    • "Even though we'll know that, at Saturn, Cassini has already met its fate, its mission isn't truly over for us on Earth as long as we're still receiving its signal."
    • "That's where water, because the Sun hardly shines there, should be frozen solid and you have to have liquid water to be able to have life.
    • "And now we're finding whole moons with oceans of liquid water that have been that way for 4.5 billion years.
    • BBC News will have live coverage of the ending of the mission on both TV and radio.
    • This is being repeated on Thursday on BBC Four at 19:30 BST. Jonathan.AmosINTERNET@bbc.co.uk and follow me on Twitter: @BBCAmos

    • A team in China has unpicked the genetic blueprint of an orchid that grows wild in the mountains of southeast China.
    • Researchers led by the Orchid Conservation and Research Centre of Shenzhen sequenced the genome of the orchid and compared it with more modern species.
    • "Whether you're looking at a big, blousy Moth orchid from the supermarket or a tiny rare Bog orchid on a remote Snowdonia hillside, the flowers have the same underlying blueprint," he said.
    • Some of the unique features of orchids include masses of pollen, known as pollonia, exceptionally light seeds and the ability to grow upon other plants, using them for support.
    • All these features are found in the 50 or more species of wild, native orchids in the UK, from the Lady'sslipper orchid to the Bog orchid.

    • Queen's University Belfast scientists have designed a new flexible organic battery that could revolutionise how medical implants are powered.
    • As it is decomposable, the organic battery is also expected to have environmental benefits.
    • "Everyone wants to go lightweight and everyone wants to be flexible," Dr Srinivasan said.
    • "If the battery goes flexible the whole electronics and equipment can go flexible, it's interesting and exciting."
    • While current batteries contain toxic materials that are complicated to recycle, organic batteries would simply decompose over time.

    • The combination of a warm, dry spring, followed by July and August rains, has led to a plethora of berries, according to horticulturalists.
    • Plants that are already bearing berries include spindle bushes (Euonymus) and firethorn (Pyracantha), while crab apples are also ripening early.
    • The fruits are likely to coincide with the appearance of autumn colour on leaves.
    • The dry warm spring encouraged pollinating bees, wasps and flies to be out at peak flowering times in April and May.
    • Then, the warm, wet summer was perfect for fruit development, with water around to swell the berries.

    • Large numbers of potentially fatal Portuguese manofwar prompted the closure of a Cornish beach.
    • RNLI lifeguards closed Perranporth beach when they found "an unusually large number" of the manofwar.
    • The jellyfishlike creatures with long purple tentacles have been seen in Cornwall and Wales this month says the Marine Conservation Society (MCS).
    • More on the manofwar sightings and other stories from Cornwall Manofwar were spotted at Newgale, Pembrokeshire, on 8 September and the next day on beaches around holiday destination Newquay.
    • The NHS recommends using tweezers or a clean stick, and gloves if possible, to remove manofwar tentacles.

    • The international Cassini probe at Saturn will execute the course correction on Monday that will put it on a path to destruction.
    • Once the orbit has been tweaked, nothing can stop the death plunge.
    • "We're going to go so deep into the atmosphere the spacecraft doesn't have a chance of coming out."
    • BBC News will have live coverage of the ending of the mission on both TV and radio.
    • A special Horizon documentary will review the mission and the final hours on Monday 20 September at 21:00 BST on BBC Two.

    • A photographer has won a twoyear legal fight against an animal rights group over a "monkey selfie" photograph.
    • Peta's appeal on the "monkey's behalf" was dismissed but Mr Slater has agreed to donate 25% of any future revenue.
    • Mr Slater, of Chepstow, said he put in a lot of effort which was more than enough for him to claim copyright.
    • But appeal judges at a court in San Francisco ruled in Mr Slater's favour after a twoyear legal fight.
    • In the jointstatement between Peta and Mr Slater, they say this case "raises important, cuttingedge issues about expanding legal rights for nonhuman animals".
