DNA analyses show the plague may have caused the downfall of Stone Age farmers
Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research.....»»
Australian amber has revealed "living fossils" traced back to Gondwana 42 million years ago
Amber is fossilized tree resin. Unlike traditional fossils found on land or in the sea, amber can preserve ancient life forms in incredible detail. It's often considered the "holy grail" of paleontology worldwide......»»

Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
From fields to policy: Conserving China"s agricultural heritage systems
Agricultural heritage systems, the custodians of ancient farming practices, face unprecedented challenges from climate change and urbanization. A recent study presents a detailed geographical analysis coupled with strategic management approaches to c.....»»
Researchers realize time reversal through input-output indefiniteness
A research team has constructed a coherent superposition of quantum evolution with two opposite directions in a photonic system and confirmed its advantage in characterizing input-output indefiniteness. The study was published in Physical Review Lett.....»»
New strategies proposed for protecting thermal barrier coatings against environmental sediment corrosion
Lei Guo and others from Tianjin University in China discovered that the environmental sediments on the surface of aero engine turbine blades have a significant concentration of Fe, surpassing even the levels of Mg, Al, and Ca in certain zones. Conseq.....»»
Brain size riddle solved as humans exceed evolutionary trend
The largest animals do not have proportionally bigger brains—with humans bucking this trend—a study published in Nature Ecology & Evolution has revealed......»»

Evidence shows ancient Saudi Arabia had complex and thriving communities, not struggling people in a barren land
To date, little has been known about people living in north-western Saudi Arabia during the Neolithic—the period traditionally defined by the shift to humans controlling food production and settling into communities with agriculture and domesticate.....»»
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as w.....»»
