New evidence of a genetic reason for autism

The causes of autism are varied. However one reason for some people with an autism spectrum disorder is likely to be genetic. New research has identified a new genetic cause.

Essential Science: Zeroing in on a gene that stops you drinking

A large study has pinpointed a gene variant that suppresses the desire of a person to drink alcohol. The next question is whether the discovery can be used for medicinal purposes.

Genetics reveals my some people have 'wild hair'

Berlin - Struggling with unmanageable hair? Struggling with hair that won't style or comb? The various states of uncomfortable hair have been attributed, in new scientific research, to genetics.

One bull gave rise to two million great-grandaughters

One bull, called Pawnee Farm Arlinda Chief, had more than two million great-granddaughters, making him the most successful bovine in history. However, it also appears he had a genetic defect and this has spread through Holstein populations.

Scientists map the ‘dark matter’ of DNA

Saarland - Understanding DNA variations can inform about health risks and it can also provide the basis for personalized medicine. There are still some knowledge gaps — which some call the ‘dark matter' of DNA.

Can genetics explain our food preferences?

Meat, vegetables or fish? Whether craving pasta or a chocolate bar our food preferences appear to have a genetic basis, according to a new study.

Modified bacteria protect against obesity

Introducing genetically modified bacteria into the intestines of mice appears to protect the rodents from obesity. This could become a treatment option for people.

Scientists think it's possible to reverse the aging process

The fountain of youth may be a myth but a gene called Nanog might lead to the same effect. A new research breakthrough could bring with it treatments for conditions like atherosclerosis, osteoporosis and Alzheimer’s.

It’s all in the genes: Why some chickens are bird flu resistant

Lincoln - Combating the risks associated with bird flu is of global importance. While some research focuses on treatment, and other parts on addressing transmission, another strand looks at patterns of susceptibility.

Will three-parent genes increase life expectancy?

Studies using mice, where pups have been born with genes from three parents, have shown that the mice live longer. Scientists are discussing whether such a longevity effect would be seen with people.

New genetic link to early onset Alzheimer’s

Australian researchers have found a connection between early onset Alzheimer’s disease and a type of genetic mutation. This could signal a new direction for research into the disease.

AstraZeneca to sequence 2 million genomes

Pharmaceutical company AstraZeneca is to embark on an ambitious project that will see the drugs giant sequence 2 million genomes in the quest for new candidate drug products.

Is CRISPR technology set to change biological science?

Gene editing technology is seemingly the most important scientific method to emerge in recent years. The primary method is called CRISPR and it is transforming the field of biology.

Essential Science: Semi-synthetic bacterium created

Scientists have created a semi-synthetic, functioning bacterium in the lab that has fewer than 500 genes. The importance of "500" is that no bacterium in nature has less than 500 genes.

New study draws genetic & inflammatory disease connection

A new study has revealed that hundreds of genes are linked to five key inflammatory diseases. The diseases are: ankylosing spondylitis, Crohn's Disease, ulcerative colitis, psoriasis, and primary sclerosing cholangitis.

Newly discovered genetic error may stop heart attacks

Heart attacks can be caused by lifestyle, diet and genetics. With genes, some people are at a greater risk than others. A new study has revealed a new genetic clue.

Animal diversity urgently needed for the future

London - According to a new United Nations report, animal biodiversity is needed to improve production and food security on a warmer, more crowded planet.

Researchers claim to have reversed autism

Neuroscientists think it may be possible to reverse the symptoms of one type of genetic associated autism. This is based on pinpointing a missing gene needed for brain development.

The food we eat influences our genes

A new study suggests human genes are influenced by the food that is eaten. This is based on a microbiological study, examining genetics and metabolism.

New techniques can identify spiders from their webs

Advancements in genetic techniques have led to researchers being able to identify black widow spiders from their webs. The method allows researchers not only to identify the spider, but also its prey.

What you need to know about gene editing success in U.S.

New York - Scientists have successfully used gene editing techniques to treat mice with the genetic condition Duchenne muscular dystrophy.

Genetically modified mice see rise in intelligence

Leeds - Researchers have succeeded in genetically engineering mice to produce rodents of greater intelligence and less anxiety. The research could one day help those with post-traumatic stress disorder.

Mistletoe is genetically different to other plants

Mistletoe has been found to be made-up in a slightly different way to other plants or animals: it is missing several key genes needed for energy production in cells.

Computer solves 120-year-old mystery of worms in three days

A computer has solved a mystery that has been puzzling scientists for over 120 years in just three days. Using complex predictive simulation software, the system managed to explain how sliced-up worms turn into independent organisms.

What you need to know when volunteering for a genetic study

Would you volunteer for a genetic study? If so would you want to know if you had a rare disease? It seems that, for most people, the answer is "yes."

Remote tribespeople carry antibiotic resistant genes

Washington D.c. - Researchers have discovered antibiotic resistance genes in the bacteria of a South American tribe never exposed to antibiotic drugs. This suggests some bacteria have always been antibiotic resistant.

Should human germline modification be halted? Special

Following recent reports about experiments on embryos, the Center for Genetics and Society is calling for a halt to experiments aimed at the creation of genetically modified human beings.

Are eating disorders genetic?

Mice lacking a gene implicated in human anorexia and bulimia weigh less than other mice. Such animals also display a variety of behavioral disorders. This points to a genetic basis for eating disorders.

How many recessive lethal mutations do we carry?

Scientists report an estimate of the average number of recessive lethal mutations people carry. The figures are quite surprising.
