Tracking sperm whales and jumbo squid

...face; and only by inference is it that any one can tell of what, precisely, that food consists." The sperm whale remains a challenging research subject for scientists today, Davis noted. "Adult sperm whales can stay underwater for more than an hour, but nobody knows exactly what they’re doing down ther...

Imaging pinpoints brain regions that 'see the future'

...rly what happened last month and they can't really tell you much of anything about what they envision happening next week. This is also the case with suicidally depressed people. So, there's this theory that it all goes hand-in-hand, but nobody has looked closely enough to explain exactly how or why this ...

Action video games sharpen vision 20 percent

... the test, but the Unreal Tournament players could tell which way the "T" was pointing much more easily than they had just a month earlier. "When people play action games, they're changing the brain's pathway responsible for visual processing," says Bavelier. "These games push the human visual system to...

Discovery of new cave millipedes casts light on Arizona cave ecology

...vive these dark and resource-poor environments can tell us a lot about what makes them so successful as a group." While conducting ecological inventories of 30 caves on the Colorado Plateau of northern Arizona, research by Wynne and Voyles has resulted in the discovery of at least 10 new species, inclu...

Man's best friend lends insight into human evolution

...dden food, dogs often grasp what you are trying to tell them. Puppies even do it without prior training, indicating that it is an innate ability, not simply one they acquire through contact with their owners. What accounts for this piece of convergent evolution between humans and domestic dogs is noth...

Leukemia drug turns mini-molecules up, cancer genes down

...gene. "The findings are important because they tell us that some miRNAs switch off genes that promote cancer," says first author Ramiro Garzon, a hematologist and oncologist at Ohio State's James Cancer Hospital and Solove Research Institute. Acute promyelocytic leukemia occurs when cells that giv...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...it was produced," Thompson writes, "it has much to tell us about the culture that created it." (2pAAb1) REHABILITATING THE WORLD'S WORST SOUNDS Something that is very 21st century is the ability to gradually morph, or transform sounds from one to another. A variation of morphing is to transfer t...

Automatic identification of protein's critical features from the structure

...t express who we are, but is it really possible to tell the essence of an individual from its form? The answer to that question seems to be related to fashion and glamour, yet a group of scientists from the Universidad Nacional Autonoma de Mexico and the Buck Institute in the USA, were able to address it,...

Master regulatory gene of epithelial stem cells identified

...netic programs controlled by these regulators will tell us much about how stem cells function and how they go awry in cancer." ...

Lessons from the orangutans: Upright walking may have begun in the trees

...re right, it means you can't rely on bipedalism to tell whether you're looking at a human or other ape ancestor. It's been getting more and more difficult for us to say what's a human and what's an ape, and our work makes that much more the case." Crompton and his colleagues, Susannah Thorpe and Roger ...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...kills competing bacteria." Genome sequences can tell us a lot about the biology of the organism, but research into clostridia has been hampered by the lack of a good genetic system. Professor Nigel Minton, Professor of Applied Molecular Microbiology at The University of Nottingham, has developed new me...

Human genetic 'deserts' are teeming with significant life

...ts are in fact teeming with life, a scientist will tell the annual conference of the European Society of Human Genetics today (Tuesday 19 June). Most known human genes in the genome map are still incompletely annotated, says Professor Alexandre Reymond, from the Centre for Integrative Genomics, Universit...

Runners -- Let thirst be your guide

...y sweat while exercising, but this simple test can tell you approximately how much fluid losses you are generating from sweat,” he says. “There is no need to drink significantly more than that, because sweat represents the major source of fluid loss during exercise.” A healthy person needs to be dehydr...

Study shows lizard moms dress their children for success

...re genes for these traits, and it's really hard to tell the maternal effects apart from the effects of the genes," he said. Lancaster began by treating side-blotched lizard eggs with an array of different hormones. That revealed a striking influence of estradiol on back patterns. She also tested eggs f...

Agent slows aging in mice

...s out to be good for mice, it won’t be possible to tell without careful studies of humans whether NDGA is beneficial, useless, or harmful to people. Occasionally, something that is harmless in mice turns out to be highly toxic for people,” Miller cautions, adding that the Food and Drug Administration doe...
