Everyexpecting mother gets to ask (asked) thequestion, boy or girl? For mammals like us, it is an easy call. Two Xchromosome(s) you get paint buddies (pink booties). X and Y, you get blue. But for somereptiles, the answer depends on the weather. Well, on the temperature to be precise,for many lizards, turtles and gators, the sex of the hatchling(s) depends on the temperature in the nest where the eggsincubate. But why we(would) animals bother withsuch a seemingly slapdash system for a signing（assigning）sex? But (And the)only logical answers (answer is), there must besome benefit. Each sex must fear (fare) betterat the temperature that tends to produce that sex. A fine theory, but no onewas (has been) able to test it until now. In theJanuary 20 online issue of nature, scientists of (at)Ohio (lowa) State University describe how theyused hormone(s) to produce lizard(s) with the wrong sex. Animals that came out maleeven though they were incubated that (at) the femaletemperature, and vice versa. They found that females born and raised at the femaletemperature, made more babies, that (than)female(s) hatched (+at)the wrong male temperature. Did all(Ditto) for the males. Call it the golden locked(Goldilocks) principle. You bore(are born) at the(a) temperaturethat is just right, at least of your(if you area) lizard.

The search for alternative fuel to gasoline is less (led to) dispraising (surprising)possibilities, for instance, the wasting (waste)oil for making French fries. But one of the most unusual alternativefuel candidates might be chicken fat. Yes, chicken fat is(去掉) also calledshmoz(schmaltz). So if you make chicken soup,you might have a valuable resource in your kitchen besides the actual soup.Chemical engineers at the University of Arkens(Arkansas)report, that when chicken fat is combined with mesolon(methanol)under very high temperatures and pressure, known as supercriticalconditions, they got biodiso. The method converted 89 percent of the chickenfat to biodiso（bio-diesel）. The research was done as part of a master’s thesis project by chemicalengineering student Bredge Sooty(Brent Schulte).Many people have high hopes for biodiso（bio-diesel） as a replacement for fossilfuels, because it uses renewable resources such as plant oils or in this casechicken fat, which they are(there’s)certainly known(no) shortage. The hunt forbiodiso（bio-diesel）may mostly take place outdoors, but the potential of the French fry //(flotsam) and chicken fat also means the search cansometimes end in the kitchen.

Air pollution is bad for ourhealth. But scientists say we don’t know much about the long term effects. Soresearchers in Canada and another land (the Netherlands)decided to gather genetic information in (+an) urbanand(去掉) industrial environment by lookingat mice burn(mouse sperm). They publish(ed) thestudy in the proceedings of national economy (Academyof) sciences. The scientists place(d)cages of mature male mice near two still males(steel mills) in(and) a major highway in the city of Himotorn in Motanral(Hamilton, in Ontario) Canada. Some of themice breathed in the particular feed （in ambient, particulate-filled ）air.The control mice breathed peer /（pure, filtered） air. Afterten weeks, researchers checked the two groups. The mice exposed to the pollutedair had a 60 percent higher rate of sperm mutation. It occurred in a piece ofDNA particular(ly) susceptible to mutation.Researchers say these specific mutations are known to affect gene expression andgeno stability and could lead to changes in genetic compensation and disease.They say they can’t yet extraply（extrapolate）from thesefindings to (the) long term /(health) effects to（in） humans. But they say the results definitelywarn(warrant) a more detailed look at pollution’s effects on our genes.

//(Vinaigrette) dressing: when you shake it,little //(vinegar) droplets scatter through the oil. But when you put it down,thedroplets merge and the dressing separates. That’s probably not a big inconvenienceto you, but it is in (to) industries that use lotsof vinegar like (vinaigrette-like)mixtures. So the (to) study designs(this) mixing (unmixing),French researchers planned to float water droplets when it is the(one at a) time to channel a flown(of flowing) oil. The channel is wide (widened) in the middle so the oil would slow downin //(and bump) the droplets together. Thenthe passage narrow(ed) again and so the oil wasspeeded(would speed) up and pour(pull) the droplets apart. The researchers expectedthat the droplets would merge when they bumped together. But that is not whathappened. In fact, it was when the droplets start(ed) topour(pull) apart from each other that theysuddenly mixed. In physical review letters, the researchers say that thepouring (pulling) apart may make the pressure betweenthe droplets fall. That would make the droplets burst open and then they couldmerge into one big water droplet. What the researchers don’t say is whetherthis finding could lead to a true breakthrough: stay-mixed salad dressing.

