Study demonstrates direct link between juvenile compensatory growth and reproduction

University of California, Riverside biologists working on guppies - small freshwater fish that have been the subject of long-term studies - report that rapid growth responses to increased food availability after a period of growth restriction early in life have repercussions in adulthood.

Researchers identify a stress hormone in sea lamprey

Michigan State University researchers are the first to identify a stress hormone in the sea lamprey, using the 500 million-year-old species as a model to understand the evolution of the endocrine system.

New tactics for repelling, controlling disease-carrying insects

In the battle between insect predators and their prey, chemical signals called kairomones serve as an early-warning system. Pervasively emitted by the predators, the compounds are detected by their prey, and can even trigger adaptations, such a change in body size or armor, that help protect the prey. But as widespread as kairomones are in the insect world, their chemical identity has remained largely unknown. New research by Rockefeller University's Joel E. Cohen and colleagues at the University of Haifa in Israel has identified two compounds emitted by mosquito predators that make the mosquitoes less inclined to lay eggs in pools of water.

Human impact on health of soil, and impact of unhealthy soil on society are intertwined, says LSU researcher

It may sound counterintuitive, but LSU Associate Professor of Chemistry Robert Cook has made a career out of studying the ways organic materials found in the environment, including soils, can either get dirty or stay clean. In fact, the National Science Foundation, or NSF, was so impressed with his efforts that the funding institute awarded Cook one of its most prestigious awards - the NSF CAREER award.

All dementia isn't Alzheimer's disease: Mayo Clinic

Occasional misplaced keys or forgotten names don't mark the beginning of dementia. All dementia isn't Alzheimer's disease. Some dementia symptoms can be reversed. Those facts and many more are covered in Deciphering Dementia, a supplemental Special Report to the July issue of Mayo Clinic Women's HealthSource

Two-thirds of world's population are vitamin D-insufficient or deficient

Vitamin D surfaces as a news topic every few months. How much daily vitamin D should a person get? Is it possible to have too much of it? Is exposure to the sun, which is the body's natural way of producing vitamin D, the best option? Or do supplements suffice?

Spanish scientists develop new parasite detection method to prevent Anisakidosis

A new method enables anisakids to be detected in any fish product, from a whole fish, fresh or frozen, to tinned fish and surimi. Developed by Spanish scientists, the system is based on molecular techniques and overcomes the limitations of traditional procedures.

Enzyme mTOR regulates autophagy: Study

Cells that consume parts of themselves can stop this process autonomously as well. This was discovered by NWO researcher Judith Klumperman's group, in collaboration with colleagues from the National Institute of Health in Washington. The self-cannibalism is part of the normal digestive process of the cell, but also a survival mechanism in times of famine. This is what makes it difficult for doctors to 'starve out' cancer cells, for instance. The research results were published on 6 June in Nature.

High levels of mercury in fish can cause adverse health effects

Mercury levels in a popular species of game fish in Lake Erie are increasing after two decades of steady decline, scientists are reporting. The study, the most comprehensive to date on mercury levels in Great Lakes fish, is in ACS' Environmental Science & Technology, a semi-monthly journal.

Experts use Mexican aquatic salamander to study evolution and genetics of stem cells

Dr Andrew Johnson is speaking today (12 July) at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells - research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell therapies. This team has found that there are extraordinary similarities in the development of axolotls and mammals that provide unique opportunities to study the properties of embryonic stem cells and germ cells.

Subtle mutation affecting epigenome may lead to inherited form of mental retardation: Researchers

A subtle mutation affecting the epigenome –- a set of dynamic factors that influence gene activity -- may lead to an inherited form of mental retardation that affects boys, find researchers at Children's Hospital Boston. The disorder, which also involves cleft lip or cleft palate, appears to hinge on an enzyme working in a biological pathway that may offer several potential drug targets.

Thermo Fisher Scientific announces new methods to detect petroleum contamination in oysters and fish

Thermo Fisher Scientific Inc., the world leader in serving science, today announced that its global Food Safety Response Center located in Dreieich, Germany, has developed two new analytical screening methods to detect petroleum contamination in oysters and fish, specifically hydrocarbons and poly-aromatic hydrocarbons (PAHs), resulting from the oil spill in the Gulf of Mexico.

Researchers report how mature red blood cells form

We take our blood for granted, but its creation requires a complicated series of steps, starting with the formation of blood stem cells during early embryonic development, followed by progressive differentiation into the progenitors of red cells, white cells and platelets, and ultimately the full set of blood cells.
