Pheromone from mother's milk may rapidly promote learning in newborn mammals

...romone may act as a kind of organizing signal that boosts the brain's ability to associate new odors with milk availability. This would in turn facilitate an essential skill: the ability of newborn pups to rapidly hone their suckling instincts during the first days of life. ...

New approach could lower antibiotic requirements by 50 times

...y to channel through bacterial cell membranes that boosts antibiotic effectiveness. 'Pseudomonas bacteria for example are particularly multi-resistant to antibiotics because they have efflux pump mechanisms that enable them to throw out antibiotics. A pore in the cell wall would obviously cancel the efflux ...

Scientists re-grow dental enamel from cultured cells

... known as the 3T3-J2 cell line). This crucial step boosts the number of dental epithelial cells available for enamel production. In the study being reported today, the researchers seeded the cultured dental epithelial cells onto collagen sponge scaffolds, along with cells from the middle of the tooth (denta...

How appetite-stimulating brain cells work overtime during fasting

...d increases in an "uncoupling" protein (UCP2) that boosts the number of power-generating mitochondria in neurons that drive hunger. The increase in mitochondria, in turn, allows the brain's hunger center to remain active when periods of food scarcity result in a "negative energy balance," said Sabrina Diano...

Catching cancer's spread by watching hemoglobin

...be detected to build up an image. One "pump" laser boosts (excites) hemoglobin molecules to a higher energy state. The other "probe" laser monitors the hemoglobin after the excitation. Sometimes the pump laser is off and there is no two-photon absorption. By subtracting the signal from the "off" state from ...

Newly discovered antibody may be body's natural defense against Alzheimer's

...zheimer's. Still, this discovery substantially boosts our understanding of Alzheimer's and other neurodegenerative illnesses, the experts say....
