Engineers build a battery-free, wireless underwater camera

Researchers built a battery-free, wireless underwater camera, powered by sound waves, that can take high-quality, color images, even in dark environments. It transmits image data through the open water to a receiver that reconstructs the color image.Researchers built a battery-free, wireless underwater camera, powered by sound waves, that can take high-quality, color images, even in …

What keeps plant roots growing toward gravity? Study identifies four genes

What happens belowground in a corn field is easy to overlook, but corn root architecture can play an important role in water and nutrient acquisition, affecting drought tolerance, water use efficiency, and sustainability. If breeders could encourage corn roots to grow down at a steeper angle, the crop could potentially access important resources deeper in …

Study finds all African carnivores at risk for range loss

A new study assessing 91 African carnivores to identify gaps in capacity necessary for their conservation found that many species that are currently classified as ‘least concern’ on the International Union for the Conservation of Nature Red List of Threatened Species had high percentages of their range at risk of contraction.A new study assessing 91 …

Casting shadows on solar cells connected in series

Even small objects, such as dust and leaves, can block sunlight from reaching solar cells, and understanding how the loss of incoming radiation affects power output is essential for optimizing photovoltaic technology. Researchers explore how different shade conditions impact performance of single solar cells and two-cell systems connected in series and parallel. They found that …

Catalytic process with lignin could enable 100% sustainable aviation fuel

An underutilized natural resource could be just what the airline industry needs to curb carbon emissions. Researchers report success in using lignin as a path toward a drop-in 100% sustainable aviation fuel. Lignin makes up the rigid parts of the cell walls of plants. Other parts of plants are used for biofuels, but lignin has …

New research can help electric utilities account for climate change

Researchers have devised a method to determine the impact of climate change on the supply and variability of local renewable energy. An increase in unusual weather patterns related to climate change means the demand for power and the availability of solar, hydro and wind energy can all become more variable.Researchers have devised a method to …

Revealing the genome of the common ancestor of all mammals

An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals and in conservation of modern animals. The earliest mammal ancestor likely looked like the fossil animal ‘Morganucodon’ which lived about 200 million years ago.An international team has …
