Understanding how brain makes sense sound
2019/11/22
For neuroscientists, human hearing is a process full of unanswered questions. How does the brain translate sounds -- vibrations that travel through the air -- into the patterns of neural activity that...
Batlab studies echolocation to learn how animals "see" with sound（图）
Batlab echolocation animals see sound
2017/11/23
Neuroscientist Cindy Moss is investigating how animals use sensory information to guide their behavior. Her team at Johns Hopkins University's "Batlab" is currently focused on bat echolocation -- high...

Stress Detection and Classification of Laying Hens by Sound Analysis
Laying Hens Stress Recognition Sound Analysis Monitoring System
2016/5/18
Stress adversely affects the wellbeing of commercial chickens, and comes with an economic cost to the industry that cannot be ignored. In this paper, we first develop an inexpensive and non-invasive, ...
In the March 23 issue of the journal Nature Materials, they describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
