Like its human counterparts, a young star is cute but prone to temper flares-only a star's are lethal. A flare from a star can incinerate everything around it, including the atmospheres of any nearby planets starting to form.
Ribosomes are small "factories" in which proteins are assembled according to genetic construction plans. The maturation of ribosomes, of which every human cell contains up to a million, is a complicated, multi-phase process. Now, with the aid of cryo-electron microscopy, scientists from Heidelberg University and Ludwig-Maximilians-Universität München have been able to clarify an important step in ribosomal formation. These "protein factories" consist of two ribosomal subunits and the scientists have shown that the smaller one "peels out" of a precursor complex and does not break off en bloc, as was so far assumed. The findings were published in the journal "Science".
For much of Earth's four and a half billion years, the planet was barren and inhospitable; it wasn't until the world acquired its blanket of oxygen that multicellular life could really get going. But scientists are still trying to understand exactly how-and why-our planet got this beautifully oxygenated atmosphere.

The past 12 months have provided many eye-grabbing headlines from the Imperial community from world-leading research to incredible inventions. Before 2018 is upon us with its own wave of news, we take a quick look back at the most popular articles on our award-winning news site (ranked by the number of page views).
The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable sources. A promising new candidate is aluminium batteries, which are made from cheap and abundant raw materials. Scientists from Maksym Kovalenko's research group, which is based at both ETH Zurich and in Empa's Laboratory for Thin Films and Photovoltaics , are researching and developing batteries made from abundant raw materials.
Stanford political scientist Alison McQueen's research shows that apocalyptic rhetoric can make wars, natural disasters, economic collapse and even the possibility of nuclear war easier to understand. But although it can rouse people to action, apocalyptic rhetoric also carries great peril. Stanford political scientist Alison McQueen has studied the use of political rhetoric that evokes the end of the times, finding that it can comfort people during crises, making wars or economically troubled times, for instance, easier to understand.
Prof. Kiefer, what scientific topic are you working on right now? My group is investigating how lymphatic vessels form and how they are preserved in a functional state. During development, the lymphatic vessel system adopts a characteristic structure and we would like to understand, which molecular mechanisms are responsible for the formation of the prototypic shape of this vessel tree.
The white mouse has been anaesthetized. Its little legs have been affixed to a heating plate by means of adhesive strips, and a large amount of gel has been spread over its clean-shaven breast. An ultrasound probe is positioned overhead, and Richard Holtmeier, a member of the team at the European Institute for Molecular Imaging (EIMI) at the University of Münster is using this to study how the mouse copes with a plastic catheter which has been inserted into its carotid artery.
Bacteria not only develop resistance to antibiotics, they also can pick it up from their rivals. In a recent publication in "Cell Reports", Researchers from the Biozentrum of the University of Basel have demonstrated that some bacteria inject a toxic cocktail into their competitors causing cell lysis and death.
Harvesting energy from our movements and a method for determining the composition of cement were two of the most widely downloaded papers in 2017. Spiral - Imperial College London's open access repository - allows academics to make journal articles and other research outputs open access, meeting the requirements of the post-2014 Research Excellence Framework (REF).
What unites the needs of Ebola workers, people with multiple sclerosis and athletes comes down to one thing - cold hands. A device that cools the hands is finding widespread use from the playing field to the clinic. A cooling device that has been improving strength and endurance in mostly male athletes for 15 years is finding new uses in helping people with multiple sclerosis live normal lives, preventing overheating in Ebola workers and cooling working dogs.
Following years of research, AI is starting to have an impact on the way science is done, as these five Imperial studies from 2017 show. Barely a week has gone by in 2017 without warnings in the media about how Artificial intelligence (AI) and robotics is threatening to make all human workers redundant.
Coral reefs that can survive global warming, an expedition around Antarctica, a booster for genetic research, a personnal virtual heart, a National Center for Data Science... Some of the EPFL's research and milestones that marked the year 2017.
Last year Empa's inorganic analytics lab was granted the status of "Reference Laboratory" within the scope of the ProSUM project, funded by the EU. Fine-grained samples of shredder waste from scrapped cars, e-waste or mine dumps from all over Europe end up here. Empa chemists find out what is in them, what is worth extracting and what could be dangerous for staff at recycling plants.
An inability to focus the brain on tasks may partially explain why paralysis commonly occurs in people following a stroke, according to a news study. Patients who have suffered a stroke - where the blood flow to the brain is interrupted by a clot or bleed - often experience a degree of paralysis on one side of the body, termed hemiplegia, affecting the strength and dexterity in their limbs.
Biomedical engineering professor Kristyn Masters handles samples in her lab, where she and colleagues identified the early stages of a process that may eventually cause aortic stenosis, a severe narrowing of the aortic valve that reduces blood flow to the body and weakens the heart. (Photo by Stephanie Precourt) The diminutive size of our aortic valve - just shy of a quarter - belies its essential role in pushing oxygen-rich blood from the heart into the aorta, our body's largest vessel, and from there to all other organs.
When you enter a room, your brain is bombarded with sensory information. If the room is a place you know well, most of this information is already stored in long-term memory. However, if the room is unfamiliar to you, your brain creates a new memory of it almost immediately. MIT neuroscientists have now discovered how this occurs.
Some surprise research headlines need a second look, but quirky studies can often reveal serious science. From a geological Brexit to jellyfish computers, some research announcements are more than a little bit quirky. However, look beyond the headline and you'll find fascinating research with powerful real world applications.
Robotic prosthetics, AI guessing your brain age and much, much more. It's been quite a year for research, so here's just a few of the top stories... At times this year it may have seemed like science took a back seat, with politics bullying its way to the forefront and Brexit shoehorned into every headline to contend with.
Mark Schubert modifies wood properties with the aid of the enzyme laccase. However, the search for suitable ingredients is complex - a bit like trying to find the key to an unknown lock. Instead of long, expensive series of experiments, Schubert uses artificial intelligence as it gets him to the goal more quickly.
A new marker that could be used to diagnose fatal breast cancer up to one year ahead of current methods has been identified in a study led by UCL. The study, published in Genome Medicine today, found that changes detected in a part of DNA which the researches named EFC#93 could suggest early signs of deadly breast cancer.
Researchers from the University of Cambridge have taken a peek into the secretive domain of quantum mechanics. In a theoretical paper published in the journal Physical Review A , they have shown that the way that particles interact with their environment can be used to track quantum particles when they're not being observed, which had been thought to be impossible. We can verify old predictions of quantum mechanics, for example that particles can exist in different locations at the same time.
Introduction: Ben Van Duppen (University of Antwerp) and his international colleagues are paving the way for a successful internet of things. The ultra-thin material graphene can make the internet several thousand times faster. By cutting the material into very small strips, the researchers from several institutions, including the University of Antwerp, discovered a new effect that could give a strong boost to fibre internet.
