New infrared microscope helps image biological samples at the microscopic level

Scientists have designed a new spectroscopic microscope to optically measure the orientations and conformations of molecules in biological specimens.

Researchers identify “migration gene” in birds

Researchers have reported that they have found the strongest proof yet of a “migration gene” in birds.

Study provides new information on occurrence of DVL2 gene defect in dogs

A recent genetic study at the University of Helsinki provides new information on the occurrence of a DVL2 gene defect associated with a screw tail and its relevance to canine constitution and health.

Study reveals a major genetic risk factor for severe COVID-19

In 2020, a research team demonstrated that a significant genetic risk factor for severe COVID-19 infection was inherited from Neanderthals.

Birds keep fluffy down feathers between their bodies to survive cold climates

Feathers are a sleek, intricate evolutionary innovation that makes flight possible for birds, but in addition to their stiff, aerodynamic feathers used for flight, birds also keep a layer of soft, fluffy down feathers between their bodies and their outermost feathers to regulate body temperature.

Increases in active mobility can significantly lower carbon footprints, study reveals

Swapping the car for walking, cycling and e-biking even just one day a week makes a significant impact on personal carbon emissions in cities.

Cancer survivors face barriers in maintaining a healthy diet

New research and analysis appearing in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, highlights the barriers cancer survivors face in maintaining a healthy diet, as well as the role nutrition may play in cancer risk and treatment.

Researchers discover genetic risk factor for stroke

A research team from Geisinger Health System has detected a common genetic variant as a risk factor for stroke, particularly in patients aged more than 65.

New technique helps detect dangerous histamine levels in fish samples

For people buying food products, there is no way to determine the safety and quality of food that is delivered to their plates by existing distribution systems.

Study provides evidence of paradigm shift in tackling climate change

A new study co-authored by researchers from the Wildlife Conservation Society's (WCS) Global Conservation Program and the University of British Columbia (UBC) Faculty of Forestry introduces a classification called Resistance-Resilience-Transformation (RRT) that enables the assessment of whether and to what extent a management shift toward transformative action is occurring in conservation.

Speciation process takes place in the presence of maximal gene flow, indicates study

Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.

Researchers show how the genetic material travels from cell to cell

The genetic material of plants, animals, and humans is well protected in the nucleus of each cell and stores all the information that forms an organism. For example, information about the size or color of flowers, hair or fur is predefined here.

Scientists develop novel approach to acquire fluorescence lifetime images

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific wavelength range and then re-emit it at the longer wavelength range.

High-speed atomic force microscopy sheds light on structure, dynamics of intrinsically disordered proteins

Kanazawa University’s pioneering high-speed atomic force microscope technology has now shed light on the structure and dynamics of some of life’s most ubiquitous and inscrutable molecules – intrinsically disordered proteins.

Many light smokers meet the criteria for nicotine addiction

Even people who consider themselves to be casual cigarette smokers may be addicted, according to current diagnostic criteria. Researchers at Penn State College of Medicine and Duke University found that many light smokers -- those who smoke one to four cigarettes per day or fewer -- meet the criteria for nicotine addiction and should therefore be considered for treatment.

Triple drug combination keeps people with metastatic colon cancer disease free for longer time

Researchers from SWOG Cancer Research Network, a cancer clinical trials group funded by the National Cancer Institute (NCI), part of the National Institutes of Health, have shown that a triple drug combination - of irinotecan, cetuximab, and vemurafenib - is a more powerful tumor fighter and keeps people with metastatic colon cancer disease free for a significantly longer period of time compared with patients treated with irinotecan and cetuximab.

Study shows how the brain navigates places and tracks someone else in the same location

As COVID cases rise, physically distancing yourself from other people has never been more important. Now a new UCLA study reveals how your brain navigates places and monitors someone else in the same location.

Researchers analyze the variation in song frequency of passerine bird species

An analysis of the songs of most of the world's passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection.

Novel microscope could allow surgeons to inspect cancer margins in minutes

When surgeons remove cancer, one of the first questions is, "Did they get it all?" Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer.

Researchers use unique DNA markers to tackle rhino poaching

Scientists from the Wildlife Institute of India (WII) have applied DNA markers to offer forensic proof for suspected poaching cases that involved the Indian rhino.
