Deciphering crosstalk between bFGF and integrin signaling in maintaining properties of hiPSCs
A research team led by Junior Associate Professor Masato Nakagawa (Department of Life Science Frontiers) investigated the effects of basic fibroblast growth factor (bFGF) and its interactions with fibroblast growth factor receptors (FGFRs) and integr.....»»
Big planets don"t necessarily mean big moons
Does the size of an exomoon help determine if life could form on an exoplanet it's orbiting? This is something a February 2022 study published in Nature Communications hoped to address as a team of researchers investigated the potential for large exo.....»»
Study of wide binary stars reveals new evidence for modified gravity at low acceleration
A new study published in The Astrophysical Journal reveals new evidence for standard gravity breaking down in an idiosyncratic manner at low acceleration. This new study reinforces the evidence for modified gravity that was previously reported in 202.....»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»
Carnivorous plant traps help scientists explain the evolution of complex "composite" traits
An international team of researchers led by Dr. Ulrike Bauer from the University of Bristol investigated two tropical pitcher plant species separated by 4,000 km of open ocean: The Slender Pitcher Plant (Nepenthes gracilis) found in Borneo, and Nepen.....»»
Hunting for elusive tetraneutrons with thermal fission
The possible emission rate of particle-stable tetraneutron, a four-neutron system whose existence has been long debated within the scientific community, has been investigated by researchers from Tokyo Tech. They looked into tetraneutron emission from.....»»
Pulsations detected from the XZ Ursae Majoris system
Astronomers have conducted a photometric and spectroscopic study of an Algol-type binary, known as XZ Ursae Majoris (or XZ UMa for short). Results of the study, presented in a paper published December 21 on the pre-print server arXiv, indicate that t.....»»
New ultra-short period binary discovered
Using the Tsinghua University–Ma Huateng Telescopes for Survey (TMTS), an international team of astronomers has discovered a new binary known as TMTS J052610.43+593445.1. The newfound system is an ultrashort-orbital-period binary consisting of a su.....»»
Zwicky Transient Facility detects four ultracompact binaries
By investigating dwarf novae identified by the Zwicky Transient Facility (ZTF), astronomers have discovered four binary systems. The objects turned out to be eclipsing accreting ultracompact white dwarf binaries. The finding was reported in a paper p.....»»
Indian astronomers explore open cluster NGC 6940 with AstroSat
Using the AstroSat spacecraft, astronomers from the Birla Institute of Technology and Science in Pilani, India, have investigated a nearby open cluster NGC 6940. Results of the observational campaign, published December 21 on the pre-print server arX.....»»
Shedding light on the origin of the photovoltaic effect in organic–inorganic perovskites
A team led by RIKEN researchers has investigated how special crystals convert light into electricity. Their findings will help inform efforts to improve their efficiency, which could lead to the crystals being used in solar cells. The study is publis.....»»
New research reveals how to obtain high-quality DNA from marine samples
The oceans are still the most underexplored part of our planet. Diversity of large organisms in the Arctic Ocean has been investigated in many ways, yet research on the diversity of Arctic microorganisms is lacking. One of the problems, apart from in.....»»
Big impacts from small changes: Research reveals how filament interactions affect cellular networks
Tiny things matter—for instance, one amino acid can completely alter the architecture of the cell. Researchers at the Universities of Göttingen and Warwick investigated the structure and mechanics of the main component of the cell's cytoskeleton:.....»»
Investigating how microbial interactions shape Cheddar cheese"s flavor profile
The combinations of microorganisms responsible for shaping the taste of Cheddar cheese—including fruity, creamy, buttery, and nutty flavors—are investigated in a Nature Communications paper......»»
Young open cluster Messier 39 investigated in detail
Italian astronomers have performed high-resolution spectroscopic observations of a young open cluster known as Messier 39. Results of the observational campaign, presented in a paper published Dec. 14 on the pre-print server arXiv, yield essential in.....»»
Study finds fires of war overtook climate-controlled fires along the eastern Silk Road
Human activities such as intentional burning, agriculture, pastoralism, and metallurgy can affect the frequency of fire in an ecosystem. Guanghui Dong, Aifeng Zhou and colleagues investigated whether another typical human activity has influenced fire.....»»
Study shows how vertebrates shape the North Sea seafloor
The world's oceans are a vast habitat for countless creatures that settle, spawn, dig or feed on the seafloor. They also influence the shape of the ocean floor. How exactly this takes place has scarcely been investigated......»»
Astronomers discover first population of binary stripped stars
Astronomers at the University of Toronto have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings, published in Science, shed light on the hot helium stars t.....»»
