"Take with food" is a common warning for people using antibiotics, but a discovery announced this week in the scientific journal Nature may create a path to more targeted drugs.
This advice for taking antibiotics is needed because current drugs kill any...
Do potassium ions pass through the selectivity filter of a potassium channel alone, or are there water molecules between the ions, too? This question has been a source of controversy for years. Researchers led by Prof. Adam Lange from...
A genetic mutation that slowed down the development of the prefrontal cortex (PFC) in two or more children may have triggered a cascade of events leading to acquisition of recursive language and modern imagination 70,000 years ago.
This new hypothesis,...
For the first time, scientists have unraveled genetic changes that cause rapid fish evolution due to intense harvesting—changes that previously had been invisible to researchers.
Over recent decades, many commercially harvested fish have grown slower and matured earlier, which can translate into lower...
In certain turtle species, the temperature of the egg determines whether the offspring is female or male. But now, new research shows that the embryos have some say in their own sexual destiny: they can move around inside the...
The artificial cells could be used to sense changes in the body and respond by releasing drug molecules, or to sense and remove harmful metals in the environment.
Responding to chemical changes is a crucial function of biological cells. For example, cells...
Old-school Hollywood editors cut unwanted frames of film and patched in desired frames to make a movie. The human body does something similar—trillions of times per second—through a biochemical editing process called RNA splicing. Rather than cutting film, it...
To the heroes among you who eat the whole apple: besides extra fiber, flavonoids and flavor, you're also quaffing 10 times as many bacteria per fruit as your core-discarding counterparts.
Is this a good thing? Probably. But it might depend...
Knowing which direction to go in order to reach food or home is important for many animal species, including humans. For human foragers who travel long distances every day for hunting and gathering, orientation skills are essential. Haneul Jang...
Scientists have given a fascinating new insight into the way microbes adopt a 'co-operative' approach to securing the nutrients they need to thrive.
A team of bioscientists from the University of Exeter have investigated why microorganisms spurn a "survival of...
In the time it takes you to read this sentence, every cell in your body suffers some form of DNA damage. Without vigilant repair, cancer would run rampant, and now scientists at the University of Pittsburgh have gotten a...
