Experts recommend against diagnosing testosterone deficiency in women

The Endocrine Society today issued a Clinical Practice Guideline (CPG) advising against the use of testosterone therapy in healthy women.Androgens are a group of sex hormones that includes testosterone. DHEA is a prohormone that can be converted into testosterone or estradiol, a form of estrogen. While these are often thought of as male hormones, small amounts of androgens also are found in women.

World Falling Short of Biodiversity Goals for 2020

A mid-term assessment of the 20 biodiversity-related “Aichi Targets,” which were agreed upon by 150 nations at the Convention on Biological Diversity in 2010, reveals that although the global community has made some progress, these goals are unlikely to be met by 2020.

Satellite Data Reveal Wealth of Hidden Tectonic Structures

Using the latest data from satellites in space, scientists have uncovered uncharted features in the seafloor, 80% of which remains unmapped. The rifts, ridges and trenches of the ocean floor are shaped by the slipping and sliding of massive tectonic plates. In many parts of the ocean, however, including the region of the Indian Ocean where the Malaysian aircraft was lost this year, scientists don't know much about seafloor tectonics.

Cheetahs and Pumas Strike a Balance to Hunt

Being a carnivore -- stalking, chasing and killing your prey -- is hard work. But two new studies show that cheetahs and pumas have their hunts down to a science. The studies suggest that mid-size predators, or mesopredators, may not be as energetically constrained by resources and competition as researchers had imagined. However, they also imply that human activity could offset the delicate balance these mesopredators have struck over thousands of years of evolution.

Uncovering the Hidden History of AIDS’ Spread

To help shed light on AIDS’ early history, Nuno Faria et al. analyzed HIV-1 group M sequences from a major HIV sequence database; by combining these analyses with spatial and epidemiological data, they were able to show that the HIV-1 group M pandemic originated in Kinshasa, now the capital of the Democratic Republic of Congo, in the early 1920s.

High Blood Sugar May Worsen Spinal Cord Injury

Scientists have discovered yet another reason to curb sugar consumption: high levels of it in the blood may make recovery after spinal cord injury harder. Controlling blood sugar levels in patients with spinal cord injury could potentially help doctors prevent additional neurological deterioration.

Laser-Guided Herds of Sea Monkeys Show how Zooplankton Migrations May Affect Global Ocean Currents

Two researchers at the California Institute of Technology have shown experimentally that this pattern creates water currents much larger than the sum of those created by individual organisms in the group. Their results, published in the journal Physics of Fluids, from AIP Publishing, suggest that the collective movement of small marine organisms could affect global ocean circulation patterns on a level comparable to the wind and the tides.

New estimates on carbon emissions triggered by 300 years of cropland expansion in Northeast China

The land use activities caused large carbon emissions since the industrial revolution. This quantitative carbon emission evaluation of the cultivation in Northeast China during the past 300 years indicated that the forest and grassland were the main carbon sources, and the soil lost more carbon than the vegetation. This study has been published on SCIENCE CHINA Earth Sciences(In Chinese), 2014, No.9.

Climate and canoe voyaging during South Pacific migrations

A pair of studies investigates canoe-building technologies and likely climate conditions that allowed early Polynesians to colonize areas such as New Zealand and Easter Island. Archaeological evidence suggests a rapid colonization of Polynesian islands, including New Zealand, around 1300 AD.

Bark beetle outbreaks and Rocky Mountain forest fires

Mountain pine beetle infestation in Rocky Mountain subalpine forests may not necessarily be related to subsequent forest fire severity, according to a study. Mortality of lodgepole pine trees due to bark beetle infestation has raised concerns that beetle-killed trees may lead to more severe fires in the western United States.

Liquid phase 3D printing method with low melting point alloy ink was invented

A latest study proposed and demonstrated a liquid-phase 3D printing for quickly manufacturing conductive metal objects. Through introducing a four-element alloy Bi35In48.6Sn16Zn0.4 whose melting point is slightly above room temperature as the printing ink, a series of typical structures were fabricated in the cooling liquid via a convenient way. This study has been published on SCIENCE CHINA Technological Sciences, 2014, Vol 57(9).

Smithsonian scientists discover coral's best defender against an army of sea stars

Coral reefs face a suite of perilous threats in today's ocean. From overfishing and pollution to coastal development and climate change, fragile coral ecosystems are disappearing at unprecedented rates around the world. Despite this trend, some species of corals surrounding the island of Moorea in French Polynesia have a natural protector in their tropical environment: coral guard-crabs.

Human trafficking, an invisible problem

Human trafficking is a problem about which little is known in Spain, due to both the lack of reliable figures as well as the poor coordination among international police forces and the social permissiveness with regard to certain behavior related to the sex trade. These are some of the conclusions of a report funded by the European Union and written by a research team in which experts from Universidad Carlos III de Madrid (UC3M) participated.

Is it still necessary to pursue super high yields in rice production?

Super high rice yields require high inputs, which reduces profit, increases crop risk, and has environmental consequences. To achieve food security in China, new rice cropping systems that increase multi-cropping index and harvest frequency have to be developed. Such new cropping systems require mechanization and simplification of crop management practices and new rice varieties. This article has been published on SCIENCE CHINA Life Sciences(In Chinese), 2014, No.8.

How epigenetic effects direct blood cells in the immune system

Three new studies shed light on how epigenetic effects -- which may affect whether a gene or protein is expressed -- direct blood cells to develop into the many components of the immune system. The studies were undertaken by scientists from the European Union’s BLUEPRINT project, which aims to further researchers’ understanding of how epigenetic effects influence both healthy and diseased human cells.
