6 Shockingly Evil Things Babies Are Capable Of. As anyone who's ever encountered babies in the wild can tell you, they're shiftless little balls of deception and greed. Those of us who stand up to walk, and sit down to poop may not be Mother Theresa, but it turns out we had a long way to go from our babbling drooling selves. Yes, unless you're a borderline sociopath today, you were probably at your worst before you ever uttered a word. It's science! It seems crazy that a barely functioning human infant could be cunning enough to lie to get out of trouble, but it's true. Oh shut up, you piece of shit. Perhaps even more surprising is that, when they know they've done something wrong, the little bastards will distract their parents to avoid getting caught. Why Did I Do That?! Lying is considered an important part of a child's development.
According to science, lying isn't something that happens when a normal baby get's corrupted by TV--it is normal human behavior. Pictured: You, if your parents were flightless birds. Survival. The Mind-Blowing World of Human Chimeras. Denisova hominin. Discovery[edit] Tourists in front of the Denisova Cave, where "X woman" was found In 2008, Russian archaeologists from the Institute of Archaeology and Ethnology of Novosibirsk, working at the site of Denisova Cave in the Altai Mountains of Siberia, uncovered a small bone fragment from the fifth finger of a juvenile hominin, dubbed the "X woman" (referring to the maternal descent of mitochondrial DNA,[11]) or the Denisova hominin. Artifacts, including a bracelet, excavated in the cave at the same level were carbon dated to around 40,000 BP.
A team of scientists led by Johannes Krause and Swedish biologist Svante Pääbo from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, sequenced mtDNA extracted from the fragment. In 2011, a toe bone was discovered in layer 11 of the cave, and hence was contemporary with the finger bone.

Physarum polycephalum, also referred as slime molds, belongs to the supergroup Amoebozoa, phylum Mycetozoa, and class Myxogastria. P. polycephalum, often referred to as the “many-headed slime,” is a slime mold that inhabits shady, cool, moist areas, such as decaying leaves and logs.
It is sensitive to light; in particular, light can repel the slime mold and be a factor in triggering spore growth. Characteristics[edit] This protist may be seen without a microscope; P. polycephalum is typically yellow in color, and eats fungal spores, bacteria, and other microbes. P. polycephalum is one of the easiest eukaryotic microbes to grow in culture, and has been used as a model organism for many studies involving amoeboid movement and cell motility. Life cycle[edit] The main vegetative phase of P. polycephalum is the plasmodium (the active, streaming form of slime molds). If environmental conditions cause the plasmodium to desiccate during feeding or migration, Physarum will form a sclerotium.
Want to Rewire Your Brain? Study Music. All those hours practicing the piano pay off big time by biologically enhancing a person's ability to quickly recognize and mentally process sounds that carry emotion, according to a new study. The study, from Northwestern University in Evanston, Ill., offers a new line of evidence that the brain we end up with is not necessarily the same brain we started out with. "We are measuring what the nervous system has become, based on an individual's experience with sound," Nina Kraus, director of the university's groundbreaking Auditory Neuroscience Laboratory, said in a telephone interview. Kraus and a team of researchers attached electrodes to the heads of 30 people, half of whom were serious musicians and half of whom had no significant musical training.
The electrodes measure electricity, "which is, of course, the currency of the nervous system," Kraus said. The participants, wearing earphones, sat in front of a monitor showing nature films with subtitles. Paley's Watch (or the Human Eye) Semen. Spermatozoa, in this case human, are a primary component in normal semen, and the agents of fertilization of the female ova Semen, also known as seminal fluid, is an organic fluid that may contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize female ova. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen is called ejaculation.
Physiological aspects Internal and external fertilization During internal fertilization, however, fertilization occurs inside the female's sexual organs. Composition of human semen The components and contributions of semen are as follows: Roottree. For Leaf-Cutter Ants, Farm Life Isn't So Simple. Leaf-cutting ants and their fungus farms are a marvel of nature and perhaps the best known example of symbiosis, the mutual dependence of two species. But the textbook accounts, it turns out, do not tell even half the story. From research in the past five years the ants' symbiosis has emerged as far more intricate than it appears, involving not two but at least four species, their lives knotted together in a ruthless yet highly successful struggle for survival.
The ants and their agriculture have been extensively studied over the years, but the recent research has uncovered intriguing new findings about the fungus they cultivate, how they domesticated it and how they cultivate it and preserve it from pathogens. For example, the fungus farms, which the ants were thought to keep free of pathogens, turn out to be vulnerable to a devastating mold, found nowhere else but in ants' nests. The ants' achievement is remarkable -- the biologist Edward O.
Repressed memory. Monkeys "Go on Strike" When They Sense Unfairness. November 13, 2007 In recent tests designed to assess monkeys' sense of fairness, a group of brown capuchin monkeys "went on strike" and refused to perform routine tasks when they saw others receiving greater rewards for the same tasks. The more effort the primates used to earn a reward, the more upset they appeared to be at the inequity, according to scientists who conducted the research. "In human terms it doesn't matter how hard you have to work for a million dollars," said lead researcher Sarah Brosnan of Georgia State University in Atlanta.
"But there's a pretty low cutoff point on what you'll do for five. " Building on previous research, Brosnan's team tested six pairs of monkeys on a simple task: handing a token to a human examiner in return for a food reward. When monkeys noticed that their partners received better rewards for the same task—a cherished grape instead of a bit of cucumber—they became likely to refuse participation, the study showed.
