Sniffing out stem cell fates in the nose

UC Berkeley scientists have developed a new technique to track individual stem cells in the nose, uncovering clues that could help restore smell to those who have lost it. The team used single-cell RNA sequencing and statistical analysis to identify the molecules that trigger stem cell differentiation into specific cell types.

Not survival of the fittest for Tassie devils

Researchers found that devils with higher fitness rates are more likely to contract devil facial tumour disease (DFTD), a transmissible cancer. The study suggests that socially dominant individuals may be more susceptible due to their aggressive behavior and mating encounters.

Populations adapt as nature and nurture work together

Researchers found that genetic variations influence fruit fly larvae's ability to associate odors with pain and pleasure, leading to better decision-making about pupation. The study suggests a link between learning and environmental cues, highlighting the complex interplay of nature and nurture in shaping behavior.

Better a 'no' than no answer at all

Researchers investigated how social exclusion affects individuals and found that even small indications of integration and attention can reduce distress. Receiving minimal attention via a letter or email can make rejection more bearable.

UC3M researchers analyze link between employment status and domestic violence

Research based on macro-surveys found that households with both members working have the lowest incidence of domestic violence. Higher education levels and younger women are also associated with reduced risk. The study suggests different policy approaches for vulnerable groups, promoting gender equality through education and employment.

Migratory seabird deaths linked to hurricanes

A Duke University-led study maps the sooty tern's annual migratory path and reveals its direct correlation with hurricane-forming storms in the Atlantic. The researchers warn that stronger hurricanes may increase due to climate change, posing a new threat to these iconic seabirds.

The human sense of smell: It's stronger than we think

According to Rutgers University researcher John McGann, humans can detect and discriminate an extraordinary range of odors, rivaling that of rodents and dogs. The human olfactory bulb is similar in size and number of neurons to other mammals, challenging the long-held misconception about human sense of smell.
