue sample of a lung

Researchers successfully transplanted a special type of lung cell called AT2 cells (labeled in green) from healthy mice into mice that had experienced a severe flu infection. The AT2 cells that engrafted (in red) appear to have helped the animals recover more robustly. (Image: Aaron Weiner/School of Veterinary Medicine)

Lung cell transplant boosts healing after the flu

A serious case of the flu can cause lasting damage to the lungs. In a study in mice, researchers found that transplanting cells from the lungs of healthy animals enhanced healing in others that had had a severe respiratory infection.

A wearable new technology moves brain monitoring from the lab to the real world

Postdoc Arjun Ramakrishnan (left) and Penn Integrates Knowledge professor Michael Platt created a wearable EEG akin to a Fitbit for the brain, with a set of silicon and silver nanowire sensors embedded into a head covering like the headband seen here. The new technology led to the formation of a company called Cogwear, LLC.

What is a ‘mass shooting’ and how do we talk about gun violence?

In a Q&A, criminologist Richard Berk discusses why definitions matter and what role social media and mental illness play in this context.
