Gene decoding obeys road traffic rules

One of life's most basic processes -- transcription of the genetic code -- resembles road traffic, including traffic jams, accidents and a police force that controls the flow of vehicles. This surprising finding, reported recently by Weizmann Institute researchers in Nature Communications, might facilitate the development of a new generation of drugs for a variety of disorders.

Using gold and light to study molecules in water

Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, as there is currently no reliable way of examining both the behavior and the chemical structure of molecules in a liquid in real time.

Cross-country collaboration leads to new leukemia model

Eight years ago, two former Stanford University postdoctoral fellows, one of them still in California and the other at the Harvard Stem Cell Institute (HSCI) in Cambridge, began exchanging theories about why patients with leukemia stop producing healthy blood cells. What was it, they asked, that caused bone marrow to stop producing normal blood-producing cells?

New protein discovered with vast potential for treatment of cancer and other diseases

In cancer research, discovering a new protein that plays a role in cancer is like finding a key and a treasure map: follow the clues and eventually there could be a big reward. At least that's the hope from a new study published in the journal Nature that discovered a novel protein called ceramide-1 phosphate transport protein (CPTP) -- a finding that could eventually lead to the development of new drugs to treat a variety of cancers and other conditions involving inflammation and thrombosis, or blood clotting.

Study offers promising new direction for organ regeneration and tissue repair

BOSTON – Because most human tissues do not regenerate spontaneously, advances in tissue repair and organ regeneration could benefit many patients with a wide variety of medical conditions.

Now a research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Dana-Farber/Boston Children's Cancer and Blood Disorders Center has identified an entirely new approach to enhance normal tissue growth, a finding that could have widespread therapeutic applications.

Chemical company giants stall with global economy

The world's 50 largest chemical companies — with combined 2012 sales of almost $1 trillion and products that touch the lives of people everywhere — are the topic of the cover story in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

Adjustable injectisome: 3-D molecular syringes

Abdominal pain, fever, diarrhoea -- these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome. For the first time, an international team of researchers including scientists at the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany, has unraveled this molecular syringe's spatial conformation.

The naked mole-rat's secret to staying cancer free

Mice and rats have long since been a standard animal model for cancer research, mainly due to their short lifespan of four years on average and high incidence of cancer. Naked mole rats however, are a mystery among mammals. This social tiny African subterranean rodent has a maximum lifespan exceeding 30 years and most surprisingly, is cancer-resistant. The fact that so far, not a single incident of cancer has been detected makes the naked mole rat a fitting model for finding novel ways to fight cancer.

Insect-inspired super rubber moves toward practical uses in medicine

The remarkable, rubber-like protein that enables dragonflies, grasshoppers and other insects to flap their wings, jump and chirp has major potential uses in medicine, scientists conclude in an article in the journal ACS Macro Letters. It evaluates the latest advances toward using a protein called resilin in nanosprings, biorubbers, biosensors and other applications.

Sensitive parenting can boost premature children's school performance

Sensitive parenting helps protect against the negative effects of being born prematurely on children's school success, a new study has found.

Children born prematurely are at risk of a variety of neurological impairments which can mean they are more likely to need special educational support when they reach school age.

But a new study led by the University of Warwick shows that parents of very preterm and very low birthweight (VP/VLBW) children can increase their child's academic achievement through sensitive and cognitively stimulating parenting.

Progress in using ethanol to make key raw material now produced from oil

Ethanol from corn and other plants could become the sustainable, raw material for a huge variety of products, from plastic packaging to detergents to synthetic rubber, that are currently petroleum-based. This was the conclusion of an article published in the ACS journal Industrial & Engineering Chemistry Research.

Chemists develop innovative nano-sensors for multiple proteins

Chemists at Johannes Gutenberg University Mainz (JGU) have developed a new method for parallel protein analysis that is, in principle, capable of identifying hundreds or even thousands of different proteins. It could be used to detect the presence of viruses and identify their type in tiny samples. At the same time, it is very cost-effective and quick. "We see possible applications of this technique in medicine, where it could be used, for example, for the rapid diagnosis of a wide range of diseases.

Another scientific proof of the difference in social perception between men and women

"The Love Hormone", Oxytocin affects men and women differently in social contexts- in men it improves the ability to identify competitive relationships whereas in women it facilitates the ability to identify kinship. "These findings are in agreement with previous studies on the social differences between the sexes: women tend to be more communal and familial in their behavior, whereas men are more inclined to be competitive and striving to improve their social status", said Prof. Simone Shamay-Tsoory from the Dept. of Psychology at the University of Haifa who led the research.

1 size doesn't fit all

One size chart doesn't fit all when it comes to evaluating birth weight and health outcomes of newborns.

A new study, recently published online by the American Journal of Obstetrics and Gynecology, shows ethnicity-specific birth weight charts are better at identifying newborns who are small for gestational age (SGA), a classification associated with hypothermia, hypoglycemia, infection and admission to the neonatal intensive care unit.

Hide, ambush, kill, eat: The giant water bug Lethocerus patruelis kills a fish

During their study of the giant water bug N. Simov and M. Langourov from the study team had the unique chance to witness and record on video the vicious predatory practices of the species. In the recorded material, a larva uses the stems of a water plant to stalk and ambush its unsuspicious pray. The giant water bug larva can be seen storming from its cover and catching and injecting saliva into a small fish.
