1 . Neudy Rojop, 29, looks across the rough, rocky road in the small rural village of San Rafael Pacaya. It leads to the home where she grew up and where she still lives today.
When Rojop was about 10, her cousin, Carlos, was very sick. Without any local clinics (诊所), Rojop’s family couldn’t even figure out what the disease was. They could do nothing but wait. Growing up, she noticed how frequently many of those around her were getting sick. As a teenager, she started to realize her community needed better chance to health care. So she determined to go to a nursing school.
But her vision was beyond being a nurse. After graduation, she realized one person was not enough to make the community better. “The people here may have common diseases,” she thought. “Some are known. But there may be new diseases that we don’t know about.” She wanted to do something to keep any illness from being a threat in the first place. She wanted to train people and do some research to monitor these illnesses and try to provide early actions, or try out new ways to prevent some of them.
Over the next few years, she and a small team brought her vision to life. They provided measures that could limit the possible risks. Olson, one of her colleagues, recalled, “She has zero clinical experience and zero research experience at first, but now she is a superstar here. Her working place is usually busy with about 300 patients per month.”
Now Rojop starts her days with a morning meeting, making decisions, solving problems and setting priorities with her teammates. “In the past, I was so young that I could do nothing for my community,” she says. “But now I can help because I know how.”

3 . We’ve all been told that different types of fruits and vegetables have different benefits that help us keep healthy. A new international study has found that eating one fruit regularly can help reduce the risk of cancer (癌症), among those people who have a high risk of developing certain cancers.
The research, which followed almost 1,000 patients with a variety of cancers, found that taking regular resistant starch (抗酶解淀粉) could have a great preventative effect on the risk of cancer. Here’s what you need to know about how eating bananas regularly can help reduce the risk of cancers.
Resistant starch is found in green bananas. By eating green bananas your body gets resistant starch, which has been found to reduce the risk of cancers in some parts of the body by more than a half, according to the new research. The study, which was published in Cancer Prevention Research, was led by experts at the Universities of Newcastle and Leeds. It found that resistant starch, if taken regularly for two years, had a very good effect on some cancers, which can be difficult to find.
John Mathers, a professor at Newcastle University explained, “Resistant starch really helps in fact, which has several health benefits and fewer calories than regular starch.”
In addition to green bananas, resistant starch is also found in foods such as peas, beans and other starchy foods. In terms of bananas, experts think that eating one banana every day has the same effect as a certain amount of resistant starch. The secret is to eat the bananas before they become too ripe (成熟的) or soft.

4 . Nearly 40 percent of Americans over the age of 65 take five or more different drugs, and doctors often simply have to monitor patients to see if any of those drugs combine to createnegative side effects. When a doctor prescribes(给……开药)a patient more than one drug atthe same time, they currently have no way to predict whether that combination of these drugswill have a negative side effect. A new system from a team of computer scientists at Stanford University presents a novel solution—an AI-driven computer system that can predict theconsequences of combining two drugs.
Drug combinations are a remarkably unstudied area, but as Marinka Zitnik explains, “It’spractically impossible to test a new drug in combination with all other drugs, because just forone drug that would be five thousand new experiments.” Besides, to maintain accuracy alsoneeds strict research procedures.
So Zitnik and her Stanford colleagues set out to find a solution to the problem. They created a massive deep learning system trained on data encompassing(包含)over l9,00 oproteins and how different drugs interact with those proteins. The system is called Decagon, and it can effectively predict the consequences of combining any two different drugs.
To test out Decagon’s predictive abilities the team examined 10 of the systems predicted drug pair interactions that didn’t have clearly known unfavourable interactions. The researchers found new supporting case study evidence backing up 8 of those 10 predictions. For example, one prediction from Decagon suggested muscle inflammation(炎症) would be caused by combining a certain cholesterol(胆固醇) drug with a blood pressure medication. This negative side effect of combining those two drugs was only recently confirmed by a casestudy published in 2017.
The next stage in the project is to try to turn Decagon into a more user-friendly tool thatdoctors can easily navigate(导航) for information when prescribing combinations of drugs, benefiting more people. At this stage, the system only evaluates(评估) drug pairs but there searchers hope to expand that into more complex combinations of drugs in the future.

7 . Reasons why you should learn first aid
A first-aid course only takes a matter of hours to complete but supplies you with all of the knowledge you require to handle an emergency.
Having the ability to help family and friends in need. When a member of your family or a friend injures himself or herself, there’s nothing worse than feeling helpless. In your first-aid training, you can learn how to treat a variety of medical conditions and injuries. This means that when someone is in need, you will know exactly what to do.
Earning the respect of your fellow colleagues.
Gaining new responsibilities. Your role as a first-aider is very important especially in high-risk working environments where employees are operating heavy machines or working at a great height.
A.But that’s not all |
B.Getting more confidence |
C.You will be the go-to person in times of need |
D.Having the pride you will feel if you help save someone |
E.We all know that accidents happen, but we cannot predict the future |
F.Your knowledge of first aid will increase their chance of making a quick recovery |
G.Stepping in to help your colleagues will have a greater effect than you might expect |
8 . Some women with severe anorexia (厌食症) have returned to a healthy weight and feel less anxious after having electrical devices implanted into their brains, which is based on a small study. But more research is needed.
About one in five people with anorexia die of the illness and there is a lack of effective treatments. Imaging studies suggest that certain brain circuits (回路) may underlie the fear of gaining weight and compulsion (强迫) to self-starve.
Bomin Sun at Shanghai Jiao Tong University School of Medicine in China and his colleagues wondered whether they could harm these circuits by electrically affecting a part of the brain known as the nucleus accumbens (伏隔核). This brain region helps us to learn from experience, but in people with anorexia it seems to form abnormal connections with other brain regions.
The team took in 28 women with at least a three-year history of anorexia who hadn’t improved following standard treatment. The women had an average body mass index (BMD) of 13; a BMI of less than 18.5 is considered underweight. A BMI between 18.5 and 24.9 is considered normal. A BMI between 25 and 29.9 is considered overweight. The researchers surgically implanted electrodes (电极) into the nucleus accumbens on women’s brains. They connected the electrodes by wires to a battery, to continuously affect the nucleus accumbens.
Over the next two years, the average BMI of the participants increased to 18 and almost half regained a BMI of 18.5 or above. They also reported feeling less anxious.
“This is a very promising result,” says Philip Mosley, a research from Australia. But the study didn’t include a placebo (安慰剂) group for comparison, meaning it isn’t possible to rule out that the participants’ improvement was simply because they expected the treatment to work, says Mosley.
Mosley and his colleagues are about to start a trial of the same treatment in which they will control for the placebo effect. Brain surgery may seem like an extreme treatment, but for people with severe anorexia, it may be better than the alternative, which is often death, says Mosley.
