832 Depression may start with an energy problem in brain cells

ScienceDaily
ScienceDaily · 03/12/2026 07:09 EDT

Researchers have discovered a surprising change in how cells produce energy in people with depression. Brain and blood cells in young adults with major depressive disorder produced more energy molecules at rest but had trouble increasing energy production when needed. Scientists believe this imbalance may contribute to symptoms such as fatigue and low motivation. The finding could help pave the way for earlier diagnosis and more personalized treatments.

Философия как основной навык будущего

К сожалению, у большинства философия ассоциируется либо с высокоабстрактными беседами ни о чем, либо с цитатами мертвых мыслителей, которые в своё время этим занимались. В то же время, реальная философия — крайне востребованный и очень практичный навык, но, к сожалению, у большинства не было возможностей его полноценно освоить на системном уровне.

Почему президенты носят одинаковые костюмы, а Цукерберг ходит в одной футболке, и как это использовать в маркетинге?

Если вы смотрите новости, то, наверняка, обратили внимание на то, что многие (если не все) президенты, премьер-министры и прочие ответственные лица носят только серые или темно-синие костюмы. Как это объяснить? Правилами этикета? Возможно… А еще Марк Цукерберг постоянно ходит в серой футболке. Вряд ли в ИТ-сообществе такие же жесткие правила поведения? В этой статье поговорим о том, как процессы принятия решений могут влиять на повседневную жизнь, маркетинг и объемы продаж... Read more

Long-forgotten ancient tablets have been decoded, uncovering a mix of magic, politics, and daily life from early civilizations. Among the discoveries are rare anti-witchcraft rituals meant to protect kings and a regnal list that could point to the real-life existence of Gilgamesh. Some texts reveal correspondence between rulers, while others show the rise of complex bureaucracies. One tablet even records something as ordinary—and relatable—as a receipt for beer. Read more

Tyrannosaurs may be famous as fearsome apex predators, but new research reveals a more opportunistic—and slightly grim—side to their behavior. Using high-resolution 3D scans, a researcher identified precise bite marks on a massive tyrannosaur foot bone, showing that a smaller tyrannosaur had fed on the remains of a much larger relative over 75 million years ago.

GLP-1 weight-loss drugs like Ozempic and Wegovy are often celebrated as game-changing solutions—but new research reveals a surprising social twist. People who lose weight using these medications may actually face more judgment than those who lose weight through diet and exercise—or even those who don’t lose weight at all. The stigma seems rooted in a perception that these drugs are an “easy way out,” creating a double bind where individuals... Read more

Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing. In animal studies, it successfully treated heart attack damage and even showed promise for conditions like traumatic brain injury and pulmonary hypertension. Unlike earlier approaches that required direct injection into the heart, this new therapy can be delivered intravenously, allowing it to spread evenly and act quickly. Read more

Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all. The object, called 2002 XV93, is far smaller than Pluto, yet observations during a rare stellar alignment revealed its presence through a subtle dimming of starlight. Even more puzzling, calculations suggest this atmosphere should vanish within about 1,000 years unless it’s... Read more

Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power. By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth. Its efficiency and small size mean it could run on batteries and be integrated into consumer electronics. This breakthrough could enable faster communications and more powerful optical technologies.

A strange kind of matter that “ticks” forever without energy input has just taken a major leap toward real-world use.

By linking the time crystal to a tiny mechanical oscillator, researchers showed they can actually control its... Read more

A surprising genetic twist shows that boosting a seemingly ordinary “housekeeping” gene can dramatically improve fruit quality without any trade-offs. By increasing the activity of a tRNA-related gene in strawberries, researchers unlocked richer color, stronger aroma, and higher levels of health-boosting compounds like anthocyanins and terpenoids. Even more striking, these enhancements came with zero impact on plant growth, fruit size, or sweetness—avoiding the usual downsides of metabolic tinkering. Read more
