Real-Time Kinetics of Internalization of Anti-EGFR DNA Aptamers and Aptamer Constructs into Cells Derived from Glioblastoma Patients as Indicated by Doxorubicin Open
The WHO considers the Epidermal Growth Factor Receptor (EGFR) one of the key biomarkers of glioblastoma (GB). EGFR can be identified and targeted using molecular recognition elements (MoREs), like aptamers and aptamer–drug conjugates (ApDC…

Tectonic framework of the Podrumche-Dazhdovnik basin, Eastern Rhodopes: implications for gold exploration in the region Open
Based on recent surface mapping and drill core data, we propose a new outlook on the tectonic framework of the Eocene–Oligocene Podrumche-Dazhdovnik basin in the Bulgarian Eastern Rhodopes. The present-day basin geometry and architecture i…

Impact Craters on Earth with a Diameter of More than 200 km: Numerical Modeling Open
The three largest impact craters, the remains of which have been found on Earth to date, had diameters of about 200 km immediately after formation. The search for traces of larger impact structures continues. This paper presents the result…

Ina summit pit-crater: Geology and stratigraphy of a young impact crater and implications for unit substrate characteristics, emplacement sequence and age. Open
Introduction: Irregular Mare Patches (IMPs) [1] have a rough floor unit (FU) and meniscus-like mounds (MD). Initial Ina CSFD measurements produced ages of ~59 Ma; but Ina is closely associated with an ~3.5 Ga edifice [2]. Could IMP mounds …

Antiferromagnetic droplet soliton driven by spin current Open
We demonstrate that a spin current flowing through a nano-contact into a uniaxial antiferromagnet with first- and second-order anisotropy can excite a self-localized dynamic magnetic soliton, known as a spin-wave droplet in ferromagnets. T…

Empowering Control of Antiferromagnets by THz-induced Spin Coherence Open
Finding efficient and ultrafast ways to control antiferromagnets is believed to be instrumental in unlocking their potential for magnetic devices operating at THz frequencies. Still, it is challenged by the absence of net magnetization in …

Spin Hall Nano-Oscillator Based on an Antiferromagnetic Domain Wall Open
We propose here a high-frequency spin-Hall nano-oscillator based on a simple magnetic texture, such as a domain wall, located in an antiferromagnet with easy-axis anisotropy type. We show that the spin current, polarized along the anisotro…

Controlling magnetism with light in a zero orbital angular momentum antiferromagnet Open
Antiferromagnetic materials feature intrinsic ultrafast spin dynamics, making them ideal candidates for future magnonic devices operating at THz frequencies. A major focus of current research is the investigation of optical methods for the…

Impact features on Venus: Modeling craters and splotches Open
<p>Our team has discovered first impact craters under the thick Venusian atmosphere with radar images during the Venera 15/16 mission. Later Magellan radar images of a better quality allowed us to count all impact craters and to find…

Mars surface dust activation at small meteoroid’s impacts Open
<p>We continue the analysis of HiRISE high resolution images of Mars to understand properties of dust covering the surface. The data on dust devils observed with Mars landers and surface traces of dust devils could be expanded with e…

The observed recent surface air temperature development across Svalbard and concurring footprints in local sea ice cover Open
<p>The Svalbard archipelago in the Arctic North Atlantic is experiencing rapid changes in the surface climate and sea ice distribution, with impacts for the coupled climate system and the local society. Using observational data of su…

New craters on Mars: Air shock wave traces Open
<p>The idea of visualizing shock wave passage along a dusty (sooty) surface was first proposed and tested by Ernst Mach. High resolution HiRISE images of new impact craters on dusty areas of Mars gave in many cases revealed dark &…

Asteroid impact effects on Snowball Earth Open
Several Snowball Earth periods, in which the Earth has been (almost) totally glaciated, are known from Earth history. Neither the trigger for the initiation, nor the reason for the ending of such phases, are well understood. Here we discus…

Double and multiple craters on the satellites of Saturn and Jupiter and their implications on impactor size distributions Open
Crater doublets and multiple craters can be created by the break-up of impactors prior to impacting a planetary surface. In this study we use crater scaling laws to constrain the original size of an impactor prior to its disintegration int…

Slow Impacts on Strong Targets Bring on the Heat Open
An important new paper by Kurosawa and Genda (2017, https://doi.org/10.1002/2017GL076285 ) reports a previously overlooked source of heating in low velocity meteorite impacts. Plastic deformation of the pressure‐strengthened rocks behind t…
