New approach to drug delivery combines biologics and antibody-drug conjugates

The Hindu:Science - 15/05/2021
This could have impact on incurable diseases, so-called undruggable ones like pancreatic cancer

Coronavirus | Testing and the importance of low positivity rate

The Hindu:Science - 15/05/2021
Although the second wave came more than a year after the first, India’s testing infrastructure remained insufficient and underprepared

New species of skink found from Western Ghats

The Hindu:Science - 15/05/2021
Skinks are non-venoumous, their inconspicuous limbs make them resemble snakes

New technology enables rapid sequencing of entire genomes of plant pathogens

Science Daily - 15/05/2021
Next-generation sequencing technology has made it easier than ever for quick diagnosis of plant diseases.

Fibre-optics used to take the temperature of Greenland Ice Sheet

Science Daily - 15/05/2021
Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world's second-largest ice sheet, as the effects of climate change continue to accelerate.

Harvesting light like nature does

Science Daily - 15/05/2021
A new class of bio-inspired two-dimensional (2D) hybrid nanomaterials mimic the ability of photosynthetic plants and bacteria.

People at high genetic risk for colorectal cancer benefit more from lifestyle changes

Science Daily - 15/05/2021
People with a high polygenic risk score for colorectal cancer could benefit more at preventing the disease by leading healthy lifestyles than those at lower genetic risk, according to a new study.

Path of light in photosynthesis traced

Science Daily - 15/05/2021
Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food.

New cyanobacteria species spotlights early life

Science Daily - 15/05/2021
Cyanobacteria first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms. Researchers have discovered a new species of cyanobacteria, Anthocerotibacter panamensis, which could help illuminate how photosynthesis evolved to create the world as we know it.

New pre-clinical model could hold the key to better HIV treatments

Science Daily - 14/05/2021
Researchers have developed a unique pre-clinical model that enables the study of long-term HIV infection, and the testing of new therapies aimed at curing the disease.

Sensors can identify threats at the molecular level

Science Daily - 14/05/2021
New sensors developed by researchers can identify explosive materials, particles from a potentially deadly virus and illegal drugs at the part-per-quadrillion level.

New research optimizes body's own immune system to fight cancer

Science Daily - 14/05/2021
A new study shows how engineered immune cells move faster to attack tumors.

Virtual reality warps your sense of time

Science Daily - 14/05/2021
Psychology researchers found that playing games in virtual reality creates an effect called 'time compression,' where time goes by faster than you think. The research team compared time perception during gameplay using conventional monitors and virtual reality to determine that this effect is uniquely linked to the virtual reality format.

Our dreams' weirdness might be why we have them, argues new AI-inspired theory of dreaming

Science Daily - 14/05/2021
Why we dream is a divisive topic within the scientific community, and the neuroscience field is saturated with hypotheses. Inspired by techniques used to train deep neural networks, a neuroscience researcher argues for a new theory of dreams: the overfitted brain hypothesis. The hypothesis suggests that the strangeness of our dreams serves to help our brains better generalize our day-to-day experiences.

Mammals can use their intestines to breathe

Science Daily - 14/05/2021
Rodents and pigs share with certain aquatic organisms the ability to use their intestines for respiration, finds a study publishing May 14th in the journal Med. The researchers demonstrated that the delivery of oxygen gas or oxygenated liquid through the rectum provided vital rescue to two mammalian models of respiratory failure.

Earth's oldest minerals date onset of plate tectonics to 3.6 billion years ago

Science Daily - 14/05/2021
Scientists provide new evidence that modern plate tectonics, a defining feature of Earth and its unique ability to support life, emerged roughly 3.6 billion years ago. The study uses zircons, the oldest minerals ever found on Earth, to peer back into the planet's ancient past.

Climate change threatens one-third of global food production

Science Daily - 14/05/2021
New research assesses just how global food production will be affected if greenhouse gas emissions are left uncut.

Researchers develop 3D-printed jelly

Science Daily - 14/05/2021
3D-printable gels with improved and highly controlled properties can be created by merging micro- and nano-sized networks of the same materials harnessed from seaweed. The findings could have applications in biomedical materials - think of biological scaffolds for growing cells - and soft robotics.

Herbivores developed powerful jaws to digest tougher plants after the mass extinctions

Science Daily - 14/05/2021
The evolution of herbivores is linked to the plants that survived and adapted after the 'great dying', when over 90% of the world's species were wiped out 252 million years ago.

New immunotherapy 'highly effective' against hepatitis B

Science Daily - 14/05/2021
Scientists have identified a new immunotherapy to combat the hepatitis B virus (HBV), the most common cause of liver cancer in the world.
