NASA-funded robotic sub finds bottom of world's deepest sinkhole

...hat it will have applications in environments with similarly sparse features, like rivers or mines. Though initially operated on a tether, DEPTHX eventually operated autonomously, without a tether or human guidance, for eight hours at a time. "The fact that we never lost it, never required a rescue mission,...

Premature births may be linked to seasonal levels of pesticides and nitrates in surface water

...rrent and seasonal manner. Pesticides and nitrates similarly vary seasonally in surface water throughout the U.S. Nitrates and pesticides can disrupt endocrine hormones and nitric oxide pathways in the developing fetus," he said. "I believe this work may lay the foundation for some of the most important ba...

Parasites' impact goes beyond host to affect ecosystem

...l), uninfected snails, and infected snails -- they similarly saw less reduction of ephemeral algae by infected snails. But when researchers isolated ephemeral, or edible, algae, "we saw dramatic change," says Byers. Edible algae account for a small proportion of macroalgae on rocky shorelines ?just about se...

Fused nasal bones helped tyrannosaurids dismember prey

... and a half times as long. T. rex's neck power was similarly staggering. For instance, in a split second, a T. rex could toss its head at a 45 degree angle and throw a 50kg person five metres in the air. And that's with conservative estimates of the creature's muscle force, says Snively. "We kept the muscle ...

Whiteflies and plant viruses can help each other to speed up biological invasion

...cs. In contrast, the indigenous whitefly performed similarly on healthy and virus-infected plants. "This is the first study that shows an invasive insect has such a mutualistic relationship with the viruses it transmits, whereas its indigenous counterpart does not," said Professor Shu-Sheng Liu, correspond...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...rarely see their sixth birthday. Sandhoff mice are similarly affected. Tay-Sachs is predominant to Ashkenazi Jewish populations, while Sandhoff, a severe form of Tay-Sachs, is not limited to any ethnic group. Both diseases are marked with deficient Hex enzyme functioning and are among a known group of about 50...

Hofmeyr skull supports the 'Out of Africa' theory

...ssil skull from the southernmost tip of Africa and similarly ancient skulls from Europe is in agreement with the genetics-based "Out of Africa" theory, which predicts that humans like those that inhabited Eurasia in the Upper Paleolithic should be found in sub-Saharan Africa around 36,000 years ago. The skull ...

Bats prey on nocturnally migrating songbirds

...ich exist elsewhere in the world. Are some of them similarly stalking unwary songbirds during their massive nocturnal passes? The foraging habits of these rare bats still remain quite mysterious, like in the case of giant noctules until recently. Stable isotopes could be a promising tool for unravelling their ...

Researchers first to map gene that regulates adult stem cell growth

... such as the liver, skin, pancreas or brain may be similarly affected by Latexin. This could open up new therapeutic strategies such as using stem cells for the treatment of other diseases and conditions such as liver disease, diabetes and central nervous system damage as a result of trauma or stroke. The re...

Biologically inspired sensors can augment sonar, vision system in submarines

...ateral line, a submarine or underwater robot could similarly detect and track moving underwater targets, and avoid collisions with moving or stationary objects. The artificial lateral line consists of an integrated linear array of micro fabricated flow sensors, with the sizes of individual sensors and spacin...

Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows

...rst example, he allowed the animals to explore two similarly sized, yet obviously different, objects for 15 minutes. Twenty-four hours later he exposed the same animals to one of the previously seen objects and a third, never-before-seen object. Although wild-type mice spent more time investigating the new obj...

New insights into autoimmunity and depression

...LE could help determine whether these pathways are similarly affected in humans. "The relevance of the results to the involvement of the central nervous system in SLE is another intriguing aspect of the present study," notes its leading author, Yehuda Shoenfeld, M.D., while emphasizing the need for further ...

Two nerve cells in direct contact

...ation flow fields." Whether nature has constructed similarly simple mechanisms in mammals is still unclear - the circuitry of the nerve cells in the relevant areas in the cerebral cortex has not yet been sufficiently explained to allow experiments of this nature to be carried out. And it is rather doubtful whe...

Researchers identify new weapon to fight deadly bacterial sepsis

...h) has demonstrated that blocking aldose reductase similarly can dramatically reduce the inflammation-driven processes of colorectal cancer and complications of diabetes. "There are so many inflammatory signaling processes that depend on this enzyme, and so it made sense to look into with regard to sepsis, ...

Altered perception of reward in human cocaine addiction

...y to control behavior. The ERP results showed a similarly graded brain response to monetary reward in healthy control subjects, but not in cocaine-addicted individuals. "The dysfunctional interplay between reward processing and control of behavior observed in these studies could help to explain the chron...

Fighting like a girl or boy determined by gene in fruit flies

...id, "and flies in many respects behave and respond similarly to humans." The findings provide a welcome guidepost to help enable future research to track down the underlying neural circuitry, said Bruce Baker, a biology professor at Stanford who first linked the fruitless gene to male-specific courtship beh...

Mirrors in the mind: New studies elucidate how the brain reflects onto itself the actions of others

...ng that a particular area of the brain can respond similarly to execution of an action and its representation in different types of sensory cues. Intriguingly, the researchers also found that of the subjects taking part in the experiment, those that scored higher on tests for empathy activated the system more...

Buildup of damaged DNA in cells drives aging

...er chemotherapy agent, the growth hormone axis was similarly suppressed. In other words, DNA damage somehow triggered hormonal changes that halted growth, while also boosting maintenance and repair. Because growth hormone levels go down as we get older, contributing to loss of muscle mass and bone density, ...

Recurrence of a flu pandemic similar to infamous 1918 flu could kill 62 million

...populations, the research team estimated that if a similarly virulent strain of flu virus were to strike today, about 62 million people worldwide would die. This could represent a devastating impact on global mortality, more than doubling deaths from all causes in a single year. However, only four percent o...

Dust to gust

... into the valley focus on this funnel-like opening similarly to the way light is focused by an optical lens, creating a large wind tunnel of sorts. As a result, gusts of surface wind that are accelerated and focused in the tunnel lift the dust from the ground and blow it toward the ocean, allowing the Bodélé v...
