The elusive octopus genome has finally been untangled, which should allow scientists to discover answers to long-mysterious questions about the animal's alienlike physiology: How does it camouflage itself so expertly? How does it control-and regenerate-those eight flexible arms and thousands of suckers? And, most vexing: How did a relative of the snail get to be so incredibly smart-able to learn quickly, solve puzzles and even use tools?

11 video Hank brings us the story of Gregor Mendel, the Austrian monk who, with the help of a garden full of pea plants, discovered the fundamental properties of inheritance and paved the way for modern genetics. He also gives us the dirt on a scientific scandal that has followed Mendel beyond the grave.

In 2007, researchers discovered that people with a common variant of FTO tend to be heavier than those without it. Since then, studies have repeatedly confirmed the link. On average, one copy of the risky variant adds up to 3.5 extra pounds of weight. Two copies of the gene bring 7 extra pounds - and increase a person's risk of becoming obese by 50 percent.

The physical connection between mother and fetus is provided by the placenta, an organ, built of cells from both the mother and fetus, which serves as a conduit for the exchange of nutrients, gasses, and wastes. Cells may migrate through the placenta between the mother and the fetus, taking up residence in many organs of the body including the lung, thyroid, muscle, liver, heart, kidney and skin. These may have a broad range of impacts, from tissue repair and cancer prevention to sparking immune disorders.

This lesson follows a flipped learning model where teachers don't stand before the class and lecture.  Instead, students become grizzly bear scientists and "discover" the answers to real-world research questions through scientific inquiry. Using real-world demographic data collected over 30 years on grizzly bears in the Greater Yellowstone Ecosystem, students work individually, in three Science Teams, and as a class to determine whether or not this grizzly bear population is biologically ready for delisting.

Students will use pineapple juice as an enzyme and Jell-O™ as a substrate to illustrate an enzyme/substrate complex. Students will discover that the processing of food will denature enzymes.

The most venomous animal on the planet isn't a snake, a spider, or a scorpion; it's a snail-a cone snail, to be precise. The Conus genus boasts a large variety of marine snails that have adopted an equally diverse assortment of venoms. Online today in the Proceedings of the National Academy of Sciences, researchers report an especially interesting addition to the animals' arsenal: insulin. According to the paper, this marks the first time insulin has been discovered as a component of venom.

A worldwide study of the DNA of 100,000 women has discovered two new genetic variants associated with an increased risk of breast cancer. The genetic variants are specifically linked to the most common form of breast cancer, oestrogen receptor positive, and provide important insights into how the disease develops.

Scientists discovered a new retrovirus "fossil" found in the common vampire bat which is homologous to retroviruses in rodents and primates. The results suggest the recent circulation of an active infectious retrovirus and cross-species transmission. The study has been published in the scientific journal Journal of Virology.

Inthis lesson students will enter the world of the genome, learning about humanhistory and evolution by examining information about human, Neanderthal, andchimpanzee DNA. Using web interactives and videosfrom The Human Spark, studentswill be introduced to the ambitious Human Genome Project, learn about thegenetic similarities and differences between human beings and our hominidancestors, explore how specific genes manifest themselves in differentorganisms, and discover how genetic information can help us trace a path ofhuman migration all the way back to our earliest ancestors.

31min video  The epic voyages of Darwin and Wallace led each to independently discover the natural origin of species and to formulate the theory of evolution by natural selection.

7:00 video: This film is the first of a two part series on the evolution of new genetic information. Here we focus on Point Mutations - the simplest natural mechanisms known to increase the genetic information of a population. Our second film of the series will focus on duplication events - natural mutations that increase the total amount of genetic information of an individual. This film was produced under the guidance of molecular biologist Dr. Nicholas Casewell. http://www.lstmed.ac.uk/about/people/... Point mutations are small, natural edits in the DNA code of an individual. These edits can be passed from parent to child. Because they are mere edits, point mutations usually do not increase the total amount of information in an individual. As new information is gained, old information is lost. Point mutations do, however, increase the total amount of information within a population. In this film you will see several examples of beneficial point mutations which have enhanced a creatures abilities or even given rise to entirely new abilities. The first two examples were directly observed in bacteria by scientists in the lab. The third is a case found in domestic dogs, the last example was discovered in several species of wild animal.

Join the Amoeba Sisters in discovering how to use a dichotomous key to identify organisms. This video also touches on the importance of scientific names.

This case study presents the fictional tale of two neighboring towns that have recently experienced a growth boom and are now suffering the environmental consequences. The case provides an opportunity to explore a wide variety of anthropogenic causes of natural capital degradation. Students are assigned the role of scientists working for the regional Department of Environmental Resources Management, and it is their job to discover the underlying causes for a wide variety of citizen complaints and to suggest reasonable and cost effective solutions. The case may be assigned as a recap activity after teaching a unit on natural capital degradation. The case includes a PowerPoint presentation as well as three lab activities that are included in the teaching notes. The case would be appropriate for high school or lower level undergraduate ecology or environmental science courses.

More than 1,600 people worldwide have been infected with Middle East Respiratory Syndrome, or MERS, and complications from it have resulted in nearly 600 deaths. But in the three years since scientists identified the disease, they haven't been able to discover a way to treat or prevent infection. Now a team of international researchers has used genetically modified cows to create antibodies that combat the disease, which could mean that a vaccine might soon be possible. The research was published today in Science Translational Medicine.

Rosalind Franklin was a British scientist who helped discover the structure of DNA, but you most likely haven't heard of her. Hank will attempt to fix this gap in your knowledge on today's SciShow: Great Minds.

Could you tell your friends where to find food just by dancing? Join Ross Exton of the Live Science Team as he takes a look inside a hive to discover the mysterious behaviour of honey bees.

What an incredible transformation. A protein used to help bones mend can also force pancreatic cells into producing insulin. The discovery could help people with type 1 diabetes produce their own insulin without having to take daily injections. In type 1 diabetes, beta cells in the pancreas that make insulin - the hormone that keeps our blood glucose levels at a safe concentration - are destroyed by the immune system. As a result, people with the disease have to inject themselves daily with insulin. Now, researchers have discovered that non-beta cells in the pancreas can be transformed into insulin-producing cells, merely by exposing them to a growth factor called BMP-7.

In 2012, the World Health Organisation classified colistin, the most widely used polymyxin, as being critically important for human health. But that didn't stop farmers around the world, especially in China, from using large quantities of colistin to fatten up pigs and chickens. Now Yi-Yun Liu at the South China Agricultural University in Guangzhou and colleagues have discovered the first known resistance gene for colistin that is able to move freely from one bacterium to another.
