Guiding Electricity Through the Air Using Ultrasound Pulses

Material & Energy, Renewable Energy, Tech /

Electricity is naturally unpredictable, typically requiring wires and circuits for control. However, researchers in Europe and Canada have successfully directed sparks through open air and around obstacles using ultrasound waves. In open air, electricity naturally spreads in unpredictable directions—much like a lightning bolt. Its path is influenced by slight variations in air density, charge distribution, […]

How Depression Alters Your Appetite and Boosts Carb Cravings

Space & Environment /

Depression impacts about 280 million people globally and is known to affect eating habits. A recent study from researchers at University Hospital Bonn (UKB), the University of Bonn, and University Hospital Tübingen reveals that while people with depression often experience a reduced appetite, they tend to crave carbohydrate-rich foods. The study, published in Psychological Medicine,

Chance of a Tunguska-Level Impact in 2032 Has Now Doubled

Space & Environment /

At the end of 2024, astronomers spotted a new asteroid in the night sky. It was designated 2024 YR4—”Y” for its December discovery, “R4” as the 117th rock found in late December, and “2024” marking the year of detection. Once identified, astronomers began tracking its position to refine its orbit. Initial calculations suggested a 1%

A Mysterious Cosmic Explosion May Have Been Detected

Space & Environment /

A mysterious cosmic explosion has left astronomers baffled, presenting either an incredibly rare cosmic alignment or an entirely new phenomenon. The event, labeled EP240408a, was first detected on April 8, 2024, by the Einstein Probe, an X-ray space telescope. Initially, it resembled a typical gamma-ray burst, known for its bright X-ray emissions. However, follow-up observations

Study Finds Common Root Cause Behind Multiple Psychiatric Disorders

Health & Fitness /

Researchers recently found that eight psychiatric disorders share a common genetic foundation. A new study has pinpointed specific genetic variants involved, revealing that many remain active longer during brain development. This extended activity suggests they influence multiple developmental stages, making them potential targets for treating multiple conditions. “The proteins produced by these genes are highly

Beyond the Uncanny Valley: New Technology Brings Robots to Life

Tech /

Osaka University researchers have developed a technology that enables androids to express moods like excitement or drowsiness through dynamic facial movements modeled as overlapping, decaying waves. While androids can mimic human expressions, their movements often feel artificial, creating discomfort. Traditional approaches rely on pre-programmed action sequences, requiring complex preparation and careful transition management to avoid

Nasal Fungi May Be Aggravating Your Allergies

Health & Fitness /

Allergic rhinitis and asthma, often linked, can severely impact respiratory health. Searching for better treatments, scientists analyzed the nasal mycobiome—the community of fungi in the nose. Their study revealed that individuals with allergic rhinitis, with or without asthma, have distinct fungal compositions compared to healthy individuals. This suggests chronic respiratory conditions may disrupt nasal fungi

Certain Drugs May Reduce Dementia Risk—A Neuroscientist Explains How

Health & Fitness /

Dementia has no cure, and while some new drugs may slow its progression, they remain expensive and only marginally effective for many. However, a recent Cambridge-led study links commonly used prescription drugs—such as antibiotics, antivirals, and vaccines—to a lower risk of dementia. Since these drugs are already approved with well-known safety profiles, they could fast-track

Scientists Confirm: The Pandemic Had No Impact on the Moon

Space & Environment /

Can a pandemic change the Moon’s temperature? A 2024 study suggested global lockdowns reduced Earth’s heat radiation, cooling the Moon. But new research says otherwise. The original idea: As businesses shut down in 2020 and people stayed home, carbon emissions dropped, lowering terrestrial radiation—the heat Earth emits and the Moon absorbs. Scientists noted a dip
