Evolution Library. Beauty and Brains: Award-Winning Medical Images. Leaf of Lavender This false-coloured scanning electron micrograph (SEM) shows a lavender leaf (Lavandula) imaged at 200 microns. The surface of the leaf is densely covered with fine hair-like outgrowths made from specialised epidermal cells called non-glandular trichomes.
Frog Oocytes This confocal micrograph shows stage V-VI oocytes (800-1000 micron diameter) of an African clawed frog (Xenopus laevis), a model organism used in cell and developmental biology research. Each oocyte is surrounded by thousands of follicle cells, shown in the image by staining DNA blue. Blood vessels, which provide oxygen to the oocyte and follicle cells, are shown in red. The ovary of each adult female Xenopus laevis contains up to 20 000 oocytes. A Cancer Cell Divides This composite confocal micrograph uses time-lapse microscopy to show a cancer cell (a HeLa cell derived from the cancer of a woman named Henrietta Lacks) undergoing cell division (mitosis).

Bee Mimics, BeeSpotter, University of Illinois. Take a look at the three pictures below, and try to identify which are bumble bees and which are honey bees: If you didn't pick any of them - good job! None of the insects pictured above are bees, but actually flies that are mimicking bees (or, in the case of the first picture, mimicking a wasp).
Thanks to cartoons and advertisements (not to mention the pain of an unexpected sting), bees are well-known insects in the public mind. And as a result, when most people think of a bumble bee or a honey bee, they're not too far off-target. These bees are flying insects, often hairy, and can have black and yellow stripes. However, bumble bees and honey bees represent only a handful of the bee species in the world, or even Illinois. Identifying Bumble Bees and Honey Bees Honey bees and bumble bees share many features, but it's not too hard to tell them apart. Honey bees have black and orange-yellow stripes, while bumble bees have black and vivid yellow stripes.

Agricultural land (% of land area) in India. Honey Bees & Other Pollinators | Agriculture Defense Coalition. Honey Bees and other pollinators are in sharp decline in the United States and around the world. There are many competing theories for these declines. And there are slow, ongoing investigations into these declines. Honey Bee decline (called Colony Collapse Disorder CCD), has been increasing each year. And this decline, along with the decline of numerous other pollinators, will start to reduce food supplies from lower agriculture crop production, reduce the number and variety of herbs, flowers and tree crops.
We depend upon pollinators for the wonderful variety of foods and colors which we take for granted most of the time. We are introducing genetically engineered plants into our environment which may contribute to the declines. Many universities, government agencies, and others are investigating the declines. Neonicotinoids showed up about the same time as the Honey Bee decline started. Silence of the Bees premiered on PBS October 28, 2007. 7 1 2010 U.S. 6 Women Scientists Who Were Snubbed Due to Sexism. In April, National Geographic News published a story about the letter in which scientist Francis Crick described DNA to his 12-year-old son. In 1962, Crick was awarded a Nobel Prize for discovering the structure of DNA, along with fellow scientists James Watson and Maurice Wilkins. Several people posted comments about our story that noted one name was missing from the Nobel roster: Rosalind Franklin, a British biophysicist who also studied DNA.
Her data were critical to Crick and Watson's work. But it turns out that Franklin would not have been eligible for the prize—she had passed away four years before Watson, Crick, and Wilkins received the prize, and the Nobel is never awarded posthumously. But even if she had been alive, she may still have been overlooked. Like many women scientists, Franklin was robbed of recognition throughout her career (See her section below for details.)

7 Theories on the Origin of Life. By Charles Q. Choi, Live Science Contributor | March 22, 2011 04:05pm ET Credit: NASA/JPL Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup? Here are science's theories on the origins of life on Earth.
Author Bio Charles Q. Charles Q. Charles Q. Job. Lectures. University. THOR HEYERDAHL EXPEDITIONS and ARCHAEOLOGY OF THE PACIFIC PEOPLES. And Early Life Thor Heyerdahl is a world-renowned explorer and archaeologist. He was born in 1914, in Larvik, Norway. From his earliest days, he was an enthusiatic nature lover, and he was inspired by his mother (who was head of the local museum) to take an interest in zoology and nature. While still in primary school, he ran a one-room zoological museum from his home. Mr. Heyerdahl later enrolled at the University of Oslo, where he specialized in zoology and geography until leaving on his first expedition to Polynesia in 1937-1938. The First Expeditions to Polynesia (1937-38) and Northwest America (1940-41) Arriving in Polynesia, the young student Heyerdahl and his bride Liv were adopted by the supreme Polynesian Chief of Tahiti, Teriieroo in 1937.
Abandoning his study of zoology, Heyerdahl began an intensive study of testing his theory on the origins of the Polynesian race and culture.

