Feather found in dinosaur poop may explain how birds survived the asteroid that killed dinosaurs
The 66-million-year-old feather found inside fossilised dinosaur poop may offer clues about why some birds survived the asteroid impact that killed most dinosaurs. Researchers found feathers, fish scales and bird bones in the coprolite. The feather’s primitive structure suggests insulation and moulting may have played a role in determining which birds survived.
Scientists used centuries-old aurora sightings: their method placed solar minima within 2 years with more than 90% reliability
Ancient auroras are unlocking secrets of solar activity, offering scientists a glimpse into the Sun's behavior long before our time. By employing a new statistical method to analyze historical sky observations, researchers have pieced together eight distinct cycles of solar activity from 1560 to 1640. This intriguing study correlates well with various independent solar records, enhancing our understanding of solar dynamics pre-dating contemporary measurements.
MIT makes water filters from tree branches that remove over 99% of bacteria and viruses
MIT engineers have pioneered an eco-conscious method of producing water filters from tree sapwood. These natural filters successfully eradicate more than 99% of bacteria and viruses found in water. During testing in India, researchers worked closely with local populations to create a user-friendly prototype that is both effective and cost-efficient. This sustainable solution is poised to enhance access to clean drinking water in numerous communities.
Scientists collected spider webs in Australia; their DNA revealed vertebrate species nearby
Researchers have discovered that spider webs serve as fascinating collectors of genetic material from nearby vertebrates. In a comprehensive study in Australia, vertebrate DNA was detected across all samples, providing insights into thirty-two species at sanctuaries and sixty-one at zoos. The quantity of detectable DNA varied with animal size and distance, hinting that webs could offer an innovative approach to monitoring wildlife without the need for direct interaction.
Scientists removed trout from a California lake, and wildlife began to recover
The introduction of trout in Sierra Nevada lakes has had a noteworthy impact on bird populations, leading to a reduction in their numbers. The fish also changed the diversity of bird species present near the water. Additionally, mayflies, an essential part of the birds' diet, declined in lakes with trout.
Scientists asked volunteers to live like earthworms and kestrels to rethink human landscapes
A project involved volunteers experiencing wildlife senses near the River Tone. Participants observed risks to red deer, otters, and other animals. They identified threats like dog activity and train noise impacting wildlife. This approach helps recognize overlooked environmental dangers to animals. The methodology will be used in other communities and settings.
India needs to launch the space act it keeps scrubbing
As India's space industry develops, it urgently needs a Space Act to provide stringent legal support. Initiated in 2020, the opening of this sector, alongside the establishment of IN-SPACe, has highlighted gaps in existing policies. A robust Space Act would not only outline company rights but also enhance regulatory clarity, paving the way for the sector's growth and improved global positioning.
Skeleton Found In Roman Jar: archaeologists uncover 1,600-year-old victim; find hints of desperate escape
In a remarkable excavation at Deultum, Bulgaria, archaeologists uncovered the remains of a young man entombed within a sizable storage jar. The evidence indicates he sought refuge there during a devastating attack, likely after the flames had already engulfed the area. His plight, frozen in time as the jar was later rebuilt over, provides a poignant glimpse into the terror and desperation of ancient times.
