Correcting historic sea surface temperature measurements  

Why did the oceans warm and cool at such different rates in the early 20th century? New research points to an answer both as mundane as a decimal point truncation and as complicated as global politics. Part history, part climate science, this research corrects decades of data and suggests that ocean warming occurred in a much more homogenous way.

What counts for our climate: Carbon budgets untangled  

The more CO2 we emit from burning coal and oil and gas, the more we heat our climate -- this sounds simple, and it is. Different analyzes have come up with different estimates of how much CO2 humankind can still emit if we want to hold global warming to the internationally agreed 1.5 and well below 2 degrees Celsius limits, but a lack of clarity of the reasons causing these variations has created unnecessary confusion, a new study shows.

DNA origami joins forces with molecular motors to build nanoscale machines  

For decades, researchers have chased ways to study biological machines. Every mechanical movement -- from contracting a muscle to replicating DNA -- relies on molecular motors that take near-undetectable steps. Trying to see them move is like trying to watch a soccer game taking place on the moon. Now, with DNA origami helicopters, researchers have captured the first recorded rotational steps of a molecular motor as it moved from one DNA base pair to another.

Red algae steal genes from bacteria to cope with environmental stresses  

It's a case of grand larceny that could lead to new fuels and cleanup chemicals. Ten species of red algae stole about 1 percent of their genes from bacteria to cope with toxic metals and salt stress in hot springs, according to a new study. These red algal species, known as Cyanidiales, also stole many genes that allow them to absorb and process different sources of carbon in the environment to provide additional sources of energy and supplement their photosynthetic lifestyle.

Batteries power our lives: we rely on them to keep our cell phones and laptops buzzing and our hybrid and electric cars on the road. But ever-increasing adoption of the most commonly used lithium-ion batteries may actually lead to increased cost and potential shortages of lithium -- which is why sodium-ion batteries are being researched intensely as a possible replacement. They perform well, and sodium, an alkali metal closely related to lithium, is cheap and abundant.

Scientists have discovered that a specific brain cell known as a 'projection neuron' has a central role to play in the brain changes seen in multiple sclerosis (MS). The research shows that projection neurons are damaged by the body's own immune cells, and that this damage could underpin the brain shrinkage and cognitive changes associated with MS. These new findings provide a platform for specific new MS therapies that target damaged brain cells to be developed.

Sea level rise requires extra management to maintain salt marshes  

Salt marshes are important habitats for fish and birds and protect coasts under sea level rise against stronger wave attacks. However, marshes themselves are much more vulnerable than previously thought. Stronger waves due to sea level rise can not only reduce the marsh extent by erosion of the marsh edge, but these waves hamper plant re-establishment on neighboring tidal flats, making it much more difficult for the marsh to recover and grow again.

Resistance is utile: Magnetite nanowires with sharp insulating transition  

Scientists have produced Fe3O4 nanowires on 10-nm length scales by deposition on an MgO substrate.
