Record-breaking fly-by, Japanese whaling and Ebola troubles

POLICY

Japanese whaling Japan has been condemned for its decision to withdraw from the International Whaling Commission (IWC) and resume commercial whaling. The government announced on 26 December that it will begin commercially hunting the mammals in its waters this year, but will end its whaling programme in the Southern Ocean. The IWC, based in Cambridge, UK, introduced a moratorium on whaling in 1986, but Japan has continued to hunt the mammals, citing scientific purposes. Last year, the IWC rejected the government鈥檚 bid to restart commercial whaling. Japan says it will now participate in the IWC only as an observer.

EVENTS

Indonesian tsunami Part of Indonesia鈥檚 Anak Krakatau volcano collapsed on 22 December during an eruption, triggering a tsunami that hit the coasts of Java and Sumatra and killed at least 430 people. Satellite and aerial images later confirmed that much of the western flank of the volcano had disappeared into the sea. The blast reduced Anak Krakatau to one-third of its previous height. The volcano had been erupting since June. It originally formed from the remains of the volcano Krakatau, whose 1883 eruption generated a tsunami that killed at least 36,000 people.

SPACE

Ultima Thule fly-by On 1 January, NASA鈥檚 New Horizons spacecraft flew past the space rock 2014 MU69, nearly 6.5 billion kilometres from Earth 鈥?the most distant Solar System object ever visited. Early images, taken before the spacecraft whizzed just 3,500鈥塳ilometres above MU69鈥檚 surface, showed an elongated blob that resembles a bowling pin. The object 鈥?which researchers have nicknamed Ultima Thule 鈥?is spinning almost directly face on to Earth, like a propeller blade.

POLITICS

US shutdown Several major US science agencies shut down indefinitely on 22 December after politicians failed to reach a deal to continue funding government operations. NASA, the National Science Foundation, the Environmental Protection Agency and the Food and Drug Administration are among the agencies affected by the shutdown 鈥?the third in 2018. By law, they must curtail all activities except those considered essential for protecting life and property. It is not clear when the funding impasse will end; President Donald Trump says that any budget deal must include US$5 billion to construct a wall along the US border with Mexico, but Democrats in Congress say they will not vote for such a plan.

Ebola troubles Political protests are thwarting Ebola control efforts in Beni and Butembo, northeastern cities in the Democratic Republic of the Congo. On 28 December, the World Health Organization reported that it is struggling to carry out measures such as identifying people potentially infected with the virus. In Beni, protesters robbed and set fire to an Ebola centre. The unrest follows President Joseph Kabila鈥檚 decision to suspend voting in presidential elections in Beni, Butembo and Yumbi, which are opposition strongholds. Observers suspect that his motivation is to suppress votes.

TREND WATCH

Emerging and developing economies showed the largest increases in research output in 2018. Pakistan and Egypt topped the list in percentage terms, with rises of 21% and 15.9%, respectively. China鈥檚 publications rose by about 15%, with India, Brazil, Mexico and Iran all seeing their output grow by more than 8% compared with 2017.

This diversification of players in science is a phenomenal success, says Caroline Wagner, a science-policy analyst at the Ohio State University in Columbus. 鈥淚n 1980, only 5 countries did 90% of all science 鈥?the United States, the United Kingdom, France, Germany and Japan,鈥?she says. 鈥淎nd now there are 20 countries within the top producing group.鈥?

Globally, the output rose by around 5% in 2018, to an estimated 1,620,730 papers listed in the Web of Science science-citation database. The data were compiled for Nature by Clarivate Analytics, owner of Web of Science, which says the overall rise is comparable to increases over the past few years, and is likely to continue in 2019. It鈥檚 not yet clear what is driving the rises in emerging nations; they could be partly due to changes in how the database is curated, to add more local and national journals.
