A Contagious Cancer Is Spreading Among Several Shellfish Species. A contagious, leukemia-like cancer is spreading among several species of cockles, clams, and mussels.
It’s known as disseminated neoplasia, and according to a new Nature study, it appears to be directly transmitted between different species of marine bivalves – likely through the water. Most cancers arise from changes and mutations that accumulate in the genomes of cells over time. And while cancer cells can migrate, or metastasize, they usually remain in that one individual. Until recently, we only knew of two examples of transmissible cancer in the wild: a venereal tumor that affects dogs and the Tasmanian devil facial tumor disease. Last year, researchers studying soft-shell clams (Mya arenaria) along the US east coast found that cancerous tumor cells are being passed from one clam to another. Huge New Study Reveals The Impact Of Spanking On Children.
The appropriateness of spanking as a parental disciplinary technique arouses passionate debate.
But a new meta-analysis of five decades of research suggests that, in addition to the psychological effects on children, there may be a large price to pay for the parents. Watch Physicist Brian Greene Explain Gravitational Waves To Stephen Colbert. Theoretical physicist Brian Greene makes an appearance on The Late Show with Stephen Colbert, where the two banter about the historic discovery of gravitational waves on September 14, 2015.
Turns out, Greene only needs eight minutes to give a crash course lesson on gravitational waves and Albert Einstein's 100-year-old theory, all in layman’s terms. As Greene explains, gravitational waves are essentially ripples in the fabric of space-time. By using laser models, he expands on this definition to show how the twin LIGO detectors independently found evidence for gravitational waves from two merging black holes more than a billion light-years away.
'Almost too late': fears of global superbug crisis in wake of antibiotic misuse. If You Give A Man A Gun: The Evolutionary Psychology Of Mass Shootings. Harvard contro i latticini nuove conferme che sfatano il mito. Brazilian Wasp Venom Kills Cancer Cells, But Not Healthy Cells. Wasps get their fair share of bad press. They have painful stingers, and they're not as useful (or cute) to us as bees. However, their time to step in the spotlight may be just around the corner: Their venom has been shown to attack cancer cells while leaving healthy cells alone. The cancer-targeting toxin in the wasp is called MP1 (Polybia-MP1) and until now, how it selectively eliminates cancer cells was unknown. According to new research, it exploits the atypical arrangement of fats, or lipids, in cancer cell membranes. A Quick Guide to Spotting Graphics That Lie.
Liberal or conservative? It may be down to your genes. A study by the National University of Singapore, found that a specific variant of the gene DRD4, dubbed the “adventure gene” and which is involved in our risk taking and decision making processes, may determine how we vote.
The research published by the Royal Society and led by Richard P. Ebstein and Chew Soo Hong surveyed over 1,700 Singaporean Chinese undergraduates from NUS to find out whether they identified as liberal or conservative. Blood and DNA samples were also taken from the students and compared to their surveys. Everyone has the DRD4 gene but the tests revealed that less that 50 per cent of the participants had the variant of the gene which is associated with high risk behaviours and attitudes. Il sonnellino pomeridiano fa male, a dirlo una ricerca australiana. “Maybe Time Doesn’t Even Exist” X-chromosome SNP analyses in 11 human Mediterranean populations show a high overall genetic homogeneity except in North-west Africans (Moroccans) This Is What Happens To Your Brain When You Don’t Sleep. Feeling sleepy?
It’s no secret that a good night’s sleep is key to a good day. Yet, according to the Institute of Medicine, an estimated 50-70 million adults in the United States have sleep difficulties. The infographic below from Science.Mic uses information from the CDC, International Journal of Occupational Health and Medicine and the UC Berkeley Walker Sleep Lab to explain the side effects of not getting the recommended 7-8 hours of sleep at night. These side effects include loss of memory, heightened anger, food cravings, hallucinations and loss of memory. Researcher says no evidence children of same sex couples negatively impacted. A new study from the University of Colorado Denver finds that scientists agree that children of same-sex parents experience 'no difference' on a range of social and behavioral outcomes compared to children of heterosexual or single parents.
The study was led by Jimi Adams, an associate professor in the Department of Health and Behavioral Studies at CU Denver College of Liberal Arts and Sciences, and published this month in Social Science Research. The research comes at a time when the U.S. Supreme Court is determining whether the Constitution requires marriage equality. Is Depression a Mental or Physical Illness? Unravelling the Inflammation Hypothesis.
Most people feel down, tired and inactive when they’re injured or ill.
This “sickness behaviour” is caused by the activation of the body’s immune response. It’s the brain’s way of conserving energy so the body can heal. This immune response can also occur in people with depression. Experience Just How Big the Universe is, in One Mind-Blowing Interactive. This is the smallest unit of scale in the universe.

Dormire poco fa male, smettetela di dire il contrario. Scientists Discover The Body Part Used To Sense The Earth's Magnetic Field. From salmon, to geese, to turtles—many animals move and migrate in relation to the Earth’s magnetic field.
With no obvious sense organ to detect the magnetism, it’s long puzzled scientists as to how they manage this. But a group of researchers from the University of Texas think they may have found the answer. After observing how a type of worm wriggles through soil, it was discovered that they possess a sensor on the end of a particular type of neuron, which allows them to align themselves in the correct orientation. Due to the similarities in brain structure across species, the researchers claim that it’s likely other animals share this sensor too. Why Do Some People Feel The Cold More Than Others? 1 in 20 People Have Hallucinated. About 1 in 20 people in the general population has experienced at least one hallucination in their lifetime that wasn't connected to drugs, alcohol or dreaming, according to a new study.
Researchers analyzed information from more than 31,000 people in 18 countries who were interviewed as part of a mental health survey from the World Health Organization. Participants were asked whether they had ever heard voices or seen things that didn't exist, or if they had experienced a delusion (a false belief), such as the thought that their mind was being controlled or that they were being followed.
The study excluded people who possibly had a psychotic disorder, such as schizophrenia or manic depression, which can cause hallucinations and delusions. Therefore, the findings show that hallucinations and delusions are not always connected to serious mental illness, the researchers said. According to the National Institutes of Health, hallucinations can be normal in some cases. Dr. Why Are So Many People Afraid Of Clowns?
