The team also found that this layout in the nose aligns with corresponding maps in the olfactory bulb of the brain. This connection offers new clues about how scent signals travel from the nose into the brain.
The findings were published April 28 in Cell.
Scientists have long known how sensory receptors are arranged in the eyes, ears, and skin, and how those arrangements connect to the brain. Smell has been the exception.

Why does an ant, with a brain smaller than a grain of sand, find the shortest path better than a human engineer?
Richard Feynman didn’t learn about ants from a textbook. He learned by sitting on his bathroom floor with a sugar cube and a stopwatch. What he discovered wasn’t just biology—it was a biological supercomputer solving the \.
New multiplexed imaging technology using standard clinical MRI systems can simultaneously map more than 20 biomarkers in high resolution, providing a comprehensive view of the brain with a single scan.
Researchers at the University of Illinois Urbana-Champaign demonstrated the multiplexed MRI technology (MRx) by characterizing brain tumors and multiple sclerosis lesions—revealing different structural, physiological and molecular changes within the diseases. Led by Zhi-Pei Liang, a professor of electrical and computer engineering and a member of the Beckman Institute for Advanced Science and Technology at the U. of I., the team has reported its findings in the journal Nature.
“MRx can be a powerful tool for noninvasive tissue characterization, helping to advance personalized, precision and predictive medicine,” Liang said. “By providing rich, multidimensional biomarkers to capture disease progression and treatment response, this capability could open new opportunities for more precise diagnosis, individualized treatment planning and improved patient outcomes.”
Autoimmune diseases, where the body’s own immune system mistakenly goes on the attack, are much more common in women – and a new study analyzing more than 1.25 million blood cells goes a long way to explaining why.
The analysis, led by a team from the Garvan Institute of Medical Research in Australia, revealed over 1,000 genetic ‘switches’ in immune cells that work differently depending on sex.
In short, these variations in gene activity mean that inflammatory pathways that respond to threats are likely to be busier in women, leading to a greater risk of conditions like lupus and multiple sclerosis.
