There is good news- for those who enjoy     1     (run) - around in rain and don't want to get their clothes dirtied or those who play soccer but don't want their shirts to get soiled or wet with sweat. British scientists have created a fabric (织物)that never gets dirty or wet! The cloth     2     (treat) with a special non-sticky chemical that resists oil and water. This ensures that the clothes made     3     it remain clean. But the scientists are not yet ready to make public the     4     (detail) information of this "miracle" chemical.

A well-known French company recently launched     5     new range of jackets that have Teflon in them. Teflon is the plastic coating on non-stick cooking pans,    6     has a special characteristic: No reaction to anything. As a result, dirt and water slip away from the Teflon fabric, as     7    (easy) as oil slips out of a Teflon-coated pan.

American scientists have gone a step     8    (far). They have added insecticide (杀虫剂) to the fabric that kills mosquitoes on contact. This new anti-mosquito fabric     9     (find) immediate buyers shortly after its invention. According to reports, several mosquito net producers are planning     10    . (compete) with each other in the bid (投标)to "net" the company for the use of this new technology.

【推荐2】A South Korean biomedical start-up called Ybrain has developed a headband that they claim will offer relief from the symptoms of    1    (depress). The device, called Mindd, works    2    (use) a technique called transcranial direct-current stimulation (tDCS). Here, a low-voltage electrical current    3    (apply) to specific areas in the brain via electrodes (电极) placed on the skull.

tDCS is not new-the basic    4    (principle) have been understood since the early 19th century. But the past decade or so has seen increased interest in its use in treating neurological and psychiatric conditions, and a 2016 meta-analysis of hundreds of studies concluded that it’s “possibly or probably effective”    5    a treatment for depression.

tDCS equipment can stimulate particular brain regions either ‘anodally’ (increasing neuronal activity)    6    ‘cathodally’ (decreasing neuronal activity). The Mindd headset applies anodal stimulation via electrodes in the headband to the frontal lobe, an area    7    decreased activity is associated with depressive disorders. Mindd is not intended as a DIY solution: patients would use it in    8    own homes, and all data regarding treatment would be sent automatically to their doctor.

The headband is    9    (current) undergoing clinical trials at Harvard Medical School, and at 12 hospitals in South Korea. Early results are said to be    10    (promise), and if all goes well, Ybrain hopes to market the device to health providers by 2019.
