ALMA witnesses assembly of galaxies in the early universe for the first time

A team of astronomers using ALMA has detected the faint glow of ionised carbon in a galaxy just over 800 million years after the Big Bang. This finding reveals new details about the assembly of galaxies in the early universe and provides valuable information on the interstellar medium and star formation processes.

New joint military-civilian database provides insights on health care outcomes, utilization, and cost

The Person-Event Data Environment (PDE) database captures financial, health, medical and other data for every soldier from entry to separation. The database includes information on soldiers' military experience, contractors and dependents, representing a heterogeneous population with various socioeconomic backgrounds.

A cold cosmic mystery solved

Researchers discovered a massive supervoid, 1.8 billion light-years across, that could explain the unusual Cold Spot in cosmic microwave background radiation. The void's effect on light traveling through it results in colder temperatures, potentially revealing exotic physics beyond standard cosmology.

Giant galaxies die from the inside out

Astronomers observed 22 massive elliptical galaxies using the VLT and Hubble Space Telescope, revealing that star formation in their centers stopped around three billion years ago. The newly discovered inside-out nature of this shutdown may be due to a galaxy's central supermassive black hole or lack of fresh gas.

Accelerating universe? Not so fast

Researchers have found two groups of type Ia supernovae with different properties, hinting at a reevaluation of the universe's expansion rate and dark energy. The discovery uses combined observations from the Hubble Space Telescope and Swift satellite.

Integrative approaches key to understanding cancer, developing therapies, say Moffitt scientists

Moffitt scientists are using a new theory called the Big Bang model of cancer heterogeneity, which suggests that mutations occur early during tumor development. This approach has significant implications for treatments, as it recognizes that tumors can change during treatment and that current therapeutic approaches ignore this fact.

Milky Way's center unveils supernova 'dust factory'

Researchers made direct observations of cosmic dust resulting from an ancient supernova at the Milky Way's center, supporting the theory that supernovae produce dust in galaxies of the early universe. The study provides new insights into the origins of dust, a crucial component in star and planet formation.

Spreading the seeds of big data

MSU researchers are using big data analytics to help farmers adapt to climate variability, reducing nitrous oxide emissions and algal blooms. The project aims to integrate crop models with satellite imagery and UAVs to promote water-, nutrient- and climate-smart technologies.

How big data can be used to understand major events

Academics from the University of Bristol's Intelligent Systems Laboratory used big data to analyze mass media coverage of the 2012 US presidential election. The study found that the media focused more frequently on positive statements about the Democrats, while the Republicans were often portrayed in a negative light. Key issues covere...

Does a competent leader make a good friend?

Research by Lasse Laustsen and Michael Bang Petersen suggests that competent leaders are often preferred for leadership roles but not necessarily as friends. In contrast, non-dominant individuals with cooperative traits are often chosen as friends regardless of political ideology or social conflict context.

Using big data to detect disease outbreaks: Is it ethical?

The use of big data to detect disease outbreaks has the potential to strengthen global public health surveillance, but raises ethical questions about privacy, consent, and legitimacy. The authors propose a framework to address these challenges, including adapting requirements for public health contexts and ensuring methodological robus...

Cosmology: Late news from the Big Bang

New Planck analysis confirms Viatcheslav Mukhanov's theory on quantum origin of universe's structure, supporting the idea that quantum fluctuations gave rise to galaxies and clusters. The study also rules out primordial gravitational waves, suggesting that instruments may not be sensitive enough to detect them yet.

New evidence for anthropic theory that fundamental physics constants underlie life-enabling universe

A new study by Professor Ulf-G Meißner finds that fundamental physics constants are fine-tuned to allow for the emergence of a life-enabling universe. The researcher used high-performance computers to simulate worlds with altered light quark masses and found that variations up to 2-3% do not prevent the formation of carbon and oxygen.

Kent State professor publishes exact solution to model Big Bang and quark gluon plasma

A team of researchers led by Kent State professor Michael Strickland has developed an exact solution to a complex physics equation, enabling more accurate modeling of the universe's earliest moments and high-energy particle collisions. The breakthrough has far-reaching implications for fields like galactic structure, supernovae, and he...

International team maps 'big bang' of bird evolution

An international team has sequenced and compared full genomes of 48 bird species to resolve the timing and relationships of modern birds. The study suggests that only a few bird lineages survived the mass extinction event, giving rise to the 10,000 Neoaves species that comprise 95% of all bird species.

Penrose's and Hawking's early math award revisited

In 1966, Roger Penrose won the prestigious Adams Prize for his essay on space-time structure, while Steven Hawking received an auxiliary prize for his essay on singularities and spacetime geometry. These early awards laid the foundation for their later work on cosmology and black holes.

Self-inflation harms kids' relationships at school

A new study by Katrin Rentzsch and Michela Schröder-Abé found that unrealistic views of one's academic abilities can damage a child's relationship with others in the classroom. Students who tend to feel unrealistically superior to their peers are less liked by them, even at habitual levels.
