Hawaii longline fishermen allowed to resume catching tuna

In this May 12, 2009, file photo, bigeye tuna line the floor of the United Fishing Agency’s auction house in Honolulu. Federal regulators are allowing Hawaii fishermen to resume catching a prized tuna species in their most productive fishing grounds west of the islands, more than two months after the fishery was closed in early […]

A rolling stone gathers no mates

A rolling stone gathers no mates

Researchers have shown that when animals disperse freely through contiguous habitats, mate choice alone can lead to habitat fragmentation and isolated populations if females avoided mating with dispersers.

Diagnostic tools using synthetic biology

Diagnostic tools using synthetic biology

(Phys.org)—Synthetic biology is a multi-disciplinary field that applies engineering techniques to biological systems. While the foundations of synthetic biology were laid in the 1990s with the burgeoning of genomics and automated sequencing, synthetic biology as a discipline, emerged in the early 2000s with the development of simple gene regulatory circuits. Since then, the field has […]

Dicamba drift affects non-target plants and pollinators

Dicamba drift affects non-target plants and pollinators

The scientists found that application of dicamba inhibited or delayed flowering in common boneset (Eupatorium perfoliatum), resulting in significantly reduced visitation by insect species, including honeybees (pollinators) and syrphid flies (natural enemies). The image shows a damaged E. perfoliatum plant that received a rate of 56 grams of dicamba per hectare.s Credit: Penn State Dicamba […]

Five reasons we should embrace gene-editing research on human embryos

Five reasons we should embrace gene-editing research on human embryos

Future people would be grateful if their disease is cured, rather than being replaced by a different healthier or non-disabled person. sabianmaggy/Flickr, CC BY-SA Scientists from around the world are meeting in Washington this week to debate how best to proceed with research into gene-editing technology. Gene editing is a new precise form of genetic […]

Female frogs identify own offspring using inner GPS

Female frogs identify own offspring using inner GPS

In the brilliant-thighed poisonfrog, the males transport the tadpoles to nearby water bodies.

According to a study conducted by Vetmeduni Vienna, male and female frogs have different strategies for offspring discrimination. Females remember the […]

Mexico has been a mecca for naturalists, and its […]

Researchers cultivate the majority of bacteria in the laboratory that colonize Arabidopsis plants in nature

Researchers cultivate the majority of bacteria in the laboratory that colonize Arabidopsis plants in nature

Arabidopsis thaliana. Credit: Wikipedia. No organism is an island — a fact that also applies to plants. Healthy plants host complex microbial communities comprising over 100 bacterial species which presumably play important roles in plant growth and health. Plants allow access only to a select community of bacteria, designated the plant microbiota, that originate mainly […]
