After a time-shift, mixed signals from the circadian clock

...er, that different components of the clock tend to adapt to a shifted light schedule at two different speed...ence, in complex ways, how the two groups of cells adapt to a shifted light schedule. The authors conclude that the phases of activity in the ventral and do...

Advancements In Genomics Foster Deep Sea Discoveries

...tes the expression of genes that help the cells to adapt to the increased pressure,?said Bartlett. The scientists found other tantalizing discoveries in Photobacterium profundum, including a novel fermentative process, adaptations to electron, proton and nutrient transport across membranes and a large numb...

Same-Sex Mating Discovered in a Toxic Fungus

...ffspring with different gene combinations that can adapt more rapidly to new environments," said HHMI investigator Joseph Heitman, M.D., Ph.D., of Duke, senior author of the study. "The findings suggest for the first time that the fungus has developed a novel type of sexual cycle, allowing sexual reproduc...

Reservoirs may accelerate the spread of invasive aquatic species, researchers say

...t helps invaders from saline and brackish habitats adapt to fresh water. Several invasive species are suspected to have benefited from the use of reservoirs as avenues, including Daphnia lumholtzi, a water flea from the Old World tropics, and the copepod Eurytemora affinis. Some evidence indicates that th...

Gray wolves maintain the food chain in winter

...et for scavengers, extending the time they need to adapt to a changing environment. Thanks to a rebounding wolf population, field researchers can measure the magnitude of this predicted buffer effect. The models described here can guide their efforts and help species adjust to major environmental shifts li...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

Same mutation aided evolution in many fish species, Stanford study finds

...y are an ideal model for understanding how animals adapt to their unique environments. The recent work car...articular genes are always reused when the animals adapt to new conditions, or if evolution has other tricks up its sleeve to push organisms towards an optim...

Highly adaptable genome in gut bacterium key to intestinal health

...th, it is important to understand how gut microbes adapt to the dynamic environment of the gut and ensure the functional stability of the intestinal bioreactor, the researchers say. In addition, variations in the composition of gut microbial communities among different people may be an important factor tha...

Antibiotic Resistant Bacterium Uses Sonar-like Strategy to “See?Enemies or Prey

...ccordingly. We maybe able to learn from nature and adapt a similar strategy to help theaging population cope with loss of vision,?says Gilmore.“Secondly, this discovery will help us to develop new ways to treatinfections that are resistant to antibiotics, making them less severe.Based on an understanding o...
