Explore some examples of specialized plant and animal cells with the Amoeba Sisters! This video explains how specialized cell structure suits their function.

How do cells in your body differentiate into other types of cells? Explore cell specialization featuring stem cells and the role they play in cell differentiation.

But this tiny sample turned out to hold tremendous scientific value. It was from a person fortunate to survive the deadly Ebola virus outbreak of 2014. Walker and her colleagues wanted to know if they could identify some special antibodies in that person's blood. If this person had special Ebola-neutralizing antibodies, that might help explain why that person lived. The antibodies might also help provide a template for future development of a vaccine. Or, they could be the basis for genetically engineered copies that could be manufactured at large scale, stockpiled and used to rescue people newly infected in an outbreak.

We see color because of specialized light-sensing cells in our eyes called cones. One type, L-cones, sees the reds of strawberries and fire trucks; M-cones detect green leaves, and S-cones let us know the sky is blue. But vision scientists have now discovered that not all cones sense color (see video).

U.S. researchers have found that Zika can attack special populations of brain cells in adult mice in the part of the brain involved in learning and memory, raising new questions about how the virus may be impacting millions of adults who have been infected with the virus. The findings, published on Thursday in the journal "Cell Stem Cell," are the first to look at whether Zika can attack the same kinds of cells in adult mice that they do in fetal mice.

The premise of Assassin's Creed is the reliving of other people's memories stored inside DNA. Well scientists have found that in mice, it actually happens! Anthony is joined by special guest and our friend Tara Long from Hard Science to explain how this process works, and if it might apply to humans as well.

"CRACKING THE CODE"/"Cloning Paper Plasmid" activities can (1) serve as a review of the "genetic code" and the role it plays in our life; and, (2) to help students see how genes may be manipulated for genetic research, namely, gene cloning/genetic engineering. The laboratory time, the specialized equipment and expertise to carry out recombinant DNA experiments may be lacking in the high school. Activity 2 will help students conceptualize the mechanics involved in cutting and ligating DNAs into a plasmid vector with "sticky ends" of complementary DNA base pairs.

1:30 animation As a human embryo develops, its cells become progressively restricted in the types of specialized cells that they can produce. Inner cell mass (ICM) cells of the blastocyst can make any type of body cell. Gastrula-stage cells can give rise to the cells of a given germ layer. Later, cells become even more restricted. For example, the pancreatic bud of the endoderm layer can only make the cells of the pancreas.

Adverse life experiences, particularly those in childhood, contribute to disease morbidity and mortality [1, 2, 3, 4, 5, 6, 7]. There is considerable interest in understanding the mechanisms through which they do so, as it remains unclear how illness becomes apparent decades after the presumed initiating event. Long-standing hypotheses include chronic activation of the hypothalamic-pituitary-adrenal axis [8, 9, 10] and alterations of neuroimmune function [11]. Molecular signatures of stressful life experiences and their relation to disease are therefore of special interest to clarify the causal relationship between signature, disease, and stress.

Here you will find a collection of the best scientific documentaries available online. Focus here is on quality above quantity. There is an endless heap of documentaries that are "scientific" but in fact are not, instead filled with metaphysical ideas, UFOs, bio energies and other meta-sciences. You will not find those here. Other thing is the quantity of information in every documentary itself, often being very low but instead full of special effects and dramatic monologue. Hopefully you won't find those here either.

2:18 Human embryonic development depends on stem cells. During the course of development, cells divide, migrate, and specialize. Early in development, a group of cells called the inner cell mass (ICM) forms. These cells are able to produce all the tissues of the body. Later in development, during gastrulation, the three germ layers form, and most cells become more restricted in the types of cells that they can produce.

BBC online art gallery  The Science and Art slideshow is one of five slideshows produced specially to give teachers ideas about how to use Your Paintings in the classroom.  Your Paintings brings together paintings owned by public galleries in the UK. As the paintings are in public ownership, ultimately everyone living in the UK owns this vast collection.  As well as containing many portraits of important scientists, Your Paintings can be used as a starting point for pupils to make scientific investigations of their own.

The Birds-of-Paradise Project reveals the astounding beauty of 39 of the most exquisitely specialized animals on earth. After 8 years and 18 expeditions to New Guinea, Australia, and nearby islands, Cornell Lab scientist Ed Scholes and National Geographic photojournalist Tim Laman succeeded in capturing images of all 39 species in the bird-of-paradise family for the first time ever. This trailer gives a sense of their monumental undertaking and the spectacular footage that resulted.

Bowhead whales (Balaena mysticetus), denizens of Arctic seas, are known to live more than 200 years, yet they show few signs of the age-related ailments that plague other animals, including humans. Even the bowhead's closest cetacean relative, the much smaller minke whale, lives only 50 years. That suggests the larger whales (which have more than 1000 times as many cells as humans) have evolved some special natural mechanisms that protect them against cancer and aging.

Within every cell in our body, two copies of a tumor suppressor gene called BRCA1 are tasked with regulating the speed at which cells divide. Michael Windelspecht explains how these genes can sometimes mutate, making those cells less specialized and more likely to develop into cancer.

Scientists once shied away from naming research animals, and many of the millions of mice and rats used in U.S. research today go nameless, except for special individuals. But a look at ​many facilities suggests that most of the ​other ​891,161 ​U.S. ​research animals ​have proper names​, including nonhuman primates, dogs, pigs, rabbits, cats, and sheep​.

Beneath your ribs, you'll find, among other things, the pancreas -- an organ that works a lot like a personal health coach. Emma Bryce explains how this organ controls your sugar levels and produces a special juice that releases the nutrients from your food to help keep you in the best possible shape.
