Almost every one of our body cells bears in its nucleus about 2 meters of DNA containing the genes that shape our being. All that, roughly 20.000 protein-coding genes, regulatory and unknown-function sequences, tightly packed inside a structure that has a volume of only a few cubic micrometres. How this huge amount of material is […]
Self-folding exoskeletons can help robots adapt for different missions Origami-like heat-activated exoskeletons can help robots adapt for varied missions by giving them the ability to roll, glide, walk and sail. Live Science Japan’s Akatsuki spacecraft collecting Venus climate data after rocky start After a difficult start, Japan has been collecting data about the harsh climate […]
There are plenty of examples of drugs that have been repurposed in recent years. For instance, thalidomide, the initially prescribed medication for headache in pregnant women which led to countless numbers of babies born with body malformations during the 50s and 60s, now this drug is used for treating certain types of cancer, such as […]
According to how the electronic band theory is usually explained, solids can be classified as insulators, semiconductors, or metals. But, actually, there is another kind of solid between semiconductors and metals, the semimetals. In insulators and semiconductors the filled valence band is separated from an empty conduction band by a band gap, in metals there […]
S tem cells can be cultured, multiplied and differentiated. By interacting with each other in this process of specialization they can follow organization programs that show striking similarities with what happens in the entire organism. This way you can form organoids —microscopic, yet primitively functional versions of livers, kidneys, hearts and brains grown from real […]
A long time ago, Aaron Burr Jr. (1756 –1836), the Vice-President of the United States under Thomas Jefferson said something that is still applicable today: “The rule of my life is to make business a pleasure, and pleasure my business”. This is because current society demands the same things as Burr society: good food, free […]
Specially engineered antibody blocks most HIV strains in monkeys A potent tri-specific antibody that targets nearly 100% of HIV strains and prevents infection in monkeys has been developed by National Institutes of Health scientists and pharmaceutical firm Sanofi. The antibody combo bolsters the immune system and blocks development of the virus. BBC Lager beer yeast […]
Something weird is happening in Mexico these days. Two powerful earthquakes have hit the country in two weeks. The second one occurred exactly on the same date of the thirty-second anniversary of the most damaging quake known in the country and the early warning system did not work properly. Even more: two hurricanes are causing […]
In 1882, Heinrich Hertz devoted himself to the study of electromagnetism, including the recent and still generally unappreciated work of Maxwell. Two years later he began his famous series of experiments with electromagnetic waves. During the course of this work, Hertz discovered the photoelectric effect, which has had a profound influence on modern physics. The […]
Recently a deal between the biopharmaceutical companies Gilead and Kite Pharma was announced. Under the agreement, Gilead will buy Kite for a stunning USD 11 billion, shifting the focus of Gilead from infectious diseases to the field of oncology, just like that. But why write a post on MI about such apparently business-related issue? Kite […]
