Deleting AI chats may not erase every trace - Futurity

Newswise — Deleting a conversation with an artificial intelligence (AI) assistant may not erase everything the assistant remembers. Georgia Tech researchers have developed a tool that can recover deleted conversations from AI assistants running on Android phones. The tool, called ORISA, can also rebuild the recovered information into a working AI session. The findings show that deleting an AI conversation on a phone does not necessarily mean it removes every trace. The research could give digital investigators a new way to recover information from phones. It also raises privacy concerns for people who use AI assistants that run locally on their devices. Local AI assistants run directly on a phone rather than sending conversations to a cloud service. While the local assistant is running, information from conversations can remain in the phone’s working memory even after it is deleted. ORISA searches this memory for pieces of deleted conversations. In one experiment, researchers created a fictional AI assistant called “Project Note Keeper” using the ChatterUI Android app. They gave it 100 fictional facts about a project, then deleted the conversation.

A facial mass detected before birth prompted the early delivery of identical twin sisters. A fetal MRI at 33 weeks showed the mass on one baby's face. When the sisters were born a week later, tumors were found in both. Two children had the same cancer, raising a question that their shared beginnings alone could not answer. Had the disease started separately in each sister, or had cancer cells crossed from one to the other before birth? Researchers turned to a record hidden within their cells. DNA changes, accumulated as their bodies developed, allowed the team to reconstruct events that had happened months before anyone saw a tumor. The study in Nature Communications shows that the cancer began in one sister and passed to the other in the womb, most likely through a single transfer late in the second trimester. The same investigation uncovered clues to how the sisters themselves had formed. The two girls, Amelia and Amaya, died soon after birth. Their family consented to post-mortem examinations for research. The authors dedicate the study to the sisters, whose mother wanted them acknowledged by name.

The Blood of Dawnwalker is already one of the best role-playing games of the year, but developer Rebel Wolves is preparing a big update that should make it even better. Like all good things in life, it starts with getting to pet a dog. Update 1.1, which is scheduled to arrive next week, brings a number of new features to the game, including the ability to pet both dogs and cats via the game's directional system, which is currently only used for combat. It will also feature a new Story difficulty setting that provides "additional combat assist," new subtitle settings across all lines of dialogue, and most crucially, an item called Draught of Mind Rebirth. The Draught of Mind Rebirth will allow you to forget all the skills and abilities you've acquired across the Swordmastery, Witchcraft, and Vampirism trees. Not only will this give you the chance to reallocate your points in a way that best fits your playstyle--it will also give you back the time associated with those skills. That means you'll have the chance to complete extra missions if you happen to find yourself impeded with Dawnwalker's 30-day limit. However, we don't find the system to be restrictive as it currently stands. Th

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
