Slow yoga prevents fainting

A randomized study found that guided yoga therapy was more effective in preventing fainting and improving quality of life compared to standard treatment. The study enrolled 100 patients with vasovagal syncope and found that the yoga group had fewer blackouts and better quality of life scores at 3, 6, and 12 months.

A new form of carbon

A team of researchers has discovered a new form of carbon that exhibits metallic properties, unlike graphene. The material, named Biphenylene network, is made by assembling carbon-containing molecules on an extremely smooth gold surface and has the potential to be used as conducting wires in future carbon-based electronic devices.

Soy kits provide earning power for women entrepreneurs in Malawi

A University of Illinois study reveals that soy kits can improve the economic conditions of Malawian women by creating value-added products from soy. The kits have potential to increase income generation and alleviate poverty, with gross margins averaging 56% and implicit wages estimated at $2 per hour.

Wireless and battery-free spintronic energy harvester

Researchers at Tohoku University and NUS developed an array of electrically connected spintronic devices that can harvest a 2.4 GHz wireless signal to power small electronic devices and sensors. The technology overcomes the challenge of synchronizing multiple magnetic tunnel junctions, enabling efficient energy harvesting.
