Color-changing fluorescent dyes allow for accurate temperature measurements within living cells
A novel single fluorophore ratiometric fluorotherm developed using solvent-dyed dyes achieved record sensitivity and enabled live cells and environmental sensing. Credit: Science Tokyo Temperature is an important variable that affects countless biological processes at the cellular level. However, accurate measurement of temperature within living cells remains difficult. Traditional temperature measurement techniques often lack the spatial resolution required to detect subtle…

Rat! Because scientists say that the temperature means more rats, more rodents are invading the city.
Rats will leave the burrow in a park in New York on September 17, 2015. Credit: AP Photo/Mary Altfer, File The invasion of rats in many world cities seems to be soaring, especially in Washington. New research has blamed the temperature, urbanization of global warming, and other human behavior. In the first survey of rat groups and reasons that are…

Iron melting temperature and phase stability under nuclear-like conditions shed light on Earth’s geodynamics
Laser-driven impact phenomena in iron at high-power laser facilities (HPLF). X-ray absorption spectroscopy (XAS) was used to determine the melting temperature and microstructure of iron at pressures relevant to geosciences. Credit: Jean-Alexis Hernandez, European Synchrotron Radiation Facility. Iron is one of the major elements found in the Earth’s inner core, which is characterized by extremely high temperatures and pressures. Therefore,…

New process produces ordered semiconductor material at room temperature
Graphical summary. Credit: Nature Synthesis (2025). DOI: 10.1038/s44160-024-00717-z Scientists at the University of Twente have developed a method to create highly ordered semiconductor materials at room temperature. The UT study was published today in the journal Nature Synthesis. This breakthrough could improve the efficiency of optoelectronics by controlling the crystal structure and reducing the number of defects at the nanoscale.…

Solar wind power likely controls Uranus’ thermosphere temperature
Uranus captured by Webb’s near-infrared camera. Credit: NASA, ESA, CSA, STScI Uranus’ upper atmosphere has been cooling for decades, and now scientists have discovered why. Observations from Earth show that Uranus’ upper atmosphere has been cooling for decades, but there is no clear explanation. Now, a team led by scientists from Imperial College London has determined that unpredictable long-term changes…

Cooling: Slowing ocean circulation could limit Arctic temperature rise
A map depicting the direction in which the AMOC transports warm water from the tropics to high latitudes. Credit: R. Currie, Woods Hole Oceanographic Institution/Science/USGCRP The Arctic is warming three to four times faster than the global average. But new research suggests that slowing major ocean currents could reduce projected Arctic warming by up to 2C by the end of…
