Decoding depression: Researchers identify crucial biomarker that tracks recovery from treatment-resistant depression

A team of leading clinicians, engineers, and neuroscientists has made a groundbreaking discovery in the field of treatment-resistant depression. By analyzing the brain activity of patients undergoing deep brain stimulation (DBS), a promising therapy involving implanted electrodes that stimulate the brain, the researchers identified a unique pattern in brain activity that reflects the recovery...

Novel photo-oxidation therapy for anticancer treatment

Scientists have achieved a significant breakthrough by inventing a new class of near-infrared-activated photo-oxidants that can effectively kill cancer cells without requiring oxygen. The photo-oxidants induce a unique form of cancer cell death that can overcome cancer cell resistance. The findings offer a new strategy, called 'photo-oxidation therapy', and provide a promising direction for the...

Genetically modifying individual cells in animals

Researchers have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments. Using the new method, the researchers have discovered genes that are relevant for a severe rare genetic disorder.

Strengthening artificial immune cells to fight cancer

Among available immunotherapies, the use of 'CAR-T' cells is proving extremely effective against certain blood cancers, but only in half of patients. A main reason for this is the premature dysfunction of these immune cells, which have been artificially modified in vitro. A team has now discovered how to prolong the functionality of CAR-T cells. By inhibiting a very specific metabolic mechanism,...

Tag team of the James Webb Space Telescope and ALMA captures the core of the most distant galaxy protocluster

An international research team has used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. The team has successfully captured the 'core region' of the galaxy protocluster, which corresponds to a metropolitan area with a particularly high number density of galaxies. The team has...

New method makes microcombs ten times more efficient

Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers have made microcombs ten times more efficient. Their breakthrough opens the way to new discoveries in space and healthcare and paves the way for high-performance lasers in a range of other...

Cognitive behavioral therapy eases how fibromyalgia pain is experienced by the brain

Patients living with fibromyalgia (FM) -- a disease that predominantly affects women and is characterized by chronic pain, fatigue and brain fog -- often find limited treatment options and a scarcity of explanations for their symptoms. Investigators have now found that cognitive behavioral therapy (CBT) can significantly reduce the burden of FM by, in part, reducing pain-catastrophizing, a...

Let it flow: Recreating water flow for virtual reality

A research team has harnessed the power of deep reinforcement learning to replicate the flow of water when disturbed. The replication allowed for recreating water flow in real time based on only a small amount of data, opening up the possibility for virtual reality interactions involving water.

Slow growth in crocodile ancestors pre-dated their semi-aquatic lifestyle

A groundbreaking study is reshaping our understanding of crocodile evolution by pinpointing the onset of slow growth rates to the Late Triassic period, much earlier than the previously assumed Early Jurassic timeline. The research highlights newly discovered fossil crocodile ancestors (known as crocodylomorphs) that exhibited slow growth rates, similar to modern-day crocodilians. Intriguingly,...

Urban light pollution linked to smaller eyes in birds

The bright lights of big cities could be causing an evolutionary adaptation for smaller eyes in some birds, a new study indicates. Researchers found that two common songbirds, the Northern Cardinal and Carolina Wren, that live year-round in the urban core of San Antonio, Texas, had eyes about 5% smaller than members of the same species from the less bright outskirts. Researchers found no eye-size...

Plant and forest researchers do not 'anthropomorphize' plants

Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.

Chameleon-inspired coating could cool and warm buildings through the seasons

As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool...

Effective visual communication of climate change

The consequences of a warming climate frequently dominated the news this summer, from devastating wildfires and floods to deadly heat waves across the globe. Reducing harm from climate change is a challenging endeavor, and it requires comprehensive public education. Thus, the question arises: How can climate change science be made most accessible to the general population, as well as...

Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers

Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully produce full-length spider silk proteins using silkworms. The findings demonstrate a technique that could be used to manufacture an environmentally friendly alternative to synthetic commercial fibers such...

Newfound brain circuit explains why infant cries prompt milk release

Hearing the sound of a newborn's wail can trigger the release of oxytocin, a brain chemical that controls breast-milk release in mothers, a new study in rodents shows. Researchers found that once prompted, this flood of hormones continues for roughly five minutes before tapering off, enabling mothers to feed their young until they are sated or begin crying again.

Reducing stress on T cells makes them better cancer fighters

Scientists discovered a relationship between the immune system's killer T cells and the body's sympathetic stress response ('fight-or-flight') in varying cancer types in mouse and human tissue samples, finding that killer T cells and sympathetic stress response hormones interact to 'exhaust' killer T cells -- but that exhaustion can be inhibited with beta-blockers. The findings demonstrate the...
