Childhood disadvantage can limit the social benefits of intelligence later in life, new research shows‎

Children who grow up in disadvantaged households may receive fewer social benefits from their intelligence in adulthood than those raised in more advantaged environments, according to new research from the University of Bath. A new study by Professor Chris Dawson, published in Personality and Social Psychology Bulletin, finds that childhood disadvantage is linked not only to lower cognitive ability in adulthood, but also to lower levels of trust in other people.

Webb discovers one of the universe's first galaxies‎

Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe's first stars and is one of the most chemically primitive galaxies observed to date.

A new method could help Washington shellfish farmers control a pesky shrimp‎

Burrowing shrimp are small marine excavators native to Washington. They make their homes deep in the sediment by digging, turning the ground to Swiss cheese. This presents a problem for shellfish farmers, whose clams and oysters are often smothered under layers of displaced sediment.

Mathematical analysis reveals a hidden 'golden rule' in abstract art‎

A mathematical method borrowed from topology can reveal structural properties of visual art that correspond to how people perceive and respond to them, according to a new study published in PLOS Computational Biology by Jacek Rogala of the University of Warsaw, Poland, Shabnam Kadir of the University of Hertfordshire, UK, and colleagues.

Summers are getting longer each year, and it isn't all fun and games‎

Do you have the sense that summers feel different than when you were younger? That they start earlier, arrive quickly and remain intense until the fall? If you live in the mid-latitudes of either the Northern or Southern Hemispheres, chances are you answered yes.

A 'super El Niño?' Why it's too early to forecast one with certainty, but not too soon to prepare‎

Talk of a "super El Niño" developing in 2026 is gaining momentum, with concerns rising that this climate pattern could bring extreme rainfall, heat, drought and destructive flooding around the world.

New AI system classifies India rainfall better, cutting false alarms and missed heavy rain‎

AI can predict rainfall intensity better than several widely used forecasting models in tests using historical weather data from India. The new model reported in the International Journal of Mobile Communications shows that combining different forms of AI, along with advanced data-cleaning and optimization techniques, can make rainfall prediction more accurate and reliable, particularly when expressed in practical categories such as light, moderate, or heavy rain.

The 'Big Three' asset managers use auditor-sharing for portfolio management‎

The "Big Three" institutional investors—BlackRock, Vanguard, and State Street Global Advisors (SSGA)—have burgeoned into load-bearing pillars of the U.S. economy. With great power comes great responsibility, as well as a risk-averse investment strategy that favors common ownership—i.e., owning equity stakes in multiple companies within the same industry.

Combinations of climate extremes may prompt carbon budget rethink‎

Combined extreme climate events are likely to become more common in the future if carbon emissions continue to rise, a paper in Nature suggests. The study finds that the frequency of compound events—such as concurrent hot–wet and drought–heat extremes—is linked to cumulative carbon dioxide (CO2) emissions. In particular, the frequency of more severe events is predicted to escalate rapidly.
