A 150-million-year-old fossil discovered in China reveals a bizarre early bird with sharp teeth, a dinosaur-like claw, and a body built for life on the ground rather than flight. Scientists believe it represents the earliest known example of flight loss in birds, overturning assumptions about how these animals evolved.
Pollution from human-generated waste in marine ecosystems has reached critical levels, with cigarette butts (CBs) among the most persistent and harmful pollutants. Globally, an estimated 4.5 trillion cigarette butts are discarded annually, making them the most common type of litter on beaches over the past three decades.
Researchers at the University of Helsinki wanted to understand which is the dominant factor for species occurrence and abundance: the climate or habitat-related variables, such as their natural state and the share of land shaped by human activity. Solutions to mitigate biodiversity loss depend on the answer to this question.
Scientists discovered that the thick, sticky fluid surrounding glioblastoma tumors can make brain cancer cells smaller, more flexible, and better at invading surrounding tissue. Even more troubling, some of these changes persist after the cells leave the thick fluid, revealing a previously overlooked mechanism that could help this deadly cancer spread.
South Africa endured its worst year of load shedding (scheduled power cuts by the country's utility, Eskom) in 2023. The power went off on 335 of the year's 365 days, often several times a day. Since then, the country has gone more than a year and a half without these planned power cuts.
Researchers at the MRC Laboratory of Medical Sciences (LMS) have developed a new way to make glowing biological reporters more accurate, allowing scientists to track gene activity in living plants over days, weeks and potentially even months and years. The approach could help researchers study how plants respond to disease, pests and environmental stress, while opening the door to similar applications in animal and human disease models.
When heavy rain hits a city, knowing where water will accumulate is only part of the picture. Who lives in the affected buildings? How might flooding disrupt their lives? And where could additional support make the greatest difference?
Actor Christina Applegate was diagnosed with multiple sclerosis (MS) over five years ago — but this week, she announced that a recent reevaluation found that she doesn't have the condition after all. In the wake of that revelation, she's been left without a diagnosis, and she said on a podcast that she felt she was "back at square one, where I don't know what's going on with me."Applegate's case is not totally unique, although MS diagnosis has improved over the years. Studies offer different estimates of how frequently MS is misdiagnosed, with rates ranging from 5% to over 40%, depending on the patient population and clinical setting. There is also some degree of underdiagnosis — cases in wh...
Researchers at AIST have directly observed magnetic flux quanta generated in a superconductor by photon absorption and demonstrated a new principle of photon detection that identifies the number of photons based on the number of these flux quanta.
Masculinity content promises young men self-optimization and success, but often delivers health harms, risk-taking, unattainable standards, gender stereotypes and misogyny. The latter is the strongest predictor of violent extremism.
The new RFD4-Proteina unified generative model for protein design—created by the Institute for Protein Design (IPD) in collaboration with NVIDIA—uses advanced AI to generate entirely new protein sequences and structures, achieving computational design success rates five to 10 times higher than previous models and generating candidates five to 10 times faster.
Researchers at AIST have demonstrated the synthesis of nanoporous carbonaceous materials and carbonaceous materials with layered nanostructures through a simple process involving the chemical modification of common sugars such as sucrose and fructose.
Consumers routinely ignore information when making purchases. They overlook the tax attached to a price, skim past ingredient lists and often fail to process exact numbers with any precision.
A review by Tohoku University researchers identifies key molecular features that could guide the development of more effective materials for removing PFAS from water. The study is published in the journal ACS Materials Au.
In 1953, two physicists showed that an electron beam skimming past a grating emits light whose color depends only on the electron's speed and the grating's spacing. Known as Smith-Purcell radiation, this phenomenon has become a useful tool for building compact, tunable light sources and tracking particle beams without touching them.
The mission, scheduled for the summer of 2027, will include be pivotal in deciding whether SpaceX or Blue Origin supplies the lunar lander for the first crewed trip to the lunar surface in decades
As politics in America become more polarized and each voting cycle seems more fraught than the last, a common narrative in the media is that each election is unique and increasingly unpredictable. But new research shows that congressional elections follow strong statistical patterns, even when individual races produce surprises.
Many of the most potent antibiotics originate from bacteria. A large proportion belong to a class of compounds known as nonribosomal peptides (NRP). They are produced by large bacterial enzyme machineries—the nonribosomal peptide synthetases, or NRPS for short. These function like molecular assembly lines: Similar to the stations in a car factory, where new parts are added to the car at each step, several specialized modules string together amino acid by amino acid to build a peptide.
How can the identity of pluripotent stem cells be determined more reliably during their differentiation? Researchers from the IUF—Leibniz Research Institute for Environmental Medicine and Heinrich Heine University Duesseldorf have systematically validated marker genes for this purpose and developed a web-based application for the automated classification of early cell fates. The study has been published in Stem Cell Reports.
What if we could predict early in drug development which antibiotics bacteria are most likely to become resistant to? In a review published in Nature Reviews Microbiology, researchers from the HUN-REN Biological Research Centre, Szeged (HUN-REN BRC Szeged) and the Hungarian Centre of Excellence for Molecular Medicine (HCEMM) in Szeged propose a five-step decision-making framework that could help identify resistance risks early, refine promising drug candidates and prevent costly failures.