A bit of green :: Crafts :: Plastic Cup Lamp. Now that my university is closed for winter holidays, I finally have more free time to do all the crafty things I’ve been wanting to. One of these is a lamp made from plastic cups I’ve seen at taf, the art foundation, in the Monastiraki region in the center of Athens.
When I first saw it at taf, I was amazed; I looked closely and I couldn’t believe my eyes! The object itself is so peculiar, modern and alien-like it could be in any design exhibition. With my best friend’s birthday coming up, I decided to make it myself and give it to her as a gift. Disclaimer: There have been some concerns about the safety of this construction (see the comment of user “when” below for example).
I only needed a couple of things: 200-250 large plastic cups (recyclable, at least )600-700 staplesa staplera lamp socket, lamp cord and plug – mine came from a broken IKEA lamp! That’s all you will need. Start stapling the cups together as shown. Staple again and again and again… Until your lamp goes from this… PHIL PLAIT: Welcome to science. Phil Plait, better known as The Bad Astronomer, is an astronomer (obviously), noted skeptic and popular science writer. His Bad Astronomy blog is one of the most popular science websites around and it’s where I get my regular science fix.
This quote is taken from a speech Plait gave at a student science fair. He had no idea what he was going to say until he saw a news story on television the night before the fair. The story was a typical psuedo-science fluff piece that’s unfortunately seen too often on mainstream news. It made Phil so angry he quickly wrote this speech in response. Phil has been one of Zen Pencils biggest supporters and he’s responsible for making my Carl Sagan comic go viral. . – 50% of profits from this print will be donated to Phil’s favourite charity Every Child By Two, a vaccine advocacy group. – I also turned the caricatures of Newton, Einstein and Feynman into a special ‘Rockstars of Physics’ print!
Animal Sleep. Most animals have a daily pattern of rest and activity. Some animals are more active during the day (diurnal) and some are more active during the night (nocturnal). How much time do animals spend sleeping? Well, it depends on the animal: References: This table was adapted from four sources: Aserinsky, E., Eyelid condition at birth: relationship to adult mammalian sleep-waking patterns, In Rapid Eye Movement Sleep, edited by B.N.
GPS. Topology - GIS Dictionary. Which trap type and trap color work best in collecting different groups of bees (Family: Apidae) and pollinating flies (Order: Diptera)? Wednesday, November 16, 2011: 9:35 AM Room A18, First Floor (Reno-Sparks Convention Center) Mark A. Schlueter , School of Science and Technology, Georgia Gwinnett College, Lawrenceville, GA Nicholas G. Stewart , School of Science and Technology, Georgia Gwinnett College, Lawrenceville, GA It is useful to know which traps are most effective in collecting both the highest possible diversity as well as the most individual specimens. Variations in trap type, elevation, and color all play a role in the success of the sampling method. Natural History Museum. Researchers take novel approach to honey bee plight. Iowa State University is taking a team approach in studying what is behind the disappearance of honeybees known as "Colony Collapse Disorder.
" Amy Toth, assistant professor in Iowa State's ecology, evolution and organismal biology department, was awarded an Agriculture and Food Research Initiative grant by the U.S. Department of Agriculture to explore the importance of nutritional stress and viruses on honeybee health. She is working with researchers Allen Miller and Jimena Carillo-Tripp in the plant pathology and microbiology department and Bryony Bonning in the entomology department. "We're taking a novel approach to studying the colony collapse phenomenon," Toth said. "A lot of scientists are looking at viruses or nutrition or pesticides; our approach is the interaction among many factors and evaluating how they all work together.
" Colony Collapse Disorder was recognized in 2006, but Toth said honeybees have been in trouble for decades. The effects of colony collapse are sudden. Plant Ontology - flower nectary - Terms | NCBO BioPortal.
