    There are strong political pressures to relax the scrutiny of suspected biological weapons activity in Iraq. But the experience of United Nations inspectors in the country points to significant dangers in such a policy.

    The experimental violation of Bell's inequalities confirms that a pair of entangled photons separated by hundreds of metres must be considered a single non-separable object — it is impossible to assign local physical reality to each photon.

    Trade in Arabian oryx, which are being poached from the wild and sold to illegally to private collectors, is threatening the long-standing oryx conservation project in Oman. Following a recent population crash caused by poaching, the project organizers have taken 40 animals back into captivity — where, if need be, they can form a breeding herd should wild oryx once again be wiped out in Oman.

    Telomeres have long been suspected to be involved in ageing, and we now have the first direct evidence. Transgenic mice were generated bearing a deletion in the mTR gene, which is an essential component of telomerase, the enzyme that maintains telomeres. After six generations of inbreeding, newborn mice show many of the physiological changes associated with normal — but aged — mice.

    Copper-oxide superconductors were discovered over a decade ago, but the high value of their superconducting transition temperature, Tc, has remained a mystery. A new tool for measuring the long-range phase coherence — essential for superconductivity — of high-Tc materials may provide a route to the answer.

    Maize was domesticated 7,500 years ago from the wild Mexican grass teosinte. Early farmers would have selected for certain characteristics, and for many years the genes that encode these traits have been sought. New insights into these genes come from an analysis of genetic variation in one of them, teosinte branched1, and the results bear on the question of exactly how maize was domesticated.

    Researchers met last month to discuss progress in the field of Bose-Einstein condensates -- a novel type of quantum matter discovered in 1995. Apart from devising a new technique to probe the nature of Bose-Einstein condensates, and developing 'atom optics', physicists are getting closer to creating a quantum Fermi gas.

    A functional canine bladder has been reconstructed from cells obtained by biopsy of the bladder wall. Cells from each side of the bladder wall were separately grown in culture, then seeded onto two sides of a bladder-shaped degradable polymer; the constructs were successfully implanted into dogs and continued to work like a real bladder for a year.

    Gravity waves — predicted by Einstein's general theory of relativity, but not yet detected — may one day reveal more about the very early Universe. They may also test theories of quantum gravity (the'unification' of quantum and gravitational forces), if a proposal to use gravity-wave detectors to probe the fuzziness of space-time becomes reality.

    One way to regulate the activity of transcription factors is to control the amount of time that they spend in the nucleus. This, in turn, can be modulated by exposing or blocking nuclear-localization and nuclear-export signals. A new regulatory mechanism is now proposed for a transcription factor called NF-AT4, and it seems that two other proteins, calcineurin and Crm1, compete for binding. The outcome of this battle determines whether an import or an export signal is uncovered.

    With the great whales in decline, the krill on which they feed will be more abundant than ever. To make use of this bounty, Daedalus plans a robot ‘oceanic filter feeder’. The plan is to allow a small proportion of the catch to decompose, which will provide methane to power the craft and (when reacted with carbon dioxide) will generate acetic acid to preserve the rest of the harvest.
