Research: Enzyme that protects against viruses could fuel cancer evolution
Updated : 3 years, 3 months ago IST
An enzyme that defends human cells against viruses can help drive cancer evolution towards greater malignancy by causing myriad mutations in cancer cells, according to a study led by investigators at Weill Cornell Medicine. The finding suggests that the enzyme may be a potential target for f

Textbooks not keeping pace of increasing climate impacts: Research
Updated : 3 years, 3 months ago IST
A new study from North Carolina State University finds that biology textbooks have done a poor job of incorporating material related to climate change. For example, the study found that most textbooks published in the 2010s included less information about climate change than they did in the

Microplastics deposited on seafloor triple in 20 years: Research
Updated : 3 years, 3 months ago IST
The total amount of microplastics deposited at the bottom of oceans has tripled in the past two decades with a progression that corresponds to the type and volume of consumption of plastic products by society.

Scientists unlock cancer's ancestry
Updated : 3 years, 3 months ago IST
Could knowing where your ancestors came from be the key to better cancer treatments? Maybe, but where would that key fit? How can we trace cancer's ancestral roots to modern-day solutions? For Cold Spring Harbor Laboratory (CSHL) Research Professor Alexander Krasnitz, the answers may lie dee

Current Antarctic conservation efforts insufficient to avoid biodiversity
Updated : 3 years, 3 months ago IST
Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65 per cent of the continent's plants and wildlife by the year 2100, according to a study

Massive 'marimo' algae balls at risk from deadly winter sunburn
Updated : 3 years, 3 months ago IST
Climate change could overexpose rare underwater "marimo" algae balls to sunlight, killing them off according to a new study at the University of Tokyo. Marimo are living fluffy balls of green algae. The world's largest marimo can be found in Lake Akan in Hokkaido, Japan's northern main isla

Study identifies new cause for melting Antarctic ice shelves
Updated : 3 years, 3 months ago IST
Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic. An international team of scientists found that adjacent ice shelves play a role in causing instability in others downstream.

Diving birds more prone to extinction: Scientists
Updated : 3 years, 3 months ago IST
Diving birds like penguins, puffins and cormorants may be more prone to extinction than non-diving birds, according to a new study by the Milner Centre for Evolution at the University of Bath. The authors suggest this is because they are highly specialised and therefore less able to adapt to

Scientists study 155 new genes to see how humans continue to evolve
Updated : 2 years, 5 months ago IST
Nearly 7 million years ago, modern humans diverged from our chimpanzee ancestors, yet we have since continued to evolve. Within the human lineage, 155 novel genes that spontaneously developed from little fragments of our DNA have been discovered. A handful of these "microgenes" are projected

Research throws light on secret language of photosynthesis
Updated : 3 years, 3 months ago IST
Scientists have been perplexed by the signals plants transmit to start photosynthesis, the process of converting sunlight into sugars, for decades. Academics from UC Riverside have finally cracked these earlier enigmatic communications.

Warning signs of sudden cardiac arrest provide opportunity for prevention
Updated : 3 years, 3 months ago IST
Sudden cardiac arrest causes one in five deaths in industrialised countries.2 Most sudden cardiac arrests occur in the community in people not known to be at risk. A cardiac arrhythmia, called ventricular fibrillation, causes the heart to stop pumping and blood flow to cease. If blood flow i

Probiotic bacteria found in fermented foods might help dispel bad breath
Updated : 3 years, 3 months ago IST
Probiotic bacteria usually found in fermented foods, such as yoghurt, sourdough bread, and miso soup, might help dispel the embarrassment of persistent bad breath (halitosis), finds a pooled data analysis of the available evidence, published in the open access journal BMJ Open.
