Staying alive: Scientists eye up gene required for the survival of an important retinal neuron

Researchers at OIST Graduate University identified the strip1 gene as essential for keeping retinal ganglion cells alive. The gene suppresses Jun-mediated apoptosis, promoting correct neural circuit formation in the retina. This finding opens promising new avenues for treating diseases like glaucoma.

Study involving investigators from Mayo Clinic, Baylor College of Medicine applies drug-gene testing to improve patient care and reports outcomes

A new study from Mayo Clinic and Baylor College of Medicine found that targeted genomic information can significantly impact drug prescribing practices. By applying drug-gene testing, clinicians can identify nearly every patient as a potential candidate for preemptive testing, particularly for drugs with unknown genetic influences.

Shining a light on protein aggregation in Parkinson’s disease

A novel system to control protein aggregation in a model of Parkinson’s disease suggests that aggregation of alpha-synuclein plays a critical role in disrupting neuronal homeostasis and triggering neurodegeneration. Light treatment led to formation of Lewy body-like aggregates, neurodegeneration, and Parkinson-like motor deficits in mice.

An improved ink for colon tattoos

Researchers have created a new type of colon tattoo ink that is more biocompatible and less prone to diffusion than existing inks. The ink uses metal-derived nanoparticles and polymers to adhere to the submucosal surface in the colon, allowing for better identification and removal of complex polyps and tumors.

Evidence continues to build that organ donation from people dying after a positive COVID-19 test is safe and does not transmit SARS-CoV-2 to the recipient

The European Society of Clinical Microbiology and Infectious Diseases finds organ donation from COVID-19 patients is safe and does not transmit SARS-CoV-2. Recipients with asymptomatic infections are also now eligible for transplant, but must be triple-vaccinated.

Information processing tied to emergence of hierarchy in human societies

A new study uses a vast dataset to test the idea that hierarchical structures in human societies arose from cognitive limits on information processing. The research found that for small-scale societies, population size and governing system development influence hierarchy emergence, while medium- and large-scale societies are shaped by ...

Bionic wing flaps improve wind energy efficiency

Scientists from China have developed a bionic approach to improve wind turbine performance by combining features of a seagull's wing with an engineered flow control accessory. The combined flow control improves lift and delays stalling at high angles of attack, increasing the efficiency of wind energy turbines.

Getting fuel to an invading cell's front line

Researchers have identified two glucose transporters that disrupt the energy supply to invading worm cells and stop them in their tracks. By deactivating these genes, glucose and ATP levels dropped, and worm cells stalled their spread. This discovery could lead to new ways to cut off cancer cells' fuel lines and prevent metastasis.

Ductile-regime vibration texturing: Create structural colors on brittle silicon

Researchers have successfully created high-quality, crack-free microstructures on silicon surfaces in the ductile regime using elliptical vibration cutting. The technique allows for high-aspect-ratio feature generation with minimal interference, enabling structural coloration and potential applications in displays, sensing, and more.

Working shifts may delay the onset of menopause

A new study suggests that working non-traditional shifts may delay the onset of natural menopause in women. The researchers found a significant association between rotating shifts and later age at menopause, possibly due to disruptions in circadian rhythms. Further investigation is necessary to determine the underlying mechanisms.

Evidence is currently insufficient to show omicron variant has a shorter period of infectiousness compared with previous variants

The omicron variant's infectiousness period is uncertain, with evidence suggesting it may not be shorter than previous variants. Dr Marjolein Irwin-Knoester recommends a maximum of 7-day isolation for most cases, striking a balance between virus infectivity and community acceptance.

Research: Partnership between humanitarian organizations and governments is essential for providing cash assistance to refugees

Research from Indiana University reveals that cash assistance is a double-edged sword, harming both refugees and local residents if not implemented correctly. Humanitarian organizations can extend cash assistance to host regions with market power by partnering with local governments.

Men and women process pain signals differently

A new study published in BRAIN shows that a neuronal growth factor called BDNF plays a major role in amplifying spinal cord pain signalling in male humans and male rats, but not in female humans or female rats. This discovery has significant implications for the development of new treatments for chronic pain.

Correcting night blindness in dogs

Researchers have developed a gene therapy that restores night vision in dogs with congenital stationary night blindness (CSNB), a condition affecting the ON bipolar cells. The treatment enables dogs to navigate mazes in dim light and has a lasting therapeutic effect, paving the way for potential human treatments.

"Advanced" countries’ wealth depends on the appropriation of resources and labour from the global South

A study by Jason Hickel reveals that the global North appropriates vast resources and labor from the global South through price differentials in international trade, resulting in a net drain of $10.8 trillion in 2015. This unsustainable practice perpetuates global inequality and ecological breakdown.

Team identifies compound with potent antiseizure effects

A team of researchers has discovered a compound called TC-2153 that reduces seizure severity in mice with temporal lobe epilepsy by decreasing the activity of hippocampal neurons. The study found that female sex hormones play a role in the efficacy of TC-2153, which may be relevant to sex differences seen in temporal lobe epilepsy.
