ACS Spring 2021 press conference schedule

New methods to detect doping compounds in urine samples using ion mobility-mass spectrometry will help regulatory agencies track existing dopants and future 'designer' compounds. Baltic amber's therapeutic effects have been pinpointed, potentially leading to new medicines for antibiotic-resistant infections. Scientists also report a wa...

Researchers develop microscopic theory of polymer gel

Researchers have proposed a new microscopic theory of polymer gel collapse, shedding light on the dramatic reduction in volume of zwitterionic hydrogels when cooled. The theory explains the role of electrostatic interactions between polymer units in leading to gel collapse, and identifies key parameters that influence this transition.

New nanoscale device for spin technology

Researchers at Aalto University developed a new device for spintronics, allowing control and filtering of spin waves in devices as small as hundreds of nanometres. The device uses exotic magnetic materials to trap and cancel out unwanted frequencies, enabling faster processing and wireless transmission.

The fate of the planet

Experts warn of potential global catastrophes such as engineered pandemics and nuclear annihilation, while also identifying areas for improvement. Scientists like Martin Rees argue that promoting wise technology deployment can minimize risks and ensure a sustainable future.

Vitamin D deficiency may impair muscle function

A mouse study found that vitamin D deficiency impairs skeletal muscle mitochondrial function, leading to reduced energy production and potentially poor muscle strength. The study suggests that preventing vitamin D deficiency in older adults could help maintain better muscle function and reduce age-related muscle deterioration.

Triangular-shaped spikes key to coronavirus transmission, finds new study

A recent study published in Physics of Fluids reveals that the triangular shape of coronavirus spikes plays a crucial role in its ability to spread. The research, conducted by scientists at OIST and Queen's University, found that the spikes' lower rotational diffusivity enables the virus to better attach itself to objects and people.

Egg and sperm cell size evolved from competition

Researchers found that competition for resources led to the development of vastly different sizes between egg cells and sperm cells. The study used mathematical modeling to demonstrate how natural selection favored larger gametes due to increased nutritional value, while smaller gametes required fewer resources.

Leonardo da Vinci definitely did not sculpt the Flora bust

A team of scientists from CNRS has proven that Leonardo da Vinci did not sculpt the Flora wax bust, which was conserved at the Bode Museum in Berlin. The radiocarbon dating revealed that the sculpture was made in the 19th century, nearly 300 years after da Vinci's death.

A new treatment for rare muscular disease

Researchers at the University of Cincinnati have developed a new treatment for Pompe disease, a genetic condition that affects 1 in 40,000 people in the US. The treatment has been shown to be safer and more effective than current therapy, improving respiratory muscle function, endurance, and overall quality of life.

Research sheds new light on pancreatic cancer metastasis

A recent study published in Gastroenterology reveals that overexpression of the ZIP4 protein in patients with pancreatic cancer enables tumor cells to transform into a shape-shifting form, evading detection and metastasizing to other organs. Understanding this process is crucial for developing targeted therapies to stop metastasis.

The future of particle accelerators is here

The Electron Ion Collider will take 3D images of electrons colliding with polarized protons and ions, shedding light on fundamental questions in nuclear physics. The collider's experimental equipment may also detect the elusive chiral magnetic effect, a crucial prediction for understanding the universe's matter-antimatter imbalance.

Fit matters most when double masking to protect yourself from COVID-19

A study published in JAMA Internal Medicine shows that wearing two face coverings can significantly improve filtration efficiency, especially when properly fitted. Researchers found that cloth masks placed over surgical masks or vice versa can improve fit and effectiveness, but loosely fitting masks do not provide the same benefit.
