Algorithm predicts risk of developing Alzheimer’s Disease prior to onset of symptoms.

August 30th, 2017

It is well known that Mild cognitive impairment(MCI) may increase your risk of later progressing to dementia, caused by Alzheimer’s disease or other neurological conditions. But some people with mild cognitive impairment never get worse, and a few eventually get better. Until now there was no way to tell who with MCI would develop Alzheimer’s Disease and who would not. Scientists from McGill have developed an algorithm that can potentially fulfill the need.

DNA Methylation data can help predict human mortality

October 5th, 2016

Have you ever wondered why some people who live healthy lifestyles died younger than peers who are much less health conscious?

Researchers from the University of California-Los Angeles (UCLA) may have gotten closer to the answer, they studied the correlation of epigenetics and premature ageing and found that independent of chronological age, those with an accelerated epigenetic age died sooner.

Genetic Variants Can Actually Cause "Vibration Allergies"

February 5th, 2016

For some people, the most everyday tasks–riding in a car, or drying your hands with a towel–can lead to rashes and hives, a condition known as vibratory urticaria. Researchers discovered a rare variant present in affected individuals that appears to be correlated with a pronounced release of inflammatory chemicals in response to vibration signals. Most people react far less dramatically
Bed bug
Bed bug Genome is Sequenced, With Close Ties to Bacteria

February 2nd, 2016

Growing concerns over the parasitic, blood-sucking bed bug prompted researchers to map the genome of C. lectularius, one of the most common species. They discovered ~800 possible instances of lateral gene transfer between the DNA of bacteria hosted within its own body. Scientists were surprised to find that at least one of these genes were functional–even useful–in males

Indian Subcontinent Shown to Contain 5 Dominant Ancestries

January 25th, 2016

Past analyses of limited population samples led to the hypothesis that there were only two fundamental ancestral components in native to the Indian subcontinant. A new study, published by PNAS now reveals at least four major ancestries in the mainland, and a fifth type endemic to surrounding islands with ties to Oceania

Hajdu-Cheney syndrome
A Genetic Variant Causes Bone To Be Absorbed By Cells

January 14th, 2016

Hajdu-Cheney syndrome is a rare disorder, partially characterized by a permanent loss of bone tissue over time. New research suggests that the cause of this disease is an overabundance of cells that actually absorb the bone tissue before it can be replaced. Scientists hope that mice models can shed light on similar disorders
Ash Tree
The British Take A Genomic Approach to Ash Dieback

January 14th, 2016

The last few years have been difficult for lovers of the ash tree across England. Since 2012 a fungal pathogen has been spreading across ash trees in the UK, resulting in a staggering 98% mortality rate in some areas. An RNA-seq study led by researchers at the University of York identified several genes whose expression levels are correlated with symptoms of fungal infection

Ancient Remains Unravel Origins of Modern Irish Genome

January 5th, 2016

The development of agriculture, and later of metallurgy, were major upheavals to the people of Europe. In order to determine what effect these shifts may have had on the people of Ireland, researchers sequenced the genome of ancient Irish remains and compared it with other peoples across Europe

Golden Retriever
Domesticated Canines May Have Originated in Central Asia

October 20, 2015

In another attempt to trace the geographical origin of the modern dog, researchers probed the genomes of over 5,000 dogs from around the world. The DNA evidence suggests that dog domestication occurred in Central Asia, then spread outward. There are, however, several conflicting arguments on this point
Fire Ant
Queens and Workers in Wasps & Ants Aren't So Different

October 19, 2015

What do dinosaur ants and red paper ants have in common? For starters, both are eusocial species in which the the differences in gene expression between workers and queens are surprisingly small. Unlike honeybees, workers have the ability to transform into queens, and are physiologically indistinguishable from one another
Scientists Identify New Risk Factors For Bowel Cancer

October 16, 2015

While bowel cancer is in itself a dangerous and potentially fatal condition, not knowing its chances of recurrence can be equally worrisome. Researchers from Baylor University have recently identified heightened experssion of an RNA in patients that experience bowel cancer recurrence after treatment

The latest 10-question quiz on the Science website is a helpful way to learn the latest discoveries and developments in genetics, zoology, and astronomy. Each question leads to a summarized report and can direct you toward additional information
Ape-Specific Malaria Parasites Share DNA Across Species

October 12, 2015

New research indicates that species-specific malaria parasites share essential DNA segments that allow the pathogen to pass through the bloodstream undetected. Since the greater apes diverged from each other millions of years ago, this indicates that the origins of malaria are more ancient than previously thought
Heightened Apoptosis Reduces Cancer Risk in Elephants

October 9, 2015

Theoretically, the cancer rate of a species should generally increase with the number of cells it possesses. Elephants, however, show a surprisingly low cancer rate for their masive size. Latest research demonstrates that this is partially due to an extroardinary ability to induce aptosis, or “programmed cell death,” of infected cells

Ancient Migration Art
Ancient African Genome Suggests Massive Inward Migration

October 9, 2015

Sequencing preserved DNA from ancient reamins is a valuable method of mapping acient migrations. The latest genome sequencing of an ancient Ethopian man now suggests that, in addition to the massive migration from Africa, there was subsequntly a substantial movement back into the continent from Middle Eastern farmers

Newly-Discovered Mutations Cause Forms of Color Blindness

October 2, 2015

When the concerned owners of a German shepard brought their pet to an animal hospital, they found that he had a rare vision disorder known as achromatopsia, which affects both color perception and overall clarity. Genomic analysis identified a mutation not previously known, and it was found to exist in humans as well
Snakes Retain DNA Linked to Development of Limbs

October 1, 2015

In genomic terms, enhancers are regions of noncoding DNA that regulate expression of certain genes. Recently, scientists have discovered that enhancers previously thought to be responsible for limb development are also involved in the development of a phallus in snakes. Further research confirmed the involvement of these enhancers in phallic development in other species as well

Ancestry of Neuron Evolution Can Be Found In their DNA

October 1, 2015

Just as variability in a person’s DNA has the potential to reveal their ancestral origins, mutations in the DNA of individual neuron cells can potentially trace its lineage from the original stem cells. Scientists have found that these mutations often arise due to increased use of the cells themselves, rather than degeneration from lack of use

Genetic Screening Detects Usefulness of Chemotherapy

September 26, 2015

Black rice, also known as “Emperor’s rice” or
Forbidden rice,” was prized for its unique pigmentation and health benefits. In an attempt to track down the genetic origins of these grains, Japanese biologists examined DNA samples and found that their unique pigmentation was due to the rearrangement of a gene involved in the production of anthocyanis
