Astronomers find a cosmic Titan in the early universe
Astronomers have discovered a titanic structure in the early universe, just two billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance.

3D-printed lithium-ion batteries
Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed a new method to 3D print lithium-ion batteries in virtually any shape.

Moss rapidly detects, tracks air pollutants in real time
Moss, one of the world's oldest plants, is surprisingly in tune with the atmosphere around it. Now scientists report that they have found a simple and inexpensive way to detect air pollutants, specifically sulfur dioxide, in real time based on subtle changes in moss leaves. The discovery could rapidly alert authorities to potentially dangerous alterations in air quality using a sustainable, natural plant sensor.

Taking steps toward a wearable artificial kidney
There just aren't enough kidney transplants available for the millions of people with renal failure. Aside from a transplant, the only alternative for patients is to undergo regular dialysis sessions to clear harmful cellular waste from their bodies. Now, scientists report a new urea sorbent that could accelerate progress toward the development of a lightweight, wearable artificial kidney with the potential to make dialysis more convenient, comfortable and effective.

World Heritage Sites threatened by rising sea levels
In the Mediterranean region, there are numerous UNESCO World Heritage Sites in low-lying coastal areas. In the course of the 21st century, these sites will increasingly be at risk by storm surges and increasing coastal erosion due to sea-level rise.

Selfish people have fewer children and earn less money
What happens to those who behave unselfishly and make sacrifices for the sake of others? According to an interdisciplinary study, unselfish people tend both to have more children and to receive higher salaries, in comparison to more selfish people.

Regulating microglial activity may reduce inflammation in neurodegenerative diseases
A group of investigators is proposing that targeting immune checkpoints -- molecules that regulate the activity of the immune system -- in immune cells called microglia could reduce the inflammatory aspects of important neurodegenerative diseases like Alzheimer's disease, Parkinson's disease and ALS.

Double dust ring test could spot migrating planets
Astrophysicist now have a way of finally telling whether newly forming planets are migrating within the disc of dust and gas that typically surrounds stars or whether they are simply staying put in the same orbit around the star.

Plant hormone makes space farming a possibility
With scarce nutrients and weak gravity, growing potatoes on the Moon or on other planets seems unimaginable. But the plant hormone strigolactone could make it possible, plant biologists have shown. The hormone supports the symbiosis between fungi and plant roots, thus encouraging plants' growth -- even under the challenging conditions found in space.
