Char from ancient fires and stalagmites in caves hold clues to the mysterious disappearance of Neanderthals from Europe. For more than 350 000 years, Neanderthals inhabited Europe and Asia until, in a sudden change by evolutionary standards, they disappeared around 40 000 years ago. This was at around the same time the anatomically

Barry Sharpless for their development of click chemistry and bioorthogonal chemistry. These techniques
Robert M. Dover, University of Hull On the 70th birthday of Russian president Vladimir Putin, the Nobel prize committee has recognised the work of three winners who are all battling against Putin or pro-Putin regimes. The peace prize has gone to imprisoned Belarus activist Ales Bialiatski, Russian human rights organisation Memorial and the
Wildfires are increasingly understood as an ecological driver within the entire Arctic biome. Arctic soils naturally store large quantities of C, as peat has formed throughout the Holocene. For the Siberian Arctic, we used observations from the MODIS remote sensing instrument to document changes in frequency, geographic extent, and seasonal timing of wildfires
Autonomous vehicles (AVs) are becoming increasingly popular, and this can potentially affect road performance. Road performance also influences driving comfort and safety for AVs. In this study, the influence of changes in traffic volume and wheel track distribution caused by AVs on the rutting distress of asphalt pavement was investigated through finite element
Camel meat is an ethnic food consumed across the arid regions. For these medicinal and nutritional benefits, it can be a great option for sustainable meat worldwide supply. Consumers can be benefit from the subtle taste of camel meat, flavored with aromatic and medicinal herbs from the arid regions. Research on the camel
Social affiliation is one of the building blocks that shapes cultures and communities. This motivation contributes to the development of social bonding among individuals within a group, enjoying rights, assuming obligations, and strengthening its identity. Evidence has shown that social affiliation has inspired different social phenomena, such as wars, political movements, social struggles,
After decades of merely assisting doctors, are sophisticated machines ready to take charge? By James Gaines 9.13.2022 In 2004, the United States’ Defense Advanced Research Projects Agency (DARPA) dangled a $1 million prize for any group that could design an autonomous car that could drive itself through 142 miles of rough terrain from
This paper presents an experimental platform for regulating the DC motor angular speed powered by photovoltaic cells. The experimental platform comprises an Eco Green Energy EGE-260P-60 solar panel, DC/DC SEPIC converter, DC bus, DC/DC buck converter, DC motor and Nexys 4 board with an Artix-7 100T FPGA. The DC/DC SEPIC converter is used
