EXPEDITION FINDS WORLD WAR 2 NAVY WRECK

The National Oceanic (and) Atmospheric Administrations spends most of its time to try(trying) to understand and predict changes in the environment, along with conserving a managy(and managing) coastal (and) marine resources. But its scientific expertises also just make(made) it possible to look(locate) the remains that the(of the) US may be trolled boats(Navy Patrol boat) some(sunk) by a Germany sumary near the(submarine in) WW2ed.

The ship is the YP389 which went down about 20 miles of(f) the coast of Cape Hatteras, North Carolina, on June 19th, 1942. Six sailors were killed in the attack. The wreck is found (in) 300 feet water, in the(a) area called Gravy art(Graveyard) of the Atlantic. That region is the final resting place for more than 80 American, British and German vessels lost in the battle of the Atlantic.

The discovery was made during (the) summer archaeological expedition to research an(and) document to destroy(historically) significant WW2ed ship breaks(shipwrecks). The remains were(will be) surveyed by(\) photograph(ed) and document(ed) none vasively(non-invasively,) as (the) lost boats and ships (r) considered war graves.

PREHISTORIC HUMAN FASHION FIBRES FOUND

We humans love to decorate things. We wear flashing(flashy) clothes, tie ribbons to suitcases and personal as(personalize) the cases for our iphones. And apparently we have these tendencies(had this tendency) for a long long time. More than 34000 years to be exact.

Harved researchers, together with Israeli and Georgin(Georgian) Scientists recently discovered the oldest known fibres used by humans in the(a) cave by the photails(foothills) of George(ia) Caucasus Mountains. The researchers were(n't) searching for thread. They were looking for tree pollen samples that will(would) reveal how the(\) environmental and temperature fluctuations influence on(influenced) people's lives. But they knew that(they'd found) sth. has started(historic) when they saw color(the colored) thread.

The fibres were made from wild flax. Some were twisted indicated(indicating) rope, while others were not(knotted). They might be(have been) used to sew pieces of clothing to keep these ancient people warm. Or maybe tighted(tied) together packs that what allowed a(would allow) group to be more mobile. These strings could also observed as dishandled first term(have served as handles for stone) tools. The fibres were colored blank, grey, t(turquoise) and pink. So in addition, (to) cave pintings(paintings) we now have evidence of cave fashion, the first tentative steps on the way to cave of evoke(the cover of Vogue).

TREE ELECTRICITY TUNS NANO-GADGET

If scientists have their way, we may something may tapping mapples, not for pancake fences, but for power. Because researchers in the Univ. of Washington in Seattle have found another electricity in trees to run electronic in circuit. If u made a potato battery, u know the planned material can generate current. But the energy in trees is sth. else entirely. The potato eperiment use electric tool of 2 different medals to set up a charge difference get electrods on flowing.

But in a current study, researchers used trods with the same material. Sticking one electrode into tree, and another in the soil. And they found big leap maple generate a steady bolt up to a few hundred MELIBOLS. That's way in less that bolt in a half provided by stardard w battery.

So the scientist design the gadget was so small with parts just hundred meters in size. But u can on tree power alone. The results appeared in the I-tri transactions on nana-technology. If u r nuts for a renewable energy, u probably can much greener than f tree.

GENE THERAPY CURES COLOR-BLIND MONKEYS

Now, here are(is) sth. we(u) don't c everyday. Scientists cure color blind monkeys. According to a report published online in the Journal Nature, researchers of use(have used) gene therapy to allow color blind squirrel monkeys to look at their food(fruit) in a whole new like(light). In one type of squirrel monkey, the males like(lack a) visual pigment called L-opsin, its absence (renders) the monkey's color blind, unable to distinguish reds and greens. Most the females on the other hand, see and(in) full color. So the scientists got to wondering what would happen if they give(gave) a boy squirrel monkey the same up as the(opsin that) girls have.

MINI T. REX RECOVERED

Asking any young dinosaur phonic(fanatic) about the mighty Tyrannossaurus rex and (we'll) probably get (a) fairly accurate description: huge reptile, big head, powerful jaw, high(tiny) little arms. Scientists had thought the dino(that the) animal evolved its bizzare proportions as group(it grew to its gargantuan) stature. But in this week's issue of the journal Science, paleontologist Pall Sereno discribes a newly discovered miniature tyrannosaurid that evolved millions of years earlier and has all the attributes of the larger one.

The tiny dinosaur had been excavated in Mongolia illegally insult(and sold) to (a) private collector. He contacted Sereno to evaluate the preserve(d) tyrannosaurid. Sereno agreed to do so if the dinosaur was donated to science, and eventually returned to China.

