Despite the wettest week in England in two years, Wales and most of England remain in drought, with parts of southern England in severe drought. Recent rain from storms Austen and Boelo brought up to 87mm in some areas, but the National Drought Group says sustained and above-average rainfall over a seven-month period is needed for conditions to improve to normal.
Fragments of personal objects, including a small glass perfume bottle and a child's necklace, have been found in a wooden wardrobe sealed for almost 2,000 years in the ruins of Pompeii, offering an intimate glimpse of daily life before the city was devastated by the eruption of Mount Vesuvius in AD79.
NASA has asked commercial space companies for information on servicing the Hubble Space Telescope, with options including boosting its orbit, enhancing its performance and resilience, or conducting a controlled reentry.
Astronomers have reported an unprecedented gamma-ray burst event, GRB 160425A, in which two distinct bursts, one short and one long, erupted just four minutes apart. Detected in 2016 by the Neil Gehrels Swift Observatory, the event is described in a paper published in Nature Astronomy and may require a rethink of how gamma-ray bursts are classified and how they originate.
A new three-dimensional map suggests the interstellar medium is more dynamic and unstable than long assumed, with researchers finding 41% of the ISM in the galactic neighbourhood in an intermediate state that contradicts leading theoretical models taught in textbooks.
A new global study has found that venomous snakebites could be killing between 274,000 and 513,000 people every year, a toll vastly higher than official statistics have reported. The research, which reviewed data from 79 countries and used a geostatistical model to account for widespread under-reporting, reveals a public health crisis that mostly affects poor rural communities.
New observations from NASA’s Hubble Space Telescope have thrown a leading theory of the early universe into question. An international research team, including astronomers from the University of Michigan, found that powerful winds generated by exploding stars can prevent ultraviolet radiation from escaping galaxies, the opposite of what a widely accepted theory had predicted. The discovery, published in Nature Astronomy, could change how scientists understand reionisation, the period about 13 billion years ago when the universe emerged from its cosmic fog.
A computer scientist has improved an algorithm for calculating shortest paths in large networks, extending a mathematical guarantee that had remained unchanged since 1996. Dr. Manoj Gupta of the Indian Institute of Technology Gandhinagar introduced a multi-scale sampling strategy that enables more reliable distance estimates for points close together, without slowing down the algorithm.
A physicist at the University of Birmingham has built a miniature universe from about 24,000 atoms cooled to billionths of a degree above absolute zero and shown that a form of time can emerge from changes inside the system without an external clock. The findings, published in Physical Review Research, offer experimental support for the idea that time may not be a fundamental feature of reality but something that arises from the relationships and changes within the universe itself.
A new clinical trial has found that a combined diet and exercise program can help younger adults with type 2 diabetes achieve remission. Researchers reported that 54% of participants who followed an intensive regimen achieved remission within six months, compared to only 4% of those receiving standard care.
Beavers are set to return to the waters around Loch Ness for the first time in 500 years, after conservation charities were given permission to release up to 15 beaver families into the area over the next three years. The first reintroduction could potentially take place in November.

From the start of November, the Police Service of Northern Ireland will stop carrying out concern-for-welfare checks unless there is a risk to life or harm, or a crime is involved, under a new policy called Right Care Right Person. The change, which has been in place among some forces in England and Wales since 2023, is intended to ensure individuals receive care from the most appropriate professional, but health and social care representatives have raised concerns about whether there are sufficient resources to implement it safely.
Australia faces an array of potential invasive species that could cause serious harm, according to a new column by Carol Booth, policy director at the Invasive Species Council. Writing for Halloween, Booth suggested that complacency may be the real monster, as she detailed threats including an alga known as rock snot, a tiny beetle carrying tree-killing fungus, and a fish that can wriggle across land.
