Cancers can be detected in bloodstream three years prior to diagnosis Detection of cancer before a clinical diagnosis could give patients and caregivers more time for intervention and may lead to better outcomes because tumors are more likely to be curable

Genetic material shed by tumors can be detected in the bloodstream three years before cancer diagnosis, according to a study led by investigators at Johns Hopkins University.

That study was made possible with federal funding. Now, many studies like this are canceled. hub.jhu.edu/2025/06/04/...

Prefrontal encoding of an internal model for emotional inference - Nature Neurons in the rodent dorsomedial prefrontal cortex encode a flexible internal model of emotion by linking directly experienced and inferred associations with aversive experiences.

... neurons in the rodent dorsomedial prefrontal cortex (dmPFC) [link] sensory stimuli in the environment with aversive events, whether they were directly or *indirectly* associated with that experience....

Dopaminergic processes predict temporal distortions in event memory Our memories do not simply keep time - they warp it, bending the past to fit the structure of our experiences. For example, people tend to remember items as occurring farther apart in time if they spa...

New from our lab: your brain doesn’t just remember time - it bends it.

We show that the dopamine system responds to natural breakpoints in experience, and this relates to more stretched memories of time. Blinking also increases, signaling encoding of new memories.

Zoomed out crowd shot of 34,000 people in downtown Denver with Colorado mountains in the background

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back.

This was the largest political gathering in Denver since Obama in 2008.

Also bigger than the 2024 DNC.

And the largest ever rally in Bernie’s career (and obviously, mine too).

As Cervical Cancer Deaths Plummet, Experts Credit HPV Vaccine HPV can cause a variety of cancers, including cervical. New mortality data for women under 25 point to the success of the HPV vaccine.

There is a vaccine against a virus that causes a particularly pernicious cancer, and since it was introduced deaths from that cancer have dropped by more than 60%. An unmitigated triumph of human genius.
