New crystal structures reveal mysterious mechanism of gene regulation by the 'magic spot'

Using an innovative crystallization technique for studying three-dimensional structures of gene transcription machinery, an international team of researchers, led by scientists at Penn State, has revealed new insights into the long debated...Show More Summary

Few Chicagoland wetlands left without non-native species, study finds

The wetlands in and around Chicago are overwhelmingly invaded by non-native plants, according to a new study by University of Illinois researchers. The study, which pulls together species occurrence data from over 2,000 wetlands in the urban region, is the first to describe wetland invasion patterns on such a large scale in the Chicagoland area.

Researchers track commercial fishing worldwide in near real-time

The global fishing fleet is so big it can be seen from space. Really.

Toenail fungus gives up sex to infect human hosts

The fungus that causes athlete's foot and other skin and toenail infections may have lost its ability to sexually reproduce as it adapted to grow on its human hosts.

Study suggests evolutionary change in protein function respects biophysical principles

Some molecular biologists who study the proteins that regulate cell operations, including Elizabeth Vierling at the University of Massachusetts Amherst, do not confine their research to understanding the molecules' current roles. They...Show More Summary

Loops, loops, and more loops: This is how your DNA gets organised

Remarkably, living cells are able to package a jumble of DNA over two meters in length into tidy, tiny chromosomes while preparing for cell division. However, scientists have been puzzled for decades about how the process works. Researchers...Show More Summary

Modification of CRISPR guide RNA structure prevents immune response in target cells

CRISPR-mediated genome editing has become a powerful tool for modeling of disease in various organisms and is being developed for clinical applications. Preassembled Cas9 ribonucleoproteins (RNPs) composed of the recombinant Cas9 protein...Show More Summary

Novel technology could allow researchers to develop and test new antimalaria drugs

One of the biggest obstacles to eradicating malaria is a dormant form of the parasite that lurks in the livers of some patients. This dormant form is resistant to most antimalarial drugs and can reawaken months or years later, causing disease relapse.

How bats carry viruses without getting sick

Bats are known to harbor highly pathogenic viruses like Ebola, Marburg, Hendra, Nipah, and SARS-CoV, and yet they do not show clinical signs of disease. In a paper published in the journal Cell Host & Microbe on February 22, scientists...Show More Summary

Synchronised waves control embryonic patterning

During an embryo's journey from a single cell to a complex organism, countless patterning processes make sure that the right cells develop in exactly the right location and at the right time. Cells activate specific genes in a rhythmic manner during this early development, resulting in waves of activation sweeping through the embryo. Show More Summary

Damage encourages maple species to become female, study finds

A few years ago, Rutgers researcher Jennifer Blake-Mahmud was working on a botany project in Virginia when colleagues pointed out a striped maple, a common tree in the understory of mountain forests from Nova Scotia to Georgia.

How changes in biotic interactions impact dryland ecosystems

The negative impact of a lack of plant functional diversity on ecosystems is well-documented, and can be seen in action in most dryland ecosystems. However, the indirect effects of biotic interactions – activities of certain living organisms that can impact the survival of others – are still unknown. The DRYFUN project set out to lift the veil on this issue.

How a zebrafish's squiggly cartilage transforms into a strong spine

In the womb, our strong spines start as nothing more than a rope of rubbery tissue. As our bodies develop, this flexible cord, called the notochord, morphs into a column of bone and cartilage sturdy enough to hold up our heavy upper bodies.

The battle for spinach: Tiny crop, huge value, no virgin soil, big trouble

In the Pacific Northwest, spinach seed is a tiny crop with huge value. And it's in big trouble.

Your drive to the shops makes life pretty noisy for whales

As unlikely as it may seem, your drive to the supermarket is responsible for a lot of noise pollution in our oceans – and a lot of stress to marine life as a result.

Researchers develop process producing cell-sized lipid vesicles for cell-cell synaptic therapies

A team of researchers at the University of California in Irvine, California has demonstrated a novel process to produce cell-sized lipid vesicles (CLVs) from microfluidically generated double emulsion templates by investigating the interfacial...Show More Summary

Changing enzymes for clean energy and disease prevention

?-glycosidases are enzymes that play many roles in nature. They can play a role in metabolic disorders and can break down tough plant fibers. Fredj Ben Bdira changed these enzymes in order to enhance the production of clean energy and to improve the treatment of patients with metabolic diseases.

New weakness discovered in sleeping sickness pathogen

Trypanosomes are single-celled parasites that cause diseases such as human African sleeping sickness and Nagana in animals. But they are also used in basic research as a model system to study fundamental biological questions. Researchers...Show More Summary

Explaining coprophagy – why do dogs eat their own poo?

Dogs are scavengers. As many dog owners know to their cost, dogs often have a penchant for things that we find less than palatable. If it's not counter or table surfing, it might be raiding the kitchen rubbish bin or snacking on rich pickings from the park, street or elsewhere.
