The unprecedented and ongoing climate disasters have put the necessity to decarbonize into sharp relief. In 2021 alone these climate emergencies included a blistering “heat dome” of nearly 50 °C in the normally temperate Pacific Northwest of the United States and Canada, deadly and destructive...

Reducing carbon dioxide using a panchromatic osmium complex photosensitizer

Finding solutions for the current climate and energy crisis has become a common goal across the globe. And why look far when we have the perfect solution right around us? Taking a page out of nature's book, scientists have been trying to recreate the process of photosynthesis to combat climate change. Beyond helping plants prepare their food, photosynthesis also makes them one of the major carbon...

Artificial scaffolds for studying plant cell growth

We cannot see how plants sense force, at least not yet. But a discovery by plant biologists at Washington University in St. Louis will help make it possible to study how mechanical forces, such as gravity, affect the way that plant cells form and grow.

First dinosaur era crab fully preserved in amber discovered

Researchers describe the first crab from the Cretaceous dinosaur era preserved in amber. The study used micro CT to examine and describe Cretapsara athanata, the oldest modern-looking crab (approximately 100 million years old) and the most complete fossil crab ever discovered.

Rediscover trust in cybersecurity

The world has changed dramatically in a short amount of time—changing the world of work along with it. The new hybrid remote and in-office work world has ramifications for tech—specifically cybersecurity—and signals that it’s time to acknowledge just how intertwined humans and technology truly are. Enabling a fast-paced, cloud-powered collaboration culture is critical to rapidly growing...

Citizen scientists help assure quality of coastal biodiversity monitoring

In 2019, history student Rodrigo Gomes found out on social media about a call for volunteers to take part in a scientific project relating to the ocean and conducted by the Federal University of São Paulo's Institute of Marine Sciences (IMAR-UNIFESP) in Santos, on the coast of the state of São Paulo, Brazil. He signed up for the project, took workshops, and trained in the field. "I was very...
