With a contemporary smartphone, capturing, transmitting, and replicating sounds and visuals is a breeze, yet replicating scents remains elusive. If you want to change this, consider joining the 2025 @DR_E_A_M Olfaction Challenge at https://t.co/sNJGvwkZ5j. @jeriscience

Scientists at Firmenich https://t.co/av6voiNc9u and now Givaudan https://t.co/zGC6gZ24xn report several olfactory receptors that appear to map cleanly onto specific odor notes (earthy, grapefruit, woody, etc.).

@DR_E_A_M @jeriscience My favorite part of these challenges is after the competition closes. All participants get together and work collaboratively on a manuscript summarizing key insights and where the field stands. Join us!

@DR_E_A_M @jeriscience Building on last year's Mixture Discriminability Challenge, we're offering a dataset of 650+ blends, each assessed by trained panelists using a 51-word scent lexicon.

@DR_E_A_M @jeriscience Most existing models predict odor perception at just one concentration. Yet, some odorants dramatically shift in quality as concentration changes—such as grapefruit mercaptan, pleasantly fruity at low concentrations but distinctly sulfurous at high levels.

@DR_E_A_M @jeriscience This year, we have two challenges: 1) Predicting how odor quality changes with concentration, and 2) Describing an olfactory mixture. You can make up to three leaderboard submissions until July 21st, with one final submission allowed before August 8th.

@DR_E_A_M @jeriscience Last year, we ran the second DREAM Olfaction Prediction Challenge https://t.co/bUz6aWqVUm . This time focusing on predicting the similarity of mixture pairs.

@DR_E_A_M @jeriscience Ten years ago the first DREAM Olfaction Prediction Challenge launched to predict the smell of a molecule from its structure. This led to a publication establishing benchmarks https://t.co/j0E3ZtXRVH , and then a subsequent surge in predictive modeling.

YALL!!! It's a wrap on the 2024 Monell Science Apprenticeship Program. And this year, it's a tie-- We have not one, but two Sense-Sational Science Award winners, Aiden and Mustafa!

We're recruiting! The Wachowiak lab at @UtahNeurosci has postdoctoral positions available. Interested in odor coding, neural dynamics, active sensing, in vivo imaging/ephys? Check us out! Please RT. https://t.co/do5jIX6XhJ #ScienceJobs #Neuroscience

Drugs like Ozempic are great for weight loss, but they make some people feel sick. We discovered that the brain circuits mediating the appetite suppression are distinct from those that mediate nausea – a finding that may be leveraged to develop more selective GLP1-based drugs.

Today in @Nature-- @MonellSc researchers, led by @AmberAlhadeff, share new findings that point towards a possible way to reduce adverse side effects of popular next-generation obesity medications like GLP1-based drugs, known as semaglutide and marketed as Ozempic® and Wegovy®

Amazing @JLand52 will be presenting!

Curious how to use predictive models to discriminate between odor mixtures & unravel the mysteries of our sense of smell? Join @jeriscience from @IBMresearch & @DR_E_A_M for the Olfactory Mixtures Prediction Challenge webinar today (noon PT) to learn more:
