6 . On Monday, a lawsuit (诉讼) in the US got huge headlines around the world. It deals with a truly 21st century issue—whether human genes (基因) may be patented.
Myriad Genetics, a biotechnology company, discovered two genes — BRCA 1 and BRCA 2 — that are highly related to breast cancer. Myriad patented its discoveries and a group of researchers challenged that the patent was illegal.
The US patent law protects the temporary economic rewards inventors get from their inventions. But it also says a product of nature or a law of nature can’t be patented. For example, Einstein couldn’t patent on his discovery of E=mc2.
And until relatively recently, many of the medical researchers voluntarily gave up patents on their inventions. When Dr. Jonas Salk, the inventor of the polio vaccine (小儿麻痹症疫苗), was asked in 1955 whether he had a patent on the vaccine, he replied, “Could you patent the sun?”
Myriad Genetics, however, says that the genes it identified are not like the sun. It notes that there are 20,000 genes in the human body and that it has sorted through all those genes and found the two that are closely related to breast cancer.
Not so, say those challenging the patent. Human genes are products of nature. They are just a part of the human body. “All Myriad does is take the part out of the body,” says the challengers’ lawyer, Christopher Hansen. “Can the person who first takes the heart out of the body patent on hearts?”
Rochelle Dreyfuss, a patent expert who is not associated with this case, is a little more down to earth. “At some level it is about money,” he says, “because medicine doesn’t happen for free. The patent system is very important to encourage companies to spend more money on scientific research and development.”
Then how do other countries handle this tricky situation? Most countries approve patents on genes, but they also allow other scientists to use the genes freely to do research and develop new medicines and testing methods.

7 . With the widespread use of smartphones, emojis (表情符号) have become a popular medium for expressing emotions and ideas. Researchers now believe these expressive symbols can play a significant role in medicine, increasing the response rate of health surveys.
Scientists say that employing emojis in healthcare communications has several benefits, such as general recognition across diverse populations. So the study authors strongly support the use of emojis to bolster communication between patients and physicians.
“By promoting more effective communication between patients and care providers, as well as between physicians themselves, an emoji-based language system with a common agreement of meanings can be developed,” says Professor Kendrick Davis, who is an associate professor at the UCR School of Medicine. The professor has been working on creating an emoji-based measurement system for the past two years. And he has even conducted a study using emojis to measure health among college students.
Davis further explains that a significant part of medical communication includes surveys, which are often areas of communication breakdown. “Surveys are usually passed to patients in a variety of different stages of their care. But many surveys are explained with language that can introduce an obstacle. This is where emojis, which are friendly and widely used, come into play by replacing survey language that can be hard for some patients to understand,” he says. The authors also point out that while effective communication is important for successful treatment and care, certain health conditions such as brain injury can cause major obstacles. In such cases, emojis could be helpful.
However, Davis also acknowledges the importance of qualitative (定性的) methods. He expresses an interest in partnering researchers whose methodologies are heavily qualitative.

Then came the outbreak of COVID-19 in Wuhan. With the number of
10 . For years, doctors have given blood to patients who need it to survive. These transfusions usually include giving red blood cells to patients.
Blood transfusions aren’t as simple as taking blood from one person and giving it to someone else. There’re several different blood types that don’t all mix well. If someone gets a transfusion of the wrong kind of blood, their body will reject the blood cells, causing problems. For the first time ever, scientists from the University of Bristol, Britain, are carrying out a new trail: testing red blood cells grown in a laboratory on human volunteers. The scientists have used stem cells (干细胞) from a blood sample to grow billions of brand new red blood cells.
This could be even better than a regular blood transfusion. For one thing, they can be adjusted for people with different blood types. That’ll be extremely helpful for people with rare blood types. Also, a normal transfusion has red blood cells of all different ages, which means only a small part of them are brand new. The red blood cells grown in the lab are brand new, and this means they last longer and that patients will need fewer transfusions.
To test its safety, researchers have given a couple of teaspoons of the blood to two healthy people, both of whom seem to be doing just fine after the transfusions. In all, they’ll be tested on 10 people, and compared to normal transfusions. The new process doesn’t indicate that normal blood transfusions will disappear. Meanwhile, growing red blood cells in a lab is extremely expensive. And a lot of work and testing still need to be done. But if it’s successful, the process could make life much easier for patients who often need transfusions—even those with rare blood types.
