Scientists grow cartilage to reconstruct nose

Researchers at the University of Basel have developed a method to grow cartilage in the lab, enabling successful nose reconstruction surgery. The technique, known as tissue engineering, uses patients' own cells to create engineered cartilage that is implanted into the defect, resulting in improved functionality and cosmetic appearance.

Brainy courage of the rainbowfish

A study published in Springer's journal Behavioral Ecology and Sociobiology found that rainbowfish born in the wild are braver than those bred in captivity. The researchers suggest that fear is heightened when primarily processed by a single brain hemisphere, making lateralized fish less bold.

Experts disagree on horses with incoordination

Researchers from the University of Copenhagen found significant disagreement among experts about the severity of horse incoordination, also known as ataxia. The study aimed to establish clearer definitions for normal and abnormal gait patterns in horses, which could lead to greater agreement among specialists.

Identified epigenetic factors associated with an increased risk of developing cancer

Researchers have found epigenetic changes that increase the risk of developing cancer, which affect gene expression without altering the genes themselves. The study analyzed 3,500 tumors and identified genetic polymorphisms associated with an increased risk of cancer, highlighting DNA methylation as a key factor in the disease

Pseudo-mathematics and financial charlatanism

The article examines how backtesting can lead to overfitting, resulting in misleadingly good results that don't translate to real-world performance. Researchers argue that few companies and researchers conduct out-of-sample testing, leading to a lack of transparency in investment strategies.

New research on gigabit wireless communications

The study proposes enhanced technologies and algorithms to increase data capacity and densification in short-range wireless networks, achieving speeds of up to 7Gbps per link. Beamforming is also explored as a solution for multi-gigabit connections between base stations and users, with an adaptive algorithm reducing interference.

News from the Journal of Parenteral and Enteral Nutrition, April 2014

A.S.P.E.N. Clinical Guidelines developed recommendations for the care of pediatric patients with intestinal failure at risk of parenteral nutrition-associated liver disease, while a prospective observational study found that feeding interruptions led to negative outcomes in critically ill patients. Intensive nutrition therapy also show...

Thermoelectric generator on glass fabric for wearable electronic devices

KAIST researchers developed a flexible thermoelectric (TE) generator on glass fabric that produces electricity from human body heat, overcoming the limitations of existing TE generators. The new generator is extremely light, flexible, and compact, with a self-sustaining structure that eliminates thermal energy loss.

Uncovering a new angle on mental distance

A study published in Psychological Science found that people's orientation affects their perception of distance. The researchers discovered that moving in a certain direction makes places ahead feel nearer than those behind, regardless of actual distance. This phenomenon is linked to feelings of social similarity and emotional engagement.

Sunlight generates hydrogen in new porous silicon

Researchers at Penn State have developed a method to manufacture porous silicon using solar energy, which can generate hydrogen from water when exposed to sunlight. The material's high surface area and nanoscale size enable it to act as an effective catalyst, aiding in the production of hydrogen gas.
