Small molecules change biological clock rhythm
A team of chemists and biologists at the Institute of Transformative Bio-Molecules (ITbM), Nagoya University have succeeded in finding new molecules that change the circadian rhythm in mammals by applying synthetic chemistry methods, which makes use of highly selective metal catalysts. Most living organisms have a biological clock with an approximately 24-hour circadian rhythm, which regulates important body functions such as sleep/wake cycles, hormone secretion, and metabolism. Disruption of...

Spider and centipede venom evolved from insulin-like hormone
Funnel-web spider venom contains powerful neurotoxins that instantly paralyze prey (usually insects). Millions of years ago, however, this potent poison was just a hormone that helped ancestors of these spiders regulate sugar metabolism, similar to the role of insulin in humans. Surprisingly, this hormone's weaponization--described on June 11 in the journal Structure--occurred in arachnids as well as centipedes, but in different ways. Researchers at the University of Queensland in Australia...

Why human egg cells don't age well
When egg cells form with an incorrect number of chromosomes--a problem that increases with age--the result is usually a miscarriage or a genetic disease such as Down syndrome. Now, researchers at the RIKEN Center for Developmental Biology in Japan have used a novel imaging technique to pinpoint a significant event that leads to these types of age-related chromosomal errors. Published in Nature Communications, the study shows that as egg cells mature in older women, paired copies of matching...

DNA protection, inch by inch
DNA within reproductive cells is protected through a clever system of find and destroy: new research published in Cell Reports today lifts the veil on how this is done. A European team of scientists has discovered how the cells produce tiny pieces of RNA - called piRNA - that identify and silence 'jumping genes' or transposons: genes that are able to change their position within the genome and therefore alter or disrupt the genetic code. Comprising just 30 letters of genetic code, piRNA are...

Biodiversity: 11 new species come to light in Madagascar
Madagascar is home to extraordinary biodiversity, but in the past few decades, the island's forests and associated biodiversity have been under greater attack than ever. Rapid deforestation is affecting the biotopes of hundreds of species, including the panther chameleon, a species with spectacular intra-specific colour variation. A new study by Michel Milinkovitch, professor of genetics, evolution, and biophysics at the University of Geneva (UNIGE), led in close collaboration with colleagues...

Uncovering the secrets of immune system invaders
The human immune system is a powerful and wonderful creation. If you cut your skin, your body mobilizes a series of different proteins and cells to heal the cut. If you are infected by a virus or bacteria, your immune system responds with a series of cells that attack the invader and neutralize it. But sometimes invaders find ways to exploit the very cells that are designed to protect us. Tuberculosis (Mycobacterium tuberculosis) and its lesser-known (and less virulent) relative Mycobacterium...

Alert to biologists: Ribosomes can translate the 'untranslated region' of messenger RNA
In what appears to be an unexpected challenge to a long-accepted fact of biology, Johns Hopkins researchers say they have found that ribosomes -- the molecular machines in all cells that build proteins -- can sometimes do so even within the so-called untranslated regions of the ribbons of genetic material known as messenger RNA (mRNA). "This is an exciting find that generates a whole new set of questions for researchers," says Rachel Green, Ph.D., a Howard Hughes Medical Institute investigator...

Eukaryotes: A new timetable of evolution
Contaminated samples have evidently created some confusion in the timetable of life. On the basis of ultra-clean analyses, an international team, including scientists from the Max Planck Institute for Biogeochemistry, has disproved supposed evidence that eukaryotes originated 2.5 to 2.8 billion years ago. In contrast to prokaryotes such as bacteria, eukaryotes have a nucleus. Some researchers thought they had discovered molecular remnants of living organisms in rock samples up to 2.8 billion...

New mechanisms of self-organization in living cells
Chromosome is a structure inside the cell nucleus that carries a large part of the genetic information and is responsible for its storage, transfer and implementation. Chromosome is formed from a very long DNA molecule - a double chain of a plurality of genes. Given that the diameter of the cell nucleus is usually around hundredth of a millimeter or even less, while the total length of DNA constituting human genome is about two meters, it is clear that DNA must be packaged very...

Scientists blueprint tiny cellular 'nanomachine'
Scientists have drawn up molecular blueprints of a tiny cellular 'nanomachine', whose evolution is an extraordinary feat of nature, by using one of the brightest X-ray sources on Earth. The scientists produced the structural map of this nanomachine - diacylglycerol kinase - by using a "hit and run" crystallography technique. In doing so, they have been able to understand how the tiny enzyme performs critical cellular duties - answering questions that have been on the table for over 50 years...

Scientists solve mystery behind earthworm digestion
Scientists have discovered how earthworms can digest plant material, such as fallen leaves, that would defeat most other herbivores. Earthworms are responsible for returning the carbon locked inside dead plant material back into the ground. They drag fallen leaves and other plant material down from the surface and eat them, enriching the soil, and they do this in spite of toxic chemicals produced by plants to deter herbivores. The scientists, led by Dr Jake Bundy and Dr Manuel Liebeke from...

A new twist in genetic switches
Rice University researchers have a new twist for those clinging to old ideas about a basic biological process. The Rice lab of theoretical biological physicist Peter Wolynes reported this week that the activity of a master regulator in cells is determined by kinetics, a notion that counters decades-old classical models in molecular biology that attribute the control of genetic processes to the thermodynamics of biochemical reactions. The genetic switch in question relies on a recently...

DNA research offers clues on cell mutation
A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly damaged by things from the outside environment, like sunlight, cigarette smoke and radiation. However, more recently researchers have discovered that sources from within the cell itself can sometimes be even more damaging. DNA, or deoxyribonucleic acid, is found in the...

Structure of a hantavirus protein as a promising model for drug design
Bank voles are small rodents that are not dangerous by themselves, but their excreta can contain one of the dangerous hantaviruses. While bank voles are unaffected by the infection, hantaviruses can cause potentially fatal diseases in humans for which no treatments exist. In central and northern Europe, infection is accompanied by fever, headache, or even renal failure. The strain that occurs in East Asia -- the Hantaan virus -- is even more dangerous: up to five percent of infected patients...

Two new weapons in the battle against bacteria
Proteins are made up of a chain of amino acids and are vital for all cell processes. Proteases are among the most important types of protein. Like "molecular scissors", they cut other proteins at given positions and thereby execute important cell functions. By cutting the amino acid chains to the right length or breaking proteins apart they, for example, activate or deactivate proteins, decompose defective ones or switch signal sequences that serve to transport proteins to their proper position...

Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published in in the early edition of the Proceedings of the National Academy of Sciences the week of May 26 and the May 30 issue of Physical Review Letters. DNA is a long, unwieldy molecule that tends to repel itself because it is negatively charged, yet it can spool tightly. Within the heads of...
