Moving up in the world: Rare catfish species filmed climbing waterfalls

Nature often puts on incredible displays. A recent example caught on camera shows thousands of bumblebee catfish (Rhyacoglanis paranensis) climbing waterfalls in southern Brazil. This is the first time the species has been observed in such a large group and climbing, according to a study published in the Journal of Fish Biology describing the spectacle.

Environmental Military Police from Mato Grosso do Sul State spotted the catfish scaling slippery rocks between one and four meters high behind waterfalls on the Aquidauana River. The sighting occurred in November 2024 at the beginning of the rainy season, and a week later, a team of Brazilian scientists arrived to document the event.

They observed that the catfish’s climbing behavior depended on the time of day. During the hot afternoons, the fish sheltered under rocks and in shaded areas. They began climbing in the early evening as the sun was setting. The researchers also studied how the fish are able to climb. They keep their paired fins wide open and use lateral and caudal movements to push themselves forward. Scientists believe this is also aided by a suction mechanism that helps them stick to flat surfaces.

Human embryo implantation recorded in real time for the first time

Researchers at the Institute for Bioengineering of Catalonia (IBEC) in collaboration with the Dexeus University Hospital have captured unparalleled images of a human embryo implanting. This is the first time that the process has been recorded in real time and in 3D.

Intergalactic experiment: Researchers hunt for mysterious dark matter particle with clever new trick

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

Complex deep learning models are no better at understanding genetic perturbation than simple baseline ones, study finds

Deep learning models have shown great potential in predicting and engineering functional enzymes and proteins. Does this prowess extend to other fields of biology as well?

Using Grover’s algorithm to efficiently prepare collective quantum states in optical cavities

The reliable engineering of quantum states, particularly those involving several particles, is central to the development of various quantum technologies, including quantum computers, sensors and communication systems. These collective quantum states include so-called Dicke and Greenberger-Horne-Zeilinger (GHZ) states, multipartite entangled states that can be leveraged to collect precise measurements, to correct errors made by quantum computers and to enable communication between remote devices leveraging quantum mechanical effects.

A new crystal that ‘breathes’ oxygen expands possibilities for clean energy and electronics

A team of scientists from Korea and Japan has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices.

Long-term transcranial magnetic stimulation plus language therapy may slow aphasia progression

Hospital Clínico San Carlos in Madrid-led research reports that intermittent theta-burst transcranial magnetic stimulation (TMS) paired with language therapy over six months was associated with positive outcomes in primary progressive aphasia (PPA). Improvements included less decline in regional brain metabolism and improvements in language abilities, functional independence, and neuropsychiatric symptoms.

Primary progressive aphasia is a neurodegenerative clinical syndrome with insidious onset characterized by prominent speech and/or . It is a syndrome that can be the mode in which common causes of dementia, Alzheimer’s disease and frontotemporal degeneration are initially present.

According to current international consensus criteria, three variants are recognized: nonfluent/agrammatic, semantic, and logopenic. Speech-language intervention has proven to be beneficial.

Unified theory may reveal more superconducting materials

Electricity flows through wires to deliver power, but it loses energy as it moves, delivering less than it started with. But that energy loss isn’t a given. Scientists at Penn State have found a new way to identify types of materials known as superconductors that allow power to travel without any resistance, meaning no energy is lost.

Chemical tag CRISPR technique could transform genetic disease treatment

A new generation of CRISPR technology developed at UNSW Sydney offers a safer path to treating genetic diseases like sickle cell, while also proving beyond doubt that chemical tags on DNA—often thought to be little more than genetic cobwebs—actively silence genes.

Visual thalamus reshapes information beyond simple relay function, study finds

When you see something—a tree in your backyard, say, or the toy your toddler hands you—that visual information travels from your retinas to your brain. And like a train stopping at stations along its route, the information pauses at particular regions of the brain where it’s processed and sent along to its next location.

A region called the visual thalamus has been thought to be primarily a relay, simply directing to its next area. But a new study published in Neuron finds that the thalamus actually integrates additional information from other and reshapes the information it sends along to the brain cortex.

Liang Liang, Ph.D., assistant professor of neuroscience at Yale School of Medicine (YSM) and senior author of the study, suspected the thalamus might be doing more than it had been given credit for.
