Humans have them, so do other animals and plants â now research reveals that non-photosynthetic bacteria too have internal daily clocks that align with the 24-hour cycle of life on Earth.
The research answers a long-standing biological question and could have implications for the timing of drug delivery, biotechnology, and how we develop timely solutions for crop protection.
Biological clocks or circadian rhythms are exquisite internal timing mechanisms that are widespread across nature enabling living organisms to cope with the major changes that occur from day to night, even across seasons.

Galaxies begin to die when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away galaxy. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have seen a galaxy ejecting nearly half of its star-forming gas. This ejection is happening at a startling rate, equivalent to 10 000 Suns-worth of gas a year the galaxy is rapidly losing its fuel to make new stars. The team believes that this spectacular event was triggered by a collision with another galaxy, which could lead astronomers to rethink how galaxies stop bringing new stars to life.

How does home working change managerial duties?
Associate Professor Christine Ipsen was among the first to study the reactions to the increased home working during the corona crisis. Here she answers some questions about challenges and possibilities for distance management.
What characterizes distance management?
An obvious characteristic feature is the distance between manager and employee. The distance may be both geographical and temporal, i.e. working at different times of the day or in different time zones. Distance management is already being used in many industries, for example in the transport sector, in home care, and in international companies with departments and branches worldwide, where employees and managers may be located in different countries. The new aspect under the COVID-19 crisis is that suddenly many more managers had to become distance managers, even thought this was not the managerial task they were used to.

Research headed by scientists at the Ludwig Maximilians University (LMU), Munich, has shown that just like humans and other organisms bacteria have internal clocks that align with the 24-hour day-night cycle. “We’ve found for the first time that nonphotosynthetic bacteria can tell the time,” said LMU research lead Martha Merrow, PhD. “They adapt their molecular workings to the time of day by reading the cycles in the light or in the temperature environment.”

Intelligent alarm system helps Covid-19 patients
A group of Danish researchers from DTU Health Tech in collaboration with Rigshospitalet, Bispebjerg and Frederiksberg Hospital have developed a unique patient surveillance system with wireless monitoring. The system will now be distributed to all Danish hospitals.
An artificial intelligent system with wireless 24/7 monitoring of patients will make it easier for the country’s hospitals to keep an eye on whether the condition of patients with covid-19 is suddenly deteriorating. Initially, Rigshospitalet, Bispebjerg and Frederiksberg Hospital will start using the system. But the Danish Regions have granted resources for up to 250 units to relieve the pressure on hospital staff and secure the best possible patient care in the hospital wards across the country.
