Families where children are born without a genetic or gestational link to their parents are functioning well

The emotional well-being of families where children lack a genetic or gestational link to one or both of their parents - where the children have been conceived through surrogacy, egg donation or donor insemination - has long been a subject of debate.

Surrogacy still stigmatised, though attitudes changing among younger women

Although younger people are becoming more positive towards surrogate mothers, current day attitudes to surrogacy are still broadly negative, a scientist will tell the 24th annual conference of the European Society of Human Reproduction and Embryology.

Gene technique that alters CCR5-producing gene increases resistance to HIV in mice

Altering the gene that produces CCR5 protein on the surface of immune cells using a harmless virus was found to significantly increase resistance to HIV in mice, according to a study published Sunday in the journal Nature Biotechnology, the Press Trust of India reports (Press Trust of India, 7/1).

Microchip-based device determines the genetic signature of lung tumors

Massachusetts General Hospital (MGH) investigators have shown that an MGH-developed, microchip-based device that detects and analyzes tumor cells in the bloodstream can be used to determine the genetic signature of lung tumors, allowing identification of those appropriate for targeted treatment and monitoring genetic changes that occur during therapy. A pilot study of the device called the CTC-chip will appear in the July 24 New England Journal of Medicine and is receiving early online release.

New computational tool to study complex clusters of genes

Two Texas A&M University researchers have developed a computational tool that will help scientists more accurately study complex units of clustered genes, called operons, in bacteria.

Computational research hones cancer-fighting strategies

A Florida State University faculty member who uses computational techniques to evaluate a new class of cancer-killing drugs is attracting worldwide attention from other researchers.

Genetic link between Crohn's and asthma discovered

Research into the genetic causes of Crohn's disease has revealed that the gene ORMDL3, known to be a risk factor for childhood asthma, is also associated with Crohn's disease, and in the process links between the condition and other diseases have been found.

Mouse embryonic stem cells used to build heart parts

Researchers have shown that they can put mouse embryonic stem cells to work building the heart, potentially moving medical science a significant step closer to a new generation of heart disease treatments that use human stem cells.

Old order Amish, Mennonites reject health insurance, face high costs for care at not-for-profit hospitals

Old Order Amish and Mennonites in Lancaster County, Pa., "suffer from endemic proportions of certain deadly genetic diseases" because they do not marry outside their communities, and, as they "seek lifesaving treatments, the uninsured in these Pennsylvania communities are struggling with escalating costs of care" at not-for-profit hospitals, the Wall Street Journal reports.

Type 1 diabetes on the rise in Australian children

A new report from the Australian Institute of Health and Welfare (AIHW) has revealed a worrying increase in the rate of type 1 diabetes in Australian children.

UVB does more damage to DNA than UVA

As bombs burst in air this July 4, chances are that sunburn will be the red glare that most folks see - and feel. But unfortunately, even when there is no burn, the effects of the sun's ultraviolet (UV) rays can have deadly consequences.

New technique produces genetically identical stem cells

Adult cells of mice created from genetically reprogrammed cells-so-called induced pluripotent stem (IPS) stem cells-can be triggered via drug to enter an embryonic-stem-cell-like state, without the need for further genetic alteration.

New clues to the biological basis of migraines

Fifteen percent to 20 percent of people worldwide suffer from migraines - excruciating headaches often presaged by dramatic sensations, or "auras." By studying a rare, inherited form of migraine, researchers at Vanderbilt University Medical Center have found clues to the biological basis of the painful, debilitating disorder.

Children's Brain Tumor Foundation's tissue bank consortium may solve dire problem in pediatric cancer research

In a major effort to speed treatment and cures for pediatric brain tumors and cancer, the Children's Brain Tumor Foundation (CBTF) today launched the initial phase of a tissue bank consortium designed to jump-start meaningful analyses that could lead to treatment and cures for these types of cancer, where survival rates are unacceptably low and neurocognitive and other damage is posed by today's treatment options.

Electrostatic-based RNA assays technique could revolutionize medical diagnostics

The dream of personalized medicine - in which diagnostics, risk predictions and treatment decisions are based on a patient's genetic profile - may be on the verge of being expanded beyond the wealthiest of nations with state-of-the-art clinics.

Scientists fortify the cassava plant - a day's nutrition in a single meal

Scientists have determined how to fortify the cassava plant, a staple root crop in many developing countries, with enough vitamins, minerals and protein to provide the poor and malnourished with a day's worth of nutrition in a single meal.

A global DNA barcode database

The idea of barcoding is familiar to many: in almost every supermarket the checkout operator shows the ticket labelled with a series of black bars to a laser scanner which responds with a beep; a computer analyses the code, identifies the product and the price is sent to the till.

Novel approach for treating mitochondrial disorders wins Kaye prize

A novel concept for the treatment of mitochondrial disorders using directed enzyme replacement therapy (DERT) has won for a Hebrew University of Jerusalem doctoral candidate one of this year's Kaye Innovation Awards. The awards were presented at this year's 71st meeting of the Hebrew University Board of Governors.

Scientists discover how an injured embryo can regenerate itself

More than 80 years have passed since the German scientist Hans Spemann conducted his famous experiment that laid the foundations for the field of embryonic development. After dividing a salamander embryo in half, Spemann noticed that one half - specifically, the half that gives rise to the salamander's 'belly' (ventral) starts to wither away.

Faulty DNA repair could be a risk factor for lung cancer in nonsmokers

People who have never smoked but whose cells cannot efficiently repair environmental insults to DNA are at higher risk of developing lung cancer than those with effective genomic repair capability, according to researchers from the Department of Epidemiology at The University of Texas M. D. Anderson Cancer Center.
