Mushroom Extract Demonstrates Potential in Fighting Prostate Cancer

Exotic mushrooms like Lion’s mane have garnered attention for their medicinal benefits, but common varieties, such as the white button mushroom, may also offer immune-boosting effects. The white button mushroom (Agaricus bisporus) is the world’s most cultivated edible mushroom. Although not typically seen as medicinal, emerging studies suggest its extract may help slow or even […]

New Ultrasound-Controlled Gene Therapy to Fight Cancer

Healthcare, Medicine / Samilton Santos

Researchers have developed an innovative gene therapy for cancer that can be remotely activated in specific areas of the body. The approach uses a version of CRISPR that responds to ultrasound pulses and has demonstrated effectiveness in eliminating tumors in mice. CRISPR is a powerful gene-editing tool that employs the Cas9 enzyme to make precise

Dolphins in Gulf Found Contaminated with Fentanyl

Biology, Science / Samilton Santos

Recent research has detected fentanyl and other drugs in dozens of dolphins in the Gulf of Mexico, just months after cocaine was found in sharks off the coast of South America. This finding highlights the growing problem of pharmaceuticals infiltrating marine environments. “Pharmaceuticals have emerged as micropollutants and are becoming a global concern, with their

These Temporary Electronic Tattoos Can Monitor Brain Activity

Healthcare, Medicine, Science / Samilton Santos

Traditional non-invasive brain imaging methods involve electrodes, sticky gels, and wires, which can be uncomfortable, unsightly, and time-consuming. However, scientists have recently developed a promising alternative in the form of temporary electronic tattoos. E-Tattoos: A More Comfortable and Accurate Alternative These e-tattoos use liquid ink applied to the scalp. In a recent study, they proved

NASA’s Moon Return Missions Face Further Delays

Astronomy, Astrophysics, Planetary Science / Samilton Santos

The Artemis II and III missions, which aim to return U.S. astronauts to the Moon, have been delayed once again. At a press briefing, NASA officials revealed that issues with the heat shield and life support systems would push back the launches to 2026 and 2027. On December 5, NASA Administrator Bill Nelson, Deputy Administrator

Ancient Black Holes Could Leave Tiny Tunnels in Rocks and Buildings

Astronomy, Astrophysics / Samilton Santos

Black holes are usually detected light-years away, but a new study suggests they could also be found here on Earth, in the form of tiny tunnels carved through rocks or ancient buildings. Scientists theorize that primordial black holes formed shortly after the Big Bang, unlike regular black holes, which form from collapsing massive stars. They

Fish Can Choose Their Own Birth Timing—Here’s How

Biology, Science / Mauro Lucas

Fish embryos in many species can control their hatching timing, effectively selecting their own birthdays. A study from Hebrew University of Jerusalem has uncovered the chemical and biological processes enabling this precise control, showing how embryos align their hatching with optimal environmental conditions. Researchers focused on zebrafish (Danio rerio) and discovered that the thyrotropin-releasing hormone

Research Reveals That Sleep Can Improve Decision-Making

Healthcare / Jorge Paka

Author John Steinbeck once remarked, “It is a common experience that a problem difficult at night is resolved in the morning after the committee of sleep has worked on it.” Countless individuals have credited their dreams with inspiring breakthroughs and innovations. Modern research into the science of sleep now provides evidence that supports these assertions.

Innovative tech harnesses cyborg mollusks to detect water pollution.

Earth Science, Environmental Science / Mauro Lucas

Scientists have developed a commercial water-quality monitoring system, molluSCAN-eye, which uses live, electronically enhanced mollusks to detect pollution. Filter-feeding mollusks like oysters and mussels naturally respond to pollutants by altering how they open their shells, making them ideal sensors. Each molluSCAN-eye unit houses 16 mollusks in a cage submerged at monitoring sites such as ports,

Watch: Biomimetic Robo-Bird Takes Flight with a Leap

Robotics, Science / Mauro Lucas

While autonomous flying robots hold promising potential, their usefulness is limited if they cannot navigate uneven terrain after landing. However, an experimental bio-inspired robot overcomes this limitation by mimicking the raven’s gait. Named RAVEN (Robotic Avian-inspired Vehicle for Multiple Environments), the device was developed by Won Dong Shin and his team at Switzerland’s EPFL university.
