Lost tombs and quarries rediscovered on British military base in Cyprus      (via sciencedaily.com)     Original source 

Archaeologists rediscovers 46 sites at the Eastern Sovereign Base Area at Dhekelia, Cyprus. Archaeologists located sites from archive records, a number of which were thought to have been 'lost.' They uncovered evidence of quarries and tombs likely to span from the Bronze Age, Byzantine, Hellenistic and Roman periods.

Slimming down a colossal fossil whale      (via sciencedaily.com)     Original source 

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

Experiment captures why pottery forms are culturally distinct      (via sciencedaily.com)     Original source 

Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.

Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices      (via sciencedaily.com)     Original source 

While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.

Some Pre-Roman humans were buried with dogs, horses and other animals      (via sciencedaily.com)     Original source 

Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between these humans and animals, or religious sacrificial practices, according to a new study.

Scandinavia's first farmers slaughtered the hunter-gatherer population, study finds      (via sciencedaily.com)     Original source 

Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.

Inexpensive, carbon-neutral biofuels are finally possible      (via sciencedaily.com)     Original source 

When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.

Japan's electric vehicle transition by 2035 may be insufficient to combat the climate crisis, but there are solutions      (via sciencedaily.com)     Original source 

Researchers report that Japan's policy of banning the sale of new gas vehicles by 2035 may be insufficient to reduce the country's CO2 emissions. The team's analysis showed that to effectively reach their climate goals, Japan must also implement policies that extend vehicle lifetime, implement more renewable energy into its energy sector, and decarbonize the manufacturing process of vehicles.

Improving fuel cell durability with fatigue-resistant membranes      (via sciencedaily.com)     Original source 

In hydrogen fuel cells, electrolyte membranes frequently undergo deformation and develop cracks during operation. A research team has recently introduced a fatigue-resistant polymer electrolyte membrane for hydrogen fuel cells, employing an interpenetrating network of Nafion (a plastic electrolyte) and perfluoropolyether (a rubbery polymer). This innovation will not only improve fuel cell vehicles but also promises advancements in diverse technologies beyond transportation, spanning applications from drones to desalination filters and backup power sources.

Ammonia attracts the shipping industry, but researchers warn of its risks      (via sciencedaily.com)     Original source 

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.
