scientists are smashing the brains of invasive iguanas


researchers are taking a controversial approach as they try to rid florida of invasive iguanas overtaking residents’ yards by bashing in their brains.a team from the university of florida is using a captive bolt gun that sends a bolt into the brain, similar to what’s used in the livestock industry. they’re also smashing the creatures’ heads against solid objects to cause blunt force trauma. they’ve killed 249 so far.uf wildlife biologist jenny ketterlin told the sun sentinel it’s the most humane way to kill them.“most of what we’re doing is blunt force trauma,” ketterlin told the paper. “hitting their head very hard against a solid object.”the theory goes that by destroying their brains is the most painless option, hence humane.their work is part of a research project...

invasive species are a growing global threat


the aliens among usleslie anthonyyale univ. press, $30remote bouvet island, a tiny, glacier-smothered landmass in the south atlantic rimmed by 500-meter-tall cliffs, has a notable distinction: it’s the only known spot on earth, scientists say, that has zero invasive species. every other place, and every person, on the planet is at least indirectly affected by one or more species that has been transported — either intentionally or inadvertently — to new lands from the ecosystems in which the species evolved.in the aliens among us, biologist and science journalist leslie anthony chronicles the detrimental effects of invasive species, as well as how these organisms spread and how they can be fought. in the united states, such interlopers — everything from zebra mussels in the great la...






scientists identify brain’s ‘anxiety cells’ — and how to control them


scientists have discovered specialized brains cells that appear to influence anxiety levels.the research, published in science journal neuron, found that scientists could control the activity of the brains cells of anxious mice.the brain cells, which were the source of the anxious behavior could be turned on and off.it’s hoped the breakthrough could lead to more effective treatment for the approximately one-fifth of us adults who experience anxiety.the team of researchers discovered the cells in the hippocampus, a part of the brain that’s linked to anxiety as well as navigation and memory.the cells in the hippocampus communicate with another region of the brain, the hypothalamus, which tell the mice when to avoid a potentially dangerous situation.the study involved studying mice in a m...






40 more ‘intelligence’ genes found


smarty-pants have 40 new reasons to thank their parents for their powerful brains. by sifting through the genetics of nearly 80,000 people, researchers have uncovered 40 genes that may make certain people smarter. that brings the total number of suspected “intelligence genes” to 52.combined, these genetic attributes explain only a very small amount of overall smarts, or lack thereof, researchers write online may 22 in nature genetics. but studying these genes, many of which play roles in brain cell development, may ultimately help scientists understand how intelligence is built into brains.historically, intelligence research has been mired in controversy, says neuroscientist richard haier of the university of california, irvine. scientists disagreed on whether intelligence could actual...






in a tally of nerve cells in the outer wrinkles of the brain, a dog wins


if more nerve cells mean more smarts, then dogs beat cats, paws down, a new study on carnivores shows. that harsh reality may shock some friends of felines, but scientists say the real surprises are inside the brains of less popular carnivores. raccoon brains are packed with nerve cells, for instance, while brown bear brains are sorely lacking.by comparing the numbers of nerve cells, or neurons, among eight species of carnivores (ferret, banded mongoose, raccoon, cat, dog, hyena, lion and brown bear), researchers now have a better understanding of how different-sized brains are built. this neural accounting, described in an upcoming frontiers in neuroanatomy paper, may ultimately help reveal how brain features relate to intelligence.for now, the multispecies tally raises more questions tha






til that elephants think that humans are cute like puppies (18 photos) : thechiv


scientists have found that elephants have brains that are similarly wired as human brains are, and they have a higher emotional intelligence than nearly every other creature on earth. due to their large and highly complex hippocampus, they can express and feel a wide range of emotion, and process a lot of emotional information.they’re also capable of understanding our language, our body language, and can even use tools and mimic our voices.






researchers discover blood vessels in lab-grown mini-brains


after some three days of culturing the mini-brains, the scientists discovered that a majority of the samples had developed on their own. after inspecting the "tangles of spaghetti," the researchers found that said tangles had grown on their own and were comprised of the cells and proteins found in blood vessels, according to eurekalert.naturally, there wasn't any blood flowing through them but senior author of the study diane hoffman-kim said she has a few ideas for how to make that happen. one would involve hooking a special device to provide circulation, called a microfluidic apparatus, to the mini-brains.should this all pan out, it could give scientists a better idea of how the brain and vascular system work and even spare the lives of a few test animals in the process. there are probab






from day one, a frog’s developing brain is calling the shots


frog brains get busy long before they’re fully formed. just a day after fertilization, embryonic brains begin sending signals to far-off places in the body, helping oversee the layout of complex patterns of muscles and nerve fibers. and when the brain is missing, bodily chaos ensues, researchers report online september 25 in nature communications.the results, from brainless embryos and tadpoles, broaden scientists’ understanding of the types of signals involved in making sure bodies develop correctly, says developmental biologist catherine mccusker of the university of massachusetts boston. scientists are familiar with short-range signals among nearby cells that help pattern bodies. but because these newly described missives travel all the way from the brain to the far reaches of the b...






