New device that emits magnetic field may offer hope for treating depression

08/05/2024
In an exploratory clinical trial, four male patients diagnosed with major depressive disorder underwent eight weeks of treatment with a device that generates a low-frequency ultralow magnetic field environment (ELF-ELME). An improvement in depressive symptoms was observed, with no adverse effects, among all patients. If the efficacy of the device can be confirmed in larger clinical trials with a control group, this therapy could serve as an alternative treatment for patients who do not want to take antidepressant medications.

Progression of herpesvirus infection remodels mitochondrial organization and metabolism

08/05/2024
Researchers have found that herpesvirus infection modifies the structure and normal function of the mitochondria in the host cell. The new information will help to understand the interaction between herpesvirus and host cells. Knowledge can be utilized in the development of viral treatments.

How a 'conductor' makes sense of chaos in early mouse embryos

08/05/2024
The earliest stages of mammalian embryo development are like an orchestra performance, where everyone must play at the exact right moment and in perfect harmony. New research identifies one of the conductors making sense of the chaos.

New super-pure silicon chip opens path to powerful quantum computers

08/05/2024
Researchers have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer.

Millions in costs due to discharge of scrubber water into the Baltic Sea

08/05/2024
Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study shows that these emissions caused pollution corresponding to socio-economic costs of more than EUR 680 million between 2014 and 2022. At the same time, the researchers note that the shipping companies' investments in the much-discussed technology, where exhaust gases are 'washed' and discharged into the sea, have already been recouped for most of the ships. This means that the industry is now making billions of euros by running its ships on cheap heavy fuel oil instead of cleaner fuel.

Bio-inspired materials' potential for efficient mass transfer boosted by a new twist on a century-old theory

08/05/2024
The natural vein structure found within leaves -- which has inspired the structural design of porous materials that can maximize mass transfer -- could unlock improvements in energy storage, catalysis, and sensing thanks to a new twist on a century-old biophysical law.

Small pump for kids awaiting heart transplant shows promise

08/05/2024
A new type of surgically implanted pump that can support a child's failing heart has passed the first stage of human testing in a recent trial.

Free-forming organelles help plants adapt to climate change

08/05/2024
Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers have now determined how these structures work on a molecular level, as well as where and how they form.

Origin of Roman lead

08/05/2024
Three ingots from the site of Los Escoriales de Do a Rama (Belmez) and dating from the Roman era demonstrate the importance of lead production and exportation in northern Cordoba.

Researchers use foundation models to discover new cancer imaging biomarkers

08/05/2024
Researchers have harnessed the technology behind foundation models, which power tools like ChatGPT, to discover new cancer imaging biomarkers that could transform how patterns are identified from radiological images. Improved identification of such patterns can greatly impact the early detection and treatment of cancer.

Caterbot? Robatapillar? It crawls with ease through loops and bends

07/05/2024
Engineers created a catapillar-shaped robot that splits into segments and reassembles, hauls cargo, and crawls through twisting courses.

Geologists, biologists unearth the atomic fingerprints of cancer

07/05/2024
Earth scientists have long turned to minute differences in hydrogen atoms to explore the ancient history of our planet. A new study suggests that these same tiny atoms might also lead to new ways to track the growth of cancer.

Venus has almost no water: A new study may reveal why

06/05/2024
Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.

DDT pollutants found in deep sea fish off Los Angeles coast

06/05/2024
As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.

Turbid waters keep the coast healthy

06/05/2024
To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study.

Past and guides future efforts to reduce cancer disparities

06/05/2024
The toll cancer takes on lives in the U.S. has declined during the last 28 years, but not equitably. Disparities persist in many historically marginalized communities -- including communities disadvantaged by race, socioeconomic status, orientation or gender identity, and geographic location -- despite community outreach and engagement programs designed to address them.

The Clues for Cleaner Water

06/05/2024
By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.

Simulated chemistry: New AI platform designs tomorrow's cancer drugs

06/05/2024
Researchers have developed a new AI tool to that generate new drug candidates for cancer, which could help streamline the typically laborious drug discovery process.

Expanding a lymph node, boosting a vaccine

06/05/2024
Researchers have found a way to enhance and extend LN expansion, and study how this phenomenon affects both the immune system and efficacy of vaccinations against tumors. While the oversized LNs maintained a normal tissue organization, they displayed altered mechanical features and hosted higher numbers of various immune cell types that commonly are involved in immune responses against pathogens and cancers. Importantly, 'jump-starting' lymph node expansion prior to administering a traditional vaccine against a melanoma-specific model antigen led to more effective and sustained anti-tumor responses in mice.

Experiment opens door for millions of qubits on one chip

06/05/2024
Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.
