Quasi-particle swap between graphene layers

Belgian scientists applied a particle physics analogy to describe exciton behaviour in two graphene layers, mimicking parallel worlds. The approach reveals swapping effects between layers under specific electromagnetic conditions, similar to brane theory predictions.

Symptoms of depression causally linked to risk of coronary heart disease in UK

A recent study published in the European Journal of Preventive Cardiology found a causal link between depression symptoms and an increased risk of coronary heart disease. In contrast, no such association was found with stroke risk. The Whitehall II study, which followed over 10,000 civil servants in the UK for 20 years, suggests that r...

Diamond film possible without the pressure

Scientists at Rice University and Russia have calculated a road map for creating ultra-thin diamond films without high pressure. The 'phase diagram' outlines conditions necessary to turn stacked graphene sheets into flawless diamond lattices, with potential applications in nanocapacitors, electronics, and nano-optics.

How smartphones help find avalanche victims

Researchers have developed a smartphone-based system that can locate buried avalanche victims using satellite navigation, promising faster and more precise rescue operations. The Galileo-LawinenFon system uses the combined signals of GPS, Galileo, and GLONASS satellite systems to pinpoint accident victims in seconds.

Hormone in crab eyes makes it possible for females to mate and care for their young

Scientists discovered a female-specific hormone in blue crab eyestalks that regulates development of reproductive structures for mating and childcare. This hormone is required for maternal care and triggers development of special receptacles to store sperm, as well as hair-like structures to hold fertilized eggs.

Mosquito sperm have 'sense of smell'

Researchers at Vanderbilt University discovered that mosquito sperm contain a suite of specialized chemical sensors called odorant receptors, which drive the rapid increase in movement. These findings suggest a new paradigm for regulating insect reproduction and could provide a powerful approach for controlling insect populations.

Is high blood pressure the new HIV epidemic?

A group of experts warn that high blood pressure could be as devastating to global health as HIV, with potentially more deaths over the next 20 years. Despite similarities between the two conditions, there is 'denial' and misunderstanding about hypertension's impact, hindering effective treatment and management.

Chemical stem cell signature predicts treatment response for acute myeloid leukemia

A study by Einstein researchers identified a chemical 'signature' in blood-forming stem cells that predicts which AML patients will respond to chemotherapy. The findings, based on nearly 700 patient data, could help physicians identify patients who would benefit from standard treatment and spare them debilitating side effects.

Blue light may fight fatigue around the clock

Researchers from Brigham and Women's Hospital found that blue light exposure improves alertness and performance during the day and night, reducing fatigue. The study used specialized equipment to compare the effects of blue and green light on 16 participants, showing significant improvements in alertness and reaction times.

New scientific field looks at the big picture

The new field of macrosystems ecology is being touted as a solution to tackle environmental problems such as climate change and invasive species. By integrating biology with other fields and using vast amounts of data, ecologists can study complex systems at broad scales.

Simple, at-home test will detect most colorectal cancers

A new evidence review finds that fecal immunochemical tests (FITs) detect about 79% of colorectal cancers and correctly identify 94% of patients without cancer. The test is simple, can be done at home, and can save lives, making it a great tool for assessing which patients have cancer and which do not.

Women with schizophrenia at higher risk of pregnancy and delivery complications: Study

A landmark study by researchers found that women with schizophrenia are nearly twice as likely to experience pre-eclampsia, pre-term birth, and other serious pregnancy and delivery complications. The study also revealed high birth weights, increased rates of hypertension and thromboembolic disease in pregnant women with schizophrenia.

Discovery aids in fight against antifungal drug resistance

Researchers have determined the complex structure of a key cell membrane protein involved in sterol metabolism and resistance in a yeast model. The study's findings provide new insights into mechanisms underlying fungal resistance to triazole drugs, which can help develop new broad-spectrum drugs with minimal side effects.
