New designer lipid-like peptide with lipid nanostructures for drug delivery systems

... Zhang of MIT, a co-author said, “people have been curious about if these similar molecules can interact. This study provided the first answer”. “Since these lipid-like peptides can be designed, just like to design an elegant watch, an art object, a music instrument, a ski, or a pair of sunglasses, we have...

Out-of-body experiences may be caused by arousal system disturbances in brain

...xperiences in the near death experience subject is curious and unexplained," Nelson said. "However, persons with near death experiences appear to have an arousal system predisposed to both REM intrusion and out-of-body experiences." ...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...s the focus of most vaccines, scientists have been curious to measure how a vaccine without neuraminidase performs. ...

Renegade RNA -- Clues to cancer and normal growth

... aspects of their behavior in cells. They also are curious to figure out what miR-29b is doing in the nucleus. Because microRNAs have been implicated in cancer as well as normal development, Mendell hopes that further study of miR-29b will reveal other, hidden functions of microRNAs. ...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...nventing the wheel.? Pandey and his team now are curious about other chemical modifications of proteins, which are the “business-end?products of our genes. “There is evidence of other, more fragile modifications that until now no one has been able to get a handle on because they’re way too hard to work wi...

Fishy cooperation

...hat groupers actively recruit moray eels through a curious head shake made close to the moray eel's head to which the eel responds by leaving its crevice and joining the grouper. Groupers showed such recruitment more often when hungry. The observed role division comes "naturally" to two predators with dif...

Queen bee promiscuity boosts hive health

...he Proceedings of the Royal Society of London, the curious promiscuity of queen honeybees has long perplexed apiculturists, especially since seeking out multiple mates takes more time and energy and puts the queens at greater peril for predator attacks. "Even though just one male provides all the sperm tha...

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

...d Dec. 21 in the science journal Nature. He became curious when he observed that a mole he was studying blew a lot of bubbles while swimming. "This came as a total surprise because the common wisdom is that mammals can't smell underwater,' said Catania, who earlier this year won a $500,000 "genius grant" ...

Stomach receptor for H. pylori discovered

... microbial pathogens. Peek and his colleagues were curious as to whether DAF was also involved in H. pylori adherence. To do this, the researchers measured the number of H. pylori that bound to cells that either expressed or did not express DAF. They found that the bacteria do indeed adhere to cells with DAF...

Alaska seal pup diet may hold key to decline of population

...ets as the longitudinal research continues. "We're curious to find if it will take longer for the low fat diet animals to reach sexual maturation," Polasek said. Human females who consume an extremely low fat diet reach sexual maturity later than those who consume a high fat diet, she noted. In addition, th...

Possible brain hormone may unlock mystery of hibernation

...' brains cuts hibernation short. "One of the most curious biological phenomena in mammals is their ability to hibernate circannually, which allows them to survive unusually low body temperatures at or near freezing," said study author Takashi Ohtsu of Kanagawa Academy of Science and Technology in Japan. Sci...

Molecular mechanism may explain how fevers spark seizures

...r convulsions in children," she said. "I have been curious about this mystery for years." Kang came to Vanderbilt to work with Macdonald, internationally renowned for his research on epilepsy and GABA-A receptors, proteins on the surfaces of nerve cells that normally quiet the brain's excited chatter. GA...

Lizard 'third eye' sheds light on evolution of color vision

... rods and cones, came about. As he says, he's most curious about how the same function can be achieved in different ways in different animals. ...

Ancient DNA provides clues to the evolution of social behavior

... low only solves part of the mystery. ''The really curious thing is how the species managed to persist for around 3,000 years with almost no genetic variation,'' Hadly says. ''Genetic variation is the toolkit for dealing with whatever the environment has to throw at you. If you have only a couple of tools, y...

'Banana-jawed' fossil mammal linked to rare sound-producing skill

... model their jaws so we could hear the sound these curious creatures actually made." ...

A resetting signal keeps circadian rhythm on track in Drosophila fruit flies

...nisms are quite conserved with mammals." "We were curious about how these brain cells stay synchronized, so we controlled the way time was ticking in individual clocks: we made the morning cells run faster and the evening cells relatively slower, and the other way around," explained researcher Dan Stoleru. ...

Seaweed yields new compounds with pharmaceutical potential

...riations of them. "These molecular structures are curious in the way carbon atoms are attached," Kubanek said. "It's very unusual. They represent a new category of organic molecules. It's exciting as a biochemist to observe that living organisms have evolved the ability to synthesize such unique and exotic ...

Malfunctioning bone marrow cells sabotage nerve cells in diabetes

...tal or beneficial," said Chan. In pursuit of this curious phenomenon, Drs. Tomoya Terashima and Hideto Kojima from BCM and Dr. Mineko Fujimiya of Shiga University of Medical Science in Shiga, Japan, in collaboration with Chan, performed numerous experiments in diabetic rats and mice. Their work defined the ...

Woods Hole Research Center plans controlled burn in Amazon rainforest

... fuel will be very dry. Center scientists are also curious to see how those trees that have resprouted from their roots will fare in this second fire, as their profusions of dense, green, living branches are very close to the ground and may be damaged if too close to the flames. If their standing dead trunks...

Researchers discover mechanism for multiplying adult stem cells

...nisch's lab, was experimenting with the Oct4 gene, curious to see what happens in laboratory mice when the gene is reactivated in adult tissue where it has long been dormant. Hochedlinger found that when he switched the gene on, the mice immediately formed tumors in the gut and in the skin where the gene was...
