New analyses of giant fossilized megalodon teeth are helping scientists unravel the mystery of their extinction
Millions of years ago, giant sharks three times larger than today's great whites stalked the world's ocean. They're long gone now, but occasionally, someone walking on a beach spots an odd triangular shape in the sand. On closer inspection, they real.....»»
Scientists calculate predictions for meson measurements
Nuclear physics theorists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made.....»»
Climate change is contributing to drought in the American West even without rainfall deficits, scientists find
Higher temperatures caused by anthropogenic climate change made an ordinary drought into an exceptional drought that parched the American West from 2020–2022. A study by UCLA and National Oceanic and Atmospheric Administration climate scientists ha.....»»
Hands-on: iOS 18.2 beta 2 changes and features [Video]
The initial beta for iOS 18.2 brought forth a heaping helping of new changes and features, headlined by phase two of the Apple Intelligence rollout. In the second beta, Apple continues to build on Apple Intelligence, but we also find several other no.....»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Scientists use high-energy heavy ion collisions as a new tool to reveal subtleties of nuclear structure
Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE's Brookhaven National La.....»»
Expecting again? Tips for helping your first-born child thrive with a new sibling
Expecting another child can be both exciting and nerve-racking. Many parents feel more confident the second (or third) time around as they have already experienced the birthing process, the challenges of caring for a newborn and the inevitable sleep.....»»
Bioinspired hydrogels harness sunlight: A step closer to artificial photosynthesis
Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature's method, using sunlight to drive chemical react.....»»
New research may lead to potatoes that are less reliant on nitrogen fertilizers
Because nitrogen fertilizers contribute to global greenhouse gas emissions, scientists are looking for ways to modify agricultural plants so that they rely on less nitrogen. In research published in New Phytologist, investigators have found that bloc.....»»
Braving sharks and hordes of urchins, scientists are growing kelp one forest at a time
The weathered UC Davis Marine Laboratory looms in thick fog on the edge of the ocean near Bodega Bay. Inside, an experiment is playing out that gives a badly-needed boost to Northern California's kelp forests—underwater cathedrals of green and gold.....»»
New framework uses games of chance to put "price" on intangible assets
A new statistical model could help to address the age-old question of how to price non-physical, intangible goods like data, say scientists......»»
Bach, Mozart or jazz: Scientists provide a quantitative measure of variability in music pieces
Physicists at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have investigated to which extent a piece of music can evoke expectations about its progression. They were able to determine differences in how far compositions of dif.....»»
Scientists find key to engineering water-responsive biopolymers
Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have developed a novel approach to better understand and predict the behaviors of water-responsive materials—solid matter that can change shape by absorbing.....»»
New modeling of complex biological systems could offer insights into genomic data and other huge datasets
Over the past two decades, new technologies have helped scientists generate a vast amount of biological data. Large-scale experiments in genomics, transcriptomics, proteomics, and cytometry can produce enormous quantities of data from a given cellula.....»»
Helping the most vulnerable stay cool in extreme heat
The health effects of heat waves hit some communities harder than others. People with preexisting health conditions, as well as those who have low income or are physically or socially isolated, very old or very young, from racial or ethnic minority g.....»»
Scientists shed light on an arms race between barley and a fungal pathogen
Scientists from the Leibniz Institute of Plant Biochemistry (IPB), together with partners from the University of Cologne, have discovered a new group of defense substances in barley that are effective against a broad spectrum of fungal pathogens. One.....»»
New plant bug species discovered in French Polynesia
Seventeen new species of plant bugs—a group of insects with a strawlike mouth used to feed on plant and animal matter—have been identified on the islands of French Polynesia, and their names honor scientists, actors, and Vice President Kamala Har.....»»
Scientists have figured out why Martian soil is so crusty
On November 26, 2018, NASA's Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) mission landed on Mars. This was a major milestone in Mars exploration since it was the first time a research station had been deplo.....»»
Another season of highs and lows as 2024 Australian humpback migration ends
