Identifying a new species is not always straightforward. Scientists usually rely on physical traits that separate one species from another, but in nature those differences do not always fall into neat categories. Sometimes two different species look almost identical. These are called cryptic species. In other cases, a single species can vary so much in appearance that it seems like several different species instead. The challenge becomes even greater when both patterns show up at the same time.
Herpetologist Dr. Chan Kin Onn (previously at the Lee Kong Chian Natural History Museum, Singapore, now with the University of Kansas Biodiversity Institute and Natural History Museum, USA) led research on a pit viper from Myanmar that seemed to be both similar to and distinct from its closest relatives. The work was published in the open access journal ZooKeys, building on an earlier genomic study in Systematic Biology that had already indicated the snakes represented a separate evolutionary lineage.
“Asian pit vipers of the genus Trimeresurus are notoriously difficult to tell apart, because they run the gamut of morphological variation. Some groups contain multiple species that look alike, while others may look very different but are actually the same species,” they say.

A new experimental hair-loss treatment has drawn global attention after researchers reported encouraging early results from a plant-based scalp serum. Scientists in Taipei, led by Dr Tsong Min Chang of Schweitzer Biotech Company, found that volunteers using the formula for eight weeks showed measurable improvements in hair density and thickness compared with a placebo group. The serum combines plant-derived compounds from Centella asiatica with ingredients already used in cosmetic and scalp-care products. While the findings are still preliminary and require larger independent trials, the study has raised interest because many current hair-loss treatments can take months to show results and do not work equally well for every user.

OpenAI launched a new image generation AI model on Tuesday, dubbed ChatGPT Images 2.0. This model can generate more than one image from a single prompt, like an entire study booklet, as well as output text, including in non-English languages like Chinese and Hindi. This release is available globally for ChatGPT and Codex users, with a more powerful version available for paying subscribers.
When any major AI company releases a new image model, it can revive interest and boost usage, especially if social media users adopt a meme-able trend, transforming images of themselves. Last year, Google’s launch of the Nano Banana model was a major moment for the company, especially when users started posting hyperrealistic figurines of themselves online. Earlier this year, ChatGPT Images made waves on social media as users shared AI-generated caricatures.

Looking at enterprise AI adoption, VentureBeat has anecdotally observed a fairly wide divergence when it comes to specific roles: For those who build—engineers and developers—the arrival of AI has been transformative, moving through the workflow with the speed of tools like Claude Code and Cursor to automate the heavy lifting of syntax and architecture.
Yet, for those who sell, the “revenue stack” has remained a fragmented collection of data silos, manual CRM entries, and anecdotal reporting.
Von, a new AI platform emerging from the team behind process automation startup Rattle, aims to bridge this gap. By positioning itself not as another “point solution” but as a foundational “intelligence layer,” Von seeks to do for Go-To-Market (GTM) teams what the modern IDE has done for the developer: provide a single, reasoning interface that understands the entire business context.
“AI has revolutionized the workflow for people who build things, but there is nothing that has revolutionized the workflow for people who sell those things,” Von CEO Sahil Aggarwal said in a recent video call interview with VentureBeat. “That is what we are trying to build with Von”.

Two weeks after unfounded rumors said President Donald Trump suffered a health issue, social media users shared a video they said showed proof he was just taken to a hospital.
In the video, two men appear to assist Trump as he walks unsteadily out of a building. A sign on the building reads “Walter Reed National Military Medical Center.”
“BREAKING: There are some reports Trump has been taken to Walter Reed Hospital,” the captions of multiple Facebook posts sharing the video read. The earliest we found was posted April 19 and the latest was posted April 21.
The footage isn’t real. It contains signs that it was made with artificial intelligence.
We contacted the Walter Reed hospital’s communications office, which said that the logo shown in the video is not the hospital’s official logo, and the signage is inconsistent with that at the hospital.

Neanderthals are also continuing their own journey through history, and the latest scientific study conducted at Stajnia Cave in Poland is bringing an exciting new dimension to it. For the first time, scientists have been able to reconstruct what appears to be the oldest Neanderthal population in Central-Eastern Europe, thereby giving us more information about how these prehistoric humans were able to adapt to and survive in the wild. Through the use of DNA from cave deposits dating back over 80,000 years, scientists have managed to piece together the information regarding this group of Neanderthals.
This discovery is based on an in-depth examination of DNA taken from the Neanderthal tooth discovered in Stajnia Cave. Using highly sophisticated paleogenomic methodology, the scientists have successfully analysed the mitochondrial DNA and came to the conclusion that the Neanderthal was from a branch genetically connected with their contemporaries who lived in the Caucasus area.As reported in the article “First multi-individual Neanderthal mitogenomes from north of the Carpathians,” published by Scientific Reports, this discovery implies significant migration or at least contacts of the populations living over a large territory of Eurasia. As the researchers write:“The genetic affinities of the Stajnia individual imply connections between the populations of Central European and Caucasus Neanderthals.”In other words, there were no isolated communities of Neanderthals in Europe.

So far, America has remained ahead in the new space race. But its biggest rival is making continual steps to catch up. China announced another step in that direction with the unveiling of its first ever reusable five-meter-wide composite propulsion module, announced in a press release on April 11th.
The module was designed by the China Aerospace and Technology Corporation (CASC), the primary state contractor for the Chinese space program. Specifically, it was developed at the China Academy of Launch Vehicle Technology (CALT), which is also known as the First Academy of the CASC. It marks the largest integrated composite structure ever manufactured domestically for China’s aerospace sector. The first prototype was completed in just seven months, from initial design to delivery, underscoring the rapid development timeline.
Composites are becoming a critical feature of modern launch systems. Traditional metal components simply weigh too much. The more structural weight a launch vehicle has to carry into orbit, the less cargo or fuel it is able to carry due to the tyranny of the rocket equation. Composites are significantly lighter while still having the physical properties of metal, allowing for more payloads, or, crucially, more fuel for reentry burns.
