Marriage of convenience with a fungus

Researchers found that not all plants react to the fungus in the same way, with some experiencing increased catalpol and citric acid levels while others show little change. The study's findings suggest that the impact of the fungal symbiosis on plant chemistry is not uniform across all plant species.

Screening for autism: There's an app for that

Researchers at Duke University have developed software that tracks and records infants' activity during videotaped autism screening tests. The program is as good as experts giving the test themselves and better than non-expert medical clinicians and students in training, showing promise in identifying early signs of autism.

Gene behind unhealthy adipose tissue identified

Researchers at Karolinska Institutet identified the EBF1 gene driving unhealthy adipose tissue development, associated with increased risk of insulin resistance and type 2 diabetes. The study found that individuals with large fat cells had lower EBF1 expression, altered lipid mobilization, and insulin resistance.

Scientists identify potential vaccine candidate for pediatric malaria

Researchers have identified a substance, known as PfSEA-1, that generates antibodies which can hinder the ability of malaria parasites to multiply, potentially protecting against severe malaria infection. The antigen was associated with reduced parasite levels among children and adults in malaria-endemic areas, and mice exposed to PfSE...

Ancient DNA ends Aussie claim to kiwi origins

A new study by the University of Adelaide's Australian Centre for Ancient DNA has solved a 150-year-old evolutionary mystery about the origins of giant flightless birds. The research found that the kiwi is most closely related to the extinct Madagascan elephant bird, contrary to previous claims.

Being Sardinian puts a smile on the face of the elderly

A new study reveals that Sardinians' active lifestyle, social connections, and access to healthcare contribute to lower levels of depression among the elderly. In contrast, residents from Northern Italy face higher rates of depression due to factors like limited social support and high-stress lifestyles.

'I can' mentality goes long way after childbirth

A Michigan State University study found that women with a strong 'I can' mentality during pregnancy and postpartum periods retained less weight and performed more physical activities. The research team measured physical activity levels, barriers to exercise, and the ability to overcome them in 56 women.

Shattering past of the 'island of glass'

A University of Leicester team has discovered that the entire island was covered in a searing-hot layer of green glass 45 thousand years ago. The volcanic activity on the island provides insights into hazardous eruptions elsewhere, and may help understand undersea currents triggered by earthquakes.

A faster track to the tools that track disease

Researchers at Princeton University have developed a faster method to create 18F radiotracers, which are used to detect and track certain diseases in patients. The new method avoids harsh conditions that scramble the placement of chemical bonds, resulting in improved efficiency and accuracy.

Neuroscience's grand question

Researchers have developed a new theoretical model to understand how cells monitor and self-regulate their properties in the face of continual cellular turnover. The model suggests that neurons use an internal gauge to adjust ion channel expression, but this system can lead to neuronal hyperexcitability and disrupt overall homeostasis.

Laser light needs more bass

Scientists at Vienna University of Technology create an 'optical synthesizer' that combines different frequencies to form a characteristic laser waveform, similar to music. This enables the creation of attosecond pulse radiation hundreds of times more intense than previous methods.

Cyberbullying affects rich and poor alike

A study by Michigan State University researchers suggests that poverty and crime in neighborhoods are significant predictors of cyberbullying. The findings contradict the notion that cyberbullying is a middle-class problem and highlight the need for targeted prevention efforts in low-income communities.
