Why “born digital firms” should have a physical presence in foreign markets

A new study published in Global Strategy Journal highlights the importance of a physical presence in foreign markets for born digital firms. The research found that these firms are more likely to deploy foreign direct investment in far-away and culturally different countries to overcome geographical and cultural challenges.

The quantum spin liquid that isn't one

A team of researchers at Vienna University of Technology and Toho University in Japan investigated the electrical resistance of κ-(BEDT-TTF)2Cu2(CN)3 as a function of temperature and pressure. They found that the material exhibits properties similar to those of helium-3, contradicting the theory of a quantum spin liquid.

Physicists find unusual waves in nickel-based magnet

Researchers found that two outermost electrons from each nickel ion behaved differently, cancelling each other out in a phenomenon called a spin singlet. This led to the discovery of two families of propagating waves at dramatically different energies, contradicting expectations of local excitations.

One in five suicides involved intimate partner problems

A new study from the University of Georgia and CDC found that 20% of suicides between 2003 and 2020 were related to issues like breakups, conflict, divorce, and mental health problems. Intimate partner problems were more common among individuals who experienced mental health issues, life stressors, and recent legal issues.

A recent research on why pundits can be unreliable

Researchers found that forecasters have an incentive to misreport when their reputation is at stake, with higher levels of misreporting in less uncertain situations. The study suggests firms should trust expert advice when uncertainty is high and link evaluations to ex-post accuracy to reduce misreporting.

BU study: no significant differences in mortality, adverse events in patients taking thyroid medications

A recent study from Boston University School of Medicine found no significant differences in mortality among patients treated with propylthiouracil (PTU) or methimazole (MMI) for thyroid storm. The researchers compared the two drugs using a national database of hospitalization data and found no significant differences between the groups.

Salmonella detection

A team of researchers developed a simple and portable test system to detect salmonella in food, eliminating the need for expensive analytical equipment. The assay uses a nucleic acid probe that is cleaved by an RNase enzyme specific to salmonella, resulting in a clear red spot on an absorbent pad indicating contamination.

Teasing strange matter from the ordinary

Researchers have made the first-ever observations of how lambda particles, a form of strange matter, are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). The study reveals that diquarks, pairs of quarks and gluons, can march through atomic nuclei, contributing to the formation of lambdas.

When both mom and dad maltreat their child

A new study found that factors such as substance use, housing insecurity, and intimate partner violence are linked to an increased risk of both parents being involved in physical or sexual abuse. However, other risk factors like economic insecurity and parental mental health problems were not associated with any type of maltreatment.

Protein that drives the development of alcohol-associated liver disease identified by IU researchers

A team of researchers from Indiana University School of Medicine has identified Pyruvate dehydrogenase kinase 4 (PDK4) as a crucial mediator of alcohol-induced liver injury. PDK4 plays a key role in the formation of calcium channels at the ER-mitochondria interface, leading to mitochondrial dysfunction and accumulation of calcium ions.
