A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known example of photosynthesis by living organisms, say University of Wisconsin-Madison geoscientists.
Epidemics of dengue are linked to high temperatures brought by the El Niño weather phenomenon, a University of Florida scientist working with an international team of researchers has found.
New findings have overturned a scientific dogma that stood for decades, by showing that potassium can work with graphite in a potassium-ion battery -- a discovery that could pose a challenge and more sustainable, less costly alternative to the widely used lithium-ion battery.
NASA and NOAA satellites have been watching Hurricane Joaquin move to the northeast through the northern Atlantic Ocean. Although Joaquin is moving away from the US and Canada it is still generating dangerous surf conditions.
A new discovery published in the journal Scientific Reports documents the intricate arrangement of the muscles and ligaments that controlled the main feathers of the wing of an ancient bird, supporting the notion that at least some of the most ancient birds performed aerodynamic feats in a fashion similar to those of many living birds.
Typhoon Choi-wan continued to move north in the western Pacific Ocean as NASA's Aqua satellite passed overhead in space on Oct. 6 and took an infrared look at the storm. Earlier, the RapidScat instrument aboard the International Space Station measured the storm's strongest winds.
This work demonstrates an improved three-dimensional energy storage device constructed by trapping functional nanoparticles within the walls of a foam-like structure made of nanocellulose. The foam is made in one step and can be used to produce more sustainable capacitor devices with higher power density and faster charging abilities compared to rechargeable batteries. This development paves the way towards the production of lightweight, flexible, and high-power electronics for application in wearable devices, portable power sources and hybrid vehicles.
Tropical Storm Oho intensified into a hurricane on October 6 and appeared to have a 'tail' in Infrared NASA satellite imagery. Oho is the seventh hurricane of the 2015 season in the North Central Pacific Ocean.
A new study on Homo naledi, the extinct human relative whose remains were discovered in a South African cave and introduced to the world last month, suggests that although its feet were the most human-like part of its body, H. naledi didn't use them to walk in the same way we do. Analysis of 107 foot bones indicates that H. naledi was well adapted for standing and walking on two feet, but that it also was likely comfortable climbing trees.
