Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

... said. Several evidence-based therapies exist, and unlike medication, none of them are suspect in the least for causing adverse effects to baby. Given prenatally, psychological interventions could instill a whole host of benefits that may carry-over to the child, OConnor said. Still, more clinical rese...

Genomic Analysis Uncovers New Targets for HIV Vaccine

...V-1. Since HIV-1 appears unable to shut off HLA-C, unlike A and B, HLA-C may represent an Achilles heel of HIV, according to Goldstein, who said that a vaccine could be designed to elicit an HLA-C mediated response which HIV-1 might be unable to defuse. "This study was the first time a genome-wide approach...

Bigger horns equal better genes

...avy, and the ibex carries them for their lifetime, unlike antlers which are shed every year. They also cause the ibex to lose heat in winter, because their core is heavily vascularized." Found exclusively in the Alps mountain range in Europe, alpine ibex were hunted almost to extinction about a century ...

U-M researchers discover gene switched off in cancer can be turned on

...ncers. They typically have few toxic side effects, unlike traditional chemotherapy, making them more tolerab... can be treated for long periods of time, which is unlike older and more traditional chemotherapy agents. Even if these new targeted therapies don’t cure the ...

Exploring the dark matter of the genome

...) between the coding sections of the gene (exons); unlike the introns in euchromatic genes, these long gaps consisted almost entirely of repeating sequences derived from disabled transposons. The evidence suggests that heterochromatic genes are regulated differently from euchromatic ones. Besides protei...

Surprising origin of cell's internal highways

...olgi also makes microtubules," Kaverina said. "And unlike centrosomal microtubules, which are radial and symmetric, these microtubules are directional." They found that microtubules originating at the Golgi are directed toward the cell "front," or the leading edge, of motile cells. Since such an orientat...

New bacteria test could improve quality of fruit and vegetable juice

...tifies the organism quickly ?in a matter of hours, unlike traditional culturing methods, which are time consuming and require five to seven days to process. Lin said that testing time is critical for juice processing companies, which monitor for the bacteria during the processing and final product stage. He...

The quest for an effective HIV vaccine presents new possibilities, challenges

...nitely. Other viruses also replicate robustly but, unlike HIV, most do not establish a permanent reservoir of infected cells in the body. The window of opportunity to prevent long-term HIV infection may close permanently once a pool of latently infected cells is in place, Drs. Johnston and Fauci note. Neutr...

Selectivity is ultimate aphrodisiac

...ontact one another. "People who like everyone, unlike in a friendship context where they generally are liked in return, may exude desperation in a romantic context," Finkel said. "It suggests to us that romantic desire comes in two distinct flavors: selective and unselective," Eastwick added. "If y...

The penalty of having a sister -- why sibling sex matters for male saiga antelopes

...rs from mixed litters are generally infertile. But unlike dairy cows, in cases of saiga mixed-sex twins, the male foetus appears to be worse off, not the female. Aline adds that the effect of size on male saigas later in life cannot be underestimated: "Even a relatively small decrease in birth weight is...

Drug-resistant bacterial infections serious complication after corrective eye surgery

...d to be resistant only to beta-lactam antibiotics, unlike the hospital strains, which usually demonstrate multiple drug resistance. Community-acquired MRSA is becoming a significant problem, with the prevalence of MRSA among community isolates expected to reach as high as 25% in the next decade. The auth...

Newborn brains grow vision and movement regions first

...events that happen after birth," Gilmore said. "So unlike the gender differences, the asymmetry differences arise after a baby is born." For the study, 74 newborns at the University of North Carolina Hospitals were given high-resolution magnetic resonance imaging (MRI) scans in the first few weeks after b...

Wheat can fatally starve insect predators

... lectin that don't cost the plant much to produce, unlike producing poisons and stronger walls. Those inducible defenses use a lot of a plant's energy that could be used toward growth and reproduction." The scientists currently are looking for regulatory regions in Hessian fly-susceptible wheat genes tha...

Darwin's famous finches and Venter's marine microbes

... the HMS Challenger in the nineteenth century. But unlike those pioneering expeditions, the Sorcerer II team led by J. Craig Venter and a globe-spanning network of collaborators are after tiny microbes, classifying the species they encounter not by their appearance but by their unique genetic code. The ...

Surgeons develop simpler way to cure atrial fibrillation

... clotting associated with atrial fibrillation, but unlike the Cox-maze procedure, the drugs do not cure the disorder. Damiano says their most recent study of Cox-maze IV is unique because the surgeons carefully matched the age, sex and cardiac conditions of a group of patients who underwent Cox-maze III ...

New biofuels process promises to meet all US transportation needs

...ources, such as solar, wind or nuclear power. And, unlike conventional methods of producing liquid fuels from plant matter and coal, H2CAR would not emit carbon dioxide into the atmosphere. "The goal is to accomplish the complete transformation of every carbon atom in the feedstock to liquid fuel by supp...

Paleontologists discover new mammal from Mesozoic Era

...thoracic ("chest") and lumbar ("waist") vertebrae, unlike most living and extinct terrestrial mammals that commonly have 19 or 20 thoracic and lumbar vertebrae. The extra vertebrae give Yanoconodon a more elongated body form, in contrast to its relatively shorter and very primitive limb and foot structures....

Bumblebee house warming -- it takes a village

...ebee common in the Pacific Northwest. Bumblebees, unlike most insects, are warm-blooded. They can heat their bodies, and can remain active at cooler temperatures than many other insects. To achieve optimum conditions for their young, bumblebees rely on nest thermoregulation, actively raising or lowering ...

Walking molecule now carries packages

...quires roughly three times the energy. This is not unlike a human being carrying heavy loads in one or both hands." Bartels explained that using machines at the scale of single molecules will ultimate be the most efficient way to build objects or to deliver material. "It resembles the way nature does it:...

Viral protein is an effective preventative against infection

...rial cell as well as from the inside. In addition, unlike antibiotics, which kill many of the body’s beneficial bacteria along with the disease-causing ones they target, lysins are highly specific. Each lysin will only kill a specific type of bacteria, leaving the body’s normal flora untouched. "We knew ...
