Dissolving implantable device relieves pain without drugs

Researchers have developed a small, soft, flexible implant that relieves pain on demand and without the use of drugs. The first-of-its-kind device could provide a much-needed alternative to opioids and other highly addictive medications. It works by softly wrapping around nerves to deliver precise, targeted cooling, which numbs nerves and blocks pain signals to the brain. After the device is no longer needed, it naturally absorbs into the body -- bypassing the need for surgical extraction.

Seat assignments drive friendships among elementary school children

Most teachers focus on academic considerations when assigning seats. A new study is the first to show that these classroom seat assignments also have important implications for children's friendships and the enormous influence that teachers wield over the interpersonal lives of children. Friendships reflect classroom seat assignments. Students sitting next to or nearby one another were more likely to be friends with one another than students seated elsewhere in the classroom. Moreover, longitudinal analyses showed that classroom seating proximity was associated with the formation of new friendships. After seat assignments changed, students were more likely to become friends with newly near-seated classmates than with those who remained or became seated farther away.

Are we born with a moral compass?

Researchers found that preverbal infants can make and act on moral judgments about antisocial behavior in a third party. Using a new cognitive paradigm with gaze tracking, researchers were able to show that 8-month-old infants can engage in third-party punishment. This indicates that humans may have acquired morality through evolution, and opens the door for future experiments to investigate unexplored elements of infant cognition.

Existing cancer therapy in narrow use shows significant activity against other cancers

A drug currently used in just 1% of cancers has significant potential against the remaining 99%, according to a new study. Ivosidenib, or AG-120, is currently used against cancers that have a mutation in the IDH1 gene. However, study results show that Ivosidenib is also effective against unmutated, or 'wild-type' IDH1. The protein coded by the IDH1 gene in cancers helps cancer cells survive in a stressful tumor environment, so any inhibitor medication that could weaken this defense mechanism is considered a promising therapy.

Pre-historic Wallacea: A melting pot of human genetic ancestries

The Wallacean islands of present-day Eastern Indonesia have a long history of occupation by modern humans. Notably, the maritime expansion of Austronesian speakers into Wallacea left archaeological traces of a Neolithic lifestyle and a genetic imprint still detectable in Eastern Indonesians today. To gain further insights into Wallacea's settlement history, scientists sequenced and analyzed sixteen ancient genomes from different islands of Wallacea, finding evidence for repeated genetic admixtures starting at least 3,000 years ago.

Neuroscientists identify role of basolateral amygdala neurons

The basolateral amygdala (BLA) is a region of the brain that has been almost exclusively studied in the context of fear and emotion. Only recently have researchers begun to question whether the BLA may play a larger, overarching role in memory and behavior. Yet almost nothing is known about the neuronal activity of the BLA during naturalistic behavior. To address these questions, neuroscientists at the Sainsbury Wellcome Centre at UCL observed the neuronal activity in this brain region while rats freely engaged with a variety of different ethological stimuli.  Interactions with ethological stimuli are relevant to the animal's survival and to the propagation of its genes, and include food, prey and conspecifics. In a new study, published today in Cell Reports, the researchers demonstrate strong responses to these classes of events in the BLA.

Body versus brain: New evidence for an autoimmune cause of schizophrenia

Researchers have found that some people with schizophrenia have autoantibodies -- which are made by the immune system and recognize the body's own proteins, rather than outside threats such as viruses or bacteria -- against NCAM1, a protein that's important for communication between brain cells. The patients' autoantibodies also caused schizophrenia-related behaviors in mice. These findings may improve the diagnosis and treatment of a subset of patients with schizophrenia.

Some blood pressure medicine may decrease the aneurysm rupture risk for people with high blood pressure

A new study has found that RAAS inhibitors, a class of blood pressure-lowering medicine, may be better at reducing the risk of brain aneurysm rupture. People with a brain aneurysm -- a weakened area of a blood vessel -- who were being treated for high blood pressure with medication from the class of drugs called RAAS inhibitors had a significantly lower risk of a ruptured aneurysm compared to those who took other blood pressure medications. These results indicate that RAAS inhibitors may be preferable to other blood pressure-lowering medications and could inform treatment decisions for people with high blood pressure who have unruptured intracranial aneurysms.

Forests: Spatial aspects of biodiversity, homogenization threat to forest ecosystems

A study highlights the importance of spatial aspects of biodiversity for healthy functioning of naturally occurring forests. Biologists determined that tree beta diversity -- a measure of site-to-site variation in the composition of species present within a given area -- matters more for ecosystem functioning than other components of biodiversity at larger scales. The research also shows that the relationship between beta diversity and tree biomass strengthens with increasing spatial scale (the size of an area) a finding that has implications for conservation planning.
