In the fall, a layer of cells in the stem weakens and the plant breaks off from its roots and rolls ( across the fields in the wind.

Long-s doctrin holds that we are protected from fungi not just by layered immune defenses but ( e ) we are mammals*, with core temperatures higher than fungi prefer. The cooler outer surfaces of our bodies are at risk of minor assaults-think of athlete's foot*, yeast infections, ringworm*-but in people with healthy immune systems, invasive* infections have been ( f ). That may have left us overconfident. "We have an enormous (g) spot," says Arturo Casadevall, a physician and molecular microbiologist at the Johns Hopkins Bloomberg School of Public Health. "Walk into the street and ask people what are they afraid of, and they'll tell you they're afraid of bacteria, they're afraid of viruses, but they don't fear dying of fungi." Ironically, it is our successes that made us vulnerable*. Fungi exploit damaged immune systems, but before the mid-20th century people with impaired immunity didn't live very long. Since then, medicine has gotten very good at keeping such people (h), even though their immune systems are compromised by illness or cancer treatment or age. It has also developed an array of therapies that deliberately suppress immunity, to keep transplant recipients healthy and treat autoimmune* disorders such as lupus* and rheumatoid arthritis*. ( i ) vast numbers of people are living now who are especially vulnerable to fungi. Not all of our vulnerability is the fault of medicine preserving life so successfully. Other ( j ) actions have opened more doors between the fungal world and our own. We clear land for crops and settlement and perturb* what were stable balances between fungi and their hosts. We carry goods and animals across the world, and fungi hitchhike on them. We drench crops in fungicides* and enhance the resistance of organisms residing nearby. (s) ELSE

closer to reality. Researchers have investigated the use of electricity to stimulate vision for nearly half a century. In the 1960's, a *physiologist implanted 80 electrodes on the surface of a blind person's *visual cortex, a region at the back of the brain. Wireless stimulation of the electrodes made the patient see spots of light known as *phosphenes. This is the first stop for visual signals coming from the eye. (D) By the 1980's, a crop of *ophthalmologists began considering a narrower and seemingly easier-to-solve problem: making *prostheses for the eye. They suggested that degrade *photoreceptor cells called *rods and cones, still leave large portions of the retina intact even after a patient has become totally blind. The way to stimulate the remaining functional cells was proved *feasible in the mid-1990's. A device consisting of a tiny video camera perched on the bridge of a pair of glasses, a belt-worn video processing unit, and an electronic box, was developed recently. The electronic box issues signals to an implant behind the patient's ear that has wires running to a grid of 16 electrodes affixed to the output layer of the retina. The video processor wirelessly transmits a simplified picture of what the camera images to the box, and then the retinal implant stimulates cells in a pattern roughly reflecting that information.

テーマ 専門性☆☆☆ 英文レベル★★★ 30 DNAはウイルスから? 文 11 What with the threat of bird flu, the reality of HIV, and the genera unseemliness of having one's cells pressed into labour on behalf of something alien and microscopic, it is small wonder that people don't much like viruses. But we may actually have something to thank the little 5 parasites for. They may have been the first creatures to find a use for DNA, a discovery that set life on the road to its current rich complexity 12 The origin of the double helix is a more complicated issue than it might at first seem. DNA's ubiquity -all cells use it to store their genomes - suggests it has been around since the earliest days of life 10 but when exactly did the double spiral of bases first appear? Some think it was after cells and proteins had been around for a while. Others say DNA showed up before cell membranes had even been invented/ The fact that different sorts of cell make and copy the molecule in very different ways has led others to suggest that the charms of the double 15 helix might have been discovered more than once. And all these ideas have drawbacks. "To my knowledge, up to now there has been no ⚫ convincing story of how DNA originated," says evolutionary biologist Patrick Forterre of the University of Paris-Sud, Orsay. 13 Forterre claims to have a solution. Viruses, he thinks, invented » DNA as a way the defences of the cells they infected. Little more than packets of genetic material, viruses are notoriously adept at* avoiding detection, as influenza's annual self-reinvention attests. Forterre argues that viruses were up to similar tricks when life was young, and that DNA was one of their innovations. To some researchers 25 the idea is an appealing way to fill in a chunk of the DNA puzzle. 270 •
