Overzealous Plant Immune System Can Be Deadly

Scientists from the Max Planck Institute for Developmental Biology have now pinpointed the most common culprits for autoimmunity in plants. Plants are under permanent attack by a multitude of pathogens. To win the battle against fungi, bacteria, viruses and other pathogens, they have developed a complex and effective immune system. And just as in humans, […]

Engineered Bacteria Can Store Memories of Chemical Exposure

New research from MIT reveals that engineered E. coli can store long-term memories of chemical exposure and other events in their DNA. MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications […]

Native Lizards Show Rapid Fire Evolution

A newly published study from Harvard University found that in just 20 generations in 15 years green anoles evolved larger toe pads equipped with more sticky scales to allow for better climbing. Though it’s often portrayed as a process that takes place over thousands of years, under the right circumstances the evolution of enhanced traits […]

Algorithm Can Predict the Evolution of Viruses

Using the branches of a genealogical tree as reference, a team of scientists has developed an algorithm that can predict the evolution of asexual organisms such as viruses or cancer cells. For a long time, prognoses forecasting the evolutionary future of organisms were considered mere speculation. Together with researchers from Cambridge and Santa Barbara, USA, […]

Ancient Family of Sthenurine Kangaroos Likely Preferred Walking to Hopping

Based on a rigorous comparative analysis of kangaroo anatomy, biologists at Brown University reveal that the ancient family of sthenurine kangaroos likely preferred walking to hopping. Imagine that a time machine has transported you to the Australian outback 100,000 years ago. As you emerge, you see a huge kangaroo with a round rabbit-like face foraging […]

Researchers Discover a New Signaling Pathway to Combat Excess Body Weight

An international team of researchers has discovered a new signaling molecule capable of activating brown fat cells. The number of overweight persons is greatly increasing worldwide – and as a result is the risk of suffering a heart attack, stroke, diabetes or Alzheimer’s disease. For this reason, many people dream of an efficient method for […]

Study Reveals Embryos Receive Parent Specific Layers of Information

New research from San Francisco State University sheds light on the multilayered process of how a sperm and egg pass along information needed for successful reproduction, revealing that embryos receive parent-specific layers of information. The information that interprets the genetic code in a new embryo differs depending on whether it comes from the father or […]

Surveillance of Nuclear Pore Complex Assembly

In a newly published study, Yale biologists and colleagues describe a key quality control mechanism that protects new cells from inheriting defective nuclear pore complexes. As befitting life’s blueprint, DNA is surrounded by an elaborate security system that assures crucial information is imparted without error. The security is provided by a double membrane perforated by […]
