Hunter-gatherers have a special way with smells

When it comes to naming colors, most people do so with ease. But, for odors, it's much harder to find the words. One notable exception to this rule is found among the Jahai people, a group of hunter-gatherers living in the Malay Peninsula. Show More Summary

New method to stop cells dividing could help fight cancer

Researchers at Uppsala University, Karolinska Institutet, and the University of Oxford, have used a new strategy to shut down specific enzymes to stop cells from dividing. The method, published in Cell Chemical Biology, can be used as a strategy to fight cancer.

Gene edited crops should be exempted from GM food laws, says EU lawyer

Technology can help foster specific positive traits in plants but can also have potentially dangerous ‘off-target’ effects, say critics Gene editing technologies should be largely exempted from EU laws on GM food, although individual...Show More Summary

New technique for finding life on Mars

(Frontiers) Miniaturized scientific instruments and new microbiology techniques successfully identified and characterized microorganisms living in Arctic permafrost -- one of the closest analogs to Mars on Earth. By avoiding delays that...Show More Summary

From healthcare to warfare: How to regulate brain technology

(University of Basel) Ethicists from the University of Basel have outlined a new biosecurity framework specific to neurotechnology. While the researchers declare an outright ban of dual-use technology ethically unjustified, they call for regulations aimed at protecting the mental privacy and integrity of humans. The journal Neuron has published the study.

0.6% soy isoflavone in the diet decrease muscle atrophy

(Tokyo Institute of Technology) Scientists at Tokyo Institute of Technology (Tokyo Tech) have discovered a means of reducing muscle atrophy by the addition of the soy-derived isoflavone aglycone (AglyMax) to the diet of mice. This attenuation by soy isoflavone is attributable to block the apoptosis-dependent pathway in muscle fiber. Show More Summary

Efficacy of antibody targeting Devic's disease proven in new animal model

(Osaka University) Neuromyelitis optica (NMO) is an autoimmune disease associated with NMO immunoglobulin G (NMO-IgG). A cure for NMO remains elusive. Osaka University researchers recently established a localized NMO rat model by injecting...Show More Summary

Genomics reveals key macrophages' involvement in systemic sclerosis

(Duke-NUS Medical School) A new international study has made an important discovery about the key role of macrophages, a type of immune cell, in systemic sclerosis (SSc), a chronic autoimmune disease which currently has no cure.

New instrument lets doctors view the entire eye with unprecedented level of detail

(The Optical Society) Researchers have developed the first instrument that can provide a detailed image of the entire eye that can produce higher quality images than currently available.

Warming Arctic climate constrains life in cold-adapted mammals

Despite the growth in knowledge about the effects of a warming Arctic on its cold-adapted species, how these changes affect animal populations is poorly understood. Research efforts have been hindered by the area's remoteness and complex logistics required to gain access.

Hybridization can give rise to different genome combinations

Researchers have for the first time determined that hybridization between two bird species can give rise to several novel and fully functional hybrid genomic combinations. This could potentially be because hybrid species emerged through independent hybridisation events between the same parent species on different islands.

Have scientists really found the germ responsible for killing 15m Aztecs?

This week, dozens of media outlets declared that scientists had solved the mystery of what wiped out the Aztecs. Traces of a pathogen that can cause a typhoid-like enteric fever have been found in skeletons from a cemetery linked to the catastrophic epidemics of 1545-50, which killed millions of indigenous people in 16th century Mexico.

How did we evolve to live longer?

Research shows a collection of small adaptations in stress activated proteins, accumulated over millennia of human history, could help to explain our increased natural defences and longer lifespan.

Mealworms may turn infected wheat into cash

The potential solution discovered by University of Saskatchewan researchers for producers stuck with unsellable fusarium-infected wheat may actually put cash in the farmers' pockets and open up a new worm-based niche market in the feed industry.

Seasonal variability of the carbonate system and coccolithophore Emiliania huxleyi at a Scottish Coastal Observatory monitoring site

Highlights • There is a “knowledge gap” on carbonate chemistry in inshore waters. • Stonehaven coastal carbonate system shows a strong variability at short-time and year-to-year scales. • Occurrence of E. huxleyi morphotypes shows a repeated seasonal pattern. • E. huxleyi in situ calcification seems not to be affected by carbonate chemistry. • Seasonality in […]

New research finds drinking 100% fruit juice does not affect blood sugar levels

(Kellen Communications - NY) New research demonstrates that 100% fruit juice has no impact on blood sugar levels.

A survival lesson from bats—eating variety keeps species multiplying

Diet is an important factor influencing the survival and evolution of all species. Many studies have shown that when species evolve from being a predator or insectivore to being a vegetarian, the rate at which new species arise increases. Show More Summary

Hanging with the locals pays off for tropical invaders

Studying the behaviour of tropical fish in a temperate environment can help predict who might be winners and losers in a warmer future, and how resources such as fish stocks may be impacted, researchers say.

The Y chromosome is disappearing – so what will happen to men?

The Y chromosome may be a symbol of masculinity, but it is becoming increasingly clear that it is anything but strong and enduring. Although it carries the "master switch" gene, SRY, that determines whether an embryo will develop as male (XY) or female (XX), it contains very few other genes and is the only chromosome not necessary for life.

The rise of turfs—flattening of global kelp forests

Research published today into the state of kelp forests around the world shows they are being degraded into flat seascapes carpeted by short, unwanted turf-algae – and the Western Australian coastline is one of the worst-affected ar...
