A dust-up: Microbes interact with harmful chemicals in dust

Microbes in household dust can break down harmful chemicals

15-Apr-2019

The dust that settles throughout our homes and offices almost always contains bits of chemicals that can cause problems for the human endocrine system, scientists say. But a new study indicates that the microbes we track into buildings--the microscopic bacteria and other microorganisms that ...

A long-distance relationship in femtoseconds

Physicists observe how electron-hole pairs drift apart at ultrafast speed, but still remain strongly bound

15-Apr-2019

Modern electronics relies on ultrafast charge motion on ever shorter length scales. Physicists from Regensburg and Gothenburg have now succeeded in resolving a key quantum motion of electrons in atomically thin crystals on the time scale of a single oscillation cycle of light. They directly ...

Targeted approach to therapy for rare type of bone cancer

12-Apr-2019

Chordomas are rare bone tumors for which only few options of treatment exist. Scientists and doctors from the National Center for Tumor Diseases (NCT) Heidelberg, the German Cancer Research Center (DKFZ), and Heidelberg University Hospital (UKHD) have discovered a particular genetic trait of ...

Ultrasound aligns living cells in bioprinted tissues

12-Apr-2019

North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process. "We've reached the point where we are able to create medical products, such as knee implants, by ...

Water that never freezes

12-Apr-2019

Can water reach minus 263 degrees Celsius without turning into ice? Yes it can, say researchers from ETH Zurich and the University of Zurich, if it is confined in nanometre-scale lipid channels. Making ice cubes is a simple process: you take a plastic ice-cube tray like you’d find in most ...

A molecular switch for the X chromosome

Elucidation of basic mechanism to initiate the inactivation of X chromosomes in female organisms

10-Apr-2019

A large number of genes have to be switched on or off at different times during development. A particular challenge occurs when two copies of the same gene must acquire opposing states of activation within the same cell, as it is the case, for example, for the two X chromosomes in the female ...

New biologically derived metal-organic framework mimics DNA

10-Apr-2019

The field of materials science has become abuzz with "metal-organic frameworks" (MOFs), versatile compounds made up of metal ions connected to organic ligands, thus forming one-, two-, or three-dimensional structures. There is now an ever-growing list of applications for MOF, including separating ...

Instilling order and knowledge into the flood of data

09-Apr-2019

In the context of a project funded by the Austrian Science Fund FWF, a research group from the St. Pölten University of Applied Sciences has developed a versatile framework for data visualisation that permits easy integration of expert knowledge. Processing large amounts of data is one of the ...

Black nanoparticles slow the growth of tumors

Melanin as a new diagnosis and treatment tool for tumors

08-Apr-2019

The dark skin pigment melanin protects us from the sun’s damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment, as demonstrated by a team from the Technical University of Munich (TUM) and Helmholtz Zentrum ...

A peptide against cannibalism

A small molecule safeguards roundworm larvae against parental attacks

08-Apr-2019

A worm whose favorite dish is – of all things - worm larvae has to take great care not to accidentally devour its own progeny. How these tiny worms of merely a millimeter in length manage to distinguish their own offspring from that of other worms and avoid cannibalism has recently been ...