When this(is an) ant is(去掉) like a piece of fruit? When itaffected (is infected) by a parasite? Researchersaffiliated with a monsoonal（the Smithsonian）tropical research institute discovered this bizarre occurrence in centralAmerica as they were studying the gliding ability of（+a） certain species of ant. They found somecolony members with bright red through abdiments(swollen abdomens). Thescientists took specimens back to the lab and discovered they were full ofhundreds of manifold（nematode）eggs. The bright red ballet (bellies) look suspiciouslylike (+the) brilliant red and pink berries that //(proliferate) in the rainforest. Researchersthink that the nimitold（nematode）makes the ant looks like fruit to get birds（+to） eat the ants. Birds usually keep the antsof (off) their menu because of armer(armor) and（+a） bad chemical taste. The birds then spread parasiteeggs in their droppings, // (Ants forage through bird) droppingsfor seeds. They feed the affected (infected)droppings at lava (to ant larvae) beginningthe infection process all over again. The red ballet(red-bellied)ant is the first known case of parasite causing fruit mimicry. One of theresearchers were surprised to that something, dam(dumb)as //(a nematode), can perpulate(manipulate) its host in such a sophisticated way, butevolution works no matter how dam(damb) organisms are.

When you have an itch, nothing feels betterthan a good scratch. Now scientists from W University (Wake Forest UniversityBaptist) medical center think they know why. The scientists werewondering why weaking figures node(raking fingernails) across skin brings(+us) such a(去掉) pleasure. So they look(ed) to thebrain, more precisely they looked into(in) thebrain. Using advanced emyging(imaging) techniques,the scientists look(ed) to see which parts ofthe brain are most active when people scratch or in this case, when people(+are) scratch (ed) bya guy(+in) a white lamb(lab)coat with a special scratching brash(brush). Whatthey find (found) is scratching is(does) not the activist areas of the brain normallyassociated with the pleasure. Although it did boost the activity of the preferto context(prefrontal cortex)whichcan be involved in comprehensive(compulsive) behavior.That makes sense. But the major effect of scratching was to decrease theactivity of brain region(s) associated with unpleasantsensory experiences. So scratching seems to relieve the unpleasant feeling(s) that accompany, well, itching. Yes, (+in) a landmark study that appears in the Journal of investigativedermatology scratching gets rid of the itch. Me, I am holding there (out) for the study that chose (shows) that people bent (bang) theirheads against the wall because it feels so good when you stop.

Hitting your mid forties,(?) chances are you(+are)feeling down. But don’t hang you head, you are just at the bottom of the life(‘s) U shape(d) hap (path) of happiness. You might not see it if from herebut things are looking up. A study in the Journal of(去掉) Social Science Medicine saysmid-life melan（malaise）is part of being human. Ofrey(Offering) proved(proof) that misery loves company researchers foundthat millions of people from 74 different countries followed similar life path.They moved from youthful happiness towards mid-life depressions then back tohappiness in their golden years. Earlier studies suggested psychological well-beingwas consistent devout(throughout) life. But thisreport says from //( Azerbaijan) to Sibabowi(Zimbabwe,), there is no getting around that mid-lifecrisis, regardless of culture differences, financial success or merical(marital)status, a peer(period) of depression settlesover our forties. And(But) by our late fifties,we cheer back up. Researchers speculate that as we get older, unrealisticexpectations are tempered by reality. In other words, we learn to expect lessfrom life. But they say a happier possibilities (+is)that we just get better and (at) counting our blessings.
