Long-term follow-up of risk of cancer among twins

In a long-term follow-up study among approximately 200,000 Nordic twin individuals, there was an increased cancer risk in twins whose co-twin was diagnosed with cancer, with an increased risk for cancer overall and for specific types of cancer, including prostate, melanoma, breast, ovary, and uterus, according to a study in the Jan. 5, 2016 issue of JAMA.

Exercise and diet improves ability to exercise for patients with common type of heart failure

Among obese older patients with a common type of heart failure, calorie restriction or aerobic exercise training improved their ability to exercise without experiencing shortness of breath, although neither intervention had a significant effect on a measure of quality of life, according to a study in the Jan. 5, 2016 issue of JAMA.

Researchers report the development of nanoparticles made from repetitively branched molecules that could effectively deliver small RNAs to liver cancer cells with low toxicity to normal tissue, and that extended survival by up to 40 days when used in conjunction with a tumor-suppressing microRNA in a mouse model of aggressive, late-stage liver cancer.

Conflict and social influence

Researchers report that a social network-based intervention reduced student conflict in schools. Student conflict, particularly bullying, has recently received a surge in research and policy attention, yet there is little evidence to suggest that current interventions have been effective at reducing conflict.

How epigenetics can affect ants’ behavior

By applying compounds that cause epigenetic changes to ants, researchers were able to change the insects’ behavior. Epigenetics is a process where environmental factors switch genes 'on' and 'off', and results by Daniel Simola et al. demonstrate how this can have lasting effects on behavior.

Scientists Variable vectoring technique for propeller powered unmanned aerial vehicles

The maneuverability of unmanned aerial vehicles can be greatly enhanced through the use of variable vectoring technique. The current research developed a novel variable thrust direction mechanism, which provides the normal propeller UAV with the capability of directional force control. The newly developed VTD UAV was applied to implement plateau missions, which demonstrates the usefulness of the proposed technique.
