Medical advancements and modern scientific techniques strive to solve challenges posed to human communities, especially healthcare threats. Viruses are one of the major threats and tend to make themselves resistant to drugs and evolve new mechanisms for survival by making subtle changes in their DNA called as mutations. Today among the many viruses, Dengue virus has been a serious problem causing mortality in widespread areas. Although treatments and drugs have been developed, it is essential to make sure that we’re ready to face worse cases in future.

Human beings, in their brief history, started off as hunter–gatherers hunting animals and birds, or collecting fruits and nuts to eat. They then invented agriculture, a revolutionary transformation from ‘collecting’ food to ‘growing’ it. Suddenly, acquiring food, which was one of the most important task of the early man, became a breeze. Today, in the era of technology, food production has reached new levels and so have our ways of handling the produce.

In July this year, the Moderate Resolution Imaging Spectroradiometer on NASA’s Aqua satellite photographed a major chunk of glacial ice shelf (5,800 sq. km) breaking off from one of Antarctica’s floating ice platforms, called Larsen C, shrinking its size by at least 10 percent.

In the present time, with increasing demand for transportation fuels coupled with declining reserves of crude oil, scientific communities are forced to focus on renewable fuels. Although biofuels obtained from energy crops such as food and non-food energy crops act as renewable fuels, various issues such as food versus fuel debate, biodiversity loss and their effect on the land has shifted the idea of energy production towards other alternative biofuel producers like waste materials and microorganisms.

Cancer, as a disease, is a puzzle on its own and scientists across the world are looking for hints from all sides to crack it. Now, what if previous research on cancer itself acts as a hint and guides new developments? That is exactly what scientists have done using bioinformatics. By scouting previous research on circulating tumour cells, scientists have identified the molecules responsible for metastasis in cancer. This discovery, they believe, can help not only in understanding the spread of cancer, but also in identifying new drug targets against the killer disease.

The need for effective and rapid bone regeneration treatments is crucial now more than ever, due to the ever-rising number of bone defects and fractures. Conventional bone regeneration like grafts suffer from a shortage of available donors as well as added complications due to the immune rejection of the grafts.

Within the body of any multicellular organism, including humans, there is a bustling array of cellular interactions happening at any given point of time. While there are many ways by which cells communicate with each other and other entities in the body, the underlying mechanisms of cellular communication remain fairly unique across species, organs and cells. One such mechanism utilizes the unique interaction between complex carbohydrates and cellular proteins as the “recognition software” for cells interacting with pathogens, toxins, and other cells.

Smart adaptive actuators are sought after for a variety of mechanical and aerospace applications. Commonly used piezoceramic and shape memory alloy actuators produce small displacements, and hence require motion amplification mechanisms. However, these mechanisms are prone to mechanical play, and are susceptible to wear and tear.

With the increasing use of electrical and electronic devices, the amount of ‘electronic waste’ that we generate is quickly filling up our landfills. Recycling electronic waste or e-waste is a challenge due to the emission of poisonous gases in the process. Now, a new study has designed various adsorbents to be used in the process of recycling by burning the e-waste. By using these adsorbents, the researchers hope, could make the whole process less toxic for the air and for ourselves.
