A collaboration unveils a novel strategy for identifying key proteins in organelle communication. This approach advances our ability to pinpoint proteins essential for organelle interactions within specific spatial and temporal contexts.
In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.
An international research team has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds.
Wildebeest migrations have become a rarer sight in Africa as humans continue to interrupt their historic migratory routes with roads, fences, cities, livestock and farmland. This has led to genetic decay in those herds that are no longer able to roam freely, according to new research.
The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate. Scientists have devised a solution: Cas13d-NCS. This new molecular tool allows CRISPR RNA molecules that are located within the nucleus of a cell to move to the cytoplasm, making it highly effective at neutralizing RNA viruses. This advancement opens doors for precision medicine and proactive viral defense strategies.
A study suggests that people with diets high in seafood may face a greater risk of exposure to PFAS -- the family of human-made toxins known as 'forever chemicals' -- than previously thought. The researchers stress the need for more stringent public health guidelines that establish how much seafood people can safely consume to limit their exposure, particularly in coastal areas where seafood is frequently eaten.
Oceanographers have shown for the first time the important role of the 'mixing down' of oxygen in maintaining healthy conditions in the deep waters.
A star's magnetic field must be considered in order to correctly determine the characteristics of exoplanets from observations by space telescopes such as Kepler, James Webb, or PLATO. Researchers show that the distribution of the star's brightness over its disk depends on the star's level of magnetic activity. This, in turn, affects the signature of an exoplanet in observational data. The new model must be used in order to properly interpret the data from the latest generation of space telescopes pointed at distant worlds outside our Solar System.
Consuming sugar-sweetened drinks in the first few years of childhood can be linked to poor diet patterns that increase the risk of obesity in later life, according to a new study.
A study has disentangled the mechanisms behind one of the ways melanoma cancer cells develop resistance to treatment. The study found that, in response to some drugs, melanomas can 'break' parts of their BRAF gene, which is mutated in 1 in 2 melanomas. This helps the tumor create alternative versions of the protein which lack regions targeted by one BRAF inhibitors, one of the main drugs used to treat this type of cancer, making treatment less effective. The findings pave the way for alternative strategies to treat BRAF-mutated melanoma, which leads to relapse in 50% of patients within a one-year period.
It is one of the world's most spectacular sights -- huge flocks or 'flamboyances' of flamingos around East Africa's lakes -- as seen in the film Out of Africa or David Attenborough's A Perfect Planet. But new research has revealed how the lesser flamingo is at danger of being flushed out of its historic feeding grounds, with serious consequences for the future of the species.
Beyond the seven SI units lie the 22 derived units
Behind the picture postcard exterior, critics say, is a country that has done too little for the planet and acted as a business hub for some of the most powerful international corporations in fossil fuels and mining.
Computer simulations previously had predicted that the blending of stellar material during such a merger could create a magnetic field in the combined star born in this process.
Neural crest cells -- embryonic pluripotent cells within the facial primordium -- may be necessary for forming proper animal facial structures. Researchers have produced neural crest cell-rich aggregates from human pluripotent stem cells and developed a method to differentiate them in cell populations with a branchial arch-like gene expression pattern.
When the brain has trouble filtering incoming information and predicting what's likely to happen, psychosis can result, research shows.
Human papillomavirus (HPV) is the second most common cancer-causing virus, accounting for 690,000 cervical and other cancers each year worldwide. While the immune system usually clears HPV infections, those that persist can lead to cancer, and a new finding suggests that certain women may have a genetic susceptibility for persistent or frequent HPV infections. These genetic variants could raise a woman's risk of getting cervical cancer from a high-risk HPV infection.
New research reveals AI-generated responses can make humans 'feel heard' but an underlying bias toward AI devalues its effectiveness.
What if changes in a person's stress levels could be detected while they sleep using wearable devices? A new study find changes in perceived stress levels reflected in sleep data -- an important step towards identifying biomarkers that may help flag individuals in need of support.
When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data suggest there were originally three stars in the system, until two of them clashed and merged. This violent event created the surrounding cloud and forever altered the system's fate.
