Phys.org / Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked ...

Medical Xpress / Cancer also knows how to wait: Study uncovers the hidden step between mutation and tumor biomass appearance

The development of cancer is not a process triggered immediately by the emergence of an oncogenic mutation. There is growing evidence for the existence of an intermediate phase—hitherto poorly defined—in which mutated cells ...

Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn

Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...

Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork

Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...

Phys.org / How to stop a mouse plague

The scenes are biblical. Tens of thousands of rodents scattering across canola fields, behind sheds, into machinery. River fish with bellies full of mice. Carcasses littering the street, the sidewalk, outside your home. In ...

Phys.org / Hantaviruses may have co-evolved with rodents for ages, helping explain silent spread

What does a hantavirus do inside its rodent hosts? How do these viruses move through animal populations? And how is it that they cause almost no apparent symptoms in rodents, yet can be nearly fatal in humans? Specially Appointed ...

Phys.org / Diffractive networks enable optical information transfer through random and unknown diffusers

The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, telecommunications and remote sensing. When light passes through a turbid or diffusive medium, such ...

Phys.org / Harsh UVB bursts leave tadpoles with more DNA damage than longer exposure

Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. ...

Phys.org / Orbitronics clears key hurdle with direct orbital currents, boosting signals 100-fold

Researchers at Johannes Gutenberg University Mainz (JGU) are the first to directly utilize orbital currents without the need for conversion of the orbital current into a spin current.

Medical Xpress / Two prostate cancer mutations reveal opposite responses to ferroptosis therapy

A new study by researchers at The University of Texas MD Anderson Cancer Center has identified genetic factors that determine whether prostate cancers are susceptible to a type of cell death known as ferroptosis. These findings, ...

Phys.org / How winter conditions shape future jellyfish blooms

Marine scientists at the University of Chester have discovered that environmental conditions experienced by jellyfish before winter can have lasting effects on the size and intensity of jellyfish blooms many months later. ...
