A miniature magnetic resonance imager made of diamond      (via sciencedaily.com)     Original source 

The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team has now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging.

Cobalt-free battery for cleaner, greener power      (via sciencedaily.com)     Original source 

High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. A team now presents a viable alternative to cobalt which in some ways can outperform state-of-the-art battery chemistry. It also survives a large number of recharge cycles, and the underlying theory can be applied to other problems.

How to build greener data centers? Scientists say crank up the heat      (via sciencedaily.com)     Original source 

Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.

New recipe for efficient, environmentally friendly battery recycling      (via sciencedaily.com)     Original source 

Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid -- an organic acid that can be found in the plant kingdom.

Research finds water quality in Gulf of Mexico improves when adding social costs to carbon emissions      (via sciencedaily.com)     Original source 

Researchers took a closer look at what would happen to agriculture if there was an extra cost, or so-called social cost, added to fossil fuels, which are essential for making fertilizer used in farming. They found that while CO2 emissions would decline by as much as 50%, the cost of fertilizer would rise leading to a significant benefit on water quality by lessening fertilizer runoff contributing to the Gulf of Mexico's dead zone.

Over 40 percent of Antarctica's ice shelves reduced in volume over 25 years      (via sciencedaily.com)     Original source 

71 of the 162 ice shelves that surround Antarctica have reduced in volume over 25 years from 1997 to 2021, with a net release of 7.5 trillion tons of meltwater into the oceans, say scientists.  They found that almost all the ice shelves on the western side of Antarctica experienced ice loss. In contrast, most of the ice shelves on the eastern side stayed the same or increased in volume.  Over the 25 years, the scientists calculated almost 67 trillion tonnes of ice was exported to the ocean, which was offset by 59 trillion tons of ice being added to the ice shelves, giving a net loss of 7.5 trillion tons.

Large swings in past ocean oxygen revealed      (via sciencedaily.com)     Original source 

As the climate warms, there is major concern that Earth's ocean will lose oxygen. A study has revealed that locked in ancient deep-sea sediments is evidence for oxygen loss in the world's ocean during past glacial periods, indicating that widespread oxygen loss with current climate change may not be permanent.
