ancient trees,"Berry says."Standing on the quarry surface we can reconstruct the living forest around us in our imagination. Berry and his colleagues first discovered the site in 2009 and are still analyzing the fossils it contains.Some of the fossilized roots there are 15 centimeters in diameter and form 11-meter- wide horizontal patterns spreading out from where the tree trunks once stood.Trees like those at Cairo had a big effect on the ancient climate.Deep roots stick into and break up the rocks within and below the soil.Geologists call this processing "weath- ering(风化作用)”，and it sets off chemical reactions that pull CO2 from the atmosphere e and turn it into carbonate ions in groundwater.This finally runs off into the sea and is locked away as limestone(石灰岩).

Japan is particularly easily affected by natural disasters be- cause of its climate and topography(地形)，and it has experi- enced many earthquakes,typhoons,and other types of disasters. A number of factors contribute to the high incidence of natu- ral disasters in Japan.First,the country faces extreme climatic changes,such as seasonal storms and typhoons,as well as heavy snowfall on the Sea of Japan.Second,Japan's topography is rug ged(崎岖不的).Third,Japan is located in the Pacific earth quake belt and is frequently struck by earthquakes.And fourth, Japan is located in the circum-Pacific zone,in which almost all the volcanoes of the world are concentrated,and has 83 active volcanoes-one-tenth of the world total.

stamps(食品福利券)，to pay for those groceries. Lead researcher Eric J.Brandt,national clinician scholar at Yale University's School of Medicine,hopes it is one step in find- ing more solutions for people living in areas with high rates of food insecurity.While urban food deserts were overwhelmingly covered by delivery services offered through companies,the re- sults in rural areas were not nearly as promising.The difference between partial and full delivery,Brandt explains,lies in the two sets of data:food deserts are measured by census tracts(人口普 )delivery is determined by ZIP code."They're mutually ex- clusive(各自独立的)，and they don't define each other,”hc says. There is also the challenge of paying for the delivery itself

Boss Andrew Hopkins says the news that the drug has now gone through to clinical trial shows that AI can be used not just to help diagnose disease but actually it can be used to solve one of the hardest challenges in drug research which is the creation and design of a new medicine."One of our key motivations is to ac- celerate the range of innovative drugs from cutting edge science that can then enter the clinic,and this then increases the range of treatment options available to patients,he said. Mr Hopkins adds that it was not yet clear whether drugs de- signed with AI were any better than those developed traditional- ly,but that drugs were essentially "precision-engineered prod ucts”,and algorithms(演算)could help make predictions to make design decisions more efficient.
