Unexpected insights into early dinosaur’s brain, eating habits and agility
A pioneering reconstruction of the brain belonging to one of the earliest dinosaurs to roam the Earth has shed new light on its possible diet and ability to move fast. Research, led by the University of Bristol, used advanced imaging and 3-D modelling techniques to digitally rebuild the brain of Thecodontosaurus , better known as the Bristol dinosaur due to its origins in the UK city.

Bacterial nanopores open the future of data storage
Bioengineers at EPFL have developed a nanopore-based system that can read data encoded into synthetic macromolecules with higher accuracy and resolution than similar methods on the market. The system is also potentially cheaper and longer-lasting, and overcomes limitations that prevent us from moving away from conventional data storage devices that are rapidly maxing out in capacity and endurance.

Researchers identify the origin of a deadly brain cancer
Finding could lead to potential therapies Researchers at McGill University are hopeful that the identification of the origin and a specific gene needed for tumour growth could lead to new therapeutics to treat a deadly brain cancer that arises in teens and young adults. The discovery relates to a subgroup of glioblastoma, a rare but aggressive form of cancer that typically proves fatal within three years of onset.

Neuroscientists tap gamers to learn how people problem-solve
The game app hexxed may cast a spell on players who have to figure out the rules of the game and what the goal is. Neuroscientists hope to use player strategies to understand how people solve problems compared to how artificial intelligence solves problems. Fans of Candy Crush Saga, Flow Free or Minesweeper should check out a challenging new mobile game app, hexxed , that will stretch your brain as it helps brain researchers understand human strategic thinking and perhaps improve the reasoning of artificial intelligence.

'Boss' genes could save human hearts - and the reef
’Boss’ genes could save human hearts - and the reef
The chain of command inside human cells is similar to the way a factory is run, two University of Queensland researchers say. But Dr Nathan Palpant and Associate Professor Mikael Boden 's big news is that they have found the password to the chief executive's computer - metaphorically speaking. "We discovered a simple but powerful rule revealing how cells are controlled by rare decision-making genes,' said Dr Palpant, from UQ's Institute for Molecular Bioscience.

Gene could help predict response to cervical cancer treatment
FINDINGS UCLA researchers have identified a potential diagnostic marker that could help predict how likely someone with cervical cancer is to respond to the standard treatment of chemotherapy and radiation. The scientists found that PACS-1, a gene that resides on a small segment of the long arm of chromosome 11, is overexpressed in cancer tissues, which can result in cancer growth and spread.

Tagging, recording and replaying neural activity
An interdisciplinary team of scientists has created a new molecular tool to help us better understand the cellular basis of behavior. A new molecular probe from Stanford University could help reveal how our brains think and remember. This tool, called Fast Light and Calcium-Regulated Expression or FLiCRE (pronounced "flicker"), can be sent inside any cell to perform a variety of research tasks, including tagging, recording and controlling cellular functions.

Vitamin D the clue to more autism spectrum disorder in boys
A deficiency in vitamin D on the mother's side could explain why autism spectrum disorder (ASD) is three times more common in boys, say researchers from The University of Queensland. In their latest study, Professor Darryl Eyles and Dr Asad Ali from UQ's Queensland Brain Institute found vitamin D deficiency during pregnancy caused an increase in testosterone in the developing brain of male rats.

Using CRISPR, new technique makes it easy to map genetic networks
The CRISPR-Cas9 protein (above) allows researchers to inactivate individual genes in the genome, using a guide RNA sequence that matches the target gene. These guide RNAs are paired with nucleotide barcodes in a new and fast technique to map genetic networks called CRISPR interference with barcoded expression reporter sequencing, or CiBER-seq.

Testing memory over four weeks could predict Alzheimer’s disease risk
New research suggests testing people's memory over four weeks could identify who is at higher risk of developing Alzheimer's disease before it has developed. Importantly, the trial found testing people's ability to retain memories for longer time periods could predict this more accurately than classic memory tests, which test memory over half an hour.

Bacteria release climate-damaging carbon from thawing permafrost
A new study based on scientific sampling of a rusty carbon sink at a permafrost peatland at Sweden has revealed that iron minerals fail to trap organic carbon, a vast source of CO2 and methane not included in global warming forecasts. The study, conducted by researchers from the Universities of Tübingen and Bristol conducted their investigation site at Stordalen mire, Abisko, Sweden appears today [10 December].

Gene therapy injection in one eye surprises scientists by improving vision in both
Injecting a gene therapy vector into one eye of someone suffering from  LHON , the most common cause of mitochondrial blindness, significantly improves vision in both eyes, scientists have found. Saving sight with gene therapy is now a reality Patrick Yu-Wai-Man In a landmark phase 3 clinical trial, the international team, coordinated by Dr Patrick Yu-Wai-Man from the University of Cambridge and Dr José-Alain Sahel from the University of Pittsburgh and Institut de la Vision, Paris, successfully treated 37 patients suffering from Leber hereditary optic neuropathy (LHON) .

DeepLabCut-Live! real-time marker-less motion capture for animals
Behavioral scientists at EPFL introduce DeepLabCut-Live!, a deep-learning tool that can enable real-time feedback studies on animal movement and posture. The software features "maker-less" real-time motion capture, can interface with lab hardware for neurological analysis, and is now available open source for use by researchers.

Cancer Research in Bern: Analysing and finding solutions to treatment resistance
A number of types of cancer are prone to adapt to targeted treatment, enabling resistance. Prof. Mark Rubin, Department for BioMedical Research and Bern Center for Precision Medicine, together with colleagues from the Weill Cornell Medicine and the University of Manchester have now published a 'Perspective' in the journal Molecular Cell.

How soil fungi respond to wildfire
How soil fungi respond to wildfire
When wildfires swept through the North Bay in 2017, graduate student Gabriel Smith saw a unique opportunity to study how fire affected his research subject: soil fungi. In the wake of the 2017 North Bay fires, the golden hills of Santa Rosa, California, were unrecognizable. Smoky, seared and buried under ash, the landscape appeared desolate, save for some ghostly, blackened - but still alive - oak trees.

Lung bacteria defend against pneumonia
Lung bacteria defend against pneumonia
Commensal bacteria confer a prominent protective role against invading bacterial in mucosal surfaces, the major entry port for microbial pathogens. A research team of UNIGE shows that probiotics could be an alternative to antibiotics for treating respiratory illnesses. In healthy organisms, commensal bacteria, which live inside the host without harming it, provide a competitive barrier against invading bacterial pathogens.

Magnetic bacteria as micropumps
Magnetic bacteria as micropumps
Scientists use magnetic bacteria to control liquids at the micro level. They are already thinking about using them in the human bloodstream for precision delivery of cancer drugs to a tumour. Cancer drugs have side effects, so for many years, scientists have been exploring ways to transport the active substances to a tumour in the body as precisely as possible.

Genetics of human face begin to reveal underlying profile
Genetics of human face begin to reveal underlying profile
In an international study led by KU Leuven and Pennsylvania State University, researchers have identified 203 genes that play a role in the shape of our face. Their study was published. The genetics behind the shape of the human face are difficult to decipher. In 2018, KU Leuven Professor Peter Claes and international colleagues, from Penn State, the University of Pittsburgh and Stanford University School of Medicine, already identified 15 genes that can be connected with specific areas of the face.
