To fight leukemia, we have to fight on its terms, and that means understanding the nature of the fight for superiority between mutated genes and normal genes, according to a paper that investigated Acute Myeloid Leukemia to understand why leukemic cells are not able to develop normally into mature blood cells.

Stem cells in the bone marrow generate billions of different blood cells each day. The process resembles a production line with genes acting as regulators to control each step of the blood formation. Leukemia arises when the DNA encoding regulators in the stem cells is changed by a mutation. When a mutation occurs in the relevant regulator genes, the finely balanced order of the production line is disrupted with drastic consequences. 

Tropical rabbitfish have devastated algal forests in the eastern Mediterranean Sea and pose a major threat to the entire Mediterranean basin if their distribution continues to expand as the climate warms, according to a new study
in the Journal of Ecology.

The members of the team surveyed more than 1000 kilometers of coastline in Turkey and Greece, where two species of rabbitfish have become dominant since they moved into the region via the Suez Canal.

Hurricane Polo still appears rounded in imagery from NOAA's GOES-West satellite today at 10:15 a.m. EDT  but forecasters expect that to change.

The image showed thunderstorms wrapping tightly around the center of the storm while one broken band of thunderstorms extended to the northwest, while the other appeared on the eastern side of the center and paralleled the southern Mexican coastline.

Polo presents a threat to the coast of southwestern Mexico's coastline. A Tropical Storm Warning is in effect for Punta San Telmo to Playa Perula and a Tropical Storm Watch is in effect for west of Playa Perula to Cabo Corrientes.

The Tambora volcanic eruption in 1815 is famous for its impact on climate worldwide. As a result, the year 1816 was given memorable names such as 'Eighteen-Hundred-and-Froze-to-Death', the 'Year of the Beggar' and the 'Year Without a Summer' because of cold weather and unseasonable frosts, crop failure and famine across Europe and North America. 

Some even claim the conditions inspired literary works such as Byron's 'Darkness' and Mary Shelley's Frankenstein.

Anyone who tells you they have a super food or a potion to impact a complex trait is sellinf you something. Life is rarely simple. The things we care about most, from crop yields to disease risks, are instead "complex traits."

Human height is a textbook example of a complex trait while attributes like risk for a particular human disease are shaped by multiple genetic and environmental influences.

The value of the Science 2.0 approach, and the wealth of Big Data that geneticists now have available, is in finding the genes involved and then quantifying their importance when other circumstances are factored in.  

For obvious reasons spaceflight has been reserved for governments and the very wealthy. And when it comes to governments, the criteria are stringent. They will get thousands of applications per year and quickly weed out most of them. Predominantly you have to already be a government employee to have any chance of being an astronaut so that is a big disqualification for much of the best and brightest in America.

In American culture, media and men are criticized for how women feel about their bodies while in Europe women are given more credit for being able to decide for themselves how they feel. 

Europeans may be onto something. A paper in Psychology of Women Quarterly finds that body dissatisfaction among young girls isn't caused by ads for skinny jeans on television or males, it is caused by older girls in schools. 

Most dogs are happy and they are "man's best friend" because they brighten our day. If you rescue a starving dog they will love you forever whereas if you rescue a starving human, in a week they will have decided they did you a favor. With cats, that sentiment lasts until the first meal is over.

But inside, your dog may be more pessimistic, according to a paper from Dr. Melissa Starling of the Faculty of Veterinary Science at the University of Sydney. 

Dogs were taught to associate two different sounds (two octaves apart) with whether they would get the preferred reward of milk or instead get the same amount of water. Once the dogs have learnt the discrimination task, they are presented with 'ambiguous' tones.

While abortion is a common feature of the developed world, there remains some controversy about when it should be allowed. Only the United States and Canada still allow late-term abortion on demand because in the modern world a baby in the third trimester is already clear alive and will remain so with some care. In the third trimester the survival rate in America is 96%, only slightly below full-term children.

Can sound vibrations replace pesticides? Researchers are adapting different eco-friendly methods to try and boost harvests and open up a new chapter in sustainable farming.

Scientists in Northern Italy are experimenting with what they call eco-friendly sound and odor devices to fight off insects from their cultivated fields., though environmental activists don't accept the science of pesticides that have passed registration for 40 years and genetic modification almost as long so believing they will consider sound vibrations friendly is a stretch.
