- newHow relaxing COVID-19 restrictions could pave the way for vaccine resistance
A new article outlines how relaxing Covid-19 restrictions could pave the way for new vaccine-resistant virus mutations. It describes how we are in an 'arms race' with the virus and how rising cases could provide opportunities for it to evolve into even more transmissible variants. The researchers say that any new variants could be more virulent, more vaccine resistant, and more dangerous for children and vulnerable groups such as transplant patients.

Positive trends in global education access are expected to decrease dementia prevalence worldwide by 6.2 million cases by the year 2050. Meanwhile, anticipated trends in smoking, high body mass index and high blood sugar are predicted to increase prevalence by nearly the same number: 6.8 million cases.

- newMore than just walking: A new role for core brain region
For decades, a key brain area has been thought to merely regulate locomotion. Now, a research group has shown that the region is involved in much more than walking, as it contains distinct populations of neurons that control different body movements. The findings could help to improve certain therapies for Parkinson's disease.

A new study shows that over the course of five years, patients who had bariatric and metabolic surgery to treat uncontrolled type 2 diabetes reported greater physical health, more energy, less body pain, and less negative effects of diabetes in their daily lives, compared with patients who had medical therapy alone for their diabetes.

- newFruit fly offers lessons in good taste
The fruit fly has multiple taste organs throughout its body to detect chemicals, called tastants, that signal whether a food is palatable or harmful. It is still unclear, however, how individual neurons in each taste organ act to control feeding. To explore this question, a team used the fly pharynx as a model to study whether taste information regulates sugar and amino acid consumption at the cellular level.

- newNew strategy for drug design: Keeping copper atoms closer to keep bacteria away
Hydrogen peroxide reacts with copper to produce hydroxyl radicals with strong antibacterial properties. However, this requires high copper concentrations because two copper atoms have to come close together, which occurs by chance. Now, scientists have engineered a long polymer with copper-containing side units that create regions with locally high copper density, boosting the antibacterial activity of hydrogen peroxide and paving the way to a new drug design concept.

Researchers have discovered that decisions based on visual information, which involve a complex stream of data flowing forward and backwards along the brain's visual pathways, is broadcast widely to neurons in the visual system, including to those that are not being used to make the decision.

Researchers discovered that although the brain regulates feeding for pleasure and for hunger through serotonin-producing neurons in the midbrain, each type of feeding is wired by its own independent circuit that does not influence the other type of feeding.
