Hot spot at Hawaii? Not so fast

Researchers developed a method to analyze hot spot tracks and found most groups are fixed and relatively motionless, moving at about 4 millimeters per year. This contradicts previous findings that suggested hot spots moved as much as 33 millimeters a year.

Novel approach to track HIV infection

Researchers have developed a novel approach to track HIV infection by identifying individual viral particles associated with infection. The new method reveals that uncoating leading to infection occurs early in the cytoplasm, around 30 minutes after cell fusion.

Smart computers

A team of scientists from the University of Freiburg has created a self-learning algorithm that decodes human brain signals measured by an electroencephalogram (EEG) with high accuracy. The algorithm, based on brain-inspired models, can recognize and differentiate between various behavioral patterns from different movements, making it ...

Virus with an eggshell

Researchers found that avian flu viruses isolated from humans have the same gene sequences as those from birds, suggesting transmission through the mineral layer. The mineralized shell changes the electric surface potential of the virus, allowing it to adsorb efficiently onto host cells.

Paper: Clinical signs best predictors of mortality in critically ill calves

A new study suggests that clinical signs, such as gastrointestinal problems and septic arthritis, are better indicators of mortality in neonatal calves with diarrhea than blood pH levels. The research found that these clinical signs were significant determinants of mortality, while blood pH levels were only a predictor when they droppe...

A map of the cell's power station

Scientists from the University of Freiburg successfully mapped the mitochondrial protein landscape, revealing over 200 new proteins not previously attributed to this organelle. This study provides a basis for studying the potential new functions of mitochondria and understanding various diseases.

Solutal Marangoni flows of miscible liquid drive transport without surface contamination

A research team led by Professor Hyoungsoo Kim quantified the Marangoni effect in miscible liquids, revealing a new mechanism for driving transport without surface contamination. The findings have potential applications in removing impurities from surfaces and developing alternative materials to surfactants.

A better way to measure mortality trends?

Researchers analyzed years of life lost due to top causes of death in the US from 1995 to 2015, revealing disparities and successes. Life-years lost showed that cancer caused more life-years lost than heart disease, despite heart disease being the leading cause of death.

Slowing dangerous bacteria may be more effective than killing them, researchers report

A new study reveals that manipulating bacterial communication can help the body defeat an infection without causing drug-resistant strains. By targeting the dormancy-signal molecule, researchers hope to develop molecules that can disrupt specific bacteria's language, reducing resistance development.

Should I stay or should I leave?

A new study investigates the decision-making process in relationships, revealing common pros and cons of staying versus leaving. Participants weighed reasons such as emotional intimacy, investment, and personality traits, with married individuals citing more constraint-based reasons for staying.

Mind flex

A Harvard Medical School study found that neurons involved in learning and memory are less stable than previously thought, but more flexible. This flexibility allows the brain to easily integrate new information and adapt to changing circumstances.
