Researchers at NTNU have managed to show exactly how the tuberculosis bacterium kills its host cell by filming the process in detail for the first time. Every year, 1.5 million people die of TB. Watch the clips below.
Nearly 40 million people were living with HIV in 2017, the UN says, with just over half taking antiretroviral therapy. These drugs have cut AIDS-related deaths by more than half since the 2004 peak, but the disease cannot be cured. A new mechanism uncovered by a Norwegian research group could improve the chances of developing one.
Cholesterol crystals form from “bad” cholesterol and are found in plaques that line blood vessels. When these plaques rupture, they can cause heart attacks or strokes. New research suggests that cholesterol crystals in plaques can actually trigger strokes and heart attacks.
A solid tumour can cause muscle cells in the body to self-destruct. Many cancer patients die from the consequences. Now researchers are discovering more about how cancer cells in a tumour can take control of muscle cell wasting and trigger a chronic, serious condition.
Our immune systems are working overtime this time of year. Knowing that a bunch of dedicated immune cells are willing to explode themselves to inform other cells about the danger may offer a bit of consolation.
The tuberculosis vaccine only works for children. BCG (bacille Calmette-Guerin) doesn’t protect you as an adult. Now we know more about how the bacterium avoids being detected.
The plague that is believed to have caused the Black Death still occasionally ravages populations, albeit to a much smaller extent than before. Now we know more about how the bacteria attack us.
An enzyme found in many bacteria, including the bacterium that gives us strep throat, has given mankind a cheap and effective tool with which to edit our own genes. This technology, called CRISPR, is also being used to understand how the immune system responds to a viral attack.
Some bacteria and viruses take advantage of the way our immune system works to infect us. NTNU researchers are uncovering the mechanisms by which this trickery takes place.

Privacy Policy
The Privacy Statement is about how this website collects and uses visitor information. The statement contains information that you are entitled to when collecting information from our website, and general information about how we treat personal data.The legal owner of the website is the processing officer for the processing of personal data.

As an important part of the effort to create a user-friendly website, we look at the user pattern of those who visit the site. To analyze the information, we use the Google Analytics analysis tool.Google Analytics uses cookies (small text files that the site stores on the user's computer), which registers the users' IP address and provides information about the individual user's online movements. Examples of what the statistics give us answers to are; how many people visit different pages, how long the visit lasts, what websites users come from and what browsers are used. None of the cookies allow us to link information about your use of the site to you as an individual.The information collected by Google Analytics is stored on Google servers in the U.S.. The information received is subject to the Google Privacy Policy.An IP address is defined as a personal information because it can be traced back to a particular hardware and thus to an individual. We use Google Analytics's tracking code to anonymize the IP address before the information is stored and processed by Google. Thus, the stored IP address can not be used to identify the individual user.
2. Search
If the webpage has search function, it stores information about what keywords users use in Google Analytics. The purpose of the storage is to improve our information service. The search usage pattern is stored in aggregate form. Only the keyword is saved and they can not be linked to other information about the users, such as the IP addresses.
3. Share / Tips service
The "Share with others" feature can be used to forward links to the site by email, or to share the content of social networking. Tips for tips are not logged with us, but only used to add the tips to the community. However, we can not guarantee that the online community does not log this information. All such services should therefore be used wisely. If you use the email feature, we only use the provided email addresses to resend the message without any form of storage.
4. Newsletter
The website can send out newsletters by email if you have registered to receive this. In order for us to be able to send e-mail, you must register an e-mail address. Mailchimp is the data processor for the newsletter. The e-mail address is stored in a separate database, not shared with others and deleted when you unsubscribe.

Personal information we receive is not used for purposes other than responding to the inquiry.The form is sent as email via Mailgun as a third party solution. The entire submission will be stored at Mailgun for 24 hours. Between 24 hours and 30 days, only mailheader is stored before the submission is deleted after 30 days. The reason for this storage is to confirm whether emails are sent from the website and forwarded to the correct recipient.Once the email is received by the recipient, it is up to the recipient to determine the data processing needs of the email.
