Mature sperm lack intact mitochondrial DNA, study finds
New research provides insight about the bedrock scientific principle that mitochondrial DNA—the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body—is exclusively passed down by the mother......»»
New CRISPR system for gene silencing doesn"t rely on cutting DNA
Scientists from Vilnius University's (VU) Life Sciences Center (LSC) have discovered a unique way for cells to silence specific genes without cutting DNA. This research, led by Prof. Patrick Pausch and published in the journal Nature Communications,.....»»
53 years of survey data confirm African elephant decline
Habitat loss and poaching have driven dramatic declines in African elephants, but it is challenging to measure their numbers and monitor changes across the entire continent. A new study has analyzed 53 years of population survey data and found large-.....»»
Swirling polar vortices likely exist on the sun, new research finds
Like the Earth, the sun likely has swirling polar vortices, according to new research led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR). But unlike on Earth, the formation and evolution of these vortices.....»»
Was "Snowball Earth" a global event? New study delivers best proof yet
Geologists have uncovered strong evidence from Colorado that massive glaciers covered Earth down to the equator hundreds of millions of years ago, transforming the planet into an icicle floating in space......»»
Windfall profits from oil and gas could cover climate payments, says study
A central issue at the UN Climate Change Conference, set to start on November 11, will be the negotiations on new payments from industrialized nations to poorer countries. However, the question of whether and how these payments will be financed remai.....»»
Inland Delaware watersheds impaired by human waste, study suggests
Delaware has numerous inland waterways with high microbial impairment from unknown sources. Now, a new study suggests that human waste, both treated and untreated, is responsible for the waterway impairment in these Delaware watersheds. The study was.....»»
Hypercarnivores study reveals unique adaptations of jaw function and tooth wear
A new study led by Dr. Jack Tseng, published in PeerJ, has shed light on the intricate relationship between tooth wear and jaw mechanics in highly carnivorous mammals, known as hypercarnivores......»»
Arctic raptors study reveals a new migration pattern, highlighting potential errors in range mapping
Traditionally, migratory birds are thought to arrive at their wintering grounds after fall migration and remain there until the spring migration back to breeding sites. This assumption forms the basis for determining over-wintering ranges and shaping.....»»
New AI model improves prediction power for genomics related to disease
To understand the workings of DNA in relation to disease, scientists at Los Alamos National Laboratory have developed the first multimodal deep learning model of its kind, EPBDxDNABERT-2, capable of ascertaining the precise relationship between trans.....»»
Weather extremes influence illegal migration and return between the U.S. and Mexico, study finds
Extreme weather is contributing to undocumented migration and return between Mexico and the United States, suggesting that more migrants could risk their lives crossing the border as climate change fuels droughts, storms and other hardships, accordin.....»»
Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated period of over thr.....»»
Retirees should invest bolder as they grow older, study suggests
Retirement is a longed-for milestone in most workers' lives, but the transition requires a delicate financial balance. Retirees must anticipate life expectancy, inflation, recurring expenses and more as they manage their investments to ensure their l.....»»
Laser spectroscopy study explores nuclear structure of fermium and nobelium isotopes
University of Liverpool researchers are part of an international research collaboration that has shed light on what happens at the extremes of neutron and proton numbers, in search of where the periodic table of chemical elements ends......»»
Private jet carbon emissions soar 46%: Study
The carbon footprint from private jet travel grew 46 percent between 2019 and 2023 and will keep rising unless the ultra-luxury industry is regulated, according to new research published Thursday......»»
New DNA evidence rewrites long-told stories of people in ancient Pompeii
When a volcanic eruption buried the ancient city of Pompeii, the last desperate moments of its citizens were preserved in stone for centuries......»»
Implementing topologically ordered time crystals on quantum processors

Making Australia"s growing cities more sustainable
The way we organize our cities and regions creates problems everywhere. We're facing difficult and polluting drives to work, a lack of affordable housing, and urban designs that lead to car dependency and are bad for our health......»»
New Apple Vision Pro study reveals promising performance in radiology
A new study published this week by researchers at the University of California, San Diego highlights how Apple Vision Pro can be used in healthcare settings. In particular, this study sought to compare diagnostic performance when using Apple Vision P.....»»
DNA shows Pompeii’s dead aren’t who we thought they were
Integrating genetic data with historic and archaeological data can enrich or correct popular narratives. People have long been fascinated by the haunting plaster casts of the bodi.....»»
Mitochondrial study offers new insights into how our cells process RNA for energy production
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have made a major discovery in how human cells produce energy. Their study, published in The EMBO Journal, reveals the detailed mechanisms of how mitochondria process.....»»
