Bizarre extinct frog brought back to life


Recommended Posts

Imagine a frog that can swallow its eggs, brood its young in its stomach and give birth through its mouth.

The gastric brooding frog existed 30 years ago, but the extraordinary amphibian is now extinct.

In a world first, a team of Australian scientists has taken the first major step in bringing it back to life.

They have successfully reactivated its DNA and produced an embryo.

Professor Mike Archer from the University of New South Wales is part of the team, which also includes researchers from the University of Newcastle.

He says the amphibian was no ordinary frog.

"In the stomach these eggs went on to develop into tadpoles and the tadpoles then went on to develop into little frogs," he told ABC radio's AM program.

"And like any pregnant mum, when you have little babies rattling away in your stomach saying, 'let me out', she would then open her mouth and out would pop little frogs.

"The first people that saw that were aghast. By the time anybody got excited about it, suddenly it was extinct.

"So that's certainly one of the driving reasons why this would be a focal animal for seeing if we can de-extinct this amazing frog."

FYI, high on the list for a resurrection are the mammoths, dodos and saber toothed cats. Since N. Carolina State scientists and the Palo Alto Research Center (PARC) have found T-Rex cells, and possibly DNA, in fossils you can't write them off either.

Last estimate I saw for a 30 - 40 ton apatasaur was 1-2 tons a day. The very large vegetarians retained heat better than the smaller predators due to a small surface area to volume ratio (aka: gigantothermy) and moved much slower, so they had lower metabolisms.

Even elephants have a problem with retained heat, more so be ause they're more warm blooded, so they use their ears as radiators and frequently spray themselves with water.

"Doctors borrowed some DNA segments from Yersinia pestis to complete the sequences. When asked if the use of this DNA could cause issues with mutation the doctors answered... 'No there could absolutely be no issue in that reg * AAAACK * NOOOOOOOOO!!!!"

    • Doogee and Ulefone regularly release phones with 10k-25k mAh batteries, but those are bricks. I don't understand how they could make it only weigh 220 grams with a battery that size.
    • Windows 10 quietly gets one more year of support and updates by Taras Buria Windows 10 reached its end of life at the end of 2025. Microsoft kicked off the Extended Security Updates program, aimed at giving regular consumers one more year of security-only updates. By doing so, Microsoft gave users more time and money to update their computers to a newer operating system or compatible hardware. Now, with the end of the Extended Security Updates program quickly approaching, Microsoft is making an important adjustment. Users discovered that the official support article for the program now lists a new end-of-support date: The Extended Security Updates program is not a new concept. It has been an official way for business consumers to continue receiving critical updates for unsupported Microsoft products for many years. However, all this time, it was a business-only, paid feature. With Windows 10, Microsoft brought ESU to regular consumers, allowing them to get security updates for Windows 10 past October 2025 essentially for free. When Windows 10 was approaching the end of support, many guessed that Microsoft might adjust its support timelines, and this is exactly what seems to be happening. Of course, Microsoft would love everyone to switch to new computers, such as its latest Surface devices, but in the days of ever-growing hardware prices, not everyone is lucky enough to have money for a new PC. Leaving hundreds of millions of customers with a Windows version that no longer receives security updates is a major risk that Microsoft is not willing to take. If you have a Windows 10 PC to enroll in the Extended Security Updates program, check out this guide to learn how to do so.
    • Sony announces Bungie layoffs that will affect "significant number of employees" by Pulasthi Ariyasinghe Sony today announced that major layoffs are happening at its first-party studio Bungie, the developer that has spawned series like Halo, Destiny, and Marathon over the past decades. The news arrives just weeks after Bungie delivered the final update to Destiny 2, and it's that team being hit with the layoffs the most. CEO of Sony Interactive Entertainment Hermen Hulst revealed the staff reduction today, calling it "painful news." "Over the past several months, together with Bungie leadership, we reviewed the studio’s long-term direction, development priorities, resource needs, and role within our broader portfolio strategy," said Hulst, explaining the decision. "We explored multiple alternatives before concluding that a reduction was necessary to align the studio’s resources with its current priorities and long-term goals." The layoffs will be hitting "a significant number of employees" across most of the Destiny franchise development team. It doesn't look like Sony is planning to continue the series following Destiny 2's sunsetting update. The studio is said to be in early stages of looking at other projects to pivot to, but it's said that keeping the size of the team at current levels is no longer feasible. "We know this decision has a profound impact on the people affected, their families, friends, and teammates," said Bungie leadership in a separate message on social media. "While these changes are necessary to best position the studio now and for the future, that does not lessen the difficulty of this moment or the impact it has on those affected." At the same time, "some" of the Marathon development team are also affected by the layoffs. The recently released multiplayer-only extraction shooter title hasn't seen a big boom of players either, but the company is reportedly hoping that the live service experience will pick up players with future updates.
    • Microsoft adds reusable skills and finance data connectors to Copilot in Excel by Karthik Mudaliar Microsoft is giving Copilot in Excel a collection of new features aimed squarely at finance teams. The update introduces reusable instructions for common tasks, connections to services such as FactSet and Morningstar, and a better way to review what Copilot intends to do before it starts changing a workbook. The most interesting addition is 'Skills' finally coming to Copilot in Excel. Skills let companies teach Copilot how to handle a recurring process, so employees do not need to write the same detailed prompt every month. Users can create skills that can specify the steps Copilot should follow, along with the required layout, formulas, and formatting. Microsoft says users can create their own skills by saving a SKILL.md file in OneDrive. The file is written using Markdown and tells Copilot when and how to perform the task. Once it is available, a user can select the skill in the Copilot pane or mention it in a prompt using the @ symbol. There is also a library of prebuilt finance skills for customers who do not want to create their own. Microsoft plans to let developers distribute additional skills through the Microsoft Marketplace and the Microsoft 365 Admin Center, with LSEG, Ramp, Rogo, samaya.ai, Velixo, and Vena among the first partners involved. The company says that it is also expanding the external data that Copilot can access from inside Excel. New connectors are being added for CB Insights, Daloopa, FactSet, Morningstar, PitchBook, and S&P Global data through technology developed by Kensho. There is a catch, however. Accessing these services may require a separate subscription from the relevant data provider, so a Microsoft 365 Copilot licence will not necessarily unlock all of them. FactSet is also only available in preview for now, with general availability planned for July. Microsoft is also trying to make Copilot’s workbook edits easier to inspect. Users can switch to a planning mode that shows which sheets, cell ranges, formulas, and assumptions Copilot intends to work with before it begins making changes. Once the work is complete, the Show Changes pane can distinguish edits made by Copilot from those made by human collaborators. The update continues Microsoft’s push to turn Excel Copilot from a chatbot into an agent that can carry out longer tasks. The company previously added an Agent Mode capable of planning and completing multi-step Excel work. Microsoft also recently acquired financial AI startup Fintool, another indication that finance is becoming a key target for its Excel AI strategy. Prebuilt skills, personalization, workbook rules, external connectors, planning mode, and Copilot attribution in Show Changes are generally available to Microsoft 365 Copilot customers using Excel on the web, Windows, and macOS. Custom skills are initially available to Microsoft 365 Insiders on Windows and Mac starting today. Microsoft plans to make them generally available across Windows, Mac, and the web over the next month. Partner-built skills are expected during the third quarter of the year. Availability may still differ depending on region and licensing.
    • Exactly. They serve different (although related) purposes.
