Across the developing world, seriously ill patients can't be sure whether they're purchasing life-saving medicines or worthless dummy pills. This scandal demands a stronger response from aid donors, governments and the drugs industry.
Across the developing world, people are dying after being peddled fake pharmaceuticals. Peter Aldhous reports from southeast Asia, where scientists, doctors and regulators battle against organized crime.
Dora Akunyili has spent the past four years facing down corruption and tackling Nigeria's rampant problems with fake drugs. This crusade has been phenomenally successful, but has placed Akunyili's life in danger. Peter Aldhous caught up with her on a recent trip to the United States.
A 62-million-year cycle in biodiversity emerges from scrutiny of a marine-fossil database, but its causes remain mysterious. Thus, this discovery is likely to provoke a flurry of theoretical speculation.
Is there an upper limit to the mass of a star? The answer to this long-standing question seems to be yes — and it has important consequences for our understanding of the evolution of galaxies.
Variations in the control of a phenomenon known as parental imprinting influence the likelihood of tumour development. These new findings may tie in with an earlier concept of ‘two-phase’ carcinogenesis.
Organic semiconducting polymers are promising electronic materials, but for full versatility they need to conduct negative as well as positive charge. A step towards that goal has now been taken.
The identity of the sperm molecules that are involved in fusion with an egg's membrane has eluded biologists. Will Izumo, a protein named after the Japanese shrine to marriage, bring harmony to the field?
The likely origin of Pluto and its satellite Charon, like the Earth and Moon, is an impact between two planet-sized bodies. Refined simulations show that there may be two distinct modes for the birth of such twins.
Claims that 3.8-billion-year-old rocks from Greenland contain carbonaceous remnants of very early life have been the subject of argument for several years. The latest analyses look like settling matters.
The addition of molecular biology to the existing range of imaging technologies is creating opportunities for scientists of many disciplines. Paul Smaglik lines up the pieces.
