NIH renews grant to continue cell growth regulation research

The new year began on a high note for Alan Leonard and Julia Grimwade, professors of biological sciences at Florida Institute of Technology, when they learned their National Institutes of Health grant, which they have held for the last 11 years, had been renewed for four more years. The competitive renewal brings them $1,024, 944 to continue their research into the regulation of cell growth and division.

Researchers devise method to pinpoint key genetic variations under positive natural selection that may impact human health

Fossils may provide tantalizing clues to human history but they also lack some vital information, such as revealing which pieces of human DNA have been favored by evolution because they confer beneficial traits - resistance to infection or the ability to digest milk, for example. These signs can only be revealed through genetic studies of modern humans and other related species, though the task has proven difficult.

Study to understand acoustic communication across animal species

Scientists who compare insect chirps with ape calls may look like they are mixing aphids and orangutans, but researchers have found common denominators in the calls of hundreds of species of insects, birds, fish, frogs, lizards and mammals that can be predicted with simple mathematical models.

UAE hosts five-day global health conference

Public health experts and researchers from around the world gathered on Monday for a five-day conference at the United Arab Emirates University (UAEU) in Al Ain, UAE, to discuss the role of the Middle East in tackling global health issues, AMEinfo.com reports.

Discovery of inhibitory hormone may yield new treatments for cancer and other diseases

Nearly 10 years after the discovery that birds make a hormone that suppresses reproduction, University of California, Berkeley, neuroscientists have established that humans make it too, opening the door to development of a new class of contraceptive and possible treatments for cancer or other diseases.

Embryo biopsy safe for singleton pregnancies

The largest and longest running study of children born after preimplantation genetic diagnosis and screening has shown that embryo biopsy does not adversely affect the health of babies born as the result of a subsequent singleton pregnancy.

Scientists offer potential new way to combat malaria

Stopping male mosquitoes from sealing their sperm inside females with a 'mating plug' could prevent mosquitoes from reproducing, and offer a potential new way to combat malaria, say scientists publishing new results in PLoS Biology on 22 December.

Tufts researchers discover new neuron development in nulliparous mothers

Maternal behavior itself can trigger the development of new neurons in the maternal brain independent of whether the female was pregnant or has nursed, according to a study released by researchers at Tufts University's Cummings School of Veterinary Medicine.

New technology sheds light on intracellular transport

Using new technology developed in his University of Oregon lab, chemist Andrew H. Marcus and his doctoral student Eric N. Senning have captured what they describe as well-orchestrated, actin-driven, mitochondrial movement within a single cell.

Pure populations of immature cells that enable male reproduction isolated and transplanted

Reproductive researchers from the University of Pennsylvania and The Children's Hospital of Philadelphia have succeeded in isolating and transplanting pure populations of the immature cells that enable male reproduction in two species-human spermatogonia and mouse gonocytes. These germline stem cells, taken from testis biopsies, demonstrated viability following transplantation to mouse testes within a controlled laboratory setting.

Scientists present new research on adipocyte regulation

The ninth Colloque Médecine et Recherche of la Fondation Ipsen devoted to Endocrinology, held in Paris on December 4, 2009, has reviewed the recent progress in understanding the regulation of fat storage in the body and the consequences of the breakdown of this regulation.

Scientists evaluate current research on soy infant formula

Members of the media are invited to attend a press availability period at noon on Friday, December 18, 2009 that will follow a scientific meeting evaluating the safety of soy infant formula. An independent panel of 14 scientists will evaluate the most current research on soy infant formula to determine whether exposure to soy infant formula is a risk to human development.

Smell and sexual reproduction

Humans have the same receptors for detecting odors related to sex as do other apes and primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to Duke University researchers.

Researchers discover new strategy against invasive parasite

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a possible strategy against an invasive parasite that infects more than a quarter of the world's population, including 50 million Americans.

New book presents latest research on neuroendocrine physiology

In this volume an international group of basic and clinical investigators presents their latest research on neuroendocrine physiology, advances in the control of the onset of puberty and its disorders, and basic and clinical aspects of the GH/IGF-1 and hypothalamic-pituitary-adrenal axes. An entire section is dedicated to pituitary tumors, including genetics and neuroimaging, and another covers the neuroendocrine control of substrate metabolism, including hypothalamic obesity and anorexia.

Protein ERK oscillates between two major compartments in breast tissue cells

Time-lapsed video of individual breast tissue cells reveals a never-before-seen event in the life of a cell: a protein that cycles between two major compartments in the cell. The results give researchers a more complete view of the internal signals that cause breast tissue cells to grow, events that go awry in cancer and are targets of drug development.

Sperm genes may have a detrimental effect on longevity, says new study

Researchers in Japan have found that female mice produced by using genetic material from two mothers but no father live significantly longer than mice with the normal mix of maternal and paternal genes. Their findings provide the first evidence that sperm genes may have a detrimental effect on lifespan in mammals.
