High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact within these droplet-like structures. The findings connect molecular architecture to the broader behaviors of these droplets in cells.
Scientists uncover a volcanic trigger behind the Black Death
A newly analyzed set of climate data points to a major volcanic eruption that may have played a key role in the Black Death’s arrival. Cooling and crop failures across Europe pushed Italian states to bring in grain from the Black Sea. Those shipments may have carried plague-infected fleas. The...
Researchers solve a century-old North Atlantic cold spot mystery
A century-old North Atlantic cold patch is now linked to a long-term slowdown in the AMOC, the climate-regulating conveyor belt of ocean water. Only weakened-AMOC models match observed temperature and salinity patterns, overturning recent model trends. This slowdown affects weather systems, jet streams, and marine life throughout the Northern Hemisphere....
Scientists keep a human alive with a genetically engineered pig liver
Researchers successfully implanted a genetically modified pig liver into a human, proving that such an organ can function for an extended period. The graft supported essential liver processes before complications required its removal. Although the patient ultimately passed away, the experiment demonstrates both the potential and the complexity of xenotransplantation....
Scientists reveal a surprising new timeline for ancient Egypt
A new radiocarbon study has clarified the timing of the colossal Thera eruption, placing it before Egypt’s New Kingdom. Researchers analyzed artifacts tied to Pharaoh Ahmose, gaining rare access to museum materials. Their results favor a younger chronology for early 18th Dynasty Egypt. The revised timeline reshapes regional historical connections.
A massive Bronze Age city hidden for 3,500 years just surfaced
An immense Bronze Age settlement has emerged from the Kazakh Steppe, revealing a surprisingly urban and industrial society where archaeologists once expected nomadic camps. At Semiyarka, researchers uncovered massive residential compounds, a possible ceremonial or administrative building, and an entire industrial zone dedicated to producing tin bronze—an extremely rare discovery...
A mysterious black snake hidden for centuries is now named for Steve Irwin
Researchers have uncovered a new species of wolf snake on Great Nicobar Island and named it Lycodon irwini in tribute to Steve Irwin. The glossy black, non-venomous snake grows up to a meter and appears confined to a small area. Scientists warn its limited habitat makes it vulnerable. The find...
Earth’s early oceans hid the secret rise of complex life
Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features emerged in ancient anoxic oceans long before oxygen became a major part of Earth’s atmosphere. Their results indicate that early complexity developed slowly...
New Study Finds That Drones Can be a Valuable Ally in Elephant Conservation
Once seen as a source of alarm, drones (or Unmanned Aerial Vehicles, UAVs) are now proving to be surprisingly elephant-friendly and a valuable research tool.
Distance From Natural Habitat Doesn’t Reduce Pollination in Tropical Smallholder Farms
Being close to a natural habitat such as a forest doesn’t necessarily make farmland more attractive to pollinators, a new study shows.
