Police got called to an overcrowded presentation on “rejuvenation” technology
Biologists trying to create laboratory models of the early growth of a human embryo have taken a major step forward. In preprints posted online on Thursday and Friday, four research teams reported using various kinds of human stem cells, some genetically modified, to create ersatz embryos that closely resemble real embryos that are up to 14 days old, replicating a period in human...
Bad break-up in warm waters: Why marine sponges suffer with rising temperatures
It’s not every day that police storm through the doors of a scientific session and eject half the audience.
But that is what occurred on Friday at the Boston Convention and Exhbition Center during a round of scientific presentations featuring Juan Carlos Izpisua Belmonte, a specialist in “rejuvenation” technology at a secretive, wealthy, anti-aging startup called Altos Labs....
Are aliens that bad at parking? What we need to ask about recent UFO revelations
Marine sponges have started dying in vast numbers in coastal areas around the globe. Just this year, thousands of sponges turned white and died in New Zealand and in the Mediterranean Sea. This has been happening when the water gets too warm, but the underlying cause has remained a mystery. Until now.
Slowing deep Southern Ocean current may be linked to natural climate cycle—but melting Antarctic ice is still a concern
Recent claims by an ex-US intelligence agency whistleblower about alien spacecraft landings have been met with scepticism by scientists – not least over the galactic visitors’ driving skillsAnother day, another story about the US government hiding the fact that it has retrieved alien spacecraft. You can hear similar claims all the time from conspiracy theorists in certain corners of the...
Light pollution is taking the sparkle out of glow-worm mating
Our new research in the Antarctic suggests that the vital layer of cold water on the sea bed, which circulates the globe and influences the ocean's ability to continue absorbing much of the rise in atmospheric heat and greenhouse gas emissions, is heating up and shrinking.
To fight berry-busting fruit flies, researchers focus on sterilizing the bugs
The invention of electric light has extended our lives deeper into the night: street lamps help us travel more safely outdoors, while lighting indoors lets us work and play for longer. Entire stadiums are drenched in light so that people can watch sport at night. Even your garden may be lit up to accentuate its finer features.
There Are Amazing Fathers in the Animal Kingdom
Paul Nelson is used to doing battle with an invasive fruit fly called the spotted wing drosophila, a pest that one year ruined more than half the berries on the Minnesota farm he and his team run. In recent years, they've cut their losses closer to 5%, but it's been labor-intensive and expensive.
New tracking device to keep better tabs on wolves
Why treat fatherhood as a miracle?
This was my question when Murphy, a bald eagle, became a viral sensation for being a great stepdad. At first, Murphy tried to incubate a rock at the World Bird Sanctuary in Valley Park, Missouri. When the sanctuary received an eaglet that had dropped out of its nest, they allowed Murphy to move from rock-sitting to actual offspring care. He did so well that the...
What to do when you spot a whale that's washed ashore
Keeping up with the journeys of wolves and welfare of wild horses has never been easier. With a GPS wildlife tracker powered by an animal's own movements, University of Copenhagen researchers have solved a problem faced by biologists and wildlife managers seeking to track wild animals year after year: dead batteries.
Nanoparticles deliver small interfering RNA to slow multiple myeloma
When whales wash ashore, it might be people's first instinct to help push them back in the water. It is the wrong course of action, says an official with the Nova Scotia-based Marine Animal Response...
Remains of new species of duck-billed dinosaur found in Chile
Research led by the University of Pennsylvania, Philadelphia, has used siRNA-based silencing of protein cyclophilin A (CyPA) to reduce tumor burden and extend the lives of patients with multiple myeloma.
Climate warming pits geese against farmers in Finland
Remains of a species of herbivorous dinosaur previously unknown in the southern hemisphere have been discovered in Chile, challenging long-held beliefs about the range of duck-billed dinosaurs, scientists said Friday.
With a cacophony of honks sounding like a hailstorm, tens of thousands of hungry geese blanket a lush green field in Finland with their black flocks.
