Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
Who lives in the rainforest treetops? DNA-collecting drone provides insights
Squinting into the treetops won't reveal the tiny organisms up there. But these creatures leave clues, in the form of DNA, on the leaves and branches. Now, researchers report in Environmental Science & Technology that they have developed a way to col.....»»
Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
Do you feel eco-guilt or eco-shame? Emotions reveal how much we care about the environment
Air travel, meat in the shopping cart, waste sorting, plastic toys—consumers are faced with a barrage of everyday decisions and priorities when navigating environmental concerns. But what drives these choices?.....»»
New insights into hot carrier solar cells: Study explores hot electron tunneling and collection to enhance efficiency
Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley–Queisser efficiency limit, which is a theoretical maximum efficien.....»»
Mechanism behind autophagy trigger unveiled
An international research team led by Osaka University has identified a new mechanism crucial for the initiation of autophagy, a self-degradation process cells use to eliminate unneeded or damaged components. In recent years, autophagy has also been.....»»
Yeast chit-chat: How microorganisms communicate food shortages
To grow and survive, tiny organisms such as yeast must sometimes adapt their nutrient sources in response to changes in the environment. FMI researchers have now found that yeast cells communicate with each other to use less favorable nutrients if th.....»»

Archaeologists have analyzed textiles from the ancient city of Huacas de Moche, Peru, showing how the population's cultural traditions survived in the face of external influence......»»
Businesses trying to come clean about their impact on nature can end up concealing more than they reveal
Humans have overfished the ocean, cleared forests, polluted water and created a climate crisis by burning fossil fuels. These actions are affecting biodiversity around the world, from remote islands to our own backyards......»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Educators and parents reveal culture of fear, censorship, and loss of learning opportunities in wake of FL policies
