Unique field study shows that pesticide harms wild bees

Neonicotinoids are used for seed dressing of rapeseed, to protect the young plants against flea beetles. Since 2013, use of this type of pesticide has been restricted by the EU...

To predict disease researchers ask if plant neighbors are relatives

This image shows a tropical forest tree canopy, Barro Colorado island, Panama. High biodiversity tropical forest may be the result of a struggle between plants, the diseases that infect them, and the insects and animals that eat them. Parker et al., by proposing that the degree of genetic relationship between plant community members affects the outcome of disease outbreaks, come one step closer to a model that predicts disease outcomes.Disease is an invisible hand, shaping plant communities across the globe and determining the outcomes of environmental change, weed invasions and agriculture and forestry management strategies. Whether or not a...

Testosterone key to new bird bang theory

Wake Forest University biologist Matthew Fuxjager studies golden-collared manakins.New research from a Wake Forest University biologist who studies animal behavior suggests that evolution is hard at work when it comes to the acrobatic courtship dances of a tropical...

Vampire squid discovery shows how little we know of the deep sea

Among soft-bodied cephalopods, vampire squid live life at a slower pace. At ocean depths from 500 to 3,000 meters, they don't swim so much as float, and they get by...

Clemson, international team crack genetic code of Upland cotton

In a groundbreaking achievement led by an international team that includes Clemson scientist Chris Saski, the intricately woven genetic makeup of Upland cotton has been decoded for the first time...

Video: Octopuses have unique way to control their 'odd' forms

The body plan of octopuses is nothing if not unique, with a sophisticated brain in a soft, bilaterally symmetrical body, encircled by eight radially symmetrical and incredibly flexible arms. Now,...

Flourishing faster: How to make trees grow bigger and quicker

Poplar trees were modified to grow quicker and faster by Professor Simon Turner at The University of Manchester.Scientists at The University of Manchester have discovered a way to make trees grow bigger and faster, which could increase supplies of renewable resources and help trees cope with the...

Discovery of new plant switch could boost crops, biofuel production

Deserah Strand, with a team of Michigan State University researchers, has discovered a switch that regulates plant photosynthesis -- the process that lets plants store solar energy and use it to grow and produce food.A team of Michigan State University researchers has discovered a switch that regulates plant photosynthesis -- the process that lets plants store solar energy and use it to grow and...

Logging means ants, worms and other invertebrates lose rainforest dominance

Carnivorous ants help keep herbivorous invertebrate numbers down.Invertebrates perform essential functions for the smooth running of the ecosystems in tropical forests. For example, creatures such as termites and millipedes help dead leaves decompose and release their nutrients...

Ocean myth busted: 'Toddler' sea turtles are very active swimmers

One of the 44 sea turtles tagged in this study was this green turtle yearling.It turns out sea turtles, even at a tender 6-18 months of age, are very active swimmers. They don't just passively drift in ocean currents as researchers once thought. NOAA...

Diabetes drug found in freshwater is a potential cause of intersex fish

Rebecca Klaper studies emerging contaminants in freshwater systems, including the residuals of pharmaceuticals in wastewater.A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish -male fish that produce eggs.

Twins experiment reveals genetic link with mosquito bites

Identical twins place their hands in a Y-shaped tube filled with mosquitoes to see how attractive they smell.The likelihood of being bitten by mosquitoes could be down to our genes, according to a study carried out on twins.

UNH researchers discover new method to detect most common bacteria contaminating oysters

In New Hampshire's Great Bay, a team of UNH undergraduate and graduate students collect oysters to look at environmental conditions that might favor <i>V. parahaemolyticus</i>.In a major breakthrough in shellfish management and disease prevention, researchers at the University of New Hampshire have discovered a new method to detect a bacterium that has contaminated New...

Engineering the P450 enzyme to perform new reactions

Engineered cytochrome P450 enzymes can perform chemical reactions valuable to the pharmaceutical community.Enzymes, the micro machines in our cells, can evolve to perform new tasks when confronted with novel situations. But what if you want an enzyme to do an entirely different...

Big butts aren't everything to male baboons

Noodle, a female baboon from Kenya, reveals her bright red swollen bottom -- a sign that her time of ovulation is near. Researchers have long thought that baboon males prefer females with bigger backsides as the mark of a good mother, but a new study suggests that the size of a female's swollen rump doesn't matter as much as previously thought.While the female baboon's big red bottom may be an eyesore to some, it has an aphrodisiac effect on her mates. Biologists have long thought that baboon males prefer females...

Telling the time of day by color

Research by scientists at The University of Manchester has revealed that the colour of light has a major impact on how the brain clock measures time of day and on...

New transitional stem cells discovered

Pre-eclampsia is a disease that affects 5 to 8 percent of pregnancies in America. Complications from this disease can lead to emergency cesarean sections early in pregnancies to save the...

Longest mammal migration raises questions about distinct species

Western gray whales are shown.A team of scientists from the United States and Russia has documented the longest migration of a mammal ever recorded -- a round-trip trek of nearly 14,000 miles by a...

How a bacterial cell recognizes its own DNA

This image shows (l-r) staff scientists Dr. Gil Amitai and Prof. Rotem Sorek.It may come as a bit of a surprise to learn that bacteria have an immune system -- in their case to fight off invasive viruses called phages. And like...

MIPT researchers grow cardiac tissue on 'spider silk' substrate

These are heart tissue cells grown on a matrix, stained with fluorescent markers.Genetically engineered fibers of the protein spidroin, which is the construction material for spider webs, has proven to be a perfect substrate for cultivating heart tissue cells, MIPT researchers found....

First report of a new crop virus in North America

This is Bright Agindotan, Research Assistant Professor at Montana State University, former postdoctoral researcher at the Energy Biosciences Institute.The switchgrass exhibited mosaic symptoms--splotchy, discolored leaves--characteristic of a viral infection, yet tested negative for known infections. Deep sequencing, a new technology, revealed the plants were infected with a new...
