For the first time, scientists have observed planets forming around a star other than our sun.Researchers used the James Webb Space Telescope and ALMA to observe planet-building material forming near the young star. This stunning discovery may help us understand how our own solar system formed 4.6 billion years ago.Astronomers have observed the first solid materials forming around a young star known as HOPS-315 , the earliest stage of planet formation ever seen outside of our solar system.The emergence of a planetary system that may eventually resemble the solar system has been observed by astronomers. The team was able to determine when the young star HOPS-315, which is about 1,300 light-years away, started to form the specks of material that will eventually form planets.Data from the Atacama Large Millimeter/submillimeter Array (ALMA), a network of 66 radio telescopes situated in the northern Chilean desert, and observations from the James Webb Space Telescope (JWST) enabled the discovery, as per a report by Space.Melissa McClure, a professor at Leiden University in the Netherlands and the study's lead author, says, "For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our Sun." The study was published in Nature today.'We're seeing a system that looks like what our Solar System looked like when it was just beginning to form," says co-author Merel van 't Hoff, a professor at Purdue University in the United States, who likens their findings to "a picture of the baby Solar System." The team's findings were released in the journal Nature on Wednesday, July 16, as per a report by ESO.Around HOPS-315, a "proto" or baby star that is located about 1300 light-years away from us and is comparable to the young Sun, this newborn planetary system is beginning to form.Astronomers frequently observe "protoplanetary discs," which are discs of gas and dust that are the birthplaces of new planets, around such baby stars.But in order to observe the birth of these new "exoplanets," or extrasolar planets, astronomers had to detect protoplanetary disks earlier.Inside meteorites that have fallen to Earth, scientists can find a clue about what they should be searching for in these disks in their early stages. Meteorites are pieces of asteroids that formed during the formation of our solar system's planets 4.6 billion years ago. Meteorites, like those found in the protoplanetary disk around the sun during the early solar system, are rich in crystalline minerals that contain silicon monoxide, which condenses at high temperatures.The team found evidence of hot minerals condensing in the protoplanetary disk whirling around HOPS-315. They specifically found silicon monoxide in crystalline materials and as a gas surrounding this young star. This process has never been observed outside of our solar system or in a protoplanetary disk.Astronomers have discovered evidence that these hot minerals are starting to condense in the disc around HOPS-315. According to their findings, SiO is found both inside these crystalline minerals and surrounding the baby star in its gaseous state, indicating that it is only now starting to solidify. This process has never been observed outside of our Solar System or in a protoplanetary disc.By acting as a stand-in for young solar systems throughout the galaxy, the disc of HOPS-315 offers astronomers a fresh chance to investigate early planet formation and a fantastic analog for researching our own cosmic history.They discovered early signs of solid materials, which are the basic building blocks of planets.It helps scientists understand how planets like Earth might have formed billions of years ago.

Could This Be The End Of Cancer? Scientists Develop Revolutionary mRNA Vaccine
In a significant advancement in cancer research, scientists at the University of Florida have developed an experimental mRNA vaccine that enhances the body's immune response against tumours. The study, published in Nature Biomedical Engineering, shows that this vaccine, when combined with standard immunotherapy drugs known as immune checkpoint inhibitors, produced a strong antitumor effect in mice. What makes the finding especially promising is that the vaccine doesn't target specific tumour proteins. Instead, it activates the immune system as if it were fighting a virus. This effect was achieved by boosting the expression of a protein called PD-L1 within tumours, which made them more responsive to treatment. Lead researcher Dr. Elias Sayour, a paediatric oncologist at UF Health, said in a news release this discovery could lead to a new way of treating cancer without relying solely on surgery, radiation, or chemotherapy. The study was supported by the National Institutes of Health and other major institutions. If future studies in humans show similar results, the research could pave the way for a universal cancer vaccine that helps treat many types of difficult, treatment-resistant cancers. "This paper describes a very unexpected and exciting observation: that even a vaccine not specific to any particular tumor or virus - so long as it is an mRNA vaccine - could lead to tumor-specific effects," said Sayour, principal investigator at the RNA Engineering Laboratory within UF's Preston A. Wells Jr. Center for Brain Tumor Therapy. "This finding is a proof of concept that these vaccines potentially could be commercialized as universal cancer vaccines to sensitize the immune system against a patient's individual tumor," said Sayour, a McKnight Brain Institute investigator and co-leader of a program in immuno-oncology and microbiome research. Until now, there have been two main ideas in cancer-vaccine development: to find a specific target expressed in many people with cancer or to tailor a vaccine that is specific to targets expressed within a patient's own cancer. "This study suggests a third emerging paradigm," said Duane Mitchell, MD, PhD, a co-author of the paper. "What we found is by using a vaccine designed not to target cancer specifically but rather to stimulate a strong immunologic response, we could elicit a very strong anticancer reaction. And so this has significant potential to be broadly used across cancer patients, even possibly leading us to an off-the-shelf cancer vaccine." For more than eight years, Sayour has pioneered high-tech anticancer vaccines by combining lipid nanoparticles and mRNA. Short for messenger RNA, mRNA is found inside every cell, including tumour cells, and serves as a blueprint for protein production. This new study builds upon a breakthrough last year by Sayour's lab: In a first-ever human clinical trial, an mRNA vaccine quickly reprogrammed the immune system to attack glioblastoma, an aggressive brain tumour with a dismal prognosis. Among the most impressive findings in the four-patient trial was how quickly the new method, which used a "specific" or personalised vaccine made using a patient's own tumour cells, spurred a vigorous immune system response to reject the tumour. In the latest study, Sayour's research team adapted their technology to test a "generalised" mRNA vaccine, meaning it was not aimed at a specific virus or mutated cells of cancer but engineered simply to prompt a strong immune system response. The mRNA formulation was made similarly to the COVID-19 vaccines, rooted in similar technology, but wasn't aimed directly at the well-known spike protein of COVID.
