Ancient DNA Ends Aussie Claim to Kiwi Origins

May 23, 2014 10:37 am | News | Comments

Australia can no longer lay claim to the origins of the iconic New Zealand kiwi following University of Adelaide research showing the kiwi's closest relative is not the emu as was previously thought. Instead, the diminutive kiwi is most closely related to the extinct Madagascan elephant bird.

Genes Link Circadian Clock to Eating Schedule

May 22, 2014 1:51 pm | Videos | Comments

Scientists have discovered a pair of genes that normally keeps eating schedules in sync with daily sleep rhythms, and, when mutated, may play a role in so-called night eating syndrome.                   

Genes Successfully Predict Alcoholism Risk

Researchers Sequence Genome of Primitive Termite

May 21, 2014 11:00 am | News | Comments

North Carolina State University entomologists are part of a research team that has for the first time sequenced the genome of a member of the termite order, the dampwood termite. The findings on the genetic blueprint of the dampwood termite, one of the world’s most primitive social insects, highlight key differences and similarities with other social insects like ants, wasps and bees, and provide insight into how social insects evolved.

Humpback Whale Subspecies Revealed by Genetic Study

May 21, 2014 10:42 am | News | Comments

A new genetic study has revealed that populations of humpback whales in the oceans of the North Pacific, North Atlantic and Southern Hemisphere are much more distinct from each other than previously thought, and should be recognized as separate subspecies. Understanding how connected these populations are has important implications for the recovery of these charismatic animals that were once devastated by hunting.

Scientists Develop New Approach for Sampling Gut Bacteria

May 20, 2014 12:52 pm | News | Comments

Scientists at Forsyth, Massachusetts General Hospital and the Harvard School of Public Health have developed a new protocol for collecting saliva and stool samples for genomic and transcriptomic analyses. This method eliminates the need for specialized personnel and facilities while keeping the sample intact. It also provides critical insight into the genetic makeup of the microbiome of the digestive tract.

Mothers' Sleep, Late in Pregnancy, Affects Offspring's Weight Gain as Adults

May 19, 2014 2:32 pm | News | Comments

Poor-quality sleep during the third trimester of pregnancy can increase the odds of weight gain and metabolic abnormalities in offspring once they reach adulthood, according to a new study. Researchers linked the excess weight and changes in metabolism to epigenetic modifications that reduce expression of the gene for adiponectin—a hormone that helps regulate several metabolic processes, including glucose regulation.

Risk of Brain Injury is Genetic

May 19, 2014 1:03 pm | News | Comments

Premature babies’ risk of brain injury is influenced by their genes, a new study suggests. The researchers have identified a link between injury to the developing brain and common variation in genes associated with schizophrenia and the metabolism of fat.

Interactions May Matter Most for Longevity

May 16, 2014 10:48 am | News | Comments

If studying a single gene or a diet that might extend longevity is like searching for a fountain of youth, then a new study calls for looking at something more like the whole watershed. Brown University biologists who experimentally throttled three such factors in fruit flies found that lifespan depended more on interactions among the factors than on the factors themselves.

Breaking News: Genes May Verify Earliest American Inhabitants

May 15, 2014 2:12 pm | News | Comments

A new study uses genetic information extracted from the remains of an adolescent girl to help resolve the longstanding debate about the origins of the first people to inhabit the Americas.                  

Researchers ID Gene That Causes Obesity-related Metabolic Syndrome

May 15, 2014 11:05 am | News | Comments

New research has identified a genetic mutation responsible for the cluster of cardiovascular risk factors that comprise the obesity-related metabolic syndrome.                          

Breastfeeding May Lower Ovarian Cancer Risk in Women with BRCA Mutations

May 14, 2014 12:50 pm | News | Comments

Breastfeeding, tubal ligation– also known as having one’s “tubes tied”– and oral contraceptives may lower the risk of ovarian cancer for some women with BRCA gene mutations, according to a new comprehensive analysis.          

It’s All in the Genes, but Whose?

May 13, 2014 1:12 pm | News | Comments

Researchers argue that biologists trying to explain the connection between genotype and phenotype need to consider yet another factor: genetic material that doesn’t come from an organism’s chromosomes at all.

Breaking News: Genetic Marker Linked to OCD

May 13, 2014 9:11 am | News | Comments

A group of researchers say they have identified a genetic marker that may be associated with the development OCD, the causes and mechanisms of which are some of the least understood among mental illnesses.            

Atlas Shows How Genes Affect Our Metabolism

May 12, 2014 2:10 pm | News | Comments

In the most comprehensive exploration of the association between genetic variation and human metabolism, researchers have provided unprecedented insights into how genetic variants influence complex disease and drug response through metabolic pathways. The team has linked 145 genetic regions with more than 400 molecules involved in human metabolism in human blood.

Immune Therapy Might be Effective for Multiple Myeloma

May 12, 2014 1:32 pm | News | Comments

A new study provides evidence that genetically modifying immune cells might effectively treat multiple myeloma, a disease that remains incurable and will account for an estimated 24,000 new cases and 11,100 deaths in 2014.        

Autism-related Protein Plays Vital Role in Addiction

Investigators report that a gene essential for normal brain development, and previously linked to Autism Spectrum Disorders, also plays a critical role in addiction-related behaviors.                   

Expanding the Power of RNA Interference

May 12, 2014 1:12 pm | News | Comments

Using nanoparticles designed and screened for endothelial delivery of short strands of RNA called siRNA, researchers were able to target RNAi to endothelial cells, which form the linings of most organs. This raises the possibility of using RNAi to treat many types of disease.

Man's Best Friend Shares Similar 'Albino' Gene

May 12, 2014 1:05 pm | News | Comments

Dopamine Turns Worker Ants into Warrior Queens

May 12, 2014 12:51 pm | News | Comments

The ritualized fighting behavior of one ant species is linked to increases in dopamine levels that trigger dramatic physical changes in the ants without affecting their DNA. The researchers studied Indian jumping ants (Harpegnathos saltator), which can undergo significant changes in physiology without any related changes to their DNA. Instead, the changes depend on which genes are turned on or off.
