Artificial muscle’ takes origami to the next level
Imagine an electrically-powered device as thin as paper, as powerful as human muscle, and capable of lifting 1,000 times its own weight. Researchers from the University of Bristol have done precisely that, creating an artificial 'muscle' that could boost the power of anything from microrobots to space structures.

The age of the water in the world's oceans is critical for understanding ocean circulation, especially for the transport of gases from the atmosphere into the deep ocean. Researchers from Heidelberg University recently used an atomic physics technique they developed to determine the age of deep ocean water ranging from 50 to 1,000 years.
Experimental Alzheimer’s drug improves memory in mice
Health + Behavior UCLA RESEARCH ALERT Sarah C.P. Williams FINDINGS An experimental drug known as A03, which was previously developed to treat depression, increases the levels of the enzyme Sirtuin1, or SirT1, and improves memory in mice. The mice were genetically modified to have a protein called ApoE4, the most common genetic risk factor for Alzheimer's disease in humans that has been linked to some forms of the disease.

A new study from The Australian National University (ANU) has uncovered some alarming trends when it comes to obesity rates amongst children of Australian immigrants. PhD candidate Tehzeeb Zulfiqar looked at data for thousands of Australian children, aged from four to 11. She found children whose mothers were born in low or middle income countries are more likely to be overweight or obese than children whose mothers come from wealthier countries like Australia.
Sulfate Helps Plants Cope With Water Scarcity
Plants absorb the mineral sulfate from groundwater. An international research team led by scientists from Heidelberg University has uncovered how sulfate controls the production of the drought stress hormone ABA in plants and thus contributes to their drought-resistance. These findings improve scientists' understanding of how the drought-stress signal travels from the roots to the leaves.

The number of people living with dementia globally more than doubled between 1990 and 2016 from 20.2 million to 43.8 million, prompting researchers to call for more preventative action. A new paper published in The Lancet Neurology also found that 22.3 per cent of healthy years lost due to dementia in 2016 were due to modifiable risk factors.
Artificial intelligence and extensive satellite imagery have allowed researchers to map the world's intertidal zones for the first time, revealing a significant loss of the crucial ecosystem. The University of Queensland and University of New South Wales study has shown that global foreshore environments declined by up to 16 per cent between 1984 and 2016.
Cambridge experiment with City of London police found that, while rarely deployed, just the presence of electroshock devices led to greater overall hostility in police-public interactions - an example of what researchers call the 'weapons effect'. The presence of Tasers appears to provoke a pattern where suspects become more aggressive toward officers, who in turn respond more forcefully Barak Ariel A new study has found that London police officers visibly armed with electroshock 'Taser' weapons used force 48% more often, and were more likely to be assaulted, than those on unarmed shifts.
3D-printed robot hand ’plays’ the piano
Scientists have developed a 3D-printed robotic hand which can play simple musical phrases on the piano by just moving its wrist. And while the robot is no virtuoso, it demonstrates just how challenging it is to replicate all the abilities of a human hand, and how much complex movement can still be achieved through design.

Robots invaded the Sahara Desert for Europe's largest rover field test, taking place in a Mars-like part of Morocco. For two weeks three rovers and more than 40 engineers performed testing of automated navigation systems at up to five different sites. This marked the end of the first phase of the strategic research cluster on space robotics technologies, a scheme funded by the European Union's Horizon 2020 programme.

Scientists build flashlights to peek inside the ’garbage disposal’ of cells
Big Brains Podcast Climate change's human cost with Michael Greenstone The story of the lysosome is a classic smear campaign. Once dismissed as the garbage disposal of the cell-it does break down unneeded cell debris-it is now valued by scientists who realized all that dirty work also controls survival, metabolism, longevity and even neurodegenerative diseases.

Move over Mona Lisa , here comes tic-tac-toe. It was just about a year ago that Caltech scientists in the laboratory of Lulu Qian , assistant professor of bioengineering, announced they had used a technique known as DNA origami to create tiles that could be designed to self-assemble into larger nanostructures that carry predesigned patterns.
Quicker, safer test could accurately detect some bowel cancers
Patients with suspected bowel cancer could be offered a quicker test to assess their cancer risk. This is the finding of new research from Imperial College London. The study, which tracked 7375 patients referred to hospital with suspected bowel cancer, compared two methods of examining the inside of the bowel - whole colon investigation and flexible sigmoidoscopy.

Chemists synthesise molecule as possible component for quantum computers Light PhD candidate Benjamin Kintzel (l.) and Winfried Plass discuss a molecule they have developed, that may possibly be used in a quantum computer.

Inventory indicates who goes solar and why
Stanford researchers have identified the GPS locations and sizes of almost all U.S. solar power installations from a billion images. Using the data, which are public, they identified factors that promote the use of solar energy and those that discourage it. Knowing which Americans have installed solar panels on their roofs and why they did so would be enormously useful for managing the changing U.S. electricity system and to understanding the barriers to greater use of renewable resources.

From eyedrops to potential leukaemia treatment
An active ingredient in eye drops that were being developed by experts in Nottingham has shown promise for treating an aggressive form of blood cancer, research has shown. Researchers from the University of Nottingham worked on the research led by scientists at the Wellcome Sanger Institute, University of Cambridge, and other collaborators which found that the compound, which targets an essential cancer gene, could kill leukaemia cells without harming non-leukemic blood cells.

Scientists break new ground in potential treatment of common form of leukaemia
Scientists at the University of Glasgow have discovered a potential combination therapy for the treatment of chronic lymphocytic leukaemia (CLL), the most common form of leukaemia in the Western world, diagnosed in more than 3,500 people in the UK each year. The research, carried out in collaboration with NHS Greater Glasgow and Clyde (NHSGGC) and published in Clinical Cancer Research , found that the combination of ibrutinib, a targeted treatment already in clinical use, with a new inhibitor called AZD8055, helped promote CLL cell death in a preclinical study.

In speech and music, words and notes depend on each other. Humans are highly sensitive to such dependencies, but the evolutionary origins of this capacity are poorly understood. Cognitive biologists at the University of Vienna conducted playback experiments with common marmoset monkeys and found that sensitivity to dependencies might have been present in the shared ancestor of marmosets and humans.
