    How smart are you? Artificial intelligence can tell based on your Twitter feed

    A new machine learning algorithm could predict studentsโ€™ academic performance based on the length and quality of their social media posts, with potential to uncover previously overlooked factors contributing to learning outcomes. It might even find applications in social research far beyond the domain of education. The algorithm was developed by Ivan Smirnov, leading research…

    Seรกn Dunphy discusses recent developments in COVID-19 vaccines.  Vaccine development is complex and often takes 10 to 15 years of research. With this in mind the scientific response to the Covid-19 pandemic is remarkable. In a single year, 54 Covid-19 vaccines have been brought to human trials, and 13 of these are in the final…

    Dorothy Crowfoot Hodgkin (1910-1994) was the 1964 Nobel Prize laureate in Chemistry, and the first and only British woman to obtain a Nobel Prize in Science. The prize was awarded “for her determinations by X-ray techniques of the structures of important biochemical substances”, including vitamin B12, insulin, penicillin, and vitamin D. This enabled them to…

    Ellie Bennett uses neuroscience to explore what has gone wrong in the zombie brain to make them the lumbering, flesh-hungry creatures depicted on our screens.ย  A lumbering gait, no recognition of loved ones, the inability to verbalise above moans and grunts, and an insatiable appetite. Itโ€™s the archetypal zombie. Heโ€™s been staggering his way through…

    One of the greatest challenges limiting our ability to send astronauts on long-haul missions is the need for constant resupply of essential materials from Earth. Any manned spaceflight needs to carry enough food, water and oxygen to sustain a crew for the duration of the mission, but there is only so much weight a single…

    Fear as an emotion is universal; whether it be the fear of the dark, spiders, or heights. This intense, emotional reaction to a perceived threat infects the minds of many.
