What Makes A Bee A He Or A She?

What Makes A Bee A He Or A She?
Three years ago, scientists pinpointed a gene called csd that determines gender in honey bees, and now a research team led by University of Michigan evolutionary biologist Jianzhi "George" Zhang has unraveled details of how the gene evolved. The new insights could prove useful in designing strategies for breeding honey bees, which are major pollinators of economically important crops-and notoriously tricky to breed.

The findings of Zhang and........Go to the Science-blog (Added on 10/27/2006 4:40:08 AM)

200-million-year-old Baby Galaxies

200-million-year-old Baby Galaxies
Astronomers have taken amazing pictures of two of the most distant galaxies ever seen. The ultradeep images, taken at infrared wavelengths, confirm for the first time that these celestial cherubs are real. The researchers* are now able to weigh galaxies and determine their age at earlier times than ever before, providing important clues about the evolutionary origins of galaxies like our Milky Way. The work appears in the October 1 issue of........Go to the Astronomy-blog (Added on 10/26/2006 5:04:37 AM)

World's Most Intense Thunderstorms

World's Most Intense Thunderstorms
A summer thunderstorm often provides much-needed rainfall and heat wave relief, but others bring large hail, destructive winds, and tornadoes. Now with the help of NASA satellite data, scientists are gaining insight into the distribution of such storms around much of the world.

By using data from the NASA Tropical Rainfall Measuring Mission (TRMM) satellite, researchers identified the regions on Earth that experience the most intense........Go to the Science-blog (Added on 10/26/2006 4:48:23 AM)

The Space Tourism Industry Can Really Make Money

The Space Tourism Industry Can Really Make Money
So far, only one craft has flown in space, sending test pilots to the final frontier at an expense of $25 million-plus to win the $10 million Ansari X Prize. Market right now doesn't show the prospects that were expected by the investors in the space tourism industry.

But this doesn't mean that people in the real world don't have any respect for this industry. Space Tourism is not aimed at "space geeks" only. This seems the way it is because........Go to the Astronomy-blog (Added on 10/25/2006 5:02:58 AM)

Amazon River Reversed Flow

Amazon River Reversed Flow
Ask any South American dinosaur which way the Amazon River flows and she would have told you east-to-west, the opposite of today. That's the surprising conclusion of researchers studying ancient mineral grains buried in the Amazon Basin.

The once westward roll of what is now the world's largest river was caused by a long-gone highland near what today is the river's mouth. That highland was created by the breaking away of South America from........Go to the Science-blog (Added on 10/24/2006 8:19:26 PM)

Electronic Chip Interacting With The Brain

Electronic Chip Interacting With The Brain
Researchers at the University of Washington (UW) are working on an implantable electronic chip that may help establish new nerve connections in the part of the brain that controls movement. Their most recent study, would be published in the Nov. 2, 2006, edition of Nature, showed such a device can induce brain changes in monkeys lasting more than a week.

Newton's Apple Tree Bears Fruit
Ed Vetter (S.B. 1942) gave MIT an apple tree that is a direct descendant of the tree under which Isaac Newton sat when he is said to have conceived the theory of gravity.

"I couldn't think of a better place than MIT to put a tree that illustrates a law of physics," says Vetter, whose tree stands in MIT's President's Garden, a sunny spot off the Infinite Corridor.

Could Dreams Be A Mechanism To Help Us Prepare For Danger?

Could Dreams Be A Mechanism To Help Us Prepare For Danger?
Dreams have been interpreted in a number of different ways through the ages: as messages from the gods, repressed sexual fantasies. or, based on an evolutionist approach that emerged around the turn of the millennium, as a mechanism that helps us to prepare survival strategies in the face of danger.

A seven year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass, governed by a gravitational billiard ball game between stars. Heavier stars slow down and sink to the cluster's core, while lighter stars pick up speed and move across the cluster to its periphery.
