How international aid fragmentation affects corruption in developing countries
An SKKU research team led by Professor Travers B. Child of the SKK Graduate School of Business (SKK GSB) has become the first in the world to use micro-level data to demonstrate that aid fragmentation—the phenomenon in which numerous international aid agencies operate
When polymers meet primitive membranes: How molecular cooperation may have helped life begin
A new study suggests that simple molecules on early Earth may have worked together to create more stable, cell-like structures, offering fresh clues about one of science's biggest questions: how life began. Led by Dr. Moran Frenkel-Pinter of Hebrew University and her
Tropical species near thermal limits as global warming compresses safety margins
With global warming and extreme weather intensifying, can animals raise their thermal tolerance to cope with a continuously warming environment? A joint research project by the Division of Science at Lingnan University and an international research team conducted experiments on
How changing environments can preserve an ancient microbial survival strategy
A research group led by Tetsuhiro Hatakeyama from the Earth-Life Science Institute (ELSI) at the Institute of Science Tokyo has revealed how a seemingly self-destructive survival strategy could persist in yeast for hundreds of millions of years. By combining population dynamics
Seabirds trade their own survival to raise more chicks after energy-intensive breeding seasons
Wild seabirds that face high energy demands during the breeding season go on to migrate farther and raise more chicks the next year, but at a cost to their own survival. An international team led by researchers from Nagoya University raised the energy cost of flight for some
Researchers develop model that predicts which Red Sea fish are most likely to invade the Mediterranean
More than 120 fish species have migrated from the Red Sea to the Mediterranean since the Suez Canal opened more than 150 years ago. Now, researchers at Tel Aviv University have developed a statistical model that can predict which species are likely to make the journey next.
Kids who own cellphones have poorer reading comprehension scores than those who don't, researchers find
School cellphone bans might seem like a good way to improve learning for elementary school children, but new research published in Behavioral Sciences shows that simply owning a cellphone correlates with worse reading comprehension. Whether a child brings the phone to school
Listening to living soil may help people reconnect with nature
Strengthening the bond between people and nature—that is the aim of a German–Dutch EU project involving Oldenburg. The reasoning behind this is that people who feel they are part of the environment are more likely to campaign for its preservation.
Molecular switch that activates cell growth signaling may offer more precise route for anticancer therapy
Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have uncovered the molecular mechanism by which amino acid signals activate this
Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal scaffolding and, in the process, release their

Cracking the code: Can AI help us decipher ancient languages?
Every ancient language that has ever been deciphered needed an anchor. Usually that's a bilingual text, like the Rosetta Stone, or a known relative to compare it to. Linear A, the writing system of the Bronze Age Minoan civilization on the Greek island of Crete, has neither.
Burning soil and peat drove most emissions in Canada's record 2023 wildfire season, study finds
Most of the carbon released during Canada's record-breaking 2023 wildfire season came from burning soil and peat, rather than trees, according to new research from McMaster University.

Research cautions that sometimes working together can actually spur inequality
Encouraging people to contribute to a common good can have a surprising drawback: a risk that rewards become concentrated among a smaller group, putting the rest at a disadvantage. Put more simply, "equality and cooperation are often in conflict," says Joshua Plotkin, Walter H.
