Vita moln kan bli hotfullt mörka
Moln består av väldigt många små vattendroppar. För att moln ska kunna bildas krävs att de meteorologiska förutsättningarna vind, fuktighet och temperatur är de rätta. Det krävs också mycket små partiklar svävande i luften, som tjänar som embryon för molndropparna. I varje molndroppe finns en liten partikel på vilken droppen har bildats – en kondensationskärna. Dessa kan bestå av exempelvis luftfö

From the archive: what geese can teach us, 1966
Animal behaviour expert Konrad Lorenz explains why it is man who is red in tooth and claw You can see why the goslings on the cover of the Observer Magazine of 1 May 1966 took Konrad Lorenz ('the world authority on animal behaviour') to be their parent – with his feathery white hair he could pass for a goose himself. In fact, the geese have a 'fixed idea' that his hair is grass, which is why they

Oncotarget: Th1 cytokines potentiate apoptosis of breast cancer cells and suppress tumor growth
Volume 11, Issue 30 of Oncotarget reported that previously, the authors showed that anti-estrogen drugs combined with a dendritic cell-based anti-HER-2 vaccine known to induce strong Th1-polarized immunity dramatically improved clinical response rates in patients with HER-2pos/ERpos early breast cancer.

Elchocksexperiment: Nio av tio ökar styrkan i elstötarna när en auktoritet ber dem
Många av oss tror inte att vi skulle lyda order om att begå våld. Men i ett polskt experiment valde omkring 90 procent att ge vad de trodde var en annan medverkande allt starkare elstötar när en auktoritet bad dem. – Det är mycket sannolikt att vi alla skulle bete oss likadant, säger psykologen Tomasz Grzyb i Vetenskapens värld.

A controllable membrane to pull carbon dioxide out of exhaust streams
A system developed by chemical engineers could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.

Calcium bursts kill drug-resistant tumor cells
Multidrug resistance (MDR) — a process in which tumors become resistant to multiple medicines — is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that pump drugs out of the cell, rendering the chemotherapies ineffective. Now, researchers have developed nanoparticles that release bursts of calcium inside tumor cells, inhibi

Arctic Ocean sediments reveal permafrost thawing during past climate warming
Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings caution about what could happen in the near future: Arctic warming by only a few degrees Celsius may trigger massive permafrost thawing, coastal erosion, and the release

Extremists Don't Belong in the Military
