Cancer cells acquire genetic anomalies that allow them to grow and proliferate unchecked. Researchers have now found another difference between cancer cells and normal cells: the X chromosome, typically only inactivated in XX female cells, can be inact…

According to a new study that combined GPS, satellite data, and numerical modelling, ice loss from northeast Greenland could be six times greater by the end of the century than previously thought.

Researchers have created a tool that maps how breast cancer grows in previously unseen detail, and highlights how the cells around the tumor may be the key to controlling the spread of disease.

A new study finds that COVID-19 ‘Test to Treat’ sites — clinical centers launched based on a federal initiative to provide free testing, diagnosis, and immediate access to COVID-19 antiviral treatment with Paxlovid — may not be accessible to those wh…

Researchers have discovered that the neurotransmitter adenosine effectively acts as a brake to dopamine, another well-known neurotransmitter involved in motor control. The discovery could immediately suggest new avenues of drug development to treat sym…

Rejuvenating the immune cells that live in tissues surrounding the brain improves fluid flow and waste clearance from the brain — and may help treat or even prevent neurodegenerative diseases such as Alzheimer’s and Parkinson’s, according to a new stu…

A research group has made a material that can effectively separate heavy water from normal water at room temperature. Until now, this process has been very difficult and energy intensive. The findings have implications for industrial — and even biolog…

An international research team has measured the size of a star dating back more than 11 billion years ago using images that show the evolution of the star exploding and cooling. The research could help scientists learn more about the early Universe.

(Santa Barbara, Calif.) — Take a wire paperclip. Now, bend it back and forth in the same spot 15, maybe 20 times. Chances are the paperclip will have broken before you finish. This is due to what’s called metal fatigue, which occurs when a metal compo…

A study has found evidence that the evolution of tree roots over 300 million years ago triggered mass extinction events through the same chemical processes created by pollution in modern oceans and lakes.

Engineers have shown that medical devices made from aluminum can be disintegrated within the body by exposing them to gallium-indium, a liquid metal that seeps into the boundaries between the grains of the metal.

A new study illustrates how substrates affect electronic interactions in 2D metal-organic frameworks. With electronic properties tuneable by electrical charge, mechanical strain, and hybridization, such structures can be ‘switched’ off and on, allowing…

Researchers have released their first findings on the potential effectiveness of revolutionary gene drive technology to control invasive mice.

Scientists have successfully bioengineered an important protein in plants to increase the yield of oil from their fruits and seeds — a holy grail for the global agri-food industry. Their patent-pending method can increase oil content in seeds by 15 to…

Researchers have found a way to avoid the need to use radio transmitters in critical communications, using new technology featuring super-fast optical lasers.

How can we measure a skeleton’s motion in a furry animal as it moves through its environment? Researchers have developed a new method to quantify skeletal motion in freely moving rodents in a new level of accuracy and detail. It is based around buildin…

Almost one fourth of Sweden’s last unprotected old-growth forest was logged between 2003 and 2019. At this rate, all of these ecologically unique and valuable forests will be lost in about 50 years. These findings add to the growing body of evidence fo…

Molecular geneticists describe ways to develop the — as yet largely untapped — potential of RNA structures.

Countless tiny hairs (cilia) are found on the outer wall of some cells, for example in our lungs or in our brain. When these micrometer-sized hairs coordinate their movement and produce wave-like movements together, they can cause currents on a microsc…

Researchers have uncovered a cell-intrinsic mechanism, that controls the appropriate number of T cells in the organism and thus ensures that the immune system functions properly. This mechanism has also been found in slime molds, suggesting that this r…
