Super-Typhoon Haiyan lashes the Philippines

<span style=”line-height: 14.545454025268555px; font-size: 8pt; font-family: Georgia, serif;”>Super-Typhoon Haiyan was lashing the central and southern philippines on Nov. 7 bringing maximum sustained winds of a Category 5 hurricane. The U.S. National Hurricane Center website indicates that a Category 5 hurricane/typhoon would cause catastrophic damage: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

‘Tiger stripes’ underneath Antarctic glaciers slow the flow

<span style=”line-height: 14.545454025268555px; font-size: 8pt; font-family: Georgia, serif;”>Researchers have discovered that most resistance to the movement of glaciers over the underlying bedrock comes from narrow, high-friction stripes that lie within large, extremely slippery areas underneath the glacier. These stripes are thought to govern the speed at which Antarctic glaciers are moving.

<span style=”line-height: 14.545454025268555px; font-size: 8pt; font-family: Georgia, serif;”>Basic ocean conditions such as current directions and water temperature play a huge role in determining the behavior of young migrating salmon as they move from rivers and hit ocean waters for the first time, according to new research. How the fish fare during their first few weeks in the ocean has a profound impact on species’ ability to survive into adulthood.

Edited RNA plus invasive DNA add individuality

<span style=”line-height: 14.545454025268555px; font-size: 8pt; font-family: Georgia, serif;”>An enzyme that edits rna may loosen the genome’s control over invasive snippets of dna that affect how genes are expressed, according to new research. In fruit flies, that newly understood mechanism appears to contribute to differences among individuals such as eye color and life span.

Origins of cattle farming in China uncovered

<span style=”line-height: 14.545454025268555px; font-size: 8pt; font-family: Georgia, serif;”>Scientists have produced the first multi-disciplinary evidence for management of cattle populations in northern China, around the same time cattle domestication took place in the Near East, over 10,000 years ago.

Unique change in protein structure guides production of RNA from DNA

<span style=”line-height: 14.545454025268555px; font-size: 8pt; font-family: Georgia, serif;”>One of biology’s most fundamental processes is transcription. It is just one step of many required to build proteins — and without it life would not exist. However, many aspects of transcription remain shrouded in mystery. But now, scientists are shedding light on key aspects of transcription, and in so doing are coming even closer to understanding the importance of this process in the growth and development of cells — as well as what happens when this process goes awry.
