Nano-sciences and nano-technologies are opening up hitherto unmapped paths to our bodies and health. But nano-medicine does not avoid the heated debates associated to this new scale. Risk assessment cannot be limited to a cost-benefit analysis. So, where do we go from here?
Robots will soon be able to read texts for us, engage in conversations, clean our windows, deliver packets and parcels, prepare our pill-boxes and even help us get back on our feet should we fall, or have difficulty just getting up. We had them first in the military sector, then carrying out industrial chores, now we see a new generation coming, prepared to do household chores, maintenance work, leisure activities or engage in educational activities. Whether they be macro-, or nano-, humanoid or dronoid, these robots are about to become our future companions. So, where do we stand today?
Today's researchers are enduring a tough period compared to other scientists throughout history. Due to funding and institutional constraints, they have to work on short-term contracts serving commercial interests and must make promises that they can hardly live up to. One example involves quantum computers. Scientists should devote themselves to basic research crucial to tackling long-term world issues, says Nobel Prize Serge Haroche. This does not prevent him from advocating a strong sense of humanity among scientists. He supports an ideal education and research system combining science and humanity that stokes people's curiosity and enthusiasm for science, while at the same time cultivating an atmosphere encouraging imagination and innovation.
Mathematical skills have become strategic for the business world and the most advanced companies hire high level scientists who tackle the underlying, fundamental, theoretical questions. However, this increasingly vital role of the boffins dedicated maths specialists often brings with it new demands and unforeseen responsibilities.
Initially developed for military uses, exoskeletons are now moving into civvy street, with applications under development for disabled senior citizens or handicapped persons. Business of this product calls for sophisticated technologies by also for a clear view at the end-users. In this technology-intensive, leading edge emerging market, start-ups are out front.
As of the early 2000's, Internet has opened paths to a new form of collective intelligence, human or humanoid computing. Be reassured, reader, this is not a way to turn your brain into a computer. What it does is coordinate thousands of connected people together to assemble a computer power that exceeds, for certain complex problems, what is already available today via supercomputers. The specialty biochemistry was first on the track, and now we see financial affairs joining in. So, let's see what happens when amateurs take over a market trading room.
Rapid advances in neurosciences have led to some decisive progress in fields as varied as education, or treatment of psychiatric disorders. But it is a specialty where debate rages as the ambitions expand overtly.
Significant tech breakthroughs, a growing number of applications, mature industrial processes: in recent years many factors have boosted the development of nuclear medicine. Not so long ago, it was a matter of R&D. Now it's an industry. One of its most interesting business lines is the production of FDG, the most widely used radioactive tracer in nuclear medical imaging.
Burning of fossil fuels constitutes the main source today of greenhouse gases. It is also the principal vector of anthropic action on the climate. But the relationship between energy and climate is far more complex that it seems initially. Scientific knowledge is advancing constantly and what is now noteworthy is that the players, whether they are private individuals, national and local authorities or business companies are becoming increasingly aware of the challenges that lie ahead. Where does science stand today and how can we use the available knowledge?
Various technologies are now vying to develop an augmented human being. Step-by-step, they would gradually modify the basic data registers of life, such as intelligence, procreation, ageing. Techno-prophets, not all crazed illuminati, entertain the dream of the advent of New Mankind. Major (and some minor) ethical questions arise as we explore a phenomenon that is no longer restrained within the wraps of sci-fi.
The spectacular optical properties of nanoparticles are revolutionizing medical imaging. They also help to renew therapeutic techniques. On the occasion of the inauguration of the AXA-ESPCI Chair, Emmanuel Fort, professor at the Langevin Institute of ESPCI ParisTech, presented the latest advances in a promising field where two roads meet.
Advances in neuroscience have shed a new light on our understanding of classic issues about learning. How does it work? Is it different for adults and children? During a recent lecture, Stanislas Dehaene, a neuroscience researcher, gave an overview of recent discoveries in this field. A revolution in the making.
With 3-D medical imaging rapidly coming on line, a silent revolution is under way in our hospitals and research establishments. Practitioner's techniques are constantly improving and gaining ground, but there are limits. New strides forward will come from combinatory techologies, for example, by marrying PET-Scan and MRI.
Ecologically speaking, coal is the worst energy source around. But it nonetheless possesses some almost irresistible features. It is still abundant, easy and cheap to mine. Promising technologies could allow cleaner, healthier ways to burn it. Let's have a look.
Ever since the electronic properties of silicon were discovered in the United States in the late 30s, it has been a well-known fact: a new material can change the world. Perhaps because it weighs less, is sturdier, provides better thermal and acoustic performance, lasts longer, or makes production and assembly easier. Every now and then, the scientific community announces a new miracle material successor to silicon and the 2010s already rustle with announcements about a very serious candidate: graphene, a two-dimensional crystal consisting of a single layer of carbon atoms, which is credited with exceptional potential.
How do financial mathematics specialists imagine the markets in five to ten years? What exactly will their role look like? To understand these issues, we need to take a closer look at the way this field has developed and at the issues that have shaped the discipline.
The venture investor and former Facebook executive examines technologies he thinks will improve the quality of life and economic output, and explains why most executives undervalue technical proficiency.
As well as androids they are our self-guided vacuum-cleaners, our GPS, an automated line on the Paris metro linking two of the city's main underground stations, Internet search engines… From mechanized figurines to the first robot arm, a brief journey through a history 3000 years in the making.
Microfluidics is the science of how we analyse and handle fluids at a micrometric level. MIT's Technology Review regularly cites this technology as being one that could change the world. Why?
Cancer diagnosis and treatments today are undergoing deep-reaching changes. Therapeutic strategies, until recently, could be summarised as ablation of the diseased organs and destruction of cancerous cells, often leading to serious unwanted effects that weaken the patient or limit the efficiency of the cancer treatment. But innovative approaches are emerging. They target cell functions and its close environment.