protein helps old blood age the brains of young mice


old blood can prematurely age the brains of young mice, and scientists may now be closer to understanding how. a protein located in the cells that form a barrier between the brain and blood could be partly to blame, experiments on mice suggest.  if something similar happens in humans, scientists say, methods for countering the protein may hold promise for treating age-related brain decline.the preliminary study, published online january 3 at biorxiv.org, focused on a form of the protein known as vcam1, which interacts with immune cells in response to inflammation. as mice and humans age, levels of that protein circulating in the blood rise, alzheimer researcher tony wyss-coray at stanford university and colleagues found.  after injecting young mice behind an eye with plasma from old mice..






iguanas falling from trees in frigid florida


if you are "suffering" through the sub-40-degree temperatures in florida, consider yourself lucky you are not an iguana. when it drops below 50, the cold-blooded creatures get sluggish, and if it gets any lower than that, they freeze up, according to experts. with the unusually frigid conditions down south, they have been plummeting from trees. "it's too cold for them to move," said kristen sommers of the florida fish and wildlife conservation commission. frank cerabino, a columnist for the palm beach post, tweeted a photograph of an iguana lying belly-up next to his swimming pool. tv station wpec posted images of an iguana on its back on a road in palm county. curious residents who find paralyzed iguanas should be careful, or they might get a nasty surprise i...

your child mightn't need a fidget spinner, they need to experience boredom


the brain has the magical ability to rewire itself. we live in the world that offers our brains instant gratification, which works just like a drug. the more instant gratification we offer our brains, the more our brains crave it.  with the best of intentions, we have rewired the brains of this entire generation of children to expect instant gratification, by offering them ipads, videogames, and depriving their brains of opportunities for boredom, responsibilities, and limits. children come to school emotionally unavailable to learn. it's important to teach children that "boredom" is a normal state of human emotions.  photo: stocksytheir brains are unable to function under lower levels of stimulation, and expect special effects at all times. unfortunately, real life can't offer t...






studying brains of spellers can help scientists improve tests


are great spellers made or born? and how can we tell? and why does it matter? scientists have long given second-class treatment to the study of the relationship between spelling and the brain, preferring instead to focus on reading in efforts to better understand literacy and communication. but now, some researchers are working hard to probe the question: what makes a human being really good at spelling? and just as pressing: what makes a person really bad at spelling? at their core, both questions relate to communication and language. thus, scientists who are studying ways to improve literacy are concerned with the topic.5-year-old becomes youngest-ever national spelling bee contestant but anyone looking for easy answers will be d-i-s-a-p-p-o-i-n-t-e-d.brenda rapp is ...






scientists invent ‘pen’ that can detect cancer cells in seconds

neuroscience - are male and female brains physically different from birth?


what about physical differences from birth? are there differences in size, regions, chemical composition, etc. from birth?one significant, inherent difference between male and female human brains [from birth & throughout the rest of life] is that male brains are 10-20% larger than female brains. according to a study performed by the united medical & dental college in karachi, pakistan:in this article it is reviewed that how does the brain of a male look and function differently from a female's brain, and what accounts for these differences? ..male brains are about 10% larger than female brains and weigh 11-12% more than that of a woman. men's heads are also about 2% bigger than women's. this is due to the larger physical stature of men. male's larger muscle mass and larger body size re...

why scientists are picking rats’ brains, technology news, ettech


rats are a nuisance to most people, but neuroscientists at the national centre for biological sciences (ncbs) in bengaluru buy rats with specific dispositions and look after them with great care.some of the rats are healthy, others have a disorder similar to autism in human beings. you can’t put electrodes into a living human brain, but scientists can do that to a rat. by looking into a rat’s brain, scientists hope to understand something about a living human brain. especially, how it goes haywire.neurological disorders affect a large proportion of indians. epidemiology studies have put its prevalence at about 2.3% of the country’s population. children are also vulnerable to neurological diseases. for example, autism affects roughly one child in 500 in india, and its rate of incidenc...






human brains rounded into shape over 200,000 years or more


big brains outpaced well-rounded brains in human evolution.around the time of the origins of our species 300,000 years ago, the brains of homo sapiens had about the same relatively large size as they do today, new research suggests. but rounder noggins rising well above the forehead — considered a hallmark of human anatomy — didn’t appear until between about 100,000 and 35,000 years ago, say physical anthropologist simon neubauer and his colleagues.using ct scans of ancient and modern human skulls, the researchers created digital brain reconstructions, based on the shape of the inner surface of each skull’s braincase. human brains gradually evolved from a relatively flatter and elongated shape — more like that of neandertals’ — to a globe shape thanks to a series of genetic t...
