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.
Genetically modified organisms have almost become taboo in Europe. Elsewhere in the world, genetically modified plants are being cultivated on a large scale but public acceptance is far from being granted. How to deal with the people's reticence without taking extrem options, such as banning GMOs or ignoring the public outcry? A well-informed, serene debate is necessary. But is it still possible?
MEMS are to the world of smartphones and tablets what transistors were to consumer electronics in the 1960s. They're everywhere! A series of technological breakthroughs and industrial gambles paved the way to a flourishing market. An insight into this revolution by one its key players, STMicro's Benedetto Vigna.
African nations are seldom mentioned in the world ranking of innovative countries, but things could change with the rise of a new generation of technologies that perform many financial transactions from mobile phones. Today, mobile banking opens a new avenue for development. But can this model be exported?
The objective of the EU is to instate and implement a unified energy market by 2015. But opening markets and connecting grids may sound contradictory with unilateral decisions such as Germany's accelerated energy transition. Thus we see that there are two logics in Brussels, and with the increasing fraction and importance of renewables, they are now diverging more and more. It's time for the EU to look for technical as well as political solutions.
The myth of scientific management has all but disappeared, yet the industrial world continues to overvalue methods that have been standardized from outside the business environment, at the expense of creative solutions developed within companies themselves. Isn't it time to change the approach? Michel Berry, founder of the Paris School of Management, has long cultivated an attention to the singularity of situations. But how does one share the intelligence hidden in things singular? How should one train, transmit knowledge and exchange views? Envisioning management as an art overcomes these contradictions.
In the US, a disruptive new way for small companies to raise capital is putting a spotlight on the readiness of a tightly regulated securities market to adopt the openness of the Internet. It has sparked debate about whether the change will spur economic growth or become another vehicle for fraud.
Small modular reactors are seen as presenting a possible route to future nuclear power production, especially in developing countries. Some manufacturers even started to design subsea power stations. In terms of advantages, costs and risk management, it's a completely new equation.
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 the latest generation of connected objects, the collection of data related to our daily life has taken a new dimension. Covering surprisingly varied practices and objectives, from wellbeing to productivity and health, the notion of quantified self refers to the principles and tools developed to monitor, analyze and share these data. Another social thing? Call it a market.
Here we have yet another of those crazy ideas that excites California, but this one potentially sounds a shade more ominous. In order to meet the shortfall of qualified engineers in Silicon Valley, a group of young entrepreneurs of the Golden State have proposed to anchor a floating city in international waters, off the Californian coast, capable of accommodating 2 000 engineers from all round the world, none of whom having a US entry visa. This would cut the dire and endless thirst for grey matter in the USA, a country where young students are shunning scientific and technical courses. Here we are witnessing a situation that is taking on the proportions of a national, strategic crisis. Other countries, other difficulties. But eveywhere the same question arises: how to train tomorrow's engineers?
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.
Institutions, and not only technology, are a driver for change. In India, a recent experience shows promising and somehow unexpected outcomes. The goal? Ensuring greater transparency and competition in the award of government contracts. The result? Greater transparency, indeed; but also a new, efficient tool for conflict resolution.
Tablet sales showed their first sequential decline ever in the second quarter of this year, according to research firm IDC. Apple sold fewer iPads than expected in its most recent quarter. Barnes & Noble’s Nook e-reader sales fell 20% in the fiscal first quarter ended August 20, two months after the company announced it will no longer make color versions of Nook, only black and white ones. And analysts are worrying about whether smartphone profit margins can hold up as buyer fatigue sets in.
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.
Planned obsolescence has an infamous reputation: some denounce a crime against the environment, others, a swindle. A careful examination, however, shows that this business model is not all bad - and it even came to perform, during the Great Depression, as a miracle cure against the crisis!
What makes a great leader? The answer to this question has changed over time, as it refers to the way we form our representations of a company – a well conceived machine, a living body, a spirited team... Trends come and go, representations evolve, formulas change. Yet, the actual core of talent, or even the stroke of genius that makes a difference, seems to escape these formulas. So are management sciences condemned to mere prattle?
Up to 2008, the media have been relatively quiet about food security. However, this topic is resurfacing as a key issue. Financial markets disorders have unveiled underlying tensions: pressures on resources, inequalities in their access, as well as the effects of rapid growth of emerging countries. Today's pressures foreshadow tomorrow's tensions. Can we control these factors? And how?
Disruptive technologies have given the old science of onomastics unprecedented powers. Combined with datamining, extracting semantics from names can provide numerous, valuable applications. Though discriminating names carries a high risk of abuse, it can also drive new, unexpected ways for developing poor areas.
