TRACKSIDE INTERVIEWS (Conducted by Davide Valsecchi)Q: Incredibly exciting qualifying. How was that for you Lewis?Lewis HAMILTON: I made a mistake in the last corner. A lot of pressure because we have been struggling to get temperature in these tyres, we don’t know if it’s a one-lap tyre, so it was all or nothing. But the lap just got better and better throughout. I saw Valtteri ...

Extremely high temperatures in the US southwest have sent the mercury above 115F (46C), but duty still calls for the Phoenix Fire Department.


Plants sacrifice 'daughters' to survive chilly weather

Plants adopt different strategies to survive the changing temperatures of their natural environments. This is most evident in temperate regions where forest trees shed their leaves to conserve energy during the cold season. In a new study, a team of plant biologists found that some plants may selectively kill part of their roots to survive under cold weather conditions.

Scientists demonstrate adaptation of animal vision in extreme environments

Animals can adapt their ability to see even with extreme changes in temperature, researchers have discovered. The researchers looked deeply into the eyes of catfish living in cold-water streams at altitudes of up to nearly 3 km in the Andes Mountains, and found the protein known as rhodopsin that enables vision in dim light also accelerates the speed at which vision occurs as temperatures drop.

Much cooler air with temperatures more typical of mid- to late September will sweep across the Great Lakes and Northeast this weekend into next week.


| From heatwaves to hurricanes, floods to famine: seven climate change hotspots

Global warming will not affect everyone equally. Here we look at seven key regions to see how each is tackling the consequences of climate change
It could have been the edge of the Sahara or even Death Valley, but it was the remains of a large orchard in the hills above the city of in southern Spain last year. The soil had broken down into fine white, lifeless sand, and a landscape of rock and dying orange and lemon trees stretched into the distance.
A long drought, the second in a few years, had devastated the harvest after city authorities had and farmers were protesting in the street. It was a foretaste of what may happen if temperatures in the Mediterranean basin continue to rise and desertification grows.

Unseasonably warm temperatures followed by freezing temperatures in mid-March have led to a reportedly 50 percent increase in prices


Quantum and isotope effects in lithium metal

Added: 22.06.2017 20:55 | 1 views | 0 comments

The crystal structure of elements at zero pressure and temperature is the most fundamental information in condensed matter physics. For decades it has been believed that lithium, the simplest metallic element, has a complicated ground-state crystal structure. Using synchrotron x-ray diffraction in diamond anvil cells and multiscale simulations with density functional theory and molecular dynamics, we show that the previously accepted martensitic ground state is metastable. The actual ground state is face-centered cubic (fcc). We find that isotopes of lithium, under similar thermal paths, exhibit a considerable difference in martensitic transition temperature. Lithium exhibits nuclear quantum mechanical effects, serving as a metallic intermediate between helium, with its quantum effect-dominated structures, and the higher-mass elements. By disentangling the quantum kinetic complexities, we prove that fcc lithium is the ground state, and we synthesize it by decompression.


Quantum correlations from a room-temperature optomechanical cavity

The act of position measurement alters the motion of an object being measured. This quantum measurement backaction is typically much smaller than the thermal motion of a room-temperature object and thus difficult to observe. By shining laser light through a nanomechanical beam, we measure the beam’s thermally driven vibrations and perturb its motion with optical force fluctuations at a level dictated by the Heisenberg measurement-disturbance uncertainty relation. We demonstrate a cross-correlation technique to distinguish optically driven motion from thermally driven motion, observing this quantum backaction signature up to room temperature. We use the scale of the quantum correlations, which is determined by fundamental constants, to gauge the size of thermal motion, demonstrating a path toward absolute thermometry with quantum mechanically calibrated ticks.