The dinosaur is about 9 feet long and it has(had) estimated weight of only 150 pounds, but it's all there: the tiny arms, the huge head, the large teeth, the(and) muscular jaw. 125 million years later, that animal(')s descendant(s) has bloomed(had ballooned) into (an) almost exact replica more than 90 times larger.

HOW TO STOP THE ONGOING LOSS OF SPECIES

Species of plants, animals, and other categories of living things r disappearing. (And) Millions of people still live in an(\) extreme poverty. But is there (a) collection? EG, is the ongoing destruction of the indonesian rain forest driven by economical development of the(\) Indonesians, or (is) the global domain what(demand for wood) products to plan(blame?). Is it a combination, or (are there) other factors that r more important(?) The bad news is that answer is unclear, and the worse news is that the world's countries have not lived up to the pledge of conventional(under the convention on) biological diversity to reduce the rate of species lost(loss) by 2010.

One reason for that failure, no one is agree(has agreed) on what (are) true indicators with(of whether) biodiversity (is) being preserved or lost. So argues that will pull the(Matt Walpol of the) UN Envrionment Programme in this week's issue of the journal Science.

What is clear is that approaches look(an approach that looks at both) biodiversity in(and) poverty is going to be needed.

LISTENING WHILE DRIVING IS, WHAT'D YA SAY?

We all know that talking on our(a cell) phone can impair our ability to drive. Although too many of us do this that way(it anyway). Now a study in the Journal Psychonomic Bullitin in(and) Review, shows (that the) reverse is also true: Driving makes it hard to keep track of what we r talking about.

Previouse studies (had) found that motorists (r able to) converse just fine, but to Gary Dell (of) the university of Illinois that fining just did(n't) make sense, because comperhending speech requires attention, as does during family's dam(steering the family sedan). So Dell (did a) study in driving simulator.

96 participants were paired up, with one take the will(taking the wheel) while the other take(sat in) the passenger seat or talk(ed) to the driver on (a) hands-free phone. Each participant listened to and was asked to repeat a handful of stories, and then to remember the(them after) getting (out of) the car.

Superconductors carry electricity with no lost(loss to) resistence. There r too(to) regular conductors with(what a) laser beams meet the(is to a) light bulb. The problem is they have to be cool(ed) to at least -100 degrees celsius to work. Then (the) electrons spontaneously start moving from(in) one direction in(and) forming pairs.

SEX DIFFERENCES IN JEALOUSY

Studies from around the world (have) reported that men r much more jealous for(of) sexual infidelity than emotional infidelity.

And express(Experts) often lean on (an) evolutionary cause for this: Men can never be sure felt(they r) the baby daddy, and women r most concerned with securing a genuiely lawyer(loyal) father to care for the children.

We r often use(Well, authors of) a recent study in Psychological Science quesiton the string(strength) of the evolutionary just so secret(theory), realizing that there'r men who find emotional cheating far worse than sexual cheating. The study reports that personality patterns, shiped(shaped) by one's relationship history can have (an) impact on jealousy.

For 100(Over 400) participants took service(a survey) to measure the(ir) jealousy type, meaning which trouble is the(troubles them) more: sexual or emotional fidelity. And(Then) they completed the test with(which) specifically measures attachment style (in) relationships with new(those) styles include secure, fearful, preoccupied, or dismissing. And they found that 65% of those who were attornymouse(r autonomous and) tend to be dismissive about commitment reported greater stress about sexual cheating than emotional cheating.

Even within each sex without restriking(the results were striking), dismissive women were 4 times more likely to report greater sexual jealousy than securely commited women.

ASEXUAL SOLUTION TO A PARASITE PROBLEM

O(rganisms) evolve(d) with sexual reprodution so they can(could) stay one step (ahead of) parasites. Also they(Or so the theory) goes, but what about the(\) beasties make baby without sex? How do they escape infection? A study in the Journal Science suggests that for Bdelloid Rotifers, the answer is blowing in the wind.

Biologists believe the(that) sex offers (an) evolutionary advantage because it promotes genetic diversity. Coming up with fresh new gene combinations should allow organism to outsmart parasites, which (r) also could(\) continuously evolving. But if it(that theory) is correct, then Bdelloid Rotifers, fresh water and VB(invertebrates that) have(n't) had sex (in) at least 13(30) million years, should parasite(have been parasited) into extinction long ago. Yet here they are, alive and well.

To find out why, scientists infected Rotifers with (a) deadly fungus. And they found that Bdelloid Rotifers can shifted(shaked) the infection by drying out, drifing away and (then) rehydrating once the(y) land someplace moist, but the fungi were free(fungus-free).
