Fathering offspring is more than just a race to the egg
The chance of a male fathering offspring may not be a simple race to the egg, but is influenced by the length of the male's sperm, say scientists from the University of Sheffield.
Sex? It all started 385 million years ago (w/ Video)
It may not have been love as we know it, but around 385 million years ago, our very distant ancestors—armoured fish called placoderms—developed the art of intercourse.
Smart farming the key to China's food problems, study says
Clever farming techniques would provide China with more than enough grain to feed its escalating population in the coming decades while easing stress on its environment, scientists reported on Wednesday.
Reconstructing the life history of a single cell
Researchers have developed new methods to trace the life history of individual cells back to their origins in the fertilised egg. By looking at the copy of the human genome present in healthy cells, they were able to build ...
Personality determines whether tarantulas copulate with males or cannibalize them
Sexual cannibalism in spiders – the attack and consumption of males by females before or after copulation – is very widespread. A new investigation analyses the reason behind such extreme behaviour, at ...
Legume research uncovers nitrogen uptake genes
(Phys.org) —Increased nitrogen-use efficiency of plants and an associated reduced need for nitrogen-based fertilisers may be a step closer following University of Adelaide research on legumes.
An ancient 'Great Leap Forward' for life in the open ocean
It has long been believed that the appearance of complex multicellular life towards the end of the Precambrian (the geologic interval lasting up until 541 million years ago) was facilitated by an increase in oxygen, as revealed ...
Bacteria to aid sutainable sugarcane production
Scientists have discovered a bacterium that could reduce the use of fertiliser in sugarcane production and improve yield.
Females fight back in sperm wars
(Phys.org) —Females exposed to a risk of sperm competition have been found to produce more defensive ova compared to the eggs of females reared under no risk of sperm competition, according to researchers ...
Promiscuity and sperm selection improves genetic quality in birds
New research from the University of East Anglia has shown that females can maximise the genetic quality of their offspring by being promiscuous.
World changing technology enables crops to take nitrogen from the air
A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.
Gene breakthrough could boost rice yields by 20 percent
Scientists on Wednesday said they had developed a strain of rice that grows well in soils lacking the nutrient phosphorus, a feat that could boost crop yields for some farmers by as much as a fifth.
Plant perfumes woo beneficial bugs
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered that maize crops emit chemical signals which attract growth-promoting microbes to live amongst their roots. This is the ...
Early ripening of grapes pinned to warming, soil moisture
Researchers in Australia say they have pinpointed key factors in the early ripening of grapes, providing potential answers for wine growers threatened by global warming.
