Dynamical responses of heterogeneous materials are far from clear to scientists, although they are common phenomena in engineering applications. The research is rather challenging not only in physical modeling, but also in simulation technique and analyzing scheme.

Queen and worker ants develop from the same sets of genes, but perform completely different ecological roles. How the same genes result in two types of individuals is an ongoing mystery. In the past, scientists have only studied a small number of ant species at a time to try to understand the nature of queen-worker differences.

Researchers advise that this type of training, in spite of offering various neurological, metabolic and functional advantages, should be done in addition to a normal work out and not as a substitute

Practicing High Intensity Interval Training, or HIIT, together with integral electro-stimulation generates an up to 30% higher consumption of calories than conventional aerobic exercise.

CHAMPAIGN, Ill. -- Scientists have finalized a four-year study of newborn and fetal dolphins found stranded on beaches in the northern Gulf of Mexico between 2010 and 2013. Their study, reported in the journal Diseases of Aquatic Organisms, identified substantial differences between fetal and newborn dolphins found stranded inside and outside the areas affected by the 2010 Deepwater Horizon oil spill.

100-year-old persons in Germany are affected by substantial numbers of illnesses, and the frequency of untreated pain in this cohort is alarming. This is the result reported by Daniela Jopp and colleagues in their evaluation of the findings of the Second Heidelberg Centenarian Study in this issue of Deutsches Ärzteblatt International (Dtsch Arztbl Int; 2016; 113: 203-10).

When cells divide, the proper balance between the four DNA building blocks is required in order for the DNA to be copied without the introduction of potentially harmful mutations. Researchers at Umeå University in Sweden have now shown a connection between levels of DNA building blocks - dNTPs - and colon cancer. This discovery has been published in the Proceedings of the National Academy of Sciences.

Children of older mothers are healthier, taller and obtain more education than the children of younger mothers. The reason is that in industrialized countries educational opportunities are increasing, and people are getting healthier by the year. In other words, it pays off to be born later.

Neuherberg, April 12, 2016. The protein MALT1 is an important switch in immune cells and affects their activity. Researchers at Helmholtz Zentrum München report in Nature Communications that this activation is not always equally strong. Through alternative splicing, two variants of the protein may arise which have a stronger or weaker effect on the immune system. Understanding this process is important for the pharmacological use of MALT1.

UCLA biochemists have devised a clever way to make a variety of useful chemical compounds, which could lead to the production of biofuels and new pharmaceuticals.

Studies in a group of tropical birds have revealed one of the fastest limb muscles on record for any animal with a backbone. The muscle, which can move the wing at more than twice the speeds required for flying, has evolved in association with extravagant courtship displays that involve rapid limb movements, according to a paper to be published in the journal eLife.

A research team studying biodiversity at the Hannibal Bank Seamount off the coast of Panama has captured unique video of thousands of red crabs swarming in low-oxygen waters just above the seafloor.

Jesús Pineda, a biologist at Woods Hole Oceanographic Institution (WHOI) and chief scientist on the cruise, called the encounter unexpected and mesmerizing. The researchers describe their findings in a paper published April 12, 2016, in the journal PeerJ.

COLUMBUS, Ohio - There are six components to an apology - and the more of them you include when you say you're sorry, the more effective your apology will be, according to new research.

But if you're pressed for time or space, there are two elements that are the most critical to having your apology accepted.

"Apologies really do work, but you should make sure you hit as many of the six key components as possible," said Roy Lewicki, lead author of the study and professor emeritus of management and human resources at The Ohio State University's Fisher College of Business.

A team of scientists led by Oxford University have made a discovery that could improve our chances of developing an effective vaccine against Tuberculosis.

The researchers have identified new biomarkers for Tuberculosis (TB) which have shown for the first time why immunity from the widely used Bacillus Calmette-Guérin (BCG) vaccine is so variable. The biomarkers will also provide valuable clues to assess whether potential new vaccines could be effective.

Autonomous vehicles would have to be driven hundreds of millions of miles and, under some scenarios, hundreds of billions of miles to create enough data to clearly demonstrate their safety, according to a new RAND report.

Under even the most-aggressive test driving assumptions, it would take existing fleets of autonomous vehicles tens and even hundreds of years to log sufficient miles to adequately assess the safety of the vehicles when compared to human-driven vehicles, according to the analysis.

Lung ultrasound has been shown to be highly effective and safe for diagnosing pneumonia in children and a potential substitute for chest X-ray, according to a study conducted at the Icahn School of Medicine at Mount Sinai. Results are currently published in the medical journal Chest.
