Tropical Storm Isaias forms in the Gulf

Isaias became a tropical storm Wednesday with sustained winds of 40 mph. The National Hurricane Center forecasts strengthening into a hurricane by Thursday and an approach to the northern U.S. Gulf Coast Friday. Its early-morning advisory projected 3–6 inches of rain from far southeastern Louisiana to the Florida Panhandle, with localized totals reaching 10 inches. Rain could extend inland into the Southeast, creating possible flooding. The storm’s eventual strength and track remain uncertain. No coastal watches or warnings were in effect when the advisory was issued, although hurricane watches were expected later Wednesday. Tropical Storm Isaias Advisory Number 3

India raises its benchmark interest rate to 5.50%

The Reserve Bank of India raised its benchmark lending rate by a quarter percentage point Wednesday to 5.50%, its first increase since February 2023. All six monetary-policy committee members supported the move. Inflation reached 4.8% in August, above the bank’s 4% target, as energy costs and a weaker rupee complicated price control. Higher rates can restrain borrowing and spending, while increasing financing costs for households and businesses. The bank also adopted a tightening stance, ruling out near-term cuts and saying its next decision would be a further increase or a pause, depending on conditions.

Kenya confirms its first Ebola case and death

Kenya confirmed Tuesday that a man who returned from Congo had become the country’s first confirmed Ebola case and died Monday. Authorities said he had fallen ill abroad, arrived in Nairobi Saturday and was immediately isolated at hospital. Officials identified 28 contacts, including relatives and health workers, and were tracing another 23 passengers and four crew members from his flight. The response focuses on monitoring exposed people and detecting any additional cases. An imported case alone does not establish sustained transmission within Kenya, which had never previously recorded an Ebola outbreak.

Chemistry Nobel honors control of mirror-image molecules

Henri B. Kagan and Kenso Soai won Wednesday’s Nobel Prize in Chemistry for discoveries that help reactions favor one molecular form over its mirror image. Kagan showed how a small imbalance could be amplified; Soai developed reactions whose products help produce more of themselves. Such control matters because mirror-image molecules can interact differently with living organisms, making selective manufacturing important for medicines. The award recognizes discoveries beginning in the 1980s and 1990s. Their work demonstrates how chemical asymmetry can emerge, while leaving open exactly how life acquired its molecular preferences.

Australian court rules coal-mine expansion approval invalid

Australia’s High Court ruled Wednesday that approval of the Mount Pleasant coal-mine expansion was invalid. A 3–2 majority found that planning authorities had failed to consider conditions minimizing emissions from coal burned after export. The proposed expansion would double annual output to 21 million tonnes and extend operations to 2048. The New South Wales government says a separate approval allows the existing mine to operate until 2032 and that the expansion can be reconsidered. The ruling therefore changes the requirements for assessing the proposal, with any revised approval dependent on meeting those legal obligations.

Pocket mice gain a third reintroduced population

San Diego Zoo Wildlife Alliance announced Tuesday that its partners had established a third reintroduced population of endangered Pacific pocket mice, at Camp Pendleton’s North San Mateo area. The conservation program has released more than 500 mice into new and existing populations since beginning its work in 2006. These small Southern California mammals also have an ecological role: their burrows help move water and nutrients through soil and shelter other species, the organization says. Additional populations can spread conservation risk, while lasting recovery depends on the mice surviving and reproducing in the wild.
