In a research review U.K. researchers last year challenged the long-held belief that people with depression suffer from a chemical imbalance in the brain, kicking off a broader debate about treatment for depression.
University of Michigan’s Elissa H. Patterson and Jay Kayser note the clinical status quo, with its heavy emphasis on medication, is not very effective. Nearly three out of four people who take antidepressants do not get complete relief from their symptoms, which can lead to people’s conditions being categorized as “treatment-resistant depression.” They detail many alternatives to medications, some of which may sound familiar but, they contend, have not been integrated into the profession. “The things we do on a day-to-day basis, called lifestyle factors, function as building blocks for a life without depression,” they write.
People who live in the Northeast U.S, as I do, know what a mild winter we’ve had. The lab of Boston University biologist Richard Primack has been researching how climate change affects annual rhythms such as the arrival of leaves and migration of birds in the springtime, using the extensive records of Henry David Thoreau in Concord, Massachusetts, for many studies. In his latest article for us, Primack and his colleagues looked more broadly and found that “as temperatures warm, deciduous trees across eastern North America are advancing their leaf-out timing faster than native wildflowers are responding.” This mismatch can mean that in some regions native
wildflowers are more likely to be shaded out by trees.
One of the most well-read science stories last week was a study on the advanced communication abilities of bees, which teach younger bees with a “waggle dance” where to forage. Our editors also uncovered a study on widely inconsistent EPA enforcement of pollution laws by state, and an ethicist makes the case that the biggest risk from generative AI such as ChatGPT is people’s tendency to attach human characteristics to our tools and machines.

An overreliance on medication as the first-line treatment for depression can lead some people to be labeled with treatment-resistant depression when there are other viable alternatives for relief.

Native wildflowers, such as these Dutchman’s breeches (Dicentra cucullaria) that bloom early in spring are losing access to sunlight as trees leaf out earlier.

Many beloved wildflowers bloom in early spring, while trees are still bare and the flowers have access to sunlight. Climate change is throwing trees and wildflowers out of sync.

Another atmospheric river is hitting the state, raising flood risks as rain falls on deep snowpack. Rain on snow is also a growing problem as the planet warms.
