Japan scientists find ageing cure - for flowers
Japanese scientists say they have found a way to slow down the ageing process in flowers by up to a half, meaning bouquets could remain fresh for much longer.
Gene discovered that activates stem cells for organ regeneration in Planarians
Researchers announced the discovery of a gene zic-1 that enables stem cells to regrow a head after decapitation in flatworm planarians. Professor Christian Petersen and Ph.D. student Constanza Vásquez-Doorman ...
Flower's bellows organ blasts pollen at bird pollinators
A small tree or shrub found in mountainous Central and South American rainforests has a most unusual relationship with the birds that pollinate its flowers, according to a study reported in the journal Current Bi ...
With 'biological sunscreen,' mantis shrimp see the reef in a whole different light
In an unexpected discovery, researchers have found that the complex eyes of mantis shrimp are equipped with optics that generate ultraviolet (UV) color vision. Mantis shrimp's six UV photoreceptors pick up ...
Unexpected stability and complexity in transcriptional enhancers' interactions
Contrary to what was thought, sequences of DNA called enhancers – which control a gene's output – find their targets long before they are activated during embryonic development, scientists at the European Molecular Biology ...
Engineering light-controlled proteins
(Phys.org) —A University of Wyoming professor has engineered proteins that can be activated by near-infrared light as a way to control biological activities in deep tissues of small mammals.
'Bone-house wasp' uses dead ants to protect their nest
A new species of spider wasp, the 'Bone-house Wasp,' may use chemical cues from dead ants as a nest protection strategy, according to a recent study published July 2, 2014 in the open-access journal PLOS ON ...
First national model for Bovine TB calls for more focus on cattle
In a study published in Nature this week, a team of researchers based at the University of Warwick has produced the first national model to investigate the bovine TB spread.
Boron tolerance discovery for higher wheat yields
Australian scientists have identified the genes in wheat that control tolerance to a significant yield-limiting soil condition found around the globe – boron toxicity.
Genetically driven gut feelings help female flies choose a mate
Even among flies, mating is a complicated ritual. Their elaborate courtship dance combines multiple motor skills with advanced sensory cues. Remarkably this behavior is entirely innate. Now, researchers at Rockefeller University ...
Fruit fly research may reveal what happens in female brains during courtship and mating
What are the complex processes in the brain involved with choosing a mate, and are these processes different in females versus males? It's difficult to study such questions in people, but researchers are ...
Nature journal retracts 'game-changer' stem-cell study (Update)
Leading science journal Nature said on Wednesday it had withdrawn a flawed stem-cell study hailed when it was published in January as a "game-changer" in the quest to grow transplant tissue.
New research sheds light on the genetic secrets of deadly algae
(Phys.org) —University of Technology, Sydney research into the genetic makeup of often harmful algae is increasing our understanding of how marine biotoxins can damage global seafood industries and human ...
A sheep's early life experiences can shape behavior in later life
New research has found that a sheep's experiences soon after birth can shape its later behaviour and also that of its offspring.
