3-D-printed objects connect to WiFi without electronics

Top Story Imagine a bottle of laundry detergent that can sense when you’re running low on soap — and automatically connects to the internet to place an order for more. Researchers are making this a reality by 3-D-printing plastic objects and sensors that can collect useful data and communicate with other WiFi-connected devices entirely on […]

Nature's toughest substances decoded

Nature's toughest substances decoded

Top Story How a material breaks may be the most important property to consider when designing layered composites that mimic those found in nature. A new method decodes the interactions between materials and the structures they form and can help maximize their strength, toughness, stiffness and fracture strain. Scientists and engineers have worked for years […]

Engineers 3-D print a 'living tattoo'

Top Story Engineers have devised a 3-D printing technique that uses a new kind of ink made from genetically programmed living cells. The cells are engineered to light up in response to a variety of stimuli. When mixed with a slurry of hydrogel and nutrients, the cells can be printed, layer by layer, to form […]

Scorching hot springs house extreme life and a future ocean

Luca Marziale www.lucamarziale.com By Alice Klein SCORCHING temperatures, salt-smothered terrain and toxic air. It doesn’t sound like an inviting place to live, yet here in the Danakil depression in Ethiopia, microorganisms are thriving. The harsh environment sits at the Afar triangle, where three tectonic plates are gradually pulling apart. As the ground splits open, geothermally […]

Sumatran tigers fall 17 per cent and have just two strongholds

A male Sumatran tiger in Bukit Barisan Selatan National ParkMatthew Scott Luskin By Aylin Woodward Sumatran tigers are running out of places to live. Their population fell by 16.6 per cent between 2000 and 2012, and the remaining tigers are trapped in shrinking forests. “We’re really at a tipping point in terms of how much […]

Researchers develop graphene nano 'tweezers' that can grab individual biomolecules

[unable to retrieve full-text content] Full Text: Researchers have found yet another remarkable use for the wonder material graphene — tiny electronic “tweezers” that can grab biomolecules floating in water with incredible efficiency. This capability could lead to a revolutionary handheld disease diagnostic system that could be run on a smartphone. Graphene, a material made […]

Antiaging protein could be targeted to rejuvenate immune cells

Antiaging protein could be targeted to rejuvenate immune cells

Top Story Antiaging proteins have long been shown to protect against age-related diseases, such as cancer, neurodegeneration and cardiovascular disease. A study now reveals that one such protein could also be targeted to rejuvenate cells in the immune system. The protein in question is called SIRT1, more commonly known for being activated by red wine. […]
