Shape-shifting mobile devices

Researchers at University of Bristol unveil prototype mobile devices that can change shape on-demand, introducing the concept of 'shape resolution' and its ten features. The devices, called Morphees, can transform into different shapes to support various services and applications.

Conversion from bad fat to good fat

Scientists at ETH Zurich demonstrated that white and brown fat cells can convert into each other, challenging current beliefs. This interconversion process is likely to occur in humans as well, offering a novel strategy for treating obesity by promoting brown fat formation.

Dark field imaging of rattle-type silica nanorattles coated gold nanoparticles in vitro and in vivo

A new composite nanoparticle material, silica nanorattles @ gold nanoparticles (SN @ GNs), has been developed for biological imaging. The silica shell reduces the toxicity of gold nanoparticles, increasing their maximum tolerated dose to 200 mg/kg. This innovation provides a promising approach for cancer diagnosis and treatment.

Fish win fights on strength of personality

New research from the University of Exeter suggests that small fish with aggressive personalities are more likely to win food contests against larger, passive counterparts. The study found that consistently aggressive fish were able to put on weight and survive in resource-scarce environments.

Hitting 'reset' in protein synthesis restores myelination

Researchers at UB's Hunter James Kelly Research Institute have found that reducing a protein called Gadd34 can improve nerve and muscle function in patients with CMT neuropathies. By leaving protein synthesis partially off, they were able to restore myelination, potentially leading to new treatments for other misfolded protein diseases.

Exploring art at a stroke

The 'Repentir' smart phone and iPad app uses computer vision algorithms to reveal the multiple hidden stages of a painting. Users can explore the artist's creative process by rubbing away layers or scrolling through sequence images.

Researchers pinpoint how trees play role in smog production

New research reveals how trees produce particulate matter through the chemical reaction of isoprene with nitrogen oxides. This mechanism helps predict air quality episodes and impacts public health and climate change. Trees' natural defense against oxygen damage plays a surprising role in creating environmental concerns.

Tracking gunfire with a smartphone

Researchers at Vanderbilt University have developed a low-cost smartphone system that can track gunfire with remarkable accuracy, using unique sonic signatures produced by firearms. The system consists of an external sensor module and smartphones, working together to triangulate the origin of shots.

Weight loss programs via virtual reality

A new study published in the Journal of Nutrition Education and Behavior found that virtual reality weight loss programs can be an effective alternative to traditional face-to-face programs, with better maintenance rates. Researchers used Second Life, a web-based virtual reality environment, to deliver weight management education and t...

Are living liver donors at risk from life-threatening 'near-miss' events?

A recent study published in Liver Transplantation found that living liver donors experience a 0.2% mortality rate and life-threatening 'near-miss' events. Centers with more experience performing live donor procedures had lower rates of complications, suggesting the need for comprehensive information and education for donors.

Sexually explicit material affects behavior in young people less than thought

A recent survey of 4,600 young adults aged 15-25 found that 88% of males and 45% of females had consumed sexually explicit content in the past year. While there was a modest association between this behavior and sexual activities, other factors such as personal dispositions may play a more significant role in shaping their behaviors.

Study by Worcester Polytechnic Institute professor produces first edition of a bookworm's genome

Researchers at Worcester Polytechnic Institute have sequenced the genetic code of Panagrellus redivivus, a tiny nematode also known as the beer-mat worm. The study reveals nearly 24,000 putative genes and sheds light on animal biology, including differences between male and female organisms and unique adaptations of parasitic worms.
