The early roots of carnival? Research reveals evidence of seasonal celebrations in pre-colonial Brazil
2025-02-05
Pre-colonial people in Brazil may have gathered in summer months to feast on migratory fish and share alcoholic drinks, a new study suggests.
An international team – involving scientists from the University of York, UK; the Universitat Autònoma de Barcelona, Spain, and the Universidade Federal de Pelotas in Brazil – analysed pottery fragments dating back to between 2300 and 1200 years ago which were discovered around the Patos Lagoon in Brazil.
The shores of the Lagoon are characterised by settled earthen mounds, known as “Cerritos” which were built by pre-colonial ancestors of Pampean Indigenous ...
Meteorite discovery challenges long-held theories on Earth’s missing elements
2025-02-05
Understanding where Earth’s essential elements came from—and why some are missing—has long puzzled scientists. Now, a new study reveals a surprising twist in the story of our planet’s formation.
A new study led by Arizona State University’s Assistant Professor Damanveer Grewal from the School of Molecular Sciences and School of Earth and Space Exploration, in collaboration with researchers from Caltech, Rice University, and MIT, challenges traditional theories about why Earth and Mars are depleted in moderately volatile elements (MVEs). MVEs like copper and zinc play a crucial role in planetary chemistry, often accompanying life-essential ...
Clean air policies having unintended impact driving up wetland methane emissions by up to 34 million tonnes
2025-02-05
Reducing sulphur in the air may inadvertently increase natural emissions of methane from wetlands such as peatlands and swamps, a new study has found.
The findings published today in the journal Science Advances suggests that the decline of global sulphur emissions as the result of clean air policies, coupled with the warming and fertilization effects of carbon dioxide emissions lifts a lid on wetland methane production resulting in increased emissions.
The resulting additional future release of 20-34 ...
Scientists simulate asteroid collision effects on climate and plants
2025-02-05
A new climate modeling study published in the journal Science Advances by researchers from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid.
The solar system is full of objects with near-Earth orbits. Most of them do not pose any threat to Earth, but some of them have been identified as objects of interest with non-negligible collision probabilities. Among them is the asteroid Bennu with a diameter of about 500 m, which, according to recent studies ...
The Wistar Institute scientists discover new weapon to fight treatment-resistant melanoma
2025-02-05
PHILADELPHIA — (February 5, 2025) —The lab of The Wistar Institute’s Jessie Villanueva, Ph.D., has identified a new strategy for attacking treatment-resistant melanoma: inhibiting the gene S6K2. The team published their findings in the paper, “Selective abrogation of S6K2 identifies lipid homeostasis as a survival vulnerability in MAPKi-resistant NRASMUT melanoma,” from the journal Science Translational Medicine.
“This work shows that, even in the face of notoriously ...
Fool yourself: People unknowingly cheat on tasks to feel smarter, healthier
2025-02-05
UNIVERSITY PARK, Pa. — Fool me once, shame on you. Fool myself, and I may end up feeling smarter, according to a new study led by Sara Dommer, assistant professor of marketing at Penn State.
Dommer wondered why people cheat on tasks like completing crossword puzzles or Wordle and counting calories when the rewards are purely intrinsic, like feeling smarter or healthier. She found that when cheating offers the opportunity to improve self-perception, individuals engage in diagnostic self-deception — that is, they cheat yet deceive themselves by attributing their heightened performance to their innate ability instead ...
Rapid increase in early-onset type 2 diabetes in China highlights urgent public health challenges
2025-02-05
A new study led by researchers from Peking University, published in Health Data Science, reveals a sharp rise in the burden of early-onset type 2 diabetes (T2D) among adolescents and young adults in China from 1990 to 2021. Despite improvements in mortality rates, the incidence and disability-adjusted life years (DALYs) associated with the disease have grown alarmingly.
Using data from the Global Burden of Disease (GBD) Study 2021, the study shows that the age-standardized incidence rate nearly doubled, increasing from 140.20 per 100,000 in 1990 to 315.97 per 100,000 in 2021, with an average annual percentage change ...
Researchers discover the brain cells that tell you to stop eating
2025-02-05
NEW YORK, NY (Feb. 5, 2025)--Columbia scientists have found specialized neurons in the brains of mice that order the animals to stop eating.
Though many feeding circuits in the brain are known to play a role in monitoring food intake, the neurons in those circuits do not make the final decision to cease eating a meal.
The neurons identified by the Columbia scientists, a new element of these circuits, are located in the brainstem, the oldest part of the vertebrate brain. Their discovery could lead ...

Firearm type and number of people killed in publicly targeted fatal mass shooting events
2025-02-05
About The Study: This study found that most publicly targeted fatal mass shootings involved multiple types of firearms and handguns were the most common type of firearm present. Assault weapons being present during a publicly targeted mass shooting was associated with a slight increase in the number of injuries and deaths occurring during that incident.
