Boom, el avión que hará Londres-Nueva York en 3 horas y media
Ya se está construyendo el prototipo del sucesor del Concorde, un avión que será capaz de llegar a Londres, desde Nueva York, en poco más de 3 horas, según comentan los responsables por el proyecto en boom.aero. Creado en Denver, Boom es el resultado de combinar motores potentes con fibra de carbono y software avanzado
Many species now going extinct may vanish without a fossil trace
Latest Science News -- ScienceDaily - Hace 13 horas
Scientists struggle to compare the magnitude of Earth's ongoing sixth mass-extinction event with the five great die-offs of prehistory. A new study by three paleontologists shows that the species now perishing may vanish without a permanent trace -- and earlier extinctions may be underestimated as well.
US adults get failing grade in healthy lifestyle behavior

Only 2.7 percent of the US adult population achieves all four of some basic behavioral characteristics that researchers say would constitute a 'healthy lifestyle' and help protect against cardiovascular disease, a recent study concluded.
Plants boost extreme temperatures by 5°C
Latest Science News -- ScienceDaily - Hace 13 horas
Heatwaves from Europe to China are likely to be more intense and result in maximum temperatures that are 3 degrees Celsius to 5 degrees Celsius warmer than previously estimated by the middle of the century -- all because of the way plants on the ground respond to carbon dioxide in the atmosphere.
Scientists say many plants don't respond to warming as thought
Latest Science News -- ScienceDaily - Hace 13 horas
A global study suggests that increases in plant respiration that could occur under global warming might not be as big as previously estimated, especially in the coldest regions. Since respiration adds CO2 to the air, it means that changes in plants might not add to the already growing burden as much as feared.

Astrophysicists catch two supernovae at the moment of explosion
Latest Science News -- ScienceDaily - Hace 14 horas
Two supernovae have been caught in the act of exploding by an international team of astrophysicists. Stars 10 to 20 times the mass of our sun often puff up to supergiants before ending their lives as supernovae. These stars are so large that Earth's orbit would easily fit inside such a star.

The important role of specialist bacteria has been uncovered in the formation and movement of platinum and related metals in surface environments.
Tracing the scent of fear
Latest Science News -- ScienceDaily - Hace 14 horas
A new study has identified nerve cells and a region of the brain behind this innate fear response. With a new technique that uses specially-engineered viruses to uncover the nerve pathway involved, a research team has pinpointed a tiny area of the mouse brain responsible for this scent-induced reaction.

Polymer scientists identify for the first time the factors that govern the final morphology of self-assembling chiral filament bundles. They also report experimental results supporting their new model.
Recycling pecan wood for commercial growing substrates
Latest Science News -- ScienceDaily - Hace 14 horas
A study evaluated vegetative growth and leaf nutrient responses of chrysanthemum grown in five pecan wood chip substrate levels that substituted 0%, 25%, 50%, 75%, and 100% of peatmoss by volume. Three water-soluble fertilizer rates were applied. Results showed that, with low to moderate amounts of pecan wood, further adjustments to fertilizer rate and irrigation volume would support sustainable fertigation practices, reduce dependence on peatmoss, and provide a value-added recycling option for pecan growers.
