Lyme Disease Heightens Risk of Mental Disorders, Suicidality

Patients with Lyme disease have a 28% higher rate of mental disorders and are twice as likely to attempt suicide compared to those without the diagnosis. The study reveals that having multiple episodes of Lyme disease is associated with a higher risk of mental health problems, including depression and suicidal behavior.

New solvents to break down plant cellulose for bioethanol

Researchers at Kanazawa University have developed new solvent mixtures containing positive and negative charges to break down plant cellulose for bioethanol production. These solvents are more environmentally friendly and reduce toxicity compared to current methods, enabling the conversion of unused biomass into fuel.

MTU engineers clean up water pollution with sunlight

Michigan Tech researchers developed a model to calculate how particular chemicals break down in surface water using singlet oxygen, which degrades contaminants and helps protect our waterways. The study's findings can aid environmental engineers and scientists in estimating half-lives of chemicals and predicting their degradation rates.

How snakes got their fangs

Researchers from Flinders University discovered that snakes developed venomous fangs by modifying normal tooth structure, creating a 'dental origami' effect. This evolutionary adaptation allowed snakes to inject venom through deepened wrinkles at the base of their teeth, making them highly potent and deadly.

Covid-19 booster jab in the autumn will offer better protection against variants of concern, suggests new study

Researchers found that a second dose of the Pfizer vaccine, especially in those with previous SARS-CoV-2 infection, dramatically increased virus variant neutralising antibody responses. This additional boost increases potential protection against existing and future variants of concern.

Readiness to punish others for selfish behaviour explained by functional brain connections

Researchers found that stronger functional brain connections between the temporoparietal junction and dorsolateral prefrontal cortex are associated with lower levels of punishment for unfair behavior. This suggests that individuals with stronger connectivity in these areas may be less inclined to punish others for selfish actions.

Why sunflowers face east

A study by researchers at the University of California, Davis found that sunflowers facing east produce more offspring due to increased morning warmth attracting bees. East-facing flower heads also tend to be warmer in the morning and release pollen earlier, coinciding with bee visits.

Less stress for women who know their genetic risk for breast cancer

A recent UNSW study found that women who received their polygenic risk score (PRS) for breast cancer experienced minimal regret and reduced distress compared to those who declined. The researchers also discovered that more women reported regret about not knowing their PRS score, highlighting the importance of providing clear informatio...

How society’s inequalities showed up in COVID outcomes

A new study from University of Utah researchers explores how socioeconomic inequalities, particularly in Utah's Salt Lake County, contributed to racial minority groups being unequally affected by the COVID-19 pandemic. The study found that residents of affluent areas had lower rates of infection compared to those in low-income zip codes.

New podcast to focus on life-saving newborn screening research and practice: NBSTRN launches newborn screening SPOTlight

The Newborn Screening Translational Research Network (NBSTRN) has launched a new podcast called Newborn Screening SPOTlight, which shares stories of how newborn screening research saves lives every day. The podcast is co-hosted by Drs. Amy Brower and Kee Chan and features interviews with experts in the field.

Record-breaking extreme heat and cold events may result from similar underlying mechanisms

Researchers studied record-breaking cold air outbreaks in China and North America, finding links to sudden stratospheric warming, polar vortex shifts, and anomalous ocean temperatures. The study suggests that global warming and ocean changes may drive extreme weather events, highlighting the need for further research.

Microplastics: A trojan horse for metals

Researchers have discovered that microplastics can serve as a transport vehicle for metals in the environment, accumulating and releasing these pollutants. The study found significant differences in metal accumulation between different types of plastics, with some metals attaching almost entirely to microplastics.

Brain connectivity can build better AI

A new study demonstrates that artificial intelligence networks based on human brain connectivity can perform cognitive tasks efficiently. Researchers created a brain connectivity pattern and applied it to an artificial neural network, which performed cognitive memory tasks more flexibly and efficiently than other benchmark architectures.

New carnivorous plant must balance trapping prey and being pollinated

Researchers have discovered a new carnivorous plant, Triantha occidentalis, that traps insects near its insect-pollinated flowers, avoiding the death of potential pollinators. The plant's sticky hairs only entrap small midges and insects, allowing larger bees and butterflies to act as pollinators.

Residential mobility is key social determinant of health in people with spinal cord injury

Researchers found that one in four people with spinal cord injury relocated over a five-year period, often to high-poverty areas, increasing health risks. The study highlights the importance of considering residential mobility as a key social determinant of health for this population.

Colleges fall short on mental health outreach to Asian, Latino students

A recent study reveals that colleges struggle to provide adequate mental health support to Asian and Latino students due to interdependent cultural values and shame. The study suggests that culturally tailored treatment services addressing these issues can improve help-seeking behaviors.

Some past sea levels may not have been as high as thought, says study of rising and sinking landmasses

A new study finds that global sea levels during the last interglacial may have been as low as 1.2 meters higher than today, rather than the previously accepted 6-9 meters. This suggests that ice sheet melting was not as extensive as thought, but also raises concerns about future projections.
