Watch origami ‘metabot’ twist and expand without power

1 day ago | cosmosmagazine.com | Imma Perfetto

The fascinating behaviour of origami has inspired engineers to design a structure that twists when compressed and shrinks when twisted. The structure is a “metamaterial”; a class of engineered materials that exhibit behaviour not seen in nature and whose properties depend on their structure rather than chemical composition. These materials can have applications ranging from heat regulation to robotics and packaging.
Science uncovers key to success of Gout Gout

6 days ago | thenewdaily.com.au | Imma Perfetto

Australia’s 17-year-old sprinting sensation Gout Gout has blitzed yet another milestone on his way to global domination. Gout clocked in at 19.84 seconds to win the men’s 200-metre final at the Australian Athletics Championships in Perth last weekend. The effort would have secured the Queensland teenager a record, but for an illegal wind speed of 2.2 metres a second.
Blood supply will be another victim of the climate crisis

1 week ago | cosmosmagazine.com | Imma Perfetto

Climate change will impact all aspects of life as we know it, including blood donation with a new review in The Lancet Planetary Health now suggesting that climate change poses serious risks to the safety, stability, and availability of the global blood supply.

Gout Gout, the seventeen-year-old sprinting prodigy from Australia, has blitzed yet another milestone on his way to global domination. Gout clocked in at 19.84 seconds to win the men’s 200m final at the Australian Athletics Championships in Perth this past weekend. The effort would have secured him a new record, but for an illegal wind speed of 2.2m per second.
the next step in medical diagnostics

1 week ago | cosmosmagazine.com | Imma Perfetto

Imagine standing in your kitchen at home, feeling a little off colour. You grab a handheld device from the medicine cabinet and breathe into it, looking for an instant diagnosis of whatever you’re coming down with. Such a machine is being developed right now, using technology called optical frequency combs. Or just combs.
Researchers trace unusual source of recent cholera outbreak

1 week ago | cosmosmagazine.com | Imma Perfetto

Imported “holy water” has been identified as the culprit behind multiple cholera outbreaks which were identified in Germany and the UK in February, and which landed 3 people in hospital with 1 in intensive care. Genetic testing revealed the water was contaminated with a multidrug-resistant strain of the Vibrio cholerae, according to a new study in the peer-reviewed scientific journal Eurosurveillance which identified the source and most likely route of transmission.
India's local climate predicts deadly snake's venom

1 week ago | cosmosmagazine.com | Imma Perfetto

In India, the snakebite capital of the world where about half of all snakebite deaths occur, a single deadly serpent causes more death and disability than any other. Russell’s viper (Daboia russelii) is found across the Indian subcontinent, but its venom varies wildly between regions. This means that a person bitten in one place will experience different symptoms to someone bitten elsewhere.
Salmon on benzos warn of pharmaceutical pollution's impacts

1 week ago | cosmosmagazine.com | Imma Perfetto

While modern medicine allows us to manage or cure previously untreatable diseases and conditions, pharmaceuticals and their metabolites have untold consequences when they make their way into the environment.
Milky Way’s neighbouring galaxy could be ripped apart

2 weeks ago | cosmosmagazine.com | Imma Perfetto

Large galaxies like our own, the Milky Way, are often orbited by smaller satellite galaxies that buzz about like bees around a hive. The Small Magellanic Cloud (SMC) and its larger companion, the Large Magellanic Cloud (LMC), are some of our closest dwarf galaxies. They can even be seen with the naked eye in the southern hemisphere at night. But new research from Japan suggests that the gravitational pull of the LMC might be tearing the smaller one apart.
Watch this tiny robot hop like a pogo stick

2 weeks ago | cosmosmagazine.com | Imma Perfetto

Jumping on a pogo stick isn’t as easy as it looks, and it looks quite difficult to begin with. But robotics engineers seem to have identified the issues to create a hopping robot. Their robot, which is smaller than a human thumb, can bound across ice, wet surfaces, and uneven soil. It can even hop around on a dynamically tilting surface.
