Distant galaxy plows through cluster of others, with baby stars in tow
Fires cause billions of dollars of destruction to homes and forests every year. But not all fires are bad, especially for forests. With a better understanding of fire, scientists can both help people prevent dangerous fires — and identify which ones it would be better to let burn.
SCIENCEBefore reading:1. Describe at least three ways fire plays a direct or indirect role in your everyday life.2. Provide some examples of fire safety measures in place in your home or school.During reading:1. What is forest litter?2. How can a fire create a break in a forest?3. Explain how a fire can benefit a forest.4. List three tools used by fire experts at the Southwest Research Institute.5. Why did the Hindenburg explode and burn?6. Why are fire safety experts interested in lithium-ion batteries?
The secret of fire: Prometheus to pyrolysis
Clean drinking water could be only a tree branch away, a new study finds.
An experiment with beads offers support for the claim that a rare type of lightning may accompany some quakes.
Forty talented high-school seniors competed in the 2014 Intel Science Talent Search this week, sharing $630,000 in prizes. Top prize went to a teen for his new approach to fighting flu.
A study finds that the viruses and parasites that plague honeybees can infect bumblebees too, sickening another important pollinator.
Disease diagnosis often requires expensive equipment and tests to probe deep inside the body. But a new test relies on a fast, cheap and easy technique. And its answers appear on a strip of paper — just as they do on a pregnancy test.
A novel material can alter how easy it is to change data stored on it, based on temperature. One immediate application: more secure hard drives for computing.
A new map may explain why some brain injuries are worse than others. Even relatively minor injuries that disrupt message superhighways may have a more devastating impact than some seemingly catastrophic injuries.
By neutralizing the poison produced by fire ants, ‘crazy’ ants can survive heated battles. And that may help explain why crazy ants are edging out fire ants in parts of the southern United States.
Boys develop autism at four times the rate seen in girls. Girls’ genes are better protected from the mutations linked to this brain disorder, data now suggest.
SCIENCEBefore reading:1. How do you think moviemakers decide how dinosaurs such as those in Jurassic Park should appear and move?2. List three types of ancient animal remains other than bones.During reading:1. Which dino do scientists believe was the largest to ever walk Earth? How much did it weigh?2. What is a sauropod?3. Name two types of technology Manning’s team used to create a three-dimensional model of the Argentinosaurus skeleton.4. Explain why Manning’s team had to choose carefully how many moving parts their 3-D dino would have.5. Why did Manning’s team place most of the muscles on the rear legs of the Argentinosaurus 3-D model?6. How fast did Argentinosaurus walk, according to the researchers’ model? Does this number surprise you? Explain your answer.7. What is a trackway?
With the help of computers, researchers are getting a pretty good idea of how these ancient creatures moved, walked and ate.
It’s the first time astronomers have ever detected a cluster of stars moving collectively at such speed.
Everything making up Earth and what’s now living upon it — from trees and people to our pets and their fleas — owes their origins to the elements forged by ancient stars.
SCIENCEBefore reading:1. Humans and aliens may look worlds apart. But are they made of the same stuff? Explain your answer.During reading:1. Name two types of situations in which stars create elements and fling them out into space.2. How many elements occur naturally on Earth?3. How are an atom and a solar system alike?4. Which element has the fewest protons, and so is considered the lightest? Which element is the heaviest?5. Name three elements and where each occurs abundantly.6. About how long ago did the Big Bang occur and how long did it last?7. What do scientists mean when they say the universe is expanding?8. Which two elements were around shortly after the Big Bang? How were heavier, later elements created?9. What pulls gas molecules in giant gas clouds toward each other?
Woolly mammoths roamed the Arctic until about 10,000 years ago. Why they died out may trace to the vanishing of the mostly flowering plants on which they had been dining.
Many companies have moved the plants that make their products to developing countries, such as China. But the pollution linked to making those products can travel around the world.
