Citizen Scientists Enhance New Europa Images from NASA’s Juno

Researchers find Link between Immune Cells’ Closest Neighbors and Survival Time in Patients with Pancreatic Cancer

Researchers from Johns Hopkins Medicine have discovered that the organization of different types of immune cells within pancreatic tumors is associated with how well patients with pancreatic cancer respond to treatment and how long they survive. The new findings, published Sept. 16 in Cancer Research, could eventually lead to new ways of treating pancreatic cancer, which has the highest mortality rate of all major cancers.

“Mapping the location of certain immune cells associated with a tumor could be a new biomarker to predict patient survival,” says Aleksander Popel, Ph.D...

The Battery that Runs 630km on a Single Charge

A research team succeeds in developing anode-free Li batteries with maximized energy density, improving energy density by 40%. The number of newly registered electric vehicles (EVs) in Korea surpassed 100,000 units last year alone. Norway is the only other country to match such numbers. The core materials that determine the battery life and charging speed of now commonly seen EVs are anode materials. Korea’s domestic battery industry has been committed to finding revolutionary ways to increase the battery capacity by introducing new technologies or other anode materials. But what if we get rid of anode materials altogether?

A POSTECH research team led by Professor Soojin Park and PhD candidate Sungjin Cho (Department of Chemistry) in collaboration with Professor Dong-Hwa Seo and Dr...

Impact that Killed the Dinosaurs Triggered ‘Mega-Earthquake’ that Lasted Weeks to Months

66 million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs. New evidence suggests that the Chicxulub impact also triggered an earthquake so massive that it shook the planet for weeks to months after the collision. The amount of energy released in this mega-earthquake is estimated at 1023 joules, which is about 50,000 times more energy than was released in the magnitude 9.1 Sumatra earthquake in 2004.

Hermann Bermúdez will present evidence of this “mega-earthquake” at the upcoming GSA Connects meeting in Denver this Sunday, 9 October...
