Mars Rover Detects Never-Before-Seen Organic Compounds In New Experiment

NASA's Curiosity rover has identified a diverse set of organic molecules on Mars, including a nitrogen-bearing compound similar in structure to DNA precursors. The finding strengthens the case that ancient organic material can survive in the Martian subsurface, though it does not prove past life because the compounds could also come from geology or meteorites. Phys.org reports: The study was led by Amy Williams, Ph.D., a professor of geological sciences at the University of Florida and a scientist on the Curiosity and Perseverance Mars rover missions. Curiosity landed on Mars in 2012 to find evidence that ancient Mars had conditions that could support microbial life billions of years ago; the Perseverance rover, which landed in 2021, was sent to look for signs of any ancient life that might have formed. Among the 20-plus chemicals identified by the experiment, Curiosity spotted a nitrogen-bearing molecule with a structure similar to DNA precursors -- a chemical never before spotted on Mars. The rover also identified benzothiophene, a large, double-ringed, sulfurous chemical often delivered to planets by meteorites. "The same stuff that rained down on Mars from meteorites is what rained down on Earth, and it probably provided the building blocks for life as we know it on our planet," Williams said. The findings have been published in the journal Nature Communications.

FBI Looks Into Dead or Missing Scientists Tied To Sensitive US Research

Federal authorities are now reviewing a string of deaths and disappearances involving scientists tied to sensitive U.S. aerospace and nuclear work, though officials have not established any confirmed link between the cases. The FBI says it "is spearheading the effort to look for connections into the missing and deceased scientists," adding that it "is working with the Department of Energy, Department of War, and with our state ... and local law enforcement partners to find answers." The Republican-led House Oversight Committee also announced an investigation into the reports. CNN reports: A nuclear physicist and MIT professor fatally shot outside his Massachusetts residence. A retired Air Force general missing from his New Mexico home. An aerospace engineer who disappeared during a hike in Los Angeles. These are among at least 10 individuals connected to sensitive US nuclear and aerospace research who have died or disappeared in recent years, prompting concerns whether they are connected and fueling speculation online about the possibility of nefarious activity. [...] The Defense Department said only that it would respond to the committee directly, and the Department of Energy referred questions to the White House. In a post on X, NASA said it is "coordinating and cooperating with the relevant agencies" in relation to the scientists. "At this time, nothing related to NASA indicates a national security threat," NASA spokesperson Bethany Stevens said. The cases vary widely in circumstance. Some involve unsolved homicides, while others are missing persons cases with no signs of foul play. In at least two instances, families have pointed to preexisting medical conditions or personal struggles as explanations. Authorities have not established any links between the cases. The White House said last week it is also working with federal agencies to probe any potential links between the deaths and disappearances, with President Donald Trump referring to the matter as "pretty serious stuff." "The United States has thousands of nuclear scientists and nuclear experts," said Rep. James Walkinshaw, a Democrat who also serves on the Oversight Committee. "It's not the kind of nuclear program that potentially a foreign adversary could significantly impact by targeting 10 individuals."

SpaceX Strikes Deal With Coding Startup Cursor For $60 Billion

An anonymous reader quotes a report from the New York Times: SpaceX, Elon Musk's rocket and satellite company, said on Tuesday that it had struck a deal with the artificial intelligence start-up Cursor that could result in its acquiring the young company for $60 billion. SpaceX is making the deal just as it prepares to go public in what is likely to be one of the largest initial public offerings ever. In a social media post, SpaceX said the combination with Cursor, which makes code-writing software, would "allow us to build the world's most useful" A.I. models. SpaceX added that the agreement gave it the option "to acquire Cursor later this year for $60 billion or pay $10 billion for our work together." It is unclear if the companies plan to consummate the deal before or after SpaceX's I.P.O., which could happen as early as June. [...] Cursor, which has raised more than $3 billion in funding, was founded in 2022 and made waves as a fast-growing A.I. start-up. It was under pressure in recent months after OpenAI and Anthropic announced competing code-writing products that were embraced by tech companies. Cursor had been in talks to raise funding in recent weeks.

Some tech company to replace its CEO

I need to post about this because if I don't, people will get mad. Cook will continue on as Apple CEO through the summer, with Ternus set to join Apple's Board of Directors and take over as CEO on September 1, 2026. Cook is going to transition to chairman of the board at Apple, and he will "assist with certain aspects of the company, including engaging with policymakers around the world." ↫ Juli Clover at MacRumors This concludes OSNews' coverage of Keeping Up With the Yacht Class, but rest assured, every other tech site will be milking this for weeks to come. You will still be worrying about how to pay for your next tank of gas.

Google to punish back button hijacking

Have you ever tried clicking the back button in your browser, only to realise the website you're on somehow doesn't allow that? Out of all the millions of annoyances on the web, Google has decided to finally address this one: they're going to punish the search rankings of websites that use this back button hijacking. Pages that are engaging in back button hijacking may be subject to manual spam actions or automated demotions, which can impact the site's performance in Google Search results. To give site owners time to make any needed changes, we're publishing this policy two months in advance of enforcement on June 15, 2026. ↫ Google Search Central It's always uncomfortable when Google unilaterally takes actions such as these, since rarely do Google's interests align with our own as users. This is in such rare case, though, and I can't wait to see this insipid practice relegated to the dustbin of history.

LXQt 2.4.0 released

LXQt, the desktop environment which is effectively to KDE what Xfce is to GNOME, has released version 2.4.0. Quite a few changes in this release are further refinements and fixes related to LXQt's adoption of Wayland, but there are also a ton of small fixes, improvements, and small new features that have nothing to do with Wayland at all. There are also a few layout cleanups to make some dialogs and panels look a bit tidier and nicer. Note that LXQt supports both X11 and Wayland equally, and the choice of which to use is up to you. If you're using LXQt, you've already seen a few of these changes in point releases of its components, so not everything listed in the release notes might be news to you.
