Israeli scientists develop sniffing robot with locust antennae

The Hindu:Science - 06/02/2023
Locusts have an acute sense of smell, which the researchers in Tel Aviv University have managed to harness to their bio-hybrid robot.

Single-use plastic waste rises from 2019-2021 despite pledges

The Hindu:Science - 06/02/2023
Single-use plastics have emerged as one of the world's most pressing environmental threats.

New method for generating spinning thermal radiation uncovered

Science Daily - 05/02/2023
Researchers have made a groundbreaking discovery in the field of thermal radiation, uncovering a new method for generating spinning thermal radiation in a controlled and efficient manner using artificially structured surfaces, known as metasurfaces.

Voiceless frog discovered in Tanzania

Science Daily - 05/02/2023
Researchers discovered a new species of frog in Africa that has an unusual trait: it's completely silent. The Ukaguru spiny-throated reed frog does not croak, sing or ribbit. Found in Tanzania's Ukaguru Mountains for which it is named, Hyperolius ukaguruensis is among the few frogs around the world that do not vocalize to other frogs.

How species partnerships evolve

Science Daily - 05/02/2023
Biologists explored how symbiotic relationships between species evolve to become specific or general, cooperative or antagonistic.

Harnessing an innate protection against Ebola

Science Daily - 05/02/2023
Researchers have identified a cellular pathway that keeps Ebola virus from exiting human cells, with implications for developing new antivirals.

Study reveals new clues about how 'Earth's thermostat' controls climate

Science Daily - 05/02/2023
Rocks, rain and carbon dioxide help control Earth's climate over thousands of years -- like a thermostat -- through a process called weathering. A new study may improve our understanding of how this thermostat responds as temperatures change.

During dolphin research, engineer discovers new method to possibly improve pharmaceuticals

Science Daily - 05/02/2023
Something you maybe never thought of -- dolphins get kidney stones just like people! Now a researcher is reporting a new method to control the growth of ammonium urate crystals, the substance known to cause kidney stones in dolphins and the findings may not only help dolphins but may also have implications for the pharmaceutical industry.

Study reveals salps play outsize role in damping global warming

Science Daily - 05/02/2023
Humans continue to amplify global warming by emitting billions of tons of carbon dioxide into the atmosphere each year. A new study reveals that an ocean animal called a salp plays an outsize role in damping the impacts of this greenhouse gas by pumping large amounts of carbon from the ocean surface to the deep sea, where it contributes nothing to current warming.

Neighborhood walkability linked to risk of gestational diabetes

Science Daily - 05/02/2023
A new study finds that higher neighborhood walkability is associated with lower risk of gestational diabetes (GD).

A new understanding of reptile coloration

Science Daily - 05/02/2023
Snakes and mice don't look alike. But much of what we know about skin coloration and patterning in vertebrates generally, including in snakes, is based on lab mice. However, there are limits to what mice can tell us about other vertebrates because they don't share all of the same types of color-producing cells, known as chromatophores. To gain a better understanding of the genetic basis of colouration in vertebrates, a research team combined a range of techniques (whole gene sequencing, gene-editing, and electron microscopy) to look more closely at color variations and patterning in the skin shed by ball pythons bred in captivity. They were able to identify a particular gene that plays a crucial role in reptile pigmentation generally and more specifically in a classic colour variant found across vertebrates and distinguished by blotches of white, the piebald.

Ice cores show even dormant volcanoes leak abundant sulfur into the atmosphere

Science Daily - 05/02/2023
Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.

Autonomous driving: New algorithm distributes risk fairly

Science Daily - 05/02/2023
Researchers have developed autonomous driving software which distributes risk on the street in a fair manner. The algorithm contained in the software is considered to be the first to incorporate the 20 ethics recommendations of the EU Commission expert group, thus making significantly more differentiated decisions than previous algorithms. Operation of automated vehicles is to be made significantly safer by assessing the varying degrees of risk to pedestrians and motorists.

Life in a violent country can be years shorter and much less predictable -- even for those not involved in conflict

Science Daily - 05/02/2023
How long people live is less predictable and life expectancy for young people can be as much as 14 years shorter in violent countries, compared to peaceful countries, according to a new study. It reveals a direct link between the uncertainty of living in a violent setting, even for those not directly involved in the violence, and a 'double burden' of shorter and less predictable lives.

People with light skin are at higher risk of skin cancer. How to reduce sun exposure

The Hindu:Science - 05/02/2023
The risk of skin cancer depends on a few things including family history, lifestyle, a personal history of skin cancer and skin pigment.

Vitamins and supplements: What you need to know before taking them

The Hindu:Science - 05/02/2023
In 2020, the global market for complementary and alternative medicines, which includes multivitamin supplements, had an estimated value of USD 82.27 billion.

S.P.K. Gupta: Of unsung scientists and their unsung biographer

The Hindu:Science - 05/02/2023
If the name Yellapragada SubbaRow resonates at all in the popular imagination of today, the credit goes entirely to Gupta.

Deer may serve as a reservoir for old SARS-CoV-2 variants

The Hindu:Science - 05/02/2023
The study found multiple spillover events from humans to deer of the Alpha and Delta lineages, and subsequent transmission among white-tailed deer and adaptation of the viruses in the deer.

Deer may serve as a reservoir for old SARS-CoV-2 variants

The Hindu:Science - 04/02/2023
The study found multiple spillover events from humans to deer of the Alpha and Delta lineages, and subsequent transmission among white-tailed deer and adaptation of the viruses in the deer.
