The unknown pervades the universe. That which people can see, with the aid of various sorts of telescope, accounts for just 4% of the total mass. The rest, however, must exist. Without it, galaxies would not survive and the universe would not be gently expanding, as witnessed by astronomers. What exactly constitutes this dark matter and dark energy remains mysterious, but physicists have recently uncovered some more clues, about the former, at least.

One possible explanation for dark matter is a group of subatomic particles called neutrinos. Neutrinos are thought to be the most abundant particles in the universe. According to the Standard Model, the most successful description of particle physics to date, neutrinos come in three varieties, called "flavors". Again, according to the Standard Model, they are point-like, electrically neutral and massless. But in recent years, this view has been challenged, as physicists realized that neutrinos might have mass.

The first strong evidence came in 1998, when researchers at an experiment, based in Japan, showed that muon neutrinos produced by cosmic rays hitting the upper atmosphere had gone missing by the time they should have reached an underground detector. Its operators suspect that the missing muon neutrinos had changed flavor, becoming electron neutrinos or-more likely-tau neutrinos. Theo- ry suggests that this process, called oscillation, can happen only if neutrinos have mass.

Over the coming months and years, researchers hope to produce the most accurate measurements yet. The researchers created a beam of muon neutrinos first. On the other side of the target sat a particle detector that monitored the number of muon neutrinos leaving. The neutrinos then travelled 750km (450 miles) through the Earth to a detector in a former iron mine in Soudan, Minnesota. Researchers then were able to confirm that a significant number of muon neutrinos had disappeared-that is, they had changed flavor. While their mass is so small that neutrinos cannot be the sole constituent of dark matter, they have an advantage in that they are at least known to exist.

The same cannot be said for sure of another possible form. of dark matter being studied by a group of physicists in Italy. If the result continues to withstand scrutiny, it would appear to be evidence for an exotic new sort of fundamental particle, known as an axion, which could also be a type of dark matter.

I’m a big fan of trying to save the environment, and this month is the WWF (World Wide Fund for Nature) annual Earth Hour. Earth Hour is an event where you 73_________ and power between 8-9 pm, things like your TV and computer. However, you don’t just 74_________ for an hour. Instead, people gather in groups and have fun without using power. Things like dancing, fireworks and musical performances are popular and it’s very fun to take part. Earth Hour isn’t just about saving energy; people involved in Earth Hour have also planted a forest in Uganda, built 75_________

start filming in England, according to Warner Bros. In this movie, Potter returns for his fifth year of study at Hogwarts, only to find the school turning a blind eye to his recent fight with the cruel Lord Voldemort. He decides to take matters into his own hands and begins to form. an army of students, whom he trains to defend themselves against the Dark Arts.

Daniel Radcliffe, Rupert Grint and Emma Watson again play their roles as Harry, Ron and Herminone, while British director David Yates is to guide the adventure. Rowling released (推出) the sixth book in the series (系列), Harry Potter and the Half-Blood Prince, last July, while the seventh and final book is expected by the end of the year.

Harry Potter and the Order of the Phoenix is expected for a 2007 release, but there is no word yet whether it will be a summer or holiday movie.
