Research lab
Japanese national university based in Sendai, known for research spanning materials science, geophysics, neuroscience, and planetary science.
Tohoku University researchers found that adding wastewater DNA from sulfate-reducing bacteria improved a model's flagging of severely corroded sewer pipes. They say the resulting maps could help cities choose which pipes to inspect first.
Reality
Tohoku University researchers formed crystalline beta-SiC at 800 degrees Celsius by soaking Mn5SiC in molten bismuth. The step also left an interconnected network of nanoscale plates, in a ceramic that usually needs much hotter processing.
Reality
UCL and Tohoku researchers scanned 67 Japanese learners of English and found finer auditory precision went with less left sensorimotor activity on vowels. The lead author takes that to mean sharper listeners analyze a new vowel as acoustics first, an interpretation the authors call exploratory.

Tohoku University researchers found that stimulating the vagus nerve after each practice session gave mice stronger eye-movement learning on later days. The study adds brain blood vessels to the routes by which the stimulation might act, though so far that link rests only on a correlation.
Reality
Japanese chemists say lattice spacing, with cutoffs at 14.62 and 14.72 angstroms, sorts gold-alloy magnetism better than electron count. That gives chemists looking for new magnetic quasicrystals one measurable target, as long as a new alloy's spacing can be predicted from its composition.
Reality
Tohoku University researchers and colleagues modelled early Mars's formaldehyde rain, putting about 10 times the global average on Tharsis and Elysium. The prediction links where a raw material for sugars and amino acids landed to the planet's ancient water cycle.
Reality
Tohoku and Meijo researchers report a 110% rise in flood-exposed settlement area in Japan's Marumori and blame misplaced trust in levees. Their Meiji-era terrain model shows what levees do to floodwater more firmly than it shows why people built near them.
Reality
Tohoku University researchers imaging mice saw brain blood volume start rising about 50 seconds before REM sleep, yet neuronal ATP fell once REM began. The team takes this to mean dreaming uses energy faster than it arrives, though slower ATP production would look the same.
Reality
Researchers at Tohoku University grew spinel iron oxide nanoparticles from iron powder and water under ultrasound alone. The most informative comparison in the paper is the control run without ultrasound.
Reality
A Tohoku University-led team used the XRISM satellite to read iron emission lines around the quasar H1821+643, and measured turbulent hot gas spanning about 300,000 light-years with roughly 100 times the energy earlier estimates allowed.
Reality
Kyocera and Tohoku University report 13.6 decibels of isolation on a silicon waveguide, roughly a 95 percent cut in reflected light, from garnet crystallised by a laser aimed at one small patch. Lower loss and mass production are still on their list.
Reality
Conventional X-ray cannot always resolve what sits beneath a multilayer device, so Rigaku and Tohoku have opened an institute in Sendai where the first three years go to soft X-ray methods and to the people who read the data.
Reality
A Tohoku and Queen Mary team ran acetylene over cerium oxide and grew graphene-based carbon at 300C, where the catalyst's own oxygen loss does the work and the furnace setpoint decides which of three materials comes out.
