Organisms cope with environmental uncertainty by guessing the future

In uncertain environments, organisms use molecular processes to make guesses about the future, according to a study. Genetic identical individuals exhibit variation in stress responses due to random decisions, which is beneficial as it reduces metabolic costs without compromising overall benefits.

Earthworms soak up heavy metal

Researchers found that three earthworm species can remove up to 75% of heavy metals from waste, producing rich compost without accumulating toxins in crops. The worms' digestive system facilitates the separation of metal ions, allowing for safe disposal of organic waste.

New nanoparticles shrink tumors in mice

MIT researchers have developed RNA-delivering nanoparticles that allow for rapid screening of new drug targets in mice. These nanoparticles target the ID4 protein, shrinking ovarian tumors in their first mouse study. The technology has the potential to relieve a significant bottleneck in cancer-drug development.

Spiteful behavior is 'extreme', according to study

Research reveals that individuals who exhibit spiteful behavior are consistent in their actions over time, imposing maximum harm on others. The study, conducted by Erik Kimbrough and Philipp Reiss, used an artificial auction market scenario to test the frequency and extent of spiteful behavior among 48 student participants.

Good vibrations

Scientists at Berkeley Lab and UC Berkeley have made the first direct observations of distinctly quantum optical effects - amplification and squeezing - in an optomechanical system. The findings point toward low-power quantum optical devices and enhanced detection of gravitational waves.

Danger in the blood: U-M scientists show how antibiotic-resisting bacterial infections may form

Researchers demonstrate that bacteria can form antibiotic-resistant clumps in a short time, even in a flowing liquid such as the blood, leading to severe infections. These clumps persist even when two different types of antibiotics are added, suggesting that sticking together protects the floating bacteria from the drugs' effects.

By studying animal health, researchers find improved ways for developing, testing cancer therapies

Kansas State University researchers have made significant discoveries in cancer research by studying animal health. They found SCID pigs with severe combined immunodeficiency and discovered the connection between human cancer and pig diseases. This collaboration has huge potential for improving surgeries, drug development, and bone mar...

NIH study suggests potential hurdle to universal flu vaccine development may be overcome

Researchers found that a prime-boost vaccine regimen can elicit broadly neutralizing antibodies in animals with pre-existing immunity, offering hope for developing vaccines giving long-lasting flu protection. The study's results suggest that a universal flu vaccine may be possible, potentially benefiting people of all ages.

Be whoever you want to be!

Researchers from Ruhr-Universität Bochum discovered that 80 percent of Single Sign-On (SSO) systems based on SAML have huge vulnerabilities. The team used novel XML Signature Wrapping techniques to circumvent digital signatures, impersonating users and system administrators in 12 affected systems.

MASER power comes out of the cold

Researchers have developed a solid-state MASER capable of operating at room temperature, eliminating the need for extreme conditions. This breakthrough has significant implications for various fields, including medicine, where it could be used to create more sensitive medical instruments.

Continuous oral contraceptive pills offer women earlier pain relief

Researchers found that continuous oral contraceptive pills provide earlier relief for moderate to severe menstrual cramps, reducing symptoms by up to six months. Women taking the continuous treatment reported significant pain relief due to uninterrupted treatment, outperforming cyclic treatment in terms of pain relief timing.
