Fat Cells Seem to Cling to The Memory of Being Obese, Study Finds
Researchers from ETH Zurich found that mammalian fat cells retain a “memory” of past obesity through epigenetic changes, even after significant weight loss. Experiments on mice showed that formerly obese mice gained weight faster when fed a high-fat diet compared to control mice, suggesting their fat cells were “primed” for weight regain. The epigenetic changes […]
The People in Your Life Are Sharing Their Gut Microbes With You
Humans share gut microbes with the people they interact with face-to-face, including family, friends, and other social connections. This means your gut microbiome can serve as a “detailed profile of your social life.” A study led by researchers at Yale University analyzed the gut microbiomes of 1,787 adults living in isolated villages in Honduras and […]
China’s new drone submarine boasts 3452-mile underwater range, can carry torpedoes
China has unveiled a new large uncrewed diesel-electric drone submarine design. The submarine is reconfigurable to perform various missions like attacking ships, mine-laying, special operations support, and serving as a mothership for smaller underwater vehicles. The drone submarine model has a length ranging from around 124 feet to 141 feet, with a surface displacement between […]
Children With High IQs Get ADHD Diagnosed Later, Study Reveals
A new study found that children with higher IQs tend to get diagnosed with ADHD (attention-deficit hyperactivity disorder) at a later age compared to children with lower IQs. The study analyzed data from 568 young people aged 4-22 diagnosed with ADHD. Other factors like sex, socioeconomic status, and ethnicity were also examined. In addition to […]
New Thermal Material Could Slash Data Center Cooling Demands
Data center cooling is energy-intensive, accounting for about 40% of overall data center energy use (around 8 terawatt-hours per year). Researchers have developed a new organic thermal interface material (TIM) that can substantially improve heat dissipation from electronic components, reducing the demand on active cooling technologies like fans and liquid cooling. The new TIM is […]
Cannabis Really Can Induce Sleep, And Now We Know Why
Researchers from the University of Sydney have confirmed that the cannabis ingredient cannabinol (CBN) can increase sleep in rats. CBN is a breakdown product of the main psychoactive compound in cannabis, THC. The researchers found that CBN and its metabolites extended periods of both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep in […]
Study Finds Eggs Might Protect Brain Health And Lower Cholesterol
Researchers at the University of California San Diego analyzed data from 890 men and women and found that eating 2-4 eggs per week is linked to lower blood cholesterol levels. The analysis, based on a long-term healthy aging study, also showed that women who reported eating more eggs had less decline in short-term and long-term […]
Zombie Caterpillar Fungus Could Be Used to Save Human Lives
Researchers have found that a compound called cordycepin, produced by the parasitic Cordyceps and Ophiocordyceps fungi that infect and “zombify” caterpillars, can block pathways critical for the growth of some cancers. The researchers, from the University of Nottingham, built on previous research into the cancer-fighting capabilities of cordycepin. They used advanced scientific techniques to study […]
Here’s why robots are running marathons in China — it could be the future
Robots called Go2 and B2 became cheerleaders and pacesetters at the Hangzhou Marathon in China. Go2 played music, gave safety tips, and could perform backflips and handstands. B2 acted as a “pace-setting rabbit” to help runners maintain their pace. A humanoid robot called Tien Kung recently joined the Yizhuang Half Marathon in Beijing, running the […]
Deep-sea oarfish washes up on California beach ‘predicting doom’
A rare deep-sea oarfish was found washed up on a beach in Encinitas, California. This is the second time an oarfish has been found in the area this year. Oarfish sightings are very rare, with fewer than two dozen seen on the California coast in the past 120 years. They normally inhabit the deep ocean […]
