Starvation Effects Handed Down for Generations

July 31, 2015 — Starvation early in life can alter an organism for generations to come, according to a new study in nematodes. The epigenetic effects are a 'bet-hedging strategy.' Famine survivors are ... read more

Gene Drive Research: Safeguarding the Greater Good

July 30, 2015 — Research teams have proactively assembled an international group of 26 experts, including prominent genetic engineers and fruit fly geneticists, to unanimously recommend a series of preemptive ... read more

July 29, 2015 — Researchers have developed a smartphone test for chlamydia that can detect the disease with high accuracy, which could reduce the prevalence of this sexually transmitted disease (STD) by making ... read more

Understanding Molecular Origin of Epigenetic Markers

July 28, 2015 — Researchers have determined the mechanics behind of one of the most common epigenetic modifications: histone-tail acetylation. Acetylation is a means by which a cell can control the expression of its ... read more

Fatty Acid Increases Performance of Cellular Powerhouse

July 28, 2015 — An entirely new control mechanism that regulates the function of mitochondria, the powerhouses of the cell, has been discovered by researchers. Surprisingly, a fatty acid is playing a key role in ... read more

Ewing's Sarcoma: A Dangerous Liaison

July 28, 2015 — Researchers have elucidated at the molecular level how an otherwise innocuous inherited mutation that is quite common in European populations interacts with a spontaneous somatic mutation to promote ... read more

July 28, 2015 — A new technology is improving the efficiency of the studies in epigenomics. The examination of epigenomes requires mapping DNA interactions with a certain protein in the entire genome. This ... read more

Ancient Proteins Involved in DNA Repair Could Shed Light on Tumor Development

July 28, 2015 — By studying yeast used in beer- and bread-making, researchers have uncovered the mechanism by which ancient proteins repair DNA damage and how their dysfunction could lead to the development of ... read more

Researchers Create Promising New Mouse Model for Lung Injury Repair

July 28, 2015 — Researchers have created a dynamic functional mouse model for lung injury repair, a tool that will help scientists explain the origins of lung disease and provide a system by which new therapies can ... read more

New Treatment Options for a Fatal Leukemia

July 27, 2015 — In industrialized countries, acute lymphoblastic leukemia is the most common form of cancer in children. An international research consortium has now succeeded in decoding a specific form of this ... read more

DeepBind Predicts Where Proteins Bind, Uncovering Disease-Causing Mutations

July 27, 2015 — A new tool called DeepBind uses deep learning to analyze how proteins bind to DNA and RNA, allowing it to detect mutations that could disrupt cellular processes and cause ... read more

Predicting Whether Children With DiGeorge Syndrome Will Develop Autism or Psychosis

July 27, 2015 — New findings are the first to suggest a potential way to predict whether children with DiGeorge syndrome will develop one of two mental impairments. The researchers report having isolated specific ... read more

July 24, 2015 — Scientists have unraveled how an important plant protein, known as TOPLESS, interacts with other molecules responsible for turning genes off. The findings in plants provide a general model across ... read more

Scientists Discover First 'DNA Ambulance'

July 24, 2015 — Researchers have discovered how severely damaged DNA is transported within a cell and how it is repaired. It's a discovery that could unlock secrets into how cancer ... read more

Researchers Discover New Role for Protein in Cell Division

July 23, 2015 — Pharmaceutical sciences researchers have discovered a protein's previously unknown role in cell division. The well known protein ATF5 controls how often specific genes are copied from DNA. But ... read more

Innovative Algorithm Is Helping Scientists Decipher How Drugs Work Inside the Body

July 23, 2015 — Researchers have developed a computer algorithm that is helping scientists see how drugs produce pharmacological effects inside the body. The study could help researchers create drugs that are more ... read more
