The year 2014 ranks as Earth's warmest since 1880, according to two separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA) scientists. The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000. This trend continues a long-term warming of the planet, according to an analysis of surface temperature measurements.

A NASA study using two years of observations from a novel mountaintop instrument finds that Los Angeles' annual emissions of methane, an important greenhouse gas, are 18 to 61 percent higher than widely used estimates. The study is the first to demonstrate the feasibility of long-term mapping of greenhouse gases across an urban area from an elevated -- but still earthbound -- site.

A new serotype of the salmonella bacteria has been discovered by Texan researchers. Because convention calls for a new serotype to be named after the city in which it is discovered, this one will be called Salmonella Lubbock. And while Lubbock is known for many things, like being the home of Buddy Holly, this new honor will provide new avenues for research into the bacteria's prevention, researchers suggest.

Researchers are beginning a study of the climatic effects of peat fire emissions. "This project is going to provide the much-needed information on peat smoke aerosol properties for integration in satellite retrieval algorithms and climate models," the lead researcher says. "Based on my initial findings, I hypothesize the peat smoke is made up of brown carbon and not black carbon. Brown carbon is a class of organic carbon aerosol which, unlike black carbon, strongly absorbs incoming solar radiation in the shorter wavelengths, or near ultraviolet."

The Pyrenees are home to continental Europe's only wild population of bearded vultures, a species classified as endangered in Spain. A study compiled by Spanish researchers reveals -- in a level of detail until now unseen -- the size of the home range of this bird species using satellite tracking technologies.

A new study of dolphins and seals shows that despite their remarkable adaptations to aquatic life, exercising while holding their breath remains a physiological challenge for marine mammals. The study found a surprisingly high frequency of heart arrhythmias in bottlenose dolphins and Weddell seals during the deepest dives.

A new volcanic eruption commenced on Fogo, one of the Cape Verde Islands, on November 23rd, 2014. This eruption continues to date, and is considered to be the largest eruption by volume, and in terms of damage, on the archipelago for over 60 years. Most damage was caused by lava flows advancing into populated regions, so that numerous buildings, homes and roads were destroyed. In total, three villages have been abandoned and thousands of residents have had to be evacuated.

One way of removing harmful nitrate from drinking water is to catalyse its conversion to nitrogen. This process suffers from the drawback that it often produces ammonia. By using palladium nanoparticles as a catalyst, and by carefully controlling their size, this drawback can be partially eliminated, researchers have discovered.

Amid the black-market pet trade in Manila, researchers have discovered two species of water monitor lizard that previously were unknown to science. Manila's criminal trade in animals ranges from pet stores "with many endangered and illegal species hidden behind the scenes" to major international wildlife violators and wholesale smuggling rackets.

The molecule known as coenzyme A plays a key role in cell metabolism by regulating the actions of nitric oxide. Coenzyme A sets into motion a process known as protein nitrosylation, which unleashes nitric oxide to alter the shape and function of proteins within cells to modify cell behavior. The purpose of manipulating the behavior of cells is to tailor their actions to accommodate the ever-changing needs of the body's metabolism.

Root and foliar spray abscisic acid applications were studied to determine how ABA affects the incidence of blossom-end rot in distal tissue of tomato fruit. A combination of spray and root ABA applications resulted in the greatest decrease in blossom-end rot. ABA treatments were deemed effective in increasing fruit calcium and preventing BER in early stages of plant development, but were found less effective in preventing calcium deficiency in later stages of growth.
