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

... anxiety, later on down the road, OConnor said. It remains to be seen if the sleep problems we witnessed may play an active, causal role in priming the path for these childrens emotional and cognitive problems in later life, or if both conditions merely fall out of the same stressful pregnancies. Related...

Soils offer new hope as carbon sink

...and the environment is that the carbon in agrichar remains locked up in the soil for many years longer than, for example, carbon applied as compost, mulch or crop residue. "We broadly categorise carbon in the soil as being labile (liable to change quickly) or stable – depending on how quickly they break d...

A new plant-bacterial symbiotic mechanism promising for crop applications

...of the nature of the signal molecule itself, which remains to be fully determined, brings a glimpse of future agricultural applications. Many plants live in symbiosis with bacteria, but the mechanisms are known for only a small number of these interactions. The demonstration of alternative pathways capab...

Undergraduate research shows leaderless honeybee organizing

...rs studying social behavior, a great mystery still remains regarding how bee societies effectively direct and coordinate complex operations without a central controlling intelligence. Pierce’s finding is part of an ongoing research effort in Schneider’s lab aimed at understanding the mechanisms of leaderless...

Small, self-controlled planes combine plant pathology and engineering

...’s most devastating plant and animal pathogens and remains largely a mystery to scientists who do not have a firm understanding of its ability to travel long distances in the atmosphere. By placing antibiotics in the sampling collection plates, researchers can ensure that only Fusarium will grow on the plate...

...ence in a novel solvent.” The chemistry at work remains largely a mystery, Zhang said, but he suspects that metal chloride catalysts work during an atom-swapping phase that sugar molecules go through called mutarotation, in which an H (hydrogen) and OH (hydroxyl group) trade places. The hydrogen-hydrox...

UI anthropologist, colleagues discover remains of earliest giant panda

...es (PNAS). Previous discoveries of teeth and other remains made between 1985 and 2002 had failed to establish the animal's size. Ciochon says that the ancient panda (formally known as Ailuropoda microta, or "pygmy giant panda") was probably about three feet in length, compared to the modern giant panda, w...

Prey not hard-wired to fear predators

Notes on the Study The study compared the behaviors of four species of prey animals in three different prey situations: ...

A first -- Hebrew University scientist observes brain cell development in 'real time'

...tructural and functional complexity of nerve cells remains one of the biggest mysteries of neuroscience, and we now have a model to study this complexity directly." The results of Dr. Mizrahi’s groundbreaking work appeared in the online edition of Nature Neuroscience. Using special microscopic imaging...

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

...st with a microbial sledgehammer. It then eats the remains and lays low until the next host comes along." The genome sequence is peppered with genes that produce enzymes to digest proteins and other animal material in the soil. Also found, uniquely in this species, is a range of genes that allow it to att...

Ants show us how to make super-highways

...eveloping young at maximum speed. The raid always remains connected to the nest by a trail of forager traffic, along which prey-laden foragers run back to run back to the nest. This trail can be extremely uneven and full of ‘pot holes’ as it passes over leaves and branches on the forest floor. The study,...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

...ng normal muscle function," said Berdeaux. "Now it remains to be seen how this pathway works in muscle under different conditions, such as during exercise, as well as what part it plays in maintaining cell survival in other tissue types and in other species." Indeed, all mammals have SIK1, not just mice,...

Scripps research team sheds light on long-sought cold sensation gene

...ts as a gate," says Dhaka, "At warm temperature it remains closed, but opens when exposed to cool temperature." The TRPM8-deficient mice did not lose their ability to feel pain in response to extreme cold, as evidenced by responses similar to wild type mice when exposed to -1° C cold plates. This suggest...

'Insulator' helps silence genes in dormant herpes virus

...-1. After the initial infection, the virus usually remains in the body, hiding out in nearby nerve cells where the victim's immune defenses cannot reach it, causing no symptoms at all. In order to escape detection by the body's immune system, the latent virus works to silence genes that would cause it to re...

Keeping the immune system from starting a 'food fight'

... that the realization of such a treatment strategy remains uncertain and would require years of continued investigation. Cells and organisms must strike an appropriate balance between nutrient sufficiency and surplus, the researchers explained. While adequate amounts of nutrients must be obtained to ensur...

Corals -- More complex than you?

... Who has the best formula for long-term survival remains unclear. Today’s corals first appeared 240 million years ago. So far humans have barely survived for 2 per cent of the time that corals have endured. Despite all they mean to Australia and have to offer science and medicine, our corals remain gen...

New technique will produce a better chromosome map

..., and yet its relationship to chromosome structure remains unclear. "Since we want to know what genes are involved in the development of different structures in living systems, this is the first structure to look at," Novikov said. "This is the starting point: the appearance of the genes themselves." ...
