Daily briefing: The proteins that protect us from deadly mutations

NATURE BRIEFING

18 June 2026

Proteins that ‘buffer’ the effects of mutations could help to treat diseases such as cancers. Plus, goats can follow human voices and the battle over a key ocean observatory project in the United States.

Asia and the Pacific suffer under rising heat

Sea levels and ocean temperatures reached alarming highs in Asia last year , while Japan, China and Korea all recorded their hottest summer on record. Deadly floods hit Pakistan, extreme rain fell in Sri Lanka and 14 tropical cyclones impacted the Macao region. “The report clearly shows that the Asian region is one of the most vulnerable to climate change,” says oceanographer Matthew England. Early warning and coordinated action will be essential to save lives, says the report.

Should nicotine be regulated like drugs?

A call by the Pacific island nation of Palau for nicotine to be regulated like narcotics by the United Nations will trigger an assessment and a vote by member states. If nicotine were to be added to the UN Convention on Psychotropic Substances, it would effectively make it illegal to sell nicotine products that aren’t considered medicinal , says nicotine-treatment specialist Renee Bittoun. But tobacco-company lobbying makes it unlikely that nicotine will be added to the list, says Bittoun.

Goats can follow our dulcet tones

Domestic goats ( Capra hircus ) can follow the voice of a person to find a reward. A group of goats were each presented with two buckets, one empty and one containing food. When a hidden researcher spoke enthusiastically in the direction of the full bucket, the goats moved toward it 60% of the time — more often than would be expected by chance. Voice-following abilities have previously been found in dogs, but not chimpanzees, which could suggest that the skills arose through domestication.

US ocean observatory on the chopping block

Last month, the National Science Foundation (NSF) abruptly decided to dismantle much of the Ocean Observatories Initiative (OOI) — a network of underwater and floating infrastructure, and a fixed subsea observatory in the Pacific Northwest. Marine scientists have long debated the correct balance between spending on costly infrastructure like these, and funding research grants. But the sudden break-up of OOI has triggered widespread condemnation. The NSF has not shared its reasoning for the decision, so researchers are left wondering to what extent the move reflects scientific priorities, policy changes or the predilections of the Trump administration.

The first removals of instrumented moorings were scheduled to begin today. There has been a bipartisan effort by some lawmakers to stop the process , and Democrats from the US Senate have called the move “expensive, destructive, and — crucially — illegal”.

Where academic freedom is up (and down)

Bangladesh, Uzbekistan and Montenegro are among the nine countries that have seen significant improvements in academic freedom in the past ten years, says a new report that looks at individual and institutional metrics. Meanwhile, 50 countries — including big hitters such as the United Kingdom — experienced declines . The report specifically calls out the “fast and steep deterioration” of academic freedom in the United States because of “state and federal attacks [that] have generated severe pressure on American universities”.

The proteins that protect us from mutations

Our genomes are full of mutations that have the potential to cause harm. But often they don’t, thanks to a family of proteins that ‘buffer’ the mutation’s ill effects . These proteins, called HSPs, have been on scientists’ radar for decades, but advances in techniques such as cell screening and genetic editing are giving new insight into the proteins’ roles. Researchers are now trying to unpick how buffer proteins have influenced human evolution, and are investigating how to exploit them in treatments for diseases such as breast cancer.

Galápagos sharks (Carcharhinus galapagensis) have been caught on camera scraping up against manta rays ( Mobula birostris ) to scratch themselves . The backs and bellies of mantas are covered with rough dermal denticles that might help the sharks scrape parasites off their snouts and gills. The mantas don’t seem to mind when young sharks do it, but get a bit skittish when bigger sharks get too close for comfort.
