New research reveals which genes are needed to reinstate the rich, original flavor of tomatoes, now absent in many grocery shelf varieties of this fruit. The results are published in the 27 January issue of Science.
Scientists discover key mechanism that controls when fruit flies sexually mature
Like humans, insects go through puberty. The process is known as metamorphosis. Examples include caterpillars turning into butterflies and maggots turning into flies.
But, it has been a long-standing mystery as to what internal mechanisms control how insects go through metamorphosis and why it is irreversible.
New remote sensing maps of the forest canopy in Peru test the strength of current forest protections and identify new regions for conservation effort, according to a report led by Carnegie’s Greg Asner published in Science.
Asner and his Carnegie Airborne Observatory team used their signature technique, called airborne laser-guided imaging spectroscopy, to identify preservation targets by undertaking a new approach to study global ecology—one that links a forest’s variety of species to the strategies for survival and growth employed by canopy trees and other plants. Or, to put it in scientist-speak, their approach connects biodiversity and functional diversity.
It’s that dreaded time of year – flu season. And we humans aren’t the only ones feeling the pain. Dogs can get the flu, too.
Scientists at the University of Rochester School of Medicine and Dentistry have developed, for the first time, two new vaccines for canine influenza. This research is not only important for improving the health of our furry friends, but for keeping us safe, too. Dogs that have been infected with multiple influenza viruses have the potential to act as “mixing vessels” and generate new flu strains that could infect people. This hasn’t happened yet, but experts say it’s possible.
Nearly a century after it was theorized, Harvard scientists have succeeded in creating the rarest - and potentially one of the most valuable - materials on the planet.
This week the UK Government published its long awaited industrial strategy, marking a distinctive break from the previous Conservative regime. Gone is David Cameron's more laissez faire attitude to managing the economy. In its place is a more proactive approach, which seeks to stimulate industry with targeted investment. Taking advantage of the greater flexibility afforded by freedom from the EU's state aid rules the plan sees some exciting developments in the decarbonisation of the UK economy.

As is well-known, space flights bring with them a unique set of health hazards. That includes bone and muscle deterioration. Loss of bone density is currently one of the most serious problems for astronauts. It is similar in nature to osteoporosis, an ailment common for senior people. Understanding microgravity and its effects on living organisms can help find new clinical methods of coping with this issue.
Pollution from the controlled fires that burn across Brazil's São Paulo state during the sugarcane-harvesting season has a negative impact on infant health nearby. But the health of those same infants likely benefits from the economic opportunities the fires bring to their parents.
Researchers at Princeton and Duke universities gathered information from satellites, pollution monitors and birth records to untangle those competing influences and accurately measure the impact of pollution from the fires. They found that exposure to pollution from the fires in the last few months of gestation leads to earlier birth and smaller babies, and they found some evidence of increased fetal mortality. Conditions in early life, including in utero, have been shown to affect children's long-term outcomes, not only in terms of health but also their educational and economic success.
Floating wetlands may seem odd but are perfectly natural. They occur when mats of vegetation break free from the shore of a body of water. That got ecological engineers curious about how they affect the water they bob up and down in.
A group from Saint Francis University in Pennsylvania and the University of Oklahoma, including researcher William Strosnider, has found that the floating wetlands show promise for water treatment. They engineered four different floating treatment wetlands designs using different materials and wetland plants.
Changes in rainfall and temperature are predicted to transform wetlands in the Gulf of Mexico and around the world within the century, a new study from the USGS and the University of Texas Rio Grande Valley concludes.
Sea-level rise isn’t the only aspect of climate change expected to affect coastal wetlands: changes in rainfall and temperature are predicted to transform wetlands in the Gulf of Mexico and around the world within the century. These changes will take place regardless of sea-level rise, a new study from the US Geological Survey and the University of Texas Rio Grande Valley concludes.
