Why discarded brain ‘noise’ matters: Overlooked networks may reshape mental health treatment
Scientists who use imaging to understand the brain’s complexity often focus on the strongest signals and ignore the rest. But this strategy, researchers warn, may reveal only the tip of the iceberg. A study published in Nature Human Behavior reveals that connections routinely overlooked as “noise” during neuroimaging data analysis can predict behavior with remarkable accuracy—and implicate entirely different brain networks. The finding could open many new targets for treating psychiatric illness, the researchers say.
“Many studies that rely on techniques like feature selection—which simplifies the brain down to a narrow slice—might only uncover a small part of the true neurobiology that underlies a given behavior,” says lead author Brendan Adkinson, Ph.D., an MD-Ph. D. student at Yale School of Medicine.
“Our study suggests that there may be multiple, non-overlapping networks capable of predicting a given behavior just as well.”
Researchers directly observe muonic molecules critical to muon catalyzed fusion
Scientists have directly observed muonic molecules in resonance states for the first time, using a high-resolution X-ray detector, a new Science Advances study reports.
Resonance states are critical in determining the reaction rate of muon catalyzed fusion (µCF), a process that utilizes elementary particles known as muons. Within muonic molecules, the nuclei are confined in extremely close proximity, enabling nuclear fusion to occur even at room temperature without the need for plasma.
Currently, research aimed at the practical application of nuclear fusion is underway worldwide. In principle, fusion offers highly safe energy with no risk of runaway accidents. It utilizes fuel easily extracted from seawater and produces clean energy without carbon dioxide emissions.
FDG-PET for Estimating Outcomes After Initial Treatment for Metastatic Breast Cancer
Among patients with newly diagnosed metastatic BreastCancer (MBC), a clinical cohort trial evaluated early treatment response using 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) compared with standard computed tomography (CT) assessment.
FDG-PET after only 2 weeks of treatment identified patients with MBC with distinct long-term outcomes. Incorporating early FDG-PET can improve outcome estimation of standard CT assessment.
Question Does repeated 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET) after 2 weeks of treatment improve outcome estimation in metastatic breast cancer compared to standard diagnostics?
Findings This clinical cohort trial including 200 patients found that those without disease progression on early FDG-PET had better median progression-free survival (PFS) and overall survival (OS) than patients with disease progression. Among patients without progression on computed tomography (CT) after 8 weeks, those with progression on early FDG-PET had a median OS of 22.3 months, whereas patients without progression on both CT and early FDG-PET had an OS of 50.1 months.
Meaning Early FDG-PET imaging may improve outcome estimation in newly diagnosed metastatic breast cancer compared to standard CT alone.
Scientists stunned as Mars dust storms blast water into space
Mars may look like a frozen desert today, but new evidence suggests its watery past didn’t simply fade away quietly—it may have been blasted into space by powerful dust storms. Scientists have discovered that even relatively small, localized storms can hurl water vapor high into the atmosphere, where it breaks apart and escapes.
Today, Mars is known as a cold, dry desert, but its surface tells a very different story. Ancient channels, water-altered minerals, and other geological features show that the planet once had abundant water and a far more dynamic environment. Understanding how this wetter world transformed into the barren landscape we see now remains a major question in planetary science. While scientists have identified several processes that contributed to water loss, much of Mars’ missing water is still unaccounted for.
A new international study published in Communications: Earth & Environment brings scientists closer to solving this mystery. Researchers found that an unusually intense but localized dust storm was able to push water vapor high into Mars’ atmosphere during the Northern Hemisphere summer, a season previously thought to play little role in this process.

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a theory of quantum gravity… which means we need gravitons. But it also seems like the laws of physics make it impossible to ever detect this quantum particle of gravity. Almost like the universe is set up to keep the final answer forever out of our reach. So, can we outsmart the universe, catch a graviton, and finally solve physics?

We human beings sit roughly midway between the sizes of atoms and galaxies, and both must be so perfectly structured for us to exist. It’s called ‘fine-tuning’ and it’s all so breathtakingly precise that it cries out for explanation. To some, fine-tuning leads to God. To others, there are non-supernatural explanations. Both are startling.
