Dramatic progress has been witnessed in the Traditional Chinese Medicine (TCM) which benefits from those great contributions some ancient famous doctors made ant some experience they accumulated. The following three stand out among the ancient famous doctors.

Hua Tuo

Hua Tuo (145—208), famous physician of the late Eastern Han dynasty, also named Fu, was born at Qiao County in Peiguo (now Bozhou, Anhui Province). He led a simple life, away from fame and fortune. He would rather become a traveling physician for ordinary people.

Hua Tuo was an expert in several medical fields, such as internal medicine, surgery, gynecology, pediatrics and acupuncture. He was the first person to perform surgery with the aid of anesthesia (by applying Ma Fei San, a herbal anesthetic he invented) some 1,600 years before Europeans did.

Zhang Zhongjing

Zhang Zhongjing (150—219), also known as Zhang Ji, was one of the most distinguished Chinese physicians during the later years of the Eastern Han dynasty. He lived in today's Nanyang in Henan Province. He was known as the "medical sage" by later generations due to his outstanding contributions to TCM.

During his time, with warlords (军阀) fighting for their own territories, many people were infected with fertility, an illness caused by fever. Zhang's family was no exception. The experience stimulated his motivation in medicine. He learned medicine by studying from his town's fellow Zhan Bozu, absorbing previous medicinal literature, collecting many prescriptions; and finally writing the medical masterpiece Shanghan Zabing Lun. Unfortunately shortly after its publication the book was lost during wartime.

Li Shizhen

Li Shizhen (1518—1593) was a famous medical scientist the Ming dynasty. He loved medicine from an early age and succeeded his ancestors as a doctor. He not only paid attention to accumulating experience in curing diseases, but also visited the famous mountains where medicinal materials were produced.

On this basis, it took 27 years to compile (编著) the pharmaceutical masterpiece, Compendium of Materia Medica, which is known as the "Encyclopedia of Ancient China" and has made an important contribution to the development of classical medicine China.

According to the Solar Energy Industry Association, the number of (74)solar panels installed（安装）has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them. 

Solar developers want to put up panels as quickly and cheaply as possible, so they haven't given much thought to what they put under them. Often, they'll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil. 

"Solar projects need to be good neighbors," says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment（InSPIRE）project. "They need to be protectors of the land and contribute to the agricultural economy." InSPIRE is investigating practical approaches to "low-impact" solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators（传粉昆虫）.

Habitat loss, (75)pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms. 

Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. "These pollinator-friendly solar farms can have a valuable impact on everything that's going on in the landscape," says Macknick.

The success of many North American crops partly depends on ground beetles, small insects that eat pests and weed seeds that could otherwise damage crops. But a new study by researchers in the U. S. and Canada suggests not all of the nearly 2,000 species of ground beetles found in North America will survive climate change. Some could decline. And that could have a far-reaching impact on agriculture, forestry, and conservation.

By analyzing data on 136 different ground beetle species across continental North America, Puerto Rico and Hawaii, the researchers found that a species' chance of success in a changing climate depends on several important factors, such as its habitat preference, body size, and whether it flies, climbs or runs.

"We found that less mobile, nonflying ground beetles, which are critical pest control agents, are more likely to decline over time in a warmer, dryer climate," said Tong Qiu, who led the study. "That means you're going to have more pests that can impact agricultural and forest ecosystems." But there is reason for hope, Qiu added, because the analysis also showed that habitat conservation can lessen these effects and reverse the trends in some areas.

"We hope conservation biologists will use this information and the online map that we created to better manage habitats for insects in general. Ground beetles are very beneficial to ecosystems, but they're largely invisible to the average person. In this paper we're showing the broad impacts they have on whole communities in forested and agricultural ecosystems," said Qiu.

The researchers used ground beetle count data from the National Science Foundation's National Ecological Observatory Network (NEON) and from 11 previously published studies to measure and map the beetles' distribution across North America. Habitat information, such as the location of gap s in forest canopies and the density of plants on a forest floor, was obtained by using NEON's imaging instruments to create detailed three-dimensional images of landscapes. They then entered the data collected into a computer model to simulate (模拟) climate changes to study how the insects would respond.
